Yellow-tailed Plain Slider (Lerista xanthura)
The Yellow-tailed Plain Slider is a small, fossorial skink with reduced limbs and a bright yellow tail. It occurs in arid and semi-arid parts of mainland Australia, including sandy habitats that may be affected by clearing, earthworks, grazing and changed fire regimes. It is listed as Vulnerable in New South Wales and should be treated as an EVNT species during planning, assessment and site works.
Conservation status
New South Wales, Biodiversity Conservation Act 2016: Vulnerable.
Breeding season
The Yellow-tailed Plain Slider is an egg-laying skink, but its breeding months are poorly known. The general pattern shown is a cautious guide for an arid Australian skink, with activity likely influenced by local rainfall, temperature and habitat condition.
Breeding mode: Oviparous, lays eggs.
Breeding timing: Not recorded. A warmer-month breeding period is used as a general planning guide only.
Clutch size: Not recorded.
Incubation period: Not recorded.
Age at maturity: Not recorded.
Nest or laying site: Not recorded. The species is fossorial and uses loose soil or sand beneath stones, logs and other surface debris.
Timing may vary between regions and years, particularly after rainfall, drought or fire, so avoid relying on calendar timing alone when planning clearing or construction.
- General activity and foraging: Individuals may be present in loose soil, sand and surface debris throughout the year, with activity affected by local weather and rainfall.
- Likely breeding activity: Spring and summer are a general planning guide for mating and egg laying, not a confirmed species-specific season.
- Eggs or young in shelter sites: Eggs or young may occur in soil or debris shelters during and after the likely warmer-month breeding period, but timing and development are not recorded.
- Sheltering in soil and surface debris: Retain loose soil, sand, logs, rocks, leaf litter, grass cover and spinifex in every month.
- Highest clearing risk: Risk is highest during the general breeding and early young period, but fossorial individuals and shelter habitat can be affected by works at any time of year.
Identification: Appearance and size
The Yellow-tailed Plain Slider is a small skink that spends much of its time in loose soil or sand. It has a distinctive yellow tail, but its small size and cryptic habits make field identification difficult.
The body is pale pinkish-buff to pink, sometimes with brown-edged upper scales. The underside is whitish and the tail is long and bright yellow.
The body is elongate. Both pairs of limbs are reduced and have four digits. Adults reach about 90 mm in total length, with a snout to vent length of about 40 to 45 mm.
Forelimbs: Reduced, about 6 mm in the described measurements.
Hindlimbs: Reduced, about 12 mm in the described measurements.
- Look for a small, slender skink with a bright yellow tail.
- The species has a distinct ear opening, two preocular scales and no upper lateral stripe.
Identification: Calls and similar species
No call or other vocal signal is available for reliable field identification. Do not rely on auditory detection.
The species belongs to the Plain Slider group of Lerista skinks. The Desert Plain Slider is a close relative and was formerly treated as the same species. The Yellow-tailed Plain Slider is generally paler and has longer limbs and two preocular scales, while the Desert Plain Slider has one preocular scale.
- Have a suitably experienced herpetologist confirm uncertain records.
- Photograph the animal, including the head, limbs, tail and side of the body, where this can be done without causing harm.
Identification: Field signs
There are no distinctive droppings, nests, whitewash, stains or odours that can be used confidently to confirm presence. Tracks are unlikely to persist in loose sand and are not a dependable survey sign.
Search records may come from animals found beneath surface cover rather than from obvious above-ground activity.
- Record the exact location and habitat when an animal is found.
- Replace stones, logs and other cover carefully after inspection.
- Avoid excessive turning of cover, soil disturbance and repeated handling.
Distribution: Australian range
The Yellow-tailed Plain Slider is an Australian mainland species associated mainly with arid and semi-arid regions. Its distribution is poorly resolved because records are scarce and it can be confused with similar sliders.
The mapped Australian range includes New South Wales, the Northern Territory, Queensland, South Australia, Victoria and Western Australia. The broader known range extends from the Gibson Desert through central Australia to far-western New South Wales.
