SDA 11 Land at North West Heathfield
Chapter 13: SDA 11 – Land at North-west Heathfield SITE CONTEXT 13.1 Strategic Development Area (SDA) 11 is located on the north-western edge of Heathfield. It is situated between Heathfield High Street (A265) and the complex of woodlands that dominate open countryside to the north. The SDA is situated on the northern side of a ridge and is approximately 150m O.D. at its highest point i.e. along its southern limit. It then slopes northwards to approximately 115m O.D. at its lowest point. The National Grid Reference for the centre of the SDA is TQ 574 215. At the time of the survey, the SDA collectively measured 9.33 hectares (ha) in size. 13.2 For the purpose of the survey, SDA 11 (see Appendix: Habitat Map) has been divided into the following six Sub-areas based on land ownership: Sub-area 1 – Tilsmore Lodge (1.87ha) Sub-area 2 – Land at Tilsmore Nurseries (1.45ha) Sub-area 3 – Land to the rear of Rothershaw (1.15ha) Sub-area 4 – Land adjacent to the Police Station including Reynards and Woodhatch (4.5ha) Sub-area 5 – Holmhurst, High Street (0.17ha) Sub-area 6 – Lavender Cottage (0.19ha) 13.3 The SDA comprises irregularly shaped, but connected parcels of land, broadly orientated from west (Sub-area 1) to east (Sub-area 4), north of residential properties along the A265. Four residential properties and their associated grounds are included within the SDA. These include Sub-areas 5 and 6, which are discrete sites, and a section of Subarea 4 extending southwards to include two other properties. All four of these houses front onto the A265. The remaining Sub-areas all have houses adjacent to their southern boundaries. 13.4 The majority of the SDA forms part of the statutory designated High Weald Area of Outstanding Natural Beauty1 (AONB). There are no statutory or non-statutory designated nature conservation sites within or adjacent to the SDA boundary. There is a small area of 1 Areas of Outstanding Natural Beauty are areas of high scenic quality that have statutory protection under the National Parks and Access to the Countryside Act 1949, in order to conserve and enhance the natural beauty of their landscapes. There are 38 AONBs in England and Wales. They are designated by Natural England under the Countryside and Rights of Way Act 2000. They differ from National Parks in their more limited opportunities for extensive outdoor recreation and the way that they are managed without a dedicated authority. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1096 Ancient Semi-Natural Woodland (ASNW) present within the SDA (Sub-area 3) with ASNW also contiguous with other parts of the SDA boundary (see Ancient Woodland description below). The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1097 DESK STUDY FOR SDA 11: LAND AT NORTH-WEST HEATHFIELD 13.5 The following information regarding the present and historical ecological interest of the SDA, covering a 2km radius search area, was supplied by SxBRC, Wealden District Council and on-line mapping services: Ancient Woodland 13.6 There are twenty-four areas of ASNW within a 2km radius of SDA 11. The closest of these is Markly Wood which is located immediately to the north of the SDA. This is a 160ha Planted Ancient Woodland (PAW) which is contiguous with the northern boundary of Subarea 4, the north-western boundary of Sub-area 1 and forms part of the northern limit of Sub-area 3. This PAW contains large areas of ghyll woodland which run adjacent to the northern boundary of Sub-area 2, extending into the SDA along the northern boundary of Sub-area 3, before heading north-east. Ghyll woodland also runs adjacent to the northeastern corner of Sub-area 4 before heading north-west to join with other off-site ghylls. Heatherden Wood (25ha) is located south-west of SDA 11 (on the south side of Heathfield High Street (A265) and also contains ghyll woodland. All remaining areas of woodland to the south are fragmented and isolated from the SDA due to urban development. Designated Landscape 13.7 The majority of SDA 11 is located within the Statutory Designated High Weald AONB, whose boundary cuts across the southern extent of the SDA. The southern parts of Subareas 1, 4, 5 and 6 are situated outside, but adjacent to the AONB. The High Weald AONB comprises the area between the North and South Downs, which are the outer chalk rims of the ancient Wealden anticline. Sandstones and clays are exposed in the centre of the dome, producing a hilly countryside of ridges and valleys with small, irregular shaped fields, abundant small ancient woods, ghylls and shaws, scattered settlements, ancient routeways and sunken lanes. Biodiversity Opportunity Areas 13.8 Sub-areas 2-4 are within Heathfield Habitat Link Biodiversity Opportunity Area (BOA) identifying them as priority areas for the delivery of Biodiversity Action Plan (BAP) targets2. Targets for this BOA include the sympathetic management of habitat mosaics present within the BOA and to increase the ‘permeability’ of the landscape for wildlife (South East England Biodiversity Forum, 2009). 2 Biodiversity Opportunity Areas are identified at a regional spatial scale as areas of opportunity for restoration and creation of BAP habitats. They do not include opportunities for all BAP habitats present in the region or identify all areas where these could be applied. Work is still needed to develop opportunity areas in urban and marine environments in particular. Each BOA has its own area statement with targets. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1098 Designated Nature Conservation Sites 13.9 There is one statutory designated site for nature conservation located within 2km of the SDA. This is Heathfield Park Site of Special Scientific Interest (SSSI) located 1.6km to the east of Sub-area 4. A summary of the citation for this 41ha designated site is below (SxBRC, 2011): Table 1: Heathfield Park SSSI Citation ‚The site is an example of ancient Wealden ghyll woodland formed by the vigorous downcutting of a stream into the Ashdown Sand series of the Hastings Beds. A number of ‘Atlantic’ plants, uncommon in the south-east, are present and the lichen flora is also notable. The stream has been dammed to form a series of lakes, the northernmost of which are included in the site and add to its interest. The woodland is dominated by mature beech Fagus sylvatica with both pedunculate and sessile oak Quercus robur and Q. petraea, holly Ilex aquifolium and scattered yew Taxus baccata. In the north and east birch Betula spp. becomes frequent and the stream valleys contain willow Salix spp. and alder Alnus glutinosa. Where beech is dense only the moss Leucobryum glaucum gives ground cover, but where the canopy is more open bracken Pteridium aquilinum and bramble Rubus fruticosus are found with rhododendron Rhododendron ponticum invading in places. Continuous woodland cover in this sheltered ghyll provides a moist, mild microclimate and a number of plant species occur here which are otherwise restricted to western counties, including Cornish moneywort Sibthorpia europaea, hay-scented buckler-fern Dryopteris aemula and the liverwort Frullania tamarisci. The site is also of county importance for lichens: a total of 76 species have been recorded here, mostly from the old oaks. The lakes add to the value of the site for dragonflies and birds. Great reedmace Typha latifolia forms fringing vegetation and the open water is dominated by white and yellow water-lilies Nymphaea alba and Nuphar lutea‛. 13.10 There are two non-statutory designated sites within a 2km radius of the SDA, the nearest of which is Oaken & Furlong Woods Site of Nature Conservation Importance (SNCI) located 1.75km to the north-east Sub-area 4 (see Table 2 below). The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1099 Table 2: Sites of Nature Conservation Importance within a 2km radius of SDA 11 Site Name Oaken & Furlong Woods Meer’s & Hornslodge Ghyll Complex Reason for designation Part of a woodland complex which includes Great Furnace and North Down Woods. The wood is mostly very old, hornbeam coppice of which some is neglected, with scattered hazel, oak and sweet chestnut, a few standards and a bluebell ground flora typical of Wealden woods. The most interesting feature of the wood is the important "Atlantic" moss and fern community associated with the ghyll flora and outcrops of sandstone. The canopy here is similar to the rest of the wood, but with occasional ash, beech, alder and sallow. Localised base-enriched flushes are also evident in the wood, with field maple, and there is secondary woodland growth on old fields nearby. There is also evidence of past mineral extraction within the woods. A woodland complex consisting of a narrow area of woodland along a ghyll stream. The woodland is predominated by hornbeam coppice, with some ash, hazel and sweet chestnut coppice occasionally. The ground flora throughout the woodland is dominated by bluebells and wood anemones with patches of moschatel, lesser celandine and stream banks covered in ramsons. Some areas of the ghyll are accessible by sheep and are grazed. Area (ha) Distance from SDA (km) 31.6 1.75 24.0 1.95 Water bodies 13.11 There are a total of 45 ponds present within a 2km radius of SDA 11. These ponds are all relatively small and are scattered throughout the landscape. This figure excludes ghylls and streams (and their connected ponds and lakes) which are characteristic and widely distributed features of the High Weald AONB landscape, adding further to the number of water bodies. The closest off-site ponds (which are on-line) are situated 237m directly north of Sub-area 4, in Markly Wood PAW. Records of Protected and BAP Species 13.12 Records of the following protected, rare, notable and/or invasive species were identified within a 2km radius of SDA 11 using data provided by SxBRC. Plants 13.13 There is a 1996 record for spiked rampion from Cross in Hand (Brown’s Lane) which is approximately 1.35km to the south-west of Sub-area 1. This plant is confined to East Sussex and is a UK BAP priority species given special protection under Schedule 8 3 of 3 Schedule 8 of the Wildlife and Countryside Act 1981 (as amended) relates to protected plants and fungi. All wild plants in Britain are protected from intentional uprooting by an unauthorised person. Schedule 8 plant species (see www.naturenet.net/law/sched8.html) are given additional protection as intentional picking, uprooting, destroying, trading (including parts and derivatives) etc. are all prohibited. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1100 the Wildlife and Countryside Act 1981 (as amended). There are currently only a few records within the county, from the Heathfield and Hailsham areas. 13.14 A 1990 record for hay-scented buckler-fern was returned from Little London (The Spinney) approximately 2km south-west of Sub-area 4. This species is rare in the county. 13.15 There are two 2006 records for common wintergreen from Markly Wood, the closest being approximately 1km north-east of Sub-area 4. This species is rare in the county. 13.16 There are five records for Cornish moneywort within a 2km radius of SDA 11. The closest of these is from 2007, 1.35km east of Sub-area 4. This species is rare in the county. Invertebrates 13.17 Notable and rare invertebrates which are all Species of Principal Importance for Biodiversity4 that have been recorded within the 2km data search area, and for which suitable habitat is present within the SDA, are as follows: Oak hook-tip White admiral Small Phoenix Buff ermine Dot Moth Mouse moth Knot grass Rustic Mottled rustic Rosy Rustic Birds 13.18 There are records for 65 species of birds within the search area, including 13 Birds of Conservation Concern5 (BoCC) Red List species and 16 BoCC Amber List species. Many 4 5 Section 41 (S41) of the NERC Act (2006) includes a published list of habitats and species which are of principal importance for the conservation of biodiversity in England. It is used to guide decision-makers such as LPAs in implementing their duty under section 40 of the NERC Act (2006), to have regard to the conservation of biodiversity in England, when carrying out their normal functions (see Chapter 16 and 17). Birds of Conservation Concern status is prioritised into high concern (Red), medium concern (Amber) and low concern (Green) (Eaton et al, 2009). Red-list species are those that are globally threatened according to the IUCN criteria; those whose population or range has declined rapidly in recent years; and those that have declined historically and not shown a substantial recent recovery. Amber-list species are those with an unfavourable conservation status in Europe; those whose population or range has declined moderately in recent years; those The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1101 of these species require habitats not present at SDA 11, but examples of BoCC Red List that may use the SDA due to the habitats present include cuckoo, song thrush, linnet and yellowhammer. All four of these species are UK BAP species (JNCC, 2010) and under the Natural Environment and Rural Communities (NERC) Act (2006) are Species of Principal Importance for Biodiversity. Bats 13.19 There are records for seven different bat species including; noctule, serotine, whiskered/Brandt's bat, Natterer’s bat, Daubenton's bat, brown long-eared, common pipistrelle and unidentified pipistrelle species. The most recent and closest record is for a 2004 Natterer’s hibernation roost at Tilsmore Tunnel, 40m east of Sub-area 4. Reptiles 13.20 The following reptile species have been recorded within the search area: Four slow-worm records, the closest being a 2006 record at Ghyll Road, Heathfield, 1.2km south of Sub-area 4; Four common lizard records, the closest being a 1990 record at Heathfield Park 1.86km south-east of Sub-area 4; Eight records of grass snake, the closest being a 1997 record 428m south of Subarea 4; and One record of adder, the closest being a 2006 record from Waldron Ghyll 1.2km south of the Sub-area 4. Great crested newt /amphibians 13.21 There are four records of great crested newt within the 2km search area, the closest being a 2006 record at Waldron Ghyll, 1.2km south of Sub-area 4. Five records of common toad (UK BAP priority species) were also returned, with the closest record being from 2007 at Geers Wood, 903m south of Sub-area 4. Dormouse 13.22 There are two records of dormouse within the 2km search area, the closest being a 1998 record at Sellyns Farm, Cross in Hand, 1.35km west of Sub-area 1. Water vole 13.23 There is one record of water vole within the 2km search area from 2001, recorded at High Meadows Lake, Mayfield Flat Farm, 1.88km north-west of SDA 11. whose population has declined historically but made a substantial recent recovery; rare breeders; and those with internationally important or localised populations. Green-list species are those that fulfil none of the criteria. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1102 Invasive plant species 13.24 The data search returned a high number of records for invasive plant and animal species that may potentially be present within the SDA. Invasive plant species listed on Schedule 9 of the Wildlife and Countryside Act 1981 (as amended) most likely to be present within on-site habitats are three-cornered garlic, montbretia, variegated yellow archangel, rhododendron, cotoneaster spp, Indian balsam, New Zealand pygmyweed and Nuttall's Waterweed. The last four species are aquatic species that can be found in areas of standing water. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1103 HABITAT SURVEY: OVERVIEW OF SDA 11 13.25 SDA 11 includes six Sub-areas. The largest of these is Sub-area 4 which comprises 48% of the total SDA area. Apart from Sub-area 1, the Sub-areas are connected together and are broadly orientated from west (Sub-area 1) to east (Sub-area 4). Sub-areas 5 and 6 are small residential properties to the south of Sub-area 4 and constitute less than 4% of the total area. 13.26 Habitats present within the overall strategic development survey area included a moderate diversity of grassland types consisting of unimproved acid, semi-improved acid, marshy, poor semi-improved and improved grassland. The external and internal boundaries of the SDA comprised woodland, scattered tree, scrub and hedgerows. These were dominated by native species, but with mixed woodland present in Sub-area 3, including a small area of PAW. Other habitat present included: running and standing water, dry ditches, earth banks, bracken and tall ruderal, along with hardstanding, buildings and private gardens with introduced shrubs. HABITAT SURVEY: SUB-AREA 1 - TILSMORE LODGE Overview 13.27 All parts of Sub-area 1 were surveyed on the 24th May 2011. The Sub-area is 1.87ha in size, forms part of the Tilsmore Estate and is currently unmanaged. The SDA is accessed from the A265 via land between Tilsmore Lodge and Tilmore Cottage. Markly Wood Planted Ancient Woodland forms the north and west boundary. Broad-leaved seminatural woodland forms the northern and eastern boundary, and gardens of properties on the A265 delimit the south boundary. It is connected to Sub-area 2 via off-site woodland in the eastern corner, which includes the head of an off-site (but adjacent) ghyll. Habitats present within the Sub-area included: unimproved acid, marshy and poor-semi-improved grassland, broad-leaved semi-natural woodland, scattered trees, continuous and scattered scrub, tall ruderal and bracken. Broad-leaved semi-natural woodland 13.28 Secondary woodland and woodland edge was dominated by pedunculate oak with some sweet chestnut, holly, hazel and ash (each also present as coppiced stools). The shrub layer included occasional mountain ash and invading rhododendron (T1). The ground flora was dominated by bluebell (mainly the pure native species, but some areas dominated by hybrid bluebell). Dead standing, fallen and buried wood (mainly sweet chestnut and oak) was present in good quantity. Scattered trees and scrub 13.29 Lines of mature open-grown pedunculate oaks dominated the Sub-area and were associated with banks and/or ditches and usually marked internal compartments. In The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1104 some areas these mature trees had spread to form strips of secondary woodland, while in other areas they had been cleared – including very recently. Scattered trees and scrub included frequent to occasional pedunculate oak (including a large amount of self-seeded specimens), downy birch, silver birch, beech, sweet chestnut and holly. Dense bramble scrub was present around the edges of the grassland and as discrete pockets within it. Woodland ground flora, including wood anemone, enchanter’s nightshade and hard fern, appeared to be recolonising from adjoining sections of woodland and hedgerows. Flytipped garden waste of potential value to hibernating reptiles was present adjacent to a property on the southern boundary (T4). Unimproved acid grassland 13.30 Unimproved mildly acid grassland was present in the east of the Sub-area. Sweet vernal grass dominated with occasional oval sedge, cock’s-foot, timothy and Yorkshire fog. Abundant wildflowers included two orchid species common twayblade, common spotted orchid (T3), as well as hybrid cinquefoil, yarrow, bugle, heath speedwell, germander speedwell, heath bedstraw and a single bush of common heather. The more westerly field was not as botanically rich, probably having been overgrazed in the past, but is likely to be recovering due to the current change in management. Acid grassland to the north (bordering the marshy grassland) was also less diverse and comprised similar grass species, but with the addition of common bent, common sorrel and rough meadow grass (the latter in drier areas). A colony of the invasive plant species – montbretia was present adjacent to a property on the southern boundary (T5). Marshy grassland 13.31 The acid grassland drains north-east into an area of rush pasture with abundant soft rush and frequent compact rush, marsh thistle, bugle and greater bird’s-foot-trefoil. Other wetland indicators included angelica and pink water speedwell. Ferns were frequent across this habitat including lady fern, male fern and narrow buckler-fern (T2). Tall ruderal / bracken 13.32 Small stands of bracken had formed patches along the field edges. Large stands of broad-leaved dock bordered the area of marshy grassland. Fauna 13.33 Abundant bird song was heard within and adjacent to the Sub-area. The following bird species were recorded during the survey; guinea fowl, pheasant, great tit, chiffchaff, bluetit and wood pigeon. Roe deer and rabbit were also present. 13.34 During the survey of the grassland a range of damselflies were observed, including the white-legged damselfly (which has a marked southern distribution in England), as well as The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1105 large red and common blue. Common blue, large white and large skipper butterfly were also present. Target Notes relevant to Sub-area 1 13.35 Target Notes (T) are features within the Sub-area assessed as being of ecological interest and are marked on the Habitat Map in Appendix. Target Note 1 13.36 Invasive plant species – rhododendron Target Note 2 13.37 Rush and fern species in marshy grassland Target Note 3 13.38 Orchid species in unimproved acid grassland Target Note 4 13.39 Fly-tipped garden waste of potential value to reptiles Target Note 5 13.40 Invasive plant species – montbretia The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1106 PROTECTED SPECIES RISK ASSESSMENT: SUB-AREA 1 - TILSMORE LODGE 13.41 The habitats at Sub-area 1 were evaluated as to their likelihood to provide sheltering, roosting, nesting and foraging habitat for the following species/species groups: Breeding birds Bats Badgers Reptiles Great crested newt Dormice Invasive plant species 13.42 These species were selected for further consideration because the results of the desk study revealed that they occur in the vicinity of the SDA and potentially suitable habitat is present within Sub-area 1. The results of the field survey, combined with information from the desk study, are presented in Table 3 below. The relevant legislation and policies relating to protected species is presented within Chapter 16 and 17. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1107 Table 3: Assessment of potential presence of invasive and protected species within Sub-area 1 of SDA 11 Species Main legislation (see Chapter 16) Reason for consideration Likelihood of occurrence HIGH. Areas of suitable breeding habitat (woodland, scattered trees and scrub) for a variety of species are present around the external and internal boundaries. The Sub-area is well connected to off-site foraging resources in the wider countryside, particularly Markly Wood to the north. 65 species recorded within a 2km radius of the SDA. Whilst only 6 bird species were recorded during the survey abundant bird activity was noted. HIGH (roosting) HIGH (foraging). Extensive areas of connected woodland (including PAW and ghyll woodland) stretch to the west, north and east providing both suitable roosting and foraging opportunities. Foraging habitat is of good quality, but limited in size. No buildings were present. Lines of mature pedunculate oak trees, marking internal compartments, are of potential value to roosting bats with features such as split branches, rot holes present etc. Seven bat species are recorded within a 2km radius of the SDA including a Natterer’s hibernation roost 300m east of Sub-area 1. Breeding birds Wildlife and Countryside Act 1981 (as amended) selected species Schedules 1 and 8. Woodland, scattered trees and scrub provide suitable breeding habitat for both common garden species and woodland species. Open countryside to east, north and west (and gardens to the south) provides a wider foraging network. Bats Wildlife and Countryside Act 1981 (as amended) Schedule 5. The Conservation of Habitats and Species Regulations 2010 Schedule 2. Badger Protection of Badgers Act 1992. Mature/semi-mature scattered trees provide suitable roosting habitat. Adjacent woodland complex provides extensive off-site foraging, commuting and roosting habitat. Mosaic of grassland, tall ruderal and scrub provides a small area of good foraging habitat. The Sub-area is located on the north-western edge of Heathfield with excellent connectivity with open countryside to the west, north and east. Widespread and wide-ranging species, especially in the south and west of the UK. Woodland, tree and scrub habitat with occasional raised banks is suitable for sett-building. Fields and scrub provide good foraging habitat. Widespread reptiles Wildlife and Countryside Act, 1981 (as amended) Schedule 5 (partial protection) Boundary vegetation including woodland edge with banks, standing/fallen deadwood and dense scrub provides potential hibernating MEDIUM. The Sub-area and adjacent habitat included good cover and connectivity for badger to move across the wider landscape viz. woodland, scattered trees and scrub. Woodland banks provided suitable topography for sett construction. More open areas of grassland with a shorter sward and bramble scrub provided optimum foraging habitat, but were limited in area. A preliminary search did not find any signs of badger, but this does not guarantee their absence as they are a mobile species. Badger records are not provided as part of the SxBRC data search. HIGH. All areas apart from the more shaded woodland and scattered tree/scrub habitat around the boundary are of high value to reptiles. The area is undisturbed and not accessed by the public. Grassland, tall-ruderal and scrub mosaic provides The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1108 Table 3: Assessment of potential presence of invasive and protected species within Sub-area 1 of SDA 11 Species Main legislation (see Chapter 16) Reason for consideration Likelihood of occurrence habitat. Mosaic of grassland, tallruderal and scrub provides basking and foraging opportunities for widespread species of reptile. optimal habitat for widespread reptile species. This Sub-area is located in a rural location and connected to suitable habitat to the south-east, south and southwest (including large woodland gardens) which may be used by wide-ranging species such as grass snake. Large piles of garden waste in the south provide additional egg-laying and hibernating sites. There are off-site records for all four species of widespread reptile from the data search, the closest being a 1997 grass snake record 868m to the south of Sub-area 1. MEDIUM. The nearest pond is the recently created pond in Sub-area 2 approximately 125m east of Sub-area 1. This pond provides very limited suitable breeding habitat. No ponds are present within Sub-area 1, but marshy grassland may occasionally provide temporary standing water, but for limited periods of the year. The Sub-area is contiguous with Markly Wood and provides optimum terrestrial habitat. Woodland, woodland banks, mature trees and dense scrub provide good hibernating habitat. There are four records for great crested newt within a 2km radius of the SDA. There are no records within 500m of the Sub-area the closest being a 2006 record at Waldron Ghyll, 1.5km south of Sub-area 1. Three ponds within 500m are visible on OS mapping, all in Markly Wood to the north, the closest of which is 420m from the Sub-area. There are no barriers to dispersal, but the presence of abundant habitat around these ponds may limit the need for animals to disperse to the Sub-area. MEDIUM. Potentially suitable on-site habitat is limited to the woodland on the western boundary and scattered trees and scrub around the west, north and east boundary. Whilst these are relatively small in area they are contiguous with the large woodland complex to the north (Tilsmore Wood). The structure of the on-site woodland is sub-optimal but groups of trees and scrub are well connected and dense. Foraging and nest building plants were present in varying quantities, including hazel Great crested newt Wildlife and Countryside Act 1981 (as amended) Schedule 5. The Conservation of Habitats and Species Regulations 2010 Schedule 2. No ponds are present, but suitable terrestrial habitat is found particularly on habitat boundaries. Three ponds identified within a 500m radius, which is the guideline distance (English Nature, 2001) which great crested newt may commute between breeding ponds and terrestrial sites. The Sub-area is located in a rural setting on the north-west edge of Heathfield. The Sussex countryside has an abundance of shallow ponds suitable as breeding sites. Dormouse Wildlife and Countryside Act 1981 (as amended) Schedule 5. The Conservation of Habitats and Species Regulations 2010 Schedule 2. Linear boundary features viz. woodland, and trees/scrub provide suitable nesting habitat. Food and nesting building plants, such as hazel, bramble and honeysuckle were all present.

