THE NATURAL ENVIRONMENT OF LANE COVE BY LYNNE McLOUGHLIN WITH PLANT SURVEYS BY VAN KLAPHAKE The Natural Environment of Lane Cove ACKNOWLEDGMENTS I wish to thank those people who have so willingly assisted in assembling materials and information for various parts of this book detailing the natural environment of Lane Cove. In particular, I wish to thank Susan Butler, Lane Cove Council Bushland Management Officer, for her great support and encouragement for the project from its inception as environmental education material, through the production of the Teachers’ Guide, to its present form. Susan also produced all the maps, assisted with illustrative material, co-ordinated the production of the listings for the appendices and acted as editor for both the Teachers’ Guide and this publication. Special thanks are due to Van Klaphake who surveyed, identified and listed the plant species of our bushland reserves, assisted by Sandy Coe. Van also drafted the vegetation maps, contributed to the birds and the animals listings and assisted with the mushrooms listing. Thanks also to Jon Kingston and Simon Pitcher for their painstaking work in preparing the listings for the extensive appendices. Assistance was also much appreciated from Sheila Walkerden, for information and listings on birds, John Diversi, for listings and information on reptiles and Dennis Ormsby, for material on mammals.

INTRODUCTION Lane Cove is a relatively small municipality of 1,056 hectares on the Lower North Shore (Map 1), almost completely contained within the catchment of the Lane Cove River (the east side of Greenwich drains to Berrys Creek and the Parramatta River). It is bounded on the east by the Pacific Highway, also the eastern edge of the catchment, and on the west and south by the river itself. Mowbray Road serves as the boundary to the north. 163 hectares of the total area is zoned as Open Space, of which 74 hectares is classified as bushland (Map 2), as at 1989 (some areas have been added to public open space since). This represents only 7% of the Municipality and less than half of the total open space. Thus it is a very precious resource, fortunately at present augmented by further bushland areas in public or private ownership which are not zoned as open space. Many residents who live on the edge of reserves maintain parts of their property close to the bush in a natural state, increasing total bushland and wildlife habitat. This volume is a direct off-shoot of a previous publication specifically designed for educational use. In 1991, Lane Cove Council, with the assistance of the Department of Planning’s Metropolitan Greenspace Program, produced an Environmental Education Package for Lane Cove schools. This Package was designed to assist teachers, particularly at primary level, interpret the natural environment of their local area. It consisted of a variety of readily available resource materials such as books, posters, leaflets and videos and was accompanied by a specially written Teachers’ Guide. 5 The Natural Environment of Lane Cove The Natural Environment of Lane Cove: A Teachers’ Guide provided background information on each element of the local natural environment, as well as student activities and worksheets on each topic, tree lists and a map for each school site, other plant lists and a bird list. The production of such a comprehensive set of materials for classroom use and provision of these packages to local schools was a pioneering initiative for local government in promoting awareness of the local environment amongst its children. Lane Cove Council has been committed to bushland preservation and protection for over 20 years. Their commitment to this project thus reflects a long history of concern for the natural environment of Lane Cove. Council believed it important that the children of Lane Cove both understand and appreciate their local environment. Whilst the importance of environmental education in schools had been recognised in the 1989 Environmental Education Curriculum document, there was a significant shortage of locally based information and materials for teachers to translate this document into meaningful local experiences for children. The Environmental Education package was designed to meet this need. However, it soon became obvious that the information about Lane Cove’s natural environment contained in the Teachers’ Guide should be more readily available. This present volume represents the information component of the Teachers’ Guide, with the addition of detailed reference listings on the plants, animals, birds and fish of the municipality to further extend its value as an information base for general use. For more detailed information on each area covered, consult the references for each chapter listed before the Appendices. For the existence of such a wealth of collected data specific to the Lane Cove environment we owe a debt of gratitude to people who, over the years, have been so interested in the area as to collect a variety of information allowing us now a wide view of its natural components. We thus appreciate the work of people such as Tom Dixon of St Ignatius College, who encouraged their birdwatchers and compiled years of their data, Van Klaphake who has worked in our bushland for many years acquiring detailed knowledge of its plants and animals, bush regenerators who have lived in Lane Cove observing and caring for our bush, and researchers at Macquarie University and elsewhere who have built up knowledge of the river and its aquatic life. The major gap remaining in our knowledge is that we lack a true picture of the state of our animal populations, particularly our mammals. Thus this is an important area for future study. 6 Introduction 7 The Natural Environment of Lane Cove 2. THE BARE ESSENTIALS This chapter outlines the main features of the non-living, or inorganic, part of the natural environment of Lane Cove which provides the framework for its plants, animals, birds and insects and which has heavily influenced the way they have evolved. 2.1 Climate Sydney is located on the east coast of the continent, in a temperate zone (between the tropics and the colder sub-arctic regions). This means it experiences moderate temperatures year round and moderate year round rainfall from moisture laden winds blowing onshore from the Pacific Ocean. The climate of Lane Cove is similar to that of general metropolitan Sydney. This records an average rainfall of more than 1200mm, the wettest months being January to July, with less rainfall in late winter and spring. Extremes of temperature are infrequent: average maximum summer temperature is around 24°C and the average minimum 18°C Average winter temperatures are: maximum 16°C, minimum 7°C. However, the municipality generally slopes to the south and west from its boundary on the Pacific Highway ridge. It is thus exposed to weather which comes into Sydney from the south and west: the cold southerlies and westerlies in winter and the hot, dry westerlies and ‘southerly busters’ in summer. Yet, in any area where there are variations in topography of hills and valleys, there are significant differences in aspect and resulting microclimate. Protected valleys have more moderate temperatures than exposed ridges, south facing slopes are cooler and moister than north facing slopes, west facing slopes are drier as well as colder in winter, hotter in summer than east facing slopes. 2.2 Topography The municipality consists of a series of alternating ridges and creek valleys in the lower Lane Cove River Valley. Its eastern boundary, the north-south tending ridgeline of the Pacific Highway, is the edge of the Lane Cove River catchment and the highest part of the municipality (90-100m above sea level). From here the land slopes west and south to the river which forms the western and southern boundary. Tributary creeks have cut into the sides of the main river valley to form the series of often steep-sided ridges and valleys which run from the Pacific Highway ridge down to the river, illustrated opposite on Map 3. Above Figtree Bridge, Stringybark Creek and the former Stoney Creek (in the valley which Blackman Park now occupies) flow directly into the river. Below Figtree Bridge the shoreline is much more deeply indented with bays into which the creeks drain ie. Tannery Creek into Bums Bay, Tambourine Creek into Tambourine Bay, Gore Creek into a little bay next to Woodford Bay and Berrys Creek into Gore Cove. All the bays along this part of the river are, like the many other bays around Sydney Harbour, the result of flooding of the lower parts of the tributary creeks when the sea level rose after the last ice age. The spurs between were then left jutting out into the river as peninsulas. 2.3 Geology and Soils The Lane Cove River has carved its valley into the extensive plateau on the northern side of Sydney Harbour, known as the Hornsby Plateau. The Lane Cove, along with Middle Harbour to the east and Berowra Creek and Cowan Creek to the north, and all their tributary creeks, have left little of the original flat plateau surface. Only the ridges which now form the divides between these river systems survive. The Hornsby Plateau is made up of a series of almost horizontal layers of sedimentary rock formations, mainly of sandstones and shales. These layers are slightly tipped on an angle sloping downwards from the coast inland. The lowest layers of the plateau observable at the surface are the Narrabeen series of sandstones but they are only visible at the coast before dipping underground. 8 The Bare Essentials 9 The Natural Environment of Lane Cove Above the Narrabeen sandstones is a thick layer of Hawkesbury sandstones. The topmost, and thinnest, layer is Wianamatta shales, much like the icing on the cake of the bulk of Hawkesbury sandstones. However, as the rivers and creeks have cut deeply and widely into the plateau, there is little of the ‘icing’ left. Thus the shales are found only on the ridge tops while the sandstone is found on the valley slopes down to the creeks and rivers, as shown on Map 4. In the process of cutting their valleys, these creeks have often left spectacular cliffs and outcrops in the sandstone, one of the distinctive features of Sydney’s northside scenery. The two major rock types in Lane Cove, sandstone and shale, give rise to distinctly different types of soils. Sandstones produce sandy, stony soils which do not hold water or nutrients well and dry out easily. As these soils are on the slopes they also tend to be shallow where rain washes the material further down the slope. Sandstones are also associated with more rugged topography: steep slopes, cliffs and rock outcrops at the surface. Such topography results from the way sandstone on valley slopes both is undercut by water which seeps to the base of the rock layer, and weathers vertically along joint lines in the rock, eventually breaking away in large chunks along these vertical joint lines. Shale produces deeper and more fertile clay soils, which also hold water more easily. Being also on the flatter land of the ridges, these were the soils first used by farmers on the North Shore. As shale weathers and breaks down more evenly, the topography associated with the shales is marked by smoother, less steep slopes on the valley sides, and an almost flat grade on the ridges. Where elements of the two rock types mix, a more intermediate soil is present. This soil is stony but deeper than the sandstone soils and a little more fertile. It can occur where there are alternating beds of sandstone and shale in a transition zone between the Hawkesbury Sandstone and the Wianamatta Shale or where the clay soils from the ridge have moved downslope to sandstone areas. The cross-section below illustrates the changes in soils and topography which occur with differences in the underlying geology. A comparison of Maps 4 and 5 also reveals the clear relationships between geology and soils. There are pockets of different soils. On the flatter areas along the Lane Cove River north of Figtree Bridge and along some of the creeks are alluvial soils (sediments deposited by the river). In addition, a number of areas no longer have natural soils evident as they have been filled eg. Blackman Park, Burns Bay Reserve, Gore Creek Reserve and the golf course. 10 The Value of Bushland 3. THE VALUE OF BUSHLAND 3.1 General Values of Urban Bushland All urban bushland (bushland in, or adjacent to, urban areas) is important for a variety of reasons outlined below (adapted from National Trust, 1988). Lane Cove bushland also has some special values, discussed later. Scenic Heritage The Australian bushland has special characteristics of colour, smell, texture which give it a uniquely Australian quality. The Australian natural landscape is distinctive and recognisable and part of our natural and cultural heritage. Scientific Values The Australian landscape is ancient and complex and its scientific values barely researched. The topography of the Sydney Basin is very varied and consequently it supports a remarkable range of flora and fauna. Rare plants and animals still exist in the bushland scattered though the city. The geological history of the urban area may also be illustrated in its bushland remnants. At the very least, the original rocks and soils of the area can be seen in the bushland. It may also contain volcanic intrusions, craters, caves, rock weathering formations, cliffs and features such as monoclines. Rock formations and their different soils also contribute to the enormous variety in vegetation. Historic Landscape The natural history of an urban area is exemplified by its remaining native flora and flora. The different combinations of individual plants within each locality are the result of thousands of years of evolution and adaptation to the characteristics and conditions of that area. The remnants are all that is left to show us what existed in our suburbs prior to European settlement. Local urban bushland also has considerable archaeological importance. It contains artefacts and relics which may vividly illustrate the occupation of the area over centuries. The bushland is a vital link with generations of the original inhabitants, the Australian Aborigines, and their way of life. As written accounts were not kept by the Aborigines, middens, rock shelters, axe-grinding grooves, rock engravings and paintings in remaining bushland are all that may survive of the period prior to 1788. Urban bushland can also contain evidence of early European settlement with stone roadways, walls, bridges, wells and steps often being revealed when weeds (which invaded these areas after abandonment) are cleared. Other aspects of cultural history found in bushland are tree stumps left from logging operations, remains of early homesteads, terracing, old dams and even abandoned tools. Wildlife Corridors and Habitat The range of vegetation strata (levels from ground cover to tree canopy) in bushland provides important wildlife habitat. Many species of birds and animals arc able to survive ncar, and even in, our suburbs only because of the shelter and food provided by the native vegetation. Urban bushland also acts as wildlife corridors allowing migrating species to ‘filter through’ large cities. Even a small area of bushland may be an important link in the chain of bushland reserves forming a wildlife corridor. Narrow foreshore reserves often serve such a purpose, as well as providing roosting and nesting sites for waterbirds. 11 The Natural Environment of Lane Cove ‘Green Space’ Much of our urban bushland exists as remnant ‘fingers’ along the valleys where it was once too difficult to build. These fingers are now important as open space areas which separate identifiable suburbs and bring the natural environment close to many people. Even weed infested, degraded bushland can serve this purpose and be valued by local residents. Yet residents and local Councils arc recognising the value of good quality bushland with Councils now prepared to devote increasing funds to bush regeneration work. Bushland also makes the urban environment more pleasant by modifying air temperatures, wind velocity and air pollution levels. It holds the soil and absorbs the rain thus reducing the speed and volume of stormwater run-off and consequent problems of flooding, It can act as a screen between residential and industrial areas and help reduce noise levels eg. along busy roads. Education Resource Over 80% of the people of NSW lives in urban areas, particularly in the cities of Newcastle, Sydney and Wollongong. Small natural areas in these highly built up areas are an important education resource from preschool to tertiary level. The bushland provides for fieldwork in the natural sciences as well for outdoor activity programmes in physical and personal development. Local urban bushland also has high educational values for the general public. Natural areas within our cities provide experiences not available to most urban dwellers throughout the world. An understanding of the ‘natural’ world developed by urban dwellers in their own local environment helps develop appreciation and respect for national parks, nature reserves and other areas of high conservation value throughout the country. Recreation Resource Bushland areas, depending on their size, can provide for a variety of recreational activities from the more ‘passive’ to the very ‘active’. Children have traditionally loved the opportunities for exploration, adventure and creative games provided by their local bush. Adults can enjoy bird-watching, bushwalking, picnicking, rock-climbing, abseiling and orienteering. Bushwalking, in particular, is becoming increasingly popular with state and local governments devoting funds to the development of walking tracks, and schools adopting it as a sporting activity. 