Records and published descriptions particularly identify the Gibson Desert and the Little Sandy Desert in Western Australia, central Australian deserts, and the Lower Murray Darling and far-western regions of New South Wales.
- In New South Wales, known areas include the country between Ivanhoe and Broken Hill and the north-west corner of the state.
- New South Wales records include Kinchega National Park, Mutawintji National Park, Sturt National Park, Tarawi Nature Reserve and Broken Hill.
- Records are sparse. Only nine New South Wales records have been reported since the 1970s in the cited assessment.
Distribution: Distribution on works sites
A lack of records should not be treated as proof that the species is absent. Suitable sandy habitat can be extensive, and the species may remain underground or beneath surface debris during a site inspection.
For project planning, check both database records and habitat continuity around the development footprint. Give particular attention to connected sand plains, dunes and alluvial sandy areas.
- Map all suitable habitat within and around the disturbance footprint.
- Retain links between sandy habitat patches where practicable.
- Escalate unexpected finds to the project ecologist and relevant state authority requirements.
Distribution: Overseas range
The Yellow-tailed Plain Slider is endemic to Australia. No overseas range is recognised.
Habitat: Vegetation and landforms
Look for the Yellow-tailed Plain Slider in loose sandy substrates in arid and semi-arid country. Habitat quality depends on intact ground cover, surface debris, soil structure and a suitable invertebrate food base.
Suitable habitat includes grassed alluvial sands, sand dunes, dry open woodlands and spinifex-dominated red sand plains. The species is also associated with sandy desert and mallee environments.
On a works site, inspect sandy rises, red sand plains, alluvial sand deposits and areas of open woodland with a relatively intact ground layer.
- Spinifex and other hummock grasses.
- Grassed alluvial sand.
- Dry open woodland.
- Mallee and sandy desert vegetation.
- Dunes and connected sand plains.
Habitat: Habitat features to retain
The species uses loose soil and sand beneath stones, logs and other surface debris. Fallen timber, leaf litter, rocks, grass cover, spinifex, understorey shrubs and soil cracks can all contribute to suitable habitat.
Avoid unnecessary removal or stockpiling of these features. Keep retained habitat connected and protect it from vehicle movement, soil compaction and construction storage.
- Mark exclusion areas before clearing begins.
- Keep machinery, spoil, fuel and materials out of retained sandy habitat.
- Use fencing where needed to prevent stock access and trampling.
- Retain natural ground cover and surface debris wherever possible.
Habitat: Habitat condition
Grazing, trampling and altered fire regimes can reduce vegetation structure, soil quality and the amount of surface debris available for shelter. Cleared or heavily compacted areas may have lower habitat value, even where sandy substrate remains.
Assess the surrounding landscape, not only the immediate footprint. A small disturbed area may still affect a fragmented population if it removes the remaining suitable cover.
- Check for soil compaction, erosion and extensive bare ground.
- Record grazing pressure, goat activity and recent fire history.
- Identify whether suitable habitat is continuous or isolated.
Foraging habitat: Food and feeding areas
The Yellow-tailed Plain Slider is insectivorous and searches for small invertebrates in loose soil and around ground cover. Foraging areas are likely to overlap with sheltering habitat, so clearing and surface disturbance can affect both functions at once.
The diet includes ants, termites and other small insects. Food is associated with loose soil, stones, fallen timber, leaf litter and, in some accounts, termite mounds.
On site, look for sandy ground with active ground-layer vegetation, retained litter and surface objects that support invertebrates.
- Loose sand and soil beneath stones and logs.
- Leaf litter and fallen timber.
- Spinifex and grassed areas.
- Termite mounds and other areas with visible invertebrate activity.
Foraging habitat: Works risks
Clearing, grading, topsoil removal, compaction and repeated vehicle traffic can remove feeding cover and reduce soil invertebrates. Broadscale fire or frequent burning can also reduce litter and ground structure.
Do not assume that an area is unsuitable because no animals are seen above ground. The species may be below the surface or under cover during the inspection.