As such there is potential for invasive plants to be present in the Sub-area. Likelihood of occurrence (occasional), honeysuckle (rare), bramble (abundant) and hawthorn (rare). A 1998 data record was returned from Cross in Hand (Sellyns Farm) 1.35km west of Sub-area 1. PRESENT. Rhododendron and montbretia were recorded within woodland and are included as invasive plant species under Schedule 9 of the Wildlife and Countryside Act 1981 (as amended). The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1110 NATURE CONSERVATION EVALUATION: SUB-AREA 1 - TILSMORE LODGE 13.43 On the basis of the information available from the Phase 1 habitat survey, data search and review of BAPs, Sub-area 1 has been evaluated in terms of its potential for biodiversity, support of protected species and habitats, and the contribution the area makes as part of the wider landscape. A combined evaluation of the nature conservation value of the site using standard criteria developed by IEEM (2006) and selected criteria from Defra's (2006) 'Local Sites' evaluation guidance is provided in Table 4 below. 13.44 The biodiversity value of protected and BAP species within the Sub-area is a preliminary evaluation based upon the desk study records, habitat suitability and the conservation status of the species in question. It should be noted that where European Protected Species or BAP species are present on-site they may be valued at a lower level/scale where it is considered likely that populations would not be of sufficient importance to justify designation at a higher level. However, regardless of their biodiversity value, such species are still subject to national and/or European legislation. 13.45 Key aspects of relevant planning policy and legislation regarding conservation, including an explanation of species referred to as being of 'Principal Importance for the Conservation of Biodiversity', European Protected Species and BAP species and habitats, are provided in Chapters 16-18. Table 4: Combined Evaluation of the Nature Conservation Value of Sub-area 1 of SDA 11 Criteria 6 Remarks Features of International Importance Sub-area 1 is not subject to any international statutory nature conservation designations. The closest site of International Importance is Ashdown Forest designated as both a SAC and SPA, located approximately 11.5km to the north-west. Ashdown Forest is important for its lowland wet and dry heath habitats and associated bird assemblage. No heathland habitat or any supporting habitats that maintain the integrity of this designated area are present within the Sub-area. Features of National Importance Sub-area 1 is not subject to any national nature conservation designations. It is not considered that any habitats or populations or assemblages of species within the Sub-area would meet the criteria for the designation of 6 SSSIs at an appropriate geographic level . Features of Regional (Sussex) Value Sub-area 1 is not subject to any non-statutory nature conservation designations. The south-eastern corner of the Sub-area is adjacent to the source of a ghyll flowing north into Markly Wood PAW. The Weald area of South-East England contains a concentration of ghyll woodland which is included under the county’s Woodland BAP and significant at this level.

Whilst this grassland resource does not fall within the category of lowland heathland or dry acid grassland (Sussex and UK BAP priority habitats) it is nonetheless an uncommon and declining habitat and is considered to be of ecological value of at least the district level. The grassland resource, in conjunction with mosaics of woodland, trees and scrub habitats, is likely to support a moderately diverse assemblage of invertebrates of value at the district level, particularly in combination with adjacent Sub areas. Features of Local (Heathfield) Importance A number of protected and UK/Sussex BAP species may occur at the Sub-area as follows: - Reptiles including slow-worm, common lizard, grass snake and adder; - Birds such as house sparrow, cuckoo, starling, dunnock, linnet, song thrush and bullfinch; - Amphibians such as great crested newt and toads; - Invertebrates such as stag beetle; - Small mammals such as hedgehog and dormice; and - Bats, such as soprano, noctule bat and brown long eared. Based on the quality and extent of habitat present, it is considered that populations of these species would be significant at the local level. There is a single UK BAP priority habitat present on-site: lowland mixed deciduous woodland (see Habitat Map) although this habitat is limited in extent and not considered to be an outstanding example of its type, it is therefore of no more than local importance. The Sub-area is not managed or publically accessible and therefore woodland, scattered trees and scrub are relatively undisturbed and provide cover and foraging opportunities for a breeding bird assemblage of value in a local context. Mature pedunculate oak trees are important ecological features due to their age and potential to support a wide range of species/species groups, including bats, birds, reptiles/amphibians (at their base/roots) and invertebrates (including saproxylic species in standing and fallen deadwood). They are replaceable in only the long-term i.e. 50-100+ years and are considered to be of value at the local level. Features of Value within the immediate vicinity of the Sub-area The remaining habitats at the Sub-area comprising poor semi-improved and improved grassland are likely to be of some value as foraging, cover and breeding sites for a range of generalist species and therefore of value in maintaining the ecology of the area. However, they are common and widespread habitats that do not generally support rare species or diverse assemblages of species and are therefore of value in the immediate vicinity of the Sub-area. Features of Secondary and Supporting Value / Connectivity within the landscape The woodland may provide connectivity between off-site ecological receptors such as small fields, woodland units, hedgerows and tree lines (see above). Woodland and scattered trees and scrub may provide a buffer to ancient woodland (PAW) to the south and west. It extends the foraging and breeding range for off-site species using the adjacent woodland complex. The Sub-area may also function as a buffer to the urban edge of Heathfield and potentially provides a wildlife corridor and/or stepping stones for mobile species moving across the Heathfield urban-rural The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1112 Table 4: Combined Evaluation of the Nature Conservation Value of Sub-area 1 of SDA 11 Criteria Remarks fringe. Social Value / Recorded History and Cultural Associations This Sub-area is privately owned. It is accessed from A265 between Tilsmore Cottage and Tilsmore Lodge, which judging by the remnant avenue of trees used to be a historic drive into the wider Tilsmore Estate. The primary value of Sub-area 1 is in its amenity and aesthetic value to those residents whose houses back onto the Sub-area, affording them views over the countryside and potential (informal) recreation. No recorded ancient trees were present, although numerous mature pedunculate oak trees were present. Trees receiving TPOs are present at the southern end of the Sub-area and provide visual amenity value (please see Habitat Map for location). Economic value The fields are likely to have been historically grazed, but the Sub-area has remained unmanaged for a number of years. Whilst it is generally recommended that mature oaks be retained, they could potentially be harvested for timber. It may be possible to sell woodland products resulting from cyclical woodland management e.g. firewood, timber, poles, charcoal etc. Due to the small size of on-site woodland opportunities available for income generation these activities would be very limited. All remaining habitats and species do not currently provide a resource that could be exploited for their economic value. Size and extent The Sub-area measures 1.87ha (total SDA area 9.33ha) with woodland, scattered tree and scrub habitats occupying approximately 60%. Mosaics of acid grassland, marshy grassland and tall-ruderal/bracken occupy the remaining 40%. Due to its size the Sub-area supports only a moderate range of habitat types, but these have potential to support a range of BAP and protected species due to their type and geographic location. Fragility The woodland and mature trees are susceptible to ground disturbance. The grassland (acid and marshy) is susceptible to both disturbance and changes in hydrology/drainage which would affect its species composition. It is also (and has already become) susceptible to scrub encroachment and the spread of coarse grassland. Remaining habitats i.e. the bracken and self-established young/semi-mature scattered trees and scrub are relatively recently established would rapidly recover from impacts and can be restored. Typicalness Woodland and associated habitats are typical of their individual types. The grassland resource is typical of lightly acidic Wealden substrates with localised wet areas. Summary of Nature Conservation Evaluation 13.46 On the basis of the above criteria, Sub-area 1 is considered to be of ecological value within at least the Wealden District context due to the presence of wet acid grassland. The Sub-area also appears to form part of the catchment of a ghyll stream flowing into Markly Wood. Due to the restricted distribution of such features in SE England, the Subarea is considered to be of regional importance in terms of maintaining the hydrology of the stream, and boundary habitat would be important in buffering it from the effects of any future development. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1113 13.47 Other habitats in the Sub-area, principally old trees and lowland deciduous woodland are considered to be of local value, as is the juxtaposition of grassland, scrub and scattered trees providing habitat structure for a wide range of species. The Sub-area as a whole, and particularly scrub and woodland at the boundaries, provide buffering and supporting habitat to Markly Wood PAW. Due to its proximity to woodland, and the nature of the habitats present, the Sub-area has potential to support a range of declining and BAP species, and species that are protected at National and European level i.e. badger, reptiles, great crested newts, bats and dormice. The legal and policy implications associated with these species are detailed in Chapter 16 and 17. . The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1114 GREEN INFRASTRUCTURE APPRAISAL: SUB-AREA 1 - TILSMORE LODGE Water bodies and the local catchment area 13.48 Sub-area 1 does not include any standing water such as ponds, but the area of marshy grassland to the north (which is a notable feature of the Sub-area) may contain surface water during the winter months. The source of a ghyll is adjacent to the eastern corner of the Sub-area. Habitat connectivity 13.49 Markly Wood surrounds the west, north and eastern boundaries and consequently Subarea 1 is very well connected to the larger woodland complex located to the north and west of Heathfield, via on-site woodland, scattered trees and scrub, and lines of mature oak trees. These habitats provide a potential wildlife corridor for a range of mobile species such as bats, birds, invertebrates, badgers and small mammals. These species are potentially commuting along the woodland edge, within the Sub-area and moving across the Heathfield urban-rural fringe into the wider Wealden countryside and the Heathfield Habitat Link BOA. Sustainable transport routes/PROW 13.50 Sub-area 1 is privately owned and no Public Right Of Way (PROW) is present. There is currently no network of cycle routes serving the Sub-area. There is currently a private access point into Sub-area 1 from the A265. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1115 CONCLUSIONS AND RECOMMENDATIONS: SUB-AREA 1 - TILSMORE LODGE 13.51 The northern half of Sub-area 1 falls within the boundary of the statutory designated High Weald AONB. Sub-area 1 is not subject to any statutory or non-statutory nature conservation designations. The nearest statutory designated site for nature conservation is Heathfield Park SSSI located 1.9km to the east of Sub-area 1. The nearest nonstatutory designated nature conservation site is Oaken & Furlong Woods SNCI located 2.15km to the north-east of Sub-area 1. On the basis of information available at the time of report production, it is considered unlikely that the Sub-area performs an important supporting role for these sites based upon the type and extent of habitats present within the Sub-area, the features for which the sites are designated, and the degree of connectivity between them. 13.52 Overall, the Sub-area is considered to be of district value due to its grassland resource which includes a mosaic of unimproved mildly acid grassland, marshy grassland and tallruderal/bracken, which are likely to support both widespread species of reptile and a moderately diverse assemblage of invertebrates. 13.53 Remaining habitats in Sub-area 1 are considered to be of ecological value in the local context, due to their potential to support a range of legally protected and BAP species. These include species protected at a National and European level i.e. badger, reptile, great crested newt, bats and dormice. This interest is strongly associated with areas of woodland, scattered trees and scrub that are connected to the larger woodland complex located to the east, north and west. In addition, there are also a good number of mature pedunculate oak trees present, which are also features of value at the local level. 13.54 The Sub-area also provides an important secondary and supporting role to the network of ecological receptors surrounding it, primarily by: Buffering off-site areas of Markly Wood that includes an adjacent area of planted ancient woodland and the adjacent head of a ghyll woodland; and Providing wildlife corridors for species moving between the urban areas of Heathfield and the wider Wealden countryside. 13.55 The following UK BAP habitats/species are present or have potential to be present within the Sub-area: Lowland mixed deciduous woodland; Reptiles, including slow-worm, common lizard, grass snake and adder; The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1116 Birds such as house sparrow, cuckoo, starling, dunnock, linnet, song thrush and bullfinch; Amphibians such as great crested newt and toads; Invertebrates such as stag beetle; Small mammals such as hedgehog and dormice; and Bats, such as soprano pipistrelle, noctule bat and brown long eared. 13.56 BAP habitats/species are not necessarily rare but under Planning Policy Statement 9 (PPS9) and the NERC Act 2006 are all of principal importance for biodiversity (ODPM, 2005) and are of material consideration in the planning process. None of the BAP habitats or populations of BAP species currently known to be present on-site are considered as notable or exceptional examples of their type. Under PPS9 ancient woodland is also a Habitat of Principal Importance for Biodiversity. Although there are no areas classified as ancient woodland, the western boundary is adjacent to Markly Wood PAW and an ancient woodland ground flora appeared to be colonising from adjoining sections of woodland and hedgerows. 13.57 Much of the Sub-area’s current ecological value can be attributed to its geographic location within the High Weald and the relatively undisturbed nature of its on-site habitats. However, opportunities for enhancing the Sub-area for wildlife do exist as it has remained unmanaged for a number of years (see recommendations below). Recommended further surveys relevant to Sub-area 1 Overview 13.58 The surveys recommended below assume the loss of or damage to suitable habitat should the Sub-area be proposed for development. There is potential to avoid and/or limit impacts through habitat retention and protection (see below). The final approach to surveys will have to be based on consideration of detailed proposals for Sub-area 1, though in all cases published best practice should be followed with regard to survey methodology etc. 13.59 To provide a sufficient baseline of data and to mitigate against any potential impact on declining, BAP and protected species/habitats at Sub-area 1, further surveys for reptiles, bats, badger, dormice, great crested newts, invertebrates, lower plants and invasive plants are recommended. Reptiles 13.60 The Sub-area includes the habitat mosaic and vegetation structure suitable for a number of widespread reptile species, including both grass snakes and for adders. There are The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1117 open areas for basking, cover against predation as well as numerous potential hibernation spots. There are foraging opportunities for adders within the unimproved grassland, a habitat that often has a high density of small mammals. The head/source of the ghyll to the east may also provide suitable foraging for grass snakes. 13.61 A minimum of a seven visit reptile survey, following current guidelines (Froglife, 1999, English Nature 2004; Natural England 2011b), should be carried out to establish the presence/absence and distribution of reptiles. The grassland/scrub mosaic and edge habitats should be targeted. The optimum time is generally late spring, from April through June and in the early autumn in September. Where possible, survey effort should be spread across the recording season i.e. March-October Bats 13.62 The habitats within the Sub-area are of high value for bats when judged against current assessment criteria provided by the Bat Conservation Trust (BCT) (2007). This is due to the strong connectivity with the wider landscape, presence of adjacent areas of ancient woodland, mature on-site trees suitable for roosting, good quality and diversity of foraging habitats (woodland and unimproved grassland) and proximity to known roosts. 13.63 Following current guidelines (BCT, 2007) further bat surveys are recommended to assess the presence or potential presence of any bat roosts, as well as the function the Sub-area might provide for foraging and commuting. This should include both tree inspections and activity and emergence surveys. Activity and emergence surveys must be carried out between May and September. Badger 13.64 Although no setts were discovered during the Phase 1 survey the landscape of Sub-area 1 provides a highly suitable area for sett building and foraging. The potential for badgers is substantially increased due to the expanse of adjacent woodland and a good diversity of habitat types for foraging. 13.65 In order to assess the use of the Sub-area by badger a survey should be carried out in all areas of suitable on-site sett-building and foraging habitat to look for signs and evidence of this species. Survey effort should also include suitable off-site areas within a minimum 30m distance of the Sub-area boundary. This is in line with current Natural England recommendations and the possibility of sett disturbance caused by construction activities (Highways Agency, 2001; Natural England, 2007). 13.66 Holes attributed to badger should be classified as well used, partially used or disused in line with the methodology given in the National Badger Survey (Cresswell et al. 1990; The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1118 Wilson et al. 1997). Setts should be classified as main, annexe, subsidiary and outlier (Wilson, Harris & McLaren, 1997). Surveys to identify setts should be carried out in the winter while surveys to establish the level of foraging and the likely impact of loss of foraging habitat and mitigation required should be conducted in the summer. Dormouse 13.67 The woodland and scattered trees and scrub form a continuous habitat layer and one that is contiguous with the surrounding woodland. Apart from during their hibernation phase, dormice are almost exclusively arboreal animals and require such interconnected habitats to forage and commute between sites. This species is particularly susceptible to impacts from habitat fragmentation and any loss or impact to scrub/trees/woodland across the Sub-area could have a significant negative impact. 13.68 Therefore, it is recommended that a survey for this species is carried out. This should be carried out using artificial nesting tubes (standard survey methodology). Surveys should follow best practice as provided in English Nature’s Research Report 524: Surveying Dormice Using Nest Tubes (Chanin and Woods, 2003) and their Dormouse Conservation Handbook (2006). Surveys should be carried out between April and November. Great crested newts 13.69 Woodland edge, scattered trees, scrub and the grassland mosaic provides suitable terrestrial habitat for great crested newts. In addition, there are two ponds and a series of ghylls, springs and wet flushes within a 500m radius of the Sub-area, which is the guideline distance (English Nature, 2001) that great crested newt may commute between breeding ponds. It is therefore recommended that a Habitat Suitability Index (HSI) survey, following Oldham et al (2000), is carried out on all ponds within a 500m radius of the Subarea’s boundaries that do not have significant barriers to dispersal. 13.70 Using the results from the HSI, presence/absence surveys of ponds within 500m of the Sub-area that do not have any significant barriers to dispersal between them and the Sub-area may need to be carried out. Four presence/absence surveys should be carried out following best practice guidelines (English Nature, 2001) between mid-March and mid-June with at least two of these surveys between mid-April and mid-May. 13.71 The requirement for further survey will depend on the quality of the ponds as breeding habitat and the number and distance of suitable breeding ponds from the Sub-area. It is likely that the great majority of suitable on-site habitat around boundaries will be retained. However, surveys are still likely to be required to determine population size (if presence is confirmed), and the degree to which great crested newt are a constraint to any proposed The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1119 development in terms of planning construction works and whether works will require a European Protected Species Mitigation (EPSM) licence. Invertebrates 13.72 Sub-area 1 supports a moderate diversity of habitat types, including those of high value to invertebrates, i.e. unimproved and marshy grassland, woodland, mature oak trees and edge/mosaic habitats. If these habitats are to be affected by development a terrestrial invertebrate survey is recommended. Survey effort should focus on woodland edge and grassland habitats and include a selection of survey methods to assess the range of invertebrate fauna likely to be present on-site. Therefore, surveys may be required to inform impact assessments, establish an acceptable extent of development or to inform mitigation proposals. Lower plants 13.73 The head/source of a ghyll is adjacent to the eastern corner of the Sub-area. Ghyll woodland is a Sussex BAP priority habitat and known to support important disjunct populations of ‘oceanic’ vascular plant and bryophyte species. Ghylls are very susceptible to changes in micro-climate, hydrogeology and physical disturbance. Potential impacts from development that may cause these changes are alterations to the local surface and ground water flow, removal of woodland cover in proximity to the ghyll and erosion and compaction from increased recreation. Therefore, surveys may be required to inform impact assessments, establish an acceptable extent of development or to inform mitigation proposals. Invasive plant species 13.74 Rhododendron and montbretia are present in woodland and scattered trees/scrub habitats. These are invasive plant species included on Schedule 9 of the Wildlife and Countryside Act 1981 (as amended) under which it is an offence to plant or otherwise cause these species to grow in the wild. It is possible that they could be spread during construction works and, therefore, a survey to accurately determine their extent, and inform a method statement to avoid spread, will be required. Outline mitigation relevant to Sub-area 1 Habitat retention and protection 13.75 The area of acid grassland, marshy grassland and tall-ruderal/bracken mosaic is one of the most ecologically important habitats present within the Sub-area and development proposals should seek to retain and enhance this area. 13.76 Woodland along the west boundary provides a buffer to Markly Wood PAW and is both a UK and Sussex BAP priority habitat. Lines of mature pedunculate oaks, marking internal The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1120 boundaries are also a notable ecological feature fulfilling both a landscape and ecological function. Development proposals should seek to retain and enhance both woodland and mature trees/internal boundaries. 13.77 Where the loss of the woodland, mature tree and/or grassland resources, described above, is unavoidable, it will be necessary to carry out any required protected species surveys and mitigation prior to their removal and provide compensation for their loss. 13.78 All construction works taking place in the vicinity of retained woodland, trees and grassland should conform to British Standard 5837:2005 Trees in Relation to Construction. 13.79 Markly Wood PAW is adjacent to the western boundary of the Sub-area. Following Natural England’s Standing Advice on Ancient Woodland (2011a) a minimum buffer of at least 15m in width should be maintained between ancient woodland and any development boundary. Subject to the results of any further ecological surveys and liaison with relevant statutory bodies it may be necessary to increase the width of the buffer zone. 13.80 Drainage channels in close proximity to springs/flushes, feeding streams and/or ghylls should be managed to avoid changes to surface and ground water levels, any discharge of pollution or sediments and the diversion of water away from these habitats. All works near to water courses and wetland features should adhere to best practice guidance to avoid adverse effects upon water quality, such as Pollution Prevention Guidance 5: Works and maintenance in or near water (Environment Agency, 2007). In addition, zones alongside ghyll woodland should remain undisturbed by creating buffer areas. Mitigation for protected species 13.81 Nesting bird habitat: Woodland, woodland edge, scattered trees and dense scrub provide suitable nesting habitat for a variety of bird species. It is recommended that any vegetation clearance affecting nesting habitat should be undertaken outside of the bird nesting season which runs from March to August inclusive. 13.82 Bats and lighting: While different species of bat react differently to night time lighting, research has found that bats are sensitive to artificial lighting and that excessive lighting can delay bats from emerging, thus shortening the time available for foraging, as well as causing bats to move away from suitable foraging grounds or roost sites, to alternative dark areas (Jones, 2000). The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1121 13.83 Currently the whole Sub-area remains dark at night and to minimise impacts on bats from lighting associated with any proposed development it will be necessary to limit light spillage and glare, particularly along the boundary with Markly Wood. This can be achieved by following accepted best practice (Institute of Ecology and Environmental Management 2006, Institute of Lighting Engineers 2007) Habitat compensation relevant to Sub-area 1 13.84 Any compensation planting should draw on best practice with regard to the use of native species of local provenance, avoidance of invasive species, and use of non-native species of known wildlife value provided in Chapter 19. Initial measures to be considered in development proposals for the Sub-area would be as follows: Replacement planting to compensate for any loss of woodland, trees, scrub, grassland etc. should be provided as an integral part of any landscape masterplanning for the Sub-area. This should aim to retain the Sub-area’s value for any protected/UK BAP species confirmed present without recourse to off-site translocation. If development involves the removal of trees with potential to provide habitat for birds and bats then artificial bird and bat boxes should be considered in order to provide replacement nesting/roosting habitat. Habitat enhancement relevant to Sub-area 1 13.85 The following outline proposals for habitat enhancement should be considered as part of detailed proposals for development of Sub-area 1 to ensure that features of local ecological value contribute to the ecology of the District as a whole. Additional generic management recommendations for these features are provided in Chapter 19. Woodland 13.86 The Sub-area has remained unmanaged for a number of years and consequently the coppiced stools within the woodland are becoming over-stood. This, and the development of dense areas of self-established trees and scrub, has created a dense canopy, reducing light levels which may inhibit the growth and development of the woodland ground flora. 13.87 Reinstatement of a coppicing system in neglected areas of woodland is recommended to maintain habitat and structural diversity. Areas with evidence of historical coppicing (multi-stemmed trees with large stools) and with a rich ground flora, that is currently being shaded out, should be targeted for coppicing. Care should be exercised when coppicing areas bordering ghylls as trees/shrubs form an important part of this habitat, helping to The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1122 maintain the particular micro-climate associated with this woodland type. Very old trees should not be coppiced as they may fail to regenerate successfully. Grassland 13.88 Pockets of bramble scrub and young self-established trees are encroaching on the grassland resource and will reduce its species diversity. It is recommended that saplings/young trees within the grass are removed and the scrub edge is cut back on a cyclical basis. The spread of bracken should also be monitored and it may be necessary to manage dense stands by pulling/cutting/chemical treatment etc. Green infrastructure enhancements relevant to Sub-area 1 13.89 The Sub-area is adjacent to Heathfield Habitat Link BOA and any development proposals should consider the BOA targets which seeks to sympathetically manage the habitat mosaic present in the area and increasing the ‘permeability’ of the landscape for wildlife. 13.90 Many of the recommendations for habitat protection, creation and enhancement are likely to benefit both biodiversity and green infrastructure within the District. In order to ensure these issues are adequately addressed at the Sub-area level, specific recommendations referring to issues such as off-site habitat, hydrology, access and landscape are provided below: Scrub and woodland around the boundaries should be largely retained to buffer the adjacent PAW and retain corridors of woodland along the northern edge of Heathfield. Any additional planting should be positioned so as to enhance green corridors on-site. Native tree and shrub species should be typical of the local landscape (High Weald AONB). From a green infrastructure perspective, the retention of springs and marshy grassland will ensure that the natural drainage system for the Sub-area continues to function. Where marshy grassland is to be retained and incorporated within development proposals, it should form part of the wider Sustainable Urban Drainage System (SuDS) for the Sub-area/SDA. Detailed hydrological studies should be carried out to ensure that development does not adversely affect water supply or water quality within the adjacent ghyll stream. SuDS and other pollution control measures may be required to ensure that adverse effects do not occur. Subject to findings of botanical and invertebrate surveys, and hydrological investigations, the creation of a pond within the area of marshy grassland or adjoining scrub could improve conditions for amphibians potentially breeding in the The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1123 locality and strengthen links between any breeding populations associated with nearby ponds e.g. in Sub-area 2. If any proposed development comprises large areas of buildings and hardstanding the use of SuDs schemes, green roofs and walls should be considered to enhance the biodiversity value of the Sub-area, protect water quality and reduce the rate of runoff. The use of native tree and shrub planting and species of known wildlife value in landscape schemes should be considered in detailed landscape proposals as this will provide opportunities for wildlife at the smallest scale of development, ensuring that opportunities for common species are not diminished. 13.91 Further detail on measures to enhance biodiversity and green infrastructure are provided in Chapter 19. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1124 HABITAT SURVEY: SUB-AREA 2 - LAND AT TILSMORE NURSERIES Overview 13.92 All parts of Sub-area 2 were surveyed on the 24th May 2011. The Sub-area is 1.45ha in size, is part of the former Tilsmore Nurseries site which is currently owned and managed by local residents. The grassland is cut once per year in July/August with all arising removed. An adjacent pond had recently been created within the Sub-area. The Sub-area is accessed via gates off Nursery Way. Habitats present within the Sub-area included: unimproved acid and marshy grassland, scattered trees, scattered scrub, bracken, standing and running water. Scattered trees and scrub 13.93 Small groups and larger copses of scattered trees were present around the boundary of the Sub-area and comprised abundant downy birch and locally frequent to occasional aspen, pedunculate oak, mountain ash, holly, grey willow and hornbeam. The shrub layer was notably absent across large parts of this habitat, having either been grazed out or cut. A remnant ancient woodland ground flora was present in the north area bordering the ghyll woodland (T9). Species here included: wild strawberry, bluebell, wood speedwell, common dog-violet, wood anemone and yellow pimpernel. The invasive plant species montbretia, and a tree providing standing deadwood with artificial bird box attached, were present among trees in the south of the Sub-area (T5 and T8 respectively) 13.94 Alder was locally frequent on the east side of the Sub-area marking the route of a spring. This locality also contained compact and soft rush, marsh thistle, common fleabane and water mint. Unimproved acid grassland 13.95 The central area of Sub-area 2 comprised unimproved, mildly acid/neutral grassland with a good diversity of sedges (ten species recorded), an abundance of common spotted orchids, and a damp hollow draining into a recently created pond located to the northeast of the Sub-area. Crested dog’s-tail and sweet vernal-grass tended to dominate although the grass flora was diverse. The higher (drier) slopes support a more open sward with occasional tufts of sheep’s fescue and sheep’s sorrel. Wildflowers included abundant common knapweed and meadow buttercup with occasional bird’s-foot-trefoil and common fleabane. Ox-eye daisy was also notably abundant on this part of the Subarea but was generally absent elsewhere. Pond 13.96 Clumps of yellow flag appeared to have been planted on the margins of the pond (T6) while an undetermined water-lily was undoubtedly planted. The drier grassland around the pond supported a colony of slender St. John’s-wort. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1125 Marshy grassland 13.97 The damp hollow was dominated by a stand of jointed rush and marsh pennywort with frequent lesser spearwort. Ghyll (off-site) 13.98 Ghyll woodland was adjacent to the northern boundary of Sub-area 2 (T7). Deep cuttings supported large amounts of bryophytes and ferns including hard fern, hart’s-tongue fern, broad buckler fern, narrow buckler fern, male fern and lady fern, as well as interesting stands of sedges dominated by pendulous sedge, smooth-stalked sedge, remote sedge and tufted hair-grass. Conocephalum conicum, Lophozia bidentata, Fissidens adiantoides, Fissidens taxifolius, Fissidens dubius and Mnium hornum dominated the bryophyte community. Bracken 13.99 A stand of bracken was noted along the eastern field edge, adjacent to the spring. Fauna 13.100 The following bird species were recorded during the survey; great tit, chiffchaff, blue-tit, wood pigeon and mallard. Good numbers of several bumblebee species were recorded during the survey of grassland, including; Bombus lucorum, Bombus pascorum, Bombus pratorum and Bombus hypnorum. An anecdotal record (from local land owner/resident) for grass snake was also provided.

