Pinnacles Leaf-tailed Gecko (Phyllurus pinnaclensis)

The Pinnacles Leaf-tailed Gecko is a rare, rock-dwelling gecko found only in The Pinnacles range near Townsville, Queensland. Its small known population, camouflage and restricted habitat make it a high-priority species during clearing and construction works. It is listed as Critically Endangered at Commonwealth and Queensland levels, so surveys, impact assessment and protective controls should be planned before disturbance.

Conservation status

Commonwealth, EPBC Act 1999: Critically endangered.

Queensland, Nature Conservation Act 1992: Critically endangered.

Breeding season

The Pinnacles Leaf-tailed Gecko is known only from the Pinnacles near Townsville, Queensland. Breeding months have not been documented, so seasonal timing cannot be used to reduce clearing risk.

Breeding mode: Not recorded.

Clutch size: Not recorded.

Incubation period: Not recorded.

Breeding sites: Not recorded. The species shelters among rocks in rainforest, including sufficiently layered granite habitat.

Breeding frequency: Not recorded.

Age at maturity: Not recorded.

Activity and breeding timing may vary with weather, fire conditions, prey availability and site conditions, but this species is known only from the Pinnacles near Townsville and broader regional variation cannot be assessed.

  • Documented breeding timing: No month-specific breeding timing has been documented for the Pinnacles Leaf-tailed Gecko.
  • Night-time emergence and foraging: Adults emerge on boulders at night to hunt insects and spiders, with no seasonal peak recorded.
  • Daytime shelter among rocks: The species hides among rocks during the day, particularly in rainforest associated with layered granite.
  • Survey and detection opportunity: Plan nocturnal searches in suitable rocky rainforest throughout the year because seasonal detection guidance has not been established.
  • Highest clearing risk: Treat clearing and construction as a year-round risk, and retain suitable rainforest and layered granite habitat until a project ecologist confirms an appropriate management approach.

Identification: Appearance

The Pinnacles Leaf-tailed Gecko is a large, prickly gecko with long, slender legs and fingers tipped with sharp claws. It is highly camouflaged and can be very difficult to see against rocks.

Look for a gecko with a strongly textured, spiny appearance. Its camouflage can make the animal almost invisible on boulders and rock faces.

It does not have the sticky toe pads seen in many other geckos. This feature, together with its long legs, claws and prickly body, can help with identification.

  • Large and robust compared with many familiar geckos
  • Long, skinny legs
  • Fingers ending in sharp claws
  • Leaf-tailed gecko body form with strong camouflage

Identification: Size and similar species

A reliable body length or weight should not be assumed in the field. The species was initially mistaken for another leaf-tailed gecko, and genetic and detailed morphological work was needed to confirm its separate identity.

Use an experienced reptile ecologist for confirmation where a leaf-tailed gecko is found. Record clear photographs and the exact location without moving the animal unless handling is authorised.

Identification confidence: High confidence may require detailed morphological or genetic confirmation

Identification: Calls and field signs

A species-specific call or echolocation behaviour is not established for field use. The animal is mainly detected visually during night searches.

Droppings, nests, whitewash, stains and odour are not reliable field signs described for this species. Do not dismiss suitable habitat because no signs are visible.

  • Search boulders and layered rock surfaces after dark
  • Check shaded rock features and rainforest edges carefully
  • Avoid disturbing loose rocks while searching
  • Photograph the animal in place and record the rock and vegetation setting

Distribution: Known Australian range

The Pinnacles Leaf-tailed Gecko is known only from The Pinnacles, a small, rugged range on the western edge of Townsville in north Queensland. No occurrence is known from another Australian state or from overseas.

The species is restricted entirely to the Pinnacles range near Townsville, Queensland. It has been recorded from only a small number of sites within this range.

Known sites should be treated as occupied unless current, suitably designed surveys demonstrate otherwise. The absence of animals during a single survey does not clear habitat for disturbance.

  • State: Queensland
  • Region: Townsville and the Pinnacles range
  • Overseas range: none known

Distribution: Records and site planning

At one known site, three individuals were found during a detailed survey and the local population was estimated at fewer than 25 individuals. A second site with rainforest habitat was surveyed, but no animals were found there, possibly because its metamorphic rock was not sufficiently layered.

Before works begin, check current government records, previous survey reports and local expert knowledge. Map granite outcrops, layered boulder fields, rainforest patches and connections between them.

  • Use the most recent records available for the project area
  • Treat nearby suitable rock habitat as potential habitat even without a previous record
  • Retain access for follow-up surveys and monitoring
  • Escalate any record to the project ecologist and relevant fauna management authority

Distribution: Survey approach

The species is poorly known and can be missed because of its camouflage and low apparent numbers. Night surveys by an experienced herpetologist are appropriate, with effort focused on exposed and layered granite associated with rainforest.

