It is essential reading for staff of Local Land Services (LLS), National Parks and Wildlife Service part of the Office of Environment and Heritage (NPWS) and all agencies involved in vertebrate pest control. It is intended to promote uniform standards for vertebrate pest control throughout the State including guidance on procedures and requirements for storage, use and supply of vertebrate pesticides. This manual acknowledges that many of the procedures and practices are primarily designed for LLS and Authorised Control Officer (ACO) staff. Other government agencies, particularly NPWS staff may have operational procedures which differ from those proposed in this manual. Such practices are acceptable as long as ACOs are compliant with all the NSW legislative requirements. This manual provides the Introduction, Legislative, Administration and Poisons and Fumigants policy requirements for pest animal management as prescribed in the Pesticide Control Orders gazetted under the Pesticides Act 1999. Further information on pest animal biology and behaviour are available in a Biology, Ecology and Management of Vertebrate Pests in NSW appendix to this manual.

It addresses the development of local and regional pest management planning using fundamental pest planning principles. F R A M E W O R K O F V E R T E B R AT E P E S T M A N AG E M E N T I N AU S T R A L I A Whilst the vast majority of pest animal managers operate at a local or regional level, it is useful to understand the way that strategic pest animal management is conducted. An understanding of broader pest animal strategies at both the national and state level may provide a better understanding of, and opportunities to: a. target key areas to facilitate the control of existing species and surveillance for new ones b. implement control at more appropriate times or integrating local control with larger scale control activities such as catchment, state or territory based programs c. adopting long-term planning within a national or state framework d. more effectively communicate among stakeholders e. seek funding and support for local or regional control programs which demonstrate integration with state and national strategies. AU S T R A L I A N P E S T A N I M A L S T R AT E G Y The Australian Pest Animal Strategy, agreed to by all Australian governments, sets out how governments work with each other, and with business, industry and the community to manage the issues and problems associated with vertebrate pest animals in Australia. In overview, the Australian Pest Animal Strategy establishes key objectives and actions that aim to prevent the introduction and spread of new pest animals in Australia and assist in managing the impacts of those that are already established. The Vertebrate Pests Committee is responsible for monitoring the implementation and review of the Australian Pest Animal Strategy. The Vertebrate Pests Committee reports to and operates in accordance with Terms of Reference defined by the National Biosecurity Committee. Each State and the Australian Government has membership on the Vertebrate Pests Committee, and the Invasive Animals Cooperative Research Centre, Commonwealth Scientific and Industrial Research Organisation and others have Official Observer status. INTRODUC TION 7 The Vertebrate Pests Committee convenes a number of Technical Working Groups (which may include Vertebrate Pests Committee members) to advise it on technical matters. These include the National Indicators Working Group (monitoring and mapping of pest animals) and the Vertebrate Pest Animal Welfare Working Group. For a copy of the Australian Pest Animal Strategy go to: www.apas.net.au N S W I N VA S I V E S P E C I E S P L A N ( 2008 – 2015 ) The principal strategies for managing invasive species (including: weeds, vertebrate and invertebrate pests) in NSW are outlined in the New South Wales Invasive Species Plan. The Plan aims to prevent new incursions, contain existing populations and adaptively manage widespread species. The goal is to foster a cooperative culture where all relevant parties contribute to the aim of minimising the impacts of invasive species in NSW. The Plan outlines a coordinated response by stakeholders to minimise the impacts of invasive species in NSW using a risk-based approach. The Plan guides current and future investment in invasive species management and includes existing and planned activities as well as new projects that will commence as agencies redirect resources in response to the priorities in the Plan. The NSW Invasive Species Plan identifies four goals to realise its vision: Goal 1: Exclude – prevent the establishment of new invasive species. Goal 2: Eradicate or contain – eliminate, or prevent the spread of new invasive species. Goal 3: Effectively manage – reduce the impacts of widespread invasive species. Goal 4: Capacity building – ensure NSW had the ability and commitment to manage invasive species. A copy of the NSW Invasive Species Plan can be downloaded from: www.dpi.nsw.gov.au/agriculture/pests-weeds/nsw-invasive-species-plan N S W P E S T A N I M A L CO U N C I L The Pest Animal Council consists of representatives from across NSW representing a broad range of stakeholder groups involved with pest animal management. The Council’s goal is: The use of environmentally, economically and socially acceptable pest control through the adoption of well coordinated best practice programs. VERTEBRATE PEST CONTROL MANUAL 8 INTRODUC TION To realise this goal the following objectives have been identified: Objective 1: To identify all pest animal species and their impacts, and prioritise resource allocation. Objective 2: To encourage the development and application of best practice, cost effective and humane control methods. Objective 3: To identify deficiencies in and disseminate knowledge about integrated pest animal control to both land managers and the public. Objective 4: To provide advice on pest animal control to Ministers and non-government organisations. Objective 5: To improve the cost efficiency of pest animal control or eradication by improving liaison and co-ordination and reducing duplication across government and non-government agencies. Objective 6: Report and advise on Government decisions on pest animal control to constituent bodies. RESPONSIBILITIES FOR V E R T E B R AT E P E S T M A N AG E M E N T I N N S W N S W Depar t m ent of Pr imar y I n d u stries The NSW DPI has an enabling role for vertebrate and invertebrate pest animal management in NSW. Its primary responsibilities are in administering invasive species and biosecurity legislation, policy, training and education. Lo cal Land S er vices ( LLS) Local Land Services came into force on the 1st of January 2014 and are formed under the Local Lands Services Act 2013 (LLS Act). Local Land Services brings together agricultural production advice, biosecurity, natural resource management and emergency management into a single organisation. In relation to pest management LLS participate in on-ground detection and control of declared pests and plague locusts in NSW. This work includes giving advice on pest animal management techniques, assisting land managers to develop vertebrate pest management plans and cooperative management programs. LLS may have Catchment Action Plans still in operation from former Catchment Management Authorities which include funding and support for vertebrate pest species management. See also below under Local Land Services Strategic Plans information on planning processes under way. Env i ronm ent Protec t ion Au th o rit y The Environment Protection Authority (EPA) regulates the use of all pesticides in NSW, after the point of supply under the Pesticides Act 1999 and its regulations. This involves developing and enforcing pesticide use laws for NSW, such as producing Pesticide Control Orders (PCOs) which stipulate how vertebrate pesticides which are restricted chemical products (RCPs) can be used to reduce exposure and minimise impacts on the environment, non-target plants, non-target animals, people and trade. The EPA also provides information and advice on management of pesticides. INTRODUC TION 9 O ffice of Environm ent an d Heritag e National Parks and Wildlife Service (NPWS) NPWS is responsible for managing National Parks and Nature Reserves for the protection and conservation of biodiversity in NSW. This involves the development and implementation of Regional Pest Management Strategies which prioritise programs and specific actions for invasive species including vertebrate pests on lands managed under the National Parks and Wildlife Act 1974. NPWS also works with other government agencies and the community to protect biodiversity and agriculture on neighbouring private lands. It also provides advice and undertakes species recovery, threat abatement and community education programs and research to ensure that threatened species are protected. Threat abatement may involve the development of plans such as the Threat Abatement Plan for Predation by the Red Fox (Fox TAP). L and m anager s, commu n ities an d sp ec ial interest gro u ps All private land managers have an obligation under the LLS Act to manage declared pests on land they own, occupy or manage. Acknowledgement should be given to the important role of community volunteers and special interest groups in the management of vertebrate pests. These individuals and groups provide hundreds of hours each week assisting in the management of private and public lands through direct vertebrate pest control and monitoring activities. Crown Lands Crown Lands, a Division of NSW Trade and Investment, is a significant land manager in NSW administering Crown land. Crown Lands develops and implements invasive species management strategies on land under its direct control. It also supports activities undertaken by community groups and other stakeholders that manage land on their behalf. G am e L icens ing U nit The Game Licencing Unit within NSW DPI is established under the Game and Feral Animal Control Act 2002 (amended 2014) (Game and Feral Animal Control Act). This Unit may be utilised to harness the efforts of licensed, accredited hunters to assist in controlling vertebrate pest species. Local gover nm ent and o th er pu b lic lan d man ag ers All public land managers including Local Councils and County Councils have an obligation under the LLS Act to manage declared pests on land they own, occupy or manage. I ndus t r y Industry has three main roles in invasive species management: (a) managing pests on land and in aquatic environments used for production; (b) managing the trading potential or known invasive species used for, or held by zoos and collectors and (c) not providing vectors or pathways for invasive species establishment through movement of goods, produce and equipment or related activities. VERTEBRATE PEST CONTROL MANUAL 10 INTRODUC TION LO C A L L A N D S E R V I C E S S T R AT E G I C P L A N S The LLS Act under Part 4 specifies the requirements for both State-wide and Local Strategic Plans. Each LLS is required to develop a Local Strategic Plan under Part 4 of the LLS Act. These strategic plans must address the state priorities for Local Land Services. One of these priorities is biosecurity, including animal pest and disease and plant pest and disease prevention, management, control and eradication. The purpose of the strategic plans is to set the vision, priorities and overarching strategy for local land services at the state and local level, with a focus on appropriate economic, social and environmental outcomes. The State Plan will have effect for a period of ten years whilst the Local Plans will have effect for five years. P R I N C I P L E S O F S T R AT E G I C P E S T A N I M A L M A N AG E M E N T I m p ac t s of ver tebrate pests The focus of a vertebrate pest management plan needs to be on impacts of pest animals rather than on pest animal numbers. Such impacts may include • Agricultural – damage to crops, predation of livestock, pasture competition, land degradation, soil erosion, stream turbidity and the spread of weeds. • Environmental – competition for food and shelter, habitat destruction and predation. • Social – being a nuisance, damaging infrastructure or culturally important sites, causing traffic accidents and social and psychological effects on primary producers and their families. • Disease – vertebrate pest animals may act as reservoirs and spread mechanisms for diseases that affect native wildlife, livestock or people. N i l - tenure approach When developing regional or local vertebrate pest management plans consider a ‘nil tenure’ approach. This method involves the removal of all land tenure issues from the planning stage. This focuses on the problem, rather than on land ownership. Once the problem has been identified and the proposed control actions defined, the tenure boundaries can be reinstated and the resources and costs allocated proportionally or according to some agreed formula. One of the most successful examples of the use of a ‘nil tenure’ approach to pest animal management is the Brindabella and Wee Jasper Cooperative Wild Dog and Fox Program. G ro up cont rol program s Areas of pest animal abundance tend to be defined by topography, territoriality and food availability. Property fences do not restrict pests, and control strategies should not therefore be limited to artificial boundaries. Most pests are highly mobile and can readily replace those that are killed on individual properties. Unless actions are well planned and coordinated across a broader area of neighbouring properties, individual control programs are unlikely to have a lasting effect. Control programs are therefore likely to be far more effective when multiple landholdings are involved. Where possible work with already established groups such as Landcare, bushfire brigades, social groups including neighbouring public land managers. INTRODUC TION 11 The benefits of group control include better coordination and communication between all stakeholders. For example, during a pest control program everyone in the group knows who is baiting, where baits are laid, how much poisoned bait has been distributed, and when baits are to be picked up or destroyed. Where a pest may be difficult to control, the use of a group’s resources to help one land manager for the benefit of all justifies a coordinated approach. Peer pressure may be applied judiciously to facilitate control within an area if required. The success or failure of pest animal control groups is largely dependent on the enthusiasm and dedication of the group coordinator. The coordinator should have credibility, be well respected and able to draw on personal and or other people’s experiences. The coordinator should liaise closely with their local LLS Biosecurity Officer. I ntegrated Pes t M an ag ement Integrated pest management uses a combination of practices and control methods to manage pests. The use of an appropriate combination of control methods is likely to be more effective than a reliance on one or two methods alone. When conducting a rabbit control program for example it may be useful to employ poisoned baits in combination with harbour removal, warren destruction and the use of a biological control agent such as rabbit haemorrhagic disease virus (RHDV). Control methods that may be considered when developing a local management plan could include: • killing or removal by baiting, shooting, trapping or mustering • exclusion fencing or netting • biological or fertility control • habitat manipulation by removal of surface refuges and warren destruction • changes in timing of animal husbandry management such as lambing or planting different crops. Developing local or regio n al man ag ement p lan s Vertebrate pest management plans should provide a clear understanding of the pest problem in a region or local area, identify the impacts of pest animals, set clear and achievable goals and outline an implementation strategy for controlling pests. A number of useful publications and tools can be used to develop plans such as Braysher, M. 1993, Managing Vertebrate Pests: Principles and Strategies, Australian Government Printing Services, Canberra and Braysher, M and Saunders, G. 2003, PESTPLAN: A guide to setting priorities and developing a management plan for pest animals, Canberra. These documents are available at www.feral.org.au VERTEBRATE PEST CONTROL MANUAL 12 INTRODUC TION Whilst pest management plans will vary from region to region depending on local issues, available resources, prevalence and distribution of pest species and impacts on production and conservation values, a number of common planning and development principles should be applied. The following ten steps should be considered to develop a successful vertebrate pest management plan. Table 1: Ten Step process for developing a regional or local vertebrate pest management plan (Adapted from PESTPLAN: A guide to setting priorities and developing a management plan for pest animals.) STEP DESCRIPTION KEY CONSIDERATIONS Step 1. Define the problem •Concentrate the planning process on managing and reducing the impacts of pest species, rather than simply a focus on pest abundance and distribution alone. •Identify and if possible, quantify the production and /or conservation values under threat from pests. • Does the cost of pest control outweigh the benefits from control? Step 2. Identify and engage key stakeholders • Identify stakeholders who may be impacted by the management plan. •Discuss the pest animal problem with affected land managers and their neighbours to identify •Involving stakeholders early gives them ownership of the planning process and the scope of the problem, who has the problem, is likely to improve the level of cooperation and involvement. Stakeholders may where is the problem and how severe is it? be engaged as early as Step 1 of the process. Step 3. Identify and prioritise key land management areas •Managing pest animals over a large area, for example across an entire LLS area of operations, may be more easily achieved by dividing regions into smaller, more manageable areas of land (land management areas). Land management areas may be determined by land use, soil or vegetation types or target pest species. Land management areas may also be determined by social or political boundaries including catchment boundaries, Landcare groups, local council boundaries or specific LLS boundaries. •Land management areas should ideally have clearly marked boundaries to work to and mapped to facilitate the planning process. •Land management areas should be ranked or prioritised based on their production or land management values, conservation values and threat from pest animals. Step 4. Determine management goals and measurable objectives •Define the pest problem(s) in terms of the degree or extent of harmful impact •Monitor and evaluate the problem to establish on production and conservation values due to the pests. benchmarks and goals. •Set clear, measurable and time-limited objectives aimed at reducing the level •Objectives should identify when the problem has of pest animal damage to an acceptable level. For example an objective for been resolved and what information will be used feral pig damage to lamb production may be to increase lamb marking rates by to evaluate the outcome of the program. 20% after one year of feral pig control or to increase wattle regeneration by 5% after one year of feral goat control. • Set clear milestones and performance indicators. • Is the problem real or perceived? •Define the problem in terms that measure the impacts of the pest animals. •Prioritise areas and management options based on animal impacts. •Maps are an invaluable tool when developing strategic management plans. Step 5. Identify •The most appropriate management options will depend on a range of variables •Options for control should consider economic, and evaluate including level of impacts, pest species, available resources, community environmental, social, political and legal management options attitudes and involvement and political pressure. outcomes. and conduct a risk • Options for addressing pest animal damage include: •Determine the costs of control. Do these outweigh analysis the benefits? If so, what other approaches may be – Local eradication however this is rarely feasible or achievable considered? – Strategic management: One-off control Sustained management Targeted management No Control. •Pest animal managers should consider incorporating a comprehensive risk analysis for each of the options. A risk analysis will help to identify the costs and benefits of the various options, as well as the potential consequences and undesirable outcomes of implementing each of the control options. INTRODUC TION 13 Table 1 (continued): Ten Step process for developing a regional or local vertebrate pest management plan (Adapted from PESTPLAN: A guide to setting priorities and developing a management plan for pest animals.) STEP DESCRIPTION KEY CONSIDERATIONS Step 6. Develop a detailed management plan • A detailed management plan should clearly state the objectives of the plan. •The plan should define the actions that will be undertaken: who will do what, when, how and where. It describes how the selected pest management options and techniques will be integrated and implemented to achieve the management objectives. •The plan should also clearly identify milestones and key performance indicators which will be used to monitor and evaluate the plan. •Use the SMART acronym to evaluate your plan, is the plan: – Specific – Measurable – Achievable – Realistic – Timed? Step 7. Implement the management plan •Develop and maintain effective communication with stakeholders during the implementation of the management plan(s). •Provide regular reports and updates on progress against milestones and key performance indicators and encourage feedback and comments from stakeholders throughout the implementation phase. • Delegate tasks to stakeholders. • Use trained and accredited contractors. Step 8. Monitor and evaluate outcomes • Measure the performance of your plan against the original objectives. • Performance assessment consists of two components: – Operational monitoring: what was done, when and at what cost. – Performance monitoring: were the objectives of the plan achieved and if not why not? Were pest animal impacts reduced? If not, is this because other unforeseeable issues were having an impact on production or conservation values? •Share the results of your monitoring and evaluation with your stakeholders and seek their input. • Monitor before, during and after the program. •Monitor both pest animal numbers and impacts such as the number of lambs marked after the control program was implemented, increased plant regeneration. •Has the management strategy solved the problem through achieving the stated objectives? •Should the program be continued, be better resourced, altered or stopped? Step 9. Implement adaptive management: modify management plan and objectives as necessary based on monitoring and evaluation Adaptive management allows the knowledge and experience gained in implementing and monitoring the plan to be incorporated into future actions or to modify and amend the current plan depending on the outcomes being achieved. Plans should therefore be reviewed as often as practicable to determine if objectives are being met and if changes to the plan is required. •Pest animal management plans should be ‘living documents’ which are updated and amended in response to changes, outcomes and contingencies identified during the implementation of the plan. Step 10. Report and share outcomes After completion of the implementation, monitoring and evaluation phases of the •Reporting the outcomes of your pest animal plan it is critical that the results and outcomes of the plan be communicated to management plan will maintain the support and stakeholders and the broader community. This will ensure sustained cooperation cooperation of stakeholders. and support for future programs and initiatives. VERTEBRATE PEST CONTROL MANUAL 14 INTRODUC TION A number of options for managing pest animals may be considered when developing pest animal management plans. 1. Local Eradication Eradication is the permanent removal of the entire pest population. Eradication is rarely achievable even on a local scale, unless the following criteria can be met: 1. Pests can be killed at a faster rate than they can replace themselves. 2. Immigration must be zero. 3. All individuals of the population must be at risk from the control techniques used. 4. The species must be able to be monitored at very low densities. 5. The social-political environment supports eradication. 6. The costs of eradication can be justified. 2. Strategic Management a) One-off control Long term or permanent reduction of the impacts of some pests may be possible with one action or set of actions. Actions may include exclusion fencing or netting or creating an unsuitable habitat for the pest with a biological control agent. b)Sustained management Sustained control is when the pest animal density is reduced and then maintained at or near a threshold density at which there is no increase in benefit from additional control. This is usually achieved through an initial knockdown removing a high proportion of the population followed by periodic maintenance control to slow or prevent recovery. c) Targeted management Action is directed at the individual or group of individual animals causing most of the damage, or applied when damage is most critical such as targeting a small group of experienced feral pigs identified as the primary predators of young lambs rather than focusing on the overall density of feral pigs in the local area. 3. No control In certain instances no control may be an option at a particular point in time. F E R A L A N I M A L A E R I A L S H O OT I N G T E A M Feral Animal Aerial Shooting Team (FAAST) training is a system for accrediting LLS and NPWS employees to carry out aerial shooting of animals from helicopters. The FAAST policy requires all aerial culling programs to be conducted according to FAAST protocols by FAASTaccredited shooters. A FAAST management committee guides the training program, this committee consists of representatives from NSW DPI, NPWS, RSPCA and Local Land Services. FAAST training courses are held every 3 or 4 years or when the demand for more trained shooters necessitates a course. Students are required to complete a rigorous training program in the safe use of firearms, marksmanship, the humane destruction of animals, and helicopter safety. They are also required to complete a biannual reaccreditation to ensure marksmanship, firearm familiarisation and aircraft safety remains at a high standard. If a pest management program includes aerial shooting contact your local LLS or NPWS office to access the services of a FAAST accredited shooter. It should be noted that aerial shooting is also undertaken by private contractors in NSW, this is not the same as FAAST. INTRODUC TION 15 VERTEBRATE PEST CONTROL MANUAL 16 INTRODUC TION Legislation Legislation in NSW for vertebrate pest management and pesticide use will vary from legislation in other States and Territories. All agencies and officers from interstate jurisdictions, conducting pest animal management need to be aware of the relevant legislative requirements in their own State or Territory. Vertebrate pest control officers and ACOs from government departments work within a number of NSW and Commonwealth Acts, Regulations, Orders and other legislative instruments. It is most important that all officers, regardless of who they work for, know and understand their various legislative functions, obligations and powers. This ensures that vertebrate pests are controlled effectively, efficiently and humanely, that the rights of all land managers are protected, and that work health and safety hazards are identified, risk rated and managed. The purpose of this section is to provide a summary of the key legislation governing pest animal management in NSW, as well as other related legislation. It is not intended to replace or interpret the legislation and all officers are urged to read the full text of the relevant Acts, Regulations and Orders. The main legislation that needs to be considered for pest animal management and pesticide use in NSW includes but is not limited to: • Local Land Services Act 2013 • Pesticides Act 1999 and Regulation 2009 • Work Health and Safety Act 2011 and Regulation 2011 • Agricultural and Veterinary Chemicals Code Act 1994 (Commonwealth) • Prevention of Cruelty to Animals Act 1979 • Game and Feral Animal Control Act 2002 (amended 2014) • National Parks and Wildlife Act 1974 and Amendment 2001 • Threatened Species Conservation Act 1995 • Native Vegetation Act 2003 • Deer Act 2006 • Protection of the Environment Operations Act 1997 Complete copies of the legislation listed above are available at: www.legislation.nsw.gov.au, www.lawfoundation.net.au or www.austlii.edu.au LO C A L L A N D S E R V I C E S AC T 2013 The Local Land Services Act 2013 ( LLS Act) is the principal legislative instrument governing the management of vertebrate pests and plague locusts in NSW and is administered by Local Land Services. Under Part 10 of this Act, the Minister may make, through publication in the NSW Government Gazette, Pest Control Orders and declare any animals, birds or insects to be ‘pests’ and define ‘controlled land’ on which such pests are to be controlled. Currently rabbits, wild dogs, feral pigs and three species of locust (Australian plague locust, Migratory locust and the Spur-throated locust) are declared pests under the LLS ACT. LEGISLATION 17 The Minister may impose various ‘destruction’ and ‘notification’ obligations on occupiers of controlled land, including public land managers and local government authorities that require occupiers to ‘continually suppress and destroy declared pests’. The Minister may also empower authorities to serve individual and general eradication orders on any occupier or owner of controlled land in its district to eradicate pests by methods specified in the order. The LLS Act also contains provisions which may be used to confer significant powers on ‘authorised officers’ to carry out work on controlled land, and to confer powers on authorities in relation to the implementation and administration of Pest Control Orders. LLS may order the occupier or owner of any land to control declared pest species by using any legal method: applying a registered or permitted pesticide; fumigation; digging in or out; ploughing in or out; explosives; trapping; dogging; removal or destruction of harbour; ripping; and shooting, including aerial shooting. An authorised officer may examine, seize, detain or remove any pest from or about a premise. An authorised officer may remove or destroy or cause to be removed or destroyed any pest found in or about those premises that is being kept in captivity without lawful authority, such as feral pigs raised in urban backyards. In addition to declared pests, LLS may be involved in the control of foxes and mice to minimise their impacts on agriculture and the environment. The Minister must consult the NSW Pest Animal Council and the Game and Pest Management Advisory Board before declaring an animal that is already declared a game animal under the Game and Feral Animal Control Act 2002 (amended 2014) to be a pest animal under the LLS Act. The relevant sections of the LLS Act are summarised below. This summary is not intended to replace or interpret the LLS Act; it is intended only to give a broad overview of the duties and responsibilities of LLS as well as public and private land managers. Table 2: Summary of relevant sections of the LLS Act with regards to pest control Local Land Services Act 2013 Part 10 – Pests This part of the Act provides for the control of public and private land in NSW of animals, birds, insects and other members of the animal kingdom that are pests. DIVISION 2 – PEST CONTROL ORDER VERTEBRATE PEST CONTROL MANUAL 18 SECTION WHAT IT DOES Section 130 Minister may make pest control orders The Minister may, through Pest Control Orders published in the NSW Government Gazette, declare animals, birds or insects to be ‘pests’ and define ‘controlled land’ on which such pests are to be controlled. Presently, wild rabbits, wild dogs, feral pigs and three species of locust are declared pests under the Act. Pest Control Orders are made for the purpose of controlling of pest animals on designated public or private land that are adversely impacting on agricultural enterprises or natural and urban environments. Pest Control Orders may direct that particular control methods are used. Local Land Services may issue a control order to the occupier or owner of any land to control declared pest animals, on that land, by use of any lawful method. In effect, under the above provisions there are three different types of obligations or orders. They are: (a)A general destruction obligation. This is an on-going obligation on occupiers of land to ‘eradicate’ declared noxious vertebrate pests on land throughout the State. It is issued by the Minister. (b)An individual eradication order that may be issued by a LLS. Such an order is issued to the occupier of an individual holding if he/she has failed to comply with the on-going obligation referred to above. (c)A general eradication order that may be issued by a LLS in relation to all or part of its district. This type of order may be issued by a LLS if land managers generally within the district (or part of the district) have failed to comply with the general destruction obligation. LEGISLATION Sections 142 and 143 Obligations of owners and occupiers of private and public land Occupiers of private and public land to which a control order applies must