Open countryside to the east, north and west and gardens to the south provide a wider foraging network. Adjacent woodland complex provides extensive off-site foraging, commuting and roosting habitat. On-site grassland provides an extensive area of foraging habitat. The Sub-area is located on the north-western edge of Heathfield with excellent connectivity with open countryside to the west, north and east. Widespread and wide-ranging species, especially in the south and west of the UK. Scattered tree and scrub habitat is suitable for settbuilding. The grassland provides foraging habitat. HIGH. Areas of suitable breeding habitat are present around the edges of the Sub-area and provide nesting and foraging for a variety of species. The Sub-area is well connected to off-site foraging resources in the wider countryside, particularly Markly Wood to the north. 65 species recorded within a 2km radius of the SDA. Six bird species were recorded during the survey and abundant bird activity was noted. LOW (roosting) HIGH (foraging). Extensive areas of connected woodland (including PAW and ghyll woodland) stretch to the west, north and east providing both suitable roosting, and foraging opportunities. Foraging habitat is of good quality viz. flower-rich grassland. The foraging value of the pond will increase as the marginal and bank vegetation establish more fully. No buildings were present. Semi-mature/mature trees of potential roosting value were very limited. Seven bat species are recorded within a 2km radius of the SDA including a Natterer’s hibernation roost approximately 330m east of Sub-area 2. MEDIUM. The Sub-area and adjacent habitat included good cover and connectivity for badger to move across the wider landscape viz. woodland, scattered trees and scrub. Areas most suitable for sett construction were located around the edges. The extensive area of on-site grassland provided optimum foraging habitat. A preliminary search did not find any signs of badger, but this does not guarantee their absence as they are a mobile species. Badger records are not provided as part of the SxBRC data search. HIGH. Grassland and scrub mosaics provide habitat for widespread reptile species, but this is generally restricted to the edges. This Sub-area is located in a rural landscape and is connected to suitable off-site habitat to the south-east, south and southwest (including gardens along the southern boundary). There are off-site records for all four species of widespread reptile from the data search, the closest being a 1997 grass snake record 670m to the south of Subarea 2. An anecdotal record (from local land owner/resident) for grass snake was provided. Boundary vegetation including scattered trees and scrub provides potential hibernating habitat. Interface between grassland and scrub provides basking and foraging opportunities for widespread species of reptile. The pond, marshy grassland and spring provide habitat of potential value to The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1129 Table 5: Assessment of potential presence of invasive and protected species within Sub-area 2 of SDA 11 Species Main legislation (see Chapter 16) Great crested newt Wildlife and Countryside Act 1981 (as amended) Schedule 5.

Invasive plants species Section 14 and Part II of Schedule 9 of the Wildlife and Countryside Act 1981 (as amended) Reason for consideration grass snakes. The Sub-area includes a pond. Suitable terrestrial habitat is also present around the Sub-area boundary. Two ponds identified within a 500m radius, which is the guideline distance (English Nature, 2001) which great crested newt may commute between breeding ponds and terrestrial sites. The Sub-area is located in a rural setting on the north-west edge of Heathfield. The Sussex countryside has an abundance of shallow ponds suitable as breeding sites. Linear boundary features viz. woodland edge, and trees/scrub provide suitable nesting habitat. Food and nesting building plants were present. There is a wide range of invasive plant species of which a number of widespread species occur in woodlands, aquatic and wetland habitats, and disturbed sites or close to settlements. As such there is potential for invasive plants to be present in the Sub-area. Likelihood of occurrence MEDIUM. A recently recreated pond is located within the Sub-area. Suitable terrestrial habitat is present, although this is restricted to boundary edges viz. north and east. The pond has been recently created, had only small amounts of floating aquatic and emergent vegetation and therefore suitable egg-laying plants were very limited. Marshy grassland may occasionally provide temporary standing water, but for limited periods of the year. A mallard was using the pond and may predate any young amphibians present. There are no records within 500m of the Sub-area the closest being a 2006 record at Waldron Ghyll, 1.4km south of Sub-area 2. A single pond within 500m is visible on OS mapping, at Markly Wood to the north-west. There are no barriers to dispersal, but the presence of abundant habitat around these ponds may limit the need for animals to disperse to the Sub-area. MEDIUM. Potentially suitable habitat is limited to woodland edge along the northern boundary and peripheral areas of scattered trees and scrub. Whilst their structure is sub-optimal with a limited shrub layer they are contiguous with the large woodland complex to the north. Foraging and nest building plants such as honeysuckle, bramble and grey willow are present, but in low quantities. Hazel was absent. A 1998 data record was returned from Cross in Hand (Sellyns Farm) 1.6km west of Sub-area 2. PRESENT. Montbretia was recorded along the southern boundary with adjacent gardens. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1130 NATURE CONSERVATION EVALUATION: SUB-AREA 2 - LAND AT TILSMORE NURSERIES 13.109 On the basis of the information available from the Phase 1 habitat survey, data search and review of BAPs, Sub-area 2 has been evaluated in terms of its potential for biodiversity, support of protected species and habitats, and the contribution the area makes as part of the wider landscape. A combined evaluation of the nature conservation value of the Sub-area using standard criteria developed by IEEM (2006) and selected criteria from Defra's (2006) 'Local Sites' evaluation guidance is provided in Table 6 below. 13.110 The biodiversity value of protected and BAP species within the Sub-area is a preliminary evaluation based upon the desk study records, habitat suitability and the conservation status of the species in question. It should be noted that where European Protected Species or BAP species are present on-site they may be valued at a lower level/scale where it is considered likely that populations would not be of sufficient importance to justify designation at a higher level. However, regardless of their biodiversity value, such species are still subject to national and/or European legislation. 13.111 Key aspects of relevant planning policy and legislation regarding conservation, including an explanation of species referred to as being of 'Principal Importance for the Conservation of Biodiversity', European Protected Species and BAP species and habitats, are provided in Chapters 16-18. Table 6: Combined Evaluation of the Nature Conservation Value of Sub-area 2 of SDA 11. Criteria 7 Remarks Features of International Importance Sub-area 1 is not subject to any international statutory nature conservation designations. The closest site of International Importance is Ashdown Forest designated as both a SAC and SPA, located approximately 11.5km to the north-west. Ashdown Forest is important for its lowland wet and dry heath habitats and associated bird assemblage. No heathland habitat or any supporting habitats that maintain the integrity of this designated area are present within the SDA. Features of National Importance Sub-area 1 is not subject to any national nature conservation designations. It is not considered that any habitats or populations or assemblages of species within the Sub-area would meet the criteria for the designation of 7 SSSIs at an appropriate geographic level . Guidelines for selection of biological SSSIs http://jncc.defra.gov.uk/page-2303#download The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1131 Features of Regional (Sussex) Value Sub-area 2 is not subject to any non-statutory nature conservation designations. The northern boundary comprises scattered trees which have a remnant ancient woodland ground flora and are likely to have been modified from adjacent woodland which is the head/source of a ghyll flowing north into Markly Wood PAW. The Weald area of south-east England contains a concentration of ghyll woodland which is included under the county’s Woodland BAP and considered significant at this level. Features of District (Wealden) Importance Unimproved mildly acid/neutral grassland with a damp hollow of marshy grassland is present. Whilst this grassland resource does not fall within the category of lowland meadow or dry acid grassland (Sussex and UK BAP priority habitats) it is nonetheless an uncommon and declining habitat and is considered to be of ecological value of at least the district level. The grassland resource, in conjunction with scattered tree and scrub edge habitats is likely to support a moderately diverse assemblage of invertebrates of value at least at the district level. Features of Local (Heathfield) Importance A number of protected and UK BAP species may occur at the Sub-area, as follows: - Reptiles, including slow-worm, common lizard, grass snake and adder; - Birds such as house sparrow, cuckoo, starling, dunnock, linnet, song thrush and bullfinch; - Amphibians such as great crested newt and toads; - Invertebrates such as stag beetle: - Small mammals such as hedgehog and dormice; and - Bats, such as soprano, noctule bat and brown long eared. Based on the quality and extent of habitat present, it is considered that populations of these species would be significant at the local level. UK BAP priority habitat present on-site includes standing water (pond) although this has only been recently created, is yet to fully establish, is not considered to be an outstanding example of its type and is therefore considered to be of no more than local importance. Those parts of the SDA that are not heavily managed and/or publicly accessible such as woodland edge and scattered trees and scrub around the periphery (in conjunction with adjacent gardens) provide cover and foraging opportunities for a breeding bird assemblage of value in a local context. Features of Value within the immediate vicinity of the Sub-area The remaining habitats at the Sub-area comprising scrub, scattered trees and bracken are likely to be of some value as foraging, cover and breeding sites for a range of generalist species and therefore of value in maintaining the ecology of the area. However, they are common and widespread habitats that do not generally support rare species or diverse assemblages of species and are therefore of value in the immediate vicinity of the Sub-area. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1132 Features of Secondary and Supporting Value / Connectivity within the landscape Woodland edge and scattered tree and scrub habitats along the west, north and eastern boundary, may provide connectivity between off-site ecological receptors such as small fields, woodland, hedgerows and tree lines. Woodland edge and scattered trees and scrub habitats along the northern boundary may provide a buffer to both PAW in Markly Wood and ghyll woodland feeding into it. The Sub-area may extend the foraging and breeding range for off-site species using the adjacent woodland complex. The Sub-area may also function as a buffer to the urban edge of Heathfield and provides a wildlife corridor and/or stepping stones for mobile species moving across the Heathfield urban-rural fringe. Social Value / Recorded History and Cultural Associations This Sub-area is privately owned and accessed by a track off Nursery Way. It is jointly owned and managed by local residents. The primary value of Sub-area 2 is in its amenity and aesthetic value to residents whose houses back onto the Sub-area, affording them views over the countryside and recreation. No trees receiving TPOs are present on-site, but TPOs are present in residential properties adjacent to the southern boundary. Economic value Grassland is likely to have been historically grazed, but is currently managed by mechanical cutting. Habitats and species do not currently provide a resource that could be exploited for their economic value. The Sub-area measures 1.45ha (total SDA area 9.33ha) with woodland edge, scattered tree and scrub habitats occupying approximately 25% of the Sub-area. Grassland occupies the remaining 75%. Size and extent Due to the dominance of grassland the Sub-area supports only a moderate range of habitat types, but these have potential to support a wide range of protected and BAP species due to their type and geographic location. Protected species interest is strongly associated with peripheral habitats that offer both foraging and cover. The grassland may support notable invertebrates. Fragility The woodland edge and mature trees are susceptible to ground disturbance. The pond is susceptible to disturbance, pollution and changes in hydrology/drainage. The grassland (acid/neutral and marshy) is susceptible to both disturbance and changes in hydrology/drainage which would affect its species composition. It is also susceptible to scrub encroachment and the spread of coarse/rank grassland. The spring and pond are susceptible to changes in hydrology/drainage. Remaining habitats i.e. the bracken, young/semi-mature scattered trees and scrub and marginal vegetation are relatively recently established, would rapidly recover from impacts and can be restored. Typicalness Scattered tree and scrub habitats are typical of their individual types and are not outstanding examples. The pond and marginal vegetation are typical examples of newly created/establishing standing water habitats. An area of remnant ancient woodland ground flora to the north indicates that scattered trees in this area may be modified woodland. The grassland resource is typical of lightly acidic Wealden substrates in both dry and localised wet areas. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1133 Summary of Nature Conservation Evaluation 13.112 On the basis of the above criteria, Sub-area 2 is considered to be of ecological value within at least the Wealden District context due to the presence of wet and dry acid grassland. The Sub-area also appears to form part of the catchment of a ghyll stream flowing into Markly Wood. Due to the restricted distribution of such features in South East England, the Sub-area is considered to be of regional importance in terms of maintaining the hydrology of the stream, and boundary habitat would be important in buffering it from the effects of any future development. 13.113 Other habitats at the Sub-area, principally scrub, scattered trees and bracken are considered to be of value in the immediate vicinity of the Sub-area, as they provide habitat structure for a range of species. The Sub-area as a whole and particularly scrub and woodland at the boundaries provide buffering and supporting habitat to Markly Wood PAW. Due to its proximity to woodland and nature of the habitats present the Sub-area has potential to support a range of declining and BAP species, including those protected at National and European level i.e. breeding birds, badger, reptiles, great crested newts, bats and dormice. The legal and policy implications associated with these species are detailed in Chapter 16 and 17. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1134 GREEN INFRASTRUCTURE APPRAISAL: SUB-AREA 2 - LAND AT TILSMORE NURSERIES Water bodies and the local catchment area 13.114 Ghyll woodland runs parallel with the northern boundary of Sub-area 2. Areas of standing water include the newly created pond in the north-eastern corner. Both the central area of marshy grassland and the spring/channel along the eastern boundary feed into this pond, which in turn feeds into the adjacent ghyll woodland. Habitat connectivity 13.115 Markly Wood encapsulates all but the southern boundary of Sub-area 2 and consequently it is well connected to the larger woodland complex located to the north and west of Heathfield, via ghyll woodland, broad-leaved semi-natural woodland and scattered trees and scrub. These habitats provide a potential wildlife corridor for a range of mobile species such as bats, birds, invertebrates, badgers and small mammals. These species are potentially commuting along the woodland edge, within the Sub-area and moving across the Heathfield urban-rural fringe into the wider Wealden countryside and Heathfield Habitat Link BOA. Sustainable transport routes/PROW 13.116 Sub-area 2 is privately owned and no Public Right Of Way (PROW) is present. There is currently no network of cycle routes serving the Sub-area. The Sub-area can currently be accessed from Nursery Way via the A265. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1135 CONCLUSIONS AND RECOMMENDATIONS: SUB-AREA 2 - LAND AT TILSMORE NURSERIES 13.117 The Sub-area falls within the boundaries of the statutory designated High Weald AONB, but is not subject to any statutory or non-statutory nature conservation designations. The nearest statutory designated site for nature conservation is Heathfield Park SSSI located 1.7km to the east of Sub-area 2. The nearest non-statutory designated nature conservation site is Oaken & Furlong Woods SNCI located 2km to the north-east of Subarea 2. On the basis of information available at the time of report production, it is considered unlikely that the Sub-area performs an important supporting role for these sites based upon the type and extent of habitats present within the Sub-area, the features for which the sites are designated and the degree of connectivity between them. 13.118 Overall, Sub-area 2 is considered to be of ecological value within at least a district context, due to its potential to support a wide range of protected and BAP species. This potentially includes species protected at a National and European level i.e. badgers, reptiles, great crested newts, bats and dormice. This interest is strongly associated with woodland edge and scattered tree/scrub habitats around the periphery of the Sub-area that are connected to the larger woodland complex positioned to the north-east, north and north-west. 13.119 It is also considered to be of district value due to its grassland resource which occupies approximately 75% of the area and comprises mildly acid/neutral grassland with a small area of marshy grassland. These habitats were botanically diverse and (in conjunction with standing water and tree/scrub habitat present on-site) are likely to support a moderately diverse assemblage of invertebrates. 13.120 The Sub-area also provides an important secondary and supporting role to the network of ecological receptors surrounding it, primarily by: Buffering off-site areas of Markly Wood which includes an adjacent area of planted ancient woodland and the adjacent source/head of a ghyll woodland; and Providing wildlife corridors for species moving between the urban areas of Heathfield and the wider Wealden countryside. 13.121 Much of the Sub-area’s current ecological value can be attributed to its geographic (rural) location, the relatively undisturbed nature of its on-site habitats and active management from its owners. 13.122 The following UK BAP habitats/species are or have potential to be present within Subarea 2: The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1136 Reptiles, including slow-worm, common lizard, grass snake and adder; Birds such as house sparrow, cuckoo, starling, dunnock, linnet, song thrush and bullfinch; Amphibians such as great crested newt and common toad; Invertebrates such as stag beetle; Small mammals such as hedgehog and dormice; Bats, such as soprano pipistrelle, noctule bat and brown long eared; and Pond 13.123 BAP habitats/species are not necessarily rare but under PPS9 and the NERC Act 2006 are all of principal importance for biodiversity (ODPM, 2005) and are of material consideration in the planning process. None of the BAP habitats or populations of BAP species currently known to be present at the Sub-area are considered as notable or exceptional examples of their type. Recommended further surveys relevant to Sub-area 2 Overview 13.124 The surveys recommended below assume the loss of or damage to suitable habitat should the Sub-area be proposed for development. There is potential to avoid and/or limit impacts through habitat retention and protection (see below). The final approach to surveys will have to be based on consideration of detailed proposals for the Subarea/SDA, though in all cases published best practice should be followed with regard to survey methodology etc. 13.125 To provide a sufficient baseline of data and mitigate against any potential impact on declining, BAP and protected species/habitats at Sub-area 2, further surveys for reptiles, bats, badger, dormice, great crested newts, invertebrates, ghyll flora and invasive plants are recommended. Reptiles 13.126 The Sub-area includes the habitat mosaic and vegetation structure suitable for a number of widespread reptile species, including both grass snakes and for adders. There are open areas for basking, cover against predation as well as numerous potential hibernation spots. There are foraging opportunities for adders within the unimproved grassland, a habitat that often has a higher density of small mammals. The head/source of the ghyll to the east may also provide suitable foraging for grass snakes. