Chillagoe Litter-skink (Lygisaurus rococo)

The Chillagoe litter-skink is a small Queensland endemic skink known from the Chillagoe region and nearby parts of Far North Queensland. It may occur in tropical woodland and rocky country, so clearing and construction works around outcrops, boulders and ground litter should be planned carefully. It is listed as near threatened in Queensland and is protected wildlife under Queensland law.

Conservation status

Queensland, Nature Conservation Act 1992: Near threatened.

Breeding season

The Chillagoe litter-skink is poorly known, and species-specific breeding months have not been recorded. For planning in Queensland, use a precautionary pattern of greater activity and likely breeding from October to April, with local variation between years and sites.

Breeding mode: Not recorded.

Clutch or litter size: Not recorded.

Incubation or gestation: Not recorded.

Fledging or weaning: Not recorded.

Age at maturity: Not recorded.

Nest or shelter sites: Not recorded. Avoid disturbing potential shelters under rocks, logs, leaf litter and other ground cover until a site assessment is complete.

Breeding frequency: Not recorded.

Timing may shift between years and regions with rainfall, temperature and local habitat conditions, so use pre-clearing searches and fauna spotter catcher supervision where suitable habitat is present.

  • Likely breeding activity, Queensland: Use October to December as a precautionary breeding window because the species-specific breeding season is unknown.
  • Likely breeding activity, continued: January to April may include breeding or recently produced young, particularly after favourable warm and wet conditions.
  • Likely young and dispersing juveniles: Treat October to April as a period when eggs, hatchlings or dependent juveniles may be present, although the species-specific reproductive stages are not recorded.
  • General surface activity: Activity is likely to be greater in warmer months, but suitable weather may allow activity throughout the year in tropical Queensland.
  • Shelter use and local movement: Assume animals may be present in suitable ground cover and rocky habitat year-round, including during clearing or construction works.
  • Highest clearing risk: The highest precautionary risk is October to April, when breeding, young and greater activity may overlap, but near threatened habitat should be checked before disturbance in every month.

Identification: Appearance and field identification

The Chillagoe litter-skink is a poorly known member of the skink family. Detailed identification information, including body size, colour pattern and calls, is limited, so fauna spotter catchers should use a qualified reptile ecologist when identification is uncertain.

Confirm records against current Queensland taxonomic and wildlife databases before works begin. Do not rely on a photograph or a broad description alone where other small skinks may be present.

Record clear photographs of the head, body, tail, limbs and dorsal pattern where this can be done without handling the animal unnecessarily.

Scientific name: Lygisaurus rococo

Family: Scincidae

  • Note the exact location and habitat feature where the animal was found.
  • Record whether it was beneath litter, beside a rock, under timber or moving through low vegetation.
  • Avoid turning over rocks or timber repeatedly, as these may provide shelter for reptiles.

Identification: Size, calls and similar species

A verified adult size, weight, call description and diagnostic comparison with similar species are not established in the available profile. The species should be treated as a small terrestrial skink for field planning, rather than identified by size alone.

Skinks generally do not use echolocation, and no distinctive call is documented for this species. Identification should be based on morphology, photographs, location and habitat together.

  • Seek expert confirmation for unfamiliar individuals.
  • Retain a photographic voucher and location data for unusual records.
  • Do not release a captured reptile at a different site without an approved method and suitable authorisation.

Identification: Field signs

No species-specific nests, droppings, odour, stains or other field signs are documented. Direct sightings are therefore more useful than indirect signs.

Search records should include the microhabitat and any cover object associated with the animal. This information can help identify repeat-use shelter areas during site supervision.

  • Photograph the animal before moving it where practicable.
  • Mark the find location on the project plan or approved fauna register.
  • Report injured, trapped or repeatedly encountered animals to the project environmental representative.

Distribution: Range in Australia

The Chillagoe litter-skink is a Queensland endemic. Records are concentrated in the Chillagoe area and Far North Queensland, but available occurrence mapping may not show the full local distribution.