3.2 State Policy on Bushland Prior to 1986 there was no recognition of bushland as an urban land use in its own right. Land was zoned as ‘open space’ but this gave no protection to bushland as it included playing fields, ovals and developed parks. Bush could be cleared for such purposes while remaining open space. Bushland conservation groups lobbied for some years to have urban bushland areas separately recognised and protected. For example, the Union of Lane Cove Valley Conservationists (an umbrella group for all the locally based conservation groups in the Lane Cove Valley) drafted a Regional Environmental Planning Policy aimed at protection of the bushland of the Lane Cove Valley, which was submitted to the then Department of Environment and Planning. In 1986 the State Government officially recognised the values of the urban bushland of all areas in a State Environmental Planning Policy (SEPP). SEPP 19 – Bushland in Urban Areas, gazetted October, 1986, is aimed at preserving the quality of those areas of bushland reserved for public open space. It demands that councils carefully consider the environmental impact of development proposals affecting urban bushland areas and provides that no further areas of bushland reserved for public open space should be alienated to other uses. 3.3 Special Values of Lane Cove Bushland The bushland of Lane Cove holds all the general values, although some, such as the recreation activities, are limited due to the small size of the reserves. Its fingers separate and define the various parts of Lane Cove and bring the bush close to many residents. It is certainly habitat for the remaining wildlife and provides links, especially along the river, to the bigger chunks of bushland further up the Lane Cove Valley. If used 12 The Value of Bushland wisely, it can be an important educational resource for local schools and an exciting place to explore for local children. Historically, our bush contains remnants of both Aboriginal and European settlement. There are caves and rock overhangs around the shoreline once used by the Aborigines for shelter, often with middens nearby. We also have some paintings and.carvings in our reserve areas. Of European settlement there are remnants in a number of reserves. There are terracing and stone steps in different parts of Tennyson Park. The dam on Stringybark Creek was constructed late last century and the channelling of the entrance to the creek created early this century for the paper mills located here on the creek. In Tambourine Bay Park there is a well, once important for the whole district, and there are ruts worn in the rock by the iron wheels of bullock carts in Gore Creek Reserve. Convict chains were still in Gore Creek Reserve until the 1940’s and pottery fragments are often found. Large remnants discovered should not be disturbed. Instead, the historian/archivist at Lane Cove Municipal Library should be informed so that their historical importance can be determined and recorded. Small fragments can be taken in for inspection. Lane Cove bushland also has some special values found only in some bushland areas. Many of the rivers and waterways dissecting the eastern part of Sydney are lined with grey-green slopes of Sydney’s eucalypt bushland. Lane Cove is a waterside municipality with well over 50% of its boundary lying along the Lane Cove River. It is thus fortunate to share this distinctive scenery of blue waters and wooded slopes, sandstone outcrops crowned by twisted pink limbs of the Sydney Red Gum, mysterious stands of mangroves and lively long-legged waterbirds. This bush along the foreshores complements the water in many ways: aesthetically it is a backdrop to the waterways and it provides for water-oriented recreation especially picnicking and boating. It also provides nesting and night roosting sites for the mud-wading waterbirds and it preserves places along the shoreline where the Aborigines spent much of their time, gathering food. The Lane Cove Council logo uses just these aspects, the winding river, the green bushland slopes and the distinctive pink trunks of the Sydney Red Gum so common in our bush, to symbolise the special character of this municipality. Located so close to the centre of a large city, this area is fortunate in retaining bushland, both along the river foreshore and along its tributary creeks. This new logo (below) was adopted in 1988. Prior to this time the logo featured the old Figtree Bridge built over the Lane Cove River from Linley Point to Hunters Hill in 1885. At the time, this bridge, along with the old Gladesville Bridge and the Iron Cove Bridge, also built in the 1880’s, was the only link to the city centre by road for the whole North Shore. It was also the only bridge anywhere across the Lane Cove River linking the North Shore with Ryde and areas west of the river. Thus the Figtree Bridge was a very important transport link for Lane Cove Municipality when it was incorporated in 1895 and adopted a logo (at right). It was also a feature on the river well known to the many people who visited the recreation areas along the river by boat and ferry (see Chapter 10 for more details). 13 The Natural Environment of Lane Cove 4. VEGETATION COMMUNITIES OF LANE COVE 4.1 Naming Vegetation Communities Communities are named in several different ways: 1. The most commonly used terms are very broad descriptions of the vegetation type, such as ‘heath’ or ‘rainforest’. ‘Sclerophyll’ is frequently used in these broad descriptions. It refers to vegetation with ‘hard dry leaves’ such as eucalypts. 2. These general terms can be more specifically defined by referring to the dominant (ie. most common) plant species in the community. This is usually limited to two or three species. For example, a common association in Lane Cove is Smoothbarked Apple – Sydney Peppermint. 3. A community can also be named by its structural characteristics ie. height of the tallest plant layer and density of its leaf cover. This gives rise to terms such as ‘open woodland’, ‘low shrubland’ or ‘closed forest’. This classification, devised by Specht, is shown in the table below. Classification of Australian Vegetation by Structure (Sprecht, In Gibson and Anderson, 1981) Life form of tallest stratum Trees* >30 m Trees* 10–30 m Trees* <10 m Shrubs* >2 m Shrubs 0.25–2 m Sclerophyllous Non-sclerophyllous Shrubs <.25 m Sclerophyllous Non-sclerophyllous Hummock grasses Herbaceous layer Graminoids Sedges Herbs Ferns 100–70% (4)† Foliage projective cover of tallest stratum 70–50% (3 + ) 50–30% (3 – 1) 30–10% (2) <10% (1) (T)† Tall closed-forest (M) Closed-forest (L) Low closed-forest Tall forest Forest Low forest (Tall open-forest) ‡ Open-forest Low open-forest (Tall woodland) ‡ Woodland Low woodland — Open-woodland Low open-woodland (Z) Closed-heathland (C) — Heathland — Open-heathland Low-shrubland Shrubland Low-shrubland Open-shrubland Low open-shrubland (S) Closed-shrub (D) — Scrub Tall open-shrubland (W) — – – Hummock grasssland Open hummock grassland (G) Closed (tussock) grassland (Y) Closed-sedgeland (X) Closed-herbland (F) Closed-fernland (Tussock) grassland Sedgeland Herbland Fernland (Tussock) grassland Sedgeland Herbland Fernland Open (tussock) grassland Open-sedgeland Open-herbland — Very open (tussock) grassland Very open-sedgeland Very open-herbland — — — Tall shrubland Dwarf open-heathland Dwarf open-heathland (fell-field) (fell-field) Dwarf shrubland Dwarf open-shrubland (H) — — Open-scrub — * A tree is defined as a woody plant usually with a single stem; a shrub is a woody plant usually with many stems arising at or near the base. † Symbols and numbers given in parentheses may be used to describe the formation, e.g tall closed forest — T4, hummock grassland — H2. ‡ Senescent phases of Tall forest. Table from H. Recher, D. Lunney & I. Dunn, A Natural Legacy, Pergamon, 1986. All three ways of naming communities are commonly used in reference to vegetation, depending on the purpose of those referring to the community. For example, the Forestry Commission generally uses the dominant species as their interest is in the particular species of trees in an area. The description of the vegetation communities of Lane Cove in this chapter is based on the broad descriptive categories but also refers to dominant species in distinguishing various communities within the broad categories as well as some of their structural characteristics. The major community types originally present in Lane Cove were wetlands, dry sclerophyll forest (open woodland or forest), heath, and wet sclerophyll forest (tall forest). Within these broad types there were a 14 Vegetation Communities of Lane Cove number of variations of different major species as a result of slightly different conditions. Despite the depredation of settlement, there still remain examples of most of these communities in Lane Cove. Plants of these natural vegetation communities of Lane Cove demonstrate quite distinctive characteristics as a result of the particular environments and conditions in which they grow. 4.2 Factors Affecting Vegetation Communities A large and obvious component of the natural environment is its vegetation. Due to the wide variety of influences interacting to produce vegetation, it can vary enormously from place to place, not only in the actual plants, or species, present, but also in the ways the individual species are grouped together to form communities. Vegetation can even vary greatly within small areas as pockets of different conditions produce different groupings of plants responding to the varied conditions. For example, although Lane Cove is a relatively small area with the same general climate, it has a varied topography and variation in soils, both of which act to create different conditions and different communities. Although we have lost considerable portions of some of our vegetation communities to settlement, others still exist in bushland reserves and other patches of bush. Walking through these reserves, we can frequently observe the way the vegetation changes as local conditions which affect it change. Often conditions change gradually and the vegetation communities grade from one type into another without sharp, definable boundaries. Where they grade into one another, species typical of both communities are present, for example as conditions gradually get moister, drier, cooler or hotter. Sometimes, however, there is a sharp break or boundary between communities. A most obvious example of this in mountain areas is ‘the treeline’ , or the break between the forests of the slopes below and the alpine grasses above, which occurs where it becomes too cold for the trees to survive. In some mountain valleys it can act in reverse with the trees above and grasses on the floor of the valley where the cold air settles in a ‘lake’ and it is colder than the slopes above. Other sharp changes in conditions occur with a sharp change in rock type and accompanying soils and at the edges of estuaries, rivers or lakes. In the latter there is often not just one change in conditions (particularly in the amount of moisture and/or salt) but several over a short distance from the water, creating zones of vegetation with each change. This zonation pattern, as illustrated below, can be seen in many places around Sydney, including the Lane Cove River just north of Blackman Park (although the seagrasses would not be present). 15 The Natural Environment of Lane Cove In the rest of the bushland areas of Lane Cove the natural vegetation has distinct patterns which result from the particular combination of soils, topography and aspect. The protected and moist gullies with pockets of accumulated deep, fertile soils carry a wet sclerophyll forest of tall eucalypts with an understorey of rainforest plants. Moving up onto the sandstone slopes the soils become thin, sandy and dry and the vegetation changes to open dry sclerophyll forest with a shrubby flowering understorey. Where the top of the ridge is also sandstone and exposed and dry, the forest becomes drier and more open towards the top until it changes to a heath in the most exposed areas. By contrast, where the sandstone of the slopes gives way to a clay capping on the ridge, the forest becomes taller, moister and more closed as it becomes the wet sclerophyll forest with mainly grassy understorey of the ridge. 16 4.3 Wetlands and Swamps Vegetation Communities of Lane Cove Conditions In Lane Cove, wetlands occur in distinctive zones bordering the river where there is very moist soil, usually with periodic inundation by the tides or creek flows (see diagram on previous page). The nature of the communities and their particular species varies with the height and distance from the water (which determines moisture levels in the soil) and the amount of freshwater input from creeks (determining the salinity of the soil). Associated with bodies of freshwater are a different type of wetland with different species to those which tolerate the salt water along the river. There are also small swamps in patches of poor drainage in bushland areas. Communities and Species Mangroves occur in the zone closest to the water with the taller Grey Mangrove, Avicennia marina, next to the water and the shorter River Mangrove, Aegiceras corniculatum, on the inland side where there is better aeration in the soil (it does not have the pneumatophores of the Grey Mangrove). Both mangroves have thick, tough leaves with mechanisms to excrete the salt they take in with their water. They both also bear seeds which have swollen and begun to grow before they are shed, a mechanism to allow quick establishment in the soft mud. Salt marsh areas behind the mangroves have very high salt concentrations as evaporation of the high tide water leaves the salt behind. Thus these areas support only the various grasses and sedges which have adaptations to high salt levels. Casuarinas Inland and a little upslope from the saltmarsh, where it is less salty, is the zone of Swamp Oak, Casuarina glauca, sometimes with Paperbarks. Freshwater wetlands occur in Lane Cove mainly where artificial dams have created small bodies of fresh water. These carry water plants such as Pondweed and Duckweed, as well as swamp species such as Bullrushes, Typha australis, around the edge. Swamps may occur in areas with poor drainage and plants in such areas must adapt to waterlogging ie. lack of aeration in the soil, and often to quite acid conditions in the soil. Fruit or ‘nut’ of Casuatina littoralis Juncus ptismatocarpus Remnants Mangroves are found along much of the shoreline, especially upstream of Figtree Bridge. Excellent examples of the full range of communities in a zonation pattern are found along the River Walk to the North of Blackman Park and in Tambourine Bay on the east side of the creek. A small freshwater wetland is found on the lake formed by the dam on Stringy Bark Creek There are some patches of swamp related to poor drainage in Warraroon Reserve above the stone bridge. 17 The Natural Environment of Lane Cove 4.4 Wet Sclerophyll Forest Conditions These are eucalypt forests in moister conditions and generally with reasonably deep, fertile soils, either on the ridges with clay soils or in the more protected gullies where there is a build-up of alluvium. These differences in location produce two different communities. There is often confusion between ‘rainforest’ and the vegetation of the moist gullies. In Lane Cove the communities in the moist gullies are ‘sclerophyll’ because their major trees are eucalypts. The understorey in these areas often contains species which have rainforest characteristics but this does not mean the area is a rainforest. Communities The association of the clay ridges was Blue Gum with Blackbutt where it is drier, and also with Turpentine. In the moist gullies the community is dominated by Turpentine, Blackbutt and Red Mahogany with ‘rainforest’ understorey species including Coachwood, Lillypilly, Cheese Tree and Pittosporum. Plant Characteristics Wet Sclerophyll Forest Plants Wet sclerophyll, or tall open, forest is found in conditions between those of rainforest and those of the dry scIerophyIl forest. Thus the plant characteristics lie between the two extremes. The dominant trees are 18 Vegetation Communities of Lane Cove eucalypts with their leathery leaves but many of the rainforest understorey plants with the bigger, softer and greener leaves are found below. However, the trees are taller and straighter with denser canopies than in the dry sclerophyll as there is plenty of moisture and the soils are fertile. Tall straight trunks result from denser growth of plants and less light. This is found at its greatest extreme in a rainforest where the competition for light forces trees to grow very tall and straight with few side branches and a small but dense canopy head. At the other extreme, the openness of vegetation in a woodland, such as the dry sclerophyll, allows trees to twist in various directions and develop numerous side branches.

Rainforest plants live in a sheltered environment, in valleys under the taller trees, where there is shelter, warm temperatures and plenty of moisture. They do not have to conserve moisture: frequently they have to be able to shed it quickly so that it doesn’t weigh the plant down. Thus these plants tend to have broad, glossy deep green leaves which are often soft to touch. They may have a downward sloping point at the tip, a ‘drip tip’ for shedding water and a leaf shape which channels the water to this tip. These plants also often have quite dense canopies (foliage cover) as there is plenty of moisture for a lot of leaves. This canopy increases the shade below so that there is often little growing on the ground below these plants, apart from ferns. Most plants flower most brightly in the sun. As the rainforest plants live in shady environments, their flowers tend to be small and white to cream colours. However, they do then bear berries or fruits which may be luscious, fleshy and varied in colour. The berries shine amongst the deep foliage to attract birds to eat the berries and disperse the seed.

Fires will burn the edges of these wet areas but rarely extend far into their moist environment. Thus these plants have not developed adaptations to survive fire. Remnants There is a small vestige of the clay ridge Blue Gum and Blackbutt association in the upper part of Stringy Bark Creek in, and just downstream of, Stringy Bark Reserve, as well as in the very upper part of Bushland Park near Ronald Avenue. The moist gully association can be seen in the middle section of Bushland Park. 4.5 Dry Sclerophyll Forest: Conditions Dry sclerophyll forest is open eucalypt forest on the dry, infertile sandstone soils of the valley slopes. Thus it has many plants with adaptations to dry conditions. Plant Characteristics ‘Sclerophyll’ means having hard, leathery leaves, such as eucalypts have. Dry sclerophyll forest plants exhibit characteristics which contrast directly with rainforest plants in almost every way as they live in an environment where water is scarce and must be conserved. Thus the leaves are not only hard and leathery but may be small or narrow to reduce water loss from transpiration. They may also have a waxy coating for the same reason. Leaf colour is a dull drab olive green giving the typical look of the Australian bush. In the natural forest trees are not tall and their canopy, or foliage cover, is often quite open as their sandstone soils lack both the water and fertility for growing dense leaf cover or tall trees. Thus they let plenty of light and sun through to lower levels allowing the growth of many understorey plants. Sydney sandstone vegetation is quite remarkable for the variety (diversity) of plants which have developed in such an inhospitable environment. The understorey plants carry a wonderful variety of bright flowers, also an indication of the openness of their environment where the sun can reach them. These forests were frequently burnt and the plants have developed a variety of mechanisms to survive fire while some have come to depend on the fire occurring to reproduce or grow successfully. Plants such as eucalypts have normally dormant (epicormic) buds below the surface of their bark. Those parts of the trunk and branches which are not damaged by a fire can sprout new growth from these buds. They may also use this mechanism after other forms of damage such as a severe storm or insect/fungal attack. Many of the trees have either a thick bark or a white reflective bark to protect against the heat of fire or their climatic situation. There are many shrubs in these dry sclerophyll areas which are killed above the ground by a fire but their roots survive. These shrubs then resprout at ground level from the lignotubers. Yet other plants need a fire to effectively spread their seeds or open the hard casing to let the seed germinate. Banksia plants are killed by a fire but the seed pods on their cones only open properly with the strong heat of a fire to release plenty of seeds for new plants. As the new plants do not grow under the shade of a parent plant, it fits neatly that the fire kills the parent plant. Acacias (wattles) produce seed with a very hard seed coat for protection while it remains in the soil for years till the right conditions come for it to germinate and grow. A fire is required to crack open this hard seed coat and the fire also provides the ‘right’ conditions of open ground with plenty of sun and an ash bed with nutrients for plant growth. Many other small flowering plants also require these conditions to germinate and grow. Communities The lower slopes which have more moisture, more shade and more soil washed down from above support a community dominated by Smoothbarked Apple (or Sydney Red Gum) and Sydney Peppermint, sometimes 20 Vegetation Communities of Lane Cove Acacia floribunda Acacia longifolia Acacia parramauensis Allocasuarina littoralis Allocasuarina torulosa Angophora bakeri Angophora costata Angophora floribunda Banksia ericifolia Banksia integrifolia.