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1137 13.127 A minimum of a seven visit reptile survey, following current guidelines (Froglife, 1999, English Nature 2004; Natural England 2011b), should be carried out to establish the presence/absence and distribution of reptiles. The grassland/scrub mosaic and edge habitats should be targeted. The optimum time is generally late spring, from April through June and in the early autumn in September. Where possible, survey effort should be spread across the recording season i.e. March-October. Bats 13.128 The habitats within the Sub-area are of high value for bats when judged against current assessment criteria (BCT, 2007). This is due to the strong connectivity with the wider landscape, presence of adjacent areas of ancient woodland, mature on-site trees suitable for roosting, good quality and diversity of foraging habitats (woodland and unimproved grassland) and proximity to known roosts. 13.129 Following current guidelines (BCT, 2007) further bat surveys are recommended to assess the presence or potential presence of any bat roosts, as well as the function the Sub-area might provide for foraging and commuting. These should include both tree inspections, and activity and emergence surveys. Emergence and activity surveys must be carried out between May and September. Badger 13.130 Although no setts were discovered during the Phase 1 survey the landscape of Sub-area 1 provides a highly suitable area for sett building and foraging. The potential for badgers is substantially increased due to the expanse of adjacent woodland and a good diversity of habitat types for foraging. 13.131 In order to assess the use of the Sub-area by badger a survey should be carried out in all areas of suitable on-site sett-building and foraging habitat to look for signs and evidence of this species. Survey effort should also include suitable off-site areas within a minimum 30m distance of the site boundary. This is in line with current Natural England recommendations and the possibility of sett disturbance caused by construction activities (Highways Agency, 2001; Natural England, 2007). 13.132 Holes attributed to badger should be classified as well used, partially used or disused in line with the methodology given in the National Badger Survey (Cresswell et al. 1990; Wilson et al. 1997). Setts should be classified as main, annexe, subsidiary and outlier (Wilson, Harris & McLaren, 1997). Surveys to identify setts should be carried out in the winter while surveys to establish the level of foraging and the likely impact of loss of foraging habitat and mitigation required should be conducted in the summer. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1138 Dormouse 13.133 The woodland and scattered trees and scrub form a continuous habitat layer and one that is contiguous with the surrounding woodland. Apart from during their hibernation phase, dormice are almost exclusively arboreal animals and require such interconnected habitats to forage and commute between sites. This species is particularly susceptible to impacts from habitat fragmentation and any loss or impact to scrub/trees/woodland across the Sub-area could have a significant negative impact. 13.134 Therefore, it is recommended that a survey for this species is carried out. This should be carried out using artificial nesting tubes (standard survey methodology). Surveys should follow best practice provided in English Nature’s Research Report 524: Surveying Dormice Using Nest Tubes (Chanin and Woods, 2003) and their Dormouse Conservation Handbook (2006). Surveys should be carried out between April and November. Great crested newts 13.135 Woodland edge, scattered trees, scrub and the grassland mosaic provides suitable terrestrial habitat for great crested newts. In addition, there is a pond within the sub-area and an additional pond, a series of ghylls, springs and wet flushes within a 500m radius of the Sub-area, which is the guideline distance (English Nature, 2001) that great crested newt may commute between breeding ponds. Therefore, it is recommended that a Habitat Suitability Index (HSI) survey, following Oldham et al (2000), is carried out on all ponds within a 500m radius of the Sub-area’s boundaries that do not have significant barriers to dispersal. 13.136 Using the results from the HSI, presence/absence surveys of ponds within 500m of the Sub-area that do not have any significant barriers to dispersal between them and the Sub-area may need to be carried out. Four presence/absence surveys should be carried out following best practice guidelines (English Nature, 2001) between mid-March and mid-June with at least two of these surveys between mid-April and mid-May. 13.137 The requirement for further survey will depend on the quality of the ponds as breeding habitat and the number and distance of suitable breeding ponds from the Sub-area. It is likely that the great majority of suitable on-site habitat around boundaries will be retained. However, surveys are still likely to be required to determine population size (if presence is confirmed), and the degree to which great crested newt are a constraint to any proposed development in terms of planning construction works and whether works will require a EPSM licence. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1139 Invertebrates 13.138 Sub-area 1 supports a moderate diversity of habitat types, including those of high value to invertebrates, i.e. unimproved and marshy grassland, woodland, mature oak trees and edge/mosaic habitats. If these habitats are to be affected by development a terrestrial invertebrate survey is recommended. Survey effort should focus on woodland edge and grassland habitats and include a selection of survey methods to assess the range of invertebrate fauna likely to be present on-site. Therefore, surveys may be required to inform impact assessments, establish an acceptable extent of development or to inform mitigation proposals. Lower plants 13.139 A ghyll is adjacent to the northern boundary of the Sub-area. Ghyll woodland is a Sussex BAP priority habitat and known to support important disjunct populations of ‘oceanic’ vascular plant and bryophyte species. Ghylls are very susceptible to changes in microclimate, hydrogeology and physical disturbance. Potential impacts from development that may cause these changes are alterations to the local surface and ground water flow, removal of woodland cover in proximity to the ghyll and erosion and compaction from increased recreation. Surveys may therefore be required to inform impact assessments, establish an acceptable extent of development or to inform masterplanning and mitigation proposals. 13.140 The survey should be carried out along all sections adjacent to Sub-area 2 and up to 100m downslope. This is to determine the distribution and composition of the ghyll flora, the potential presence of uncommon, rare and protected pteridophtye (fern) and bryophytes (mosses and liverworts) species. Invasive plant species 13.141 Montbretia was present on site and is an invasive plant species included on Schedule 9 of the Wildlife and Countryside Act 1981 (as amended) under which it is an offence to plant or otherwise cause these species to grow in the wild. It is possible that it could be spread during construction works and, therefore, a survey to accurately determine its extent, and to inform a method statement to avoid spread, will be required. Outline mitigation relevant to Sub-area 2 Habitat retention and protection 13.142 Unimproved mildly acid/neutral grassland with a central area of marshy grassland is the most ecologically important habitat present within the Sub-area and any development proposal should seek to retain it. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1140 13.143 Scattered trees and scrub along the northern boundary provide a buffer to the adjacent ghyll woodland (which is a UK and Sussex BAP priority habitat) and development proposals should seek to retain these habitats. 13.144 Where the loss of the scattered trees, scrub and/or grassland, described above, is unavoidable it will be necessary to carry out any required protected species surveys and mitigation prior to their removal and provide compensation for their loss. 13.145 All construction works taking place in the vicinity of adjacent woodland, retained scattered trees, scrub and grassland should conform to British Standard 5837:2005 Trees in Relation to Construction. 13.146 Markly Wood PAW is adjacent to the northern corner of the Sub-area. Following Natural England’s Standing Advice on Ancient Woodland (2011a) a minimum buffer of at least 15m in width should be maintained between ancient woodland and any development boundary. Subject to the results of any further ecological surveys and liaison with relevant statutory bodies it may be necessary to increase the width of the buffer zone. 13.147 Drainage channels in close proximity to springs/flushes, feeding streams and/or ghylls should be managed to avoid changes to surface and ground water levels, any discharge of pollution or sediments and the diversion of water away from these habitats. All works near water courses and wetland features should adhere to best practice guidance to avoid adverse effects upon water quality, such as Pollution Prevention Guidance 5: Works and maintenance in or near water (Environment Agency, 2007). In addition, zones alongside ghyll woodland should remain undisturbed by creating buffer areas. Mitigation for protected species 13.148 Nesting birds: Woodland edge, scattered trees and dense scrub provide suitable nesting habitat for a variety of bird species. It is recommended that any vegetation clearance affecting nesting habitat should be undertaken outside of the bird nesting season which runs from March to August inclusive. 13.149 Bats and lighting: While different species of bat react differently to night time lighting, research has found that bats are sensitive to artificial lighting and that excessive lighting can delay bats from emerging, thus shortening the time available for foraging, as well as causing bats to move away from suitable foraging grounds or roost sites, to alternative dark areas (Jones, 2000). 13.150 Currently the whole Sub-area remains dark at night and to minimise impacts on bats from lighting associated with any proposed development it will be necessary to limit light The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1141 spillage and glare, particularly along woodland edge. This can be achieved by following accepted best practice (Institute of Ecology and Environmental Management 2006, Institute of Lighting Engineers 2007): Habitat compensation relevant to Sub-area 2 13.151 Any compensation planting should draw on best practice with regard to the use of native species of local provenance, avoidance of invasive species, and use of non-native species of known wildlife value provided in Chapter 19. Initial measures to be considered in development proposals for Sub-area 2 would be as follows: Replacement planting to compensate for any loss of woodland, trees, scrub, hedgerows etc. should be provided as an integral part of any landscape masterplanning for Sub-area 2/SDA 11. It should include only native species. If development involves the removal of semi-mature trees with potential to provide habitat for birds and bat in the future then there would be a particular value in using artificial bird and bat boxes to provide replacement nesting/roosting habitat. Habitat enhancement relevant to Sub-area 2 13.152 The following outline proposals for habitat enhancement should be considered as part of detailed proposals for development of Sub-area 1 to ensure that features of local ecological value contribute to the ecology of the District as a whole. Additional generic management recommendations for these features are provided in Chapter 19. Grassland 13.153 The grassland is currently managed by one annual cut in July/August, with arisings removed. In the absence of grazing this is an appropriate technique to ensure the ecological value of the grassland in the long-term. Where resources permit, it would be beneficial to carry out a second cut either in late autumn (or later if conditions are suitable). This will remove any secondary/late season re-growth and reduce the build-up of thatch and nutrients which will reduce the botanical diversity of the grassland. Care should always be taken when cutting the area of marshy grassland to avoid compaction and/or erosion. Self-established saplings should be removed and the scrub edge (along the spring/north-east edge) cut back on a cyclical basis. The spread of bracken in this location should also be monitored as it may be necessary to manage dense stands by pulling/cutting/chemical treatment etc. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1142 Green infrastructure enhancements relevant to Sub-area 2 13.154 The Sub-area is partly within Heathfield Habitat Link BOA and any development proposals should consider the BOA targets which seek to sympathetically manage the habitat mosaic present in the area and increasing the ‘permeability’ of the landscape for wildlife. 13.155 Many of the recommendations for habitat protection, creation and enhancement are likely to benefit both biodiversity and green infrastructure within the District. In order to ensure these issues are adequately addressed at the Sub-area level, specific recommendations referring to issues such as off-site habitat, hydrology, access and landscape are provided below: Scrub and woodland around the boundaries should be largely retained to buffer the adjacent PAW and retain corridors of woodland along the northern edge of Heathfield. Any additional planting should be positioned so as to enhance green corridors on-site. Native tree and shrub species should be typical of the local landscape (High Weald AONB). From a green infrastructure perspective, the retention of springs and marshy grassland will ensure that the natural drainage system for the Sub-area continues to function. Where marshy grassland is to be retained and incorporated within development proposals, it should form part of the wider SuDS for the Subarea/SDA. Detailed hydrological studies should be carried out to ensure that development does not adversely affect water supply or water quality within the adjacent ghyll stream. SuDS and other pollution control measures may be required to ensure that adverse effects do not occur. If any proposed development comprises large areas of buildings and hardstanding the use of SuDs schemes, green roofs and walls should be considered to enhance the biodiversity value of the Sub-area, protect water quality and reduce the rate of runoff. The use of native tree and shrub planting and species of known wildlife value in landscape schemes should be considered in detailed landscape proposals as this will provide opportunities for wildlife at the smallest scale of development, ensuring that opportunities for common species are not diminished. 13.156 Further detail on measures to enhance biodiversity and green infrastructure are provided in Chapter 19. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1143 HABITAT SURVEY: SUB-AREA 3 - LAND TO THE REAR OF ROTHERSHAW Overview 13.157 All parts of Sub-area 3 were surveyed on the 24th May 2011. The Sub-area is 1.15ha in size and occupies land to the rear of Rothershaw. The Sub-area borders both Sub-area 2 (west) and Sub-area 4 (east). The southern boundary includes the garden and wider grounds of the house known as ‘Rothershaw’. The northern part of the Sub-area includes part of Markly Wood Planted Ancient Woodland. Habitats present within the Sub-area included; unimproved acid, semi-improved acid and marshy grassland, mixed woodland, scattered trees and scattered scrub. Mixed woodland 13.158 An area of Planted Ancient Woodland was noted in the north of the Sub-area with eastern hemlock and Norway spruce. However, this stock was over-mature and a native acid woodland flora was re-establishing, dominated by pedunculate oak with birch and a shrub layer of holly and mountain ash. Bird cherry was noted as a single tree. Bracken dominated the herb layer, but hybrid bluebell was abundant, alongside enchanter’s nightshade, honeysuckle and common dog violet. A clearing in the plantation supported abundant lady fern, remote sedge and hybrid cinquefoil. Scattered trees and scrub 13.159 Abundant pedunculate oak, frequent downy birch and occasional holly marked the eastern boundary with Sub-area 4. Ghyll (off-site) 13.160 The northern boundary of Sub-area 3 was marked by a ghyll (see also description of ghyll in Sub-area 2) with a wide marginal zone of deep, damp sediment supporting abundant sedges (remote sedge, pendulous sedge, pale sedge) and lady fern. The banks appeared to be of bryological interest. Semi-improved acid grassland 13.161 Open area of grassland both to the south of the woodland and within the mixed woodland to the north comprised abundant sweet vernal-grass and frequent smooth meadow grass, Yorkshire fog, creeping buttercup, oval sedge and silverweed. Tussocks of soft rush, and associated herbs including common dog violet and hybrid cinquefoil were also present. Marshy grassland 13.162 Acid flushes were present within the areas of on-site semi-improved grassland. They supported jointed rush, pink water speedwell and greater bird’s-foot-trefoil in the south The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1144 with more abundant soft rush, lady fern, smooth-stalked sedge and tufted hair-grass to the north, although this area was beginning to scrub over with grey willow. Fauna 13.163 The following bird species were recorded during the survey of Sub-area 3; great tit, chiffchaff, blue-tit and wood pigeon. Target Notes target notes relevant to Sub-area 3 13.164 Target Notes (T) are features within the Sub-area assessed as being of ecological interest and are marked on the Habitat Map in Appendix.

The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1145 PROTECTED SPECIES RISK ASSESSMENT: SUB-AREA 3 - LAND TO THE REAR OF ROTHERSHAW 13.166 The habitats at Sub-area 3 were evaluated as to their likelihood to provide sheltering, roosting, nesting and foraging habitat for the following species/species groups: Breeding birds Bats Badgers Reptiles Great crested newt Dormice Invasive plant species 13.167 These species were selected for further consideration because the results of the desk study revealed that they occur in the vicinity of SDA 11 and potentially suitable habitat is present within Sub-area 3. The results of the field survey, combined with information from the desk study, are presented in Table 7 below. The relevant legislation and policies relating to protected species is presented within Chapter 16 and 17. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1146 Table 7: Assessment of potential presence of invasive and protected species within Sub-area 3 of SDA 11 Species Main legislation (see Chapter 16) Reason for consideration Likelihood of occurrence HIGH. Areas of suitable breeding habitat for a variety of species viz. mixed woodland (PAW), scattered trees and scrub are present in the northern half of Sub-area 3 and along its western and eastern boundary. This provides suitable nest sites for a variety of bird species. The Sub-area is well connected to off-site foraging resources in the wider countryside, particularly Markly Wood to the north. 65 species recorded within a 2km radius of the SDA. LOW (roosting) HIGH (foraging). Extensive areas of connected woodland (including PAW and ghyll woodland) stretch to the west and north providing both suitable roosting, and foraging opportunities. Semi-improved grassland provides supplementary foraging habitat, but is limited in extent. No buildings were present on-site and mature non-native trees in the mixed woodland provided limited roosting opportunity. Seven bat species are recorded within a 2km radius of the SDA including a Natterer’s hibernation roost approximately 250m east of Sub-area 3. MEDIUM. The Sub-area and adjacent habitat included good cover and connectivity for badger to move across the wider landscape viz. mixed woodland, scattered trees and scrub. Areas most suitable for sett construction were located to the north (woodland) and around the western and eastern boundary. On-site grassland provided good foraging habitat. A preliminary search of the Sub-area did not find any signs of badger, but this does not guarantee their absence as they are a mobile species. Badger records are not provided as part of the SxBRC data search. HIGH. Grassland and scrub mosaics provide habitat for widespread reptile species, but this is generally restricted to the southern half of the Sub-area and open areas within the mixed woodland. The Sub-area is located in a rural area and connected to suitable off-site habitat to the east (Sub-area 4), south (grounds of Rothershaw) and west (Sub-area 2). Breeding birds Wildlife and Countryside Act 1981 (as amended) selected species Schedules 1 and 8. Mixed woodland, scattered trees and scrub, provide suitable breeding habitat for both common garden species and woodland species. Open countryside to the east, north and west and gardens to the south provide a wider foraging network. Bats Wildlife and Countryside Act 1981 (as amended) Schedule 5. The Conservation of Habitats and Species Regulations 2010 - Schedule 2. Adjacent woodland complex provides extensive off-site foraging, commuting and roosting habitat. On-site grassland provides foraging habitat. The Sub-area is located on the north-western edge of Heathfield with excellent connectivity with open countryside to the west, north and east. Badger Protection of Badgers Act 1992. Widespread and wide-ranging species, especially in the south and west of the UK. Mixed woodland, scattered tree and scrub habitat is suitable for sett-building.

