CONSERVATION & HABITAT MANAGEMENT PLAN

Scope: This Conservation & Habitat Management Plan details protection and/or prevention measures to ensure that flora and fauna is managed appropriately during the construction phase. It defines mitigation measures to be implemented during relevant construction activities, a monitoring program that enables assessment of the impacts of construction activities on potentially affected areas, and contingency measures that may be implemented if required.

Objective:

To minimise any potential for impacts to the environment and/or natural habitats.

To conserve existing vegetation communities and native species present on site.

To protect any native fauna which may be identified on and/or adjacent to the site

To minimise the impact of any introduced fauna (i.e. vermin), or noxious flora (i.e. Weeds) or disease during construction.

Risks:

Native Vegetation

The project is situated at the Williamtown RAAF base, with components extending across a number of habitats.

The project footprint covers approximately 209 hectares, 81 hectares of which is largely cleared and modified grassland with minimal ecological value. The remaining naturally vegetated areas comprise an open forest / woodland and low woodland complex that are considered relatively high quality remnant natural bushland, both in terms of structure and the diversity of plant species. These areas provide food resources for a rich assemblage of nectivorous and insectivorous fauna including birds, mammals, reptiles and frogs. They also provide habitat (e.g. tree hollows) for a range of threatened fauna species known to occur in the area.

The project spans a number of native vegetation communities

Threatened Flora:

Two threatened plant species have been identified in the project area, the Drooping Red Gum and Dwarf Kerrawang. Both are Commonwealth and NSW listed threatened species,

The Drooping Red Gum (Eucalyptus parramattensis subsp. Decadens) has been recorded throughout the Drooping Red Gum low woodland complex and as scattered trees across some areas of Smooth-barked Apple/Red Bloodwood and Scribbly Gum Open Forest and Scribbly Gum Open Forest. This species occupies an area of approximately 6 hectares within areas of the project footprint that require clearing. Within the operational area of the Base species were fragmented and located in highly modified vegetation communities.

Dwarf Kerrawang (Rulingia prostrata) has the potential to occur in the study area despite not being located during the field surveys. Previous field surveys recorded a number of individuals within the OLA footprint on land rehabilitated after sand mining.



Threatened Fauna:

Two threatened fauna species were positively recorded from the field investigations: the Koala (Phascolarctos cinereus) and Wallum Froglet (Crinia tinnula); both listed as vulnerable species under schedule 3 of the Threatened Species Conservation Act 1995 (NSW).

Koala (Phascolarctos cinereus) Status - Venerable NSW & Cwlth The Scribbly Gum, Drooping Red Gum and Swamp Mahogany are preferred habitat of Koalas. Field surveys within the confines of the Base identified evidence of one Koala individual, further studies will be required to assess koala numbers in the EO and NW runway sections of the project.

Wallum froglet (Crinia tinnula) Status - Venerable NSW The freshwater swamp habitat located to the north-west of the NACC Facilities and adjacent to the proposed access road support a large population of the threatened Wallum froglet (Crinia tinnula), as well as, a diversity of ground and tree-frogs. Freshwater swamp habitat occurs throughout lower lying areas of Low Woodland and Wet Shrubland Complex, with the size of the swamps varying from several square metres to several hectares. Water levels in the swamps are expected to fluctuate seasonally depending on rainfall. The Wallum froglet has also been recorded in flooded areas in the vicinity of the NACC Precinct during wet conditions.



Other threatened species that may be encountered include:

Grey-headed Flying-Fox (Pteropus poliocephalus) Status - Venerable NSW & Cwlth Occupy a wide range of habitats of tropical and sub-tropical forests and woodlands, as well as urban remnants and landscapes. Foraging habitat is widely distributed through the area and local records occur in proximity. Foraging individuals are expected to occur in the locality, although no roosting colonies recorded.

Squirrel Glider (Petaurus norfolcensis) Status - Venerable NSW Prefers forest and woodland habitats, particularly areas with a diversity of eucalypt species in the canopy and other suitable food resources (shrubs and small trees). Requires tree hollows for denning.