The upper slopes communities which tend to be hotter and drier with least soil accumulation, sometimes called transition to heath, are dominated by Scribbly Gum, Narrowleaved Apple and Red Bloodwood. Remnants The lower slopes community is our major remnant plant community in Lane Cove as these were in the gullies left undeveloped due to their slope. This community can be found in most of the reserves. There is less of the upper slopes community but there are some patches north of Epping Road, east of Pindaroo Place. Hakea dactyloides Hakea sericea 4.6 Heath Conditions Heath is found in the harshest environmental conditions ie. where it is most exposed and driest with the shallowest, least fertile soils. Thus heath faces environmental conditions even more extreme than the dry sclerophyll forest. It is found on the lower exposed sandstone ridge tops where the soils are extremely thin 21 The Natural Environment of Lane Cove and very poor, often only in pockets on shelves of sandstone. The plants have developed a number of characteristics to survive these very harsh conditions of exposure to heat and drying winds, lack of soils and nutrients and lack of moisture in the soil. Plant Characteristics With the lack of moisture and nutrients, heath has very few trees. It consists mainly of a dense shrub layer up to two metres high. The dense compact growth of the shrubs reduces exposure of the ground and individual plants to wind and sun and creates a cooler, more humid microclimate. The leaves have varied mechanisms to also reduce water loss through transpiration. Many heath plants have very small leaves or needle-like leaves and some rely on very hard leathery leaves. Others have fine hairs on the underside of the leaf to create a layer of still air around the stomata (the “holes” through which the plant loses its water in transpiration). To find water and survive in shallow soils many have a wide spreading shallow root system and others store moisture in an underground stem, or lignotuber. The lignotuber also provides for regrowth after a fire has destroyed the plant. As a dry area community, heath has always experienced fire and its plants have various adaptations to survive occasional fires. Fire can even be important to clear away dense but old growth and allow new plants to germinate and grow. However, very frequent fire can expose these areas to erosion and loss of the few soils and nutrients they have. Heath tends to grow in one relatively even height layer. With such exposure to the sun, the plants have also developed a wide array of bright flowers. SOME COMMON LANE COVE NATIVE EXAMPLES Banksia ericifolia Banksia marginata Kunzea ambigua Heath-leaved Banksia Silver Banksia Kunzea Banksia ericifolia Communities Our remaining heath is a tall heath type (to 2m) with small trees and shrubs including Banksias, Tea Trees and Kunzea. Remnants Heath is usually found on the most exposed parts of the upper slopes and ends of the ridges on sandstone, although pockets can be found on sandstone shelves in dry sclerophyll forest. There is very little remaining in Lane Cove as the ridges and upper slopes are mainly developed, but some can be seen on Manns Point, Greenwich around the grassy picnic reserve and lookout, and there are small pockets amongst the upper slopes dry sclerophyll forest. 4.7 Missing Communities The major missing communities are heath and the Blue Gum High Forest of the ridges now covered by development. This forest consisted dominantly of Blue Gum and Blackbutt in differing proportions according to aspect and other factors. The ground below these tall forests appears to have been mainly grasses and ferns. The major existing remnants of this type of vegetation, once covering the ridges of the North Shore, 22 Vegetation Communities of Lane Cove are the Dalrymple-Hay State Forest at St Ives, the Cumberland State Forest at West Pennant Hills and the Ludovic Blackwood Sanctuary at Beecroft. Also largely missing from Lane Cove is another clay soil community – that of Red Stringybark, Grey Gum, and Turpentine, There is a remnant of this community in Twin Road Forest in East Ryde. Stands of Forest Oak were also once found on the clay ridges of the upper North Shore but Lane Cove does not have any of this community now, if it did originally. Most of the trees of the clay ridges were valuable timber species and the major economic activity on the North Shore for at least the first forty years of settlement was timber cutting in its forests. For example, much of our Turpentine became the piles for Sydney’s wharves as it was found to be resistant to marine borer and the Forest Oak provided the shingles for the roofs of many settlers houses. Timber-cutting then gradually gave way to farming and the grand forests disappeared. However, although the communities have gone, there are still existing individual trees of the species which comprised these communities, including a number in the grounds of schools located on the ridges. 4.8 Changing Communities In the areas of remaining native vegetation in Lane Cove there are many areas where the communities have changed since settlement brought changes to some of the conditions which affect them. There have been two major changes: 1. The change of areas from true dry sclerophyll with typical dry sclerophyll understorey plants (many of the lovely flowering plants of the Sydney sandstone flora) to areas which have the dry sclerophyll trees, such as Smooth-barked Apple, with wet sclerophyll understorey of ‘rainforest’ species. Dry sclerophyll forest seems to be acquiring wet sclerophyll understorey for two reasons: * In many locations stormwater from developed areas flows directly into dry sclerophyll bush slopes from pipes, off roads etc bringing much greater amounts of moisture than were present previously. * The bush now rarely experiences fire. This enables some species, such as Pittosporum, which are normally killed by fire and used to grow in the wetter areas which were not burnt, to expand into the drier areas. These ‘rainforest’ type species have a much denser canopy than the dry sclerophyll species and they then shade out the usual species of these areas. With the increased shade, conditions become moister encouraging still more ‘wet’ species to grow. Thus many dry sclerophyll understorey species, including both flowering shrubs and herbs, are becoming rarer in Lane Cove, as well as disappearing entirely from some reserves. 2. Along the river foreshore communities have changed as sedge marsh and reed beds have given way to mangroves. This has occurred as settlement has provided very favourable conditions for the growth of mangroves. Settlement has put into the river great quantities of silt, eroded from roads and cleared land, and nutrients. Thus mangroves have grown on new mudflats along the river’s edge as well as taking over former saltmarsh areas. This happened in the mouth of Stoney Creek (now Blackman Park) which, in the 1880s was still the wide, open mouth of a creek with a few clumps of reeds and mangroves. By the time it was designated as a rubbish tip in the 1950’s the whole area was filled with mangroves. Change from saltmarsh to mangroves has occurred extensively opposite on the Ryde shore in Buffalo Creek and Kittys Creek. Most of the rest Acacia longifolia, of our foreshores where silt has Sydney Golden Wattle, accumulated, have acquired far named for its long, narrow leaves, more extensive stands or fringes or foliage of mangroves than they carried in 1788. 23 The Natural Environment of Lane Cove NATIVE MAMMALS KNOWN TO OCCUR IN KU-RING-GAI CHASE BANTRY BAY AND THE LANE COVE VALLEY, 1978 Scientific Name MARSUPALIA Dasyuridae Antechinus stuenii Paramedilae Parameles nasuta Isoodon obesulus Phalangeridae Trichosaurus vutpecula Burramyidea Cercartetus nanus Aerobates pygmaeus Petauridae Petaurus breviceps Pseudocheirus peregrinus Macropodidae Wallabia bicolor Macropus rufogriseus Phascolarchidaae Phascolaretos cinereus RODENTIA Muridae Rattus fuscipes Rattus lutreolus Hydromys chrysogaster Pseydomys novaehollandiae MONOTREMATA Tachyglossidae Tachyglossus aculeatus Ornithorhynchidae Ornithorhynchus anatinus TOTAL CONFIRMED SPECIES Ku-ring-gai Chase Bantry Bay Lane Cove Valley Stuart's marsupial mouse + + + Long-nosed bandicoot Short-nosed bandicoot + + + + Brush-tailed possum + + + Pygmy possum Feather-tail glider + + Sugar Glider Ringtailed possum + + + + + Swamp wallaby Red-necked wallaby + + (i) Koala + Southern bush rat Eastern swamp rat Eastern water rat New Holland mouse + + (ii) + + + Spiny anteater (Echidna) + + + Platypus + (iii) 7 6 Common Name 17 + (data from all available sources) (Order as In Kirsch and Calaby, 1977, based on Ride, 1970) Notes (i) may be escapees (ii) first record for Ku-ring-gai: Sept., 1977, A.B.

The Animals of Lane Cove 5. THE ANIMALS OF LANE COVE 5.1 Wildlife in the City Animals are the least frequently seen part of the natural environment and, for this reason, often the most exciting when we do see them. Many people, especially children, enjoy finding and observing animals of all sizes from the industrious ant to a speeding kangaroo or a cuddly koala. We tend to believe that cities have no wildlife left apart from insects and birds. Yet the recent NSW Urban Wildlife Survey found considerably more than this in many urban areas, if we just stop to observe it. The most obvious component of the wildlife is the birds, dealt with in a separate chapter, but there are other animals which have survived development. Some prefer their native bushland habitats, highlighting the importance of our bushland remnants. A few have adapted to suburbia so well that they are more common there than in their natural habitat. No study has yet been done to determine the currently existing species and population numbers of mammals, reptiles and amphibians specifically in Lane Cove. Such studies are difficult to undertake as, unlike plants, animals do not stay in one place. In addition, many of our animals, particularly the mammals, are hard to find because they are nocturnal and most of the survivors are those which are small or have been best able to hide from their many predators. The information in this chapter represents the best estimate based on available information in the absence of such a study. The poor known or assumed status of most of the animals listed in this chapter and in Appendices 6.1 – 6.3 illustrates the enormous impact of the loss of habitat to settlement and predation by introduced animals. These lists do not include those animals which became extinct in the area some years ago. For further information on the Urban Wildlife Survey and other general remarks on wildlife in the suburbs, see Urban Wildlife of NSW. 5.2 The Mammals of Lane Cove Of all our wildlife, mammals have been the most severely affected by the spread of settlement. In areas such as Lane Cove where the remaining bushland is long and narrow, most larger mammals cannot survive as there is both insufficient area to support them and too much pressure from surrounding suburbs and their people. Yet those which have survived, mainly tree dwellers or smaller bush dwellers, are quite common well supported by the remnant bush and gardens of our suburbs. As clearing and settlement, first for farms then for suburbs, began in this area over 170 years ago, Lane Cove long ago lost the large familiar mammals such as kangaroos, wallabies and koalas. The platypus could not survive when streams became muddy and polluted by stormwater outfalls and detergents which destroy the waterproofing of their fur. Ground dwelling native cats and bandicoots also gradually disappeared as bushland areas constricted. Today bushland of the Lane Cove Valley has far fewer species of mammals than Ku-ring-gai Chase (an area with a very similar natural environment), even in the larger areas of bushland in the upper part of the Valley (see table opposite). In Lane Cove Municipality there would be few bandicoots and echidnas left. However, our mixture of bushland pockets and plentifully treed gardens suits possums and bats very well and they are frequently seen and heard in the evenings. The major native survivors in all animal groups are those which are small and well camouflaged so that they can hide from predators, or are protected from predators by spikey armour (echidna) or by living in trees (possums, bats and sugar gliders). The major enemies of the native animals are introduced and feral animals, particularly foxes and cats. To find most native animals requires keen observation of the signs of their presence. Our native mammals are mainly nocturnal but the various signs of animal presence can often be 25 The Natural Environment of Lane Cove seen on walks eg. nests, droppings, sounds. In the evening possums and bats can often be seen around the house and garden and animals may occasionally be spotted in the bush if observers are very quiet. All three major groups of Australian mammals, monotremes, marsupials and placental mammals are represented in Lane Cove. Animals known to be, or possibly, still present in Lane Cove are listed in each grouping with an indication of their status as known. Monotremes Echidna (Spiny anteater) Tachyglossus aculaetus Unlikely Antechinus stuartii Unlikely Echidnas are ant and termite eaters. They are mainly diurnal but often also active at night. At any danger they roll into a ball, presenting only their spiky armour. They have distinctive cylindrical droppings which are large and full of ant shells – a good sign to look for as indicating their presence. Marsupials Stuart’s Marsupial Mouse (Brown Antechinus) Long-nosed Bandicoot Sugar Glider Feathertail Glider Ring-tailed Possum Brush-tailed Possum Eastern Pygmy Possum Perameles nasuta Petaurus breviceps Acrobates pygmaeus Pseudocheirus peregrinus Trichosurus vulpecula Cercartetus nanus Unlikely Predicted Unlikely Common Common Unlikely Feathertail Glider Marsupial mice are mouse size but very different. They have slender tails and short broad feet. They also have a mouth full of sharp teeth (house mice have chisel-like gnawing teeth) as they are carnivores eating insects and lizards. They are nocturnal and live on the ground, often in hollow logs or under debris. Bandicoots live on the ground digging small conical holes with their forelimbs. They then explore the hole with their pointed snout to eat earthworms and insects. They are nocturnal and live in a well-hidden nest during the day but the holes they dig in search of food can be found. They have not been sighted for many years in Lane Cove and may not be present any more. The Brush-tail Possum is the most common local possum and they are active at night in trees (and house ceilings). They are vegetarian, eating fruits, buds, bark and eucalypt leaves. They are territorial and solitary, often having noisy disputes over territory. Ring-tail Possums also live in trees and are active at night, using their ‘prehensile’ tails to grip braches almost like a 5th leg. They sometimes make nests, called dreys, which can be seen in the bushland in the dense but fine leafed foliage of trees such as Banksia ericifolia and Kunzea ambigua. Although they are territorial, they are much more sociable than brushtails and sometimes share nests. Their diet is similar to the Brush-tail. Unlike the Brush-tail, they rarely nest in houses. If possums are heard thumping across the roof at night, they can be located by quietly searching the area they were last heard in with a torch. Their eyes glow brightly in the torchlight when located. Gliders are possums with a membrane of fur-covered skin stretched from the hand to the feet to enable them to glide from tree to tree. They are both small and hard to find with the Feather-tail particularly small and secretive. The Sugar Glider is nocturnal and eats gum (sugars) exuded from eucalypts and acacias (wattles) as well as flowers, fruits and insects. They are social animals and often live in groups of up to seven or eight. 26 Brushtails are larger than Ringtails with a thick, dark bushy tail. The Ringtail has a tapering tail, the end third of which is white. BATS AND GLIDERS The Animals of Lane Cove There are three groups of possums and some species in each group are gliding possums. There are two groups of bats: large fruit-eating bats and small insect eating bats. All bats fly. There are some important ways bats and gliding possums are the same and important ways they are different. SIMILARITIES 1. They are mammals: warm-blooded, furry, giving birth to baby young which suck their mother's milk. 2. They feed at night. 3. Most have only one young each year. 4. All species are protected in NSW. 5. Their survival is threatened from loss of habitat due to clearing of trees and forests. 6. They do not harm people or spread disease. BATS DIFFERENCES 1. Bats are placental mammals. 2. Bats are the only mammal which can truly fly and whose major means of movement is flight. 3. Wing is a thin membrane from shoulder to tips of specially elongated forearms and forearms and fingers which are enclosed in the wing and make it move. 4. Wings are flapped in flight and long distances can be covered. GLIDERS Gliders are marsupial mammals. They only glide short distances between trees. They have a skin flap stretched between the outer edge of the hand and the ankle. The flap is held outstretched as they first leap, then glide. Sugar Glider Grey-headed Flying Fox 27 The Natural Environment of Lane Cove Placental Mammals Fruit Bats or Megabats Grey-headed Flying Fox Little Red Flying Fox Pteropus poliocephalus Pteropus scapulatus Common Predicted Microbats Gould’s Long-eared Bat Lesser Long-eared Bat Gould’s Wattled Bat White-striped Mastiff Bat Nyctophilus gouldii Nyctophilus geoffroyi Chalinolobus gouldii Tadarida australis Occasional Common Common Occasional Bats are the only mammals which can fly, unlike the possums which only glide short distances between trees (see the table on the previous page for other similarities and differences). Megabats, also known as Fruit Bats (after their eating habits) or Flying Foxes (after their appearance) are larger bats with large eyes and a long ‘dog-like’ snout. They do not echo-locate (use a type of sound radar for navigation) but have very good vision with their large eyes. They live in large colonies (eg. at Gordon) and at night disperse to feed on fruits and blossoms. They have a bad reputation with orchardists for decimating valuable fruit crops. However, their preferred food is eucalypt blossom and native fruits and berries, especially from rainforest species. They only raid orchards when natural food sources are scarce. Microbats are also nocturnal but they are small, with small eyes and they use ultrasonic pulses for navigation (echolocation) and to catch insects, their major food source. There may also be native rats in Lane Cove but they have not been found in any recent survey. 5.3 The Reptiles of Lane Cove Reptiles are a fascinating group of animals, variously ignored, maligned or feared. Yet they are a common component of urban wildlife, more frequently and easily seen than the mammals. Many reptiles, which include lizards, snakes and turtles, have a number of interesting body adaptations which allow them to live in a variety of harsh and difficult environments. Such adaptations include a skin which seems dry and leathery but is actually a series of tiny interlocking scales which both protects them against predators and conserves water. This skin is relatively inflexible so that it is shed each year to allow for growth, or more frequently by young animals. The following describes the various groups of reptiles and lists those found in Lane Cove. Lizards Lizards are the largest group of reptiles. They are distinguished by having: * legs * a fleshy whole tongue (although it is forked in goannas) * a tail as long, or longer, than the body * an external ear opening * food mainly insects with some leaves and flowers; large lizards also eat small snakes, frogs and nestling birds (which they tear and grind, unlike snakes which swallow whole) There are five different families of lizards: goannas, skinks, geckoes, dragons and legless lizards. GOANNAS Lace Monitor Sand Goanna 28 Varanus varius Varanus gouldii Unlikely Unlikely The Animals of Lane Cove Goannas, or monitor lizards, are diurnal and some of the group, up to 2 metres long, are the largest lizards in Australia. The 30 species of monitor lizards in Australia represents three-quarters of the world’s total. They have well developed limbs and claws with a long neck and tail and coarse skin. The long neck enables them to draw back a long way before making a quick dart at their prey.