- Keep vehicles on defined access routes.
- Avoid unnecessary grading and removal of the natural soil profile.
- Retain logs, rocks, litter and hummock grasses in undisturbed areas.
- Prevent stock and feral goats from entering retained habitat where practicable.
Foraging habitat: Field approach
Target surveys at representative sandy habitats and inspect surface cover carefully. Because species-specific detection methods and effort requirements are not well established, use an experienced reptile ecologist to design the survey around local conditions and the proposed disturbance.
- Search a range of habitat features rather than relying on one cover type.
- Record the type and condition of each item of cover inspected.
- Replace lifted cover immediately and minimise handling time.
- Treat any confirmed or suspected individual as a significant find on a development site.
Breeding habitat: Known breeding information
The Yellow-tailed Plain Slider lays eggs, but its breeding sites and breeding season are poorly understood. Work planning should therefore avoid disturbing suitable sandy habitat and potential refuge areas during all stages of the project.
The species is oviparous. Specific nest sites, egg-laying locations, clutch size, incubation period and breeding timing have not been established in the available field information.
Do not assume that breeding habitat is restricted to a particular vegetation type. Suitable loose sand, soil cracks and sheltered ground features may be relevant until local evidence indicates otherwise.
- Treat connected sandy habitat as potential breeding habitat.
- Retain undisturbed ground cover, logs, rocks, litter and soil structure.
- Seek specialist advice if eggs, hatchlings or a gravid individual are found.
Breeding habitat: Protection during works
Before clearing, identify areas that can be avoided and fence them clearly. Keep construction traffic, trenching, spoil placement and materials storage outside retained habitat.
If clearing is unavoidable, use a staged approach and have an experienced fauna spotter catcher present. Stop work if a Yellow-tailed Plain Slider or possible eggs are found, and follow the project fauna handling and notification procedure.
- Brief all operators about the species and its habitat.
- Use pre-clearance checks focused on loose sand and surface cover.
- Do not excavate or search suspected breeding features without ecological direction.
- Record all observations and any breeding evidence.
Breeding habitat: Knowledge gaps
Breeding biology is not well known, and there is no reliable month-specific breeding window to use for avoiding impacts. Apply a precautionary approach across the construction program, particularly where sandy habitat and surface refuges will be removed.
Sheltering habitat: Shelter features
The Yellow-tailed Plain Slider is fossorial and usually shelters in loose soil or sand beneath surface debris. Retaining these small-scale refuge features is one of the most practical ways to reduce harm during site works.
Potential shelter occurs beneath stones, logs, tree stumps, leaf litter and other surface debris. Loose sand, soil cracks and hummock grasses can also provide cover.
Inspect sheltered sandy areas carefully before disturbance. A site can appear open and dry while still supporting animals below the surface.
- Loose soil and sand.
- Stones and fallen timber.
- Tree stumps and leaf litter.
- Spinifex, grass cover and understorey shrubs.
- Soil cracks and termite mound margins.
Sheltering habitat: Fire and ground disturbance
Overly frequent or non-patchy fires can reduce surface debris and alter vegetation structure. Fire can also kill animals directly and change the soil and litter conditions used for shelter.
Avoid unnecessary burning in or beside suitable habitat. Any fire regime should retain unburnt refuge areas, fallen timber, litter and hummock grasses.
- Plan fire treatments to retain a mosaic of shelter areas.
- Do not burn retained habitat solely to improve visibility for clearing.
- Record recent fire extent and severity during the habitat assessment.
Sheltering habitat: Handling and exclusion
If an animal is exposed during clearing, stop work around the find and allow the fauna spotter catcher or ecologist to assess it. Keep the animal shaded and handle it as little as possible.
Release or relocation decisions must follow the project approval, fauna management plan and advice from the attending ecologist. Do not move animals informally to another part of the site.
- Use clearly marked no-go areas around retained shelter habitat.
- Keep excavations, trenches and spoil piles away from sandy refuge areas where possible.
