Darling Range South-west Ctenotus (Ctenotus delli)

The Darling Range South-west Ctenotus is a small terrestrial skink associated with jarrah and marri woodland in south-west Western Australia. It may be encountered during clearing where dense understorey, grass trees, rocks and suitable soils remain, and is listed as Priority 4 by DBCA, so it needs monitoring and remains protected under Western Australia’s Biodiversity Conservation Act 2016.

Conservation status

Western Australia, WA Threatened and Priority Fauna List: Near threatened. Priority 4 (rare, near threatened) on the Western Australian priority fauna list. Priority species are not listed under the Biodiversity Conservation Act 2016 but should be considered in assessments.

Breeding season

The Darling Range South-west Ctenotus is poorly known, and species-specific breeding months have not been established. For clearing and construction planning in south-west Western Australia, use spring to early autumn as a precautionary breeding and young-rearing period, with timing shifting with local temperatures and seasonal conditions.

Breeding mode: Egg-laying is typical of Ctenotus skinks, but species-specific confirmation is not recorded.

Clutch size: Not recorded.

Incubation period: Not recorded.

Hatchling or juvenile dependency: Not recorded. Young skinks are expected to use nearby cover after hatching.

Age at maturity: Not recorded.

Breeding places: Not recorded. Dense vegetation, grass trees, rocks and sometimes burrows are recorded as shelter, but these sites are not confirmed breeding places.

Breeding frequency: Not recorded.

Timing may vary between years and sites, particularly with temperature, rainfall and the condition of the local understorey, so apply a precautionary approach in suitable habitat.

  • Mating and egg laying: Use September to January as a precautionary window for mating and egg laying in suitable woodland habitat.
  • Eggs and newly hatched young: Eggs and newly hatched young may be concealed in soil, litter or vegetation, so inspect suitable cover before clearing during the warmer months.
  • Surface activity and foraging: Surface activity is expected to increase in warmer weather, particularly where laterite, clay or sandy soils support jarrah and marri woodland with dense understorey.
  • Sheltering and reduced surface activity: During cooler conditions, individuals may spend more time beneath rocks, in dense vegetation, inside grass trees or in burrows.
  • Highest clearing risk: The highest seasonal risk is September to March, when clearing may affect mating adults, concealed eggs and young, although suitable habitat should be treated as occupied until checked.

Identification: Appearance and size

The Darling Range South-west Ctenotus is a terrestrial skink in the family Scincidae. Detailed field descriptions are limited, so positive identification should be confirmed by an experienced herpetologist where practical.

A reliable description of body pattern, colour and adult size is not available here. Treat small Ctenotus seen in suitable Darling Range habitat as potential records until they can be identified with confidence.

Group: Reptile, skink

Family: Scincidae

Size: No reliable field size is stated

Identification: Calls and similar species

This species is not known from a distinctive call or echolocation. No confirmed similar species or diagnostic comparison is available, so photographs and expert review are useful for unusual or conservation-significant records.

Identification: Field signs

Look for the animal itself moving through leaf litter, dense shrubs or open areas beside cover. Tracks, scats, nests, whitewash, stains and odour are not reliable signs reported for this species.

  • Search around rocks, logs, grass trees and the edges of dense vegetation.
  • Record the exact location, habitat, photographs and circumstances of any sighting.
  • Do not handle or relocate an animal unless authorised and trained procedures are in place.

Distribution: Australian range

The species is restricted to south-west Western Australia. Its documented range follows the Darling Range and reaches from the Darlington and Mundaring area southwards to near Collie.

Records are associated with the Swan and South West regions of Western Australia. The species has not been recorded in the Kimberley, Pilbara, Goldfields, Midwest, Wheatbelt, South Coast or Warren regions in the regional listing.

  • State: Western Australia.
  • Main range: Darling Range, from the Darlington and Mundaring area to near Collie.
  • The southern limit of the main documented range is near Collie.