Long-nosed Potoroo (Potorous tridactylus) Status - Venerable NSW Preferred habitat is open forests and heath on sandy soils

Pests, weeds and disease

Several weed species of national significance including the Bitou Bush (Chrysanthemoides monilifera) and Lantana (Lantana camara) have been identified on the base

Pests occurring at the Base include rabbits, hares, foxes, cats, birds and rodents. Macropods (i.e. Red Neck Wallabies and Eastern Grey Kangaroos) are a problem for the safety of operating aircraft. Phytophthora cinnamomi (Pc) a soil borne fungus that can cause dieback of native vegetation has been identified at the Base. The Northwest ORP, elements of the proposed access road and EO area and NW runway take-off and landing clearance are located in high risk Pc areas Myrtle Rust, although not detected on the Base had been detected on the Central Coast and across eastern NSW. Myrtle Rust is an exotic fungus from South America which infects the leaves of plants from the Myrtaceae family (e.g. Gum trees (Eucalypts), Bottle Brush, Tea Tree etc.) leading to the loss of leaves and death of plant.



Work in areas of Pc risk requires a strict hygiene and management protocol to manage the risk of spreading the infection.

The key aspects of the Project that could result in adverse impacts on flora and fauna include:

clearing activities;

establishment of ancillary facilities such as stockpile sites, compounds and sediment basins;

construction of waterway crossings;

construction of drainage structures;

chemical usage near waterways and sensitive vegetation;

inadequate or absent erosion and sediment control devices;

exposure of disturbed areas;

delivery and movement of plant and equipment; and

changes in hydrology and drainage regimes.

The potential flora and fauna impacts that may occur during construction include:

loss of habitat value and biodiversity;

reduction in plant numbers and diversity;

barrier to normal fauna movement/migration;

direct mortality and injury to fauna;

damage or death of individual plants due to physical impact;

fragmentation of habitat and decrease in connectivity and fauna passage as a result of vegetation clearing;

disease and weed infestation;

aircraft bird / macropod strike,

increases in pest / vermin such as rabbits, rats and foxes

decline in aquatic habitat quality through changes in water course, decline in light penetration and inadequate erosion and sediment control.

Key Legislation / Standards / Guidance

Commonwealth:

Environmental Protection and Biodiversity Conservation Act 1999

Environmental investigations have concluded that the project is not likely to have significant adverse impacts on flora and fauna or indigenous and non-indigenous heritage; however a general permit under Section 201 of the EPBC Act is required for activities that may kill or injure a listed threatened species or ecological community.

State:

While state legislation does not apply to Defence activities, Defence aims to be good environmental stewards and comply with State government legislation and policies to the extent that these do not conflict with Commonwealth legislative obligations or compromise operational objectives or capability.



NOTE: State Legislation does apply to Activities carried out outside of Defence land. The relevant State environmental legislation and planning instruments are described below.

Protection or the Environment Operations Act 1997 (POEO Act)

Regulates air, noise and water pollution and transport and disposal of waste in NSW

Threatened Species Conservation Act 1995 (TSC Act)

Provides for the protection of critical habitat and threatened species, populations and ecological communities and their habitats in NSW. Where significant impacts are likely the TSC Act requires a Species Impact Statement (SIS) be prepared. Assessments carried out for this project under TSC Act requirements concluded that no significant impacts on threatened species, populations, endangered ecological communities or their habitats as a result of the project provided mitigation measures were implemented. As such no SIS is required.

Native Vegetation Act 2003 The Native Vegetation Act 2003 (NV Act) aims to prevent broad scale clearing to protect native vegetation of high conservation value and to improve the conditions of existing native vegetation An assessment of the clearing required for the project was undertaken and concluded that there would be no significant impacts on native vegetation as a result of the project provided mitigation measures were implemented.

Noxious Weeds Act 1993 The Noxious Weeds Act 1993 (NW Act) provides for the classification and management of noxious weeds and places obligations on owners and occupiers of land to control and prevent the spread of such weeds.