- Check open excavations for trapped fauna in accordance with the site fauna procedure.
Threats: Clearing and fragmentation
The main risks are habitat loss, fragmentation, soil damage, altered fire regimes and introduced predators. These pressures are more serious where local populations are small or isolated, as is likely in parts of the species' range.
Clearing for roads, compounds, services, access tracks and other infrastructure can remove sandy habitat and surface refuge. Fragmentation can isolate small populations and increase their exposure to drought, fire and other chance events.
Avoid suitable habitat first, then minimise the footprint and restore disturbed areas with local soil and vegetation where practicable.
- Retain connected sand plains, dunes and alluvial sandy areas.
- Keep construction footprints as narrow as practicable.
- Do not use retained habitat for laydown, spoil or vehicle parking.
- Rehabilitate compacted areas promptly after works.
Threats: Grazing, trampling and soil damage
Stock and feral goats can reduce vegetation cover and trample surface refuges. Vehicle traffic and earthworks can compact soil, increase erosion and remove the loose substrate used by the species.
Fence retained habitat where grazing or access cannot be controlled by other means.
- Control vehicle routes and speed within sandy habitat.
- Prevent unauthorised stock access to exclusion zones.
- Manage feral goats and other grazing pressure with the land manager.
- Monitor erosion, bare ground and loss of ground cover after construction.
Threats: Fire and climate pressures
Inappropriate fire regimes can remove litter, logs and hummock grasses, alter plant structure and directly kill animals. Drought, heat, flooding and changing climate conditions may further reduce habitat quality and food availability.
Use a fire approach that retains shelter and avoids uniform burning across suitable habitat.
- Retain unburnt refuges and surface debris.
- Avoid frequent or extensive burns in suitable habitat.
- Include drought, fire and flood risks in long-term site management.
Threats: Predators and site controls
Feral Cats and European Red Foxes eat reptiles, although the specific level of predation pressure on the Yellow-tailed Plain Slider is uncertain. Predation may be more damaging where habitat loss has already reduced local populations.
Coordinate pest control with landholders and the relevant land manager. Keep construction compounds clean and secure so they do not attract prey or provide cover for predators.
- Include cats, foxes and feral goats in site and landscape pest planning.
- Remove food waste and avoid creating artificial shelter around compounds.
- Report records so local distribution and recovery monitoring can improve.
Survey methodology: 1. Desktop assessment
The Yellow-tailed Plain Slider is a small, fossorial skink that can be difficult to detect. Survey should focus on loose sand and soil beneath stones, logs, stumps, leaf litter and other surface debris in suitable arid and semi-arid habitat.
Map grassed alluvial sands, sand dunes, dry open woodland and spinifex dominated red sand plains before works begin.
Review records from government databases, local landholders, national parks and previous project surveys. Give particular attention to disjunct populations and sites near Kinchega National Park, Mutawintji National Park, Sturt National Park, Tarawi Nature Reserve and Broken Hill.
Check the current listing in each jurisdiction. The species is listed as vulnerable in New South Wales and is treated as an EVNT species for this profile. Confirm whether a proposed action requires an EPBC Act referral or approval, and obtain any state or territory permits before handling wildlife.
Typical habitat: Loose soil or sand in grassed alluvial sands, sand dunes, dry open woodlands and spinifex dominated red sand plains
Listing example: Vulnerable in New South Wales
- Map retained habitat, proposed clearing, access tracks, stock areas, fire scars and areas with heavy grazing or trampling.
- Identify locations where fallen timber, rocks, spinifex, grass cover, shrubs and soil cracks can be retained.
- Treat apparently suitable habitat as potential habitat where records are sparse.
Survey methodology: 2. Targeted searches
Search slowly and systematically through suitable habitat. Carefully inspect beneath surface debris, including stones, logs, stumps and leaf litter, then replace each item in its original position.
Use experienced ecologists and fauna spotter catchers familiar with small fossorial skinks. Avoid unnecessary excavation, deep soil disturbance or destruction of shelter sites.