Invasive plants species Section 14 and Part II of Schedule 9 of the Wildlife and Countryside Act 1981 (as amended) Reason for consideration Likelihood of occurrence adjacent pond and ghyll woodland provides habitat of potential value to grass snakes. There are off-site records for all four species of widespread reptile from the data search, the closest being a 1997 grass snake record approximately 620m to the south of Sub-area 3. HIGH. The adjacent pond is currently considered suboptimal as it is newly created. Suitable terrestrial habitat is present viz. mixed woodland and boundary edges. Marshy grassland may occasionally provide temporary standing water, but for limited periods of the year. There are no records within 500m of the Sub-area the closest being a 2006 record at Waldron Ghyll, 1.5km south of Sub-area 3. A single pond within 500m is visible on OS mapping, at Markly Wood to the north-west. There are no barriers to dispersal, but the presence of abundant habitat around these ponds may limit the need for animals to disperse to the Sub-area. A pond is located adjacent in Sub-area 2. Suitable terrestrial habitat is present around the Sub-area boundary and within mixed woodland. One other pond is present within a 500m radius, which is the guideline distance (English Nature, 2001) which great crested newt may commute between breeding ponds and terrestrial sites. The Sub-area is located in a rural setting on the north-western edge of Heathfield. The Sussex countryside has an abundance of shallow ponds suitable as breeding sites. Mixed woodland and trees/scrub provide suitable nesting habitat. Food and nesting building plants were present. There is a wide range of invasive plant species of which a number of widespread species occur in woodlands, aquatic and wetland habitats, and disturbed sites or close to settlements. As such there is potential for invasive plants to be present in the Sub-area. MEDIUM. Potentially suitable on-site habitat is limited to the northern half of the Sub-area and along the western and eastern boundary. Suitable food and nest building plants such as hazel, bramble and honeysuckle were limited. Whilst the structure and type of on-site woodland is sub-optimal the Sub-area is connected to extensive areas of off-site woodland and dormice have been recorded as using PAW. A 1998 data record was returned from Cross in Hand (Sellyns Farm) 1km west of Sub-area 3. LOW. No evidence of invasive plant species was recorded on-site during the Phase 1 habitat survey though this does not guarantee their absence. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1148 NATURE CONSERVATION EVALUATION: SUB-AREA 3 - LAND TO THE REAR OF ROTHERSHAW 13.168 On the basis of the information available from the Phase 1 habitat survey, data search and review of BAPs, Sub-area 3 has been evaluated in terms of its potential for biodiversity, support of protected species and habitats, and the contribution the area makes as part of the wider landscape. A combined evaluation of the nature conservation value of the Sub-area using standard criteria developed by IEEM (2006) and selected criteria from Defra's (2006) 'Local Sites' evaluation guidance is provided in Table 8 below. 13.169 The biodiversity value of protected and BAP species within the Sub-area is a preliminary evaluation based upon the desk study records, habitat suitability and the conservation status of the species in question. It should be noted that where European Protected Species or BAP species are present on-site they may be valued at a lower level/scale where it is considered likely that populations would not be of sufficient importance to justify designation at a higher level. However, regardless of their biodiversity value, such species are still subject to national and/or European legislation. 13.170 Key aspects of relevant planning policy and legislation regarding conservation, including an explanation of species referred to as being of 'Principal Importance for the Conservation of Biodiversity', European Protected Species and BAP species and habitats, are provided in Chapters 16-18. Table 8: Combined Evaluation of Nature Conservation Value of Sub-area 3 of SDA 11. Criteria 8 Remarks Features of International Importance Sub-area 3 is not subject to any international statutory nature conservation designations. The closest site of International Importance is Ashdown Forest designated as both a SAC and SPA, located approximately 11.5km to the north-west. Ashdown Forest is important for its lowland wet and dry heath habitats and associated bird assemblage. No heathland habitat or any supporting habitats that maintain the integrity of this designated area are present. Features of National Importance Sub-area 3 is not subject to any national nature conservation designations. It is not considered that any habitats or populations or assemblages of species within the Sub-area would meet the criteria for the designation of 8 SSSIs at an appropriate geographic level . Features of Regional (Sussex) Value Sub-area 3 is not subject to any non-statutory nature conservation designations. The northern half of the Sub-area boundary comprises ghyll and PAW. The Weald area of South-East England contains a concentration of ghyll woodland which is included under the county’s Woodland BAP and JNCC Guidelines for selection of biological SSSIs (see http://jncc.defra.gov.uk/page-2303#download). The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1149 Table 8: Combined Evaluation of Nature Conservation Value of Sub-area 3 of SDA 11. Criteria Remarks significant at this level. Sub-area 3 has potential to support the following Sussex BAP priority species; song thrush, barn owl, common toad, soprano pipistrelle, common pipistrelle, stag beetle and great crested newt. While populations of BAP species may be present, it is not considered that any would be regionally important examples of their type. Features of District (Wealden) Importance Areas of unimproved and semi-improved mildly acid grassland with flushes dominated by marshy grassland are present on-site. Whilst this grassland resource is small in extent and does not fall within the category of lowland meadow or dry acid grassland (Sussex and UK BAP priority habitats) it is nonetheless an uncommon and declining habitat and is considered to be of ecological value at the district level. Features of Local (Heathfield) Importance A number of protected and UK BAP species may occur at the Sub-area, as follows: - Reptiles, including slow-worm, common lizard, grass snake and adder; - Birds such as house sparrow, starling, dunnock and song thrush; - Amphibians such as great crested newt and toads; - Invertebrates such as stag beetle and grizzled skipper (recorded at the Sub-area); - Small mammals such as hedgehog and dormice; and - Bats, such as soprano, noctule bat and brown long eared. Based on the quality and extent of habitat present, it is considered that populations of these species would be significant at the local level. Woodland and scattered trees and scrub habitats around the periphery of the Sub-area provide cover and foraging opportunities for a breeding bird assemblage of value in a local context, due to its potential diversity and not the presence of BAP species (features of regional/national importance). Features of Value within the Zone of Influence of the Project The remaining habitats at the Sub-area comprising scattered trees and scrub, marginal vegetation etc. are likely to be of some value as foraging, cover and breeding sites for a range of generalist species and therefore of value in maintaining the ecology of the area. However, they are common and widespread habitats that do not generally support rare species or diverse assemblages of species and are therefore of value in the immediate vicinity of the Sub-area. Features of Secondary and Supporting Value / Connectivity within the landscape Mixed woodland, and scattered tree and scrub habitats along the western and eastern boundary may provide connectivity between off-site ecological receptors such as small fields, woodland units, hedgerows and tree lines (see above). Mixed woodland in the north of the Sub-area may provide a buffer to both PAW and ghyll woodland within Markly Wood. The Sub-area may extend the foraging and breeding range for off-site species using the adjacent woodland complex. The Sub-area may also function as a buffer to the urban edge of Heathfield and provides a wildlife corridor and/or stepping stones for mobile species moving across the Heathfield urban-rural fringe. Social Value / Recorded History and Cultural Associations The Sub-area is privately owned and accessed only through the grounds of Rothershaw or via Sub-area 4. The primary value of Sub-area 3 is in its amenity and aesthetic value to residents of Rothershaw whose houses back onto the Sub-area, affording them views over the countryside and potential (informal) recreation. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1150 Table 8: Combined Evaluation of Nature Conservation Value of Sub-area 3 of SDA 11. Criteria Remarks No trees receiving TPOs are present on-site or adjacent to its boundary. Economic value Grassland is likely to have been historically grazed, but is currently managed by mechanical cutting. Whilst it is generally recommended that mature oaks be retained, they could potentially be harvested for timber, but due to the small size of the mixed woodland and access restrictions this may not be an economically viable enterprise. All remaining habitats and species do not currently provide a resource that could be exploited for their economic value. Size and extent The Sub-area measures 1.15ha (total SDA area 9.33ha) with mixed woodland, scattered tree and scrub habitats occupying approximately 50% of the Sub-area. Grassland occupies the remaining half of the Subarea. Due to the small size of the Sub-area it supports only a moderate range of habitat types, but these have potential to support a wide range of common and protected species due to their type and geographic location. Protected species interest is strongly associated with the northern half of the Sub-area and boundary habitats that afford both foraging and cover for wildlife. Fragility The mixed woodland and mature trees are susceptible to ground disturbance. The unimproved and marshy sections of grassland are susceptible to disturbance, changes in hydrology/drainage, scrub encroachment and the spread of coarse/rank grassland which would affect its species composition. Whilst the areas of semi-improved acid grassland are susceptible to similar threats this habitat type has undergone some improvement already and is therefore less fragile. The ghyll woodland is susceptible to disturbance and changes in hydrology/drainage. Remaining habitats i.e. young/semi-mature scattered trees and scrub are relatively recently established, would rapidly recover from impacts and can be restored. Typicalness Mixed woodland is not typical of its type, as it includes an open central area with acid grassland/flush and the re-establishment of a native acid woodland flora indicates that it is recovering from habitat modification. Scattered trees and scrub are typical of their individual types. The grassland resource is typical of lightly acidic Wealden substrates with localised wet areas. Summary of Nature Conservation Evaluation 13.171 On the basis of the above criteria, Sub-area 3 is considered to be of ecological value within the district context due to the presence of wet and dry acid grassland. The Subarea also appears to form part of the catchment of a ghyll stream flowing into off-site areas of Markly Wood PAW. Due to the restricted distribution of such features in SouthEast England, the Sub-area is considered to be of regional importance in terms of maintaining the hydrology of the stream, and boundary habitat (including on-site PAW) would be important in buffering it from the effects of any future development. Due to the presence of PAW and the nature of the habitats present the Sub-area has potential to support a range of declining and BAP species, including those protected at a National The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1151 and European level i.e. badger, reptiles, great crested newts, bats and dormice. The legal and policy implications associated with these species are detailed in Chapter 16 and 17. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1152 GREEN INFRASTRUCTURE APPRAISAL: SUB-AREA 3 - LAND TO THE REAR OF ROTHERSHAW Water bodies and local catchment area 13.172 Ghyll woodland (part of Markly Wood PAW) is part of the northern limit of the Sub-area. An acid flush with marshy grassland runs along the western half of the Sub-area and is likely to feed into this ghyll. No standing water was present. Habitat connectivity 13.173 Markly Wood is contiguous with the northern boundary and consequently Sub-area 3 is well connected to the larger woodland complex located to the north and west of Heathfield, via on-site woodland and lines of scattered trees and scrub. The Sub-area is also well connected to Sub-areas 1 and 2 via shared boundaries of scattered trees and scrub. These habitats provide a potential wildlife corridor for a range of mobile species such as bats, birds, invertebrates, badgers and small mammals. These species are potentially commuting along the woodland edge, within the Sub-area and moving across the Heathfield urban-rural fringe into the wider Wealden countryside and Heathfield Habitat Link BOA. Sustainable transport routes/PROW 13.174 Sub-area 3 is privately owned and no Public Right Of Way (PROW) is present. There is currently no network of cycle routes serving the Sub-area. There are three private access points into the overall SDA from the A265, which serve Sub-areas 1, 2 and 4, but not Sub-area 3. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1153 CONCLUSIONS AND RECOMMENDATIONS: SUB-AREA 3 - LAND TO THE REAR OF ROTHERSHAW 13.175 The Sub-area falls within the boundaries of the statutory designated High Weald AONB, but is not subject to any statutory or non-statutory nature conservation designations. The nearest statutory designated site for nature conservation is Heathfield Park SSSI located 1.6km to the east of Sub-area 4. The nearest non-statutory designated nature conservation site is Oaken & Furlong Woods SNCI located 1.75km to the north-east of Sub-area 3. On the basis of information available at the time of report production, it is considered unlikely that the Sub-area performs an important supporting role for these sites based upon the habitats present, the features for which the sites are designated and the degree of connectivity between them. 13.176 Overall, Sub-area 3 is considered to be of ecological value within a district context, due to the presence of PAW and ghyll woodland, and the Sub-area’s potential to support a range of protected and BAP species. This potentially includes species protected at a National and European level i.e. badgers, reptiles, great crested newt, bats and dormice. This interest is strongly associated with mixed woodland in the northern half of the Subarea and scattered tree/scrub habitats along the western and eastern boundary that are connected to the larger woodland complex positioned to the east, north and west of the Sub-area. 13.177 Ecological interest is also attributed to the Sub-area’s grassland resource which occupies approximately 50% of the area and comprises unimproved and semi-improved mildly acid grassland with flushes of marshy grassland. These habitats had a moderate diversity of plant species and (in conjunction with mixed woodland and scattered tree and scrub habitat present on-site) are likely to support a moderately diverse assemblage of invertebrates. 13.178 The Sub-area also provides an important secondary and supporting role to the network of ecological receptors surrounding it, primarily by: Buffering Markly Wood PAW and ghyll woodland present in the northern half of the Sub-area. Providing wildlife corridors for species moving between the urban areas of Heathfield and the wider Wealden countryside. 13.179 Much of the Sub-area’s current ecological value can be attributed to its geographic (rural) location, and the relatively undisturbed nature of its on-site habitats. However, opportunities for enhancing the Sub-area for wildlife do exist, particularly in the northern half where the woodland is unmanaged. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1154 13.180 The following UK BAP habitats/species are or have potential to be present within the Sub-area: Lowland mixed deciduous woodland; Reptiles, including slow-worm, common lizard, grass snake and adder; Birds such as house sparrow, cuckoo, starling, dunnock, linnet, song thrush and bullfinch; Amphibians such as great crested newt and common toad; Invertebrates such as stag beetle Small mammals such as hedgehog and dormice; and Bats, such as soprano pipistrelle, noctule bat and brown long eared. 13.181 BAP habitats/species are not necessarily rare but under PPS9 and the NERC Act 2006 are all of principal importance for biodiversity (ODPM, 2005) and are of material consideration in the planning process. None of the BAP habitats or populations of BAP species currently known to be present at the Sub-area are considered as notable or exceptional examples of their type. Recommended further surveys relevant to Sub-area 3 Overview 13.182 The surveys recommended below assume the loss of or damage to suitable habitat should the Sub-area be proposed for development. There is potential to avoid and/or limit impacts through habitat retention and protection (see below). The final approach to surveys will have to be based on consideration of detailed proposals for the SDA/Subareas, though in all cases published best practice should be followed with regard to survey methodology etc. 13.183 To provide a sufficient baseline of data and mitigate against any potential impact on declining, BAP and protected species/habitats at Sub-area 3, further surveys for reptiles, bats, badger, dormice, great crested newts, invertebrates and ghyll flora are recommended. Reptiles 13.184 Open grassland areas in the southern section of Sub-area 3 provide good basking and cover opportunities for a variety of reptile species. The edge habitats here may also provide a function for hibernation within tree root systems etc. The grassland within the woodland clearing to the north may also be utilised, but any population here may be more The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1155 restricted in size due to shading from the tree line. The areas of ghyll and marshy grassland could be used as foraging by grass snakes. 13.185 A minimum of a seven survey visits, following current guidelines (Froglife, 1999, English Nature 2004; Natural England 2011b), should be carried out to establish the presence/absence and distribution of reptiles throughout the two areas of grassland and edge habitats. The grassland/scrub mosaic and edge habitats should be targeted. The optimum time is generally late spring, from April through to June and in the early autumn in September. Where possible, survey effort should be spread across the recording season i.e. March-October. Bats 13.186 There were only very limited resources available for roosting although the mixed woodland and the clearing within it could provide an important foraging resource for woodland specialist bats. The unimproved grassland area may also have a high invertebrate density and diversity and attract bats from the wider area, potentially from roosts within the woodland or houses to the south. 13.187 Following current guidelines (BCT, 2007) further bat surveys are recommended to assess the presence or potential presence of any bat roosts, as well as the function the Sub-area might provide for foraging and commuting. This should include both tree inspections and activity and emergence surveys. Emergence and activity surveys must be carried out between May and September. Badger 13.188 Although no evidence of sett building was found during the initial survey the block of mixed woodland and other edge habitats particularly along the ghyll could provide suitable cover and topography for such. The potential for badgers is increased due to the large area of foraging provided by grassland. Badgers are ubiquitous in rural and urban Sussex and may often be found along urban fringes. 13.189 In order to assess the use of the Sub-area by badger a survey should be carried out in all areas of suitable on-site sett-building and foraging habitat to look for evidence of this species. Survey effort should also include suitable off-site areas within a minimum 30m distance of the Sub-area boundary. This is in line with current Natural England recommendations and the possibility of sett disturbance caused by construction activities (Highways Agency, 2001; Natural England, 2007). 13.190 Holes attributed to badger should be classified as well used, partially used or disused in line with the methodology given in the National Badger Survey (Cresswell et al. 1990; The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1156 Wilson et al. 1997). Setts should be classified as main, annexe, subsidiary and outlier (Wilson, Harris & McLaren, 1997). Surveys to identify setts should be carried out in the winter while surveys to establish the level of foraging and the likely impact of loss of foraging habitat and mitigation required should be conducted in the summer. Dormouse 13.191 The parts of this Sub-area that are suitable for dormouse are limited to edge habitats to the east/west and the mixed woodland to the north. However, the value of these habitats for this species may primarily be from providing habitat connectivity to adjacent areas of higher value. Any loss or alteration to the main woodland block could have an impact through habitat fragmentation. It is recommended that the presence or otherwise of this species within the woodland and edge habitats is established prior to any works. 13.192 Therefore, it is recommended that a survey for this species is carried out. This should be carried out using artificial nesting tubes (standard survey methodology). Surveys should follow best practice provided in English Nature’s Research Report 524: Surveying Dormice Using Nest Tubes (Chanin and Woods, 2003) and their Dormouse Conservation Handbook (2006). Surveys should be carried out between April and November. Great crested newt 13.193 The adjacent pond and the local network of water bodies within a 500m radius of the Sub-area, the guideline distance that great crested newt may commute between breeding ponds (English Nature, 2001), provide potential breeding habitat. If present in off-site ponds then this species could certainly exploit the grassland areas for foraging and the mixed woodland for foraging and hibernation. 13.194 To assess the need or otherwise for more comprehensive pond surveys it is recommended that a HSI survey, following Oldham et al (2000), is carried out on all ponds within a 500m radius of the Sub-area’s boundaries that do not have significant barriers to dispersal. Four presence/absence surveys should be carried out following best practice guidelines (English Nature, 2001) between mid-March and mid-June with at least two of these surveys between mid-April and mid-May. 13.195 The requirement for further survey will depend on the quality of the ponds as breeding habitat and the number and distance of suitable breeding ponds from the Sub-area. It is likely that the great majority of suitable on-site habitat located around the Sub-area boundaries will be retained. However, surveys are still likely to be required to determine population size (if presence is confirmed), and the degree to which great crested newt are a constraint to any proposed development in terms of planning construction works and whether works will require a EPSM licence. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1157 Invertebrates 13.196 Sub-area 3 supports habitat types of high value to invertebrates i.e. unimproved and marshy grassland, ghyll and mixed woodland (with standing and fallen deadwood habitat), mature trees and edge/mosaic habitats. If these habitats are to be affected by development a terrestrial invertebrate survey is recommended. Survey effort should focus on woodland and grassland habitats and include a selection of survey methods to assess the range of invertebrate fauna likely to be present on-site. Lower plant survey 13.197 The northern part of the Sub-area includes ghyll woodland which is a Sussex BAP priority habitat and known to support important disjunct populations of ‘oceanic’ vascular plant and bryophyte species. Ghylls are very susceptible to changes in micro-climate, hydrogeology and physical disturbance. Potential impacts from development that may cause these changes are alterations to the local surface and ground water flow, removal of woodland cover in proximity to the ghyll and erosion and compaction from increased recreation. A survey of ghyll woodland within the Sub-area and 100m sections up and downslope of the Sub-area should be carried out. This is to determine the distribution and composition of the ghyll flora, the potential presence of uncommon, rare and protected pteridophtye (fern) and bryophytes (mosses and liverworts) species and to inform masterplanning for Sub-area 3/SDA 11. Outline mitigation relevant to Sub-area 3 Habitat retention and green infrastructure 13.198 Acid/marshy grassland and ghyll/PAW are the most ecologically important habitats present within the Sub-area and any development proposal should seek to retain and enhance these features. Lines of scattered trees and scrub extend out from mixed woodland in the north of the Sub-area, along both the eastern and western boundaries and, where possible, should also be retained and enhanced as part of any development proposal. 13.199 Where the loss of the woodland, scattered trees and scrub and/or grassland resources, described above, is unavoidable it will be necessary to carry out any required protected species surveys and mitigation prior to their removal and provide compensation for their loss. 13.200 All construction works taking place in the vicinity of adjacent woodland, retained scattered trees, scrub and grassland should conform to British Standard 5837:2005 Trees in Relation to Construction. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1158 13.201 The Sub-area includes part of Markly Wood PAW. Following Natural England’s Standing Advice on Ancient Woodland (2011a) a minimum buffer of at least 15m in width should be maintained between ancient woodland and any development boundary. Subject to the results of any further ecological surveys and liaison with relevant statutory bodies it may be necessary to increase the width of the buffer zone. 13.202 Drainage channels in close proximity to springs/flushes, feeding streams and/or ghylls should be managed to avoid changes to surface and ground water levels, any discharge of pollution or sediments and the diversion of water away from these habitats. All works near water courses and wetland features should adhere to best practice guidance to avoid adverse effects upon water quality, such as Pollution Prevention Guidance 5: Works and maintenance in or near water (Environment Agency, 2007). In addition, zones alongside ghyll woodland should remain undisturbed by creating buffer areas. Mitigation for protected species 13.203 Nesting birds: Woodland edge, scattered trees and dense scrub provide suitable nesting habitat for a variety of bird species. It is recommended that any vegetation clearance affecting nesting habitat should be undertaken outside of the bird nesting season which runs from March to August inclusive. 13.204 Bats and lighting: While different species of bat react differently to night time lighting, research has found that bats are sensitive to artificial lighting and that excessive lighting can delay bats from emerging, thus shortening the time available for foraging, as well as causing bats to move away from suitable foraging grounds or roost sites, to alternative dark areas (Jones, 2000). 13.205 Currently the whole Sub-area remains dark at night and to impacts on bats from lighting associated with any proposed development it will be necessary to limit light spillage and glare, particularly along woodland edge. This can be achieved by following accepted best practice (Institute of Ecology and Environmental Management 2006, Institute of Lighting Engineers 2007). Habitat compensation relevant to Sub-area 3 13.206 Any compensation planting should draw on best practice with regard to the use of native species of local provenance, avoidance of invasive species, and use of non-native species of known wildlife value provided in Chapter 19. Initial measures to be considered in development proposals for the Sub-area are as follows: Replacement planting to compensate for any loss of woodland, trees, scrub, hedgerows etc. should be provided as an integral part of any landscape The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1159 masterplanning for Sub-area 3/SDA 11. This should aim to retain the Sub-area’s value for any protected/UK BAP species confirmed present without recourse to offsite translocation. It should include only native species. If development involves the removal of semi-mature trees with potential to provide habitat for birds and bat in the future then there would be a particular value in using artificial bird and bat boxes to provide replacement nesting/roosting habitat. Habitat enhancement relevant to Sub-area 3 13.207 The following outline proposals for habitat enhancement should be considered as part of detailed proposals for development of Sub-area 3 to ensure that features of local ecological value contribute to the ecology of the District as a whole. Additional generic management recommendations for these features are provided in Chapter 19. Mixed Woodland 13.208 The regeneration of planted ancient woodland should be encouraged through the harvesting of on-site non-native trees and replanting with native broadleaved trees. Species planted should be typical of the local landscape (High Weald AONB). Some of the conifers are mature and the retention of scattered individual mature specimens can help to retain and potentially increase the biodiversity value of the Sub-area e.g. by providing standing deadwood habitat and bird nesting habitat. 13.209 Reinstatement of a coppicing system in neglected areas of mixed woodland is recommended to maintain habitat and structural diversity. Areas with evidence of historical coppicing (multi-stemmed trees with large stools) and with a rich ground flora, that is currently being shaded out, should be targeted for coppicing. Care should be exercised when coppicing areas bordering ghylls as trees/shrubs form an important part of this habitat, helping to maintain the particular micro-climate associated with this woodland type. Very old trees should not be coppiced as they may fail to regenerate successfully. Grassland 13.210 Where grassland to the north of the Sub-area is not grazed, it should be managed by at least one annual summer cut in July, with all arisings removed. In the absence of grazing this is an appropriate approach to ensure the ecological value of the grassland in the long-term. Where resources permit, it would be beneficial to carry out a second cut in late autumn (or later if ground conditions are suitable). This will remove any secondary/late season re-growth and reduce the build-up of thatch and nutrients which will reduce the botanical diversity of the grassland. Care should always be taken when cutting areas of marshy grassland to avoid compaction and/or erosion. Self-established saplings should be removed and the scrub edge (along the west boundary edge) cut back on a cyclical The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1160 basis. The spread of any bracken in this location should also be monitored as it may be necessary to manage dense stands by pulling/cutting/chemical treatment etc. Green infrastructure enhancements relevant to Sub-area 3 13.211 The Sub-area is within Heathfield Habitat Link BOA and any development proposals should consider the BOA targets which seeks to sympathetically manage the habitat mosaic present in the area and increasing the ‘permeability’ of the landscape for wildlife. 13.212 Many of the recommendations for habitat protection, creation and enhancement are likely to benefit both biodiversity and green infrastructure within the District. In order to ensure these issues are adequately addressed at the Sub-area level, specific recommendations referring to issues such as off-site habitat, hydrology, access and landscape are provided below: Mixed woodland and connected areas of trees/scrub should be largely retained to buffer the PAW and ghyll woodland and retain corridors of woodland along the northern edge of Heathfield. Any additional planting should be positioned so as to enhance green corridors on-site. Native tree and shrub species should be typical of the local landscape (High Weald AONB). From a green infrastructure perspective, the retention of marshy grassland will ensure that the natural drainage system for the Sub-area continues to function. Where marshy grassland is to be retained and incorporated within development proposals, it should form part of the wider SuDS for the Sub-area/SDA. Detailed hydrological studies should be carried out to ensure that development does not adversely affect water supply or water quality within the adjacent ghyll stream. SuDS and other pollution control measures may be required to ensure that adverse effects do not occur. Subject to findings of botanical and invertebrate surveys and hydrological investigations the creation of a pond within the area of marshy grassland or adjoining scrub could improve conditions for amphibians potentially breeding in the locality and strengthen links between any breeding populations associated with nearby ponds e.g. in Sub-area 2. If any proposed development comprises large areas of buildings and hardstanding the use of SuDs schemes, green roofs and walls should be considered to enhance the biodiversity value of the Sub-area, protect water quality and reduce the rate of runoff. The use of native tree and shrub planting and species of known wildlife value in landscape schemes should be considered in detailed landscape proposals as this The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1161 will provide opportunities for wildlife at the smallest scale of development, ensuring that opportunities for common species are not diminished. 