The species is recorded from Queensland and is classified as naturally occurring only in that state. It is associated with the broader Chillagoe and Far North Queensland region in the available regional records.

No overseas range is recorded.

State: Queensland

Regional context: Chillagoe and Far North Queensland

Overseas range: None recorded

  • Treat suitable habitat as potentially occupied even where no database record is mapped.
  • Check current WildNet records and project specific information before clearing or ground disturbance.
  • Use local records as an indicator of possible presence, not as proof that unsurveyed areas are unoccupied.

Distribution: Interpreting records

Queensland occurrence records can have location uncertainty and may include records close to, rather than inside, a mapped project area. A missing record does not demonstrate absence.

Older records should still be considered during planning because the species may be difficult to detect and the local dataset is subject to ongoing revision.

  • Review the date, precision and habitat context of each record.
  • Confirm whether a record falls within the proposed disturbance footprint or an adjacent habitat patch.
  • Document negative survey results with methods, dates, weather and search effort.

Habitat: Vegetation and landform

Species specific habitat information is limited. For site planning, give particular attention to tropical woodland and rocky landscapes in the Chillagoe area, especially places with granite outcrops and boulders that may provide restricted habitat for reptiles.

Chillagoe Mungana Caves National Park contains tropical woodlands and granite outcrops. Outcrops with boulders are a useful habitat feature to retain and inspect, although the available park information does not confirm that every such feature is occupied by the Chillagoe litter-skink.

Prioritise habitat assessment where woodland meets rocky ground, low vegetation and accumulated leaf litter.

  • Tropical woodland with an intact ground layer.
  • Granite outcrops, boulder fields and rocky margins.
  • Patches of leaf litter, fallen timber and low cover near rocks.
  • Connections between rocky habitat patches and surrounding woodland.

Habitat: Site assessment

Before clearing, walk the proposed footprint and map rocky features, ground cover and areas of undisturbed litter. Include temporary access tracks, laydown areas, spoil locations and work compounds in the assessment.

Avoid assuming that highly modified ground is unsuitable without a field check. Small terrestrial skinks can be overlooked in disturbed margins and beneath cover objects.

  • Mark outcrops and boulder clusters on construction drawings.
  • Keep machinery and materials away from retained rocky habitat where practicable.
  • Use a staged inspection when cover will be removed or ground will be excavated.
  • Have a fauna spotter catcher present for clearing in potential habitat.

Habitat: Habitat condition

Retain connected patches of woodland and rocky ground wherever the project allows. Limit unnecessary removal of leaf litter, fallen timber and loose surface cover.

Do not move rocks or timber from retained habitat into cleared areas unless this forms part of an approved ecological management method.

  • Control vehicle movement to defined work areas.
  • Prevent sediment, rubble and construction waste from filling rock crevices or litter layers.
  • Rehabilitate disturbed edges with locally appropriate native vegetation and ground cover.

Foraging habitat: Likely foraging areas

The diet and detailed foraging habitat of the Chillagoe litter-skink are not documented in the available profile. As a terrestrial skink, it should be managed as a ground active reptile that may forage through litter, low vegetation and rocky cover.

Inspect ground litter, low vegetation, rock margins and fallen timber for potential foraging habitat. These features can support small invertebrate prey and provide cover while the animal moves.

Do not remove ground cover ahead of clearing without a planned fauna management approach.

  • Leaf litter beneath woodland canopy.
  • Low plants and grass at the edge of rocks and boulders.
  • Crevices, rock margins and shaded ground.
  • Fallen timber and other natural surface cover.

Foraging habitat: Foraging behaviour and diet

A species specific diet, activity pattern and seasonal foraging period are not confirmed. Avoid making decisions about habitat value from a single short search, particularly in hot, dry or windy conditions.

Use experienced surveyors who can inspect cover carefully and recognise small skinks before machinery enters the area.

  • Search during conditions suitable for reptile activity where practicable.
  • Inspect both the proposed footprint and immediately adjoining retained habitat.
  • Record weather, time, ground temperature if measured, and search conditions.