Because detection is likely to vary with temperature, recent rain, soil condition and surface activity, use more than one survey visit where the project risk warrants it. Combine daytime refuge searches with quiet searches during suitable evening conditions, recognising that published accounts differ on activity patterns.
- Search after rain or when the soil is workable, but do not enter unstable or unsafe sites.
- Survey both undisturbed reference areas and the proposed disturbance footprint.
- Increase survey intensity where habitat is continuous, records are nearby or the species has previously been found in the locality.
Survey methodology: 3. Record and assess findings
Record every observation, including animals found under debris, burrows or loose soil. Photograph the animal and habitat where this can be done without prolonged handling.
Map the location with coordinates and record the habitat, debris type, soil condition, weather, time, surveyors, search area, survey duration and detection method.
Record negative results as well as positive results. Low detection rates should not be treated as evidence that the species is absent.
Approximate total length: Up to about 90 mm
Useful identification features: Elongate body, reduced limbs with four digits, pale pinkish-buff colour and bright yellow tail
- Record the animal's condition, approximate size and distinctive features, including the pale pinkish-buff body and bright yellow tail.
- Record nearby threats such as grazing, goat activity, soil compaction, erosion, clearing, fire history, cats and foxes.
- Provide records to the project ecologist and relevant wildlife agency in the required format.
Before habitat disturbance: 1. Confirm approvals and responsibilities
Plan avoidance before machinery arrives. The species has a fragmented distribution and may occur at low abundance, so an apparently empty site still requires a precautionary approach where suitable habitat is present.
Confirm the species' current legal status in the relevant state or territory before finalising the work method.
In New South Wales, obtain the approvals, licences and threatened species authorisations required for work affecting a vulnerable species. In Queensland, check whether the action affects protected wildlife or a breeding place and whether a species management program is required.
Check the EPBC Act referral pathway and current national listings. Obtain written advice where the action could affect a listed matter, even though the assessment status recorded for this species is not nationally listed.
- Nominate the project ecologist and fauna spotter catcher responsible for decisions in the field.
- Confirm who can authorise handling, release, temporary care, work stoppage and recommencement.
- Include the species in the construction environmental management plan and clearing permit.
Before habitat disturbance: 2. Avoid and protect habitat
Redesign the footprint where possible to retain suitable sand habitat and connected patches. Retain ground timber, fallen logs, rocks, grass cover, spinifex, understorey shrubs and soil cracks.
Do not set a generic buffer where a regulator, approval or site assessment specifies another distance. Establish a site-specific exclusion zone around records, retained refuge habitat and any breeding place or shelter site, and mark it before clearing.
Keep vehicles, spoil, laydown areas, refuelling and access tracks out of retained habitat. Prevent stock, goats and other animals from entering fenced protection areas.
- Fence and sign exclusion areas before machinery mobilisation.
- Use existing disturbed access routes wherever practicable.
- Do not move logs, rocks or other debris from retained habitat unless authorised and necessary for approved works.
- Use a patchy fire approach that retains shelter and surface debris. Avoid frequent or broad, uniform burns.
Before habitat disturbance: 3. Complete pre-clearance checks
Carry out a final pre-clearance inspection immediately before disturbance, using the approved survey method and the site's risk assessment. Search the footprint and the edge of exclusion areas for animals and shelter sites.
Inspect debris that will be removed and mark habitat that must remain. Where an animal is found, stop in that area and allow an authorised person to decide whether capture and relocation are permitted.
The species' breeding biology and timing are poorly known. Do not assume that a site is outside a breeding period. Treat eggs, nests, occupied burrows or other suspected breeding places as protected until the relevant authority provides direction.
- Brief the clearing crew on identification, exclusion fencing, the stop-work signal and the reporting chain.
- Check that temporary holding containers, shade and suitable substrate are ready before any approved capture.
- Schedule works to avoid periods of extreme heat, heavy rain and unsafe conditions.