Survey design should be set by a qualified ecologist and should account for weather, access, visibility and the likelihood of repeat visits. A negative result should not be used alone to justify clearing of suitable habitat.

  • Survey at night when animals emerge onto boulders
  • Search multiple suitable rock features and rainforest patches
  • Use repeat surveys where habitat will be cleared or heavily disturbed
  • Record survey conditions, search effort, locations and habitat features

Habitat: Habitat features to look for

The Pinnacles Leaf-tailed Gecko lives among rocks in rainforest and is particularly associated with sufficiently layered granite. Dry rainforest patches and their rocky margins can provide important habitat in a development area.

Prioritise sites containing granite boulders, slabs, crevices and layered rock within or near rainforest. Rugged terrain can make access difficult, but it does not reduce habitat value.

Look for shaded rock surfaces, rock piles and connected rainforest patches. Habitat may be present in small or isolated patches.

  • Layered granite outcrops
  • Boulder fields and rock crevices
  • Rainforest and dry rainforest patches
  • Rocky rainforest edges and sheltered gullies

Habitat: Habitat assessment for works

Map the full rocky and vegetated habitat mosaic, not just areas with dense tree cover. Metamorphic rock may be less suitable where it lacks the layered structure associated with known habitat, but this should be assessed by an experienced ecologist rather than assumed from geology alone.

Keep machinery, access tracks, laydown areas and spoil away from suitable rock and rainforest wherever practicable. Avoid breaking, covering or rearranging boulders.

  • Mark habitat on construction plans before clearing
  • Fence or otherwise clearly identify no-go areas
  • Keep fire management and construction access from fragmenting rainforest patches
  • Inspect proposed work areas for animals before ground disturbance

Habitat: On-site survey conditions

The gecko is most likely to be detected on boulders at night. Daytime searches may still identify suitable habitat, but a lack of sightings during the day should not be treated as evidence that the site is unoccupied.

Record rock type, layering, crevices, rainforest condition and nearby disturbance. These details help refine habitat mapping and future survey effort.

Foraging habitat: Foraging locations

At night, the Pinnacles Leaf-tailed Gecko emerges onto boulders to hunt insects and spiders. Foraging habitat therefore includes the rock surfaces and nearby rainforest that support nocturnal invertebrate prey.

Search exposed boulders, rock ledges and sheltered rock surfaces after dark. These features may be used alongside adjacent rainforest and dry rainforest vegetation.

Keep lighting, noise, dust and machinery away from rocky foraging areas where possible. Sudden changes can affect both the gecko and its prey.

  • Granite boulders and layered rock faces
  • Rock edges beside rainforest
  • Crevices and shaded surfaces
  • Vegetated areas supporting insects and spiders

Foraging habitat: Construction controls

Avoid night lighting directed at boulders or rainforest habitat. Use the lowest practical light spill and shield lights away from retained habitat.

Prevent sediment, concrete washout, chemicals and rubbish from entering rock crevices or rainforest drainage lines. Do not spray insecticide in retained habitat unless specifically approved under the project controls.

  • Use directed, shielded lighting near habitat
  • Maintain clean work areas and prevent chemical spills
  • Keep dust and sediment from settling on rocky habitat
  • Do not remove or relocate boulders for access without ecological approval

Foraging habitat: Diet and observation

The known diet includes insects and spiders. Feeding observations are not needed to identify habitat, but prey-rich rainforest and intact rock features should be retained where possible.

If an animal is found on a work site, stop nearby activity and allow the fauna spotter catcher or ecologist to assess the situation.

Breeding habitat: Potential breeding areas

Breeding sites and breeding timing are not well understood for this species. Treat all suitable layered granite and rainforest habitat as potentially supporting breeding animals, eggs or juveniles.

No specific nest, clutch site, cave, burrow or maternity site has been confirmed for field management. Rock crevices, layered slabs and sheltered spaces within rainforest habitat should therefore be retained and protected.

Do not lift rocks, fill crevices or dismantle boulder piles during clearing unless the action has been assessed and approved by the project ecologist.

  • Layered granite slabs and crevices
  • Sheltered spaces between boulders
  • Rocky rainforest and dry rainforest patches
  • Undisturbed habitat connected to known or potential records

Breeding habitat: Breeding information

Breeding months, clutch size, incubation period and age at maturity are not established for practical site scheduling. Do not rely on a seasonal window to make clearing safe.

Because the species is Critically Endangered and populations are very small, assume that disturbance can affect breeding animals even when no eggs or juveniles are seen.