They are generally fairly smooth-scaled, often appearing shiny. Most are active during the day and have short, well developed legs and a short, round body. Small skinks are very agile and dart into cover when alarmed. Larger skinks rely more on threatening poses, such as baring a brightly coloured mouth, enlarging the neck area or making hissing noises. GECKOES Wood Gecko Leseur’s Velvet Gecko Southern Leaf-tailed Gecko Thick-tailed Gecko Diplodactylus vittalus Oedural eseurii Phyllurus plalurus Underwoodisaurus milii Unlikely Rare Occasional Predicted Leaf-tailed Gecko Geckoes are small lizards, usually nocturnal, sheltering beneath logs and stones or under loose bark on trees during the day. Their feet may be clawed or have circular pads enabling them to climb smooth surfaces and cling to the underside of tree limbs, rocks etc. The tail of some species looks like the head. The tail can be discarded if the gecko is attacked, and a new one grown. DRAGONS Jacky Lizard Bearded Dragon Eastern Water Dragon Amphibolurus muricatus Predicted Amphibolurus barbatus Unlikely Physignathus leseurii Occasional LEGLESS LIZARDS Burton’s Legless Lizard Common Scaly-Foot Lialis burtonis Pygopus lepidopus Dragons generally have a rough scaly skin and crests or frills around the neck and head which are often used, together with a brightly coloured mouth, in a threatening display. They are active during the day and generally on the ground but many are capable of climbing and swimming. Rare Unlikely This is a small group of lizards unique to Australia with no forelimbs and the hindIimbs reduced to a flap. They look very like snakes but can be distinguished from them by a number of features including a broad fleshy tongue (snake tongues are forked) and uniform scales round the body (snakes have broad scales on the belly). 29 The Natural Environment of Lane Cove Snakes The outstanding difference between lizards and snakes is in the structure of the lower jaw which allows an amazing amount of distension for the snake to swallow animals larger than its own head whole. With no limbs the rest of the body has no bony structure to constrict the passage of large meals down the body. Other distinctive features of snakes are: * A thin forked tongue which darts in and out to take particles from the air to test – its sense of smell. * Small finely pointed teeth to grip their prey (not for cutting or chewing). * Smooth sinuous movement with the entire body following the same path, enabling it to creep up on its prey without disturbing it. The movement occurs through a series of waves of muscles which lift small sections of the body and push it along. * A tendency to hibernate in winter. Most snakes are not venomous to adult humans. Even if they are venomous they prefer to escape rather than attack. They will bite if injured or startled, cornered or taunted. If snakes are encountered they are best just observed and allowed to move or escape as they wish. There are four major groups of snakes: BLIND SNAKES Blind Snake Rhamphotyphlops nigrescensRare (formerly Typhelina nigrescens) Blind Snakes live mainly below ground and under rocks and are very similar to earthworms in appearance. They eat termites and ants and their eggs. PYTHONS Diamond Python Morelia spilotes ssp. spilotes Predicted Pythons are non-venomous but with powerful bodies which twist around their prey to choke it. Their tail is prehensile (used for gripping). There are only a small number of python species in Australia, mostly in northern Australia but they include Australia’s largest snakes (up to 6 metres long). COLUBRID SNAKES Common Tree Snake Dendralaphis punctulatus Predicted These are harmless snakes which have either no fangs or rear fangs so positioned it is difficult to inflict a bite on humans. They also have a prehensile tail. Although common in other parts of the world, there are only a few species in Australia. ELAPID SNAKES *Common Death Adder Golden-Crowned Snake Yellow-Faced Whip Snake Red-Naped Snake *Black-Bellied Swamp Snake *Eastern Tiger Snake *Red-Bellied Black Snake Acanthopis antarticus Cacophis squamulosus Demansia psammophis Furina diadema Hemiaspis signata Notechis scutatus Pseudechis porphryiachus Predicted Unlikely Predicted Unlikely Unlikely Predicted Occasional Red-bellied Black Snake Elapid snakes have front fangs which are well positioned for injecting venom. They are the largest group of snakes in Australia. Although most are not dangerous, some of them are amongst the world’s deadliest snakes. Those which are dangerous amongst the Lane Cove snakes above are marked with a *. 30 The Animals of Lane Cove Turtles Turtles are predominantly aquatic. In Australia they fall into two main groups: the long necks and the short necks. Both appear similar with a retractable neck and webbed, clawed feet which can all be withdrawn into the shell in times of danger. They spend most of their time in the water but may be found crossing dry country to get from one swamp to another. There is only one species of turtle in Lane Cove: Long-Necked Tortoise Chelodina longicollis 5.4. The Amphibians of Lane Cove Rare There are approximately 200 species of frogs in Australia, of which 9 are found in Lane Cove. All frogs have the same basic body shape but they vary in other ways, particularly in size and colour patterns. As colour for camouflage is an important protection, frog colour frequently relates to habitat. Many of the NSW tree frogs are green with pale white or yellow underbelly and the ground frogs are brown, black or putty colour. There are two major families of frogs which have different characteristics, discussed below. Both families are represented in Lane Cove. Leptodactylidae (Myobactrachidae) – Ground Dwellers The ground dwelling frogs have skins which are rougher and may have raised bumps. They do not have suction caps as they do not climb but live on, or below, the ground. Their colours are duller earth colours but many have distinctive striped or spotted patterns.

Yet the Lane Cove River bordering Lane Cove Municipality provides two different environments for aquatic life which affects the number and type of fish found there. Below Figtree Bridge the river is estuarine ie. its salinity is close to that of seawater and it includes the variety of marine microenvironments required to support a diversity of marine life, including a diversity of fish species. There is deep water, shallows with mudflats and sea grasses, rocky shores and mangrove flats. This section of the river thus supports a range of fish species and is important as a nursery area for juvenile fish such as flathead, Whiting, sand mullet, leatherjacket and silver biddy. Above the Figtree Bridge area is a more riverine environment as the freshwater component of the water increases. Species in this section must be euryhaline (able to tolerate both fresh and salt water) and diversity, 31 The Natural Environment of Lane Cove or the number of different species, drops as does abundance (the total number of fish). Here the most common species are the flat-tail mullet and the sea mullet. Prawns and various types of shellfish have also been common in the river in the past but are less common today. 5.6 Insects and Spiders Butterflies are the only part of the invertebrate world appreciated by most people. The rest are generally despised as a nuisance when they invade our homes and gardens or regarded with terror as the deadliness of the funnel-web and red-back spiders is transferred to all other spider species. Recent documentary and television programmes have shown us what an amazing world of invertebrates exists around us. Many have evolved complex behaviour patterns and relationships with plants or other animals. They play a very important role in the health of natural systems in many different ways from the pollination of plants to the breaking down of plant and animal remains. Insect populations out of control are an indication of imbalance in natural cycles, usually induced by the activities of people. Actual species found in Lane Cove are not detailed in this section but there are many varieties of butterflies, moths, beetles and spiders to be found, as well as grasshoppers, ladybirds, cicadas, flies, wasps, praying mantids, crickets, dragonflies and bugs (insects which suck). There are also termites, ants, cockroaches and various other insects on the ground and in the leaf litter. See references for works which provide detail to help identify many of these creatures which can be found anywhere there are earth and plants. 5.7 Introduced Animals Praying Mantis Introduced animals have become very prevalent in urban bushland reserves, in the same way as introduced plants (weeds or feral plants) have taken over the vegetation in many areas. At the same time as we have disturbed the native animals and reduced their habitat, we have also introduced a number of animals which can outcompcte the natives. However, the damage which feral animals are doing to our wildlife is less easy to see than the damaging effects of weeds. Native mammals are mainly nocturnal and all the animals are shy and tend to hide, even when they are present. How difficult it is to then assess how great the damage is to their numbers in any given area! The major impact of introduced herbivores is to compete with natives for food supply and habitat. Some species reproduce so prolifically that they can quickly outstrip native populations and place great demands on food resources. Carnivorous species, on the other hand, such as cats and faxes, prey directly on native wildlife and there is likely to be a direct correlation between the numbers of these animals present in a reserve and the damage done to wildlife. Even well-fed domestic cats hunt instinctively and will proudly bring home their latest ‘kill’, often a native bird or small animal. (Cat owners should always have Fox a bell on their cat’s collar and keep their cats inside at night when they do much of their hunting and native mammals are active).

THE BIRDS OF LANE COVE 6.1. Birds in the Environment Birds are an important part of the natural environment, playing a vital role in various parts of the functioning of ecosystems. Yet, people tend to value birds because they like them. They are pretty, or little and cute, or make delightful sounds, or behave in interesting ways we can observe. We like to watch flocks of birds wheeling and swooping across the sky, go and feed the ducks on the pond in the park with the children or stop and listen to the variety of their calls in some quiet bushland. They have inspired poets, artists and musicians, as well as producing in many people over the ages, the deep desire to fly. On the other hand, birds may not be appreciated when they eat a farmers’ fruit or grain crop or when cockatoos and parrots attack the timber on our deck. Yet, whether loved or hated, birds are so often seen in terms of what they do, or don’t do, for us, or to us. Due to their mobility, and the fact that they visit our gardens, they are not often considered as part of a functioning ecosystem in the bushland and the impact of our settlement on the birdlife is rarely realised. Birds both play their part in the operation of the ecosystem, and are dependant on it. Birds serve their function primarily through the food they eat, be it insects, nectar, seeds or berries. The insect eaters are extremely important in controlling the numbers of various insects. Without the birds to prey on them, populations of insects can explode and wreak terrible havoc on crops and native vegetation. Practices of the past which have ignored the role of birds have resulted in significant destruction of both. For example, it is thought that slaughter of the locust-eating Australian Bustard last century has significantly contributed to the continuous cycle of locust plagues we now experience. It is also thought that overclearing of bird habitat contributed to the defoliation of New England forests by Christmas Beetle and subsequent dieback of the forests. Other insect-eaters are the currawongs, which devour regular plagues of stick insects in the forests of Southeastern Australia, and silvereyes which eat large quantities of aphids. Insect control in your garden by birds can be a good reason for not keeping a cat, or at least putting a bell on it, so that the birds will visit. Like bees, honeyeaters perform a very important role in pollination of flowers by taking the pollen with them from flower to flower. Cross-pollination from a variety of species is important to the long-term health of vegetation, Many birds eat the seeds of plants while some birds prefer the berry fruit which many plants bear, especially the plants of wetter areas. The birds then distribute the undigested seeds in their travels and this ensures continued survival of the plant in many places. (In the case of birds eating the berries of weed plants, this mechanism of dispersal is unfavourable to the bush but should encourage us to remove the weed plants.) 6.2. The Impact of Settlement on Birds Despite their mobility birds, like other animals,live in, and are adapted to, particular habitats. We tend to associate birds with the tree tops but although many do live in this environment, others are ground dwellers, both nesting and feeding there. Some spend most of their time in the air or on the water while others wander on mudflats during the day and roost in nearby trees only at night. Many small birds like shrub habitat in which they have plenty of protection and cover – they have neither the wing power to be constantly flying up to the tree-tops, nor the desire to compete with the larger birds there. Thus birds occupy different niches in the environment and many species can live in the one area with different sources of food and different living spaces. Each species is dependant on its particular environment. Any change in birds’ surroundings means a change in both the species mix and the numbers in each. The disappearance or appearance of trees, bush, grass and shrubs determine whether birds survive, increase or withdraw. 33 The Natural Environment of Lane Cove FOOD NICHES Birds occupy, and gather their food from, different parts of the environment to more efficiently use resources and minimise competition between species. Birds of the air gather insects, birds in and around the tree canopy look for insects, seeds or nectar while others gather these in the shrub layer, birds on the ground search for insects or grass seeds, waders gather small aquatic animals on the mudflats and swimming birds dive for fish. Settlement by people clears away large areas of bush almost completely, thus removing the habitat for many birds until gardens and other vegetation are re-established. Settlement also has considerable impact on the bird habitat of the remaining bushland, particularly along its edges. These impacts may be: * Use of pesticides and herbicides on gardens, road verges, ovals etc where ground dwellers feed. * Clearing of shrubs to create a ‘park’ with mown grass under scattered larger trees. * Noise * Predation by cats * Changes in fire patterns making vegetation more, or less, dense, than individual birds prefer. * Invasion by weeds which reduces the native food sources and changes the density of vegetation growth, making the habitat unsuitable. The birds most likely to be eliminated by the destruction of large areas for settlement are the largest birds as they have the largest range (area over which they move in search of food) eg. eagles, and those whose habitat has disappeared altogether eg. in Lane Cove, those which lived only in the forests of the shale ridges. The birds most likely to be affected by the kinds of habitat changes listed above which occur in remaining bushland, are the smaller birds and the ground and shrub dwellers. Birds introduced by settlement also compete with native birds for food and habitat, sometimes taking over certain niches. Introduced birds also tend to thrive in the more disturbed areas such as built-up areas, gardens, weed patches etc. Common mynas, starlings and house sparrows now make up 75% of the bird population in some suburban areas, as illustrated on the next page. However, settlement can also benefit some native birds with greater availability of food and by providing more of certain types of habitat such as cleared and grassed areas, ponds and lakes. Currawongs appear to have dramaticaly increased their numbers due to the availablity of winter food berries of introduced plants such as lantana, privet, pyracantha and camphor laurel. However currawongs then prey on the nestlings of smaller birds. With increased currawong populations, this has probably meant large losses in the numbers of the smaller species over the last 20 years. 34 The Birds of Lane Cove BIRDS IN THE URBAN ENVIRONMENT common starling Sturnus vulgaris before development density of birds: 6/ha number of species: 13 woodland is cleared new suburb is built striated pardalote Pardalotus striatus red-rumped parrot Psephotus haematonotus Australian magpie Gymnorhina tibicen density of brids: 2/ha number of species: 7 suburb two years old gardens established growth to maturity established suburb 20 years old native species introduced species house sparrow house sparrow Passer domesticus pied currawong Stepera graculina density of birds: 6/ha number of species: 10 house sparrow The illustration above demonstrates the impacts that settlement has on bird populations, with a significant initial decrease in bird species and in total numbers of birds, but with a recovery over a period of time as gardens are planted, trees grow and the habitat diversifies. However, the variety of species in the study represented here (in Wagga Wagga, NSW) did not recover to pre-settlement levels and most of the increase in total numbers of birds was of the introduced house sparrow: * Study by D.N. Jones "Temporal changes in the suburban avifauna of an inland city", Aust Wildl. Res. 8: 109-19. Illustration from A Natural Legacy: Ecology in Australia, eds H. F. Recher, D. Lunney & I. Dunn, Pergamon, 1986. 35 The Natural Environment of Lane Cove 6.3. Birds in Lane Cove Australia has about 700 different species of birds including about 500 land birds, 100 swamp and sea birds (the rest are migratory birds and rare visitors). 158 species of birds have been identified in the Lane Cove Valley below De Burghs Bridge. Not all of these would be found in Lane Cove (especially the freshwater species living above the weir in the State Recreation Area). In addition, some of them have been sighted only very rarely. Many are migrant species which fly long distances to arrive for the spring and summer months whilst others visit the area occasionally. Appendix 7 is a comprehensive list of the birds of Lane Cove. It may not include every bird ever seen in Lane Cove but does include those likely to be seen, even if rarely, as well as a guide to the most common habitat for each bird. This listing is able to draw on detailed works available specifically on birds of Lane Cove. Far more is known of the species and status of our birds than of our animals particularly through the long-term records of several birdwatching clubs. A 1978 Macquarie University study by Sarah Stephens (see references) using available bird watching records, compared the effects of settlement on bird species and populations in areas with with different levels of development. This study found that, although actual species varied a little due to different habitats, there was little difference between the total number of species present in the Lane Cove Valley and in Ku-ring-gai Chase where there are larger areas of bush less affected by settlement. There was also little difference in the abundance of the various species with similar proportions of the total number of species found to be common, uncommon or rare in the two areas. The study also reported changes which had been observed in birds of the Lane Cove Valley over the previous 30 years. There had been major increases in 9 species (3 of which are introduced), major decreases in 19 species and extinction of 3 species. However, it is difficult to be accurate with bird studies. Often areas closest to settlement have records of more birds than areas further away simply because there are more bird watchers making observations. It does not necessarily reflect the true differences in birds of those areas. Lane Cove has a variety of different habitats for birds including gardens, woodland and forests, open grasslands, mangroves, estuarine mudflats and a freshwater darn. To understand the world of birds it is useful to consider them as part of various broad groupings based partly on their habitat or their characteristics and partly on what they” eat and the way they obtain their food. The birds listed here are all the Lane Cove birds in each group which are relatively common or likely to be seen in gardens, on bushwalks or around the shoreline. Introduced birds are indicated by *. Water Birds Aerial Birds: usually seen flying over water or resting around the shoreline, includes albatrosses, petrels, gulls, gannets, terns, shearwaters and frigate birds. Silver Gull Crested Tern Swimming Birds: usually seen swimming or perched near water. They all have short legs with at least some webbing between the toes. They include penguins, cormorants, shags, phalaropes, grebes, ducks, swans and geese. Australian Pelican Pied Cormorant Little Pied Cormorant Little Black Cormorant Black Duck Mallard Grey Teal Chestnut Teal 36 Little Pied Cormorant Pelican Wading Birds: usually seen on beaches, mudflats, islands and around swamps and lakes. They have long necks, legs and bills for wading in shallow water and poking around the mudflats for their food. They include egrets, herons, bitterns, storks, cranes, oystercatchers, stilts, curlews, godwits, plovers and snipe. The Birds of Lane Cove White-faced Heron White Egret White Ibis Royal Spoonbill Spurwing (Masked) Plover Reed Birds: usually secretive and hard to see but quite vocal and obviously heard in reed and swamp areas. They include crakes, rails, ganninules and the reed-warbler. Dusky Moorhen BIRD BODY DESIGN There are many different types of birds living in all different parts of the environment from high in the air to low on the ground or in the water. Thus they are able to use many different sources of food and spaces to live without competing with each other. Their bodies display many features which adapt them to best live in their particular habitat, or be able to efficiently obtain their food. The bills and the legs and feet of birds are parts of their bodies with these special design features. Short stubby but strong bill for collecting insects from leaves and under bark Strong hooked bill for tearing meat Webbed feet for swimming Strong legs and a flat foot for walking Long legs and bill for wading and finding food in mud or shallow water Bill with strong upper and lower sections for cracking seed Curved toes with one toe opposite to others for clutching onto branches Long curved bill for collecting honey out of flowers Large bill for catching fish Heads and feet drawings mainly from Brian Shadwick, Skills Through Science Vol. 2, Science Press, 1988. 37 The Natural Environment of Lane Cove Land Birds Ground Birds: a) birds which feed on the ground and never, or very seldom, perch on trees. These are mainly birds of the open plains so there are very few in Lane Cove – only the Painted Button-Quail which is not common. b) birds which feed and spend much time on the ground but also perch in bushes and trees. These include pittas, thrushes, scrub-birds, bristlebirds, wagtails, larks, pipits, whipbirds, wedgebills, babblers, quailthrush, grasswrens, scrubwrens, whitefaces, chats, starlings, mud-nest builders, magpies and lyrebirds.