National Parks and Wildlife Act 1974(NP&W Act) The National Parks and Wildlife Act 1974 provides for the establishment and management of National Parks, reserves, historic sites and for the protection of native fauna, flora and Aboriginal heritage. Under Part 7 it is an offence to harm protected fauna unless done so under a license, permit or in accordance with a conservation agreement. Under Part 8A, it is an offence to harm, pick, buy, sell or damage listed threatened species, populations and ecological communities and their habitats, or critical habitats without

approval. Under Section 90 of the Act, it is an offence to knowingly destroy, deface or disturb an Aboriginal object or place without approval.

SEPP 44: Koala Habitat SEPP 44 encourages the conservation and management of natural vegetation that provide habitat for koalas to ensure permanent free-living populations are maintained over their present range. Local councils cannot approve development in an area affected by the policy without an investigation of core koala habitat. Assessments have concluded that the project will not have a significant impact on the Koala.

Pre-clearing surveys have been completed to identify the areas to be protected. These areas are fenced and signposted.

Be aware of habitat trees still within the footprint to be cleared. These trees are marked with red tape for easy identification.

All potential habitat trees must be checked for native fauna by a qualified person prior to clearing (as far as practical)

If native animals are observed in any tree to be felled, stop work immediately and contact the Environmental Officer who will arrange for the animal to be removed

If an injured animal is found, advise the Environmental Officer immediately.

The limit of clearing is identified with red and white danger tape.

DO NOT clear outside these limits without prior approval from the Environmental Officer

Clear only that vegetation within the limit of clearing.

No haul roads, access tracks, laydown, stockpiles etc. is permitted within vegetation protected areas.

Ensure that all stock piles are placed away from residents, creek and fenced vegetation protection areas (EEC). Maintain clear access to mulch stockpiles in case of fire

Inspect fallen habitat trees for the existence of fauna

Minimise ground disturbance near creek banks. Where possible, chainsaw trees at ground level leaving stump within the ground to aid in stabilisation of the bank area and faster regeneration. Maintain ground cover around watercourses to avoid the creation of large exposed areas (i.e. limit disturbance where practical)

All vegetation cleared will be re-used where possible. It will be either stockpiled for milling purposes/construction materials or mulched for re-use in landscaping. Follow directions of Foremen

Locate mulching machinery as far away from residents as practical to avoid un-necessary noise complaints.

Water sprays, sprinklers and water carts will be employed to adequately dampen stockpiles, work areas and exposed soils to prevent the emissions of dust from the site.

• Check the clearing plan attached each time a new area is to be cleared – so you are familiar with the area and the protection areas

PHYTOPHTHORA CINNAMOMI (PC) HYGIENE REV: 0

DATE: 10 SEP 2014

EWMS 002

PROJECT: NACC - RAAF BASE WILLIAMTOWN



Appendix C - Phytophthora cinnamomi hygiene procedures

1. BACKGROUND:

Phytophthora cinnamomi (Pc) has been detected in areas of the RAAF Williamtown. Phytophthora (pronounced fy-TOFF-thora) is a water mould that survives in water, soil and plant roots and kills plants by attacking and rotting their roots.

Phytophthora is spread naturally in water and via infected roots, and faster and further by humans moving contaminated soil or plant material. It can remain dormant for long periods during dry weather and is virtually impossible to remove from infected areas. Phytophthora Dieback attacks many native plants and can also impact on native animals, including marsupials, birds, reptiles and insects, by reducing or eliminating vegetation they rely on for survival.

Even plants that are not highly susceptible will succumb during long periods of dry weather. The loss of root mass limits the amount of water and nutrients a plant can absorb, leaving it susceptible to insect attack, plant diseases and drought stress. Early symptoms of dieback in plants include wilting, yellowing and drying out of leaves

The spores of Phytophthora can persist indefinitely in an area protected in the roots of plants, even those that are not susceptible to Phytophthora Dieback. Disease depends on three essential components: plant host, environment and the pathogen. Phytophthora is most active when the soil is moist and warm. It can also survive for long periods in plant tissue and soil during dry soil conditions. The only effective way to limit it’s spread by managing water and soil movement. Typically infection is restricted to the roots and bottom 1 – 2m of the trunk.