Distribution: Site assessment

A site near the range boundary can still require careful assessment, particularly where suitable woodland and ground cover are present. Historical records may be sparse, and a nearby record should not be dismissed solely because recent detections are lacking.

  • Check DBCA records and local survey reports before clearing.
  • Map intact and partly degraded patches of suitable habitat.
  • Treat connected habitat and areas near known records as higher-priority survey areas.

Distribution: Overseas range

The Darling Range South-west Ctenotus is an Australian species. No overseas range is recognised.

Habitat: Vegetation and soils

Suitable habitat is mainly humid jarrah and marri woodland with a shrub-dominated understorey. Soils and landforms that support laterite, sand or clay, together with retained ground cover, should be checked during site planning.

Look for jarrah and marri woodland with dense or moderately dense shrubs. Lateritic and clay soils are characteristic, and suitable habitat may also occur on sandy substrates.

  • Jarrah and marri woodland.
  • Shrub-dominated understorey.
  • Laterite, clay or sand soils.
  • Intact leaf litter and ground cover.

Habitat: Landforms and site features

The species is associated with the Darling Range and may occur around rocky ground, including occasional granite outcrops. Habitat can be present in small retained patches if shelter and connected vegetation remain.

  • Lateritic rises and slopes.
  • Rocky ground and granite outcrops.
  • Vegetated edges adjoining woodland.
  • Patches connected to larger areas of native vegetation.

Habitat: Condition and connectivity

Highly degraded sites may have lower habitat value, but degraded edges can still retain shelter features. Avoid judging suitability from canopy cover alone, as the understorey, grass trees, rocks and leaf litter are particularly relevant.

  • Retain native understorey where possible.
  • Keep habitat patches connected during staging and access planning.
  • Inspect areas proposed for temporary laydown, tracks and stockpiles.

Foraging habitat: Where to look

Specific diet information is not established in the available profile. As a ground-dwelling Ctenotus, it should be managed as a small insect-eating or generalist skink unless local evidence indicates otherwise.

Search sunny and sheltered ground beside dense vegetation, grass trees, rocks, logs and leaf litter. Open patches next to cover may be used for movement or feeding, particularly where native ground cover remains.

  • Edges of shrub clumps and grass trees.
  • Leaf litter beneath jarrah and marri woodland.
  • Rock margins and fallen timber.
  • Open ground immediately beside retained cover.

Foraging habitat: Diet and feeding signs

The species’ diet and specific foraging signs are not documented. Do not rely on feeding remains, scats or tracks for identification.

  • Avoid disturbing cover while searching.
  • Record prey, feeding behaviour or repeated use of a location if observed.
  • Keep machinery, vehicle movements and personnel out of active search areas where practicable.

Foraging habitat: Survey approach

Daytime searches can include careful inspection of logs, rocks and leaf litter, together with transects through suitable habitat. Survey effort should be scaled to the amount and quality of habitat affected and to the likelihood of a local record.

  • Use experienced fauna personnel for searches and identification.
  • Search before clearing and again during staged clearing where habitat is retained nearby.
  • Coordinate searches with the clearing supervisor and spotter catcher.

Breeding habitat: Potential breeding habitat

Breeding habitat, breeding places and reproductive timing are poorly known for this species. Manage suitable ground habitat conservatively during clearing because breeding sites cannot be reliably identified from the available information.

Retained woodland with dense understorey, grass trees, rocks, leaf litter and suitable soils should be treated as potential breeding habitat. A burrow may provide shelter, but its use for breeding has not been confirmed.

  • Dense shrub cover.
  • Grass trees and their bases.
  • Rocky ground and deep leaf litter.
  • Burrows or cavities in suitable ground.

Breeding habitat: Breeding timing and signs

No dependable breeding months, clutch size or incubation information is available. There is also no described nest, maternity site or colony structure to guide a targeted exclusion period.