THE ABORIGINES OF LANE COVE 7.1 The Local Tribes Aboriginal people were grouped according to their language and dialect. In the Sydney region there were three major language groups: Kuring-gai in the north, Dharawal in the south and Dharug in the west (the central area between the Harbour and Botany Bay, east of Parramatta, is disputed by academics ie. whether the aborigines here spoke a dialect of Dharug or Kuring-gai). The major groups, or tribes, were divided into sub-groups, or clans, sometimes speaking different dialects of the main language. The names of the clans were formed by adding “gal” to the name of the area where they lived. Kuring-gai was spoken at least in the area from the Lane Cove River to the coast, Port Jackson to Botany Bay. Near the harbour, in the areas of the present Lane Cove and North Sydney, were the sub-group Cammeraigal” who were renowned as powerful warriors. The following are excerpts from the writings of two of the officers on the First Fleet pertaining to the Cammeraigal: Those who live on the north shore of Port Jackson are called Cam-mer-raygal, that part of the harbour being distinguished by the name Cam-mer-ray. Of this last family, or tribe, the selllers had heard Ben-nil-long and other natives speak (long before they were other wise known) as of a very powerful people who could oblige them to all end wherever and whenever they directed. They were afterwards found to be the most numerous tribe yet discovered. It so happened they were also the most robust and muscular. To the tribe of Cam-mer-ray also belonged the exclusive and extraordinary privilege of exacting a tooth from the natives of other tribes inhabiting the sea-coast, or of all as were within their authority. The exercise of this privilege places these people in a particular point of view and there is no doubt of their decided superiority. (David Collins, Account of the English Colony in NSW, 1798) Whenever he (Bennilong) recounted his battles, “poized his lance, and showed how fields were won,” the most violent exclamations of rage and vengeance against his competitors in arms, those of the tribe called Cam-ee-ra-gal in particular, would burst from him. And he never failed at such times to solicit the governor to accompany him, with a body of soldiers, in order that he might exterminate this hated name. (Watkin Tench, A Complete Account of the Settlement of Port Jackson, 1793) The clan was both the basic landowning unit possessing sacred sites within a specified territory and the basic economic unit which hunted and gathered food for its members within that territory. It consisted of a few related families numbering up to 50 or 60 people. However, the whole group did not necessarily stay together all the time. Families would separate and go different ways to find food but the whole group could be quickly gathered in the case of a dispute with a neighbouring clan, where a local surfeit of food was found or for ceremonial purposes. 7.2 Aboriginal Survival in the Environment of Lane Cove Almost everything the Cammeraigal used, wore or ate had to be found in their territory of North Sydney/Lane Cove. They made their own tools, weapons, canoes, nets and carry baskets from the materials found in the bush. They ate only what they could find in the bush or the harbour and river and they slept under the sandstone rock overhangs which abound in the area, or, where there was no suitable overhang, in a simple lean-to made of branches covered with sheets of bark. Note that the Retirement Village next to Lane Cove Public School is NOT named after the local Aboriginal tribe. The Kamilaroi were located in northern inland NSW. 40 The Aborigines of Lane Cove The only item which the Aborigines of eastern Sydney seem to have obtained from outside their own territories in the time prior to European settlement was stone suitable for hatchets. This came from the Nepean River by trade or ceremonial gift exchange. Apart from hatchets, stone tools were rare in coastal areas at this time. Shell was used instead of stone for cutting and scraping. However, more plentiful stone tools have been found in archaeological sites in coastal areas dating from over one thousand years ago. This indicates that the local Aborigines adapted over a period of time to their environment, substituting the local resource for their more traditional, but locally hard to get, stone. All the groups living along the coast and estuaries depended on the sea as the basis of their livelihood. The Cammeraigal utilised those resources edging their territory: the harbour and the river. They called the river we know as Lane Cove, “Turrumburra”, which has been said to mean ‘the second waterway on the right facing the setting sun’, an obvious meaning sitting in a canoe on the harbour but has not been confirmed as correct. Both the men and the women fished from canoes – the men with spears and the women with hooks and lines. Turtles were caught and shellfish were an important part of the diet, gathered mainly by the women from the rocks edging the water and from the mud and sandflats in the river. They ate a variety of shellfish, notably rock and mud oysters, mussels, cockles, crabs and turbans. By the time the Europeans arrived, centuries of collecting shellfish, then gathering for a fire and a meal nearby, had resulted in large accumulations of the discarded shells in middens along the shoreline, sometimes out in the open and sometimes next to a rock shelter. There was so much of this shell that it was able to be collected by the new settlers and used for lime in mortar for building. Despite this collection, middens can still be found in bush areas along the water’s edge. However, in winter when fish and shellfish were scarce or in stormy weather when they were difficult to catch or collect, the Cammeraigal depended more on their land-based resources. These were found in three major environmental zones: * the wet sclerophyll forest and rainforest vegetation of the moist creek gullies rich in fruits such as figs, lillypilly, native grape and apple berries. * the dry sclerophyll forest and heath of the sandstone slopes and lower exposed ridges which provided sweet nectar from Banksia, Grevillea and waratah flowers, fruits such as brush cherry, native currant and geebungs and small animals such as bandicoots, bush rats, possums and native mice. * the tall forests of the shale ridges under which grew bracken fern and grasses. The bracken fern root was an important source of carbohydrate in the winter while the open grassy areas under the trees attracted larger mammals such as kangaroos and wallabies and made them easier to hunt. Birds from all zones, including waterbirds of the shoreline areas were also part of the Cammeraigal diet. The Aborigines major tool for manipulating their environment to enhance the food supply it provided, or to make hunting easier, was fire. Of the three major zones (above) those burnt would have been the sandstone slopes and the grasses under the tall forests. The moist gullies along the creeks are too wet to burn and many of the plants which grow there are sensitive to fire ie. they are killed by a fire and do not have the regenerative techniques of plants in the drier zones. The sandstone areas were burnt to trap animals and possibly to get better crops of the fruits from new growth. The Cammeraigal were described by Governor Phillip as frequently burning in dry weather to catch rats and other animals. Another First Fleet officer, Captain Hunter, commented that; “...two thirds of the trees in the woods were very much scorched with fire”. Most of the sandstone areas would have been burnt on an irregular basis with anyone area experiencing fire as frequently as five to seven years apart and others as much as fifteen years apart. Thus at anyone time the bushland was an irregular mosaic of burnt and unburnt areas providing for a variety of stages of growth of plant systems and habitat for animals, some of whom prefer open areas and others prefer plenty of shelter in the dense growth of areas unburnt for some time. On the ridges, the grasses under the tall forests were probably burnt to keep them free of shrubs. 41 The Natural Environment of Lane Cove The local tribes used the ridges for travel (as we do) and probably preferred them clear of shrubs which made travel difficult. Shrub invasion would also eliminate the bracken fern they depended on in winter. Captain Hunter commented: We have also had much reason to believe, that those fires were intended to clear that part of the country through which they have frequent occasion to travel, of the brush or underwood, from which they, being naked, suffer very much inconvenience. They probably also burnt to encourage new grass growth to attract kangaroos and wallabies, thus making hunting easier because they would know where to find them. The strong ties of Aborigines to the environment on which they so depended is illustrated in their cultural life, the stories of the dreamtime and their art., which strongly feature elements of the natural world around them. The North Shore of Sydney originally had many Aboriginal art works because, with so much sandstone area, it has many caves and shelters in which drawings could be done and an abundance of flat sandstone ledges and cliff-tops for carvings, also known as engravings. Much of this art has been lost through past ignorance as houses and other buildings spread over the Aborigines’ lands. In other places there are no buildings but it is 200 years since the Aborigines were here and the carvings have been eroded away by the weather and can no longer be seen. The Aborigines dealt with this problem by regularly recutting important engravings. Paintings have survived better because they are more protected from the weather in caves and shelters. Preservation of the remnants of Aboriginal art raises some difficult questions. It has been suggested that the carvings which have become very faint should be re-engraved today so that they can be preserved. Others say this cannot be done because it would not necessarily be done in the same way as the carving was originally done and would destroy ‘the original’. Another way of protecting the carvings is to erect a shelter over them but this is expensive, would invite vandalism of the shelters and the carvings, and would affect the feeling of the bush environment in which they were created. As often happens in such cases, nothing has been done and many carvings can no longer be found on the rocks while others can only be seen by using special techniques. Engravings recorded in the 1890s (from files of Lane Cove Library, original source unknown) Note: Only selected aspects of the life of the Aborigines of Lane Cove have been covered here, notably those relating to their use of the environment. Other aspects of the life of Sydney Aborigines, as well as more detail on tools, weapons and fishing methods are covered in the various reference works given for this chapter. 42 European Impacts on Local Bushland 8. EUROPEAN IMPACTS ON LOCAL BUSHLAND 8.1 Early Impacts European settlement of the North Shore has had some major and obvious impacts on its bushland which we can do little about as they happened in the past. These include: * Clearing of almost all of the vegetation communities of the shale ridge tops because these were the flat, fertile areas most suitable for farms and, later, for suburban development. There are now very few examples left of this type of vegetation on the North Shore for us to see what it was like and only a tiny vestige in Lane Cove. * Loss of many animal species from the Lane Cove Valley and, especially from Lane Cove. A 1978 Macquarie University study showed that, of 17 species of mammals found in Ku-ring-gai Chase, 11 were missing from the Lane Cove Valley which would once have been present (see the table in Ch. 5). In addition, this study did not include kangaroos or native cats which are reported to have also once been in the Lane Cove Valley. As the areas of bushland in Lane Cove Municipality are relatively small some of the mammals still found in the upper parts of the Valley, such as echidnas and bandicoots, may now have disappeared from Lane Cove. * Logging of the remaining bushland for large timber trees and for firewood. Cutting out the most valuable timber species may have altered the balance of species in some areas ie. the less valuable trees would now be much more common than previously. * Alteration of burning practices, or the fire regime, which has resulted in changes in the nature of the vegetation communities in much of the remaining bushland. As described in the previous chapter, Aborigines burnt much of the bush on a regular basis. European settlement disrupted this pattern and the eventual result was much worse bushfires than had been induced by the Aborigines because fuel was able to build up to a much greater level. In addition, the lack of fire with which the vegetation had evolved over thousands of years has resulted in changes in the composition of the vegetation communities. In particular there has been loss** of some of the ground flowering plants and shrubs in the dry sclerophyll forest which liked the open conditions maintained by fires. There has also been expansion of plants, such as Pittosporum which is normally a moist gully plant, into areas where it could not expand previously, because it would have been killed by the fires. In non-urban bushland, such as national parks, fires do occur accidentally and fires are sometimes deliberately started to reduce the summer fire hazard and/or for ecological reasons. However, fragments of bushland within urban areas, such as in Lane Cove, are generally too small to set fire to without endangering the houses which surround them. Any fires which start are usually put out as quickly as possible. 8.2 Continuing Problems Bushland in, or close to, urban areas which has managed, usually by fortunate chance or the dedication of some individuals, to survive development is today still under a lot of pressure just because it is close to the built up areas. The worst pressures are felt along the boundary of a bushland reserve. Thus the longer the boundary, in proportion to the area of the reserve, the worse the impacts on that reserve. Unfortunately, all Lane Cove’s reserves are long and thin as they are on the steeper slopes along creek lines by-passed by development. The causes of the pressure on bushland, and the impacts which result, need to be recognised and, where possible, remedial action taken to ameliorate the impacts so that we can protect those little bits of bush we have left. Threats to these remnants come from many sources. ** This refers to loss within a local area. It does not necessarily mean general extinction. 43 The Natural Environment of Lane Cove Alienation and Fragmentation Bushland has always been ‘land-in-waiting’: potential development sites waiting for city expansion to make the fortunes of its owners and developers, The red brick cancer of urban sprawl continually eats away at the bushland areas in, and adjacent to, existing suburbs. Just when an expanding population needs that bushland even more, it is lost forever to development. Bushland has also traditionally been seen as ‘free’ land for all kinds of other uses which then destroy its value as bush. Such alienation includes: * Use of bushland valleys as ‘service corridors’ in which to place sewerage pipes, electricity transmission lines and freeways. In Lane Cove we have sewerage pipes down or across many of the reserves along the creeks (this has had particularly disastrous consequences ~ see Ch. 9.2). There is a high voltage transmission along the Lane Cove River as far as Blackman Park with accompanying sub-station on the Lane Cove side and a transfer station on the Ryde side from which the line proceeds to the city underground. For 25 years it was also planned to put a major freeway down the Lane Cove River from the vicinity of Channel Ten at North Ryde to Figtree Bridge at Hunters Hill. This would have obliterated much of the narrow strip of bushland on the Ryde-Hunters Hill side of the river, as well as destroying the peaceful values of any bush on the Lane Cove side. This part of the Lane Cove Valley Freeway has now been dropped from RTA planning. * Giving pieces of bushland reserves to ‘worthy’ community uses such scout halls and guide huts. We have scout halls in Warraroon Reserve, Aquatic Reserve, Longueville and in Greendale Reserve, Greenwich. * Leasing land to recreational uses such as a golf club or bowling club. This occurred because such recreation fitted into the ‘Open Space’ zoning in which bushland was included. At least some of Lane Cove golf course was created by filling a bushland valley. In the early 1970ls it was proposed to extend the golf course further into the bushland of what is now Bushland Park. Lane Cove’s Bushland and Conservation Society had its origins in the fight to save this bush from such development. Also, Macquarie University Rowing Club has its boatshed on foreshore bushland reserve at Tambourine Bay. * Filling of valleys or wetland areas (often as a way of getting rid of unwanted rubbish), then converting to sports fields or grassed parks, as has occurred at Blackman Park, Gore Creek and Burns Bay. Fragmentation of bushland occurs as development spreads and leaves only small isolated pockets of bush. Larger blocks of bush divided by a road or a service corridor suffer similar problems. As the harmful effects on bush are felt around its edges, the more edges which are introduced, the more animals and plants which are lost. Inappropriate Use There are a number of activities for which people frequently use the bush but which cause a lot of damage. These activities are inappropriate in the very small areas of bush within the urban areas yet, because they are close, they are the areas most likely to be affected. Dumping: Bushland is seen as not really belonging to anybody, or at best, it belongs to ‘the government’. Thus it is used as a dumping ground by those too lazy or too cheap to dispose of their unwanted rubbish properly. Dumping old car bodies and general household rubbish is a frequent and obvious misuse of the bush and industrial dumping is also only too frequent. In Lane Cove a major dumping of used car tyres over a cliff caused enormous and expensive problems for Council recently in getting them removed. 44 European Impacts on Local Bushland However, the most frequent form of dumping is of garden refuse and lawn clippings. Some people dispose of this material in the bush because it is easy to throw it over the back fence or wheel it across the road in a wheelbarrow. Others may feel they are doing the bush a favour by providing it with ‘compost’, In other cases it is not the homeowner doing the dumping but the person hired to do the lawn mowing and paid to dispose of the clippings (properly!). Yet this form of dumping causes some of the worst problems we now have in bushland and some of the worst degradation. These problems are further explored in the next chapter. 4-Wheel Drives and Bikes: The use of vehicles can cause immense damage even when they are driven on established tracks or fire trails. Walking tracks which are intended for light pedestrian traffic are often unable to withstand the impact of trail bikes or BMX bikes and severe erosion may result with tracks becoming unusable by walkers. In Lane Cove bushland, trail bikes have been frequent users of the River Walk to the north of Blackman Park. This is only a narrow strip of bushland and the area has sensitive wetland areas which are easily damaged by bikes. Use of the area by bikes is also dangerous to walkers and the noise is certainly likely to destroy their peaceful walk. Horse Riding: Horse riding is a more peaceful activity than use of vehicles but, unfortunately, can also cause considerable damage in bushland unless carried out on properly constructed trails. Seedlings may be trampled, larger plants damaged, rocks dislodged and tracks eroded, especially on any slope. This tends not to be a problem in Lane Cove as there are few people with land on which to keep horses. Encroachment: Land owners on the edge of reserves may encroach on the reserve are by mowing I to keep it tidy’, for extending the garden, building a barbecue area, incinerator, cubby house, part of the swimming pool, or perhaps a boathouse, in the case of a foreshore reserve. Every small piece lost or altered reduces animal habitat and the variety of plant species. Stealing: Some people still regard bush as public property for the taking – an idea which stems from the past when using the resources of the bush was necessary for survival. However, this is not the case today. Removal of bush rock for garden landscaping deprives small animals of shelter and removes part of the landscape of the bush. Taking ‘dead’ logs and branches also robs small animals of shelter while flower picking diminishes the beauty of the bush for others and means there will be fewer seeds for new plants. 