High Risk Activities for Pc introduction and spread include: • earthworks • situations where more than one access point into any given work area is required • heavy vehicles and machines involved - increased risk of contamination spread and complexity and cost of clean down • vegetation clearing

2. Pc MANAGEMENT STRATEGY

Management Strategies to prevent introduction of Pc infected material to uncontaminated areas of the Base, or spread of Pc infected material between areas of the Base or to off site areas will include: Preventing introduction — keep it out

Hygiene Procedures - o All plant, equipment and people (footwear) coming into site is free of dirt and vegetation o All plant, equipment and people (footwear) coming into High or Medium Pc risk areas is to be disinfected. o Provide washdown bays and disinfection sprays / footwash stations at entry and exit points



DATE: 10 SEP 2014

EWMS 002




Use only uninfected raw materials.

Limiting the spread - preventing cross-contamination

Plan work packages to reduce movement of plant and equipment in and out of High or Medium Pc risk areas.

Limiting the points of access to High or Medium Pc risk areas, using fencing to physically segregate High or Medium Pc risk areas

Hygiene Procedures - o All plant, equipment and people (footwear) moving between or leaving High or Medium Pc risk area is free of dirt and vegetation, and is disinfected o Provide washdown bays and disinfection sprays / footwash stations at entry and exit points

Reuse excess soil within the area from which it came.

Manage clearing to keep potentially contaminated root balls, ground cover (grubbing) material and soil separate from uncontaminated trunk and crown vegetation.

Mulch uncontaminated vegetation for reuse within the area of origin or within Low Pc Risk areas, and dispose of potentially contaminated material to an appropriately licensed waste facility

3. OBJECTIVES OF THIS eWMS:

Minimize the risk of spread or introduction of Pc in areas not affected by Pc on RAAF Base Williamtown and external to RAAF Base Williamtown.

4. AREA/LOCATION OF ACTIVITY/SITE:

For the purposes of this eWMS all areas shown on the attached Pc risk assessment map as High or Medium Pc risk will be known as Pc Control Areas, unless otherwise indicated by a Pc testing program.

5. TIMING OF WORKS/EXPECTED DURATION:

At all times working in areas of High or Medium Pc risk (see Risk Map below)

6. APPROVALS REQUIRED:

Environmental Clearance Certificate approved by Defence.

7. CONSULTATION REQUIREMENTS:

Consultation with Managing Contractor and RAAF Williamtown SEM prior to entry to High or Medium Pc risk.

Prior to commencement of works in Pc Control Areas

Plan works in Pc Control Areas

Work not planned to minimise risk of cross contamination between areas

• Package work activities that are a significant risk for Pc spread or introduction (based on Pc risk map and activity type) within an area to minimise movement of plant, equipment and personnel between areas during that activity.

• Conduct planning meetings with personnel and sub-Sub-contractors to communicate Pc risks and develop management measures consistent with this plan.

• Include Pc control measures on the location / activity specific ESCP • Plan to include limit to access points to Pc Control Area and provide appropriate hygiene controls. • Planning may include a program of testing designed by a competent party to demonstrate absence of Pc

in an area. In the absence of this testing, as discussed above, all Medium and High Pc Risk areas will be considered as Pc contaminated and designated Pc Control Areas.

Project Manager Supervisor

ECC Approval Works not approved • Consider Pc risk in ECC application • Include proposed mitigations and location / activity specific ESCP showing proposed controls

Working in Pc Control areas

Whilst working in Pc Control areas – General conditions

Spreading Pc to further areas.