  • Report any eggs, juveniles, occupied burrows or repeated use of a shelter site.
  • Do not excavate or fill suspected burrows before assessment.
  • Seek advice from DBCA or a qualified herpetologist if breeding activity is suspected.

Breeding habitat: Clearing controls

Before clearing, inspect suitable habitat and mark features that can be retained. Use staged clearing and a trained spotter catcher where the risk of encountering reptiles is more than negligible.

  • Clear towards retained habitat where safe and appropriate.
  • Check vegetation, rocks, logs and grass tree bases before disturbance.
  • Stop work if an animal, eggs or a suspected breeding site is found.
  • Record and report any capture, relocation or mortality in accordance with project and regulatory requirements.

Sheltering habitat: Shelter features

The species shelters in dense vegetation, inside grass trees and beneath rocks. It is sometimes found in burrows, so ground disturbance can affect shelter even when the surface vegetation appears sparse.

Retain structural features that provide shade, cover and escape routes. Shelter is most likely to be valuable where several features occur together within native woodland or shrubland.

  • Dense shrubs and ground vegetation.
  • Grass trees, including bases and leaf skirts.
  • Rocks and rocky crevices.
  • Leaf litter, logs and possible burrows.

Sheltering habitat: Site inspection

Inspect proposed clearing areas in daylight before machinery enters. Look beneath movable rocks and logs only where this can be done safely, and replace cover immediately after inspection.

  • Use a systematic walkover of the clearing footprint.
  • Check edges, access tracks and temporary work areas as well as the main footprint.
  • Mark retained shelter features and no-go areas.
  • Keep fauna handling equipment and an appropriate release area available where required.

Sheltering habitat: During clearing

Use staged clearing and active supervision in suitable habitat. If a skink is found, pause nearby work and allow the animal to move into retained habitat where safe, or follow the project’s authorised fauna handling procedure.

  • Avoid crushing rocks, grass trees, logs and burrows with machinery.
  • Minimise unnecessary removal of understorey and leaf litter.
  • Maintain escape paths to connected native vegetation.
  • Document sightings, captures, injuries, deaths and relocations.

Threats: Clearing and fragmentation

No species-specific threats are established in the available profile. On development and land management sites, the main potential risks are loss of suitable habitat, removal of shelter and direct injury during clearing.

Removal of jarrah and marri woodland, shrub understorey and ground cover can reduce habitat. Fragmentation may isolate small habitat patches and remove movement routes between them.

  • Avoid clearing intact habitat where practicable.
  • Keep retained vegetation connected to larger native areas.
  • Include temporary works and access routes in the habitat impact assessment.
  • Rehabilitate disturbed areas with locally appropriate native vegetation and ground cover.

Threats: Loss of shelter and ground features

Rocks, grass trees, logs, leaf litter and burrows may provide important shelter. Their removal or burial can reduce habitat quality even where some canopy remains.

  • Map and retain shelter features inside and beside the clearing footprint.
  • Do not use habitat features as informal fill or stockpile material.
  • Limit unnecessary soil stripping and ground compaction.
  • Inspect suspected burrows before excavation or grading.

Threats: Direct mortality during works

Animals may be crushed, buried or injured by clearing, earthworks, vehicles and material handling. The risk increases when machinery works through dense vegetation or rocky ground.

  • Use a qualified fauna spotter catcher for higher-risk clearing.
  • Clear in stages and pause when fauna is detected.
  • Apply low-speed vehicle controls and keep personnel alert around habitat edges.
  • Record and report incidents so controls can be improved.

Threats: Fire, weeds and altered ground cover

Changed fire regimes, weed invasion and loss of native understorey may reduce shelter and prey resources. Manage these pressures in retained habitat and rehabilitation areas.

  • Prevent weed spread on vehicles and machinery.
  • Protect retained vegetation from accidental fire and hot works.
  • Avoid unnecessary slashing of native understorey.
  • Monitor retained and rehabilitated habitat as part of the project’s environmental management program.