45 The Natural Environment of Lane Cove Cubby-houses: Nailing planks onto trees will damage the trees. Likewise, cubbies at ground level in or near bushes can cause damage through wear and tear of a lot of use in one small area. Use of bush materials to make the cubby obviously destroys trees and plants. Illegal tree lopping: The issue of views from peoples homes is a perennial problem in an area such as Lane Cove where so many people can look out over water and such views are regarded as a valuable property asset. Requests are made of Council to lop the trees on their reserves to maintain views and occasionally the less scrupulous will go into reserves and lop, or even cut down, trees themselves. Cutting down or lopping of trees on a public reserve is punishable by heavy fines for those convicted. Yet frequently, if the offenders had waited a little, their problem may have been solved without drastic action. Many of our native trees such as Eucalypts and Angophoras are open canopied (their branches and leaves are relatively sparse) and, although they block views for a few years when young, they will grow higher allowing sight line through the branches which then frame and enhance the view. Many neighbours disputes would also be solved if such open-canopied trees were planted in locations where a tree is desired but it could affect a view, and those with the view exercised some patience. There are, however, situations where a potential water or city skyline view is completely blocked by intervening bushland. This simply has to be regarded as a worthy view in its own right. Individual property owners cannot expect the removal of trees on reserves, which belong to everyone, for the sake of their private views, particularly if the views did not exist when they bought the house. Pets and Feral Animals Introduced animals are yet another threat to our bushland. These affect the wildlife which we don’t often see. Thus we often do not realise the effect the non-native animals are having on the natives. Although we long ago lost the larger mammals such as koalas, kangaroos and wallabies from Lane Cove bushland, we still have many possums, blue-tongue and other lizards, native rodents and birds. However, many of these can easily fall prey to either feral animals or domestic pets, especially cats. In Lane Cove bushland areas there are feral (or wild) cats, foxes and probably rabbits. The cats and faxes have to prey on the native wildlife to live while the rabbits compete with the natives for living space, or habitat. Lane Cove River State Recreation Area with its plentiful grassy river flats for food and bushland for burrows supports a large population of rabbits. Even well-fed domestic pets are a problem. It is instinctive for cats to hunt and they will even bring back their prize of a bird or mouse (they don’t distinguish between native mice and the imported house variety) proudly to their owners. Dogs on walks through the bush can scare the native wildlife and even hurt them with an overabundance of enthusiasm. Stormwater and Drainage One of the biggest problems faced by bushland next to suburbs is the water falling on those housing areas, from rain or from hoses, which then drains into and through the bush via stormwater drains. Bushland which lies along creeks downslope of the housing as we have in Lane Cove, is particularly vulnerable. 46 European Impacts on Local Bushland Stormwater is picked up from all ‘hard’ surfaces ie. roads, footpaths, paved areas and roofs. ‘Soft’ vegetated areas, on the other hand, absorb water, filter it and let it percolate down through the soil to the creeks relatively slowly. Stormwater pipes usually disgorge into the nearest creek but, if there is no creek, the flow is directed straight into the bush. This stormwater impacts the bush and the creeks in a number of ways: Flooding and Erosion: Storm water increases flooding and erosion of creek banks after heavy rain because a much greater volume of water is going into the creek than prior to development. If there is no creek, the stream of stormwater can cause erosion and gullying of the slope it passes over. Weed Invasion: Where drains disgorge onto a normally dry bushland slope, which usually supports a dry sclerophyll sandstone vegetation, the natural vegetation cannot cope with the increased water and dies. Weeds then flourish in this moister environment with the seeds also brought in by the storm water. Siltation: As any bare soil surfaces are eroded in rain, the soil is taken with the stormwater and deposited in the creeks, obliterating former rockpools and other features, or further downstream and deposited in the bays and the river, creating ugly mudflats (discussed further in Chapter 10). Pollution: Storm water also brings other undesirable clements into the bush and the creeks: nutrients (especially nitrogen and phosphorus) leached from road base materials, from the fertilisers put on lawns and gardens and from the dog excreta in the streets, soaps and detergents from carwashing, oil leaked onto streets from cars and all sorts of litter. The problems of litter, oil and detergents are obvious but the nutrients are also a great problem. Excess nutrients in water cause algal blooms while additional nutrients in the soils of the bush favours weeds and wet sclerophyll/rainforest vegetation to the detriment of the dry sclerophyll bushland. Construction Works Poor planning of development on the edge of bushland and poor construction practices often result in considerable unnecessary damage. This includes physical damage to the trees and bushes, changed soil levels around trees, unstable earth banks left open to erosion and weed invasion and inadequate provision for stormwater drainage. Construction of service roads and fire trails also opens areas in the heart of the bush to weed invasion and soil erosion. Altered Fire Regimes Patterns of fire in the bush substantially different to the patterns with which the vegetation evolved has an impact on the bush which can be significant ecologically, yet go unnoticed by the casual observer. Fires more frequent than the plants are adapted to will kill many species as they will not have matured sufficiently to produce viable seed. Fires less frequent allow the vegetation to grow very densely, encouraging particular species at the expense of those which need the open bush and sunlight to grow and flower. Weed Invasion This is one of the greatest threats to our bushland and is dealt with separately in the next chapter. 8.3 Repairing the Damage and Reducing the Impacts Unfortunately the effects of some of the problems described above are irreversible. For example, we cannot change the size and shape of our reserves to make them more viable and less vulnerable. However, there are a number of problems we can do something about. Alienation and Fragmentation Most bushland which has already been alienated cannot be retrieved (except some leased lands which have not been cleared). However, we can, as citizens, strongly resist the alienation of any further bushland to uses which destroy its bushland values or fragmentation by allowing it to be used as a service corridor. It is too easy to let it go in a piecemeal fashion – a little bit here and a little bit there until there is nothing left. We 47 The Natural Environment of Lane Cove must also resist the argument that it is degraded and ‘might as well be developed’. Most degraded bushland can be restored. In the same way, landowners with a boundary along bushland should be encouraged to appreciate it as a public asset and the values it offers as bushland rather than trying to ‘improve’ it into an extension of their garden or using it as a refuse dump. A little bit· taken along the back of a lot of houses adds up to a large area of bush alienated, fewer places for animals to live, and for people to walk. Inappropriate Uses There is one simple solution to dumping – DON’T! If everyone disposed of their own messes, including garden rubbish, properly and legally there would be no problem. Dumping in bushland is completely antisocial and thrusts the cost of these individuals’ garbage disposal onto the other ratepayers of the municipality. In addition, this costs far more than it would have originally as it is often time consuming and difficult to get at and may involve special pick-up arrangements. As already discussed, use of vehicles, bikes or horses in the bush is not appropriate in the small reserves we have. Trail bikes and vehicles are simply not permitted in the bush, and if any are observed the Council Ranger (see under ‘Lane Cove Council’ at front of white pages) should be rung immediately with details so that he can take action. It is very difficult for Council to stop this type of damage without the watchful help of local citizens. Preventing wilful and unauthorised lopping of trees is also very difficult without the help of locals as the lopper virtually has to ‘be caught in the act’. Residents who live near the bush should regard themselves as ‘honorary rangers’ and if they observe anyone damaging the bush, the Bushland Management Officer or the Ranger should be rung immediately at Council on 9911 3555. (Ranger after hours: 0434 568 604). Encouraging appreciation of bush as a view in its own right, or as framing a view, is also important. Pets and Feral Animals Cats are not compatible with native wildlife. However, as many people enjoy having a cat they should endeavour to protect the wildlife by putting a collar with a bell on their cat. It is difficult for the cat to catch its prey when the prey is warned by a tinkling bell. Even those who do not live near the bush have birds coming into the garden which need protection. One of worst offences against wildlife is to dispose of unwanted kittens by dumping them in local bushland. They become feral cats and live only by killing the native animals. Stormwater and Drainage There are two types of problems associated with stormwater: those of the location and design of stormwater outlets which cause volumes of water to flow over bush slopes,and those of the contents of the stormwater. The first are largely a councilor government responsibility as discussed below. The second group, which impact more on the quality of the water and our waterways, are the responsibility of all members of the community. This second group are discussed in Ch. 10.3. There are a number of things councils can do to ameliorate the impact of stormwater outlets in the bushland: * Install pipes to carry the water right down to the creek or river so that the water is not flowing through the bush. * Install detention basins to catch the water and let it flow out more slowly through a ‘low-flow’ pipe thereby preventing the erosion caused by heavy flows. Lane Cove Council installed two such basins in Warraroon Reserve in 1990 where stormwater discharge from roads along the western boundary was causing gullying and erosion and killing trees. * Direct the flow into appropriate locations by the use of rock walls or other structures. This was done in another location in Warraroon Reserve in 1991, where major storm water pipes collected water from roads and houses and disgorged it straight into the reserve in three adjacent locations. 48 European Impacts on Local Bushland * Where heavy flow is unavoidable but causing erosion, the banks can be lined with stone. If placed irregularly this both breaks up the flow of the water and looks more natural. In 1990 this was been done at the end of Mars Road, West Lane Cove, where torrents of stormwater from the road and part of the industrial area had dug a deep gully down the hill towards the river. * Incorporate much better stormwater drainage design for all new developments which takes into account possible impacts on bushland. Weeds The problem of weed invasion and the solutions are dealt with in the next chapter. BUSH UNDER SIEGE! Our fragments of bush line the creeks of the municipality, hemmed in by housing on the slopes and ridges and subject to all manner of abuses from above. 49 The Natural Environment of Lane Cove 9. WEED INVASION – A SPECIAL PROBLEM 9.1 The Nature and Extent of the Problem The biggest continuing threat to the survival of our bushland reserves as bush is the invasion and takeover of the native plant communities by exotic (non-native) plants. Unwanted plants in a reserve are called weeds whether they are exotic ie. from countries outside Australia, or Australian natives which come from another part of Australia and therefore do not belong. However, the worst problems for our reserves are caused by the various exotic plants, many of which, once they take hold in an area of bush, can expand and dominate the natives very quickly. Weed invasion generally starts around the edges of reserves (the ‘edge effect’ described in chapter 8, again!) and along the creeks. As there is very little of Lane Cove’s reserves that is not along an edge or a creek, all of our reserve area has been, are being, or could be, affected by weeds. Weed invasion is insidious in that it starts in a small way but, unless attended to, it can soon affect large areas without us noticing it happening until it is too late. Growth of plants such as Lantana is particularly vigorous in wet weather, Once weeds dominate an area of bush, it is time-consuming, laborious and expensive to remove them sensitively and restore the bush. Reserves which become dominated by weeds lose values in many ways. Native plant species are lost, sometimes permanently from that area unless replanted. With the loss of native plants the birds and animals which depend on them for food and particular types of shelter are lost from that area, or considerably reduced in numbers. For people, the reserves no longer provide pleasant recreation opportunities. Weeds usually form impenetrable thickets, especially the very common weeds of Privet and Lantana, preventing access and blocking walking tracks. Even where tracks are still accessible, a walk though a jungle of Privet or Lantana is not particularly interesting or pleasant compared to native bush with its variety of plants and animals. It is obviously better to prevent weed invasion in the first place. However, where it has already occurred due to events in the past, it is possible to retrieve the bush and once again make it a haven for native plants and wildlife to live and people to visit and enjoy. 9.2 How Weed Invasion Occurs Plants which are weeds in the bush are also those which threaten the garden. They are plants which, in this climate, in this country thrive and multiply very easily. When their seed or plant cuttings reach the bush, they germinate easily and grow quickly, outcompeting the plants around them to take over. They also have no natural enemies, such as insects or fungal diseases, to attack them and cut them back. They thus thrive just as well in the garden as they do in the bush. There are many exotic garden plants which do not become problems in the bush even though they may have seeds which are dropped there or cuttings dumped. This is because they do not have the strong growth and competitive abilities of the problem plants in this climate. If their seeds do germinate in the bush, they grow only weakly or do not survive at all. The problem plants vary from area to area. This is for several reasons: * Different plants have the competitive edge in different climates where it may be hotter, colder, wetter or drier. * Areas with still or slow moving water bodies, such as dams, lagoons and rivers, have significant problems with water weeds. * Even within suburban Sydney, differences reflect the plants popular in gardens of the area which have overgrown and unwanted parts dumped in the bush. For example, succulents are a particular problem in the coastal areas where they are a popular garden plant to cope with harsher coast conditions. 50 Weeds get into the bush in a variety of ways: Weed Invasion * Birds, as well as other small animals, love those juicy berries which are produced prolifically on many invasive plants, such as Privet, Camphor Laurel, Lantana and Ochna, After eating the berries they deposit the seed far and wide wherever they next perch on a fence or a tree. Thus it doesn’t matter how far away from the bush a plant or tree with berries is, its seeds can easily be transported there by the birds which are so mobile. * Likewise plants with light seed which is dispersed by the wind can reach the bush from considerable distances away. No part of Lane Cove Municipality is far enough away from the bush to be able to have these plants, or berry plants, without the risk of contributing to weed invasion. * Dumping of garden refuse and clippings is one of the biggest sources of weed invasion. It explains why many of our reserves look dreadful where we pass by, with vines climbing up all over the trees and a multitude of non-native plants happily taking over. Clippings which are dumped tend to be of the most vigorous weeds because they also grow rapidly and invasively in the garden. They are also the type of plant which grows readily from cuttings such as Kikuyu grass, Tradescantia, all manner of vines such as Morning Glory, and all types of succulents. * Stormwater brings many seeds into the bush, picking up anything which has fallen on roads, paths or any other surface which drains into the stormwater system. As the stormwater is discharged into the local creeks or straight into the bush, seeds get an easy ride into the bush. This explains why creeks in bush reserves also usually have significant weed invasion. Once the seeds reach the bush, exactly where they establish and take hold frequently depends on other factors. For example, berries and windblown seed would be dispersed by wind and birds or animals randomly over a reserve. Yet invasion occurs at some locations and not others. There are two major conditions which encourage weeds to establish: * Disturbance ie, clearing of an area, or the leaving of any bare soil surface. Weed species then colonise such cleared or bare surfaces more quickly and vigorously than the natives. In our reserves this has most commonly occurred with the laying of services, especially sewerage. Sewerage had to follow creek lines as it works on gravity and pipes were laid through the bush up to 60 years ago. At the time the impact of ugly pipes on the landscape was recognised and they were placed underground with only the round concrete inspection points, or sometimes an aqueduct across a creek, visible. However, the impact of leaving cleared and bare areas in the bush along the route of construction was not realised and, as a consequence, gas, water, and especially sewerage installations, can be located and followed by the bands or pockets of dense weeds. * Unnaturally high moisture and nutrient levels caused by inflows of stormwater from the suburban areas surrounding the bush. Our native species, especially those of the dry sclerophyll communities, are adapted to low moisture conditions and infertile soils whereas the weed species prefer higher levels of water and nutrients. Increasing moisture and nutrients in a normally dry area frequently results in death of the native species whilst the weeds thrive. As the weed seeds are brought in with the water and nutrients in the stormwater it constitutes an explosive little package just ready to take over. 51 The Natural Environment of Lane Cove 9.3 Keeping Weeds Out of the Bush Anyone who has a garden can assist in preventing more weeds from reaching the bush: * By removing from their garden all invasive plants which have berries or windblown seed and, preferably, the problem vines and creepers, some of which have windblown or waterborne seed. See Making Your Garden Bush Friendly (available from Lane Cove Library) for pictures to identify these plants and advice on eradication. * By not planting any of these same plants or any of the problem vines and creepers. The vines and creepers tend to be uncontrollable in the garden requiring a lot of cutting back and creating a problem of disposal. * By NEVER dumping any garden refuse in the bushland – it is unsightly for those who wish to enjoy the bush and it causes enormous problems. Many plants only become a weed problem when clippings are dumped in the bush and these are able to grow and spread. Likewise lawn clippings causes great problems, smothering natives and spreading grasses through seeds and plant parts. All residential properties receive 24 green waste collections per year, as per the waste calendar. Refer to Lane Cove Council’s website for details or contact Council’s Waste Co-ordinator on 1300 655 006 for a waste canlendar. Specifications for collection include: • A maximum of 3 Green bins per property per collection. • No green waste will be collected in any type other than the 240L green bins. * By ensuring that any gardener, gardening or mowing service or tree lopper guarantees to dispose of the material from the garden properly, such as bagging for the Wednesday pick-up or at an authorised tip, eg. a tip docket can be requested before paying such a contractor. 9.4 Restoring the Bush Bush which has been degraded or damaged by the variety of forces which impinge on it can be repaired and restored with commitment of sufficient time, effort and money. Local Councils and Government Authorities are increasingly devoting funds to such restoration work and requiring land developers with bushland to both set aside part of their land in the development as native bush and to pay for its restoration. The first regeneration work done in Lane Cove was by volunteers at Greenwich Point in 1967, In the early 1970’s in what is now Bushland Park, just after it was saved from being buried under fill and turned into a golf course, major regeneration work was done by members of the new Lane Cove Bushland and Conservation Society. This area was an excellent example of the problems and extensive weeding necessary due to invasion along the line of a sewer pipe installation down the creek, yet also of how such an area could be returned to pleasant and viable bushland using regeneration techniques. Volunteers from the Bushland Society also worked in a number of other reserves at this time. Lantana 52 Lane Cove Council was then the first Council in Sydney to recognise the value of bushland by employing bush regeneration teams. This reflects the strength of community response to bushland issues since the 1970s with the Bushland and Conservation Society enjoying continued strong support. Today Lane Cove Council employs a number of people specifically on restoration work, as well as contracting regeneration work’ to private firms. Developers can also Weed Invasion be required to have work done. As part of the redevelopment a few years ago of an industrial site on Stringy Bark Creek the owners, S.C. Johnson, have been required to allocate funds over a 10 year period for the restoration of the bushland area on their site between Stringybark Creek and the Epping Highway. Volunteer groups have again started to work in their local bush under the guidance of experienced regenerators. In the Lane Cove Valley, above De Burgh’s Bridge, the Water Board is spending a large sum over 4 years from the environmental levy paid with water rates, to restore bushland areas along the Lane Cove River and tributary creeks affected by the installation of sewerage lines several decades ago. In restoring a piece of bushland some, or all, of the following may be necessary: * Clearing out of dumped rubbish of all descriptions, often those items difficult to dispose of by regular means eg. cars, mattresses, vehicle tyres. * Clearing loads of silt out of the creek. Such silt comes from erosion of bare surfaces in developed or developing areas or from eroding creek banks. The silt fills in the beautiful rockpools and obscures other lovely sandstone features. * Attending to problems of stormwater inflow where this is causing erosion or damaging bush and promoting weed invasion. * Clearing and replanting of patches where no native plants remain and natural germination does not occur due to lack of good seed in the soil. * Weeding the bush by a method known as bush regeneration. 