• Ensure equipment is clean • Ensure raw materials are Pc Free. • Where ever possible

o Avoid leaving formed areas. o Avoid working in wet weather. o Avoid sites prone to flooding or ponding. o Work downhill of vegetation. Pc moves rapidly downhill on surface water runoff, while uphill

movement occurs much more slowly • Stay within cleared areas, avoid disturbing native vegetation. • Any water used needs to be drawn from a source that is Pc f r e e – mains water is best • Do not drive vehicles through drainage lines, creek lines or puddles. • Do not drive over vegetation to turn vehicles. • Do not enter vegetation without disinfecting footwear – Pc can be carried on a very small amount of

soil. • Always disinfect tools prior to beginning works and when moving from one area to another. • Wash down vehicles when moving between work sites, or leaving the Pc Control Area • Always work in areas where there is no infection before moving to infected areas


During Earthworks Spreading Pc to further areas.

• Plan erosion and sediment controls to prevent runoff from worksite into surrounding vegetation. • Apply adequate dust suppression to minimise dust generation, however avoid excess water application

generating runoff to surrounding vegetation. • Only mains water, or standing water from within the Pc Control Area should be used for dust

suppression, surface or groundwater collected from outside the Pc Control Area must not be used. • All activities must be carried out to minimise soil movements and transport of soil and water.

Fill Materials Import of Pc contaminated materials

• Sources of fill should be certified Pc free before use.

Working in drains / culverts and wet areas

• Keep tyres / tracks on roadways /hardstand at all times and do not drive over vegetation or into drains. • Drains and culverts should only be cleared in dry conditions.

Excess Spoil and stockpiles Spreading Pc to further areas.

• Spoil should be reused within the Pc Control Area it came from. • Where reuse within the Pc Control Area is not possible the material must be tested and confirmed Pc

free before reuse in other areas, or disposed of to an appropriately licenced waste facility. • Stockpiled material should not be placed near native vegetation and should be contained by a silt fence

to minimise erosion by run on water and sediment transport into vegetation.

Parking and laydown • Never in vegetated road verges (including slashed road verges) or within vegetation. • Where possible down slope of vegetated areas and on constructed hard stand areas.

Potential Hazards


Safeguards/controls


Responsibility


Clearing, Grubbing and Mulch

Clearing within Pc Control Areas


• Trees should be stump cut, leaving 1 to 1.5m of the trunk upstanding. • The felled section of trunk and crown should be kept as soil free as possible and mulched as soon as

possible. • The mulch should be stockpiled on hardstand if available to minimise soil contamination and should be

protected with a sediment fence. If managed this way this mulch is considered low risk for Pc transfer and can be used for ERSED control or landscaping within the Pc Control Area it originated from or in the low Pc infection risk areas (see Risk Map)

• The remaining stumps, root-balls and grubbed up ground cover should by collected up, placed in a covered skip bin or truck and taken to a suitably licenced waste facility for disposal (NOTE the waste facility must be aware of the potential for Pc contamination and must not mulch this material).

• Alternatively where the stumps, root-balls and grubbed up ground cover can be mulched in a separate area within the Pc Control Area, away from native vegetation and managed by appropriate sediment controls, and a suitable number of lab tests are negative for Pc infection, this material may be reused within the Pc Control Area from which it originated.

• Alternative disposal options, such as firewood, may be considered where the risk of Pc infection transfer can be demonstrated to be low.

• Where it is not practical to stump cut trees, and a dozer or other mechanical means are proposed to push the trees over, the resulting vegetation must be either tested to demonstrate absence of Pc or disposed of to a suitably licenced waste facility.


Wet Weather

During Wet Weather While working in Pc Control areas


• Whenever possible avoid work earthwork or work involving contact with the soil during wet weather, or when soils are still wet/damp after rain.

• If rains begin when working, then works should stop and you should contact the Managing Contractor for advice.

• If you are not working in an area where you are likely to move mud or soil around on vehicles or boots then it is likely that work can continue.

• Grading of roads can occur if the surface is damp, but not wet. • Do not, under any circumstances, enter vegetation when it is raining, or just after rains, or if soils

are damp – even if you have cleaned your boots / tools. • No revegetation or rehabilitation activities should be undertaken in wet weather.