Survey methodology: 1. Desktop assessment

The Darling Range South-west Ctenotus is a poorly known, ground-dwelling skink. Survey effort should focus on suitable jarrah and marri woodland, shrub-dominated understorey, laterite, sand or clay soils, and sheltered ground features.

Check recent fauna records, habitat mapping and aerial imagery before planning works. Give particular attention to the Darling Range between the Darlington and Mundaring area and near Collie, including the Swan and South West regions.

Map retained woodland, shrub cover, grass trees, rocks, logs, leaf litter, burrows, laterite, clay and granite outcrops. Treat connected or less disturbed habitat near known records as higher risk.

  • Confirm the current Western Australian listing, approvals and land tenure requirements before survey or clearing.
  • Check whether the site supports suitable habitat, even where the ground layer is partly degraded.
  • Use a qualified zoologist or herpetologist to review the survey design and identify likely lookalike skinks.

Survey methodology: 2. Daytime habitat searches

Search during the day when the ground surface is warm and conditions are dry enough for reptiles to be active. Avoid relying on a cold, wet or heavily overcast visit to rule out presence.

Walk systematic transects through suitable habitat and inspect logs, rocks, leaf litter, dense vegetation, grass trees and the entrances of potential burrows. Check the edges of clearings and retained vegetation as well as undisturbed ground.

Use binoculars for basking animals and record direct observations, tracks, burrows, shelter sites and other evidence. Do not dismantle shelters unless this is authorised and necessary.

  • Record the date, start and finish time, weather, recent rainfall, temperature conditions, observers, transect locations and search method.
  • Photograph habitat and diagnostic features where this can be done without disturbing an animal.
  • Treat a single historical record or a nearby record as a reason for targeted survey, not as evidence that the species is absent.

Survey methodology: 3. Targeted detection and effort

Set the number and length of transects, repeat visits and any trapping effort according to the amount of suitable habitat, proposed clearing and the consequences of a missed detection. There is no established species-specific effort or detection probability for this skink.

Where daytime searches do not provide adequate confidence, a suitably experienced herpetologist may recommend authorised pitfall or funnel trapping, cover objects or other methods. Use these only under the relevant animal ethics, licence and welfare requirements.

Check traps and other devices at the frequency required by the approval, protect them from heat and weather, and provide suitable shelter and moisture.

  • Do not claim absence from a brief reconnaissance survey in suitable habitat.
  • Stop or revise the method if animals show heat stress, injury or repeated disturbance.
  • Record trap locations, trap nights, checking times, captures, releases, bycatch and weather.

Survey methodology: 4. Interpreting results

Map every record with coordinates and describe the substrate, vegetation, shelter feature and condition of the site. Record whether the animal was basking, moving, sheltering or captured.

Use the precautionary approach where identification is uncertain, habitat is suitable or a record is close to the disturbance footprint. Seek expert confirmation from a qualified reptile ecologist.

The species has no documented migration schedule or breeding season that can be used to define a safe survey window. Plan repeat surveys where seasonal conditions or habitat risk could materially affect detection.

  • Provide the project manager with a habitat map, survey limitations, confidence in the result and a clear recommendation for clearing.
  • Retain photographs, field notes, specimen or tissue records where legally collected, and all negative-survey data.
  • Report records through the relevant Western Australian biodiversity recording system and project approval channels.

Before habitat disturbance: 1. Avoidance and approvals

Avoiding suitable habitat is the best protection for this Priority 4 species. Plan clearing around confirmed records, retained shelter habitat and the level of uncertainty in the survey result.

Retain jarrah and marri woodland, shrub-dominated understorey, grass trees, rock cover, logs, leaf litter and natural burrows wherever practicable. Keep clearing footprints narrow and use existing access routes.

Confirm whether the proposal requires an environmental approval, clearing approval, referral under the Environment Protection and Biodiversity Conservation Act 1999, or a state fauna authorisation. The species is recorded as Western Australian Priority 4, with no national listing shown in the current assessment information.