Foraging habitat: Worksite controls

Keep lighting, noise, vehicle movements and pedestrian traffic away from retained habitat where practicable. Prevent spoil, concrete washout, chemicals and rubbish from entering rocky or litter rich areas.

Use designated access routes so repeated traffic does not crush surface cover or isolate habitat patches.

  • Fence or clearly mark no go areas before works start.
  • Cover or secure trenches and other excavations when unattended.
  • Check excavations and stored materials for trapped fauna.
  • Stop work and seek advice if a suspected Chillagoe litter-skink is found in the active work area.

Breeding habitat: Known breeding information

Breeding biology and breeding places are not documented in the available profile. Until local information is available, treat suitable ground cover, rocks, litter and connected woodland as potentially relevant to breeding and juvenile shelter.

No confirmed breeding season, clutch or litter size, incubation period, maturity age or specific breeding structure is recorded for this species.

Do not disturb potential breeding or shelter features simply because no nest is visible. Small skinks may use concealed sites that are difficult to detect.

Breeding season: Not established in the available profile

Breeding place: No specific place type is confirmed

Clutch or litter size: Not established

  • Seek advice from the project ecologist before removing rocks, timber or deep litter.
  • Record any juveniles, gravid females or repeated sightings separately from general observations.
  • Add breeding observations to the fauna register and current species database where appropriate.

Breeding habitat: Breeding place protection

Queensland near threatened animals are protected wildlife. Tampering with a breeding place requires a species management program under Queensland requirements.

Where works could affect a suspected breeding place, stop the relevant activity and obtain direction from the project ecologist and the Queensland regulator before proceeding.

  • Retain suspected breeding and shelter features until assessed.
  • Do not collect eggs, young or adults unless authorised and necessary for animal welfare.
  • Do not relocate rocks or other potential breeding features without approval.

Breeding habitat: Clearing practice

Use a staged clearing method in potential habitat. First mark the limits of approved disturbance, then inspect the area with a fauna spotter catcher before vegetation and surface cover are removed.

Keep cleared habitat and retained habitat clearly separated. Avoid creating piles of rocks, timber or litter that could trap animals or later require unplanned removal.

  • Clear from the less disturbed edge towards retained habitat where practicable.
  • Check exposed ground, rock crevices, timber and litter during each clearing stage.
  • Maintain an incident and animal handling record for all fauna interactions.

Sheltering habitat: Features to inspect

No species specific sheltering site has been confirmed. Rocky ground, boulders, leaf litter, fallen timber and low vegetation should nevertheless be treated as potential shelter features during site inspections and clearing.

Look beneath and around natural surface cover without excessive disturbance. Focus on shaded sides of boulders, rock crevices, litter edges and the interface between rocks and woodland ground cover.

Inspect retained habitat beside the footprint as well as the area to be cleared, because animals may move into adjoining cover during works.

  • Granite outcrops and boulder clusters.
  • Rock crevices and gaps beneath loose rocks.
  • Leaf litter and fallen timber.
  • Low vegetation beside rocky ground.

Sheltering habitat: Construction risks

Open trenches, pipes, pits, stored materials and spoil can trap or injure small reptiles. Rocks and timber placed in access routes can remove shelter and create avoidable fauna hazards.

Inspect artificial cover and excavations regularly during active works, using the project's approved fauna handling procedure.

  • Use fauna friendly trench controls where practicable.
  • Keep excavations covered or provide safe escape points when unattended.
  • Store materials off the ground where practicable and inspect them before movement.
  • Remove waste and construction materials from retained habitat.

Sheltering habitat: Handling and release

If an animal is found, pause work in the immediate area and allow the fauna spotter catcher to assess it. Handling, temporary containment and release must follow the approved project procedure and Queensland requirements.

Release should only occur at an approved suitable location close to the capture site, unless a regulator or qualified ecologist directs otherwise.