  • No confirmed breeding season for works planning
  • No confirmed nest or maternity structure
  • No confirmed clutch or litter size
  • No confirmed incubation or development period

Breeding habitat: Controls around potential breeding habitat

Retain potential breeding habitat in place wherever practicable. Set work limits before clearing and brief all machinery operators and fauna personnel on the no-go areas.

If a gecko, juvenile, egg or suspected breeding feature is found, stop work in the immediate area and obtain advice from the project ecologist before proceeding.

  • Use pre-clearance inspections by a suitably experienced ecologist
  • Keep retained habitat free from rock disturbance and material storage
  • Avoid isolating small rainforest and rock patches
  • Record and report all observations

Sheltering habitat: Shelter features

During the day, the Pinnacles Leaf-tailed Gecko hides among rocks and relies on camouflage. Sheltering habitat includes shaded, stable rock features within rainforest and dry rainforest patches.

Look for stable boulders, layered granite, cracks, ledges and shaded spaces that provide cover from heat and predators. The animal may be present even when the surface appears empty.

Do not assume that exposed rock is unused habitat. The species emerges onto boulders at night but may shelter in or beside the same rock system during the day.

  • Layered granite boulders
  • Rock crevices and narrow gaps
  • Shaded ledges and overhangs
  • Rocky rainforest and dry rainforest margins

Sheltering habitat: Protection during clearing

Keep shelter rocks intact and in their natural position. Avoid vibration, blasting, grading, rolling or covering of boulders near retained habitat.

Use physical exclusion controls that do not trap animals. A fauna spotter catcher should inspect any rock or debris that must be moved and follow the approved relocation procedure.

  • Do not place spoil, equipment or waste against habitat rocks
  • Prevent machinery from driving over boulder fields
  • Inspect rock piles and crevices before disturbance
  • Stop work if an animal is exposed or displaced

Sheltering habitat: Daily work planning

Night activity is likely to encounter geckos on boulders, while daytime work can expose animals sheltering among rocks. Plan inspections and exclusion measures around both periods rather than relying on a single pre-clearance check.

Keep retained habitat connected and shaded where possible. Sudden removal of surrounding vegetation can increase heat and exposure around shelter sites.

Threats: Habitat clearing and fragmentation

The species has a very small, restricted population and is vulnerable to changes across its rocky rainforest habitat. Development controls should be conservative and scaled to its Critically Endangered status.

Clearing dry rainforest patches, removing boulders or damaging layered granite can directly remove shelter, foraging and possible breeding habitat. Tracks, compounds and spoil can also fragment small habitat patches.

Avoidance is the preferred control. Keep all practicable work areas outside mapped and potential habitat, and retain connections between rocky rainforest patches.

  • Avoid clearing suitable rock and rainforest habitat
  • Do not use boulder fields for access, storage or spoil
  • Minimise edge effects around retained habitat
  • Restore disturbed areas with locally appropriate native vegetation where approved

Threats: Fire and altered fire conditions

Wildfire is a recognised threat. Construction activities, hot works, machinery and changed fuel conditions can increase fire risk around dry rainforest and rocky habitat.

Apply the project fire management plan strictly. Keep ignition sources controlled, maintain emergency access without damaging habitat and report any fire immediately.

  • Control hot works and machinery exhausts
  • Maintain fire prevention and emergency response measures
  • Avoid unnecessary fuel disturbance in retained habitat
  • Use ecological advice when planning prescribed fire near habitat

Threats: Invasive species and site hygiene

Invasive species can degrade rainforest and rocky habitat and may alter the invertebrate prey base. Construction traffic can spread weeds, pathogens and contaminated soil.

Use clean-down procedures and keep materials, fill and landscaping stock free of weeds and pests. Monitor retained habitat after works and respond to new infestations promptly.

  • Clean machinery before entering or leaving habitat
  • Use approved clean fill and prevent contaminated soil movement
  • Control weeds around retained rainforest and rock features
  • Keep rubbish and food waste away from habitat

Threats: Poaching and handling

Poaching by reptile collectors is a recognised threat. Publicity about exact locations can increase risk, particularly for a species restricted to a small range.

Limit location information to people who need it for compliance, survey or management. Do not collect, photograph with handling or relocate an animal unless authorised under the project and relevant wildlife requirements.

  • Use secure project records for precise locations
  • Brief workers not to approach or collect animals
  • Report suspected collection or unauthorised handling
  • Refer all capture and relocation decisions to the authorised fauna ecologist

Survey methodology: 1. Desktop assessment

The Pinnacles Leaf-tailed Gecko is restricted to The Pinnacles near Townsville and is associated with rainforest and sufficiently layered granite rock. It is mainly detected at night when it emerges on boulders, and its camouflage makes careful, experienced searching essential.