Queensland projects must check the applicable protected wildlife requirements and whether disturbance to a breeding place requires a species management program. Obtain all required state permits before capture, handling, trapping or relocation.

  • Ask the approvals specialist to confirm requirements for the actual state, land tenure and action.
  • Do not treat Priority 4 as an exemption from Western Australian fauna protection.
  • Include the species in the construction environmental management plan where suitable habitat or nearby records occur.

Before habitat disturbance: 2. Pre-clearance survey and marking

Complete a targeted pre-clearance inspection shortly before works, after the main habitat survey and before machinery enters the area. Search the approved disturbance footprint and adjacent retained habitat for animals, shelters and burrows.

Mark no-go areas, retained rocks, grass trees, logs, dense vegetation and identified shelter features on the ground. Fence or flag exclusion areas so machinery operators can see them clearly.

Have the fauna spotter catcher confirm that the survey conditions are suitable and that the work area has been checked. Increase survey effort if conditions are unsuitable or if new habitat is exposed.

  • Brief the crew on the species, its appearance once confirmed by an ecologist, likely shelters and the stop-work process.
  • Check beneath or around materials that will be moved, without crushing, dragging or sealing possible shelter sites.
  • Keep vehicles, spoil, materials and laydown areas outside retained habitat and exclusion zones.

Before habitat disturbance: 3. Timing and buffers

No breeding months or migration period are established for this species. Do not assume that any season is risk-free. Schedule works when reptiles are detectable and conditions allow an effective pre-clearance inspection, subject to approvals and weather.

Set buffers around records, suitable shelter and retained habitat through the project ecologist and approval conditions. There is no species-specific buffer distance available for this skink.

Increase the buffer or defer clearing where an animal cannot be located, a burrow or shelter may be occupied, or clearing would isolate a retained habitat patch.

  • Use physical exclusion fencing where a no-go area must remain undisturbed.
  • Inspect and maintain fencing after rain, vehicle movements and changes to the work area.
  • Record the basis for every buffer and obtain written sign-off before reducing or removing one.

Before habitat disturbance: 4. Crew readiness

Nominate a fauna spotter catcher with authority to stop work. Make that authority clear to supervisors, machine operators and subcontractors before clearing begins.

Use only trained and authorised personnel for capture, handling, identification and relocation. Prepare clean containers, shade, gloves where appropriate, a field notebook, camera and a safe temporary holding area before work starts.

Keep the work area orderly. Remove rubbish, open pipes, uncovered trenches and other artificial traps or cover them whenever they are not being actively used.

  • Include emergency contacts, the nearest wildlife carer or veterinarian, and the approval holder in the site induction.
  • Tell workers not to chase, touch, feed or kill reptiles.
  • Require immediate notification of any suspected threatened or priority fauna record, injury or breach of an exclusion zone.

During habitat disturbance: 1. Sequential clearing

Clear in a controlled sequence from the disturbed edge towards retained habitat. Stop work whenever an animal or possible shelter site cannot be safely managed under the approved procedure.

Clear low vegetation and surface materials in stages, allowing animals an opportunity to move into retained habitat where the ecologist considers that safe and appropriate. Work towards a defined escape area rather than surrounding an animal.

Use machinery at low speed and avoid crushing rocks, grass trees, logs, dense shrubs and burrow entrances before they have been inspected.

Do not burn, poison, flood or bury habitat as a substitute for a fauna inspection.

  • Keep the fauna spotter catcher ahead of machinery and within clear communication range.
  • Pause work while the spotter catcher checks newly exposed ground, debris and shelters.
  • Maintain the agreed exclusion areas throughout the shift, including during clean-up and grading.

During habitat disturbance: 2. Animal found

Stop the relevant activity and establish a quiet exclusion zone if a Darling Range South-west Ctenotus is found. Allow the spotter catcher or other authorised person to assess whether it can move naturally into retained habitat.