implement any control measures specified in that order. Occupiers of private and public land must notify authorities of the presence of pests which are subject to notification obligations as soon as practicable after becoming aware of their presence such as plague locusts. Alternative methods (to those specified in pest control orders) of pest eradication may be approved by Local Land Services. DIVISION 3 – ERADICATION ORDERS SECTION WHAT IT DOES Sections 144 and 145 When are eradication orders issued and what is the period of compliance Local Land Services may give an eradication order in relation to a pest on controlled land only if Local Land Services considers that it is necessary to give it to ensure the effective eradication of the pest on the land. An individual eradication order is to be served on the occupier or owner of the land concerned. A general eradication order is to be published in a newspaper circulating generally in the region or part of the region concerned. Eradication orders must specify a reasonable period within which the terms of the order are to be complied with unless, circumstances prevail in which serious risk of harm is being caused by pests. DIVISION 4 – POWERS OF AUTHORISED OFFICERS AND OTHERS CONCERNING ERADICATION OF PESTS SECTION WHAT IT DOES Section 151 Eradication of pests An authorised officer may take such measures and carry out such work on any controlled land as the authorised officer considers necessary to eradicate pests on the land if: (a) a pest control order authorises the taking of such action, or (b)the owner or occupier of the land has failed to comply with a pest control order or an eradication order applying to the land, or (c) the owner or occupier of the land consents to the measures or work being taken or carried out. Section 152 Destruction of pests may be required Authorised officers may require persons in possession of a pest to destroy the pest or to move the pest to a place where it is not a pest. If a person fails to comply with the above notice an authorised officer may take the required action. Authorised officers who on reasonable grounds believe a vehicle may contain a pest may require the driver to stop the vehicle, may search the vehicle, may require the driver to move a vehicle to a place at which a pest can be destroyed and may seize and destroy a pest found in or on a vehicle. Section 153 Compliance notice pests Authorities may impose inspection charges and charges to cover the reasonable expenses of any action taken as a consequence of owners or occupiers failing to control pests on their land. DIVISION 5 – MISCELLANEOUS SECTION WHAT IT DOES Section 156 Approval to keep a pest in captivity or use alternative method of eradication (1)If Local Land Services is empowered by a pest control order to give approval to keep a pest in captivity, any person may apply in writing to Local Land Services for approval for the person to keep the pest in captivity on specified land. (2)If Local Land Services is empowered by a pest control order to give approval for use of an alternative method of eradication of a pest, any person may apply in writing to Local Land Services for approval to use an alternative method of eradication described in the application to that specified in the order. (3)Local Land Services may give the approval sought in writing subject to the conditions (if any) stated in the approval. (4)An application under this section is taken (for the purposes only of any appeal) to have been refused if it has not been determined within the period of 40 days after the making of the application. Section 158 Offences relating to pests in captivity (1)A person must not keep a pest in captivity on any land except in accordance with an approval to keep the pest in captivity on the land given under section 156. (2)Any person who (without lawful excuse) liberates, or attempts to liberate, a pest from captivity is guilty of an offence. LEGISLATION 19 Section 160 (1)A person must not, without lawful excuse, carry, drive or pass a pest through, under or over a fence or gate on any land (whether controlled land or otherwise) that is designed to prevent such a pest from entering land. Offences involving fences and pests and conveyance of pests (2) A person must not, without lawful excuse: (a)leave open a gate in a fence on any land (whether controlled land or otherwise) that is designed to prevent pests from entering land, or (b) destroy or damage any such fence or gate, or (c)interfere with any such fence or gate or the surface or subsurface under it in a manner likely to impair its effectiveness as a barrier to such pests. (3)A person must not, without lawful excuse, convey a live pest from one place to another (whether by vehicle or otherwise). Section 161 Damage, destruction, removal of eradication devices A person must not, without lawful excuse: (a)destroy, damage or remove any thing that is being used or intended to be used for the purposes of eradicating pests in accordance with this Part, or (b) interfere with any such thing in a manner that is likely to impair its effectiveness. Part 11 – Powers of authorised officers This part of the LLS Act details what powers an authorised officer has regarding entry to property and undertaking control works DIVISION 1 – PRELIMINARY SECTION WHAT IT DOES Sections 164 Power of entry and Purposes (1) An authorised officer may enter any premises to enable the authorised officer to exercise any function conferred or imposed on the authorised officer, or any function of Local Land Services that the officer is authorised to exercise, by or under this Act. (2) The authorised officer may enter premises with such persons and with such vehicles, horses and dogs as the authorised officer considers are necessary to enable or assist the authorised officer to exercise the function concerned. 165 Purposes for which powers under Part may be exercised Powers may be exercised under this Part for the following purposes: (a) for determining whether there has been compliance with or a contravention of this Act or the regulations or any order, licence, notice, permit or requirement issued or made under this Act, (b) for obtaining information or records for purposes connected with the administration of this Act, (c) for the purpose of enabling Local Land Services, the authorised officer or any other person to exercise any function conferred or imposed on the person under this or any other Act. DIVISION 2 – AUTHORISED OFFICERS SECTION WHAT IT DOES Section 171 Entry into residential premises only with permission or warrant An authorised officer may only enter residential premises with the permission of the occupier or with a search warrant issued under Section 178. Section 172 Powers of authorised officers to do things on premises Authorised officers may do anything that in the opinion of the authorised officer is necessary to be done for the purposes of this Act. Subsection (2) includes (but is not limited to) a range of the things authorised officers may do. Section 173 Notice of entry (1)and (2) Notice of entry must be given at least one day prior to entry and may be oral or written. (3) This section does not require notice to be given: (a) if entry to the premises is made with the consent of the occupier of the premises, or (b) if entry has been authorised by a search warrant issued under section 196, or (c)if entry is required urgently and the authorising authority has authorised in writing (either generally or in the particular case) entry without notice, or (c1)if the authorised officer concerned is a police officer and the giving of notice would defeat the purpose for which it is intended to exercise the power of entry, or (d) if entry is required to eradicate any pest kept in captivity without lawful authority. VERTEBRATE PEST CONTROL MANUAL 20 LEGISLATION Part 14 – Miscellaneous SECTION WHAT IT DOES Section 209 Service of documents (1) A document may be served on Local Land Services by leaving it at, or by sending it by post to: (a) the office of Local Land Services, or (b) if it has more than one office—any one of its offices. (2)A document that is authorised or required by this Act or the regulations to be served on any other person may be served by: (a) in the case of a natural person: (i) delivering it to the person personally, or (ii)sending it by post to the address specified by the person for the giving or service of documents or, if no such address is specified, the residential or business address of the person last known to the person giving or serving the document, or (iii) sending it by facsimile transmission to the facsimile number of the person, or (b) in the case of a body corporate: (i)leaving it with a person apparently of or above the age of 16 years at, or by sending it by post to, the head office, a registered office or a principal office of the body corporate or to an address specified by the body corporate for the giving or service of documents, or (ii) sending it by facsimile transmission to the facsimile number of the body corporate. (3)Nothing in this section affects the operation of any provision of a law or of the rules of a court authorising a document to be served on a person in any other manner. PART 13 – MISCELLANEOUS SECTION WHAT IT DOES 100 Nuisance animals An authority at the request of the owner or occupier of a holding in its district, may carry out any activity it considers necessary to control any animal (other than a pest within the meaning of Part 10 of the Act) causing a nuisance on the holding. P E S T I C I D E S AC T 1999 The Pesticides Act 1999 (Pesticides Act) is the primary legislative instrument controlling the use of pesticides in NSW and is administered by the EPA. The underlying principle of the Act is that pesticides must only be used for the purpose described on the product label or permit and all the instructions on the label or permit must be followed. Consequently, all label or permit directions must be read by or explained to the user prior to each use of the pesticide. The relevant sections of the Pesticides Act and Regulation 2009 are summarised below. This summary is not intended to replace or interpret the Pesticides Act and Regulation 2009. It is intended only to give a broad overview of the duties and responsibilities of ACOs as well as public and private land managers. LEGISLATION 21 Table 3: Summary of relevant sections of the Pesticides Act with regards to pest control. Pesticides Act 1999 This Act aims to protect and reduce the risk associated with the use of pesticides to human health, the environment, property, industry and trade and to promote collaborative and integrated policies and establish a legislative framework to regulate the use of pesticides PART 1 – PRELIMINARY Section 4 – Definitions Harm an animal or plant includes poison, injure, contaminate, infect, distress, maim, impair or kill the animal or plant. Injury to a person includes any kind of physical or psychological injury whether temporary or permanent, including conditions such as nausea, allergic reaction, dizziness, headache, stress, and running nose or eyes. Section 5 – Meaning of ‘pesticide’ (1)A pesticide means: • an agricultural chemical product within the meaning of the Agvet Code, or •a veterinary chemical product (within the meaning of the Agvet Code) that is represented as being suitable for, or is manufactured, supplied or used for, the external control of ectoparasites of animals. Note: The Agvet Code defines an ‘agricultural chemical product’ to be a substance or a mixture of substances that is represented, imported, manufactured, supplied or used as a means of directly or indirectly: (a) destroying, stupefying, repelling, inhibiting the feeding of, or preventing infestation by or attacks of, any pest in relation to a plant, a place or a thing, or (b) destroying a plant, or (c) modifying the physiology of a plant or pest so as to alter its natural development, productivity, quality or reproductive capacity, or (d) modifying an effect of another agricultural chemical product, or (e) attracting a pest for the purpose of destroying it. The term also includes insect repellants for use on human beings. (2) A pesticide continues to be regarded as a pesticide even when it is mixed with some other substance (whether or not the other substance is a pesticide). However, a pesticide does not include a prescribed mixture or a mixture of a prescribed class or description. Note: Subsection (2) generally deals with the situation where a pesticide is diluted, or is mixed, before being used. The effect of the provision is that the mixing of a pesticide does not mean that it is no longer a pesticide. PENALTIES SUMMARISED The Pesticides Act 1999 contains penalties of up to $250,000 in the case of a corporation, or $120,000 in the case of an individual for various offences under each Section. Some Sections provide defenses against prosecution such as: ‘On-farm’ exception where a person does not commit an offence if the person establishes: (a) that the injury or damage occurred, or is likely to occur, only on the agricultural farm land in respect of which the pesticide was used, and (b) that the person is the occupier of that land or is employed or engaged by the occupier of that land. ‘On-farm’/residential premises exception where a person does not commit an offence if the person establishes: (a) that the harm occurred only on the agricultural farm land, or the residential premises, in respect of which the pesticide was used, and (b) that the person is the occupier of that land or those premises, or is employed or engaged by the occupier of that land or those premises. Some Sections have a ‘Due diligence’ defence where it is a defence in any proceedings against a person for an offence under this section if the person establishes: (a) that the commission of the offence was due to causes over which the person had no control, and (b) that the person took all reasonable precautions and exercised all due diligence to prevent the commission of the offence. While other Sections state it is a defence in any proceedings against a person for an offence if the person establishes that (a) the person complied with the relevant instructions on an approved label that was, at the time of the alleged offence, affixed or attached to, or appeared on, the container for the pesticide that was used, (b) (i)the person used the pesticide at a concentration or rate lower than that specified in the instructions on an approved label provided such lower concentration or rate was not prohibited by the instructions or by any pesticide control order (ii) otherwise complied with the relevant instructions on the approved label. VERTEBRATE PEST CONTROL MANUAL 22 LEGISLATION PART 2 – CONTROL OF PESTICIDES DIVISION 1 – WILFUL OR NEGLIGENT MISUSE OF PESTICIDES SECTION WHAT IT DOES Section 7 (1) A person is guilty of an offence if the person wilfully or negligently uses a pesticide in a manner that: Injury to persons or damage to property (a) injures or is likely to injure any other person, or resulting from pesticide use (b) damages or is likely to damage any property of another person. An ‘On-farm’ exception applies to subsection (1). Section 8 Harm to animals or plants resulting from pesticide use (1) A person is guilty of an offence if the person wilfully or negligently uses a pesticide in a manner that: (a) harms any non-target animal or non-target plant, or (b) if there is no approved label or permit for the pesticide – harms any animal or plant. An ‘On-farm’/residential premises exception applies to subsection (1) Section 9 Material harm to endangered , vulnerable or protected species (1)A person is guilty of an offence if the person wilfully or negligently uses a pesticide in a manner that materially harms: (a)an animal that is a threatened species within the meaning of the Threatened Species Conservation Act 1995, or (b) any protected fauna within the meaning of the National Parks and Wildlife Act 1974. (2) When considering material harm the following matters are taken into consideration: (a) the number of animals harmed, (b) the type of animals harmed, (c) the local population of the type of animal harmed. DIVISION 2 – MISUSE OF PESTICIDES SECTION WHAT IT DOES Section 10 (1) A person must not use a pesticide in a manner that: Injury to persons or damage to property (a) injures or is likely to injure any other person, or resulting from pesticide use (b) damages or is likely to damage any property of another person Section 11 Harm to animals or plants resulting from pesticide use (1) A person must not use a pesticide in a manner that: (a) harms any non-target animal or non-target plant, or (b) if there is no approved label or permit for the pesticide – harms any animal or plant. DIVISION 3 – GENERAL OFFENCES RELATING TO THE CONTROL OF PESTICIDES SECTION WHAT IT DOES Section 12 Possession of unregistered pesticide Section 13 Use of unregistered pesticide A person must not possess or use an unregistered pesticide unless the person: (a) is authorised to do so by a permit, and (b) complies with the permit. Section 14 Requirement to read approved label and permit (1) A person must on each occasion before using a registered pesticide (a) read an approved label for the pesticide or (b) ensure that an approved label for the pesticide is explained to the person (2)If a permit is in force in respect of a pesticide, a person to whom the permit applies must on each occasion, before using the pesticide: (a) read the permit, or (b) ensure that the permit is explained to the person. (3)If a pesticide is mixed with any other substance, the approved label or permit for that pesticide still must be read. LEGISLATION 23 Section 15 Using pesticide contrary to approved label (1)A person must not use a registered pesticide in contravention of any instruction on an approved label for the pesticide unless the person: (a) is authorised to do so by a permit, and (b) complies with the permit (2)If a registered pesticide is mixed with any other substance, the requirement under subsection (1) in relation to the pesticide is not affected. Note. The mixing of a registered pesticide with another substance still means that the relevant instructions on the approved label for the pesticide must be followed. An exception is to use a concentration or rate lower than that specified in the instructions on an approved label provided any such lower concentration or rate was not prohibited by the instructions or by any pesticide control order. Section 16 (1)A person must not, without reasonable excuse, keep a registered pesticide in a container that does not have an approved label attached to the container. Keeping pesticides in container without approved label Section 17 Use or possession of restricted pesticides (1) A person must not possess or use a restricted pesticide unless authorised to do so by: (a) a certificate of competency, or (b) a pesticide control order. PART 4 – PESTICIDE CONTROL ORDERS SECTION WHAT IT DOES Section 38 Making of pesticide control order Section 39 Operation of pesticide control order The Office of Environment & Heritage may, with the approval of the Minister, make a pesticide control order (PCO). The PCO may put in place additional restrictions on the possession or use of pesticides on a state wide basis. For vertebrate pest poisons this includes the restricted pesticides of 1080 and pindone. PART 6 – LICENCES AND CERTIFICATES OF COMPETENCY DIVISION 1 LICENSING OF AERIAL PESTICIDE OPERATORS SECTION WHAT IT DOES Sections 45 to 55 These sections detail the requirements for licensing, record keeping and suspension or revocation of licence for aerial pesticide operators. PART 10 – PROCEDURAL PROVISIONS DIVISION 6 – OTHER PROCEDURAL PROVISIONS SECTION WHAT IT DOES Section 111 Causing or permitting offence A person who causes or permits, by act or omission, another person to commit an offence under a provision of this Act or the regulations is guilty of an offence under that provision and is also liable. PART 11 – MISCELLANEOUS SECTION WHAT IT DOES Section 119 Regulations This section states the regulation can detail such directions as the requirements for record keeping, notification of use, accreditation and compulsory training of pesticide users. Note: ‘Wilful or negligent misuse’ of pesticides is distinguished from ‘misuse of pesticides’ in the Pesticides Act. There are higher penalties for people who wilfully or negligently misuse pesticides causing injury, damage or harm. All pesticide users should take reasonable care to protect their own health and the health of others when using a pesticide. They should also make every reasonable attempt to prevent damage occurring from the use of a pesticide, such as off-target drift onto sensitive areas or harm to endangered and protected species. VERTEBRATE PEST CONTROL MANUAL 24 LEGISLATION Pe s t icide Cont rol O rder s When the Australian Pesticide and Veterinary Medicines Authority (APVMA) declares pesticides products to be RCPs, they can only be supplied to and used by authorised persons under the Pesticides Act The Pesticides Act requires a person who uses a RCP to be authorised to do so by way of PCOs. PCOs specify controls over pesticide use, the preparation of bait and the use of each vertebrate pesticide. Each PCO is published in the NSW Government Gazette and commences on the date specified in the order. An advertisement is also placed in certain newspapers so that the public are made aware that EPA has made these orders. Currently, sodium fluoroacetate (1080), pindone, and RHDV are all classified as RCPs and must be used in accordance with the directions of a PCO. ACOs should ensure that they always have current PCOs for the RCPs they issue to land managers. ACOs are also required to provide land managers with a copy of the PCO for each RCP they issue to land managers. PCOs can be downloaded from the EPA website at www.epa.nsw.gov.au/pesticides/pco.htm P E S T I C I D E S R E G U L AT I O N 200 9 The Pesticide Regulation 2009 (the Regulation) specifies the need to keep records, for commercial users to be trained and for public authorities and others to notify when they are intending to apply pesticides to public land to which the public has access. Note: The Regulation does not apply to those who use pesticides for domestic or garden purposes. R e co rds Records must be made within 24 hours of application, be made in legible English, and kept for 3 years. If a contractor, LLS or other authority applies pesticides to a person’s property, then they must provide a copy of the record of pesticide application to that person. While no set form has to be used, records must include the following: • the full product name of the pesticide bait used, such as 1080 Poisoned Bait in chicken wingettes • description of the situation in which you used the pesticide, such as rabbit control in pasture • the rate of application and the quantity of pesticide bait applied e.g.10 kg ‘Mouseoff Zinc Phosphide Bait’ over 10 hectares • a description of the equipment used such as bait layer, using cut furrow-trailing method • the property address and a delineation of the area where the pesticide baits were laid, such as, 2 km trail of bait laid in paddock D, a sketch of the area may be useful • the date and time of the application including start and finish times and the date baits were retrieved • the name, address and contact details of the person who applied the pesticide LEGISLATION 25 • the name, address and contact details of the owner or the person who has the management or control of the land • weather conditions specified as relevant on the label. A factsheet on Pesticide Record Keeping Vertebrate Pest Baiting is available at www.epa.nsw.gov.au/resources/pesticides/baiting.pdf The vertebrate pesticide usage and supply record (such as the Financial and Rural Management System (FARMS)) is an inventory of vertebrate pesticide use by the LLS or other authorised agencies. While it shows details of type of baits, who was issued with baits and the property where baits were destined, it is not a record of pesticide use. That must be made by the end user, the land manager, employee or contractor placing the baits, including LLS, NPWS or other government agency staff who lay baits on public or private land. Aer ial applicat ion of baits Different record keeping rules apply to situations where baits are distributed from an aircraft. Baits can only be applied from an aircraft if the pilot has a pesticide or agricultural rating and the aircraft has an air operator’s certificate endorsed for pesticide application or is employed or engaged by the holder of an aircraft (pesticide applicator) licence. Bait droppers need to have at least Australian Qualifications Framework Level 3 (AQF3) Chemical use accreditation. A pesticide application record applicable to the bait line must be completed by the aerial contractor and supplied to the land manager. Contact EPA if further information on record keeping rules for aerial pesticide applications is required. Us er t raining All pesticide users must complete the prescribed training qualifications in pesticide use and renew this training every five years by completing a refresher course. This includes anyone who uses any type of pesticides, including herbicides, insecticides, fungicides, bactericides, baits, lures and rodenticides (rat poison) in their work. Only domestic use, such as home gardens, is excluded, provided the pesticide is a specific domestic or home garden product. If a person is working as a pest management technician, or who conducts fumigation or as an aerial applicator under the Pesticides Act these training requirements do not apply. There are separate training requirements necessary for this type of work. The minimum prescribed competency level of accreditation for chemical use is Australian Qualifications Framework level 2 (AQF2). Owner-applicators and pest control personnel are required to be accredited at AQF3 level. ACO’s who issue 1080 and pindone have the added responsibility of supplying and instructing land managers on the safe and effective use of these pesticides and thus must have chemical use accreditation at AQF4 level. Land managers who only use pre-prepared or manufactured baits of 1080 and pindone pre-prepared products to control vertebrate pests, and who use no other pesticides, may complete the EPA gazetted short course run by LLS or a Registered Training Organisation to satisfy the minimum training requirements for pesticide use. VERTEBRATE PEST CONTROL MANUAL 26 LEGISLATION N o t i f icat ion The Regulation requires the development of a Pesticide Use Notification Plan (PUNP) for public spaces where pesticides are applied and to which the public has access. Public spaces requiring a PUNP may include gardens, picnic areas, playgrounds, parks, sporting fields, road verges, electricity or rail easements legally accessible by the public, national parks, state forest, and crown land. Water bodies on public lands must be included in a PUNP if aquatic weeds are to be sprayed or if pest fish are to be controlled by application of pesticides to water. The plan has to define the means by which the community will be notified, such as on-site signs, letters to affected community members, and news items in the local paper or on the local radio. The PUNP should set out what information will be provided to the community. This should include, the product name of pesticide applied, the purpose for which the pesticide was applied such as fox control, the place, the date, applicator contact details (phone number and/or internet address) and re-entry period. AG R I C U LT U R A L A N D V E T E R I N A RY C H E M I C A L S CO D E AC T 1994 The registration of agricultural and veterinary chemicals and their products is conducted through a national registration scheme. All aspects of Agvet chemicals up until the point of retail sale is controlled by the federal Agricultural and Veterinary Chemicals Code Act 1994 (AgVet Code 1994). The AgVet Code 1994 is administered by the APVMA. State and territory legislation deals with all aspects of Agvet chemicals following the point of sale such as the control of chemical usage. For example, the APVMA regulates 1080 up to and including the point of retail sale. Once supplied to the end user, it comes under the regulation of individual States or Territories. NSW administers 1080 through a PCO issued under the Pesticides Act. Under the AgVet Code 1994, all pesticides possessed, sold, supplied or intended for use must be registered. It is an offence to possess or use an unregistered pesticide unless approval has been granted through an APVMA permit. Labels are registered under the AgVet Code 1994. It is illegal to detach, alter, deface, obliterate or destroy the label on a pesticide container or to affix other labels. The APVMA may declare certain chemical products to be RCPs if special training, and other requirements, are needed to be able to handle or use the chemical. Products that are declared to be RCPs can only be used by an authorised person. The relevant Australian State or Territory authority, such as EPA in NSW, determines who may be considered as an authorised person. Legislation relating to RCPs may be found in Part 4, Division 4 of the AgVet Code 1994. Currently RCPs that are vertebrate pest poisons include 1080, pindone and RHDV. LEGISLATION 27 Work Health and Safety Act 2011 As a result of a national review of work health and safety laws across the country, a model Work Health and Safety Act was developed and endorsed by the Workplace Relations Ministers’ Council in December 2009. Harmonisation in NSW has been achieved through the enactment of the Work Health and Safety Act 2011 (WHS Act). Essentially this means there is a national approach to State laws, and not a Commonwealth Act to replace State laws. Compliance with the WHS Act is enforced by WorkCover NSW. The main object of the WHS Act is to provide for a balanced and nationally consistent framework to secure the health and safety of workers and workplaces by: (a) protecting workers and other persons against harm to their health, safety and welfare through the elimination or minimisation of risks arising from work or from specified types of substances or plant, and (b) providing for fair and effective workplace representation, consultation, co-operation and issue resolution in relation to work health and safety, and (c) encouraging unions and employer organisations to take a constructive role in promoting improvements in work health and safety practices, and assisting persons conducting businesses or undertakings and workers to achieve a healthier and safer working environment, and (d) promoting the provision of advice, information, education and training in relation to work health and safety, and (e) securing compliance with this Act through effective and appropriate compliance and enforcement measures, and (f ) ensuring appropriate scrutiny and review of actions taken by persons exercising powers and performing functions under this Act, and (g) providing a framework for continuous improvement and progressively higher standards of work health and safety, and (h) maintaining and strengthening the national harmonisation of laws relating to work health and safety and to facilitate a consistent national approach to work health and safety in this jurisdiction. Relevant chapters in the Work Health and Safety Regulation will need to be reviewed including and not limited to topics such as Chapter 3 General risk and workplace management, Chapter 4 Hazardous work and Chapter 7 Hazardous chemicals. Relevant codes of practice should also be reviewed to provide guidance to eliminate or control risks in vertebrate pest management. Workers must also be aware of the following items: Schedule 7 Safety data sheets, Schedule 9 Classification, packaging and labelling requirements, Schedule 11 Placard and manifest quantities, Schedule 12 Manifest requirements, Schedule 13 Placard requirements, Schedule 14 Requirements for health monitoring and Clause 60 Exemptions and Clause 65 Pesticide operators and fumigators under Schedule 18B Savings and transitional provisions of WHS Regulation 2011. VERTEBRATE PEST CONTROL MANUAL 28 LEGISLATION Agri cult ural fum igant us e The occupational use of fumigants in NSW has required a fumigation certificate of competency under OHS legislation. LLS are exempt from requiring a fumigation certificate of competency for the manual application of aluminium phosphide and application of chloropricrin by pressure fumigator. Regulation of fumigants is not included in the new Workplace Health and Safety Act and Regulation 2011, which came into force on January 1, 2012. However, Transitional and Savings Arrangements made under Schedule 18 B will continue to be in force until other alternate arrangements have been made. Which means that the original exemption for LLS applies until Part 9.1 of the OHS Regulation is repealed. P R E V E N T I O N O F C RU E LT Y TO A N I M A L AC T 1979 The Prevention of Cruelty to Animals Act 1979 (Prevention of Cruelty to Animals Act) and its associated regulation legislate acceptable standards for animal welfare. The objectives of the Act, as described in Section 3, are: (a) to prevent cruelty to animals; and (b) to promote the welfare of animals by requiring a person in charge of an animal: (i) to provide care for the animal, and (ii) to treat the animal in a humane manner, and (iii) to ensure the welfare of the animal. The relevant sections of the Prevention of Cruelty to Animals Act are summarised below. This summary is not intended to replace or interpret the Prevention of Cruelty to Animals Act. It is intended only to give a broad overview of the areas of the Act that relate to vertebrate pests. Table 4: Summary of relevant sections of the Prevention to Cruelty of Animals Act with regards to pest control.