9.5 Bush Regeneration Bush Regeneration techniques were first developed by two sisters, Eileen and Joan Bradley, in Ashton Park, Mosman in the 1960’s and became known as the Bradley method of bush regeneration (see Bradley, 1988). It was adopted by the National Trust in its reserves in the early 1970’s and the techniques are used by the many bush regeneration teams now working in bushland around Sydney. Some groups, including the National Trust, have modified aspects of the method and other groups follow the original Bradley method closely but the essential aims and techniques remain similar. The Bradleys developed their method and techniques in response to the ineffectiveness of methods of weed control in bushland used at the time, especially by local councils – the ‘slash and bum’ methods. Large areas of weeds would be cleared and either taken away or burnt on the spot. Sometimes the clearings were, then planted with native trees and sometimes they were not. The result of all this activity was a regrowth of weeds a few months later, often worse than previously, whilst the planted areas were unable to survive without a lot of maintenance. Thus the essential aim of bush regeneration is to return bush to a stable weed-free state requiring only very low maintenance to maintain that state (eg. inspection once every six months to a year to remove any new seedlings from bird dropped seeds). This is accomplished by weeding the bush in a very low disturbance way, mainly using hand tools such trowel, secateurs, pliers and knife. The weeds are carefully taken out from amongst the natives with minimum disturbance to the natives or to the soil and soil litter which contain the seeds from which new natives can grow to replace the weeds which have been pulled out. For more detail on bush regeneration and its methods, see Buchanan, 1989 (in references). 53 The Natural Environment of Lane Cove NATIVES OR NOT? Pittosporum undulatum (Mock Orange), Broad-leaf Privet and Lillypilly may easily be mistaken for each other as they have similar glossy green leaves and live in similar environments of moist shady areas. Lillypilly (native) Tree with leaves glossy dark green above, paler green below; small creamy flowers in summer; large fleshy-white pink or lilac berries; smooth greyish bark. Broad-leaf Privet (WEED) Tree with large dark green leaves; dense sprays of strong smelling white flowers in early summer, grape-like clusters of small purple-black berries, smooth grey bark with raised pores giving a bumpy look. Tree with longish, bright green glossy leaves with wavy edges and blisters from leaf miner attack on underside; orange berries; medium size white flowers with a sweet smell like orange blossom. Pittosporum (native) A very invasive exotic creeper, known as TRADESCANTIA (Wandering Jew), looks very similar to an innocent native creeper, called COMMELINA. Tradescantia is generally well known to most gardeners as it climbs over and smothers almost anything in the garden with its thick blanket of fleshy stems and leaves, just as it does in the bush. However, the pretty native look-alike is not invasive but will form a pleasant ground cover. Look particularly for the bright blue flowers to distinguish the Commelina. Tradescantia has fleshy, glossy green leaves and stems, deep green in full shade but lighter in the sun. Leaves feel cold to touch. Flowers are small and white at the ends of the long trailing stems. Commelina’s leaves are mid green, not glossy and are daintier and more pointed than on Tradescantia. Distance between nodes (places where leaves join the stem) is longer. Stems are sometimes purple. Small flowers are bright blue with 3 separate petals. 54 Tradescantia (WEED) Commelina (native) Weed Invasion Formerly even larger trees were taken out by hand but this was very laborious and most bush regenerators now accept the use of glyphosate herbicide (eg. ‘Round-up’, known as ‘Zero’ in more dilute form), carefully and in moderation, to kill them. Once the weeds are removed, patience is required to wait for germination of this seed and growth ie. natural regeneration. Where no natural regeneration occurs, due perhaps to previous removal of topsoil, or filling over it, or to increased water in the soil rotting the seeds, planting may be necessary. However, if planting is required, it is with plants grown from seed from the plants already growing in that reserve and will include a variety of species from smaller shrubs up to the trees. Kikuyu Grass 9.6 Identifying Weeds The main weeds of Lane Cove bushland are listed in Appendix 4. Some of the worst weeds of these are illustrated and easily identified by colour photographs in the booklet Making Your Garden Bush Friendly, or on the poster Bush Enemies (sec references). The best times to identify most weeds are in spring/early summer when they are in flower or in late summer and autumn when they bear distinctive fruits. Care must also be taken to correctly identify a number of the weed species which have native look-alikes before pulling them out. The natives, Lilly Pilly and Pittosporum, are sometimes mistaken for the weed, Broadleaf Privet. Likewise, the native creeper, Commelina, is often mistaken for the invasive weed, Tradescantia (Wandering Jew). Opposite is a guide to distinguishing the natives from the weed species. There are a number of easily accessible locations in the various parts of Lane Cove where a variety of weeds, and their effects on the native vegetation struggling to survive beneath the invasive blanket are readily observed. These sites are all “classic” examples of either weed invasion in and/ along a creek where weed seeds, water and nutrients have come down from the suburban area and/ or along edges of bushland used as dumping grounds for garden rubbish which then spreads. Most noticeable (and disastrous for the bush) at all sites is infestation of vines over everything from rocks and rubbish to the tall trees. Such vines smother and kill the natives if not removed soon enough. Central Lane Cove: The main gully of Lane Cove Golf Course, easily accessed via Longueville Road and Richardson Street West. Weeds can be viewed from the access paths around the gully and between holes. Balloon Vine The golf course was created by filling a bushland valley — the whole floor of the valley in some parts, or one side. This has destroyed much of the original environment as well as severely impacting the bits that are 55 The Natural Environment of Lane Cove left. The fill has eroded into the stream below and by providing a lot of bare dirt has provided areas for weeds to invade. Obvious weeds in the gully are Morning Glory, Balloon Vine, Small-Leaf Privet and Broadleaf Privet, Tradescantia, Lantana, Madeira Vine and Camphor Laurel. There is also some Bamboo and Pyracantha and Willow Trees. The Plant with very large starshaped leaves is Castor-Oil Plant. Native trees can be seen struggling to survive amongst this smothering blanket of weeds although there are also a number of dead trees which have not survived the fill and general disturbance to their environment. The problems of weeds invading along watercourses where it is damp and there are plenty of nutrients is evident here. On the upper slope on the east side of the track on the cast side of the gully is a different mix of weeds with Cotoneaster, Cassia, Lantana, Chinese Privet and assorted other garden plants. Under much of the weed on this slope is a sandstone cliff sporting ferns which could be an attractive feature of the golf course. North Lane Cove: The edge of Mowbray Park near Mowbray Public School. Start at the end of Hatfield Street past the point where the road turns into Hart Street. Continue downhill and turn left and follow a trail at the back of the houses. The first part of the trail which separates the houses from the bushland reserve has been constructed at least partly with fill. Downslope there is a massive infestation of Morning Glory smothering almost everything. Notice that these houses have not oriented their yards or their living spaces to the bush outlook. Rather as you walk along the trail there are incinerators and things people prefer out of sight sitting on the public land beyond their boundary lines – perhaps an indication of their attitude to these bush areas. 56 Weed Invasion Continue along the trail to a small park and follow the trail as it continues behind the houses beyond the park for approx. 75 metres. The same picture exists right along this “edge”: a band of weeds including Small-leaf Privet, Cotoneaster, Lantana, Crofton Weed, Cassia, Blackberry with a few other assorted garden plants such as a Banana Tree and a Flame Tree and various soft leaved low weeds such as Cobblers Peg. Return to the park and cross to Vim Street, turn right and go down to the end of the street. The bush off the end of Vim Street is Mowbray Park but on this edge only a few natives are visible. Instead there is a typical pile of dumped rubbish, bricks etc and dumped garden rubbish including lawn clippings, as well as the weeds Broadleaf Privet, Cassia, Crofton Weed and Mulberry trees. On nearby Willandra Street there are Camphor Laurels (including a very large one) opposite the back boundary of the school. Lane Cove West: along the downslope side of Moore Street Here masses of Balloon Vine are smothering all the other vegetation but there are also Broadleaf Privet, Lantana, Tradescantia, Cotoneaster, Cassia, Bamboo, Arrowhead Vine, Fishbone Fern, Camphor Laurel, and a few other garden plants such as Mulberry and Ivy. The reasons for this invasion are obvious from all the piles of garden refuse across the road from almost every house. The people of this street have kept their yard tidy by dumping their refuse on our bush! The further problem of all this is that over time the seeds and vines keep moving downhill into the good bush below. Perhaps people who dump on the bush don’t deserve to live overlooking lovely bush valleys? Greenwich: The entrance to Gore Creek Reserve on St Vincents Road off River Road Not far past its intersection with Gore Street, the road curves to the right and a gully can be seen on the right smothered in Morning Glory. Walking down the hill, the gully amply illustrates the way that weeds thrive in the moist gully environment where there are also nutrients from the stormwater with seeds, and sometimes cuttings, washed down from gardens higher up the creek. Yet, even on the high side of the road here (normally weeds don’t like steep dry slopes) are plenty of weeds amongst the natives and, just past the last house, the Cobblers Peg influence of gardens can be seen in the great number of seedlings taking off from some well established trees with leaves which look like large Rhus leaves. Also very obvious on the high side of the road are Pittosporum, a native which used to be found in the gullies. Where the slopes are not now burnt (fires kill Pittosporum) it is invading up into these drier areas. After identifying the tree, notice the way its dense canopy creates a ‘closed-in’ effect which stops most of the usual native ground level plants from growing. In this area Balloon Vine competes with Morning Glory for the honours of the largest takeover and there are 57 The Natural Environment of Lane Cove also Lantana, Small-Leafed Privet, Wandering Jew, Ginger Lily and Madeira Vine (look for the Iambs tails starting to form in late summer), Cotoneaster, Camphor Laurel and Asparagus Fern as well as a few Elephants Ears in the creek. The willows also do not belong but they do not spread the way the problem weeds do. Should the Gore Creek Reserve entrance be cleared of its weeds, an alternative, though not as dramatic, site is at the end of Hinklcr Road, reached via Kings Langley Road, where a band of weeds separates a small grassed area from the bush below. The major weed is Lantana but there is also Fishbone Fern, Ginger Lily, Small-Leafed Privet, Cassia, Crofton Weed, Tradescantia, Asparagus Fern, Arrowhead Vine, Camphor Laurel and Black-eyed Susan. Dandelion Morning Glory 58 The Lane Cove – An Urban River System 10. THE LANE COVE – AN URBAN RIVER SYSTEM 10.1 Description The headwaters of the Lane Cove River rise in high ground near Hornsby. With its tributaries it drains a catchment of 93 square kilometres. Much of the catchment is developed for residential purposes, housing a population of 210,000 persons (1980). It also contains small areas developed for light industry and some large undeveloped areas of native bush and other vegetation (eg. grassed picnic areas of Lane Cove River State Recreation Area). Of the river’s total length of some 25 kilometres, the upper half is freshwater, impounded by a weir near Fullers Bridge. The lower half is saline and tidal. The Lane Cove River is the largest tributary of the Parramatta River, which it joins at Woolwich. The river is joined by a large number of tributary creeks along its length. These drain the various corners of the catchment in a typical dendritic pattern (so named after the dendrites, or nerves, in the body but also resembling the branches of a tree). The erosive work of the river and these tributaries has created the rugged ridge and valley topography of the entire catchment area. Although there are some large chunks of undeveloped bushland in the upper catchment, by far the greatest part of the catchment is developed. This creates many problems for the creeks and the river, discussed in 10.3. For many aspects and issues pertaining to the river we must look outside just the local area to understand what is happening and to devise solutions to problems. For example, much of the pollution in the river along our boundary and the silt deposited in our bays and our part of the river comes from much further upstream. 10.2 How People Have Used the River System Aborigines The Aborigines used the Lane Cove River as a major source of their food, particularly a variety of fish and shellfish. It was probably also a travel route, rather than just a barrier to be crossed, and they were skilled in making and using their canoes. The creeks provided the Aborigines with their fresh water for drinking. Exploration Some of the earliest exploration of the North Shore was via the river. In February, 1788 a survey party led by Captain Hunter took depth soundings along the lower river as far as the present Figtree Bridge. In 1789 there was exploration further up the river as far as the head of navigation which was not far from the present De Burghs Bridge. Our evidence for such exploration comes from the naval charts of the time which show the river upstream sufficiently accurately to indicate explorers actually reached this far (see next page). However the twists and bends of the river above Linley Point seem to be shown more accurately in the 1790’s than the lower portion of the river, downstream of Linley Point, was to be shown for nearly 100 years. All of the early maps of the river (here and in the nest pages) display significant distortion of the size and shape of the bays, coves and peninsulas of the lower river until the survey of 1888. We can only speculate whether such inaccuracy was due to poor mapping techniques or to the fact that as an isolated, mainly unsettled area, Lane Cove was not important enough to map accurately. Early European settlers relied almost exclusively on the river as a transport route. The North Shore was very wild and undeveloped for many decades and traversing the area with all its valleys was extremely difficult, except along the main ridge (now the Pacific Highway but originally called the Lane Cove Road). Even on this main ridge the “road” was a frequently impassable track until the 1850s and not much better for the next 30 years. Thus the river was a major mode of transport route for most of the 19th century. 59 The Natural Environment of Lane Cove EXPLORING THE RIVER Above is part of a chart of Port Jackson drawn between 1788 and 1792 by Lt. William Bradley, a naval officer on the First Fleet. Bradley explored the harbour with Captain John Hunter who also drew charts of their surveys. Their charts were the first ever drawn of the harbour and show the first explorations of most parts of its coves and rivers. From the charts can be seen how far the Lane Cove was explored in the first few years of the colony. Timber There were many valuable timbers in the forests of the North Shore, especially the tall forests of the ridges, and one of its earliest economic activities was timber-getting. Sometime between 1805 and 1809 a government ‘sawing establishment’ was established in what is now West Killara. Convicts cut the timber from the substantial forests of the area and it was taken down a track (now Fiddens Wharf Road) to be loaded onto boats and sent into the town. By 1819 the timber which the government was interested in had diminished in this area and the government activities moved further up the catchment to the Epping/Eastwood area from which the timber was taken down to the Parramatta for transport. However, there was still a lot of timber to cut for various purposes and boats continued to ply the liver laden with timber for several decades. Much of it was loaded from the old government wharf at West Killara, which 60 The Lane Cove – An Urban River System MAPPING THE RIVER Survey of Port Jackson 1822 Survey of Port Jackson 1857 Survey of Port Jackson 1888 Using the charts of the lower river in this chapter, compare the way the features along the river are drawn with a present map of Lane Cove. Look at the bays: Tambourine Bay, Burns Bay, Woodford Bay and Gore Creek’s cove; and the peninsulas: Linley Point, Riverview, Longueville, Northwood and Greenwich. (Remember that the mouth of Gore Creek was filled this century.) 