Washdown / cleaning Procedures

Plant / vehicles prior to entering or leaving Pc Control areas

Spreading Pc to previously unaffected areas

• Safely park vehicle or plant in the wash-down area. Ensure engine is off and vehicle is immobilised. • Look over vehicle to locate any soil. Pay attention to underside, tracks, tyres (inc. the spare) axles and

bumper bars etc. • Knock off large clods of soil - use crow bar if required, sweep out cabin and other areas. • Use broom or air hose to remove as much soil as possible. Brush off any remaining dry soil. • Start with underside of vehicle, wheel arches, wheels (including spare). Next do sides, radiator, tray,

bumper bars etc., finishing with upper body. Tracked machinery may need to be moved during wash down.

• Clean any associated implements, tools, footwear and equipment. Check there is no loose soil remaining.

• Spray with quaternary ammonia solution e.g.: Phytoclean® • Wash away effluent. Do not drive through effluent. Note: Wash-down water is to be captured and disposed of to an appropriately licenced waste facility. Collected soil can be reused as fill within the Pc Control Area, or disposed of to an appropriately licenced waste facility, it is not to be reused outside the PC Control Area it came from.

Responsibility


Footwear prior to entering or leaving Pc Control areas


Some personnel will require a personal Pc hygiene kit to work on the base. Keeping footwear clean is vital in minimizing the risk of spreading Pc. Footwear should be cleaned prior to entering and upon leaving a works area and immediately before and after going off tracks or entering vegetation (even slashed road verges), although this should be avoided wherever possible.

Ensure you disinfect your boots where they will not pick up soil again once you put them down. Personal Pc hygiene kits should contain: • Hard brush to clean footwear. • Spray bottle containing Phytoclean* The spray bottle should be adequate in removing the soil from

your footwear. Cleaning Procedure:

1. Select a hard well-drained site – (or sitting in your vehicle); 2. Remove all plant and soil from one boot with the brush (if necessary); 3. Do not put that boot on the ground or onto surfaces where there is soil; 4. Disinfect the entire sole with the disinfectant (and any other areas of the shoe with soil). The nozzle

of the spray bottle should be on ‘direct’ so that as much soil as possible is physically removed by the spray;

5. Allow the sole of the shoe to dry – for Phytoclean 30 seconds is enough; 6. Step forward to avoid recontamination (do not step onto areas where you will recollect soil); 7. Repeat steps 2 to 6 with other boot; 8. Disinfect the brush.

Alternatively a cleaning station may be provided including boot scrappers and footbath for personnel to pass through when entering and leaving the work area.

Tools and equipment prior to entering or leaving Pc Control areas


Tools should be treated in the same manner as footwear –

• once works have finished in an area, remain in that area, • use the brush to remove any large amounts of soil from each tool, • disinfect with Phytoclean, allow to dry for 30 seconds. • Repeat this measure if tools come into contact with soil after disinfecting, or in vehicles.

*Phytoclean® is a hard surface application treatment which is classified a non- hazardous product. Phytoclean® is high in detergency and washability ensuring there is no residue when used in washdown situations and is effective in as little as 30 seconds. Phytoclean® is a quaternary ammonium solution.

Fauna Rescue and Release Guideline

Introduction

Construction projects invariably interact with local fauna species during clearing of vegetation or ongoing construction works. This guideline has been developed to ensure that any fauna encountered during clearing or ongoing works are treated in the most appropriate manner to ensure their safe handling and release back to their natural habitat.

This guideline is therefore split into 2 sections, being:

1. Fauna Rescue; and

2. Fauna Release

1. Fauna Rescue Guidelines

It is assumed that fauna encountered during selected habitat searches and recovery will, in most cases, comprise commonly occurring native vertebrates.

Immediately prior to clearing, the project Ecologist will conduct pre-clearing fauna surveys within each area to be cleared. Where hollow bearing trees

(HBT) are present a two-stage clearing protocol will be implemented to provide maximum opportunity for fauna to relocate to nearby retained vegetation and minimise fauna injury.