Prevention of Cruelty to Animals Act (General) Regulation 2006 PART 2 – PROVISIONS RELATING TO CONFINEMENT, CARRIAGE AND USE OF ANIMALS SECTION WHAT IT DOES Section 14 Prescribed parts of NSW and prescribed traps (1) For the purposes of Section 23 (1) of the Act, the prescribed parts of New South Wales are as follows: (a) the Eastern and Central Division within the meaning of the Crown Lands Act 1989, (b) the Western Division within the meaning of the Crown Lands Act 1989, (c) Lord Howe Island. (2) For the purposes of section 23 (1) of the Act, the prescribed types of trap are the following: (a) traps that are sold under any of the following trade or proprietary names or descriptions: (i) ‘Lane’s ‘Ace Rabbit Trap’, (ii) ‘Lane’s Dog Trap’, (iii) ‘Lane’s Round Jaw Wild Dog Trap’, (iv) ‘Lane’s Dingo Trap’, (v) ‘Oneida No 14 Steel Trap’, (b)any other trap that is similar in design, construction or manner of operation to any of the traps referred to in paragraph (a) (except for a soft-jawed trap, that is, a trap with steel jaws that are offset and padded). For the purposes of the Prevention of Cruelty to Animals Act, ‘animal’ includes vertebrate pests. The overriding concern for vertebrate pest managers under this Prevention of Cruelty to Animals Act is that risk assessments and due diligence should include provision to avoid unnecessary suffering of vertebrate pest animals during control activities. Exe m pt ions There are a number of practices that are exempt from the Prevention of Cruelty to Animals Act. Exempt activities include hunting, shooting, snaring, trapping, catching or capturing the animal, where the activity is undertaken ‘in a manner that inflicted no unnecessary pain on the animal’. Us e of cer t ain t ypes of t raps The Prevention of Cruelty to Animals Act prohibits the use or setting of steel-jawed traps in any part of NSW. Steel-jawed traps are defined as any trap that has jaws that are made of steel, iron or other metal and that are designed to spring together and trap an animal when a leg or other part of the animal’s body comes into contact with, or is placed between, the jaws. However, soft-jawed traps, that is, traps with steel jaws that are offset and padded are permitted to be used, see Part 2, Section 23 of the Prevention of Cruelty to Animals Act. LEGISLATION 31 Us e of dogs for pes t an imal co ntro l Dogs and other animals may be used when hunting, but only if their use is not in contravention to the Prevention of Cruelty to Animals Act; and their use is with the permission of the occupier of the land concerned. All dogs being used to hunt must be microchipped and wear a collar which has a metal tag or label attached with the name, address and telephone number of the owner of the dog. They must not chase any other species of animal not being hunted. When using dogs to hunt pigs on public land a person hunting alone may use up to three dogs and a group of hunters may use up to five dogs. Dogs must not be allowed to maul or kill pigs and hunters must take all necessary steps to ensure that their dogs do not inflict unnecessary pain on the pig. When using dogs to hunt deer a person hunting alone may use one dog to hunt deer or a group may use up to two dogs to hunt deer. The dogs must only be used to locate, point or flush the deer, the dog must not chase the deer or any other species. If not on a lead the dog must be wearing a radio tracking collar. Dogs must not be abandoned on public land. G A M E A N D F E R A L A N I M A L CO N T R O L AC T 2002 ( A M E N D E D 20 1 4 ) Game and feral animal hunting in NSW is subject to regulations to ensure the safety of all users of public land. The conditions which apply to legal hunting in NSW are set out in the Game and Feral Animal Act 2002 (amended 2014) (Game and Feral Animal Control Act) and associated Regulation. The NSW Department of Primary Industries, Game Licensing Unit is responsible for enforcement of and compliance with these conditions. Breaches of the regulations may result in serious penalties. Additional requirements apply depending on whether you are hunting on public land or hunting on private land. The objectives of the Game and Feral Animal Control Act are: (a) to provide for the effective management of introduced species of game animals, and (b) to promote responsible and orderly hunting of those game animals on public and private land and of certain pest animals on public land. The relevant sections of the Game and Feral Animal Control Act are summarised below. This summary is not intended to replace or interpret the Game and Feral Animal Control Act. It is intended only to give a broad overview of the areas of the Act that relate to vertebrate pests and their management.

LEGISLATION 35 N AT I O N A L PA R K S A N D W I L D L I F E AC T 1974 All native birds, reptiles, amphibians and mammals, except the dingo are protected in NSW under the National Parks and Wildlife Act 1979 (NPW Act) and the National Parks and Wildlife Regulations 2002. Once a particular plant or animal is listed as a threatened, vulnerable or endangered species they are afforded additional protection under the Threatened Species Act 1995. The agency responsible for the protection of native animals and plants in NSW is NPWS. Some native birds are not protected in certain parts of NSW because they are either agricultural or pastoral pests: • Sulphur-crested cockatoos and galahs have been declared ‘locally unprotected’ west of the Great Dividing Range in the Central and Western divisions of the state, because of the damage they do to grain crops • Crows and ravens (Corvids) are protected in the counties of Camden (Illawarra region), Cumberland (Sydney basin) and Northumberland (Hunter region) • The purple swamphen is not protected in 10 irrigation districts and areas in the Riverina region, where the species causes considerable damage to irrigated crops such as rice. The dingo is regarded as a wild dog under the LLS Act. Wild dogs are declared ‘pest animals’ under that legislation.