During habitat disturbance: 1. Clear in stages
Use staged clearing and keep a trained spotter catcher present whenever suitable habitat is disturbed. The spotter catcher must have clear authority to stop work without waiting for supervisor approval.
Clear from the least disturbed edge towards retained habitat, allowing animals to move into protected areas where this is safe and authorised.
Remove surface debris progressively and inspect each item before it is moved. Keep machinery outside exclusion zones and maintain a slow, controlled work front.
Do not rake, burn, grade or stockpile loose sand, logs, rocks or leaf litter ahead of the approved clearing sequence.
- Use a pre-start check each day and after any change in the work area.
- Stop work if exclusion fencing is damaged or if unexpected habitat is exposed.
- Keep a clear route for the spotter catcher and emergency access.
During habitat disturbance: 2. Handle animals lawfully and safely
Only authorised and suitably trained people may capture, handle, temporarily hold or relocate the Yellow-tailed Plain Slider. Use the least intrusive method that protects the animal and complies with the permit or approval.
Do not chase animals into deep loose soil or dismantle shelter beyond what is authorised. Keep handling brief and avoid overheating, crushing and desiccation.
Release a healthy animal only where the approval, ecologist and site conditions allow it. Use suitable nearby habitat that is outside the work area and not exposed to immediate machinery, stock or predators.
- Keep animals in secure, ventilated containers with shade and appropriate substrate while awaiting direction.
- Do not release an animal across roads, into unsuitable cleared ground or into another population without written approval.
- Follow the permit conditions for marking, tissue sampling, transport and release.
During habitat disturbance: 3. Respond to discoveries and incidents
Stop work immediately in the affected area if an animal, eggs, an occupied burrow or another suspected breeding place is found. Protect the location from people, vehicles, heat and vibration, then contact the project ecologist and relevant authority.
The species has no documented colony or roost requirement. If a concentrated group or repeated shelter use is found, manage it as a sensitive site and obtain specific advice before disturbance continues.
If an injured animal is found, place it in a secure shaded container only if authorised, minimise handling and contact a licensed wildlife carer, veterinarian or government wildlife officer.
- Record the location, time, cause of injury, condition, photographs and people involved.
- Do not provide food, water or medication unless directed by a qualified wildlife professional.
- Report any death, unapproved handling, escape, damage to exclusion fencing or breach of approval conditions through the project's incident system.
During habitat disturbance: 4. Maintain field records
Keep a daily fauna register for searches, captures, relocations, injuries, deaths, stop-work events and clearance progress.
Link each record to a map, photograph and work area. Record the weather, habitat condition, survey effort and final outcome for each animal.
The fauna spotter catcher and site supervisor should review records at the end of each shift and resolve any outstanding actions before the next clearing stage.
- Record negative searches and areas not inspected because of safety or access constraints.
- Record the release location and time for every relocated animal.
- Retain permit numbers, approval conditions and authority instructions with the site records.
After habitat disturbance: 1. Complete post-clearance checks
Finish each clearing stage with a documented check. Use the results to confirm that the work area is safe, that retained habitat remains intact and that any animals moved under approval have been accounted for.
Inspect the cleared footprint, stockpiles, access routes and exclusion boundaries after machinery leaves. Search remaining debris and disturbed edges for animals that may have been missed.
Check that retained logs, rocks, spinifex, grass cover, shrubs and soil features have not been removed, buried or compacted.
Repeat checks after high-risk activities such as grading, trenching, burning or movement of spoil.
- Repair damaged fencing and remove unauthorised materials from retained habitat.
- Confirm that no animal, egg or occupied shelter has been left in an unsafe location.
- Photograph the completed area and any residual impact.
After habitat disturbance: 2. Report outcomes
Prepare a clearance report that compares planned and actual disturbance. Include survey effort, detections, animals handled, release locations, injuries, deaths, incidents, habitat retained and rehabilitation actions.
Submit records to the approval holder, project manager and relevant regulator within the required timeframe. Share verified records with the state biodiversity database where appropriate.
Report unexpected concentrations, new populations or repeated mortality promptly. These findings may require a revised work method or additional approval.