  • Minimise handling time and heat exposure.
  • Keep the animal shaded and secure while advice is obtained.
  • Record the capture point, condition, action taken and release location.
  • Escalate suspected injury or repeated captures to the project ecologist.

Threats: Clearing and fragmentation

The Chillagoe litter-skink is near threatened in Queensland, so avoidable loss of habitat and disturbance should be reduced at every project stage. Species specific threats are not well documented, but several common clearing and land management pressures are relevant to planning.

Removing woodland, rocky outcrops, boulders and ground cover can reduce available habitat. Roads, tracks and work areas can also divide small habitat patches and increase vehicle risk.

Keep the disturbance footprint as small as practicable and retain links between rocky and woodland habitat.

  • Avoid unnecessary removal of outcrops and boulders.
  • Use existing disturbed access routes where suitable.
  • Keep temporary works within approved limits.
  • Rehabilitate redundant work areas promptly.

Threats: Fire and ground cover loss

The park management statement identifies inappropriate fire regimes as a general threat to regional ecosystems. Frequent or intense fire can alter woodland structure and remove litter, fallen timber and low cover used by terrestrial reptiles.

Apply the approved fire management plan and avoid unplanned burning or clearing of refuge features.

  • Protect retained litter and fallen timber from unnecessary removal.
  • Plan fuel reduction work around mapped rocky habitat.
  • Monitor recovery of ground cover after fire or major disturbance.

Threats: Weeds and habitat degradation

Pest plants can change woodland structure and ground conditions, and dense infestations may affect movement and shelter. Rubber vine, Chinee apple and Indian couch are identified as management issues in the Chillagoe Mungana Caves area.

Control weeds using methods that avoid unnecessary disturbance to rocks, litter and retained native vegetation.

  • Map weed infestations before treatment.
  • Prevent soil and seed movement between habitat patches.
  • Use low impact access and follow hygiene procedures for machinery.
  • Inspect treated areas for erosion and loss of ground cover.

Threats: Construction disturbance and direct mortality

Vehicles, machinery, trenches, material storage and uncontrolled clearing can kill or injure small skinks. Disturbance can also displace animals into less suitable or unsafe areas.

Use a site specific fauna management plan, spotter catcher supervision and clear stop work triggers for suspected individuals or breeding places.

  • Brief all workers before clearing starts.
  • Install exclusion fencing around retained habitat and no go areas.
  • Check excavations and stored materials each workday.
  • Report records promptly so controls can be adjusted.

Survey methodology: 1. Desktop assessment

The Chillagoe litter-skink is a poorly known Queensland endemic and can be difficult to detect. Use several complementary methods, with effort increased where suitable ground cover, rocky woodland or leaf litter will be disturbed.

Check WildNet records, recent ecological reports, regional mapping and park management information before planning works.

Map potential habitat and all records within and near the work area. Treat mapped records as indicative because location accuracy and record age vary.

  • Review records from the Chillagoe and surrounding localities.
  • Check whether the proposal affects protected areas, mapped habitat, rocky outcrops, boulder fields, woodland, dense leaf litter or other likely ground shelter.
  • Confirm the current Queensland listing and any permit, approval or species management program requirements.

Survey methodology: 2. Targeted field searches

Search during suitable weather when small skinks are most likely to be active. Warm, settled conditions with limited wind are generally preferable. Avoid relying on a single visit after cold, prolonged rain or very dry conditions.

Use a combination of visual searching and careful searches of ground cover. The species has no published survey protocol in the available profile, so survey design should be set by a suitably qualified herpetologist.

  • Walk slowly through all areas proposed for clearing and inspect leaf litter, fallen timber, loose bark, rocks and other surface cover where present.
  • Search edges as well as the centre of habitat patches, including areas around tracks, stockpiles and proposed access routes.
  • Use active searches during daylight and consider repeat visits under different suitable conditions.
  • Use pitfall traps, funnel traps or other live trapping only where approved, ethically justified and supervised by appropriately experienced personnel.