H ow are nat ive anim als pro tec ted ? The NPW Act contains a range of offences protecting native animals, and also a broad range of defences or lawful justifications: • It is an offence to harm protected fauna. This includes harm by using a substance such as poison, an animal such as hunting dog, a gun, net or trap. • It is an offence to buy, sell or possess protected fauna although sometimes licences are available to do this. • A person who is rescuing an injured animal will not commit an offence so long as they notify the Director-General in writing within 7 days that they have the animal. They are not allowed to keep the animal as a pet. • A person shall not liberate, anywhere in NSW, any animal, other than a homing pigeon or a captured animal that is native to NSW, unless under and in accordance with a licence under Section 127 of the Act. D e fe nces t hat per m it harm to n ative an imals A person will not have committed an offence if: • they had a licence • the work causing the harm was authorised under the Environmental Planning and Assessment Act 1979 such as done in accordance with a development consent under Part 4, a Part 5 approval or a Part 3A approval • they had a Conservation agreement or joint management agreement LEGISLATION 37 • they were returning the animal after escape • they were carrying out an activity permitted under the Native Vegetation Act 2003, such as clearing non-protected regrowth, continuing an existing farming activity or engaging in sustainable grazing, or • they were carrying out a routine agricultural activity. ‘Routine agricultural management activities’ include things such as: • constructing dams, fences, stockyards and farm roads • removing noxious weeds • controlling declared pest animals • collecting firewood, but not for commercial purposes • lopping native vegetation for stock fodder, and • traditional Aboriginal cultural activities, but not commercial activities. T H R E AT E N E D S P E C I E S CO N S E R VAT I O N AC T 1995 The Threatened Species Conservation Act 1995 (TSC Act) deals with threatened and endangered species in NSW. Schedule 1 lists the endangered species, populations and ecological communities. Schedule 2 lists the vulnerable species. Schedule 3 lists key threatening processes, which are identified as having significant impacts on the conservation of flora and fauna such as predation by the red fox and habitat degradation by feral goats. The term ‘threatened species’ includes both ‘endangered’ and ‘vulnerable’ species. It should be noted that under the Pesticides Act Part 2, Division 1, Section 9, only threatened animals and not plant species are implicated for the wilful or negligent use of pesticides. Part 5A of the TSC Act describes a Threatened Species Priorities Action Statement. A Priorities Action Statement sets out recovery and threat abatement strategies, promotes the recovery of a threatened species and seeks to manage each key threatening process. N AT I V E V E G E TAT I O N AC T 2 003 The Native Vegetation Act 2003 is administered by the NPWS and is used to manage native vegetation for future generations The Act regulates the clearing of native vegetation on all land in NSW except for land listed in Schedule 1 of the Act. Excluded land falls into the following categories: • national parks and other conservation areas • state forests and reserves • urban areas. Native vegetation is classified as any species of vegetation that existed in NSW before pastoral settlement, including trees, saplings, shrubs, scrub, understorey, groundcover or wetland plants. Clearing is defined as cutting down, felling, thinning, logging, removing, killing, destroying, poisoning, ringbarking, uprooting or burning native vegetation. VERTEBRATE PEST CONTROL MANUAL 38 LEGISLATION Exe m pt ions in relat ion to p est an imal co ntro l Pest animal control is considered to be a routine agricultural management activity (RAMA) under the Native Vegetation Act 2003, Part 2, Section 11, subsection (1c). Native vegetation can be cleared to the minimum extent necessary without approval, when required to control pest animals under an eradication order or pest control order under Part 11 of the Local Land Services Act. For more information on the Native Vegetation Act 2003 refer to www.environment.nsw.gov.au/vegetation/nvact.htm D E E R AC T 2006 The Deer Act 2006 clarifies the ownership and management of captive deer and provides for the regulation of deer that are not captive and prohibits the release of captive deer. The relevant sections of the Deer Act 2006 and Regulation 2008 are summarised below. This summary is not intended to replace or interpret the Deer Act 2006 and Regulation 2008. LEGISLATION 39 Table7: Summary of relevant sections of the Deer Act 2006 and Regulations 2008 Deer Act 2006 PART 1 – PRELIMINARY SECTION WHAT IT DOES Section 4 Ownership of deer (1) A deer that is held in captivity may be bought, sold or otherwise dealt with or disposed of. (2)If a deer ceases to be held in captivity, all property in the deer is immediately extinguished. (3)If a person captures a deer that is not held in captivity, the person becomes the owner of the deer. (4)Despite subsections (2) and (3), if a person other than an authorised officer captures a deer within 2 kilometres of the enclosure or other place (not being a vehicle) in which the deer was last held in captivity, property in the deer is not extinguished. (5)Despite subsections (2), (3) and (4), any of the following persons (but no other person) may kill a deer that is within 2 kilometres of the enclosure or other place (not being a vehicle) in which the deer was last held in captivity: (a) an authorised officer, or (b) an occupier of land, or (c) a person authorised by a person referred to in paragraph (a) or (b). Section 6 Offence of releasing deer (1) A person must not cause or permit the release of a deer from captivity. (2)It is a defence to prosecution for an offence under subsection (1) if the defendant can demonstrate that he or she took all reasonable steps to prevent the release of the deer and, after the release, took all reasonable steps to capture or kill the deer. PART 2 – DEER CONTROL ORDERS Section 8 Orders requiring deer to be controlled The Deer Act allows for the gazettal of a deer control order. A deer control order may require that the occupier of the land specified in the order do either or both of the following: (a)ensure that deer on the land (other than deer held in captivity) are controlled in a manner and in the circumstances specified in the order and within the time specified in the order, (b)notify the Minister, in the manner specified in the order, as soon as practicable after becoming aware of the presence of deer on the land (other than deer held in captivity). Deer Regulation 2008 Clause 4 – Authorised Officers For the purposes of section 17 (1) of the Act, persons appointed as authorised officers under Section 165 of the Local Land Services Act 2013 are prescribed. P R OT E C T I O N O F T H E E N V I R O N M E N T O P E R AT I O N S AC T 1997 The Protection of the Environment Operations Act 1997 (PEO Act) principally deals with the regulation of activities that have the potential to pollute or otherwise harm the NSW environment. The Act is administered by EPA. Most NPWS rangers are authorised officers under the PEO Act. As in the case of authorised officers under the LLS Act they have certain powers that support the purpose of the PEO Act. Under Chapter 7, of the EPO Act authorised officers have powers to searching premises, demand name and addresses and record evidence. In relation to pesticide use and the destruction of pest animals this Act may impose some liability in terms of the pollution of waters. Authorised officers should be aware of Section 120 of the Act which states: VERTEBRATE PEST CONTROL MANUAL 40 LEGISLATION Section 120 Prohibition of pollution of waters (1) A person who pollutes any waters is guilty of an offence. (2) In this section: pollute waters includes cause or permit any waters to be polluted. Note: the pollution of waters includes, but is not limited to: • placing any matter (whether solid, liquid or gaseous) in a position where: (i) it falls, descends, is washed, is blown or percolates, or (ii)it is likely to fall, descend, be washed, be blown or percolate, into any waters, onto the dry bed of any waters, or into any drain, channel or gutter used or designed to receive or pass rainwater, floodwater or any water that is not polluted, or • placing any such matter on the dry bed of any waters, or in any drain, channel or gutter used or designed to receive or pass rainwater, floodwater or any water that is not polluted, if the matter would, had it been placed in any waters, have polluted or have been likely to pollute those waters. The implications for authorised officers are that: • any poisoned baits must be placed such they will not enter into waterways • any pest animals destroyed in or near waterways must be moved so that the carcass poses no risk of entering a waterway EPA guidelines for the disposal of animal carcasses state: If the carcasses must be disposed of on-site, the following points should be considered. It is preferable to have: • a burial area at least 100 m away from houses and watercourses • the pit base at least 1 m above the level of the watertable • heavy soil of low permeability and good stability • good access to the site for earthmoving machinery and stock transport unless the stock are to be walked in for slaughter. Avoid: • sites sloping towards watercourses • areas that are likely to drain to watercourses or groundwater. Note: that the disposal location and quantity of carcasses may trigger the requirement for a waste facility licence under Schedule 1 of the Protection of the Environment Operations Act 1997 except in the case of an emergency mass animal disposal program which would then trigger emergency provisions.

All land managers have an obligation to manage these declared pests on the land they own, occupy or manage. It is the responsibility of the LLS to enforce a general destruction obligation requiring the occupier of controlled land to eradicate these declared pests. Occupiers of land in NSW are not obliged to control other introduced pest animals such as foxes, hares, feral cats, feral goats, feral horses, feral donkeys, and non-native rats and mice. However, these species may have significant negative impacts on the environment and agricultural production in many areas. As such extensive control measures are undertaken to address these impacts. Native birds such as sulfur-crested cockatoos and galahs are protected state-wide but a general exemption exists in the Central and Western Divisions. Crows and ravens (five species) are declared locally unprotected in all counties of the State except those of North Cumberland, Cumberland and Camden, where they are protected. The householder has the responsibility for rat and mouse control in urban areas, and control is often carried out by private pest control firms. When mice reach plague proportions in rural areas, individual land managers may attempt control. LLS and NSW DPI may provide advice on control. Domestic dog issues are handled by local government under the Companion Animals Act 1998. Dingoes are the only native mammal not protected under the NPW Act. If land managers wish to control other native animals such as kangaroos, they must apply for a permit from the NPWS. NPWS manages pests on its estate (such as national parks and nature reserves) and also develops and implements strategies for invasive species that threaten biodiversity. NPWS management is focused on areas where native animals and plants are the most threatened, other park values are affected, or where pests are likely to affect neighbouring lands. Two legislative instruments drive the focus of activities. Under the NPW Act activities are undertaken to protect the environment and manage pest animals on NPWS estate. Under the TSC Act threats to biodiversity particularly threatened species are managed by listing key threatening processed impacting threatened species and then preparing and implementing Threat Abatement Plans and Species Recovery Plans & Priority Action Statements. ADMINISTRATION 43 LO C A L L A N D S E R V I C E S Ver tebrate pes t wor k Each LLS may have a Vertebrate Pest Work Plan for rabbits, feral pigs and wild dogs in its district as a part of their documented planning, monitoring and control work regarding pest animals from the previous Livestock Health and Pest Authorities operating in their region. The purpose of these Vertebrate Pest Work Plans was to help the LHPAs set strategic direction and develop clearly defined control strategies and associated policies for each major pest species. They also: • allow LHPAs to articulate their plans and policies to ratepayers, the general public, and governments for accountability reasons • allow LHPAs to measure progress in vertebrate pest control by the use of key performance indicators and a management information system. The recent formation of 11 LLS regions under the LLS Act specifies the requirements for both State-wide and Local Strategic Plans which include animal pest management, control and eradication. Proper t y ins pec t ions: Po ints to co n sid er Inspecting properties is one of the major functions of an authorised officer - an officer is authorised by the LLS after having satisfactorily completed the relevant training to determine whether the LLS Act is being complied with. Inspection procedures must, therefore, be clearly understood. Property inspections are usually the best means of obtaining information and may be done on a property-by-property basis, or over large areas by aerial inspection. A systematic approach to property inspections is recommended for the following reasons: • cuts down unnecessary travel time • specific areas can be targeted and land managers are less likely to feel targeted or singled out • highlights problem areas and facilitates the planning of group programs. A notice of inspection must be given prior to each property inspection, as per Section 191 of the LLS Act and an inspection report should be issued for each inspection. This inspection report will define the level of infestation for each pest and also recommend control methods to reduce the infestation to acceptable levels. A sequential flow of the property inspection process is given in the following text and in Figure 1. The definitions used for infestation levels are given in the section Abundance indicators for vertebrate pest control, see page 47. Step 1 Inspect the property for the presence of pests and to determine what control measures are being carried out. a. Acceptable level of infestation (satisfactory management) – Re-inspection occurs in the LLS’s timetable. This is the goal to which LLS should be working for every property. b. Light to moderate infestation – the occupier or owner is advised of their VERTEBRATE PEST CONTROL MANUAL 44 ADMINISTRATION responsibilities under the LLS Act, and advised on how to control the pest animal(s) present. Sufficient time is allowed for implementing effective control prior to reinspection. c. High level of infestation – the occupier or owner is advised of their responsibilities under the RLP Act, and advised on how to control the pest animal(s) present. Sufficient time is allowed for implementing effective control prior to re-inspection. The occupier or owner is also required to submit a management plan that is acceptable to the authorised officer if the timeframe that is reasonable for effective control is greater than 2 months. This plan must be submitted within two weeks of initial inspection. If the occupier or owner fails to submit an acceptable plan the authorised officer will set timeframes for completion. Step 2 Re-inspect the property within the timeframes specified from the first inspection report or agreed to by the occupier or owner. a. Program complete – The specified control has been effectively carried out. No further action is required. Re-inspection occurs in the LLS’s timetable. b. Control program partially completed – Issue an individual eradication order which details the control methods to be used for the pest animal(s) and the date to complete program by. c. Control program not implemented – Issue an infringement notice and an individual eradication order. The order details the control methods to be used for the pest animal(s) and the date to complete program by. Step 3 Re-inspect the property within the timeframes specified in the individual eradication order. a. Program complete – The specified control has been effectively carried out. No further action required. Re-inspection occurs within 12 months to ensure ongoing compliance. b. Control program partially completed – Issue infringement notice and re-issue an individual eradication order which details the control methods to be used for the pest animal(s) and the date to complete program by OR re-issue an individual eradication order which details the control methods to be used for the pest animal(s) and the date to complete program by and commence prosecution. c. Control program not implemented – Issue an entry notice for the LLS to complete the program and charge the occupier or owner for the program OR re-issue individual eradication order which details the control methods to be used for the pest animal(s) and the date to complete program by and commence prosecution. LLS should also impose a charge to cover the reasonable expenses of any action taken by an authorised officer as a consequence of the occupier or owner failing to take any action the occupier or owner is required to take under Sections 150 and 151 of LLS Act. LLS will have an internal structure for approval of issuing infringement notices, eradication orders and entry notices.

Flowchart for the property inspection process, including regulatory action, for vertebrate pests. VERTEBRATE PEST CONTROL MANUAL 46 ADMINISTRATION R e co rding Once a property inspection has been carried out, the information must be recorded in the FARMS pest module against the holding. The use of tabulated material and maps can help the LLS see the progress, or lack of it, in a program of control for a particular property or a particular part of the district. Ab u n dance indicator s for ver tebrate pest co ntro l A property inspection report should be used by authorised officers of LLS as a means of recording vertebrate pest abundance and their potential to cause agricultural or environmental damage. Refer to Property inspections: points to consider on page 44. The use of a simple coding system developed by former Rural Lands Protection Board (RLPB) Ranger Erik Dekkers, is to indicate pest density and potential and is encouraged for property inspection reports. The advantages of this system are that: • it requires a minimum of effort in the field • information will be consistent • it is easy to read and comprehend • monthly and annual reports can include these tables with the totals of each category. This can be related to the previous year and the LLS’s objectives • if this system is adopted, information can be collated state wide and the ‘big picture’ can be more accurately assessed. Codes for rabbit density and potential for infestation. CODE DENSITY DEFINITION 0 nil No rabbits. 1 low Few or no sightings and/or little active sign. 2 medium 3 high Some rabbits seen at any time and/or much active sign. Rabbits seen at any time and much sign of activity (active warrens, dung hills, scratchings etc. Potential: potential is indicated by the factors that contribute to the quick build-up of rabbits, i.e. warrens, logs, blackberries, boxthorn, etc. and pressure from nearby heavily infested areas. CODE DEFINITION A No factors present. B Little harbour, single holes, easily destroyed. C Significant harbour, warrens, burrows, logs, bushes, etc. which with concentrated effort could be eliminated. D Intractable harbour, i.e. areas where it is impossible to eliminate all harbour, for example, Rocky hills, steep gullies, etc. The aim is to reach ‘OA’ grading codes for feral pig and wild dog density. ADMINISTRATION 47 Feral pigs CODE DENSITY DEFINITION 0 nil No pig evidence or sign. 1 low Very few sightings, very little fresh sign. 2 medium Some sightings and obvious fresh signs. 3 high Regular sightings and abundant fresh signs. Wild dogs CODE DENSITY DEFINITION 0 nil No sightings. 1 low Few tracks and sign, very few sightings, very little predation. 2 medium 3 high Abundant tracks and sign, howling heard at night, regular sightings and/or some predation. Abundant tracks and sign, howling heard at night, regular sightings and/or significant predation. A formal record of inspection may need to be presented during court cases, so it should include all relevant detail. For rabbits, note the number of animals seen, number of fresh signs, number and state of activity of warrens present, and the areas of property infested. Numbers seen is an important indicator of density when related to the time of day. For example, if rabbits are seen around midday it would indicate a high density, whereas if they are not seen until late afternoon it would indicate a low to medium density. If pigs are present, note the numbers seen and number of fresh signs, and decide whether pigs are living on the property or only moving in daily to feed. Report the effectiveness of any control work that has been done. Field notebook Every authorised officer should carry a pocket or stenographer’s notebook in the field. The field notebook provides a ready reference that will be invaluable for writing reports for the Team Leader, recalling details of discussions between land manager and authorised officer, and comparing degrees of infestation before and after control. More importantly, the notebook can be referred to as a memory aid during legal proceedings and should therefore be kept for at least three years after the final entry. The field notebook should be completed during the inspection or soon after and are referred to as contemporaneous notes. The completed entries should also refer to the inspection report. M ont hy repor t s Each authorised officer employed by an LLS may be required to submit a monthly report to the Team Leader. This report should be a concise summary of the officer’s work for that month. Pros ecut ions Prosecutions are covered in the Certificate IV in Government Statutory Compliance training and will not be covered here. VERTEBRATE PEST CONTROL MANUAL 48 ADMINISTRATION I nd e m nit y ver s us cons ent fo rms Indemnity and Consent Forms should be kept for a minimum of three years so that they can be correlated with the vertebrate pesticide usage and supply record in case of legal action. I nd e m nit y For m – is s uing p estic id e b aits to a p rivate lan d m anager Before supplying 1080, pindone, bromadiolone, coumatetralyl and RHDV bait or strychnine cloths, the ACO must get the person being supplied baits to sign an Indemnity Form that releases the LLS ACO and the LLS from any liability for accidental poisoning on the land manager’s property. This also applies in situations where the ACO is employed by a government department, Wild Dog Destruction Board or any other public authority and is supplying these baits to private land managers. The ACO should explain to the person being supplied baits what is contained in the Indemnity Form and ensure that the person signing understands that it is a legal document. The Indemnity Form is either filled out by the person signing the form or they can request help filling out the form from the ACO or someone else. Once signed, a copy of the Indemnity Form must be provided to that person and a copy kept on file by the LLS or other public authority. An ACO must only issue 1080 bait material to a person who is the owner, occupier, manager or authorised agent of the owner or occupier of the land on which the 1080 baits are to be used. If the authorised agent is not known to the ACO, then a ‘letter of introduction’ from the occupier is required. Local government and other government agencies should have an Indemnity Form signed by the person in charge of, or responsible for, the baiting. That person will sign an Indemnity Form ‘for and on behalf of’ their agency if the agency is laying the bait. A person who owns or occupies more than one property must complete a separate Indemnity Form for each property or program before any 1080 bait may be used on the specified property. The minimum information that should appear on an Indemnity Form is: • name and contact information of the authority or agency issuing the baits • specify which pesticide the form relates to • name and address and chemical accreditation card number details of the person authorised to lay the baits and name of authorised agent if applicable • name of property where baits are to be laid • an acknowledgement that the person has received the following information: 1.A copy of the PCO and relevant Schedule relating to wild dogs, foxes, feral pigs and rabbits for 1080. Customise as required for other pesticides. 2.The person has been advised that all baits must be laid in accordance with the label and PCO or permit as required. 3.The person has been reminded that other requirements under the Pesticides Act such as record keeping must also be complied with. ADMINISTRATION 49 • the names of persons that have or will be notified that the laying of baits will be occurring as required by notification conditions in the PCO or label or permit • acknowledgement of amount and type of bait material received, for which pest species for use on stated property • acknowledgement of amount of signage received to identify baiting location and the area being baited in hectares • a statement indemnifying the authority or agency • section for the authorised person or agent and officer of the authority or agency to sign and date. Consent Form – laying 1080 baits at the request of a land manager Where the LLS or another agency lays 1080 baits at the request of the land manager or occupier, then a Consent Form must be completed. The LLS or agency officer undertaking the program is responsible for ensuring all legal requirements are met including notification, signage and pesticide use records. In the case of on-going programs Consent Forms should be renewed at least annually. The minimum information that should appear on a Consent Form for 1080 appropriate to the indicated species is: • name of the authority or agency undertaking the 1080 baiting and/or the installation and maintenance of ejector devices • name and address of the person authorising the laying of 1080 baits and/or the installation and maintenance of ejector devices • address of property and description of the area where the 1080 baits and/or the installation and maintenance of ejector devices will occur • how long the consent will be valid for • who will inform the occupier of every property which has a boundary within one kilometer of a baiting location of baiting dates and who will erect and if necessary maintain the required 1080 poisoning notices • the location of baits and/or ejector devices upon their property have been clearly identified and mutually agreed to • the person giving the consent acknowledges – the requirement not to disturb the bait locations and/or ejectors in any way –their responsibility to restrict domestic dogs from the vicinity of the 1080 bait locations and/or ejector devices –their responsibility to keep the baiting location for rabbits and feral pigs free of livestock until the poisoned bait material has been picked up or thoroughly covered with earth –their responsibility to inform those persons entering their property, with their permission, of the presence and danger to domestic pets or livestock killed or injured by 1080 buried bait and/or ejector devices –that they are not entitled to any compensation for any domestic pets or livestock killed or injured by 1080 buried baits and/or ejector devises • the authorised officer undertaking the 1080 baiting and/or the installation and maintenance of ejector devices will undertake the 1080 poisoning program strictly in accordance with the conditions of the relevant PCO and label • section for the owner/occupier to sign and date and get witness to sign. VERTEBRATE PEST CONTROL MANUAL 50 ADMINISTRATION Co nt rac t wor k If the LLS or other agency carries out contract work for a public land manager or other organisation such as a council, then the land manager or other organisation does not sign a Consent or Indemnity Form. The contract will determine the arrangements. However, if baits are being transfer from one party to another party an indemnity of consent form is always required. R e co rd keeping Where an ACO is laying baits for a land manager or on contract, a record of the bait laid has to be made and kept as required by the Pesticides Regulation 2009. A copy is kept by the ACO’s agency and another given to the land manager or contract agency. St at utor y power s Where the LLS lays baits as part of its statutory power to enter and conduct a control program under Step 3 of the property inspection process (see under Property inspections: points to consider) no Indemnity or Consent Form is required. W H AT TO D O I F T H E R E I S A CO N F L I C T O R M I S U S E O F A PESTICIDE In all instances the ACO should discuss the matter with their 1080 Supervisor. Where a misuse has occurred the incident needs to be reported to the EPA. ISSUING BAITS Baits may be issued only after an approval by the ACO has been given and the occupier has received the relevant PCO and signed an Indemnity Form.