61 The Natural Environment of Lane Cove came to be known as ‘Fidden’s Wharf’, after Joseph Fidden whose boat carried much trade on the river for many years. There was still a procession of boats laden with firewood to be seen coming down the river in the 1850’s bringing timber cut from the Field of Mars Common which stretched along the west side of the valley from Boronia Park to Cheltenham in an area of approx 6,000 acres (2430 ha.). Farming As the farmers replaced the timber-getters, many settlers came to farm the various alluviall1ats all along the river right upstream to the present De Burghs Bridge area. These farms relied on river transport to get goods in and out especially the bigger farms, such as those around the present Fullers Bridge where the produce from prolific citrus and pear orchards had to be got to market. For many years farmers on the ridge also found it quicker to bring their goods down to the wharves on the river, rather than make the journey on the Lane Cove Road, then have to take the punt at North Sydney. Industry When the farms began to decline around the beginning of this century the demands of industry for river transport increased. In fact, many early industries in Lane Cove located near the water due to the availability of the river for transport. The earliest of these were the tanneries, producing belts and other leather products, established from about 1859 on the creek running into Burns Bay, which became known as ‘Tannery Creek’. Another factory, manufacturing wood pipes, was also located on Burns Bay. A tannery and boiling down works was established on a bend of the river next to the present Epping Road Bridge in about 1882. By 1894 this had been replaced by a cornflour factory (which has grown and expanded over almost 100 years and still occupies the site, albeit under different ownership). Both factories relied on the river to cheaply transport raw materials to the site and finished products out as there was virtually no access overland apart from rough tracks. In 1912 paper board mills were established on Stringy Bark Creek and the lower part of the creek and its entrance were modified to create direct boat access right into the mills. The mills were destroyed by a bushfire in 1928, ironically because the fire had cut road access and neither the harbour’s fire tender nor fire engines loaded on punts could get upriver past Figtree Bridge because it was low tide and the silted river was too shallow. Other industry followed in Stringy Bark Creek: Robert Corbett chemical industries, later taken over by CSR. However, for these industries, and the cornflour mills, the advent of motorised lorries and road links which enable transport of raw materials and products ‘door-to-door’ without unloading, together with almost complete silting up of the channel in some places, gradually spelt the end of industrial river transport above Figtree Bridge. However, one major industry, which began in Greenwich in 1903, is still very much tied to its water transport: the oil storage and distribution depot established by John Fell and Co., now owned by Shell. Passenger Transport For the first 40 – 50 years of the colony, settlement was sparse and scattered around an extensive harbour. Water transport was vital with the lack of adequate roads and bridges yet there were not enough settlers in anyone place to support conventional ferry services. Thus there were many watermen plying the harbour with small boats transporting passengers one, or a few at a time, to individual destinations. The official rate for such a trip in 1841 to the wharf at Woodford Street, Longueville was four shillings and sixpence. By the 1850s the population of Lane Cove and Hunters Hill was sufficient for the Joubert family of Hunters Hill to establish a regular ferry service from the city to the lower Lane Cove River. The Jouberts ran this service until 1906 when they sold it to the Balmain New Ferry Company and, with several other changes of ownership, there is still a ferry service on the lower river today. In the 1890s the fare on the ferry was one shilling single and over many years the service called at up to nine wharves from Greenwich to Figtree which became the terminus when the first Figtree Bridge was built in 62 1884 (the wharf was located where the southern end of the new Figtree Bridge now stands), The Lane Cove – An Urban River System With the prevalence of cars today, restricted services call at Greenwich, Northwood, Woolwich and the Alexandra St. Wharf, Hunters Hill, thus still providing a pleasant and leisurely way to reach the city for residents of Lane Cove and Hunters Lane Cove River Ferry, S.S. Northcote Hill, even if not reaching as far up the river as previously, nor as frequently. A private ferry service also ran to and from Longueville twice per day until early 1991 but even it had to cease operation for lack of customers with more people working varied hours rather than the old “9 – 5”. In 1908 some leading citizens of Lane Cove and Hunters Hill decided to open up the river above Figtree with a motor launch service to carry passengers, mail, livestock and merchandise. The Upper Lane Cove Ferry Service ran a feeder service from the steamferry terminus at Figtree to Fiddens Wharf at Killara, calling at about eight wharves on the Lane Cove, Ryde and Chatswood banks on the way. Although this service used flat bottomed launches, they still began to have trouble getting right up the river. Eventually the service was sold in 1918 to the owners of ‘Fairyland’, a picnic grounds on the river opposite Mowbray Park. The students of St. Ignatius College at Riverview also relied on the river for transport, almost exclusively, for many years. The first students attended in 1880 and from that time would arrive and depart by boat and the school’s own wharf. The countryside between the school and the centre of Lane Cove was very rugged and the river was much more convenient access to the school for students coming from a variety of locations. Special ferries would also be chartered by St. Ignatius and St. Joseph’s College (Hunters Hill) to transport footballers and barrackers between the colleges and from the colleges to other parts of Sydney for ‘away’ games. Recreation In the 1880s a small boat took passengers on excursions up the river from the ferry terminus at Figtree. From this grew extensive use of the river for recreation. At the turn of the century the Lane Cove River was highly regarded as a beauty spot and became increasingly popular especially as a “poor man’s” recreation spot. It was described most fulsomely in newspaper articles of the 1890s and early this century (see next page). This recreation was based on row boating and picnicking. Picnickers could reach the river by ferry services which came from various parts of Sydney on weekends and public holidays and either visit one of the two major ‘pleasure grounds’ on the river or hire rowboats from Figtree and row up river, Slopping at the many little reserves and picnic spots along the way. A favourite trip for the energetic was to row right up to the Blue Hole, the head of navigation of the river, close to the present De Burghs Bridge. After the weir was built and the Lane Cove River National Park opened in 1938 rowboats could only go as far as the weir but the Park provided greatly increased opportunities for picnics along the banks of the river. There were two more developed picnic areas, known as pleasure grounds, with various facilities and organised activities, such as refreshment rooms, dances in an open air dance hall and equipment for rides. ‘The Avenue’ pleasure grounds was located in what is now the foreshore areas and playing fields of Hunters Hill High School while ‘Fairyland’ (initially known as ‘The Rest’) was located further upstream opposite eastern Mowbray Park. Despite the difficulties for boats navigating the river at low tide, Fairyland would be crowded with launches from all over Sydney on holidays, as illustrated opposite, and the proprietors also ran their own boat to Figtree to meet the steam ferries. Picnic based recreation continues to be an important foreshore use but picnickers now gct to the picnic spots by car. However, the parts of the river with suitable picnic spots are in two distinct sections: downstream of Figtree Bridge where the Lane Cove side, in particular, has a number of nicely developed reserves, and the 63 The Natural Environment of Lane Cove “A VERITABLE FAIRYLAND” 80 to 100 years ago the Lane Cove River was becoming very popular as a beauty spot and a good place for recreation such as picnicking and boating. People would catch the ferry as far as possible: to Figtree, or even as far as Killara (from 1909 to about 1916). They then hired a rowboat to go further up river. Here are some descriptions of the river written in the newspapers at the time about trips up the river: “Indeed it is doubtful whether there is any river more picturesque than that of the Lane Cove River from the bend which conceals the Parramatta to the point where it becomes a tiny streamlet, dancing and leaping among the grey masses of rock and time-worn boulders which seek to impede its course.” “It has taken us but an hour, and the distance, by the varied scenes which break at every corner and turn, give one the feeling of having travelled a full score of miles. It is a place for a landscape artist to rave about, it is a place for a poet to dream himself into ecstasies over.” The river was described as a “veritable fairyland” with “visitors being struck with the wealth of beauty spots and the diversified character of the scenery”. About halfway up the river from Figtree: “The Rest is the first place reached where a halt may be made for a cup of tea. ....Here are moored half-a-dozen row boats, and there are parties of young people scattered about in groups reclining here and there on the sward enjoying the soft serenity of it all. It is a long pull, but if the tide is taken both ways is not so laborious a task as it looks.” “On you wind, free for a day in Nature’s own domain...A suggestion here and there of rock-faced precipices lends its touch of variety and mild romance; while, especially at high tide, the more commonplace mangroves add their quota of rural effect.” From near the present Fullers Bridge: “the banks for the space of a few miles are lined with fruit trees, the overhanging branches often touch the glassy water and you may pick fruit without even getting out of the boat”, Past the orchards: “The scene now changes and becomes fairy-like indeed, trees dropping their boughs in the crystal stream, and bulrushes, waratahs and Christmas bushes extending to the water’s edge.” Arriving at Fairyland for a day’s outing 64 The Lane Cove – An Urban River System Lane Cove River State Recreation Area much further upstream. In between, mangroves block most of the shoreline and there is only Blackman Park where the picnic areas are not on the edge, or in view, of the water. Boating also remains a common pastime on the river but today they are frequently motorboats and activity is limited to sightseeing. There are few places to stop a boat and picnic or walk above Figtree as was once popular. Water skiing on the river has become common in recent years but causes a number of problems. The water ski boats come up river and base themselves at one of a number of small beaches along the river upstream of Figtree Bridge (there is one at Blackman Park). However, the river is too narrow to safely ski in a number of places and a skier was killed on the river in the mid-1980s. The constant noise of the power boats adversely impacts the residents who live near this section of river and the boats are detrimental to other, quieter boat uses of the river such as canoeing. Canoeing is perhaps the modern equivalent of the rowboats of days gone by, both above and below the weir. A common trip is to launch the canoe just downstream of Fullers Bridge and paddle downstream with the tide. Rowing Regattas held on the river, mainly associated with the two colleges, also attracted people from all over Sydney and were big events on the river. Today rowing is still an important sport and, in addition to St Josephs and St Ignatius Colleges, Sydney and Macquarie Universities’ rowing clubs and the North Shore Rowing Club are based on the river. The long hulls of boats from all these clubs can frequently be seen practising up and down the liver. Stormwater Disposal All water which falls on any hard surface such as roads, roofs, carparks and footpaths in the entire catchment of the river ends up in the river. This water, known as urban stormwater, is drained from hard surfaces into storm water drains which go underground to the nearest creek valley where they discharge into the bush or into the creek itself. The problems thus caused for the bushland were discussed in 8.2. This chapter considers the problems caused for the waterways. Whilst it is natural for water falling on a catchment to drain to its river, urban stormwater is highly polluted. As it washes everything off all hard surfaces it contains the substances which fallout from car exhausts and other air pollution, dog faeces, litter, grease and oil, detergents from car washing etc. People often see the nearest stormwater drain as a convenient disposal point for any awkward liquids they have, such as oil from cars and even industrial waste. By doing this they are not just using the drain for disposal, but fouling our waterways which we use for recreation. Sewage Overflow Sewage from the northern half of Sydney east of Blacktown is taken across the city to North Head for treatment and marine disposal via a major sewerage line, the Northern Ocean Outfall Sewer, known as the NOOS. This crosses the Municipality of Lane Cove passing first under the Lane Cove River in tunnels dug through the sandstone. In Burns Bay and Gore Creek valley viaducts carry the NOOS across the valleys. When it rains, extra water always gets into sewerage systems through cracks in pipes and wrong connection of stormwater pipes to the sewerage lines. The NOOS was built in the 1920s and, whilst designed to accommodate a wet weather flow much greater than normal dry weather flow, it is now running at nearly full capacity in dry weather and cannot accommodate the increased flow in wet weather. Thus the system overflows and the overflow points are on major creeks and rivers, including the Lane Cove River where the NOOS crosses a short distance upstream of Figtree Bridge. Obviously this adds considerably to the pollution load in the river in wet weather when it already carries much polluted urban stormwater. Flushing by the tides eventually disperses the pollution. 65 The Natural Environment of Lane Cove 10.3 Reducing Adverse Impacts on Waterways The major problems experienced by our waterways are: * Flooding and the erosion of creek banks * Pollution of creeks by urban stormwater and pollution of the river and some creeks by sewage and urban stormwater, * Siltation: blocking of creeks and obscuring of their lovely rock features by silt, loss of bays to mudflats and increasing shallowness of the river due to silt deposition. In Lane Cove we receive the results of erosion way up in the catchment as the silt is carried down and deposited in our part of the river. The Lane Cove River near Figtree Bridge, and most of the bays downstream: Burns Bay, Tambourine Bay and Gore Creek’s cove, are significantly affected by the deposition of silt and the build-up of unsightly mudflats. These mudflats are not only unattractive at low tide but they prevent the launching of boats and impede navigation, as well as exacerbating pollution by decreasing the depth of water and the flushing effect of the tides. Dredging is a very expensive operation. Much of the river from Fullers Bridge to near Figtree Bridge was dredged in the 1950’s and 60’s but as a commercial operation to gain the sand which lay beneath the mud. The sand is now gone and a commercial operation will not be possible again. The first of these problems needs to be tackled by government, particularly the local council. As an initial step, Lane Cove Council had a hydrology study of its bushland completed in 1986 to examine the problems associated with stormwater, drainage and creeks in the bushland A number of its recommendations to ameliorate these impacts have since been implemented or constructed. For the other two major problems, it is mainly up to individuals to play their part in the solutions. We all have a responsibility to act in a way which will not create, or worsen, the problems. Flooding and Erosion of Creek Banks This is largely caused by the much greater flows of water pouring into creeks after rain. Water from hard surfaces is collected by stormwater drains much more quickly than water which falls on soil or vegetation percolates down through the soil and into the creeks. Thus we now have more water hitting bushland slopes and the creeks all at once with great erosive power. The solutions are: * Creation of areas which can hold the collected water after rain (called detention basins) and let it out slowly through small diameter pipes, known as ‘lowflow’ pipes. In developed areas the basins may be carparks, grassed reserves or other open space. 66 The Lane Cove – An Urban River System Such areas and pipes are being required by Council in new developments but are more difficult to create in older areas. * Lining of creek banks with natural stone where a large flow of water is unavoidable. * Construction of stilling basins in creeks to reduce velocity of water and thus its erosive effect (scour). As the rushing water flows in, it is first stopped as it fills the basin, then slowed by hitting the water body. * Including grass and plantings wherever possible in developed areas rather than hard impervious surfaces. Home owners should consider this factor when planning landscaping and keep paved areas to a minimum eg. driveways with part grassing are preferable to full concrete. For developments requiring plans for exterior areas (units, townhouses, industrial and commercial) Council now considers the balance of ‘hard’ and ‘soft’ surfaces before giving approval. Pollution from Urban Stormwater Much of the pollution in urban stormwater comes from individual sources which governments can do little to directly control. Rather, it is up to each individual to act in an environmentally responsible way and help protect our waterways. Consider the creeks and waterways beyond your backyard in these ways: * Do not wash cars (or anything else) in driveways or anywhere where the soapy water runs into gutters and storm water drains because this just ends up in the creek, river or bush. Instead, wash the car on the lawn where washing water can be absorbed and the water useful rather than wasted. * Try to ensure your dog does not defecate on roads or footpaths. If it does, a ‘pooper scooper’ and paper bag would be handy to remove the problem to a bin. Doggie ‘do’s’ cause faecal contamination of the water and provide nutrients, thus encouraging weeds in the bush and algal blooms in water. * Be sparing with fertilisers and pesticides in the garden. Rain can wash it off and into drains where it doesn’t do the garden any good and it pollutes the creek or river. * Don’t leave piles of leaves, lawn clippings or other rubbish in the gutters where it can then wash into drains causing blockages and pollution. * Dispose of all difficult liquids, such as unwanted oils, paints, garden chemicals etc. at a licensed Waste Disposal Centre. * Anyone who sees, or knows of someone dumping chemicals, oils, greases or other industrial wastes into stormwater drains, or the sewer is encouraged to ring Lane Cove Council’s Environmental Health Officer on 9911 3626. Pollution from Sewerage While it would seem that building bigger capacity sewerage lines is a government problem, this is actually an action of last resort as it would be horrendously expensive (sending our water rates skyrocketing) and it would disturb many residential areas. Before embarking on such a scheme we should first make the existing lines work efficiently. At present many homes and other properties have downpipes connected to the sewerage system rather than to the stormwater Access hole Normal sewage level Sewerage Overflow Point Wastewater and stormwater find their way into the sewerage system causing overflow Stormwater and raw sewage overflow causing environmental pollution 67 The Natural Environment of Lane Cove system or drainage pit. This is one of the major causes of extra volume in the sewer line when it rains, thus overflows occur. It is obviously inefficient to have sewerage capacity taken up just with water and then have raw sewage overflowing into creeks and rivers. The solution is to ensure that all downpipes go into the stormwater system. The Water Board is pursuing a program of smoke testing to determine where the problems are, but it would be preferable if homeowners took action themselves. Smoke testing involves putting smoke into the sewer system in the street and seeing where it comes out. If it billows out the top of a downpipe, there is obviously a connection! Siltation Rain washes soil off any bare surface. No matter where this happens in the municipality it is then carried downhill, through storm water drains to creeks and rivers. The results of 200 years of settlement and clearing are all too clear at low tide with extensive mudflats in the river, especially around Figtree Bridge, and in the bays. In the bays, which were once the open mouths of creeks the process has been the growth of mudflats, followed by colonisation of the flats by mangroves, then sometimes filling over the mangroves to create playing fields or grassed reserves. The last has occurred in Burns Bay Reserve, Blackman Park and Gore Creek Reserve. In Tambourine Bay the mudflats and the mangroves have grown but not been filled. In the filled bays the process has begun all over again with the build up of more mudflats beyond the seawalls of the grassed reserve. The solution is simple in concept but difficult to execute. It is simply to prevent any silt washing off any building, development or landscaping site in the whole of the catchment of the Lane Cove River and to minimise erosion on bush tracks. This requires considerable effort by many people and authorities. Anyone, be they individual, government body, business or developer who clears vegetation, disturbs soil or places fill must be aware of the problem of silt run-off and take steps to prevent it. The adequacy and effectiveness of the prevention measures have to be monitored and steps taken to enforce their usc, if necessary. This role would mainly be taken by local Councils who give approvals for building and inspect building sites. For more details on many of the issues discussed in this chapter, including, pollution, siltation and the past, present and future uses of the river, sec McLoughlin, 1985. 68 The Lane Cove – An Urban River System CLEAN CREEKS AND RIVERS BEGIN AT HOME Report any pollution incidents including dumping of any waste materials, chemicals etc. into stormwater or sewer to NSW EPA Environment Line 131 555. Garage and shed Unwanted household or garden chemicals should never be placed down the sewer or the stormwater drains. Check with your Council for local disposal depots if you have particularly large quantities. Fences, gates and retaining walls Gullies Makesure your household gully grate (usually outside the kitchen or bathroom) is above ground level so rain water doesn’t flow into it. Gutters and downpipes Roof gutters and downpipes should connect to stormwater drains not the sewer; illegal stormwater connections lead to sewer overflows. Fertilisers and pesticides Choose fence, gate or retaining wall designs which take into account water flow. Managing the flow of stormwater on your property can avoid damage. Minimise use of fertilisers and pesticides. These chemicals are easily washed off the garden by stormwater and end up in local creeks. Lawn care Coring your lawn lets it breathe and aviods compaction. Coring also helps water soak in, reducing runoff. Garden clippings Start a compost heap. Vegetable scraps, tea leaves and grass clippings make excellent compost which is ideal fertiliser for gardens. Footpaths and streets Paved areas Keep paved areas to a minimum. If you are constructing a path or paving a patio or pool surround, choose a design or surface which lets stormwater soak in. Washing the car Wash your car on a grassy area. Sudsy water which flows down the gutter ends up in your local creek. Increased nutrients from detergents cause a lot of problems in our waterways. Cars, trucks and motor bikes If you do your own oil change don’t pour oil down the gutter or into the ground. Dispose of the oil in a sealed container in the garbage or in a special Council cleanup. Any rubbish, leaves or dog droppings in the street end up in stormwater drains causing blockages or pollution problems. Stormwater grates Everyone can help by keeping stormwater grates clear of litter, leaves and stones. Blocked drains can lead to local flooding. 69 The Natural Environment of Lane Cove WHO USED THE RIVER – THEN?