13.213 Further detail on measures to enhance biodiversity and green infrastructure are provided in Chapter 19. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1162 HABITAT SURVEY: SUB-AREA 4 - LAND ADJACENT TO THE POLICE STATION INCLUDING REYNARDS AND WOODHATCH Overview 13.214 All parts of Sub-area 4 were surveyed on the 24th May 2011. Sub-area 4 is the largest Sub-area within SDA 11 (4.5ha) occupying 48% of the total area. It includes two properties (Reynards and Woodhatch) and their associated gardens and the larger fields behind these. Habitats present within the Sub-area included: improved grassland, scattered trees, scattered scrub hedgerow and dry ditches. The site slopes south to north towards the adjacent Markly Wood PAW. Improved grassland 13.215 The grassland in this Sub-area is of much poorer quality than elsewhere within the overall SDA, being improved and dominated by the rhizomatous form of smooth meadow-grass over large areas. However, sweet vernal-grass is frequent on the steeper slopes to the north. Yorkshire fog, common bird’s-foot-trefoil and lesser stitchwort are very occasional in the sward. A localised wet area supported creeping Jenny and thyme-leaved speedwell (T12). Very narrow marginal habitats along old ditch banks, lines of trees and the woodland edge provide the greatest interest with relict acid grassland/woodland edge species including slender St. John’s-wort, heath bedstraw, foxglove, oval sedge, bugle, bluebell, wood sorrel and wood sage (T13). Disturbed areas of sward around the remains of a large bonfire were found to support a few casual species including field mouse-ear, lesser trefoil, thyme-leaved speedwell and procumbent pearlwort. Scattered trees and scrub 13.216 Scattered trees and scrub are mainly represented by lines of mature pedunculate oak along old field boundaries, with a few silver birch trees and a multi-stemmed tree of hybrid birch at the northern end of the Sub-area, the latter having bluebells and wood anemone at its base. It is understood that some of the Sub-area’s mature oaks were recently felled and burned. A single wild cherry tree was also present on the eastern boundary of the Sub-area. Invasive plant species 13.217 A stand of Japanese knotweed with approximately 100 stems was present in the northernmost point of the Sub-area, adjacent to Markly Wood (T11). Hedgerow 13.218 A short section of old, layed hedge was present along the east side of the entrance track into Sub-area 4 (from the A265). Native species included hornbeam, holly, sweet chestnut and hazel. Wilson’s honeysuckle had been planted and was locally frequent. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1163 13.219 A mixed species hedgerow was present along the southern boundary of Woodhatch and comprised locally dominant hawthorn and locally frequent holly and Wilson’s honeysuckle. Dry Ditches 13.220 Dry ditches that occasionally may flood were present along the lines of scattered trees running north to south across the centre of the site. These mark old field boundaries and supported a remnant flora (mainly in the north) including soft rush, bugle, yellow pimpernel, marsh bedstraw, marsh thistle, and wood sage on the upper slopes. Residential gardens of Reynards and Woodhatch 13.221 The grounds of Reynards (Building 1) and Woodhatch (Building 2) were dominated by improved grassland (see description above). Scattered trees comprised mostly of pedunculate oak, with occasional Scot’s pine and other conifer species , adjacent to the southern boundary of Reynards and along the open boundary separating the two properties. A mixed species hedgerow had been planted along the southern boundary of Woodhatch (see description above). Buildings Building 1 13.222 The main building within the grounds of Reynards. A two storey, brick-built building of modern design with tiled and pitched cross-gabled roofs. Hanging tiles were present on all façades of the upper floor. Building 2 13.223 The main building within the grounds of Woodhatch. A two storey, brick-built building of modern design with tiled and pitched roofs with a complex design. Two large chimney stacks were also present. A small brick-built garage with tiled, pitched roof was present to the south of the main building. Fauna 13.224 The following bird species were recorded during the survey; great tit, chiffchaff, blue-tit, wood pigeon and green woodpecker. Target Notes relevant to Sub area 4 13.225 Target Notes (T) are features within the Sub-area assessed as being of ecological interest and are marked on the Habitat Map in Appendix. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1164 Target Note 11 13.226 Japanese knotweed along the northern boundary with Markly Wood – invasive plant species. Target Note 12 13.227 Relict semi-improved wildflower species indicative of wet/heavier soils – creeping Jenny, lesser stitchwort, thyme-leaved speedwell etc. Target Note 13 13.228 Very narrow marginal habitats along old ditch banks, lines of trees and the woodland edge provide the greatest interest with relict acid grassland/woodland edge species including slender St. John’s-wort, heath bedstraw, foxglove, oval sedge, bugle, bluebell, wood sorrel and wood sage. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1165 PROTECTED SPECIES RISK ASSESSMENT: SUB-AREA 4 - LAND ADJACENT TO THE POLICE STATION INCLUDING REYNARDS AND WOODHATCH 13.229 The habitats at Sub-area 4 were evaluated as to their likelihood to provide sheltering, roosting, nesting and foraging habitat for the following species/species groups: Breeding birds Bats Badgers Reptiles Great crested newt Dormice Invasive plant species 13.230 These species were selected for further consideration because the results of the desk study revealed that they occur in the vicinity of the SDA and potentially suitable habitat is present within Sub-area 4. The results of the field survey, combined with information from the desk study, are presented in Table 9 below. The relevant legislation and policies relating to protected species is presented within Chapter 19. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1166 Table 9: Assessment of potential presence of invasive and protected species within Sub-area 4 of SDA 11. Species Main legislation (see Chapter 16) Breeding birds Wildlife and Countryside Act 1981 (as amended) selected species Schedules 1 and 8. Bats Wildlife and Countryside Act 1981 (as amended) Schedule 5. The Conservation of Habitats and Species Regulations 2010 Schedule 2. Badger Protection of Badgers Act 1992. Widespread reptiles Wildlife and Countryside Act, 1981 (as amended) Schedule 5 (partial protection) Reason for consideration Likelihood of occurrence Scattered trees, scrub, introduced shrubs and buildings provide suitable breeding habitat for common garden and potentially some woodland species. Open countryside to the east, north and west and gardens to the south provide a wider foraging network. Adjacent woodland complex provides extensive off-site foraging, commuting and roosting habitat. On-site grassland provides foraging habitat. The Sub-area is located on the north-western edge of Heathfield with excellent connectivity with open countryside to the west, north and east. Widespread and wide-ranging species, especially in the south and west of the UK. Scattered tree and scrub habitat is suitable for settbuilding. On-site grassland provides foraging habitat. HIGH. Areas of suitable breeding habitat included the boundary with Sub-area 3, the line of scattered trees extending south form Markly Wood and the gardens and properties of Reynards and Woodhatch. These provided suitable nest sites for a variety of bird species. The periphery of the Sub-area is well connected to off-site foraging resources in the wider countryside, particularly Markly Wood to the north. 65 species recorded within a 2km radius of the SDA. MEDIUM (roosting) MEDIUM (foraging). Extensive areas of connected woodland stretch to the west and north providing both suitable roosting, and foraging opportunities. Extensive areas of improved grassland are of low value as foraging habitat. Two main buildings (and one garage) were present on-site and provide some features of value to roosting bats such as complex roof structures with voids and raised tiles etc. Seven bat species are recorded within a 2km radius of SDA 11 including a Natterer’s hibernation roost 40m east of Sub-area 4. MEDIUM. The periphery of the Sub-area and adjacent wooded habitat included good cover and connectivity for badger to move across the wider landscape. Areas most suitable for sett construction were limited to the northern and eastern boundary. Pasture fields dominated the Sub-area and provided extensive foraging habitat. A preliminary search of the Sub-area did not find any signs of badger, but this does not guarantee their absence as they are a mobile species. Badger records are not provided as part of the SxBRC data search. MEDIUM. The scrub/grassland edge provides habitat for widespread reptile species, but this is generally restricted to the north-west, north and east boundaries and the line of trees extending south from Markly Wood. The Sub-area is located in a rural area and connected to suitable off-site habitat to the west (Sub-area 3), south (private gardens) and east (Markly Wood). The Gardens of Reynards and Woodhatch are of very limited value to reptiles as they are dominated by regularly mown improved Boundary vegetation including scattered trees, scrub, banks and ditches provides potential hibernating habitat. Interface between grassland and woodland edge provides basking and foraging opportunities for widespread species of reptile. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1167 Table 9: Assessment of potential presence of invasive and protected species within Sub-area 4 of SDA 11. Species Main legislation (see Chapter 16) Great crested newt Wildlife and Countryside Act 1981 (as amended) Schedule 5. The Conservation of Habitats and Species Regulations 2010 Schedule 2. Dormouse Wildlife and Countryside Act 1981 (as amended) Schedule 5. The Conservation of Habitats and Species Regulations 2010 Schedule 2. Invasive plants species Section 14 and Part II of Schedule 9 of the Wildlife and Countryside Act 1981 (as amended) Reason for consideration Suitable terrestrial habitat is present around the Sub-area boundary. Two ponds are identified within a 500m radius, which is the guideline distance (English Nature, 2001) which great crested newt may commute between breeding ponds and terrestrial sites. The Sub-area is located in a rural setting on the north-western edge of Heathfield. The Sussex countryside has an abundance of shallow ponds suitable as breeding sites. Scattered trees and scrub provide suitable nesting habitat. There is a wide range of invasive plant species of which a number of widespread species occur in woodlands, aquatic and wetland habitats, and disturbed sites or close to settlements. As such there is potential for invasive plants to be present in the Sub-area. Likelihood of occurrence grassland. There are off-site records for all four species of widespread reptile from the data search, the closest being a 1997 grass snake record 428m to the south of Sub-area 4. MEDIUM. There is no suitable breeding habitat present on-site. The nearest pond is 75m to the west in Sub-area 2, although this is currently considered sub-optimal as it is newly created. There are no records within 500m of the Sub-area, the closest being a 2006 record at Waldron Ghyll, 1.2km south of Sub-area 4. Three additional ponds within 500m are visible on OS mapping, all are in Markly Wood to the north, the closest of which is 350m northeast of Sub-area 4. There are no barriers to dispersal, but the presence of abundant habitat around these ponds may limit the need for animals to disperse to the Sub-area. Suitable terrestrial habitat is restricted to scattered trees and scrub around the western and north-western boundary. Reynards and Woodhatch have low potential to support terrestrial great crested newt. LOW. Potentially suitable on-site habitat is limited to the narrow band of scattered trees and scrub bordering Sub-area 3 and the line of scattered trees extending south form Markly Wood. Whilst these areas are connected to extensive areas of off-site woodland, suitable food and nest building plants such as hazel, bramble and honeysuckle were absent/very limited and the habitat structure sub-optimal. A 1998 data record was returned from Cross in Hand (Sellyns Farm) 1.65km west of Sub-area 4. PRESENT. A stand of Japanese knotweed with approximately 100 stems is present on the northernmost point of the Sub-area, adjacent to Markly Wood. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1168 NATURE CONSERVATION EVALUATION: SUB-AREA 4 - LAND ADJACENT TO THE POLICE STATION INCLUDING REYNARDS AND WOODHATCH 13.231 On the basis of the information available from the Phase 1 habitat survey, data search and review of BAPs, Sub-area 4 has been evaluated in terms of its potential for biodiversity, support of protected species and habitats, and the contribution the area makes as part of the wider landscape. A combined evaluation of the nature conservation value of the Sub-area using standard criteria developed by IEEM (2006) and selected criteria from Defra's (2006) 'Local Sites' evaluation guidance is provided in Table 10 below. 13.232 The biodiversity value of protected and BAP species within the Sub-area is a preliminary evaluation based upon the desk study records, habitat suitability and the conservation status of the species in question. It should be noted that where European Protected Species or BAP species are present on-site they may be valued at a lower level/scale where it is considered likely that populations would not be of sufficient importance to justify designation at a higher level. However, regardless of their biodiversity value, such species are still subject to national and/or European legislation. 13.233 Key aspects of relevant planning policy and legislation regarding conservation, including an explanation of species referred to as being of 'Principal Importance for the Conservation of Biodiversity', European Protected Species and BAP species and habitats, are provided in Chapters 16-18. Table 10: Combined Evaluation of the Nature Conservation Value of Sub-area 4 of SDA 11. Criteria Features of International Importance Features of National Importance 9 Remarks Sub-area 4 is not subject to any international statutory nature conservation designations. The closest site of International Importance is Ashdown Forest designated as both a SAC and SPA, located approximately 11.5km to the north-west. Ashdown Forest is important for its lowland wet and dry heath habitats and associated bird assemblage. No heathland habitat or any supporting habitats that maintain the integrity of this designated area are present. Sub-area 4 is not subject to any national nature conservation designations. It is not considered that any habitats or populations or assemblages of species within the Sub-area would meet the criteria for the designation of 9 SSSIs at an appropriate geographic level . JNCC Guidelines for selection of biological SSSIs (see http://jncc.defra.gov.uk/page-2303#download). The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1169 Table 10: Combined Evaluation of the Nature Conservation Value of Sub-area 4 of SDA 11. Criteria Remarks Features of Regional (Sussex) Value Sub-area 4 is not subject to any non-statutory nature conservation designations. The north-west, north and eastern boundaries are adjacent to Markly Wood PAW. The Weald area of south-east England contains a concentration of ghyll woodland which is included under the county’s Woodland BAP and significant at this level. Features of District (Wealden) Importance There are no ecological features present on-site of value at the district level. Features of Local (Heathfield) Importance A number of protected and UK BAP species may occur at the Sub-area, as follows: - Reptiles, including slow-worm, common lizard and grass snake; - Birds such as house sparrow, starling, dunnock and song thrush; - Amphibians such as great crested newt and common toad; - Invertebrates such as stag beetle; - Small mammals such as hedgehog and dormice; and - Bats, such as soprano, noctule bat and brown long eared. Based on the quality and extent of habitat present, it is considered that populations of these species would be significant at the local level. There is a single UK BAP priority habitat present on-site: hedgerows (see Habitat Map) although this habitat is limited in extent and not considered to be an outstanding example of its type and is therefore of no more than local importance. The Sub-area is not managed or publically accessible and therefore woodland, scattered trees and scrub are relatively undisturbed and provide cover and foraging opportunities for a breeding bird assemblage of value in a local context. Features of Value within the immediate vicinity of the Sub-area The remaining habitats at the Sub-area are dominated by improved grassland which is likely to be of some value as foraging, cover and breeding sites for a range of generalist species and therefore of value in maintaining the ecology of the area. However, this is a common and widespread habitat that does not generally support rare species or diverse assemblages of species and is therefore of value in the immediate vicinity of the Sub-area. Features of Secondary and Supporting Value / Connectivity within the landscape Woodland, linear belts of scattered trees/scrub and hedgerows may provide connectivity between off-site ecological receptors such as small fields, woodland copses, hedgerows and tree lines. On-site habitats may extend the foraging and breeding range for off-site species using the adjacent woodland complex. The Sub-area may also function as a buffer to Markly Wood PAW and the urban edge of Heathfield and provide a wildlife corridor and/or stepping stones for mobile species moving across the Heathfield urban-rural fringe. Social Value / Recorded History and Cultural Associations The Sub-area is privately owned. It is accessed via a track alongside the Police Station on the A265. The primary value of Sub-area 4 is in its aesthetic value to those residents whose houses back onto the Sub-area, affording them views over the countryside. No recorded ancient trees were present on-site however several mature The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1170 Table 10: Combined Evaluation of the Nature Conservation Value of Sub-area 4 of SDA 11. Criteria Remarks pedunculate oak and birch trees were present. Trees receiving TPOs are present in the grounds of Reynards and Woodhatch and provide visual amenity value (please see Habitat Map for location). Off-site trees along the eastern boundary of the Sub-area are also subject to a group TPO (as part of Markly Wood). Economic value The fields are likely to have been historically grazed, but are now mechanically cut. Whilst it is recommended that mature oaks be retained, they could potentially be harvested for timber. All remaining habitats and species do not currently provide a resource that could be exploited for their economic value. Size and extent The Sub-area measures 4.5ha (total SDA area 9.33ha) with improved grassland occupying approximately 95% of the total area. Scattered trees, scrub and tall-ruderal occupy the remaining area. The Sub-area therefore comprises a small number of habitat types, with potential to support a low to moderate range of common and protected species. Fragility The woodland and mature trees/scrub and native hedgerows are susceptible to ground disturbance. Remaining habitats i.e. non-native hedgerows, improved grassland, young planted and self-established trees, scrub, tall-ruderal are relatively recently established, species poor, would rapidly recover from impacts and can be restored/resown. Typicalness All on-site habitats are typical of a lowland agricultural landscape and are not outstanding examples of their types. Summary of Nature Conservation Evaluation 13.234 On the basis of the above criteria, Sub-area 4 is considered to be of ecological value within the local context. It is dominated by fields of improved grassland which are typically a habitat of low ecological value. It has potential to support a range of declining and BAP species, including those protected at a National and European level i.e. badger, reptiles, great crested newts and bats, although this is strongly associated with boundary habitats and linear features, and additionally, in the case of roosting bats, the properties of Reynards and Woodhatch. The legal and policy implications associated with these species are detailed in Chapter 16 and 17. 13.235 The Sub area also appears to form part of the catchment of a ghyll stream flowing into Markly Wood and provides buffering and supporting habitat to Markly Wood PAW along its eastern boundary. Due to the restricted distribution of ghyll features in South-East England, in this respect the Sub-area is considered to be of regional importance in terms of maintaining the hydrology of the stream, and boundary habitat would be important in buffering it from the effects of any future development. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1171 GREEN INFRASTRUCTURE APPRAISAL: SUB-AREA 4 - LAND ADJACENT TO THE POLICE STATION INCLUDING REYNARDS AND WOODHATCH Water bodies and local catchment area 13.236 No standing water was present within Sub-area 4. Ghyll woodland (part of Markly Wood PAW) is adjacent to the northern half of the eastern boundary. Two ditches, orientated south to north, dissect the Sub-area and feed into adjacent areas of Markly Wood at the Sub-area’s northern boundary. The most easterly ditch is likely to feed into the adjacent ghyll. Habitat connectivity 13.237 Markly Wood encapsulates the north-west, north and eastern boundaries of Sub-area 4. Consequently, the Sub-area is reasonably well connected to the larger woodland complex located to the north and west of Heathfield, via on-site woodland edge, scattered trees and scrub and two lines of mature trees (likely to be former hedgerows). These habitats provide a potential wildlife corridor for a range of mobile species such as bats, birds, invertebrates, badgers and small mammals. These species are potentially commuting along the woodland edge, within the Sub-area and moving across the Heathfield urban-rural fringe into the wider Wealden countryside and Heathfield Habitat Link BOA. Sustainable transport routes/PROW 13.238 Sub-area 4 is privately owned and no Public Right Of Way (PROW) is present. There is currently no network of cycle routes serving the Sub-area. There may also be an opportunity to increase the connectivity of any potential development with the Ancient Woodland located on the eastern boundary (The Heathfield Millennium Green) through the provision of pathways and cycle ways. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1172 CONCLUSIONS AND RECOMMENDATIONS: SUB-AREA 4 - LAND ADJACENT TO THE POLICE STATION INCLUDING REYNARDS AND WOODHATCH 13.239 All parts of the Sub-area (with exception to the entrance track and the northern half of residential curtilages) fall within the boundaries of the statutory designated High Weald AONB. 13.240 The Sub-area is not subject to any statutory or non-statutory nature conservation designations. The nearest statutory designated site for nature conservation is Heathfield Park SSSI located 1.6km to the east of Sub-area 4. The nearest non-statutory designated nature conservation site is Oaken & Furlong Woods SNCI located 1.75km to the northeast of Sub-area 4. On the basis of information available at the time of report production, it is considered unlikely that the Sub-area performs an important supporting role for these sites based upon the habitats present, the features for which the sites are designated and the degree of connectivity between them. 13.241 Overall, Sub-area 4 is considered to be of ecological value within a local context. Approximately 95% of the Sub-area comprised of improved grassland which is typically a habitat of low ecological value. However, the Sub-area does have potential to support a range of common, protected and BAP species. This interest is strongly associated with boundary habitats and linear features and additionally, in the case of roosting bats, the properties of Reynards and Woodhatch. 13.242 The Sub-area also provides a secondary and supporting role to the network of ecological receptors surrounding it, primarily by: Buffering Markly Wood PAW which is present along its eastern boundary. Providing wildlife corridors for species moving between the urban areas of Heathfield and the wider Wealden countryside. 13.243 The following UK BAP habitats/species are or have potential to be present within the Sub-area: Reptiles, including slow-worm, common lizard, grass snake and adder; Birds such as house sparrow, starling, dunnock and song thrush; Amphibians such as great crested newt and common toad; Invertebrates such as stag beetle; Small mammals such as hedgehog and dormice; Bats, such as soprano pipistrelle, noctule bat and brown long eared; and The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1173 Hedgerows. 13.244 BAP habitats/species are not necessarily rare but under PPS9 and the NERC Act 2006 are all of principal importance for biodiversity (ODPM, 2005) and are of material consideration in the planning process. None of the BAP habitats or populations of BAP species currently known to be present at the Sub-area are considered as notable or exceptional examples of their type. Recommended further surveys relevant to Sub-area 4 Overview 13.245 The surveys recommended below assume the loss of or damage to suitable habitat should the Sub-area be proposed for development. There is potential to avoid and/or limit impacts through habitat retention and protection (see below). The final approach to surveys will have to be based on consideration of detailed proposals for Sub-area/SDA, though in all cases published best practice should be followed with regard to survey methodology etc. 13.246 To provide a sufficient baseline of data and mitigate against any potential impact on declining, BAP and protected species/habitats at Sub-area 4, further surveys for reptiles, bats, badger, great crested newts and invasive plants are recommended. Reptiles 13.247 The open grassland areas within Sub-area 4 appeared to be regularly managed with a low sward height for much of the year. This management would in all likelihood restrict any resident reptiles to edge habitats along the eastern, northern and western boundaries. The domestic back gardens in this area were also clearly regularly maintained with a short sward of improved grassland. However, given the relative size of Sub-area 4 it is possible that reptiles of more than one species could exploit edge habitat particularly in the north-western corner. 13.248 A minimum of a seven survey visits, following current guidelines (Froglife, 1999, English Nature 2004; Natural England 2011b), should be carried out to establish the presence/absence and distribution of reptiles. Artificial refugia made from roofing felt and from corrugated steel sheet should be employed and used to survey the grassland in the north-west and sample other habitats throughout the area. The optimum time is generally late spring, from April through to June and in the early autumn in September. Where possible, survey effort should be spread across the recording season i.e. March-October. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1174 Bats 13.249 Both of the domestic premises present on-site were detached and substantial in size. The age and design of both buildings was such as to have an increased likelihood of bats being present if judged against current guidelines (BCT, 2007). The potential for a roost is increased due to the proximity of high value foraging habitats and other buildings suitable for roosting. The trees throughout Sub-area 4 were not of a particularly high value for roosting but this should be more fully determined through a tree assessment. 13.250 Following current guidelines (BCT, 2007) further bat surveys are recommended to assess the presence or potential presence of any bat roosts, as well as the function the Sub-area might provide for foraging and commuting. This should include a detailed building inspection of both domestic premises, tree inspections of all semi-mature/mature trees within the boundary including within the gardens of the two houses and activity and emergence surveys. Emergence and activity surveys must be carried out between May and September. Badger 13.251 The open areas of grassland that dominate this Sub-area provide a good foraging resource for badgers, although there is not likely to be a variety of foraging opportunities throughout the year. The potential for sett building is primarily limited to the woodland edge habitats and the remnant ditch and bank with tree cover running through the centre of the area. 13.252 In order to assess the use of the Sub-area by badger a survey should be carried out in all areas of suitable on-site sett-building and foraging habitat to look for evidence of this species. Survey effort should also include suitable off-site areas within a minimum 30m distance of the Sub-area boundary. This is in line with current Natural England recommendations and the possibility of sett disturbance caused by construction activities (Highways Agency, 2001; Natural England, 2007). 13.253 Holes attributed to badger should be classified as well used, partially used or disused in line with the methodology given in the National Badger Survey (Cresswell et al. 1990; Wilson et al. 1997). Setts should be classified as main, annexe, subsidiary and outlier (Wilson, Harris & McLaren, 1997). Surveys to identify setts should be carried out in the winter while surveys to establish the level of foraging and the likely impact of loss of foraging habitat and mitigation required should be conducted in the summer. Great crested newt 13.254 There was no potential breeding habitat within this Sub-area and the suitable terrestrial habitat appeared to be relatively limited. As with reptiles, the areas of suitable cover and The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1175 foraging are restricted primarily to the edge habitats particularly in the north-western section. The central tree line could also provide a supporting function for foraging and for hibernation. It is therefore recommended that a Habitat Suitability Index (HSI) survey, following Oldham et al (2000), is carried out on all ponds within a 500m radius of the Subarea’s boundaries that do not have significant barriers to dispersal. 13.255 Using the results from the HSI, presence/absence surveys of ponds within 500m of the Sub-area that do not have any significant barriers to dispersal between them and the Sub-area may need to be carried out. Four presence/absence surveys should be carried out following best practice guidelines (English Nature, 2001) between mid-March and mid-June with at least two of these surveys between mid-April and mid-May. 13.256 The requirement for further survey will depend on the quality of the ponds as breeding habitat and the number and distance of suitable breeding ponds from the Sub-area. It is likely that the great majority of suitable on-site habitat around boundaries will be retained. However, surveys are still likely to be required to determine population size (if presence is confirmed), and the degree to which great crested newt are a constraint to any proposed development in terms of planning construction works and whether works will require a EPSM licence. Invasive plant species 13.257 Japanese knotweed is present along the northern boundary and is an invasive plant species included on Schedule 9 of the Wildlife and Countryside Act 1981 (as amended) under which it is an offence to plant or otherwise cause these species to grow in the wild. It is possible that it could be spread during construction works and therefore a survey is recommended to accurately determine its extent, and to inform a method statement for works which should follow current guidelines (Environment Agency, 2006; Netregs, 2011). Outline mitigation relevant to Sub-area 4 Habitat retention and protection 13.258 Sub-area 4 is the largest Sub-area within SDA 11 and essentially comprises one large field of improved grassland, which is typically a habitat of low ecological value together with two residential properties. Three lines of scattered trees, scrub and ditches extend south from the northern boundary with Markly Wood. These therefore function as important corridors for wildlife moving both on-site and across the wider landscape. Development proposals should seek to retain and enhance these features. 13.259 Where the loss of the scattered trees, scrub and ditches, described above, is unavoidable it will be necessary to carry out any required protected species surveys and mitigation prior to their removal and provide compensation for their loss. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1176 13.260 All construction works taking place in the vicinity of adjacent woodland, retained scattered trees, scrub and ditches should conform to British Standard 5837:2005 Trees in Relation to Construction. 