VERTEBRATE PEST CONTROL MANUAL 52 ADMINISTRATION Initial N AT I O N A L PA R K S A N D W I L D L I F E S E R V I C E St rategies NPWS have regional pest management strategies developed in consultation with the community. The strategies aim to minimise the adverse impacts of pests on biodiversity, protected areas and the community. They achieve this by identifying the highest priority programs and focusing on these, ensuring that actions are achievable, and delivering measurable outcomes. The strategies recognise that pest species are a problem across the landscape. Programs are developed and often carried out in collaboration with neighbours, other government agencies, LLS, local councils, regional pest committees, universities and community groups. Pro gram s Pest management programs are defined by; • Reserve: where the program is taking place • Site name: clearly identifies where in the reserve(s) • Target pest animals or weeds: may be multiple species • Asset at risk: ecological, heritage, agricultural, economic • Aim of control: eradication, containment or asset protection • Action: control techniques and monitoring • Priority: critical, high, medium, low Prioritisation ensures resources are given to programs and actions where it is most needed for protection of NPWS assets (e.g. biodiversity) and our neighbours’ assets (e.g. livestock). Four critical priorities are: • Threatened Species Conservation • New and Emerging pest species • Economic Impacts on neighbours • Health and Disease I m p l e m ent ing, keeping t rac k an d rep o r tin g Annual programs to implement the regional strategies go into Region Operations Plan. Resources utilised including finances are entered into the NPWS Asset Management System Pest and Weed Information System Component. Program and action are also tracked spatially through linking to the Pest and Weed Information System GeoDatabase More Information is available at www.environment.nsw.gov.au/pestsweeds/index.htm ADMINISTRATION 53 VERTEBRATE PEST CONTROL MANUAL 54 ADMINISTRATION Poisons & fumigants This section provides information on the preparation and use of pesticides to control vertebrate pests. It also covers the authorisations to obtain, store and supply the RCP 1080, pindone concentrate and RHDV. These pesticides have significant economic, social, public health and environmental benefits, however, many vertebrate pesticides are toxic to non-target species and there are environmental risks associated with their use. Consequently they are strictly regulated in NSW. It is essential that suppliers and users of vertebrate pesticides comply with legislation for pesticide use. Vertebrate pesticides need to be used in a safe, efficient and economical manner to maximise their benefits and to ensure their continued availability. Pesticides are just one element of pest management and should be used in combination with other techniques as part of an integrated pest animal management program. Ve r te brate pes t icides us e d in NSW A number of RCPs are available for use in NSW under AgVet Code 1994 Permits (APVMA). A summary of the main vertebrate pesticides currently registered and permitted for use in NSW are listed in Appendix A. It should be noted that ACO or CPO status is only required when handling or storing the RCPs pindone, 1080 or RHDV. ACC E S S TO R E S T R I C T E D C H E M I C A L P R O D U C T S The PCOs under Section 38 of the Pesticides Act allow the possession of RCPs such as 1080 liquid concentrate, pindone liquid and powder concentrate and RHDV for the preparation and sale of baits by ACOs subject to the conditions specified in the relevant PCO or APVMA permits. An ACO is a person who is a member of staff of a LLS, a Wild Dog Destruction Board, NSW DPI, OEH or other NSW public authority and has undergone specific training and received accreditation in the storage, preparation and use of these RCPs. The requirements to gain and maintain accreditation as an ACO are outlined in the PCOs. Acce s s ing pindone liquid an d powd er co n centrates o n ly A Commercial Pindone Officer (CPO) is a person who is a private contractor or other nongovernment person who is permitted to access pindone liquid and powder concentrates ONLY after the person has sought registration from the EPA after undergoing specific training and receiving accreditation in the storage, preparation and use of pindone concentrates. The requirements to gain and maintain accreditation as a CPO are outlined in the PCO for Commercial Pindone Officers. G E N E R A L P E S T I C I D E S TO R AG E FAC I L I T Y R E Q U I R E M E N T S Where the provision for bait preparation is not required, general pesticide storage for vertebrate pesticides as detailed in WorkCover’s Code of practice for the safe use and storage of chemicals (including pesticides and herbicides) in agriculture and AS 2507 The storage and handling of agricultural and veterinary chemicals are the standard for compliance. POISONS & FUMIGANTS 55 These facilities will only be used to store manufactured baits, baits that have been prepared elsewhere or ejector capsules. These stores may also hold fumigants and other pesticides, such as herbicides and locust insecticides. The general pesticide storage facility requires the following features: • at least three metres from any office not connected with storage and handling of pesticides • non-combustible materials for store itself • at least five metres from any ignition source • cross-flow ventilation by vents in opposite walls above bund height • concrete or impervious floors with drainage into a sump • concrete or impervious door sills • a bund made from concrete or impervious material, able to contain a spillage of at least 110% of the largest container or 25% of the total volume of liquid being stored, whichever is largest* • impervious shelving or spill control trays on shelving • lockable door • lighting sufficient to allow labels to be read i.e. at least 200 lux, but not so that labels are exposed to direct sunlight, which causes deterioration • spills kit • fire extinguisher(s) • access to water for washing, particularly an eye wash • emergency contact details – Poisons Information Centre, 000 for ambulance, police and fire brigade, local hospital and doctor, SES, WorkCover. The best practice for operation of the pesticide storage facility encompasses: • segregation of classes of chemicals from one another e.g. insecticides from herbicides; veterinary chemicals from both; and flammable from non-flammable products by at least three metres • storage of liquid containers beneath containers with dry formulations e.g. powders and granules • keeping containers sealed and labels intact • not decanting • use of older stock first – this is facilitated by the dating on the storage register • opening flammable liquid containers, Dangerous Goods Class 3, outside • securing leaking or damaged containers within a larger drum or by decanting into a secure container and transferring the label or label information to the new container • keeping the storage clear of residues and combustible wastes • clearing the ground around the store of combustible vegetation or refuse for at least three metres •Not storing or handling the chemicals in such a way that block entrance or exit in an emergency. * There may be instances where bunding is not required such as when all pesticides can be stored in a lockable cabinet with appropriate spill trays.

Records must be made within 24 hours and kept for at least three years from the last date recorded in it. The usage and supply record may be a hard copy or electronic. Only ACOs who use the vertebrate pesticides may make or approve entries into the usage record, subject to ACOs who work together having some prior agreement. Au d i t ing ver tebrate pes t ic id es • For 1080 liquid concentrate monthly audits must be undertaken by the ACO and submitted to the 1080 supervisor. • For all other 1080 manufactured products a monthly audit is undertaken by the ACO if 1080 manufactured products have been used in the previous month. • The 1080 supervisor will undertake twice yearly audits of all 1080 liquid concentrate and manufactured products. • For pindone liquid and powder concentrates and manufactured products a minimum of a quarterly audit is undertaken by the ACO. It is recommended that the 1080 supervisor be shown the results of this audit and undertakes an annual audit as a minimum. • For all other vertebrate pesticides a minimum of a yearly audit is undertaken by the ACO responsible for those pesticides. It is recommended that the 1080 supervisor be shown the results of this audit.

POISONS & FUMIGANTS 57 ACC I D E N T A N D I N C I D E N T R E P O R T I N G Following a risk assessment of each pesticide storage facility should have an Emergency Plan that details steps to take in event of fire or other incident at the facility. The Emergency Plan plan may include: 1. Who to contact 2. Activation procedures 3. Evacuation procedure 4. Control and containment of spills and leaks 5. Fire-fighting procedures 6. Protection of persons engaged in emergency assistance 7. Assistance by emergency authorities such as police and fire brigade 8. Emergency contacts 9. A list of individuals and organisations to be provided with a copy of the emergency plan. All incidents that require activation of the Emergency Plan procedures should be recorded and reported to WorkCover or other relevant authority. TOX I C I T Y Toxicity is the degree to which a substance can damage an organism. Most substances are toxic under some circumstances. When the amount of toxin exceeds the body’s ability to excrete or inactivate it there is a risk to health. Users of poisons must have an understanding of toxicity: • for their safety • to control the target pest economically • to minimise the risk to non target animals. The toxicity of a poison varies with: • The species. • The weight age and health of the animal. • The method of administration. Poisons are, generally, more toxic when ingested than when applied to the skin. M eas ur ing toxicit y Toxicity is measured by use of the lethal dose for 50% of a group of test animals under experimental conditions and is known as the LD50. Let hal Dos e, 5 0 % ( L D 50 ) The Lethal Dose 50% (LD50) is the amount of the active ingredient of a formulation of poison, expressed in milligrams per kilogram (mg/kg) live weight that will kill 50% of a group of animals of one species under experimental conditions. The LD50 of a poison is used to compare different poisons and the effect of one poison on different animal species. The lower the LD50 the more susceptible the species is to the poison. VERTEBRATE PEST CONTROL MANUAL 58 POISONS & FUMIGANTS The LD50 benchmark is used as there are always individual animals of the one species that are more tolerant to a poison and this tolerance of one animal in a test group may skew the results of the average toxic dose for the rest of the group. This means that LD50 is not the lethal dose for all subjects; some may be killed by much less, while others survive doses higher than the LD50. Appendix 2 shows the LD50 for a range of species to sodium fluoroacetate (1080). Note the comparatively low LD50 for dogs, foxes and cats. Ab s olute Let hal Dos e ( LD 100 ) The Lethal Dose 100% (LD100) is the amount of active ingredient of a formulation of poison, in milligrams per kilogram (mg/kg) live weight that will kill 100% of a large group of animals of one species. The LD100 is more difficult to determine because there are always individual animals that are more tolerant to a poison. So an LD100 figure will depend on the number of highly tolerant animals in a test group and the sample size needs to be very large. Ap p licat ion of Let hal Dose rates The LD50 rate is the main method to determine the toxicity of a poison however it is not the amount of poison applied to pest animal baits. The aim of a baiting program is to kill all the target animals that consume bait. For example, the LD50 of 1080 for wild dogs is 0.1 mg/kg. Therefore, 1 mg of 1080 will kill 50% of wild dogs weighing 10 kg and 3 mg of 1080 will kill 50% of wild dogs weighing 30 kg. To ensure that the largest, most tolerant wild dogs die from eating baits poisoned with 1080 and to account for seepage and microbial breakdown in the environment, 6 mg of 1080 or 0.2 mL 1080 liquid concentrate is injected into wild dog baits. Acu te and chronic pois on in g Acute poisoning occurs when a poison is administered with a single lethal dose, such as a rabbit suffers acute poisoning by eating 1080 poisoned carrot bait. Most vertebrate pest poisons are acute poisons. The acute or immediate toxicity of a pesticide is reflected in the Poisons Schedule or poison warnings, which appear on the label. See Table 8. Chronic poisoning occurs when poisons are administered in smaller doses that have a cumulative long term effect that causes death such as pindone. Table 8: Poisons schedule. UNSCHEDULED VERY LOW TOXICITY NO HEADING REQUIRED 4 Varying toxicity Prescription animal remedy 5 Slightly toxic Caution 6 Moderately toxic Poison 7 Highly toxic Dangerous poison POISONS & FUMIGANTS 59 Pr im ar y and s econda r y p o iso n in g Primary poisoning occurs when the target animal consumes a toxic substance. For example, a rabbit suffers primary poisoning by eating 1080 poisoned carrot bait. Secondary poisoning refers to one animal being poisoned after consuming the flesh of another animal which has digested the poison such as when a carnivore consumes the carcass of a poisoned animal. The pesticide 1080 may persist in the muscle tissue and stomach contents of poisoned animals long after death. Because most canids are highly susceptible to 1080 poison, it is highly likely that sufficient poison remains in the carcass of a poisoned rabbit to cause the death of a working dog. Secondary poisoning may be a significant risk factor to working dogs and domestic pets immediately after a baiting program and may remain a threat longer in cold or dry conditions that retard the breakdown of pesticide residues. The Pesticide Control (1080 Liquid Concentrate Bait Product) Order 2010 (1080 PCO) for 1080 liquid concentrate and bait products requires users cover or collect all uneaten bait material and poisoned carcasses and to dispose of them by deep burial to reduce the risk of secondary poisoning of non-target animals. Birds of prey and other avian scavengers are less likely to be at risk of 1080 poisoning because of their lower susceptibility to the pesticide and their reduced ability to consume enough of the carcasses, however there may be a risk of fatalities with use of pindone. VERTEBRATE PEST CONTROL MANUAL 60 POISONS & FUMIGANTS 1 0 8 0 ( S O D I U M F LU O R O AC E TAT E ) I nt ro duc t ion 1080 is a S7 (Highly Toxic, Dangerous Poison) used to control wild dogs, foxes, rabbits and feral pigs. It was discovered by Belgium researchers in 1896 and was first used around 1944 as a rodenticide in the United States. It was introduced into Australian for rabbit control programs in the early 1950s. In Australia 1080 is the synthetic form of sodium fluoroacetate – the latter occurs naturally in 41 plant species of the family Fabaceae including 39 species of Gastrolobium and two species of Acacia. These species grow in Western Australia, across northern Australia in the Northern Territory and in central Queensland. Phys ical and chem ical pro per ties In its pure form, 1080 is a synthesised organofluorine compound that is stable in the absence of water. It is an odourless white powder that is highly soluble in water. It produces a clear solution when mixed. Commercial 1080 liquid concentrate contains 1 part 1080 powder to 30 parts of water. A dark blue dye is added to distinguish the resulting solution from water. 1080 liquid concentrate is not soluble in organic solvents such as fats or oils. It becomes unstable above about 110°C and decomposes at about 200°C. Once in solution, 1080 is readily degraded in the environment by microbial action. M o d e of ac t ion 1080 can be absorbed through the stomach, intestines, lungs, mucous membranes, eyes and open cuts. It is not readily absorbed through healthy skin. 1080 acts by disrupting the ‘Krebs cycle’, the complex metabolic pathway in the mitochondria that breaks down food providing glucose and energy for cells to function. Once the energy reserves are depleted, death occurs fairly quickly from heart or respiratory failure. Cardiac failure is the most common cause of death in herbivores poisoned by 1080. Carnivores experience central nervous system disturbances and convulsions as their energy supplies are exhausted, eventually leading to respiratory failure. In omnivores, death tends to results from disturbances of both the heart and central nervous system. The heart, brain and lungs are organs significantly affected by 1080 due to their high energy usage. The diaphragm is also affected. Death usually occurs within 4 to 24 hours after ingestion. Animals that eat sub-lethal doses of 1080 may show mild signs of poisoning and fully recover as fluoroacetate is readily metabolised, for example by defluorination, and most traces are generally excreted within a week. There is no known antidote for a lethal dose of 1080. However, some animals seen ingesting 1080 baits may be saved by urgent and immediate veterinary treatment. See Appendix D – First aid for working dogs and other domestic animals. POISONS & FUMIGANTS 61 Advant ages of 1 0 8 0 as a po iso n • Cost – 1080 poison is relatively cheap. This is important for cost-effective vertebrate pest control and in removing any temptation for unscrupulous people to seek less acceptable ‘home-made’ alternatives. • Convenience – 1080 bait products are easily prepared and the clean-up process is quick, safe and efficient. • Availability – Currently 1080 is the predominate pesticide used as there are limited alternative pesticides available for vertebrate pest control in NSW. S ens it ivit y and s us cep tib ilit y to 1080 Species vary widely in their sensitivity to 1080. The susceptibility of different animals during 1080 poisoning programs depends on the amount of 1080 consumed and the body size of the animal. Carnivores, especially dogs and foxes, are the most sensitive to 1080 poisoning, followed by herbivores, with birds and reptiles less sensitive. Introduced species are generally more sensitive than native wildlife. More information on susceptibility of a range of animals is available in Appendix B. Environm ent al fate Studies, both in Australia and New Zealand demonstrated that 1080 is rapidly degraded by microbial action. Degradation occurs by enzymes defluorinating fluoroacetate. The rate of detoxification in baits depends on: • bait type • placement of baits, such as buried or exposed on the surface • soil temperature and moisture • microbial action. In laboratory experiments, the amount of 1080 remaining in soils was reduced to 50% after 10 days at 23°C, 30 days at 10°C and 80 days at 5°C. Leaching experiments in soil showed that traces of 1080 might be leached through soil, particularly if heavy rainfall occurred shortly after 1080 was applied. Most soils can be expected to contain micro-organisms such as Pseudmonas, Fusarium and Pennicillium capable of degrading 1080. This means that residues of 1080 that leaches from baits or carcasses should have little persistence in soils. Buried fresh meat baits may lose at least 85% of 1080 content after 7 days in cool conditions. It is also noted that 1080 ingested by animals is rapidly metabolised and excreted with only low levels retained in the carcass. Breakdown of 1080 residues occurs rapidly in water. At 21°C, micro-organisms in water degrade 1080 in two to six days. At lower temperatures, microbial action is slower and degradation may take two weeks, or longer, at temperatures below 7°C. The solubility of 1080 means that is also rapidly diluted in water. This dilution effect, especially in flowing water, quickly reduces the level of 1080 to insignificant concentrations compared to the time taken by micro-organisms in the water. M-44 ejector capsule are likely to remain viable for a number of years due to capsules being sealed and therefore limited opportunity for degradation of 1080 due to lack of contact with soil or water VERTEBRATE PEST CONTROL MANUAL 62 POISONS & FUMIGANTS Is 1 0 8 0 hum ane? Death from 1080 results either from cardiac failure or convulsions, respiratory paralysis and central nervous system dysfunction (canids), or a combination of both. Many species show symptoms consistent with central nervous system dysfunction ranging from tremors and muscular spasms, through to running, ‘paddling’, convulsions and vocalising. Although 1080 poisoning causes central nervous system dysfunction animals eventually loose consciousness in an equivalent way to human epileptics undergoing seizures. It is recognised that some community uncertainty regarding 1080 remains, in part because its effect on the central nervous system gives animals the appearance of being distressed. It is also recognised that current technology cannot yet provide objective measures to adequately address these community concerns. Currently strict legislative controls allow the use of 1080 to reduce the impacts of rabbits, wild dogs, feral pigs and foxes on the community. In particular the agricultural and environmental sectors relies on its use until alternative toxins are developed. M i n i mis ing t he r is k to no n - targ et an imals Differences in susceptibility to 1080 between species means that application rates can be varied to kill some species and minimise the risk to others. For example, a single bait to kill a fox may not kill a wedge tailed eagle. Differences in dietary preferences between species can be exploited by selecting bait substrates that are more attractive to target species and less attractive to non-target species. Bait placement strategies can utilise feeding behaviours between species such as burying baits for wild dogs and foxes to make baits less available to non-target species. There is, however, no single procedure that guarantees 1080 baits will always be totally target specific. Techniques to reduce the risk to non-target animals include: • monitor bait sites prior to baiting programs for non-target species activity • using the most appropriate bait size • using the most appropriate type of bait material • burying, tying down and dyeing baits • injecting liquid concentrate into the centre of freshly prepared meat baits • making baits attractive to pest species only • using fencing or bait stations that exclude non-target animals from bait sites • using M-44 ejectors as they require an animal to possess sufficient strength to exert an upward pull force to be activated and cannot be cached or moved • timing bait placement when pest species are most vulnerable and non-target animals are least vulnerable • using pulse baiting to reduce the opportunity for multiple bait take and caching by an individual animal, particularly predators such as foxes. Note: The non-target animals most at risk from 1080 poisoning are domestic dogs. See Appendix D for information First aid for working dogs and other domestic animals.

Audit ing 1 0 8 0 liquid co n centrate To undertake audits of 1080 liquid concentrate ACOs should measure by weight. Use a set of digital scales that will measure 6,000 grams, up to a 5 litre bottle, with 1 g graduations. To audit 1080 liquid concentrate, weigh the container of 1080 liquid concentrate when received and prior to use. Record this starting weight, it may be useful to put this weight on the container. As 1080 is used, weigh the container at the conclusion of each use. This will give you the quantity of 1080 used for baits. When the container is empty triple rinse. One millilitre of 1080 liquid concentrate = 1 gram Worked example 1. Audit of 1080 container contents prior to emptying contents Total weight of container + 1080 concentrate prior to use = 1080 g Weight of container + 1080 concentrate after use = 400 g Amount of1080 used = 680 g or mL I njec t ion gun For the preparation of boneless red meat baits, an accurate 1mL injection gun must be used. A plastic shield that fits behind the needle will protect the operator from 1080 liquid concentrate that may squirt back. Was hing and cleanin g p ro ced u res As 1080 liquid concentrate is very soluble in water, all equipment, trays and benches must be cleaned by washing with plenty of cold water. All equipment should be thoroughly rinsed and allowed to drain. When washing down in the field, waste water, bait and other waste should be buried in a pit or collected in a container marked 1080 and returned to the 1080 facility for disposal. ACOs should wear gloves, washable hat, overalls and rubber boots while washing equipment that has been contaminated with 1080. To safely remove the ACO’s PPE, wash the gloves, remove the hat and overalls first and then remove the gloves, then thoroughly wash hands and face with soap and water.