Survey methodology: 3. Survey effort and seasonal coverage

Set the number of visits and search effort according to the size and condition of the site, the amount of habitat to be cleared, the quality of existing records and the consequences of a missed detection. Do not assume that one negative survey demonstrates absence.

Breeding timing and seasonal movements are not established in the available species profile. Schedule additional surveys if works may affect suspected breeding places or if local records indicate seasonal activity.

  • Allow enough time for a careful search of every disturbance footprint, including temporary work areas.
  • Repeat surveys where initial conditions are unsuitable or where the species is a realistic possibility but has not been detected.
  • Use qualified ecologists to document and justify the survey design in the ecological assessment.

Survey methodology: 4. Records and evidence

Record enough information to support decisions, approvals and later monitoring. Photograph animals and habitat where this can be done without causing harm.

Submit significant records to the relevant Queensland biodiversity database or authority, subject to current data requirements.

  • Record date, time, observer, weather, search method, duration, area searched and detection conditions.
  • Map each detection with coordinates and record whether the animal was active, sheltering, injured or associated with a potential breeding place.
  • Describe ground cover, rocks, fallen timber, leaf litter, vegetation condition and the proposed disturbance at each detection.
  • Keep trapping, handling, release and mortality records where those methods are authorised.

Before habitat disturbance: 1. Avoidance and approvals

Plan the work around avoidance first. The Chillagoe litter-skink is listed as near threatened in Queensland, so proposed clearing should be assessed conservatively and supported by appropriately qualified ecological advice.

Retain known and potential habitat wherever practicable. Reduce the disturbance footprint, use existing access routes and keep machinery out of retained habitat.

Confirm approvals before work starts. The species is not listed under the EPBC Act in the available profile, but an EPBC referral may still be needed if other matters of national environmental significance could be affected.

In Queensland, confirm whether a protected wildlife permit, authority or species management program is required under the Nature Conservation Act 1992. Tampering with a breeding place of a near threatened animal requires a species management program.

  • Obtain written environmental approval for the final clearing footprint.
  • Have the fauna spotter catcher and ecologist check permit conditions before mobilisation.
  • Stop planning at the permit stage if a potential breeding place may be disturbed and the required authority is not in place.
  • Use the current Queensland legislation, permit conditions and agency advice where requirements have changed.

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

Complete a targeted pre-clearance survey close enough to the clearing date that conditions and records remain relevant. Search the full footprint, including temporary disturbance areas.

Mark retained habitat, exclusion areas, access limits and any potential breeding places before machinery arrives.

  • Have a qualified ecologist inspect leaf litter, rocks, logs, bark and other ground shelter throughout the footprint.
  • Flag all confirmed records, potential breeding places and habitat to be retained.
  • Use high visibility fencing, bunting or equivalent barriers that machinery operators can see.
  • Check exclusion fencing daily during the clearing period and repair damage promptly.

Before habitat disturbance: 3. Timing, buffers and exclusion

Breeding timing and movement patterns are not established for this species. Avoid disturbing suspected breeding places until an ecologist has assessed them and the relevant Queensland requirements have been met.

Set buffers around records, potential breeding places and retained habitat using the ecological assessment, permit conditions and site risk. Do not apply an arbitrary buffer where the habitat boundary or breeding place has not been assessed.

  • Schedule clearing outside periods identified by the project ecologist as unsuitable, if local evidence identifies such periods.
  • Retain connected ground cover and shelter around habitat that will remain.
  • Prevent vehicle access, storage, lighting spill and soil disturbance within exclusion areas.
  • Obtain written approval before reducing or moving any exclusion area.

Before habitat disturbance: 4. Induction and equipment

Give every worker a short site induction before clearing. The induction should explain the species, its Queensland near threatened status, exclusion areas and the stop-work process.

Prepare the fauna team before vegetation removal begins.

  • Provide photographs or a field identification sheet for the Chillagoe litter-skink.
  • Tell workers not to handle reptiles or move rocks, logs or other cover outside the approved clearing sequence.
  • Place the fauna spotter catcher's contact details at the site office and in machinery cabins.
  • Prepare ventilated containers, soft capture equipment, gloves suitable for reptile handling and a first aid and wildlife contact plan.