- Provide maps and spatial files for records and exclusion areas.
- List all permit conditions and state whether each condition was met.
- Document reasons for any departure from the approved method.
After habitat disturbance: 3. Monitor relocated animals and review incidents
Where relocation has been approved, monitor the release site using a method suited to the project risk and approval conditions. Focus on survival indicators, shelter use, habitat condition and threats from grazing, goats, cats and foxes.
Do not assume that a relocated animal has survived because it was released in suitable habitat. The species is poorly known and may be vulnerable to drought, wildfire and predation.
Hold a post-clearance review with the ecologist, spotter catcher and supervisor. Use the findings to improve future surveys, staging and exclusion controls.
- Compare results with a nearby retained reference area where practicable.
- Inspect release areas after major fire, flood, drought or earthworks.
- Escalate evidence of mortality, dispersal into unsafe areas or habitat failure to the relevant authority.
Rehabilitation actions: 1. Restore habitat structure
Rehabilitation should restore the shelter and soil conditions used by this fossorial skink. Aim for connected, structurally diverse habitat rather than a bare, tidy surface.
Replace suitable local logs, rocks and other natural debris where they were temporarily removed and where approval allows. Retain loose sand and soil without compaction.
Re-establish native grass, spinifex, shrubs and woodland structure suited to the local community. Protect regenerating areas from stock, goats, vehicles and repeated fire.
Restore riparian strips, gullies and stream banks where these are part of the project footprint, while preventing erosion and sediment movement into retained habitat.
- Use local provenance seed or approved plant material where available.
- Scarify or decompact soil only where this is needed for revegetation and will not destroy retained refuge habitat.
- Keep rehabilitation areas free of dumped materials, concrete washout and spoil.
Rehabilitation actions: 2. Manage weeds, fire, water and predators
Control weeds before they alter ground cover or increase fuel loads. Use methods that do not contaminate soil or harm reptiles, invertebrates or retained vegetation.
Develop a fire regime with the land manager that retains shelter, hummock grasses, hollow logs and surface debris. Avoid frequent or broad, uniform fires.
Manage grazing, goat activity, rabbits, cats and foxes in coordination with the landholder and relevant pest program. Use fencing where it will protect regeneration and reduce trampling.
- Inspect rehabilitation after rain, drought and fire.
- Prevent erosion and retain natural soil profiles.
- Provide water only where it is part of an approved habitat design. Avoid creating permanent artificial water points that attract predators or alter the local community.
- Use low spill, shielded lighting and switch lights off when not required.
Rehabilitation actions: 3. Use suitable habitat features
Natural shelter is the preferred replacement feature for this species. Place local logs, stones, leaf litter and suitable surface debris in stable arrangements that retain access to loose soil.
Nest boxes, bat boxes, artificial nest sites and roost structures are not established replacement features for the Yellow-tailed Plain Slider. Do not install them as a substitute for natural habitat.
If an ecologist proposes an artificial feature for a specific project, obtain regulator approval first, use local materials and include a monitoring and removal plan.
- Do not create deep pits, open pipes or artificial cavities that can trap small reptiles.
- Keep replacement debris outside vehicle paths, drainage channels and firebreaks.
- Inspect features for heat, flooding, predation and accidental removal.
Rehabilitation actions: 4. Monitor rehabilitation
Monitor vegetation cover, soil stability, debris retention, grazing pressure, fire effects and predator activity. Include targeted searches for the Yellow-tailed Plain Slider where required by the approval or recovery program.
Use the same mapped sites and recording standards across monitoring visits so results can be compared over time. The species' low detectability means that several assessments may be needed before drawing conclusions.
Continue monitoring until performance criteria are met and the land manager accepts the site.
- Record search conditions, area covered, time spent and all detections or non-detections.
- Repair erosion, fencing and failed revegetation promptly.
- Review fire, weed, grazing and pest controls when habitat condition declines.
- Retain monitoring data with the project's environmental records and provide required reports to the relevant authority.