CO M P U L S O R Y DY E I N G O F 1080 L I Q U I D CO N C E N T R AT E AND POISONED BAITS The dyeing of 1080 liquid concentrate and all baits for rabbits and feral pigs is compulsory. A blue water soluble, food colouring dye is pre-mixed with the 1080 liquid concentrate when supplied. The reasons for dyeing baits are: • The distinctive blue colouring readily identifies the bait as being poisoned with 1080. • There is overwhelming scientific evidence that demonstrates bait uptake by rabbits and feral pigs is not affected by the normal quantities of dye used on baits and it reduces the uptake by birds. • The dye readily indicates where 1080 liquid concentrate moves throughout the bait preparation and distribution process. This should assist ACOs to improve work practices and reduce contamination of clean work areas by 1080 liquid concentrate. • The dye indicates the efficiency of the 1080 bait mixing process. POISONS & FUMIGANTS 69 Figure 5. 1080 rabbit bait blue with unpoisoned carrot (David Croft) B ait colourat ion 1080 liquid concentrate comes pre-dyed from the distributor. In NSW the colour is usually blue. When 1080 liquid concentrate is added to the bait product ensure that the poisoned product is sufficiently dyed. If the poisoned bait is not sufficiently coloured then a small quantity of dye may be applied to the poisoned bait in the mixer. Mixing rates will vary according to the bait type. The ACO will need to experiment with each bait type, making sure that the bait is not excessively dyed, because this may lead to bait rejection by some target animals. When baiting is to be carried out in areas known to be populated by satin bower birds a green dyed bait must be used. It is not known whether blue-dyed baits are eaten by satin bower birds, however, public perception would probably be that these birds would be attracted to blue-dyed baits. If there is uncertainty as to whether the satin bower bird is present in a district, these birds range mainly along the coast and hinterland, the ACO should discuss the distribution of this species of bird with their local NPWS office. ACOs can either purchase green dyed product from the manufacturer to bait in satin bower bird areas or add a yellow dye to the bait until it is a definite green, so that it can be readily distinguished from undyed bait. Suppliers of dyes suitable for use with 1080 liquid concentrate are provided in Appendix E.

When preparing 1080 poison bait the ACO must ensure that no unauthorised person(s) are in close proximity to ensure their safety and the security of the 1080 liquid concentrate being used. However, when an ACO is handling 1080 liquid concentrate or is mixing bait, they should notify office staff that they are in the 1080 facility and give an appropriate finishing time. If say 30 minutes after that finishing time has lapsed, then the office staff should check. 1 0 8 0 bait m ixer ( M oree M ixer) An enclosed bait mixer is the minimum standard for mixing 1080 liquid concentrate with baits for rabbits and feral pigs. The bait mixer provides for even mixing of 1080 liquid concentrate with baits and protects the operator from 1080 liquid concentrate and grain dust. Figure 6. Enclosed bait mixer (David Croft) Using the bait mixer Ensure that all guards are in place and safety switches are working. The machine is loaded from the top through a square opening with a hinged lid. Maximum loads are 25 kg of carrots, 22 kg of grain or 16 kg of pellets. Meat baits are not to be used in the mixer. This lid must have a cut out switch so the mixer does not operate with the lid open. Poison application: A hand pump mounted on the mixer may be used to deliver the poison via spray nozzles that give an even, flat shaped spray. Alternatively the liquid concentrate may be poured over the top of the bait material and then thoroughly mixed to ensure all bait material is coated by the concentrate. POISONS & FUMIGANTS 71 Removal of poisoned baits: Poisoned bait is removed through an opening in the bottom of the bait mixer. The bait drops through this opening into appropriately labelled plastic bags, which are secured on hooks on each corner of the runners. M ixing in bags When mixing carrot or grain in small quantities such as 10 kg, it can be mixed manually in the appropriate 1080 bag. Measure the required amount of grain or carrot and mix with the required amount of 1080 (depending on species being targeted). This can be undertaken in the 1080 preparation room or in the field just prior to use. Figure 7.

Table 11 gives mixing rates per Schedule 4 for different quantities of rabbit poisoning. Only the listed bait materials may be used when preparing 1080 poisoned baits for rabbits: • carrots (preferred) •oats • manufactured pellets. Carrots are generally the most effective bait for rabbits, being used extensively throughout two-thirds of NSW, combining high acceptability with reasonable economy. Cut carrots manually or in a carrot cutter before 1080 liquid concentrate is applied. The carrots should be cut with a swift, clean action to produce pieces about 2 cm on a side and about 5 g in weight. Avoid small chaffy pieces that dry quickly or large chunks that rabbits find hard to eat. VERTEBRATE PEST CONTROL MANUAL 72 POISONS & FUMIGANTS Although carrots are preferred, oat grain has certain advantages in dry seasons because it is readily available, suitable for storage, easier to handle and does not deteriorate or require processing.

POISONS & FUMIGANTS 75 Field preparat ion an d mixin g o f 1080 baits 1080 baits may be prepared in the field providing the following conditions are met: • Only ACOs are permitted to handle 1080 liquid concentrate. • All safety equipment such as washable hat, overalls, gloves, respirator and plenty of water are taken to the site. • The 1080 liquid concentrate is transported in a sealed and locked metal or strong plastic box securely fixed to the vehicle. • All bait preparation, mixing and washing should be done over a shallow pit about 10 to 25 cm deep, to ensure any spills, chaff or blood are contained on site. • At the completion of bait preparation all equipment must be washed down before leaving the site. All rinsate must be drained into the hole and filled in when the job is finished. The filled in hole must be checked for any leakage and any subsequent rinsate reburied. • The pit must be clear of permanent and ephemeral waterways to avoid pollution. • It is advisable to place a 1080 sign at the pit site. • Alternatively, all rinsate may be collected into a hard plastic container labelled ‘1080 poison’ in large red lettering and transported to the 1080 facility for disposal. Back packs such as disused drench containers are not approved poisons containers and must not be used for use or storage of 1080 liquid concentrate. Cont ainer s and labellin g fo r 1080 p o iso n ed baits Under the Pesticides Act, 1080 bait material must be supplied to the user in an approved container impervious to the poison and of sufficient strength to prevent leakage arising from the ordinary risks of handling and transport. The ACO may only supply 1080 baits in either a plastic bag labelled in accordance with the various Schedules of the current 1080 PCO or in a container supplied by the manufacturer of registered bait products. Suitable plastic bags are a minimum of 100 microns (100 μm) thick and are printed with the required labelling, as specified in the Schedules of the current 1080 PCO. Each Schedule (condition 3.3) in the current 1080 PCO for the supply of baits by an ACO to an authorised user allows for manufactured 1080 bait product to be placed in an appropriately labelled plastic bag where the required quantities are less than the minimum sized manufacturer’s container. Suppliers of approved plastic bags for 1080 baits are provided in Appendix E. 1080 ejector capsules must be supplied in containers that comply with. section 18(1) of the Agricultural and Veterinary Chemicals Code Regulations. Attached to the container must be a printed label as per the Schedule of the current Pesticide Control (1080 Ejector Capsules) Order 2011. D is pos al of 1 0 8 0 contain ers an d u n u sed b aits Containers, including plastic bags, which have been used to contain 1080 baits must be disposed of by burial or burning.

VERTEBRATE PEST CONTROL MANUAL 76 POISONS & FUMIGANTS S U P P LY I N G 10 8 0 B A I T S S u p p ly to aut hor is ed perso n s An ACO must only supply 1080 baits to a person who is a: • landholder of the land on which the 1080 baits will be used, or their authorised agent and, who holds the required level of training as defined in the current 1080 PCO. Note: an exemption applies to the above training requirements for persons who occasionally apply 1080 in agricultural or forestry operations. However these persons may only use 1080 under the direct supervision of a person who holds chemical use accreditation at AQF3 level or higher. A person taking possession of 1080 baits must first complete and sign an Indemnity Form for each property on which baits are to be used. When an ACO is supplying 1080 prepared or manufactured baits to another ACO only the ACO who is taking possession of the 1080 prepared or manufactured baits needs to have completed a risk assessment for the program being undertaken. Ve r te brate pes t r is k as s essment g u id elin e An ACO may conduct a risk assessment to determine if it is appropriate to supply 1080 baits to any person. Risk assessments should consider threats on non-target species particularly domestic dogs, human health and the environment. ACOs must conduct a risk assessment of planned group baiting programs where baiting occurs less than the prescribed minimum distances provided in the current 1080 PCO, such as where a wild dog group baiting program agrees to place 1080 wild dog baits less than 500 m but no closer than 150 m from habitation. The following should be considered as a guideline only and is not an exhaustive list of risks that need to be considered when undertaking a baiting program. Authorised Control Officers should consider any specific or local issues that may constitute a risk. A risk assessment may assist to demonstrate that risks were appropriately assessed and recorded and that due diligence was exercised in relation to vertebrate pest control program. When undertaking a risk assessment, consider: 1. Can the requirements of the Pesticide Control Order or label be met? If not, then the program may not proceed. 2. Are there risks to human safety? Assess the risk and whether the program can proceed by minimising the risk to an acceptable level by, for instance, isolating with signage or fencing the area. 3. Are there risks to the environment (e.g. threatened, endangered or non-target species that are vulnerable or susceptible to 1080)? Assess the risk and whether the program can proceed by determining the measures acceptable to minimise the risk of baiting on the environment. 4. Are there risks to domestic livestock? Assess the risk and whether the program can proceed by considering methods of husbandry necessary to minimise the risk; such as removing grazing livestock from a paddock during a rabbit baiting program. POISONS & FUMIGANTS 77 5. Are there risks to domestic pets? Assess the risk and whether the program can proceed by minimising the risk to an acceptable level. For instance, will domestic pets need to be restrained or caged during the baiting program? 6. Are there risks to working or guard dogs? Assess the risk and whether the program can proceed by minimising the risk to an acceptable level. For instance, will working or guard dogs need to be muzzled during the baiting program? 7. Are there other risks not mentioned or risks that may have adverse outcomes such as negative media coverage of the program? If so, manage risks appropriately. Risk assessment templates are provided in Appendix C. This template may be used as a guide to record each risk and the management controls used to mitigate or minimise the risk to acceptable levels. The template may be amended to meet locally specific issues or hazards. Where a Conservation Risk Assessment has been undertaken and endorsed by an ACO such as for aerial baiting, there is no need for an additional risk assessment to be undertaken for that activity. A P P LY I N G 10 8 0 B A I T S D is t ance res t r ic t ions Minimum distances for laying 1080 baits have been set to minimise the risk to non-target animals particularly humans, domestic dogs and cats. If control is necessary in the areas excluded from baiting, other control methods must be used. Instructions relating to distance restrictions are contained in the current 1080 PCO. Public not ificat ion Persons who use 1080 baits on their own land or on public land are required to notify others before laying 1080 baits. The requirements for public notification are contained in the current 1080 PCO and it outlines who must be notified, how they are to be notified and when they are to be notified, before 1080 bait is laid. In addition to this, all public land Managers must have and follow a Pesticide Use Notification Plan. 1 0 8 0 pois oning not ices Persons using 1080 must erect notices before laying baits on any land. The notices must remain displayed for at least 4 weeks after the last day of baiting. Refer to the current 1080 PCO for details on where notices must be placed. Notices must specify the following: 1. that 1080 (wild dog, fox, feral pig or rabbit) baits are laid on this property, and 2. the dates on which 1080 (wild dog, fox, feral pig or rabbit) baits are first laid or the dates between which baits will be laid, and 3. contact details of a person that can be contacted to get details on the baiting program, and 4. a warning that non-target animals may be affected or that domestic dogs may be at risk. Authorities must keep adequate supplies of these notices for each animal species. Notices for ejector capsules should specify capsules as opposed to baits.

POISONS & FUMIGANTS 79 PINDONE I nt roduc t ion Pindone is a first generation anticoagulant used to control rabbits in areas where distance restrictions and the impact on non target animals and domestic pets make 1080 unsuitable. These include urban and closer settled semi-rural areas, golf courses, sporting fields and horticultural areas. Pindone has a long history of use in Australia; the pindone acid formulation was introduced into Western Australia in 1984. Both pindone acid and pindone sodium formulations are registered in Australia for use as a vertebrate poison to control rabbits. An advantage of pindone compared to 1080 is that there is an antidote for use where domestic animals may be exposed. Anticoagulants have a low level of hazard to humans and domestic animals when used according to the label. Pindone should be considered where: • rabbits are to be controlled in urban or closely settled areas and areas where 1080 is restricted from use • the land manager objects to the use of 1080 and is willing to use pindone • stock must be returned to the treated paddock soon after a control program. There are several registered products containing pindone; ready-to-use bait products and pindone powder and liquid concentrates. While ready-to-use baits are available through rural merchants and some LLS, the liquid and powder concentrate products are restricted for use by ACOs. Factory prepared baits include RABBAIT® oat bait and Aldi Bunnybait oat bait for rabbits®. Pindone concentrate is registered as Pindone-25 Rabbit Bait Rodenticide®, Pindone 25 Liquid Concentrate® or RABBAIT Liquid Pindone Concentrate® and must be used in accordance with the current Pesticide Control (pindone products) Order (Pindone PCO) and the pindone label. Phys ical and chem ical p ro p er ties Pindone is a green synthetic chemical product available in both powder and liquid formulations containing either pindone acid or pindone sodium. The main difference between the two is that baits prepared from pindone sodium may be expected to lose the toxicant more rapidly under wet conditions because the sodium salt is water-soluble, whereas pindone acid is water-insoluble. Pindone acid is mainly available in Western Australia. Pindone concentrates typically used by ACOs are Pindone-25 Rabbit Bait Rodenticide® powder containing 2.5% pindone as a sodium salt in an inert base of caster sugar and corn starch or as RABBAIT Liquid Pindone Concentrate® or Pindone 25 Liquid Concentrate®; the latter two also contain 2.5% pindone as a sodium salt in solution. M ode of ac t ion Pindone is a cumulative poison and reduces the clotting ability of blood by disrupting the vitamin K cycle. Animals die from internal haemorrhaging within 10 to 14 days after the initial dose. VERTEBRATE PEST CONTROL MANUAL 80 POISONS & FUMIGANTS At least three applications of pindone poison bait are required at 3–5 day intervals to ensure rabbits receive a lethal dose. Few rabbit carcasses are seen after poisoning, because most rabbits die in the warren, but rabbits may be active in the treated area for many days after eating the poisoned bait. Where possible carcasses should be collected and disposed of according to the pindone label. Symptoms of anticoagulant poisoning are: • haemorrhaging and bruising •anaemia •listlessness • general lethargy. S e ns it ivit y and s us cept ibilit y to pin d o n e Rabbits are generally more sensitive than other vertebrates to pindone, see Appendix B. Some raptors appear to share the high sensitivity of rabbits, based on results for wedgetailed eagles and brown goshawks. Kangaroos also appear highly sensitive, based on results for western greys. It should be noted that while pindone is considered a safer option than 1080, extra care must be taken in areas to be baited that are frequented by native wildlife. Baits should be contained in bait stations that prevent access by animals larger than rabbits to reduce the risk to these non-target animals. Env i ronm ent al fate Pindone is likely to dissipate slowly in baits, particularly under wet conditions. Small amounts may be leached from baits under wet conditions, but any residues entering soil would be expected to be degraded by bacteria in 5–6 weeks in moist sheltered areas and leaves no harmful residues. Pindone will breakdown under the ultra-violet light of sunlight in 2–3 weeks if left exposed. Most of the pindone eaten by rabbits should be absorbed and metabolised within a few days. Based on the limited information available no significant or persistent contamination of the environment by both pindone formulations is expected from rabbit control operations using pindone baits. Pindone baits are likely to pose minimal threat to aquatic organisms. Is p i n done hum ane? After ingestion of anticoagulants, there is usually a lag period of 3–5 days before the onset of clinical signs. This delayed onset reflects the time required to deplete existing stores of vitamin K and blood clotting factors. Initial signs of poisoning are listlessness and anorexia followed by manifestations of haemorrhage including anaemia, laboured breathing, pale mucous membranes and weakness. Bleeding may be visible around the nose, mouth, eyes and anus and animals may pass bloody faeces. Swollen tender joints are common as a result of bleeding into the confined joint space. Discomfort and pain from haemorrhages in internal organs, muscles and joints typically lasts for several days before death. The time to death is around 10 to 14 days after the initial dose. POISONS & FUMIGANTS 81 M inim is ing t he r is k to n o n - targ et an imals Poisoning of non-target species can occur either directly by eating the carrot, oat or pellet baits intended for rabbits or through the tissues from a dead or dying poisoned animal. Although information on the toxicity and non-target impacts of pindone is limited, it is thought to be moderately toxic to a range of species. Secondary poisoning may occur in species which feed on poisoned rabbits and carcasses such as quolls and raptors. Rabbits dying from pindone poisoning can become lethargic and less aware of their surroundings. This can predispose these animals to predation which can in turn place predators at greater risk from secondary poisoning. Non-target species that accidentally receive a high enough dose of pindone may exhibit the same clinical signs as rabbits. Pindone is slow acting, so accidental poisoning of stock or companion animals may be treated with vitamin K1 (phytomenadione) to be administered by a veterinarian. It is usual to treat an affected animal with vitamin K1 for at least one week after an initial loading dose. If bleeding is severe, whole blood or plasma can be given to replace clotting factors and red blood cells. To minimise the potential for toxic baits to be lethal to non-target animals, the following baiting strategies are recommended: Proceeding with unpoisoned bait – allows an assessment of what animals are eating the bait. Bait type – use of surface coated rather than vacuum impregnated oat baits may reduce exposure of grain eating birds to the toxin. These birds may eat the kernel and discard the poisoned husk. Colouring of baits – pindone baits are dyed green colour to reduce exposure to birds. Use of bait stations – bait may be placed under mesh canopies where it is accessible to rabbits but access by non-target species such as kangaroos and wallabies is restricted. Placement of bait – poisoned bait may be broadcast instead of concentrated in a trail, to decrease the consumption of poisoned bait by non-target species. Poisoned bait should be placed in the prime feeding areas of rabbits. Timing of baiting – rabbits mostly feed at night, therefore bait laid in the evening will be mostly consumed overnight before non-target species such as birds will have access. However, nocturnal mammals will be at risk when bait is laid in the evening. Collection of uneaten baits and rabbit carcasses – any uneaten bait and poisoned rabbit carcasses are collected and either destroyed by incineration or buried. Note: Where there is a significant risk of exposure to non-target animals, measures must be taken to reduce this risk, or bait should not be laid. Aut hor is at ion to obtain , sto re an d u se p in d o n e concent rate and s upp ly p in d o n e b ait Only an ACO and registered CPO may use pindone concentrate to prepare fresh pindone bait material as described in the Access to Restricted chemical products section, page 55.

If no landfill is available, bury the containers below 500 mm of soil in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and tree roots. Empty containers should not be burnt. All bait that is uneaten 4 days after bait consumption ceases should be collected and destroyed either by incineration or burying at a depth of 500 mm of soil. Alternatively, trails of poisoned carrot or oat bait can be covered with sufficient soil to prevent non-targets from gaining access. Carcasses of poisoned rabbits should be collected for a minimum of 12 days after the last poison feed. They should be destroyed by incineration or buried at a minimum depth of 500 mm of soil in a disposal pit. Was hing and cleaning proced u res Pindone sodium is soluble in water so all equipment should be thoroughly rinsed with water and allowed to drain. When washing down in the field, waste water, bait and other waste should be buried in a pit or collected in a container marked pindone and returned to the pesticide facility for disposal.

B R O M A D I O LO N E I nt roduc t ion Bromadiolone is a second generation anticoagulant poison used to control mice around sheds, silos and crop perimeters. Second generation anticoagulants are quick acting poisons and, unlike with the first generation anticoagulants such as pindone, require only a single dose to be effective. Second generation anticoagulants such as bromadiolone are also effective against mice that have developed a resistance to first generation anticoagulants. Phys ical and chem ical p ro p er ties Bromadiolone liquid concentrate is available in 1 L, 5 L or 20 L drum sizes containing a blue, slightly viscous liquid emulsion containing 1 g/L of the active constituent bromadiolone. The concentrate is mixed with grain. VERTEBRATE PEST CONTROL MANUAL 86 POISONS & FUMIGANTS M o d e of ac t ion Bromadiolone interferes with vitamin K cycle, disrupting the clotting ability of blood. The potency of bromadiolone is about 10 times that of other anticoagulants. Eventually, bromadiolone causes death due to internal haemorrhage. Time between ingestion and death appear to be from one to 14 or more days. M i n i mis ing t he r is k to no n - targ et an imals Non-target species must consume comparatively large amounts of bait with a concentration of 0.05% active ingredient, to reach a toxic or lethal dose. To minimise risk to non-target species, all users should do a risk assessment of the impact of baiting on non-target species and comply with the pesticide label and APVMA minor use permit number – PER11331, expiring on 30 June 2016. The risk assessment should consider: • identifying non target species likely to be impacted • applying bait within the recommended restrictions such as distances from tree lines to minimise harm to grain eating birds • identifying correct bait type, untreated or unclean grain • providing all the information necessary to make judgements on when and how to bait • identifying gaps in training for all users.