During habitat disturbance: 1. Sequential clearing

Clear in a controlled sequence and give the fauna spotter catcher authority to stop work. All animal handling must be humane, documented and undertaken only by people authorised and competent to do so.

Clear from the least disturbed edge towards retained habitat where the site layout allows. Use slow, staged removal so animals have an opportunity to move into approved retained areas.

Keep the fauna spotter catcher ahead of machinery and maintain a clear view of the active work face.

  • Remove non habitat obstacles and loose material only after the spotter catcher has searched them.
  • Lift or roll cover carefully, rather than crushing or dragging it, where the clearing method allows.
  • Pause machinery while the spotter catcher checks concealed ground cover, rock piles, logs and leaf litter.
  • Do not burn, bury or chip material until it has been checked as required by the site approval.

During habitat disturbance: 2. Stop work and animal handling

Give the fauna spotter catcher authority to stop work immediately when an animal, potential breeding place or unsafe condition is found. The site supervisor must support that direction.

Only authorised and trained personnel may capture, handle, contain or release the animal.

  • Stop machinery and establish a safe exclusion area around the find.
  • Allow the spotter catcher or ecologist to identify the animal and decide whether it can move unaided or needs capture.
  • Use clean, secure, ventilated containers and keep handling time as short as possible.
  • Release healthy animals only at an approved nearby location with suitable shelter, unless the permit or ecologist specifies another action.
  • Do not relocate animals outside the project area or to unfamiliar habitat without approval and ecological direction.

During habitat disturbance: 3. Breeding places and other significant finds

If an active breeding place, eggs, young, colony, roost or other significant concentration is found, stop work in the immediate area. The available species profile does not describe a colony or roosting habit for this skink, so any such find requires specialist assessment.

Resume work only after the ecologist and relevant authority have confirmed the response and any required species management program or permit condition.

  • Protect the find from machinery, people, vibration, dust, fire and changes to drainage.
  • Record the location, condition, photographs and immediate risk without repeatedly disturbing the site.
  • Maintain the exclusion area until the breeding event or other risk has been assessed and approval is documented.
  • Do not remove eggs, young or shelter material unless specifically authorised.

During habitat disturbance: 4. Injury, death and incident records

Treat injured animals as a wildlife incident. Minimise handling and transport stress, and seek advice from a veterinarian, wildlife carer or the relevant Queensland authority.

Record every capture, relocation, injury, death, escape and stop-work event.

  • Place an injured animal in a secure, quiet, temperature stable container and contact the nominated wildlife professional promptly.
  • Do not give food, water or medication unless directed by a qualified wildlife professional.
  • Notify the project manager and regulator where required by the permit or approval.
  • Record cause or suspected cause, location, time, photographs, personnel, action taken and final outcome.

After habitat disturbance: 1. Post-clearance checks

Complete a formal close-out rather than treating the end of machinery work as the end of the fauna risk. Confirm that no animals remain in the footprint and that all permit conditions and incident actions are complete.

Have the fauna spotter catcher inspect the cleared area, debris piles, excavations, trenches and retained habitat edges before the site is handed back to construction crews.

Repeat checks after machinery has moved material or altered ground cover.

  • Search remaining cover and cavities that could conceal a skink.
  • Check trenches, pits, pipes and stored materials for trapped fauna.
  • Remove or cover fauna traps created by the works.
  • Document the final inspection, findings and any corrective action.

After habitat disturbance: 2. Relocated animals

Check approved release areas after relocation where the project approval requires it. Do not repeatedly disturb animals to obtain observations.

Use monitoring methods that are proportionate to the number of animals handled, the condition of the retained habitat and the risk created by the works.

  • Record the release location, habitat condition, date, time and animal condition.
  • Inspect release areas for barriers, flooding, fire, machinery access, predators and other hazards.
  • Report any dead, injured or displaced animal found during follow-up.
  • Do not move a released animal again unless directed by the ecologist or relevant authority.