However, if an animal (including injured, shocked or juvenile) or eggs are discovered during the pre-clearing survey, during clearing itself or at any time during construction, the following guidelines should be followed:

1a. Planning for Rescue

Basic equipment for fauna rescue (cotton bags, canvas bags, gloves) will be kept in on site for emergency use by site staff if required. The Project Ecologist or wildlife handler will also carry appropriate fauna rescue kit whilst on site.

The Environmental Manager will hold the contact details of fauna rescue services, local veterinary surgeons and the Project Ecologist. Contact details will be made readily available to site staff at all locations where clearing is to be undertaken.

1b. Fauna Rescue

If fauna require handling, this will be done with care and by the licensed fauna handler where available. In emergencies fauna may also be handled by the Environment Coordinator or other nominated personnel.

Provide appropriate temporary housing for rescued fauna that is species-dependent. This includes:

Gliders, possums, bats, snakes, lizards and frogs can be held individually in a cotton bag until release in adjacent habitat.

Nestling birds and eggs are best placed in a covered cardboard box equipped with soft cloth.

For large animals it is best to cover the animal with a towel or blanket first to minimise stress and firmly but gently place it in a cardboard box, or natural fibre bag.

Smaller animals, can be placed in a cotton bag, tied at the top.

Any fauna which cannot be released immediately or by the evening of the day clearing occurred will be handed to wildlife rescue personnel.

Rescued fauna must be protected from exposure to heat and removed from the areas undergoing clearing or construction activities to minimise exposure to noise. Keep the animal in a quiet, cool, ventilated and dark place.

If the animal is seriously injured and requires immediate attention, as determined by the Project Ecologist or Wildlife Handler, the rescue agency should be contacted immediately or taken directly to a veterinary practice.

If the Project Ecologist or Wildlife Handler is not present when an injured/juvenile animal is found, the rescue agency should be called immediately.

If the animal does not require immediate attention, as determined by the Project Ecologist or Wildlife Handler, the rescue agency should be called in the afternoon and they would collect any animals requiring attention.

If the animal is reluctant to move away or is injured, then it should not be released and a fauna rescue agency should be contacted.

Some animals require particular handling (e.g. venomous reptiles, raptors) and should not be handled by site personnel. If the animal cannot be handled, record the exact location of the animal and contact the rescue agency. If possible a spotter should monitor the location of the animal from a safe distance.

Once the rescue agency arrives at the site, they would be responsible for the animal. Any decisions regarding the care of the animal would be made by the rescue agency.



If the rescue agency cannot be contacted, the Project Ecologist or Wildlife Handler would deliver the injured/captured animal to the agency as soon as practically possible.

Any drivers of vehicles in recently cleared areas are to be made aware that fauna may still be in the area (e.g. koalas, kangaroos), and are at risk from vehicle collisions.

Identified local fauna rescue agencies and contacts as at November 2014 include:

1c. Post Fauna Rescue

After the completion of fauna relocation, a brief record detailing the findings of the survey and relocation will be prepared, including details of:

Any live animals that are sighted, captured, released, injured, shocked or killed as a result of clearing operations and fauna rescue.

Tree species being used for breeding or roosting by fauna, including tree locations, sizes, heights and depths of hollows.

2. Fauna Release

If the animal is not injured, it may be released nearby in an area that is not to be disturbed by the road construction in accordance with the following guidelines:

Prior to any clearing works, several sites within or near the project site would be identified as suitable release points by the Project Ecologist or Wildlife Handler.

The Project Ecologist or Wildlife Handler would be primarily responsible for undertaking any release, or advising site personnel on release processes if not present on site.

If the species is nocturnal, release would be carried out at dusk.

No release would take place during periods of heavy rainfall, unless the Project Ecologist or Wildlife Handler determines that the animal is too stressed to be held any longer.

Any fauna which cannot be released immediately or by the evening of the day clearing occurred will be handed to wildlife rescue personnel.