POISONS & FUMIGANTS 89 CO U M AT E T R A LY L R O D E N T B A I T – R AC U M I N 8® I nt roduc t ion Racumin 8 ® has coumatetyralyl as the active constituent. Coumatetralyl is a first generation anticoagulant poison similar to warfarin. It is used to control rats and mice around farm buildings. Being a first generation anticoagulant, multiple doses need to be consumed to receive a lethal dose as a single dose exposure may not produce toxic symptoms as the compound is quite rapidly metabolised. Phys ical and chem ical p ro p er ties Racumin 8® is a violet coloured odourless powder concentrate containing 8 g/kg of the active constituent coumatetralyl usually supplied in 10 kg tubs. The concentrate is mixed with grain and canola oil to attract mice and encourage ingestion. M ode of ac t ion Coumatetralyl reduces the clotting ability of blood by disrupting the vitamin K cycle. Animals die from internal haemorrhaging within 3 to 8 days after the initial dose. Poison bait must be available over several days to ensure rodents receive a lethal dose. Few rodent carcasses are seen after poisoning because most rodents die in or under the harbour being used such as holes and hay bales but rodents may be active in the treated area for many days after eating the poisoned bait. Where possible carcasses should be collected and disposed of according to the pesticide label. Environm ent al fate Coumatetralyl has a similar environmental fate to that of pindone and other anticoagulant poisons, and is not expected to constitute a significant health hazard. Secondary poisoning through the consumption of rats and mice killed with coumatetralyl may occur in dogs, cats and carnivorous birds such as owls. M inim is ing t he r is k to n o n - targ et an imals Non-target organisms are potentially at risk from direct consumption of baits and through eating poisoned rodents. To reach the toxic or lethal dose, the non-target species must consume bait over a sustained period. A person taking possession and applying coumatetralyl rodent baits must be given a copy of the pesticide label and the APVMA minor use permit number – PER12845, expiring on 30 June 2016, read it and follow all directions.

It is commonly available to the general public in retail stores in the form of pellets or wax blocks. As a second generation anticoagulant, brodifacoum usually requires only a single feed to deliver a lethal effect. APVMA minor use permits (https://portal.apvma.gov.au/permits) are utilised to enable use of brodifacoum in the form of bait for bait stations or to be distributed with spreading equipment, on islands of the coast of NSW. R A B B I T H A E M O R R H AG I C D I S E A S E ( R H D ) I nt ro duc t ion Rabbit haemorrhagic disease (RHD), is an acute, highly contagious viral disease which only affects the European wild rabbits Oryctolagus cuniculus and their domestic relatives. The virus was first reported in China in 1984 and spread across China and into Europe. Subsequently it has also occurred in northern Africa, North America and on islands in the Indian Ocean. To date it has been reported in over 40 countries world-wide. POISONS & FUMIGANTS 93 RHD was first registered as an injection in Australia in 1996. It is now registered for use as a bait on carrot and oats. As RHD is now prevalent in the majority of wild Australian rabbit populations and high levels of immunity to the virus is expected to occur periodically. Release of the virus in a population of rabbits with high immunity may have minimal impact. M ode of ac t ion In most adult rabbits the disease progresses rapidly from fever and lethargy to sudden death within 48–72 hours of infection. The virus causes acute liver damage from blood clotting. Death occurs due to obstruction of blood supply in vital organs and internal haemorrhages. Biological proper t ie s The virus comprises an RNA molecule, enclosed within a protein coating. Like all viruses, it reproduces only within the living cells of the European wild rabbit. The virus is manufactured from laboratory rabbits that have been inoculated with a Czechoslovakian isolate of the virus, designated strain CAPM V-351. Further research on other strains is continuing to improve efficacy. Effec t ivenes s Rabbits infected with the virus develop the disease within one to three days. The virus is lethal in more than 75% of infected susceptible rabbits. Rabbits younger than 12 weeks that become infected with the virus are less likely to die because they have maternal antibodies that protect the young rabbit from disease. Young rabbits that survive initial infection become immune adults. Since its release in 1996, natural outbreaks of the RHD continue to have variable effects on rabbit populations. This variability is due to many factors one of which is that natural outbreaks do not always coincide with times when rabbit populations are most susceptible to the disease. Some populations of rabbits in high rainfall areas have demonstrated a partial immunity to the virus because they carry a benign strain of the disease. For that reason the impact of RHD has generally been greatest in the arid and semi-arid zone. It is predictable that RHD will evolve to a point where the virus becomes less effective. This selection pressure could occur most rapidly in the arid zone of Australia where the death rate is higher prompting an increase in natural selection for resistant rabbits. The timing of RHD spread is important. If an outbreak occurs in early spring, it is more likely to immunise young rabbits and the disease may be less effective. When outbreaks occur in autumn or winter, when spring and summer born rabbits have grown into adults, the effectiveness of RHD is likely to be greater. Therefore the optimum time to release RHD virus into a susceptible rabbit population is late summer and autumn. VERTEBRATE PEST CONTROL MANUAL 94 POISONS & FUMIGANTS Is R HD hum ane? In most rabbits, death from RHD is very quick. Some animals show no signs of illness prior to death whilst others will have elevated temperature, anorexia, apathy, dullness, prostration and reddened eyes. Rapid respiration, bloody nasal discharge, convulsions, paralysis and squealing may be seen in the later stages. However, five to 10% of rabbits may show signs of chronic disease. These animals may have jaundice, weight loss and lethargy for up to 2 weeks before dying. M i n i mis ing t he r is k to no n - targ et an imals RHDV has not been known to infect or cause death to any other animal species in the wild apart from rabbits. All rabbits in Australia are derived from the European wild rabbit and are therefore potentially susceptible to infection. Farmed and pet rabbits should be vaccinated against RHD. Vaccinations are available from veterinary practitioners. Sto rage of RH D vir us s us pen sio n RHD virus suspension should be stored at –5°C. Once opened, the entire contents of vials must be used within 48 hours. Opened vials must be stored in a refrigerator, 4°C and MUST NOT BE FROZEN. Pre p arat ion of bait s inoculated with R HDV su spen sio n Safety directions Humans cannot contract RHD virus, however allergic reactions may affect some users. When mixing the virus on oats or carrots, it is advisable to wear impermeable gloves and a full face shield to reduce the opportunity for the foreign protein to contact skin, eyes, or mucous membranes. Preparation of baits Instructions for the preparation of RHD virus treated baits are provided on the product label. Only carrots or oats may be treated with the RHD virus suspension. One 10mL vial of RHD virus suspension diluted in 90 mL of sterile, distilled water is sufficient to treat 6 kg of oats or 15 kg of chopped carrots. Oats should be intact oat grain with husks attached. Carrots should be of good quality and freshly diced. The treated bait should be mixed in an enclosed bait mixer, that meets the standard requirement for 1080 bait mixing. The appropriate quantity of feed material is added to the mixer. The viral solution is added to the mixer, preferably through spray nozzles inside the drum. The bait and viral solution should be evenly mixed. The bait is then delivered directly into plastic bags, labelled with Rabbit Haemorrhagic Disease Virus Suspension which meet the specifications outlined in the APVMA permit number 9305 (no expiry date). Baits must be used within 24 hours of inoculation. POISONS & FUMIGANTS 95 D is pos al of vials and u n u sed b aits Used vials should be soaked in 0.5% sodium hypochlorite, or 1 in 20 dilution of household bleach containing 10% sodium hypochlorite and water and buried in a local authority landfill or buried below 500 mm of soil in a disposal pit specifically marked and set up for this purpose. Empty vial containers and products should not be burnt. Unused baits and bags must be disposed of by deep burial. Was hing and cleanin g p ro ced u res Equipment used to prepare the bait should be decontaminated and cleaned at the completion of bait preparation each day by rinsing with 0.5% sodium hypochlorite. Following this, rinse the bait mixer and utensils with water and allow to dry. Supplying bait s inoc u lated with R HD viru s su spen sio n ACOs may only supply baits inoculated with RHD virus to people who meet the criteria in the current Pesticide Control (Rabbit Haemorrhagic Disease) Order (RHDV PCO). A person taking possession of baits inoculated RHD virus must be given a copy of the current RHDV PCO and Part B of the RHD Virus Suspension Label. Applying baits inoculated with RHD virus suspension Persons applying bait materials inoculated with RHDV must do so in accordance with the current RHDV PCO and Part B of the RHDV Suspension Label. G eneral res t r ic t ions Restrictions include: • treated baits may only be administered to wild rabbits • rabbits visibly affected by myxomatosis should not be baited • baiting of rabbits older than 12 weeks is recommended • if the existence of a critical native population is suspected in the area of baiting, advice should be sought from State or Territory conservation agencies so that appropriate predator control measures can be implemented if necessary. Free feeding Rabbits should be free fed according to the label instructions. Free feeding should occur at least twice for carrots and 3 times for oats. Treated baits should be applied at a rate of 10% of the rate applied in the final night of free feeding. Fir s t Aid – s pecific re co mmen d atio n s fo r R HD viru s Thoroughly wash exposed skin with soapy water after preparing bait feed.

DO NOT transport fumigants in the cabin of a vehicle. All fumigants must be stored in well-ventilated areas and never opened in an enclosed space. Where possible, fumigants should be stored adjacent to a vent or metal grill that opens to the outside and the storage facility should be fitted with roof ventilators. Ph o sphine Introduction The main diffuse or static fumigant used in NSW is phosphine gas. Poisoning occurs by inhalation, although swallowing a tablet is lethal. The gas is not readily absorbed through the skin. There are a number of registered phosphine tablet products available. Search the APVMA Pubcris database to see what products are currently available http://portal.apvma. gov.au/pubcris Mode of action Phosphine is a systemic poison which depresses the central nervous system and respiratory function. It is highly toxic to humans; therefore operators performing warren fumigation must take adequate precautions to safeguard against accidental exposure. Time to death can be highly variable depending on the concentration of gas in the burrow. For example, at concentrations of 400 ppm phosphine can kill rabbits in 30 minutes whereas at 25 ppm death will take 4 hours. The time taken to reach high concentrations throughout the warren largely depends on the amount of moisture in the soil and air, or on the tablets. In low humidity, complete release of phosphine gas from the tablets may take hours or even days. Higher humidity will cause a rapid rate of diffusion and therefore result in higher concentrations of gas so that the rabbit will be exposed to a lethal dose in a shorter time and will have less chance to dig out of the burrow. Physical and chemical properties Phosphine is a colourless gas, about 20% heavier than air, with a slight garlic odour. Phosphine gas is generated when aluminium phosphide tablets are exposed to moisture in the air. It remains gaseous at all normal temperatures and spreads quickly. The gas can react with copper, copper compounds, silver and gold at high temperatures. Tablets weigh 3 g and begin to emit phosphine immediately on exposure to moisture in the air. Complete decomposition takes about 48 to 72 hours depending on the humidity. Tablets come in tubes and packs with varying numbers ranging from 30 to 100 tablets. Fumigation tablets contain 560 to 570 g/kg of aluminium phosphide which produces 330 g/kg phosphine gas. Each 3 g tablet releases 1 g of phosphine gas when exposed to moisture in the air or soil. Sensitivity and susceptibility to phosphine gas Phosphine is not species specific and is highly toxic to humans and animals. Animal experiments have revealed that rabbits exposed to 70 mg phosphine/m3 (50 ppm) for 10 minutes do not develop any symptoms but exposure to 140 mg/m3 (100 ppm) is fatal in 2.5 to 3 hours, and 700 mg/m3 (500 ppm) is fatal 25 to 30 minutes. POISONS & FUMIGANTS 97 For humans, the short term exposure limit is 0.3 ppm and concentrations of 50 ppm are immediately dangerous to health. Environmental fate Aluminium phosphide will break down spontaneously in the presence of water to form a gaseous product, and so it is non-persistent and non-mobile in the soil environment, and poses no risk to groundwater. It is highly unlikely that aluminium phosphide or phosphine will be found in surface waters. Phosphine decomposes in the atmosphere within 5–28 hours. It should be noted that phosphine gas, when liberated by contact with moisture, can be toxic to fish and aquatic organisms, and every care should be taken to avoid contamination of aquatic environments. Is phosphine humane? Fumigation is considered to be less humane than poisoning with 1080. Therefore, it is desirable to fumigate only after a poisoning program when the density of rabbits is low. This minimises the number of rabbits exposed to fumigation. Phosphine is currently the preferred toxin for diffusion fumigation until more humane methods are developed. Chloropicrin is considered to be highly inhumane and its use is not recommended. The precise nature and extent of suffering of rabbits after inhalation of phosphine is unknown. Symptoms of phosphine toxicity in humans often include nausea, abdominal pain, headache and convulsions followed by coma. Failure to reach lethal levels of phosphine in some parts of the warren because of inadequate diffusion will result in ineffective killing but will not necessarily cause longterm suffering. Studies in other species (i.e. cats, guinea pigs and brown rats) have produced no evidence to suggest that exposure to sub-lethal levels of phosphine gas causes sub-acute or chronic poisoning. Therefore, rabbits that escape from fumigated warrens or those that are exposed to sub-lethal concentrations in deeper parts of the warren may only experience transient illness, not permanent debilitation. Minimising the risk to non-target animals Fumigation of rabbit warrens is one of the most target-specific means of rabbit destruction and will have little impact on non-target species if used correctly. Fumigation must only be used in active, occupied warrens. If a warren appears to be empty or possibly occupied by a non-target species (e.g. wombats, dingoes, lizards, snakes), fumigation must not be performed. There appears to be no significant risk of secondary poisoning if carcasses of gassed animals are consumed by non-target predatory or scavenger species. If using dogs to work an area prior to warren fumigation, the following should be observed: • Dog handlers must be experienced and the dogs well trained. The dogs must be easily controlled by a whistle or call and obey the handlers’ commands. • Dogs must not chase or attack non-target animals including livestock. • Dogs are not allowed access to treated warrens. To ensure that dogs are not exposed to phosphine gas or allowed access to treated warrens, handlers must ensure that dogs are well restrained during and after fumigation. VERTEBRATE PEST CONTROL MANUAL 98 POISONS & FUMIGANTS Storage Aluminium phosphide tablets should be stored: • in a locked place away from children, animals, food, feedstuffs, seed and fertilisers • in the closed, original container in a dry, cool, well-ventilated area out of direct sunlight • away from water and liquids which will cause immediate release of phosphine gas • at least 5 m away from Schedule 6 and 7 poisons such as 1080, Larvacide® (chloropicrin) and pindone. Store in a locked, waterproof metal cabinet clearly marked aluminium phosphide. Do not store aluminium phosphide in a small gas-proof enclosure. Us i n g alum inium phos ph id e tablets Health and safety • Operators must strictly follow the directions on the approved label when using and storing aluminium phosphide tablets. They must not be used for any other purpose than the destruction of rabbits in active warrens. • Fumigation must always be carried out by two trained persons and must not be carried out in wet conditions when it is likely that the tablets will become wet before insertion in the burrows. • Phosphine is highly toxic to humans and can kill if the tablets are swallowed or the liberated gas is inhaled. Avoid contacting the skin with aluminium phosphide or breathing phosphine gas. • If poisoning occurs seek immediate medical attention andcontact the Poisons Information Centre, Phone 131 126. • Symptoms of overexposure to phosphine gas include headache, dizziness, nausea, and difficulty breathing. Severe exposure may damage liver, kidneys, lungs, and nervous and circulatory systems, and may cause death. • Appropriate PPE should be worn when using fumigant. This includes: – overalls – elbow length PVC or rubber gloves – full-face respirator with combined dust and gas cartridge (canister) or breathing apparatus with air supply. • After use and before eating drinking or smoking, wash hands, arms and face with soap and water. • After use, wash contaminated clothing and gloves. • For further information refer to the SDS available from the supplier. Eye-wash stations or baths should be available where aluminium phosphide is being used. Deluge showers or eye wash stations should be provided where aluminium phosphide is being stored. Refer Biology, ecology and management of vertebrate pests in NSW – Rabbits chapter for information on how to carry out phosphine fumigation. POISONS & FUMIGANTS 99 Fir s t Aid – s pecific re co mmen d atio n s fo r alu min iu m phos phide If poisoning occurs, go to a doctor or hospital quickly. If swallowed, rinse mouth thoroughly with water and contact the Poisons Information Centre on 131 126. Urgent hospital treatment is likely to be needed. Do NOT give mouth to mouth resuscitation if this product has been swallowed. If a patient has swallowed aluminium phosphide they may begin emitting toxic phosphine gas. First aid and medical staff should take precautions against exposure to phosphine emitted by such a patient. If irritation does occur flush the contaminated eye(s) with lukewarm, gently flowing water for 5 minutes or until the product is removed, while holding the eyelid(s) open. Obtain medical advice immediately. If irritation occurs wash gently and thoroughly with water for 5 minutes or until chemical is removed. If irritation persists, repeat flushing and obtain medical advice. If any unusual symptoms become evident, or if in doubt, contact the Poisons Information Centre on 131 126 or a doctor. If inhalation occurs seek medical assistance immediately. Remove source of contamination and move the patient to fresh air as soon as possible. DO NOT administer mouth-to-mouth resuscitation – use other forms of resuscitation. DO NOT allow victim to move about unnecessarily. Symptoms of pulmonary oedema can be delayed up to 48 hours after exposure. Chloropicr in Introduction Chloropicrin is registered for use as a pesticide in Australia and is mainly used as a fumigant to control pest species in soil, however it is also used to control vertebrates such as rabbits. Chloropicrin is the active ingredient of the liquid available in 500 mL bottles as Rural Larvacide Rabbit Fumigant®. Chloropicrin can only be used through a pressure fumigator if the operator has had appropriate training in additional to chemical accreditation at AQF3 level (ref: Work Health and Safety 2011, Exemption Order No. 008/13). A Supervisor who supervises and train others in using chloropicrin and/or aluminium phosphide must have a chemical users training at AQF4 level training in addition to vertebrate pesticides / fumigation training. WorkCover currently licence fumigators that use chloropicrin but there are currently exemptions that apply to some agricultural use. WorkCover has issued an exemption order which applies to LLS staff which is due to expire in 20 June 2015. Mode of action Poisoning occurs by inhalation. Chloropicrin gas in very small concentrations is highly irritating to the lungs and eyes. Lethal chloropicrin toxicosis from fumigation causes death from pulmonary oedema, bronchopneumonia, emphysema or bronchiolitis obliterans. The toxicity of chloropicrin is primarily influenced by effects on the small and medium bronchi and the speed at which death occurs depends upon the concentration and period of exposure. In liquid form it will cause burns and must be immediately washed off affected skin or eyes. Remove any contaminated clothing immediately. VERTEBRATE PEST CONTROL MANUAL 100 POISONS & FUMIGANTS Physical and chemical properties Chloropicrin was first synthesised from picric acid (2,4,6-trinitrophenol) and calcium hypochlorite in 1848. It is a powerful lachrymator (‘tearing agent’) with a strong, sharp and highly irritating odour. It is variously described as a clear, colourless-to-light-green or colourless-to-faint-yellow oily liquid. Chloropicrin was used for chemical warfare in World War I as a tear gas. It works as a fumigant by evaporation of the liquid, but the gas does not spread as quickly as phosphine, being five and a half times as dense as air. Chloropicrin is non-corrosive to copper and brass but attacks most other metals. Sensitivity and susceptibility to chloropicrin For humans, the time weighted average (TWA or working week exposure limit) for chloropicrin is only 0.1 ppm. Chronic exposure to chloropicrin is not a risk as the gas is so irritating at low doses, being a very strong tear gas, that it would be impossible to remain long enough for chronic toxicity to occur. Environmental fate Chloropicrin degrades to carbon dioxide in soils with a half-life between 8 hours and 4.5 days. Chloropicrin moves rapidly in soils and can diffuse to 1 m in sandy soil. It is unlikely to move rapidly in water due to its low solubility. Chloropicrin will volatilise quickly in water and from soils. It is not expected to absorb to soil particles. In should be noted that chloropicrin is toxic to fish and every care should be taken not to contaminate aquatic environments. Is chloropicrin humane? Chloropicrin is considered to be highly inhumane and its use is not recommended. It causes intense irritation of the respiratory tract and profuse watering of the eyes for a considerable period before death. Minimising risk to non-target animals Refer to Minimising risk to non-target animals under phosphine fumigation page 98. Sto rage Chloropicrin should be stored: • in a locked place away from children, animals, food, feedstuffs, seed and fertilisers • in the closed, original container in a dry, cool, well-ventilated area out of direct sunlight • away from extreme heat and open flames Do not store near oxidising material or water. The area is adequately ventilated to prevent poisoning or a heavy gas concentration if there has been some form of leakage. Chloropicrin must be stored securely in a tray capable of holding at least 110% of the largest container or 25% of the total volume of liquid being stored, whichever is largest. POISONS & FUMIGANTS 101 Soda ash or lime should be stored to be used to neutralise any chloropicrin spillage that occurs. Keep approximately an equal amount of soda ash or lime and chloropicrin. That is, if there is usually about 50 L or chloropicrin in store then keep about 50 kg of soda ash or lime on hand. Us ing chloropicr in for pressu rised f u mig atio n Safety You must take extreme care when handling and using chloropicrin because it is extremely dangerous. Undiluted chloropicrin is highly toxic by inhalation, ingestion or direct contact with the skin or eyes. Inhalation exposure to very high levels, even briefly, can lead to pulmonary oedema, fluid accumulation and swelling of the lungs, unconsciousness and even death. When handling chloropicrin the handler must have adequate protective clothing. As chloropicrin is chemically inert and many canister-type respirators will not absorb the chemical only positive pressure breathable air type respirators should be used. Other equipment includes impermeable overalls, elbow-length impervious gloves and ensure the entire face particularly the eyes are covered and protected. Refer Biology, ecology and management of vertebrate pests in NSW – Rabbits chapter for further information. Fir s t aid – Specific re co mmen d atio n s fo r c h lo ro pic rin If there is any contact by any route (apart from very minor inhalation), contact the Poisons Information Centre or a doctor immediately. Do not wait for symptoms of poisoning. Operators should have a plentiful supply of soap and water for washing present when chloropicrin is being used. Eye wash baths should be available when chloropicrin is being used. Where practical, deluge showers should be provided when this product is being used. If no breathing difficulties give water to dilute (maximum 250 mL for adults; 125 mL for children). Obtain medical attention immediately. If in eyes, hold eyes open, flood with water for at least 15 minutes. Ensure irrigation under eyelids by occasionally lifting them. Do not try to remove contact lenses unless trained. See a doctor. If skin contact occurs, remove contaminated clothing and wash skin thoroughly with soap and running water (for at least 15 minutes). If safety shower is available, use it promptly. Seek urgent medical attention if skin blisters, or if it looks or feels unusual. Because of the toxicity of this product, speed may save a life. Remove from contaminated area. Apply artificial respiration if not breathing. If giving mouth-to-mouth resuscitation wash out patients mouth and lips – do not inhale patient’s expired air. If vapours or mists have been inhaled, and irritation, including a cough or difficulty breathing, or other unusual symptoms have developed, seek medical advice. Get to a hospital or doctor quickly. Monitor breathing for several hours after exposure. VERTEBRATE PEST CONTROL MANUAL 102 POISONS & FUMIGANTS Carbon m onox ide – DEN - CO - FUM E® Introduction Carbon monoxide fumigant cartridge known as DEN-CO-FUME® is the only fumigant registered for foxes and that may be used on fox natal dens. Carbon monoxide gas is very toxic and poisoning occurs via inhalation. The absorption and resulting symptoms are dependent on the concentration of carbon monoxide in the inspired air, the time of exposure and the state of activity of the person exposed. Mode of action When inhaled carbon monoxide combines with haemoglobin in red blood cells, with an affinity 250 times that of oxygen, to form carboxyhaemoglobin. This results in reduced oxygen-carrying capacity and altered delivery of oxygen to cells. Hypoxia, the reduction of oxygen supply to the tissues, eventually leads to unconsciousness and death. While exposure to very low levels of carbon monoxide may cause no symptoms or only slight headache and shortness of breath, longer exposure to higher concentrations of carbon monoxide will convert more than 50% of blood haemoglobin to carboxyhaemoglobin. Prolonged exposure to concentrations of carbon monoxide over 1000 ppm (0.1%) causes loss of consciousness, failure of the respiratory system followed by death from cardiac arrest.Death occurs without pain and while the animal is unconscious. Time to death depends on the final carbon monoxide concentration but is typically within minutes or a few hours at a concentration greater than 1%. Higher concentrations are achieved in smaller dens. Physical and chemical properties Carbon monoxide is a colourless and odourless gas. Carbon monoxide is formed when DENCO-O-FUME® cartridge is ignited by the lighted fuse. The subsequent smoke is poisonous if inhaled. The smoke is non-irritating. DEN-CO-FUME® cartridges weigh 240 g and contain 65% sodium nitrate and 35% charcoal. These cartridges are capable of producing concentrations of carbon monoxide up to 3% in a dead volume of 1000 litres (1 m3). Sensitivity and susceptibility to carbon monoxide Carbon monoxide is extremely hazardous to humans and is highly toxic to most mammals and difficult to detect. Species specificity is achieved from accurate identification of occupied fox natal dens. Effects may be rapid if exposed to high concentrations of carbon monoxide. Environment fate Carbon monoxide is biologically degradable and will not accumulate in soil or water. Is carbon monoxide humane? Fumigation of fox natal dens with carbon monoxide (CO) appears to be humane provided that high enough concentrations of CO can be introduced into the den to bring about rapid death. The depletion of oxygen leads to unconsciousness and death without pain or discernable discomfort. It is important that cubs are more than four weeks old to ensure they are fully susceptible to the effects of CO. POISONS & FUMIGANTS 103 Minimising the risk to non-target animals Fumigation of occupied fox natal dens is very target-specific and will have little impact on non-target species if used correctly. To minimise the risk to non-target species monitor the den to ensure other species are not using the den before fumigation is undertaken. Carbon monoxide storage Carbon monoxide fumigant cartridges are classified as Dangerous Goods Class 1.4G and must be stored and transported safely. WhenDEN-CO-FUME® cartridges are stored in bulk consider Dangerous Goods Storage related Regulatory requirements. It is flammable, so consider compatibility and separation issues. Store carbon monoxide fumigant cartridges in the closed, original container in a dry, cool, well ventilated area out of direct sunlight and away from other heat or ignition sources or oxidising agents. Us ing car bon m onoxid e f u mig ant c ar trid g es Health and safety Operators must strictly follow the directions on the DEN-CO-FUME® label and SDS when using and storing carbon monoxide fumigant cartridges. This product must not be used for any other purpose than the fumigation of active fox natal dens. Carbon monoxide is highly toxic to humans and can kill if the resulting smoke is inhaled. It is essential to have adequate fresh air available to the operators during use of cartridges. Do not inhale smoke. Appropriate personal protective equipment should be worn. This includes: • protective gloves • protective glasses • respiratory protective equipment is recommended although in the SDS it is stated as not necessary when fumigation is conducted in the open air. Manufacture’s recommended method of use: 1. Determine the location of active fox natal dens. 2. Before igniting, unwind the 50 cm fuse and open holes at the top of the cartridge around the inserted fuse. Using a broom handle or flexible hose establish that no animals are within 1.5 m of the entrance. 3. Place the cartridge, in the direction of the arrow, into the entrance of the active fox natal den. 4. Bend the fuse back along the cartridge so it can be lit. 5. Ignite the fuse, confirm that the cartridge has ignited and seal the entrance to the den with earth If smoke emerges from any other entrances attempt to seal these with earth also. 6. Do not disturb the den after fumigation. Rates of application When dens are in enlarged rabbit warrens with several entrances or of large volume it may be appropriate to use two cartridges. The total carbon monoxide concentration achieved with multiple cartridges is additive that is 2 cartridges produce up to 6% carbon monoxide.