13.261 Markly Wood PAW is adjacent to the eastern boundary of the Sub-area. Following Natural England’s Standing Advice on Ancient Woodland (2011a) a minimum buffer of at least 15m in width should be maintained between ancient woodland and any development boundary. Subject to the results of any further ecological surveys and liaison with relevant statutory bodies it may be necessary to increase the width of the buffer zone. Consideration should also be given to maintaining a similar buffer along the northern boundary, which is adjacent to undesignated areas of Markly Wood. 13.262 Drainage channels in close proximity to springs/flushes, feeding streams and/or ghylls should be managed to avoid changes to surface and ground water levels, any discharge of pollution or sediments and the diversion of water away from these habitats. All works near water courses and wetland features should adhere to best practice guidance to avoid adverse effects upon water quality, such as Pollution Prevention Guidance 5: Works and maintenance in or near water (Environment Agency, 2007). In addition, zones alongside ghyll woodland should remain undisturbed by creating buffer areas. Mitigation for protected species 13.263 Nesting birds: Woodland edge, scattered trees and dense scrub provide suitable nesting habitat for a variety of bird species. It is recommended that any vegetation clearance affecting nesting habitat should be undertaken outside of the bird nesting season which runs from March to August inclusive. 13.264 Bats and lighting: While different species of bat react differently to night time lighting, research has found that bats are sensitive to artificial lighting and that excessive lighting can delay bats from emerging, thus shortening the time available for foraging, as well as causing bats to move away from suitable foraging grounds or roost sites, to alternative dark areas (Jones, 2000). 13.265 Currently parts of the Sub-area remain relatively dark at night and to minimise impacts on bats from lighting associated with any proposed development it will be necessary to limit light spillage and glare. This can be achieved by following accepted best practice (Institute of Ecology and Environmental Management 2006, Institute of Lighting Engineers 2007). The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1177 Habitat compensation relevant to Sub-area 4 13.266 Any compensation planting should draw on best practice with regard to the use of native species of local provenance, avoidance of invasive species, and use of non-native species of known wildlife value provided in Chapter 19. Initial measures to be considered in development proposals for the Sub-area are as follows: Replacement planting to compensate for any loss of woodland, trees, scrub, hedgerows etc. should be provided as an integral part of any landscape masterplanning for Sub-area 4/SDA 11. This should aim to retain the site’s value for any protected/UK BAP species confirmed present without recourse to off-site translocation. It should include only native species. If development involves the removal of semi-mature trees with potential to provide habitat for birds and bat in the future then there would be a particular value in using artificial bird and bat boxes to provide replacement nesting/roosting habitat. Habitat enhancement relevant to Sub-area 4 13.267 The following outline proposals for habitat enhancement should be considered as part of detailed proposals for development of Sub-area 4 to ensure that features of local ecological value contribute to the ecology of the District as a whole. Additional generic management recommendations for these features are provided in Chapter 19. Scattered trees/scrub and ditches 13.268 Trees and scrub species had recently been removed from the line of trees and scrub extending out from Markly Wood into the centre of the Sub-area. This feature included a ditch and bank system, remnant woodland and wetland plant species and is highly likely to represent an old field boundary/hedgerow. Consideration should be given to replanting this (and similar) linear on-site feature to form a continuous hedgerow with standard trees and to re-profile/re-instate the ditch and bank system. This should ideally link the southern boundary of the Sub-area (and Sub-area 5 and 6) with the northern boundary, providing a valuable wildlife corridor and landscape feature within the overall SDA. Green infrastructure enhancements relevant to Sub-area 4 13.269 The Sub-area is partly within Heathfield Habitat Link BOA and any development proposals should consider the BOA targets which seek to sympathetically manage the habitat mosaic present in the Area and increase the ‘permeability’ of the landscape for wildlife. 13.270 Many of the recommendations for habitat protection, creation and enhancement are likely to benefit both biodiversity and green infrastructure within the District. In order to ensure these issues are adequately addressed at the Sub-area level, specific recommendations The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1178 referring to issues such as off-site habitat, hydrology, access and landscape are provided below: Lines of scattered trees and scrub along dry ditches and the north-western boundary should be largely retained to buffer adjacent areas of Markly Wood which includes both ghyll woodland and PAW. At a landscape scale this will assist help to retain corridors of woodland along the northern edge of Heathfield. Any additional planting should be positioned so as to enhance green corridors on-site. Native tree and shrub species should be typical of the local landscape (High Weald AONB). From a green infrastructure perspective, the retention (and enhancement) of ditches will ensure that the natural drainage system for the Sub-area continues to function. Where ditches are to be retained and incorporated within development proposals, they should form part of the wider SuDS for the Sub-area/SDA. Detailed hydrological studies should be carried out to ensure that development does not adversely affect water supply or water quality within the adjacent ghyll stream. SuDS and other pollution control measures may be required to ensure that adverse effects do not occur. Subject to hydrological investigations the creation of ponds and/or the re-profiling of ditches to create areas of standing water could improve conditions for amphibians potentially breeding in the locality and strengthen links between any breeding populations associated with nearby ponds. If any proposed development comprises large areas of buildings and hardstanding the use of SuDs schemes, green roofs and walls should be considered to enhance the biodiversity value of the Sub-area, protect water quality and reduce the rate of runoff. The use of native tree and shrub planting and species of known wildlife value in landscape schemes should be considered in detailed landscape proposals as this will provide opportunities for wildlife at the smallest scale of development, ensuring that opportunities for common species are not diminished. 13.271 Further detail on measures to enhance biodiversity and green infrastructure are provided in Chapter 19. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1179 HABITAT SURVEY: SUB-AREA 5 - HOLMHURST, HIGH STREET Overview 13.272 Sub-area 5 was surveyed on the 24th May 2011. Sub-area 5 occupies 0.17ha and comprises the property, and associated buildings and garden, of Holmhurst. As such, it contains the most modified habitats within the SDA. Habitats present within the Sub-area included; buildings, hardstanding, improved grassland, scattered trees, introduced shrubs and hedgerows. Sub-area 5 is located between Sub-area 4 and Sub-area 6 and is accessed from Heathfield High Street (A265). Hedgerows 13.273 A species poor native beech hedge was present along the western boundary with Reynards (Sub-area 4). A mixed hedgerow was present along the southern boundary and comprised Wilson’s honeysuckle, garden privet and hawthorn. Improved grassland 13.274 A small area of lawn was present at the front of the house and comprised abundant perennial rye-grass and white clover with frequent common bent, daisy and selfheal. Violet was locally frequent. Scattered trees and introduced shrubs 13.275 Planted trees and shrubs included a moderate range of standard horticultural stock tolerant of acid substrates, including Scot’s pine, rhododendron, cherry, bamboo, cypress, mop-head hydrangea etc. A vegetable growing area was present in the rear garden along with mature apples trees. Buildings and hardstanding 13.276 The main house of Holmhurst (Building 3) was a large brick, two storey building with wooden soffits and tiled, pitched roof. It was, generally, in a good state of repair although gaps between the soffits and building façade were present and some tiles were missing/raised. Fauna 13.277 No fauna was observed during the Phase 1 survey. Target notes relevant to sub-area 5 13.278 No features were present that required target notes. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1180 PROTECTED SPECIES RISK ASSESSMENT: SUB-AREA 5 - HOLMHURST, HIGH STREET 13.279 The habitats at Sub-area 5 were evaluated as to their likelihood to provide sheltering, roosting, nesting and foraging habitat for the following species/species groups: Breeding birds Bats Badgers Reptiles Great crested newt Invasive plant species 13.280 These species were selected for further consideration because the results of the desk study revealed that they occur in the vicinity of the SDA and potentially suitable habitat is present within Sub-area 5. The results of the field survey, combined with information from the desk study, are presented in Table 11 below. The relevant legislation and policies relating to protected species is presented within Chapter 16 and 17. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1181 Table 11: Assessment of potential presence of invasive and protected species within Sub-area 5 of SDA 11 Species Main legislation (see Chapter 16) Breeding birds Wildlife and Countryside Act 1981 (as amended) selected species Schedules 1 and 8. Bats Wildlife and Countryside Act 1981 (as amended) Schedule 5. The Conservation of Habitats and Species Regulations 2010 Schedule 2. Badger Protection of Badgers Act 1992.

The Conservation of Habitats and Species Regulations 2010 Schedule 2. Reason for consideration Likelihood of occurrence Scattered trees, scrub, introduced shrubs and hedgerows provide suitable breeding habitat. Surrounding rural landscape to the north may also provide an important foraging resource. Mature/semi-mature scattered trees provide suitable roosting habitat. Boundary features of hedges and tree lines provide suitable foraging and commuting habitat. Any building, but particularly those of early or pre twentieth century construction can provide suitable roosting areas for both void and crevice dwelling species. Widespread and wide-ranging species, especially in the Sussex and the south-east of the UK. Badgers are known to regularly exploit domestic gardens on the urban fringe. Domestic gardens can contain suitable habitat features such as compost piles and fire wood stacks that can be exploited by reptile species. Slow worms are often associated with domestic gardens. Hedgerows and gardens can provide suitable cover and foraging opportunities for this species. Two ponds are identified within a 500m radius, which is the guideline distance (English Nature, 2001) which great crested newt may commute between HIGH. Scattered trees, dense shrubs and hedgerows are likely to provide a foraging and nesting resource for common species of bird, although the extent of suitable habitat was limited. Parts of the house, such as wooden soffits, may also provide suitable habitat for urban species such as house sparrow. 65 species recorded within a 2km radius of the SDA. HIGH (roosting) MEDIUM (foraging). Despite the relatively small and discrete size of this Sub-area, the residential building has some potential for a roost as it provides features such as complex roof structures with voids and missing/raised tiles. Back gardens are often used by bats for foraging due to the higher diversity/density of flying invertebrates that may utilise well planted (diverse) ornamental schemes (as present on-site). Seven bat species are recorded within a 2km radius of SDA 11 including a Natterer’s hibernation roost 120m east of Sub-area 5. NEGLIGIBLE. Although domestic gardens are regularly used by badgers no signs of use were observed during the survey and there was limited cover that could have obscured a sett. Badger records are not provided as part of the SxBRC data search. LOW. The garden located in Sub-area 5 is managed and the lawn regularly mown. Opportunities for species such as slow worms were limited to less intensively managed edge habitats. There are off-site records for all four species of widespread reptile from the data search, the closest being a 1997 grass snake record 420m to the south of Sub-area 5. LOW. There were no ponds or other water bodies in the gardens. The well managed garden area provided very limited cover or foraging opportunities for this species. There are no great crested newt records within 500m of the Sub-area, the closest being a 2006 record at Waldron Ghyll, 1.2km south of Sub-area 5. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1182 Table 11: Assessment of potential presence of invasive and protected species within Sub-area 5 of SDA 11 Species Main legislation (see Chapter 16) Reason for consideration Likelihood of occurrence breeding ponds and terrestrial sites. The Sub-area is located in a rural setting on the north-western edge of Heathfield. The Sussex countryside has an abundance of shallow ponds suitable as breeding sites. Invasive plants species Section 14 and Part II of Schedule 9 of the Wildlife and Countryside Act 1981 (as amended) There is a wide range of invasive plant species of which a number of widespread species occur in woodlands, aquatic and wetland habitats, and disturbed sites or close to settlements. As such there is potential for invasive plants to be present in the Sub-area. LOW. No evidence of invasive plant species was recorded onsite during the Phase 1 habitat survey though this does not guarantee their absence. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1183 NATURE CONSERVATION EVALUATION: SUB-AREA 5 - HOLMHURST, HIGH STREET 13.281 On the basis of the information available from the Phase 1 habitat survey, data search and review of BAPs, Sub-area 5 has been evaluated in terms of its potential for biodiversity, support of protected species and habitats, and the contribution the area makes as part of the wider landscape. A combined evaluation of the nature conservation value of the Sub-area using standard criteria developed by IEEM (2006) and selected criteria from Defra's (2006) 'Local Sites' evaluation guidance is provided in Table 12 below. 13.282 The biodiversity value of protected and BAP species within the Sub-area is a preliminary evaluation based upon the desk study records, habitat suitability and the conservation status of the species in question. It should be noted that where European Protected Species or BAP species are present on-site they may be valued at a lower level/scale where it is considered likely that populations would not be of sufficient importance to justify designation at a higher level. However, regardless of their biodiversity value, such species are still subject to national and/or European legislation. 13.283 Key aspects of relevant planning policy and legislation regarding conservation, including an explanation of species referred to as being of 'Principal Importance for the Conservation of Biodiversity', European Protected Species and BAP species and habitats, are provided in Chapters 16-18. Table 12: Combined Evaluation of the Nature Conservation Value of Sub-area 5 of SDA 11. Criteria 10 Remarks Features of International Importance Sub-area 1 is not subject to any international statutory nature conservation designations. The closest site of International Importance is Ashdown Forest designated as both a SAC and SPA, located approximately 11.5km to the north-west. Ashdown Forest is important for its lowland wet and dry heath habitats and associated bird assemblage. No heathland habitat or any supporting habitats that maintain the integrity of this designated area are present. Features of National Importance Sub-area 1 is not subject to any national nature conservation designations. It is not considered that any habitats or populations or assemblages of species within the Sub-area would meet the criteria for the designation of 10 SSSIs at an appropriate geographic level . Features of Regional (Sussex) Sub-area 5 is not subject to any non-statutory nature conservation designations. JNCC Guidelines for selection of biological SSSIs (see http://jncc.defra.gov.uk/page-2303#download). The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1184 Table 12: Combined Evaluation of the Nature Conservation Value of Sub-area 5 of SDA 11. Criteria Remarks Value Features of District (Wealden) Importance There are no ecological features present on-site of value at the district level. Features of Local (Heathfield) Importance A number of protected and UK BAP species may occur at the Sub-area, as follows: - Reptiles, including slow-worm and common lizard; - Birds such as house sparrow, starling, dunnock and song thrush; - Small mammals such as hedgehog; and - Bats, such as soprano, noctule bat and brown long eared. Based on the quality and extent of habitat present, it is considered that populations of these species would be significant at the local level. There is a single UK BAP priority habitat present on-site: hedgerow (see Habitat Map) although this habitat is limited in extent and not considered to be an outstanding example of its type and is therefore of no more than local importance. Features of Value within the immediate vicinity of the Sub-area The Sub-area is dominated by improved grassland, scattered trees and introduced shrubs which are likely to be of some value as foraging, cover and breeding sites for a range of generalist species and therefore of value in maintaining the ecology of the area. However, this is a common and widespread habitat that does not generally support rare species or diverse assemblages of species and is therefore of value in the immediate vicinity of the Sub-area. Features of Secondary and Supporting Value / Connectivity within the landscape Linear belts of scattered trees, introduced shrubs and hedgerows may provide connectivity between off-site ecological receptors such as small fields, woodland copses, hedgerows and tree lines. On-site habitats may extend the foraging and breeding range for off-site species using Sub-area 4 and 6. The Sub-area may also function as a buffer to the urban edge of Heathfield and provide a wildlife corridor and/or stepping stones for mobile species moving across the Heathfield urban-rural fringe. Social Value / Recorded History and Cultural Associations The Sub-area is privately owned and provides aesthetic and recreational value to its owners. No ancient trees were present on-site. Trees receiving TPOs are present on the southern boundary of the Subarea and provide visual amenity value. Economic value No on-site habitats/species currently provide a resource that could be exploited for their economic value. Size and extent The Sub-area measures 0.17ha (total SDA area 9.33ha) with improved grassland and planted trees/shrubs being the dominant habitat types. It therefore comprises a small number of habitat types, with potential to support a low range of common and protected species. Fragility All on-site habitats are relatively recently established, species poor, would rapidly recover from impacts and can be restored/resown. Typicalness All on-site habitats are typical of sub-urban properties and are not outstanding examples of their types. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1185 Summary of Nature Conservation Evaluation 13.284 On the basis of the above criteria, Sub-area 5 is considered to be of ecological value within the local context due to its potential to support declining and BAP species, including those protected at a National and European level i.e. reptiles and bats, although this is strongly associated with boundary habitats and features, and additionally, in the case of roosting bats, the property of Holmhurst. The legal and policy implications associated with these species are detailed in Chapter 16 and 17. 13.285 Areas of improved grassland occupy the majority of the Sub-area (95%) and in their current managed state are typically a habitat of low ecological value and therefore considered to be of value in the immediate vicinity only. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1186 GREEN INFRASTRUCTURE APPRAISAL: SUB-AREA 5 - HOLMHURST, HIGH STREET Water bodies and local catchment area 13.286 Sub-area 5 is located towards the top of the ridge, is relatively flat, no standing water was present and it did not appear to form part of the wider system that drains northward into Markly Wood. Habitat connectivity 13.287 Sub-area 5 has limited connectivity to Sub-areas 1-4, with boundary habitats providing the only potential wildlife corridors for mobile species such as bats, birds, invertebrates and mammals. Connectivity could be improved greatly by extending existing lines of scattered trees and scrub in Sub-area 4 so that they link with the northern boundary of Sub-area 5 (see enhancement section of Sub-area 4). Sustainable transport routes/PROW 13.288 Sub-area 5 is privately owned and no Public Right Of Way (PROW) is present. There is currently no network of cycle routes serving the Sub-area. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1187 CONCLUSIONS AND RECOMMENDATIONS: SUB-AREA 5 - HOLMHURST, HIGH STREET 13.289 Sub-area 5 is not subject to any statutory or non-statutory nature conservation designations, but part of the garden is located within the High Weald AONB. The nearest statutory designated site for nature conservation is Heathfield Park SSSI located 1.52km to the east of Sub-area 5. The nearest non-statutory designated nature conservation site is Oaken & Furlong Woods SNCI located 1.9km to the north-east of Sub-area 5. On the basis of information available at the time of report production, it is considered unlikely that the Sub-area performs an important supporting role for these sites based upon the type an extent of habitats present within the Sub-area, the features for which the sites are designated and the degree of connectivity between them. 13.290 Overall, Sub-area 5 of SDA 11 is considered to be of ecological value at a local level, due to its potential to support legally protected and BAP species, including those protected at a National and European level i.e. reptiles and bats. 13.291 A large percentage of the Sub-area is dominated by improved grassland which is typically a habitat of low ecological value. Areas of highest ecological value at the Subarea are associated with the house and planted trees and shrubs around its boundary. 13.292 The Sub-area may also provide a secondary and supporting role to the local network of ecological receptors surrounding it, primarily by contributing to wildlife corridors used by species moving between the urban areas of Heathfield and the wider Wealden countryside. 13.293 The following UK BAP habitats/species are or have potential to be present within the Sub-area: Reptiles, including slow-worm and common lizard; Birds such as house sparrow, starling, dunnock and song thrush; Small mammals such as hedgehog; Bats, such as soprano pipistrelle, noctule bat and brown long eared; and, Hedgerows 13.294 BAP habitats/species are not necessarily rare, but under PPS9 and the NERC Act 2006 are all of principal importance for biodiversity (ODPM, 2005) and are of material consideration in the planning process. None of the BAP habitats or populations of BAP species currently known to be present at the Sub-area are considered as notable or exceptional examples of their type. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1188 Recommended further surveys relevant to Sub-area 5 Overview 13.295 The surveys recommended below assume the loss of or damage to suitable habitat should the Sub-area be proposed for development. There is potential to avoid and/or limit impacts through habitat retention and protection (see below). The final approach to surveys will have to be based on consideration of detailed proposals for the Subarea/SDA, though in all cases published best practice should be followed with regard to survey methodology etc. 13.296 To provide a sufficient baseline of data and mitigate against any potential impact on declining, BAP and protected species/habitats at Sub-area 5, further surveys for bats are recommended. Bats 13.297 The detached house in Sub-area 5 provides a potentially suitable roosting habitat for a variety of both crevice and void dwelling bat species. This potential is increased due to the proximity of other buildings suitable for bats as well as the opportunities for roosting and foraging found within the wider landscape. 13.298 Following current guidelines (BCT, 2007) further bat surveys are recommended to assess the presence or potential presence of any bat roosts, as well as the function the Sub-area might provide for foraging and commuting. This should include a detailed building inspection of domestic premises, tree inspections of all semi-mature/mature trees within the boundary and emergence and activity surveys. Emergence and emergence surveys must be carried out between May and September. Please note that it would be advantageous to carry out these surveys in conjunction with Sub-area 6 to obtain a better understanding of bat activity at SDA 11. Outline mitigation relevant to Sub-area 5 Habitat retention and protection 13.299 The boundary features of Sub-area 5 provide the most valuable on-site habitats. Whilst they comprise a high percentage of planted non-native species they provide some connectivity with the wider landscape and are of potential value to more mobile species such as bats, bird, invertebrates and small mammals. Development proposals should seek to retain and enhance these features, where possible. 13.300 Where the loss of trees, dense shrubs and hedgerows is unavoidable it will be necessary to carry out any required protected species surveys and mitigation prior to their removal and provide compensation for their loss. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1189 13.301 All construction works taking place in the vicinity of retained semi-mature/mature trees, scrub and hedgerows should conform to British Standard 5837:2005 Trees in Relation to Construction to maintain the integrity of these habitats. Mitigation for protected species 13.302 Nesting birds: Scattered trees and dense scrub provide suitable nesting habitat for a variety of bird species. It is recommended that any vegetation clearance affecting nesting habitat should be undertaken outside of the bird nesting season which runs from March to August inclusive. 13.303 Reptiles: Due to the small area of potentially suitable habitat there is a low risk of reptiles being present. Where they are present they are likely to be restricted to the boundary features of the property. Therefore, it is recommended that boundary features are retained in any development proposals to avoid impacts. Where retention is not possible a precautionary approach may be feasible by managing edge habitats in order to make them unsuitable for reptiles. However, this approach should be reviewed prior to any development in case baseline conditions at the Sub-area have changed since the date of the survey and so that the full extent of works at the Sub-area / SDA can be considered. 13.304 Bats and lighting: While different species of bat react differently to night time lighting, research has found that bats are sensitive to artificial lighting and that excessive lighting can delay bats from emerging, thus shortening the time available for foraging, as well as causing bats to move away from suitable foraging grounds or roost sites, to alternative dark areas (Jones, 2000). 13.305 To minimise impacts on bats from lighting associated with any proposed development it will be necessary to limit light spillage and glare. This can be achieved by following accepted best practice (Institute of Ecology and Environmental Management 2006, Institute of Lighting Engineers 2007). Habitat compensation relevant to Sub-area 5 13.306 Any compensation planting should draw on best practice with regard to the use of native species of local provenance, avoidance of invasive species, and use of non-native species of known wildlife value provided in Chapter 19. Initial measures to be considered in development proposals for the Sub-area would be as follows: Replacement planting to compensate for any loss of woodland, trees, scrub, grassland etc. should be provided as an integral part of any landscape masterplanning for the Sub-area/SDA. This should aim to retain the Sub-area’s The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1190 value for any protected/UK BAP species confirmed present without recourse to off-site translocation. It should include only native species. 13.307 If development involves the removal of trees with potential to provide habitat for birds and bats then artificial bird and bat boxes should be considered in order to provide replacement nesting/roosting habitat. Habitat enhancement relevant to Sub-area 5 13.308 The following outline proposal for habitat enhancement should be considered as part of detailed proposals for development of Sub-area 5 to ensure that features of local ecological value contribute to the ecology of the District as a whole. Additional generic management recommendations for these features are provided in Chapter 19. Hedgerows 13.309 On-site hedgerows provide habitat for a range of urban species. It is recommended that the cutting of hedgerows be managed to maximise their value for wildlife (see Chapter 19). Green infrastructure enhancements relevant to Sub-area 5 13.310 Many of the recommendations for habitat protection, creation and enhancement are likely to benefit both biodiversity and green infrastructure within the District. In order to ensure these issues are adequately addressed at the Sub-area level, specific recommendations referring to issues such as off-site habitat, hydrology, access and landscape are provided below: If any proposed development comprises large areas of buildings and hardstanding the use of SuDs schemes, green roofs and walls should be considered to enhance the biodiversity value of the Sub-area, protect water quality and reduce the rate of runoff. The use of native tree and shrub planting and species of known wildlife value in landscape schemes should be considered in detailed landscape proposals as this will provide opportunities for wildlife at the smallest scale of development, ensuring that opportunities for common species are not diminished. 13.311 Further detail on measures to enhance biodiversity and green infrastructure are provided in Chapter 19. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1191 HABITAT SURVEY: SUB-AREA 6 - LAVENDER COTTAGE, HIGH STREET Overview 13.312 Sub-area 6 was surveyed on the 24th May 2011. Sub-area 6 occupies 0.19ha and comprises the property, and associated buildings and garden, of Lavender Cottage. As such, it contains the most modified habitats within the SDA. Habitats present within the Sub-area included; buildings, hardstanding, semi-improved grassland, scattered trees and introduced shrubs. Sub-area 6 is located between Sub-area 5 and the properties of Oaksdown and Lowlands. It is accessed from Heathfield High Street (A265). Hedgerows 13.313 Short sections of beech hedge were present along the western boundary. Semi-improved grassland 13.314 Grassland at the rear of the property comprised sweet vernal grass, Yorkshire fog, Timothy, white clover and creeping buttercup. The front lawn was surprisingly diverse and included either relictual acid grassland/heath species or had been formerly seeded/planted. The grasses red fescue, Yorkshire fog and common bent were abundant to frequent. Wildflowers included abundant to locally frequent mouse-ear hawkweed, selfheal, creeping buttercup, common bird’s-foot-trefoil, yarrow, violet, and cat’s-ear along with the shrubs heather and bilberry. Scattered trees and introduced shrubs 13.315 Planted trees and shrubs along the western and eastern boundary included a moderate range of standard horticultural stock. Species included: cherry laurel, rhododendron, Portuguese laurel, holly, rowan, eucalyptus and cypress. Mature pedunculate oaks were present at the very front of the property. Building 4 and hardstanding 13.316 The main section of Lavender Cottage was a large brick-built, two-storey building with wooden soffits and tiled, pitched roof. A garage and conservatory had extended the footprint on the western and eastern side. The building was, generally, in a good state of repair although gaps between the soffits and building façade were present and some tiles were missing/raised. Fauna 13.317 No fauna was observed during the Phase 1 survey. Target notes relevant to sub-area 5 13.318 No features were present that required target notes. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1192 PROTECTED SPECIES RISK ASSESSMENT: SUB-AREA 6 - LAVENDER COTTAGE, HIGH STREET 13.319 The habitats at Sub-area 6 were evaluated as to their likelihood to provide sheltering, roosting, nesting and foraging habitat for the following species/species groups: Breeding birds Bats Badgers Reptiles Great crested newt Invasive plant species 13.320 These species were selected for further consideration because the results of the desk study revealed that they occur in the vicinity of the SDA and potentially suitable habitat is present within Sub-area 6. The results of the field survey, combined with information from the desk study, are presented in Table 13 below. The relevant legislation and policies relating to protected species is presented within Chapter 16 and 17. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1193 Table 13: Assessment of potential presence of invasive and protected species within Sub-area 6 of SDA 11 Species Main legislation (see Chapter 16) Breeding birds Wildlife and Countryside Act 1981 (as amended) - selected species Schedules 1 and 8.