After habitat disturbance: 3. Reporting and compliance

Prepare a fauna completion report for the project manager and approval authority where required. Near threatened species records should be retained even where no animal was captured.

Reconcile the field records against the approved clearing footprint and all permit conditions.

  • Include survey effort, weather, maps, photographs, detections, handling, releases, injuries, deaths and stop-work events.
  • List outstanding actions, responsible people and completion dates.
  • Submit required records to Queensland authorities and update biodiversity databases where appropriate.
  • Keep copies of permits, inductions, daily fauna logs and the final report in the project environmental file.

After habitat disturbance: 4. Incident review

Review any capture, injury, mortality, breeding-place find or unplanned habitat disturbance before the next work stage. Use the review to improve the sequence, exclusion controls and crew briefing.

Escalate repeated incidents to the project ecologist and relevant regulator.

  • Identify the immediate and underlying cause of each incident.
  • Amend the clearing method, exclusion controls or supervision where needed.
  • Rebrief operators and subcontractors before work resumes.
  • Record the review and verify that corrective actions were completed.

Rehabilitation actions: 1. Habitat restoration

Rehabilitation should restore the ground structure and shelter features used by small terrestrial reptiles. The species profile does not identify specific artificial breeding or roost structures for the Chillagoe litter-skink, so restoration should focus on retaining and rebuilding natural habitat rather than installing unsuitable boxes.

Restore the original ground profile, drainage and surface cover as soon as practicable. Retain natural rocks, logs, bark and leaf litter where they are safe and free of weeds or contaminants.

Use locally appropriate native vegetation and materials that match the surrounding woodland and rocky habitat.

  • Replace salvaged ground cover in a stable, natural arrangement under ecological direction.
  • Avoid compacting soil in retained and rehabilitated areas.
  • Reconnect isolated habitat patches where the project layout allows.
  • Keep rehabilitation areas free from vehicle access, stockpiles and repeated mowing.

Rehabilitation actions: 2. Breeding and shelter structures

No species specific requirement for nest boxes, bat boxes, artificial nest sites or roost structures is identified for this skink. Do not install these structures as a substitute for retaining natural ground shelter.

If a qualified herpetologist recommends artificial shelter or breeding features for a particular project, obtain approval, use local materials and include the design and maintenance requirements in the rehabilitation plan.

  • Prioritise natural rocks, logs, bark, leaf litter and suitable native ground cover.
  • Do not place artificial structures where they create heat, flooding, predator access or entrapment risk.
  • Inspect any approved artificial feature for use, damage and weed invasion.
  • Remove or modify structures that are unused, unsafe or causing harm, subject to approval conditions.

Rehabilitation actions: 3. Weeds, fire and water

Control weeds that alter ground cover, shelter or movement through rehabilitated habitat. Manage fire in accordance with the park or land management plan and ecological advice.

Avoid creating artificial wet areas or changing drainage unless this is part of an approved habitat design.

  • Use weed hygiene controls for machinery, soil and rehabilitation materials.
  • Remove invasive plants before they dominate leaf litter, rocks or native ground cover.
  • Prevent sediment, chemicals and construction waste entering retained habitat.
  • Keep rehabilitation watering targeted and temporary, and do not leave animals trapped in open tanks, pits or pipes.

Rehabilitation actions: 4. Long term monitoring

Monitor rehabilitation for establishment, weed invasion, erosion, compaction and loss of ground shelter. Because the species is poorly known, monitoring should record habitat response as well as direct detections.

Set the duration and frequency of monitoring through the project approval and ecological risk assessment.

  • Use repeat searches under comparable conditions where direct species monitoring is warranted.
  • Record search effort, weather, habitat condition, ground cover and all Chillagoe litter-skink detections.
  • Compare rehabilitated areas with retained reference habitat where practicable.
  • Trigger corrective action if rehabilitation fails, weeds spread, shelter is lost or construction impacts continue.