Contact a doctor or Poisons Information Centre, Phone 131 126. Have the SDS or the product label with you. Contents are poisonous if swallowed and may irritate the eyes, nose and throat. Once the DENCO-O-FUME® cartridge is ignited it will burn vigorously until completely spent and is capable of causing severe burns to exposed skin and clothes. Swallowed: Seek medical attention. Eye: Flush thoroughly with copious amounts of running water. If symptoms persist, seek medical attention. Skin: Remove contaminated clothing. Wash skin thoroughly with soap and water. Inhaled: If headache or drowsiness occurs transfer victim from contaminated area to fresh air and give oxygen if available. If unconscious, give artificial respiration and get to a hospital or doctor quickly. S T R YC H N I N E I nt ro duc t ion Strychnine impregnated cloths may be used on rubber jawed traps for wild dog control when traps cannot be serviced daily. Trap-jaws are bound with strychnine-laced cloths to hasten death and prevent prolonged suffering. Use of strychnine is permitted under the APVMA permit. The current permit is PER12761 ‘For the use of strychnine impregnated cloths in soft catch spring traps for wild dogs in NSW’ which expires on 30 June 2014 (http://permits.apvma.gov.au/PER12761.PDF). Phys ical and chem ical pro per ties Strychnine hydrochloride is the hydrochloride of the alkaloid strychnine, which is obtained from the seeds of Strychnos nux-vomica L. and other species of Strychnos. In its solid form strychnine hydrochloride is described as colourless prismatic crystals or a white crystalline powder, with an intensely bitter taste. M o d e of ac t ion Once absorbed, strychnine enters the blood stream and acts on the central nervous system, affecting the transmission of nerve impulses which control muscle contraction. Strychnine also causes an increase in the levels of glutamic acid in the brain. This can lead to the skeletal muscles becoming hyper excitable causing simultaneous muscle contraction, convulsions and seizures which prevent respiration. Death generally results from suffocation or exhaustion. S e ns it ivit y and s us cept ibilit y to str yc h n in e Strychnine-sensitivity is fairly broad and it is therefore more difficult to achieve target specificity. Dogs are moderately susceptible to strychnine. Appendix B shows the susceptibility of different animals to strychnine. POISONS & FUMIGANTS 105 Environm ent al fate Strychnine shows little or no breakdown by exposure to light. Strychnine can be degraded in some soils as a result of microbial activity however; this degradation is generally very slow. Microbial degradation doesn’t appear to occur in some instances because the strychnine gets bound to soil particles, a factor that is influenced by the soil pH. Is s t r ychnine hum an e? Ingestion of strychnine will bring about a relatively quick, although painful and distressing, death rather than a prolonged death from exposure, dehydration and/or stress associated with the use of padded-jaw traps which cannot be inspected frequently. Strychnine is a fast acting poison that is highly toxic to most animals. Animals experience restlessness, nervousness, apprehension and stiffness with muscular twitching that progress to severe seizures. Violent muscular spasms extend the limbs and curve the neck upwards and backwards; the jaws fix and the eyes protrude. Respiration may stop momentarily during seizures. Frequency of seizures increases and death eventually occurs 1 to 2 hours after ingestion due to exhaustion or asphyxiation (respiratory failure) during a seizure. Poisoned animals remain fully conscious until near death. The use of strychnine should therefore only be used when absolutely necessary for leg-hold traps that cannot be checked on a daily basis. M inim is ing t he r is k to n o n - targ et an imals Species other than canids may not gnaw at the jaws of the trap and so will be unlikely to be poisoned by contact with strychnine cloths. However it should be noted that traps are not target specific, so a wide range of non-target species may be caught. These can include birds, kangaroos, wallabies, rabbits, hares, goannas, possums and sheep. If there is a high risk of trapping non-target animals, traps should not be set. Storage and dis pos al • All strychnine powder, strychnine cloths and mixing equipment must be stored in a locked metal cabinet and only the ACO who uses it is permitted access. • Containers that have held cloths are not to be used for any other purpose and must be disposed of by deep burial. • Used cloths must be recovered and disposed of by deep burial. • Do not contaminate dams, rivers, streams, waterways or drains with the cloths or used containers. P R E PA R AT I O N O F S T R YC H N I N E I M P R E G N AT E D C LOT H S H ealt h and s afet y Strychnine is highly toxic to humans and should be handled with care. • Operators using strychnine must strictly follow the directions on the product label when preparing for use, using, storing or disposing of the pesticide. • Appropriate personal protective equipment, including elbow length PVC or nitrile gloves and a face mask or safety glasses, must be worn when preparing and handling poison and cloths. VERTEBRATE PEST CONTROL MANUAL 106 POISONS & FUMIGANTS • After use and before eating drinking or smoking, wash hands, arms and face with soap and water. Wash contaminated clothing and gloves. For further information on strychnine refer to the Safety Data Sheet, available from the supplier. Pro cedure for t he us e of str yc h n in e c lo th s o n wild d o g t ra p s in N SW NSW DPI recommends that padded jaw traps are checked daily to maximise the effectiveness of programs, minimise stress of trapped animals and enable the safe release of non target species. The use of strychnine on padded jaw traps is not a preferred option for wild dog control in NSW. A ‘strychnine cloth’ is a strip of fabric wrapped around the jaw of a padded jaw trap to which strychnine is applied. When caught, the wild dog must chew on the cloth to receive a fatal dose of poison. There are occasions when, for whatever reason, the dog does not chew the cloth, the cloth or wire attaching it unravels in the initial encounter with the trap or the strychnine is leached out with excessive rain and the poison is dispersed. For these reasons checking traps should be a daily requirement of any trapper. A risk assessment must be undertaken and recorded to determine if the use of strychnine cloths on padded jaw traps is a suitable and safe strategy to control wild dogs in a particular location. Ap p lying s t r ychnine to t he p ad d ed jaw trap Check traps for wear and repair if necessary. Wearing the correct PPE and using either a trap setting device or sufficient manual force, open the jaws and wedge open or clamp the springs to prevent the trap closing. Position the trap so there is easy access to the jaw normally held under the dog or tongue of the trap. This jaw will be wrapped in the cloth. Place strychnine pad on one jaw only (as illustrated on page 108). Cut hessian or similar coarse fabric into strips about 6.5 cm wide and 30 cm long for Lanes size traps or 20 cm long for Victor or similar sized traps and a 30 cm piece of soft wire. Wrap the cloth strips in a bandaging pattern around one section of the held jaw, overlap the cloth by 50% as it wraps around the jaw. Make 2 full wraps of the jaw. Along the cloth place 2.5 g of strychnine crystals on, what is normally, the top surface of the jaw when the trap is closed. Continue wrapping the jaw with the remaining length of cloth, making sure the area treated with strychnine is well covered. Using a piece of soft wire, fasten the cloth pad at one end and starting on one side of the cloth pad, firmly wrap the wire several times around the jaw and pad. Make sure the wire can not cause injury to a trapped animal. POISONS & FUMIGANTS 107 Twist the wire underneath the jaw and cut off the excess. Repeat for the other end of the cloth pad, ensuring that the central 4 cm of the cloth pad is free of wire. Ensure the wire is firmly attached and will not be ripped away before the dog chews on the soft wrapping, otherwise, the wrapping may be torn away and the wild dog may not ingest any poison. As a precaution against strychnine loss through the cloth, some trappers may bind the finished strychnine pad with a thin wrap of electrical insulation tape. Remove clamps, set and place the trap. Figure 10. Strychnine cloth wrapping the jaw of a Lanes trap and covered with electrical tape. Occupat ional H ealt h an d S afet y Strychnine is a white crystalline substance sometimes dyed pink with a bitter taste and slight odour. It is available as an alkaloid formulation that is almost entirely insoluble in water and very stable unless in acid soils where salt formation may increase solubility in water and allow leaching. Strychnine is highly toxic and can be rapidly absorbed through the mucous membranes of the mouth, stomach and small intestines. Once absorbed, strychnine enters the blood stream and acts on the central nervous system, affecting the transmission of nerve impulses which control muscle contraction. Fortunately, the kidney and liver work to eliminate the poison from the body and if a sub-lethal dose is taken, this inhibition is reversible. Strychnine causes an increase in the levels of glutamic acid in the brain and this leads to the skeletal muscles becoming hyper excitable causing simultaneous muscle contraction, convulsions and seizures which prevent respiration. Death generally results from suffocation or exhaustion. Strychnine can enter the body through inhalation, ingestion and broken skin. VERTEBRATE PEST CONTROL MANUAL 108 POISONS & FUMIGANTS M i n i mum PPE • Chemically impervious gloves, overalls buttoned to the wrist and boots and washable hat • Chemical splash goggles or face shield • Dust mask appropriate to inhalation risk with Class P1 particulate respirator or full face class P3 particulate respirator in high dust levels.

Remove any contaminated clothing from the patient. Wash any effected skin thoroughly through free flowing clean water. Do not induce vomiting. NOTHING should be administered to the patient by mouth. Place the patient into the recovery position to maintain their airway. If the patient stops breathing only administer resuscitation if sure that there is no risk to the rescuer ingesting the poison from the patient through mouth-to-mouth contact. A suitable barrier mask should be used if applying resuscitation. Be aware that the patient may have convulsions. Reassure the patient and keep them calm. If possible keep the patient in a quiet, dark place because they may be highly sensitive to noise and light. Wait for medical staff to arrive or if this is not possible take patient to doctor or hospital as soon as possible Make sure the strychnine product container, label and Safety Data Sheet (SDS) is available to medical staff. Sto rage Strychnine products must be stored in their original packaging in a locked metal container inside a locked bait preparation room except when they are required for immediate use. Strychnine products must always be kept in areas inaccessible to the children, animals, feedstuffs and the general public. All storage areas must comply with the Dangerous Goods Regulations for storage safety, security and warning signs. Safety Data Sheets (SDS) are required to be kept with all poisons stored. POISONS & FUMIGANTS 109 Trans por t Strychnine products and padded jaw traps with strychnine pads must be transported in a locked metal container firmly attached to a secured part of the vehicle and outside the cabin. Strychnine must never be transported with foodstuffs. Vehicles carrying poison must not be left unattended. Domestic animals must be segregated from the poison. Placing the strychnine container in a small locked toolbox inside an anchored and locked metal toolbox would be ideal for transportation. D is pos al of carcas s e s Dispose of poisoned carcasses by deep burial at least 500 mm deep and cover with soil. Prior to reuse remove damaged fabric wrapping from wild dog traps and dispose of by deep burial at least 500 mm deep and cover with soil. Do not store traps with fabric attached unless intended for immediate use and dispose of all strychnine impregnated fabric after 3 months. O utcom es of t rapping p ro grams • Humane and successful use of traps requires training and experience. The experience of the trapper using their domestic dogs to locate where wild dogs have urinated or marked is an essential part of a wild dog trapping program.

RISK DESCRIPTION OF HAZARD OR RISK LEVEL RECOMMENDED CONTROL MEASURES NEW RISK LEVEL DETAIL HOW CONTROL MEASURES WILL BE IMPLEMENTED AND ANY ADDITIONAL CONTROLS APPENDIX D – FIRST AID FOR WORKING DOGS AND OT H E R D O M E S T I C A N I M A L S Although this advice is primarily for working dogs poisoned by 1080, the treatment for all domestic animals is the same. This advice is also applicable to poisoning by pindone, but the veterinary treatment will differ with the type of poison. Reference: First Aid – 1080 and your dog (2004) Australian Wool Innovation Limited. What are the risks of poisoning working dogs? Wherever 1080 baiting is taking place, there is always a risk of accidental poisoning. Dogs may suffer accidental poisoning by eating baits, picking up baits that have been moved or relocated by other animals such as foxes, or eating dead animals that have been poisoned by 1080 baits. Accidental poisoning can occur in the paddock or area being treated or in areas adjacent to the baited paddock, particularly if an animal or bird has moved or vomited up some 1080 bait. How do I know my dog has been poisoned? Dogs seen eating bait material or suspected of picking up bait material should be taken to a veterinarian as quickly as possible. The time it takes for 1080 to work may be as little as 30 minutes to 2 hours before symptoms occur, depending on the dose. It is best to take action immediately rather than wait for the symptoms to appear. Quite often, once symptoms are evident it may be too late to save the animal. G et to a vet as ap Signs to watch for are: •anxiety • frenzied behaviour such as running or howling • hypersensitivity to sound or light • failure to respond to owner •vomiting • urinating and defecating inappropriately. And eventually: • convulsions, seizures and fitting • difficulty breathing • respiratory failure •coma •death. Inducing vomiting Extreme care should be taken when inducing vomiting, as the dog may react violently and expose toxic vomit, which can cause secondary poisoning of other domestic animals. VERTEBRATE PEST CONTROL MANUAL 118 POISONS & FUMIGANTS You should induce vomiting when: • you have seen your dog eat a bait or a poisoned carcass • there is a likely delay before veterinary assistance is available. Just because the dog has vomited does not mean all the poison is out of the stomach. Still seek veterinary attention. What can I use? • table salt, 1 to 3 tablespoons orally • salty water • dilute mustard and water. When using 1080 it is advisable to have a small plastic drink bottle with 30 to 50 g of salt and 250 mL water handy at all times. Ensure no other animal has access to the vomit, as they will be poisoned as well. What else can I do? • Call your local veterinary clinic and advise you are bringing in the animal. • Wrap the dog in a blanket or put in a box to restrict movement and prevent it from injuring itself. • If the dog is convulsing or fitting, keep your fingers clear of its mouth; it will not swallow its tongue. • Keeping the dog cool by spraying lightly with water or giving a good flow of air may help.