Handle the animal only when necessary for safety, identification, approved relocation or veterinary care. Use appropriate clean equipment and minimise holding time, heat and physical restraint.

Release a healthy animal only at an approved nearby location with suitable shelter and habitat, and only where the permit or management plan allows it. Do not move it across roads, into unsuitable cleared ground or into an unrelated population.

  • Photograph the animal and record its location before capture where this can be done safely.
  • Record the release location, habitat, time in the container, condition and any identification uncertainty.
  • Resume work only after the spotter catcher gives clearance.

During habitat disturbance: 3. Burrows and breeding places

No breeding place type or breeding timing is established for this species. Treat an occupied burrow, shelter or suspected breeding site as sensitive until an ecologist and the approval holder decide how it will be managed.

Do not excavate, fill, seal or drive machinery over a suspected active breeding place. Maintain the agreed exclusion zone and seek advice before disturbing it.

If a colony, concentration of animals or other important site is found, stop work in that area and notify the project ecologist and relevant regulator where required.

  • Photograph and map the feature without inserting tools or hands.
  • Check approval conditions for any required inspection, permit variation, relocation protocol or reporting.
  • Document the decision, decision maker, controls and time that work recommenced.

During habitat disturbance: 4. Injury and incident response

Place an injured animal in a secure, ventilated, shaded container lined with a clean material. Keep it quiet and do not offer food, water or medication unless directed by a veterinarian or wildlife carer.

Contact the nominated wildlife carer, veterinarian or fauna specialist promptly. Follow the approval holder's chain of custody and reporting procedure.

Report deaths, injuries, unauthorised handling, escaped animals, damaged exclusion fencing and clearing outside the approved footprint.

  • Record the animal's condition, injury, location, time, action taken and destination.
  • Do not release an injured animal without veterinary or fauna specialist advice.
  • Stop work if the incident indicates that the control measures are not working.

After habitat disturbance: 1. Post-clearance checks

Close-out checks should confirm that no animals remain trapped in the work area and that all fauna incidents have been dealt with properly. Use the results to improve controls for the next clearing stage or project area.

Inspect the cleared footprint after each clearing stage and before final grading, trenching or backfilling. Check debris piles, open trenches, pipes, drains, stockpiles and remaining vegetation for trapped or sheltering reptiles.

Remove or cover artificial traps at the end of each shift and after storms. Keep access to retained habitat clear for animals that have moved out of the work area.

Have the fauna spotter catcher sign off the area before machinery changes from clearing to construction.

  • Record the inspection date, area checked, people involved, weather, findings and corrective actions.
  • Reinspect any area where habitat was cleared in stages or where animals were previously detected.
  • Continue checks while ground disturbance creates new holes, piles or exposed shelter.

After habitat disturbance: 2. Reporting and records

Prepare a fauna close-out record for each work area. Include survey results, animal records, relocations, injuries, deaths, stop-work events, permit conditions and any non-compliance.

Submit records to the project ecologist, approval holder and relevant regulator or database where required. Update the site habitat map with retained areas and final clearing limits.

Retain photographs, coordinates, field sheets, handling records and veterinary or wildlife carer documents in the project environmental file.

  • Report a suspected new population or important concentration through the appropriate Western Australian biodiversity reporting pathway.
  • Record negative results as well as captures and incidents.
  • Compare actual clearing with the approved footprint and investigate any discrepancy promptly.

After habitat disturbance: 3. Relocated animals and follow-up

Check relocated animals in accordance with the approved relocation plan. Use the minimum follow-up needed to confirm that release sites remain intact and that animals were not released into active works or unsuitable habitat.

Do not repeatedly recapture or disturb healthy animals solely for observation. If monitoring is required, use methods approved by the project ecologist and relevant authority.

Review whether relocation was necessary, whether the release habitat was suitable and whether any animal showed injury or abnormal condition.