The Conservation of Habitats and Species Regulations 2010 - Schedule Reason for consideration Likelihood of occurrence Scattered trees, scrub, introduced shrubs and hedgerows provide suitable breeding habitat. Surrounding rural landscape to the north may also provide an important foraging resource. Mature/semi-mature scattered trees provide suitable roosting habitat. Boundary features of hedges and tree lines provide suitable foraging and commuting habitat. Any building, but particularly those of early or pre twentieth century construction can provide suitable roosting areas for both void and crevice dwelling species. Widespread and wide-ranging species, especially in the Sussex and the south-east of the UK. Badgers are known to regularly exploit domestic gardens on the urban fringe. Domestic gardens can contain suitable habitat features such as compost piles and fire wood stacks that can be exploited by reptile species. Slow worms are often associated with domestic gardens. Hedgerows and gardens cam provide suitable cover and foraging opportunities for this species. Two ponds are identified within a 500m radius, which is the guideline HIGH. Scattered trees, dense shrubs and hedgerows are likely to provide a foraging and nesting resource for common species of bird, although the extent of suitable habitat was limited. Parts of the house, such as wooden soffits, may also provide suitable habitat for urban species such as house sparrow. 65 species recorded within a 2km radius of the SDA. HIGH (roosting) MEDIUM (foraging). Despite the relatively small and discrete size of this Sub-area, the residential building has some potential for a roost as it provides features such as complex roof structures with voids and missing/raised tiles. Back gardens are often used by bats for foraging due to the higher diversity/density of flying invertebrates that may utilise well planted (diverse) ornamental schemes (as present on-site). Seven bat species are recorded within a 2km radius of SDA 11 including a Natterer’s hibernation roost 100m east of Sub-area 6. NEGLIGIBLE. Although domestic gardens are regularly used by badgers no signs of use were observed during the survey and there was limited cover that could have obscured a sett. Badger records are not provided as part of the SxBRC data search. LOW. The garden located in Sub-area 6 is managed and the lawn regularly mown. Opportunities for species such as slow worms were limited to less intensively managed edge habitats. There are off-site records for all four species of widespread reptile from the data search, the closest being a 1997 grass snake record 420m to the south of Sub-area 6. LOW. There were no ponds or other water bodies in the gardens. The well managed garden area provided very limited cover or foraging opportunities for this species. There are no records within 500m of the Sub-area, the closest being a 2006 record at Waldron Ghyll, 1.2km south of Sub-area 6. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1194 Table 13: Assessment of potential presence of invasive and protected species within Sub-area 6 of SDA 11 Species Main legislation (see Chapter 16) 2. Invasive plant species Section 14 and Part II of Schedule 9 of the Wildlife and Countryside Act 1981 (as amended) Reason for consideration distance (English Nature, 2001) which great crested newt may commute between breeding ponds and terrestrial sites. The Sub-area is located in a rural setting on the north-western edge of Heathfield. The Sussex countryside has an abundance of shallow ponds suitable as breeding sites. There is a wide range of invasive plant species of which a number of widespread species occur in woodlands, aquatic and wetland habitats, and disturbed sites or close to settlements. As such there is potential for invasive plants to be present in the Sub-area. Likelihood of occurrence LOW. No evidence of invasive plant species was recorded on-site during the Phase 1 habitat survey though this does not guarantee their absence. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1195 NATURE CONSERVATION EVALUATION: SUB-AREA 6 - LAVENDER COTTAGE, HIGH STREET 13.321 On the basis of the information available from the Phase 1 habitat survey, data search and review of BAPs, Sub-area 6 has been evaluated in terms of its potential for biodiversity, support of protected species and habitats, and the contribution the area makes as part of the wider landscape. A combined evaluation of the nature conservation value of the Sub-area using standard criteria developed by IEEM (2006) and selected criteria from Defra's (2006) 'Local Sites' evaluation guidance is provided in Table 14 below. 13.322 The biodiversity value of protected and BAP species within the Sub-area is a preliminary evaluation based upon the desk study records, habitat suitability and the conservation status of the species in question. It should be noted that where European Protected Species or BAP species are present on-site they may be valued at a lower level/scale where it is considered likely that populations would not be of sufficient importance to justify designation at a higher level. However, regardless of their biodiversity value, such species are still subject to national and/or European legislation. 13.323 Key aspects of relevant planning policy and legislation regarding conservation, including an explanation of species referred to as being of 'Principal Importance for the Conservation of Biodiversity', European Protected Species and BAP species and habitats, are provided in Chapters 16-18. Table 14: Combined Evaluation of the Nature Conservation Value of Sub-area 6 of SDA 11. Criteria Remarks Features of International Importance Sub-area 6 is not subject to any international statutory nature conservation designations. The closest site of International Importance is Ashdown Forest designated as both a SAC and SPA, located approximately 11.5km to the north-west. Ashdown Forest is important for its lowland wet and dry heath habitats and associated bird assemblage. No heathland habitat or any supporting habitats that maintain the integrity of this designated area are present. Features of National Importance Sub-area 6 is not subject to any national nature conservation designations. The Sub-area has potential to support a number of UK BAP priority species. While BAP habitats occur and populations of BAP species may be present, it is not considered that any would be nationally important examples of their type. Features of Regional (Sussex) Value Sub-area 6 is not subject to any non-statutory nature conservation designations. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1196 Table 14: Combined Evaluation of the Nature Conservation Value of Sub-area 6 of SDA 11. Criteria Remarks Features of District (Wealden) Importance There are no ecological features present on-site of value at the district level. Features of Local (Heathfield) Importance A number of protected and UK BAP species may occur at the Sub-area, as follows: - Reptiles, including slow-worm and common lizard; - Birds such as house sparrow, starling, dunnock and song thrush; - Small mammals such as hedgehog; and - Bats, such as soprano, noctule bat and brown long eared. Based on the quality and extent of habitat present, it is considered that populations of these species would be significant at the local level. There is a single UK BAP priority habitat present on-site: hedgerow (see Habitat Map) although this habitat is limited in extent and not considered to be an outstanding example of its type and is therefore of no more than local importance. A small area of semi-improved acid grassland was present, but was very limited in extent, not an outstanding example of its type and may have been formerly planted. It is therefore considered to be of no more than local importance. Features of Value within the immediate vicinity of the Sub-area The Sub-area is dominated by semi-improved grassland, scattered trees and introduced shrubs which are likely to be of some value as foraging, cover and breeding sites for a range of generalist species and therefore of value in maintaining the ecology of the area. However this is a common and widespread habitat that does not generally support rare species or diverse assemblages of species and is therefore of value in the immediate vicinity of the Sub-area. Features of Secondary and Supporting Value / Connectivity within the landscape Linear belts of scattered trees, introduced shrubs and hedgerows may provide connectivity between off-site ecological receptors such as small fields, woodland copses, hedgerows and tree lines. On-site habitats may extend the foraging and breeding range for off-site species using Sub-area 4 and 5. The Sub-area may also function as a buffer to the urban edge of Heathfield and provide a wildlife corridor and/or stepping stones for mobile species moving across the Heathfield urban-rural fringe. Social Value / Recorded History and Cultural Associations The Sub-area is privately owned and provides aesthetic and recreational value to its owners. No ancient trees were present on-site. No trees receiving TPOs are present on-site or adjacent to its boundary, although TPOs are present on the southern boundary of Sub-area 5. Economic value No on-site habitats/species currently provide a resource that could be exploited for their economic value. Size and extent The Sub-area measures 0.19ha (total SDA area 9.33ha) with semiimproved grassland and planted trees/shrubs occupying approximately 90% of the Sub-area. It therefore comprises a small number of habitat types, with potential to support a low range of common and protected species. Buildings and hardstanding occupy the remaining area. Fragility All on-site habitats are relatively recently established, species poor, The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1197 Table 14: Combined Evaluation of the Nature Conservation Value of Sub-area 6 of SDA 11. Criteria Remarks would rapidly recover from impacts and can be restored/resown. Typicalness All on-site habitats are typical of suburban properties and are not outstanding examples of their types. Summary of Nature Conservation Evaluation 13.324 On the basis of the above criteria, Sub-area 6 is considered to be of ecological value within the local context due to the presence of a small area of semi-improved acid grassland and the Sub-area’s potential to support declining and BAP species, including those protected at a National and European level i.e. reptiles and bats. However, this potential is strongly associated with boundary habitats and features, and additionally, in the case of roosting bats, the property of Lavender Cottage. The legal and policy implications associated with these species are detailed in Chapter 16 and 17. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1198 GREEN INFRASTRUCTURE APPRAISAL: SUB-AREA 6 - LAVENDER COTTAGE, HIGH STREET Water bodies and local catchment area 13.325 Sub-area 6 is located towards the top of a ridge, is relatively flat, no standing water was present and it did not appear to form part of the wider system that drains northward into Markly Wood. Habitat connectivity 13.326 Markly Wood encapsulates the west, north and eastern boundaries of SDA 11 with Subareas 1 - 4 being well connected to the larger woodland complex located to the north and west of Heathfield. Sub-area 6 has limited connectivity to Sub-areas 1-4, with boundary habitats providing the only potential wildlife corridors for mobile species such as bats, birds, invertebrates and mammals. Connectivity could be improved greatly by extending existing lines of scattered trees and scrub in Sub-area 4 so that they link with the northern boundary of Sub-area 6 (see enhancement section of Sub-area 4). Sustainable transport routes/PROW 13.327 Sub-area 6 is privately owned and no Public Right Of Way (PROW) is present. There is currently no network of cycle routes serving the Sub-area. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1199 CONCLUSIONS AND RECOMMENDATIONS: SUB-AREA 6 - LAVENDER COTTAGE, HIGH STREET 13.328 Sub-area 6 is not subject to any statutory or non-statutory nature conservation designations, but part of the garden is located within the High Weald AONB. The nearest statutorily designated site for nature conservation is Heathfield Park SSSI located 1.5km to the east of Sub-area 6. The nearest non-statutory designated nature conservation site is Oaken & Furlong Woods SNCI located 1.9km to the north-east of Sub-area 6. On the basis of information available at the time of report production, it is considered unlikely that the Sub-area performs an important supporting role for these sites based upon the type and extent of habitats present with the Sub-area, the features for which the sites are designated and the degree of connectivity between them. 13.329 Overall, Sub-area 6 of SDA 11 is considered to be of ecological value at a local level, due to the presence of a small area of semi-improved acid grassland and the Sub-area’s potential to support legally protected and BAP species, including those protected at a National and European level i.e. reptiles and bats. 13.330 The Sub-area may also provide a secondary and supporting role to the local network of ecological receptors surrounding it, primarily by contributing to wildlife corridors used by species moving between the urban areas of Heathfield and the wider Wealden countryside. 13.331 The following UK BAP habitats/species are or have potential to be present within the Sub-area: Reptiles, including slow-worm and common lizard; Birds such as house sparrow, starling, dunnock and song thrush; Small mammals such as hedgehog; Bats, such as soprano pipistrelle, noctule bat and brown long eared; and Hedgerow. 13.332 BAP habitats/species are not necessarily rare but under PPS9 and the NERC Act 2006 are all of principal importance for biodiversity (ODPM, 2005) and are of material consideration in the planning process. None of the BAP habitats or populations of BAP species currently known to be present at the Sub-area are considered as notable or exceptional examples of their type. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1200 Recommended further surveys relevant to Sub-area 6 Overview 13.333 The surveys recommended below assume the loss of or damage to suitable habitat should the Sub-area be proposed for development. There is potential to avoid and/or limit impacts through habitat retention and protection (see below). The final approach to surveys will have to be based on consideration of detailed proposals for the Subarea/SDA, though in all cases published best practice should be followed with regard to survey methodology etc. 13.334 To provide a sufficient baseline of data and mitigate against any potential impact on declining, BAP and protected species/habitats at Sub-area 6, further surveys for bats are recommended. Bats 13.335 Lavender Cottage provides a suitable roosting habitat for a variety of both crevice and void dwelling bat species. The potential for a roost is increased due to the proximity of other buildings suitable for a roost as well as the opportunities for roosting and foraging found within the wider landscape. 13.336 Following current guidelines (BCT, 2007) further bat surveys are recommended to assess the presence or potential presence of any bat roosts, as well as the function the Sub-area might provide for foraging and commuting. This should include a detailed building inspection of domestic premises, tree inspections of all semi-mature/mature trees within the boundary and emergence and activity surveys. Emergence and activity surveys must be carried out between May and September. Please note that it would be advantageous to carry out these surveys in conjunction with Sub-area 5 to obtain a better understanding of bat activity at SDA 11. Outline mitigation relevant to Sub-area 6 Habitat retention and protection 13.337 Sub-area 6 boundary features provide the most valuable on-site habitats. Whilst they comprise a high percentage of planted non-native species they provide some connectivity with the wider landscape and are of potential value to more mobile species such as bats, bird, invertebrates and small mammals. Development proposals should seek to retain and enhance these features, where possible. 13.338 Where the loss of trees, dense shrubs and hedgerows is unavoidable it will be necessary to carry out any required protected species surveys and mitigation prior to their removal and provide compensation for their loss. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1201 13.339 All construction works taking place in the vicinity of retained semi-mature/mature trees, scrub and hedgerows should conform to British Standard 5837:2005 Trees in Relation to Construction to maintain the integrity of these habitats. Mitigation for protected species 13.340 Nesting birds: Woodland edge, scattered trees and dense scrub provide suitable nesting habitat for a variety of bird species. It is recommended that any vegetation clearance affecting nesting habitat should be undertaken outside of the bird nesting season which runs from March to August inclusive. 13.341 Reptiles: Due to the small area of potentially suitable habitat there is a low risk of reptiles being present. Where they are present they are likely to be restricted to the boundary features of the property. It is therefore recommended that boundary features are retained in any development proposals to avoid impacts. Where retention is not possible a precautionary approach may be feasible by managing edge habitats in order to make them unsuitable for reptiles. However, this approach should be reviewed prior to any development in case baseline conditions at the Sub-area have changed since the date of the survey and so that the full extent of works at the Sub-area/SDA can be considered. 13.342 Bats and lighting: While different species of bat react differently to night time lighting, research has found that bats are sensitive to artificial lighting and that excessive lighting can delay bats from emerging, thus shortening the time available for foraging, as well as causing bats to move away from suitable foraging grounds or roost sites, to alternative dark areas (Jones, 2000). 13.343 To minimise indirect impacts from lighting associated with development it will be necessary to limit night time spillage and glare. This can be achieved by following accepted best practice (Institute of Ecology and Environmental Management 2006, Institute of Lighting Engineers 2007). Habitat compensation relevant to Sub-area 6 13.344 Any compensation planting should draw on best practice with regard to the use of native species of local provenance, avoidance of invasive species, and use of non-native species of known wildlife value provided in Chapter 19. Initial measures to be considered in development proposals for the Sub-area are as follows: Replacement planting to compensate for any loss of woodland, trees, scrub, grassland etc. should be provided as an integral part of any landscape masterplanning for the Sub-area. This should aim to retain the Sub-area’s value for The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1202 any protected/UK BAP species confirmed present without recourse to off-site translocation. It should include only native species. If development involves the removal of trees with potential to provide habitat for birds and bats then artificial bird and bat boxes should be considered in order to provide replacement nesting/roosting habitat. Habitat enhancement relevant to Sub-area 6 13.345 The following outline proposals for habitat enhancement should be considered as part of detailed proposals for development of Sub-area 6 to ensure that features of local ecological value contribute to the ecology of the District as a whole. Additional generic management recommendations for these features are provided in Chapter 19. Hedgerows 13.346 On-site hedgerows provide habitat for a range of urban species. It is recommended that the cutting of hedgerows be managed to maximise their value for wildlife (see Chapter 19). Green infrastructure enhancements relevant to Sub-area 6 13.347 Many of the recommendations for habitat protection, creation and enhancement are likely to benefit both biodiversity and green infrastructure within the District. In order to ensure these issues are adequately addressed at the Sub-area level, specific recommendations referring to issues such as off-site habitat, hydrology, access and landscape are provided below: If any proposed development comprises large areas of buildings and hardstanding the use of SuDs schemes, green roofs and walls should be considered to enhance the biodiversity value of the Sub-area, protect water quality and reduce the rate of runoff. The use of native tree and shrub planting and species of known wildlife value in landscape schemes should be considered in detailed landscape proposals as this will provide opportunities for wildlife at the smallest scale of development, ensuring that opportunities for common species are not diminished. 13.348 Further detail on measures to enhance biodiversity and green infrastructure are provided in Chapter 19. The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1203 PLANNING POLICY SUMMARY FOR SDA 11 13.349 It is considered that a number of regional and local planning policies are relevant to SDA 11. Table 15 below provides a summary of those policies, and identifies the Subareas which they are applicable to. Please note, however, that this is not an exhaustive list and other policies may or may not be applicable to the Sub-areas. This may include existing policies or policies that will form part of the Council's LDF. The full text of relevant policies is contained in Chapter 18 and this should be referred to. Relevant regional and local planning policy includes those from the following: Wealden District Council’s Adopted Local Plan (1998) Wealden District Council’s Non-statutory Local Plan (2005) The South East Plan (2009) Wealden District Council's Submission Core Strategy (2011) The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1204 Table 15: Regional and local planning polices relevant to SDA 11 and Sub-areas 1 - 6.

Appropriate measures are required to protect, manage and enhance the site's nature conservation interest, or to provide a replacement habitat, where the proposal has implications for other wildlife habitats. Woodland, trees and hedgerows considered worthy of retention, unless the need for development outweighs nature conservation or amenity value, should be retained. Any loss should be replaced on or near the site. Ancient Woodland should be retained and ecology, landscape and historic value should not be prejudiced by the proposal. Existing pedestrian, cycle or bridleway routes are protected, unless alternative provision is made, which would be equally convenient, safe and attractive for users. Proposals should ensure that the necessary infrastructure to meet the needs of the development is available or provided at an appropriate time. 1 2 3 4 5 6 CS2 Water Supply Proposals must not present an unacceptable risk to water resources.

Geographically speaking, these habitats are strongly associated with individual Sub-areas. Unimproved and semi-improved habitats are concentrated in the western half of the SDA i.e. Sub-areas 1-3 and improved habitats are concentrated in Sub-areas 4-6 in the east. 13.351 Overall, on the basis of the results of the Phase 1 habitat survey and protected species assessment, the SDA is judged to be of ecological value of at least a district level. Woodland, and mosaics of acid/marshy grassland, represent the most ecologically important features of the SDA and there should be presumption that these habitats will be retained and protected except where loss is unavoidable and only after any necessary protected species surveys and mitigation have taken place. Where housing allocation allows, it is recommended that development of Sub-areas 1 to 3 be avoided completely. Green Infrastructure 13.352 The SDA is situated on the north side of a ridge and is approximately 150m O.D. at its highest point i.e. along its southern limit. It then slopes northwards to approximately 115m O.D. 13.353 Ghyll woodland is present within Sub-area 3, is contiguous with the northern boundary of Sub-area 2 and the north-eastern boundary of Sub-area 4 and is adjacent to the eastern corner of Sub-area 1. In addition to ghyll woodland, wet flushes/springs (associated with marshy grassland) are present in Sub-areas 1, 2 and 3 and ditches are present in Subarea 4. All of these features feed into the main ghyll system. SDA 11 therefore forms part of the upper catchment area that drains northwards to feed into the River Rother and as such the off-site hydrogeological impacts of any development proposals should be considered in sufficient detail to establish likely impacts on these sensitive habitats. 13.354 Markly Wood encapsulates the west, north and eastern boundary of SDA 11 and consequently Sub-areas 1 to 4 are well connected to the larger woodland complex located to the north and west of Heathfield, via on-site ghylls, woodland, scattered trees and scrub and lines of mature trees (likely to be former hedgerows). These provide wildlife corridors for a range of mobile species such as bats, birds, invertebrates and mammals. 13.355 Consideration should be given to maintaining the existing network of woodland through the retention (and enhancement) of broad-leaved semi-natural woodland in Sub-area 1, The Ecology Consultancy Strategic Sites Ecological Assessment / Report for Wealden District Council 1210 mixed woodland in Sub-area 3 and linear belts of trees and scrub along old field boundaries, particularly where they are orientated north to south across SDA 11. 13.356 Following Natural England’s Standing Advice on Ancient Woodland (2011a) a minimum buffer of at least 15m in width should be maintained between ancient woodland and any development boundary. It is recommended that this buffer zone also be applied to sections of adjacent broad-leaved deciduous and ghyll woodland across the SDA including those not designated as ancient woodland viz. the section contiguous with the northern boundary of Sub-area 2 and 4. 13.357 Sub-areas 2 to 4 are within and Sub-area 1 is adjacent to Heathfield Habitat Link BOA. Any development proposals should consider the BOA targets which seeks to sympathetically manage the habitat mosaic present in the area and increase the ‘permeability’ of the landscape for wildlife. Further surveys 13.358 A range of further surveys for rare, BAP and protected species are recommended for Sub-areas 1-6. These should be completed prior to the start of Sub-area preparation works. If these species are found on the Sub-areas, specific mitigation measures, possibly including the development of method statements, translocation to off-site receptor sites and/or the application for EPSM licenses may be required to comply with planning policy and nature conservation legislation. A summary of planning policy and legislation is included as Chapter 16 and 17. A summary of recommended surveys is provided in Table 16 below.