  • Map release sites and retain their habitat description in the project records.
  • Report any recaptured, injured or dead relocated animal through the incident process.
  • Use the results to refine avoidance, survey and clearing controls for later stages.

After habitat disturbance: 4. Incident review

Review every stop-work event, injury, death, suspected breeding place and escape from an exclusion area. Include the spotter catcher, supervisor, ecologist and project manager in the review.

Identify whether the cause was poor timing, inadequate survey, unclear marking, machinery movement, unsuitable habitat assumptions or a failure to follow the induction.

Update the construction environmental management plan, maps, inductions and work method before the next clearing stage.

  • Keep corrective actions specific, assigned and dated.
  • Do not restart a recurring activity until the revised control has been approved.
  • Escalate repeated incidents to the approval holder and regulator where required.

Rehabilitation actions: 1. Habitat restoration

Rehabilitation should rebuild the sheltered ground layer used by this skink and reconnect retained woodland wherever possible. The species is poorly known, so restoration should favour natural habitat features rather than untested artificial structures.

Restore jarrah and marri woodland structure with a dense native shrub understorey on locally appropriate laterite, sand or clay soils. Retain or reinstate grass trees, logs, rocks, leaf litter and natural ground cover.

Reconnect retained vegetation patches where practical and avoid creating narrow, hot edges between woodland and cleared ground. Use local provenance plants and protect newly restored areas from vehicles and compaction.

Do not import rocks, soil or woody material from areas that could introduce weeds, pathogens or unsuitable fauna habitat.

  • Place natural logs and rocks in stable locations that provide shade and shelter.
  • Leave leaf litter and low vegetation in rehabilitation areas rather than maintaining bare ground.
  • Protect rehabilitation from grazing, repeated slashing, fire impacts and unauthorised access.

Rehabilitation actions: 2. Artificial structures

There is no established requirement for nest boxes, bat boxes, artificial nests or roost structures for this species. These structures are not a substitute for retaining natural shelter.

If the project ecologist recommends supplementary cover, use locally sourced logs, rocks or other natural materials that resemble the site's existing shelter. Install them without trapping animals or obstructing movement.

Do not install bat boxes, nest boxes or roost structures unless they are intended for another confirmed species and have a separate ecological justification.

  • Record the location, design, materials and installation date of any supplementary shelter.
  • Inspect artificial cover only under an approved monitoring method and avoid unnecessary disturbance.
  • Remove or modify structures that collect heat, water, rubbish or predators.

Rehabilitation actions: 3. Weeds, water and lighting

Control weeds before they replace the native shrub layer or alter ground shelter. Use methods that do not expose animals to toxic residues, crushing or prolonged bare ground.

Manage drainage so rehabilitation is not eroded, waterlogged or artificially channelled through shelter habitat. This skink has no documented dependence on constructed water points, so do not add water features unless needed for broader habitat outcomes.

Use the minimum lighting needed for safety and direct it away from retained and rehabilitated vegetation. Avoid bright, continuous lighting around shelter areas.

  • Inspect weed control areas for reptiles before mowing, spraying or slashing.
  • Keep chemicals, wash-down water and sediment out of retained habitat.
  • Use fauna-sensitive lighting and shield fittings where construction lighting is unavoidable.

Rehabilitation actions: 4. Long-term monitoring

Monitor rehabilitation for survival of native plants, recovery of shrub cover, retention of logs and rocks, weed invasion, erosion and use by reptiles. Set the duration and frequency through the approval conditions and project ecologist.

Use repeat daytime searches in suitable weather and the same mapped areas where comparisons are needed. Record effort as well as detections so results can be interpreted consistently.

Because abundance, breeding biology and population responses are poorly known, treat habitat condition and confirmed records as the main indicators unless a formal monitoring design is approved.

  • Photograph fixed points and map rehabilitation condition over time.
  • Record direct sightings, shelter use, mortality, predator evidence and any new threats.
  • Review monitoring results with the land manager and adjust weed control, access, shelter placement or protection measures when needed.