Map rainforest patches, rocky outcrops, layered granite, boulder fields and proposed clearing areas before fieldwork. Check whether the site is within or connected to the known Pinnacles range.

Treat all suitable habitat near the known range as potentially occupied until a qualified ecologist has assessed it. Review previous records, fire history, weed presence, access tracks and proposed night lighting.

Known distribution: Restricted to The Pinnacles near Townsville, Queensland

Known habitat: Rainforest associated with sufficiently layered granite rock

Activity: Emerges on boulders at night and shelters among rocks during the day

  • Confirm the current Commonwealth and Queensland listing before works are planned.
  • Identify whether the proposal may affect a breeding place or other habitat used by the species.
  • Engage a herpetologist familiar with leaf-tailed geckos where identification is uncertain.

Survey methodology: 2. Nocturnal searches

Search suitable rocks, boulders, rainforest edges and crevices at night using careful spotlighting. Move slowly and scan from several angles because the gecko can be almost indistinguishable from the rock surface.

Use experienced observers who can recognise leaf-tailed geckos and other reptiles. Do not rely on a single negative search where suitable habitat is present.

  • Survey during suitable night conditions, avoiding periods when rain, strong wind or other conditions are likely to reduce activity or visibility.
  • Search the full area proposed for clearing and nearby habitat that may be affected by access, vibration, lighting or fire management.
  • Repeat searches when the risk and habitat quality justify them. Set the timing and number of visits through a qualified ecologist because species-specific effort standards are not established.
  • Use a camera or other approved method to document animals and habitat without disturbing them.

Survey methodology: 3. Identification and confirmation

Record photographs and detailed field descriptions for every suspected Pinnacles Leaf-tailed Gecko. The species is large and prickly, with long, slender legs and clawed toes, and lacks adhesive toe pads.

Seek expert confirmation where the animal is difficult to identify. Genetic or detailed morphological assessment may be needed for unusual records or possible confusion with another leaf-tailed gecko.

  • Do not handle an animal solely to obtain an identification photograph.
  • Record the location, date, time, observer, weather, habitat, substrate, behaviour and whether the animal was sheltering or active.
  • Record whether the animal was on layered granite, another rock type, rainforest vegetation or a constructed surface.
  • Submit significant records to the relevant Queensland database or authority through the project ecologist.

Survey methodology: 4. Survey records and constraints

Keep a complete survey log, including areas searched and areas that could not be accessed. A low count does not demonstrate absence because the species is rare and well camouflaged.

Treat a confirmed record, repeated detection, suspected breeding place or occupied shelter as a constraint on the works footprint.

  • Map each detection and the surrounding habitat at a scale useful for construction planning.
  • Record search start and finish times, observers, search conditions and survey limitations.
  • Retain photographs, field sheets, permits, handling records and expert identification advice with the project environmental file.
  • Report any new population or range information promptly to the relevant conservation authority.

Before habitat disturbance: 1. Approvals and permits

Avoid clearing rocky rainforest habitat wherever practicable. Because the species is Critically Endangered and its breeding requirements are poorly known, plan works around confirmed habitat and obtain advice and approvals before entering or disturbing it.

Confirm the Commonwealth and Queensland approval pathway before finalising the design or issuing a clearing instruction. A project that may have a significant impact may require an EPBC referral or approval.

Obtain Queensland approvals and any species management program required for interference with a protected breeding place. Obtain all relevant Queensland permits for survey, handling, collection, relocation or other interactions with protected wildlife.

Commonwealth status: Critically endangered

Queensland status: Critically endangered

  • Have the project ecologist document the listing, proposed impact, avoidance measures and approval conditions.
  • Do not rely on a general fauna spotter catcher licence where a separate authority or permit is required.
  • Keep approval conditions, permit numbers and contact details in the site environmental plan.

Before habitat disturbance: 2. Avoidance and site design

Keep the works footprint out of rainforest, layered granite and boulder habitat wherever practicable. Protect connected dry rainforest patches and rocky refuges from clearing, access tracks, storage, vibration, dust, fire and night lighting.

Use project-specific exclusion areas established by the ecologist and approved by the relevant authority. No species-specific buffer distance is established, so do not apply an unsupported generic distance.

  • Fence and sign exclusion areas before machinery arrives.
  • Keep spoil, fuel, chemicals, materials and vehicles outside exclusion areas.
  • Prevent unauthorised access to rocky habitat and control activities that may increase wildfire risk.
  • Use low-spill, shielded lighting and switch off unnecessary lights near retained habitat.

Before habitat disturbance: 3. Pre-clearance survey and breeding risk

Complete a targeted pre-clearance survey immediately before disturbance, with timing selected by the project ecologist. Search rocks, boulders, crevices and rainforest edges at night, and inspect the proposed clearing footprint and any access route.

Breeding timing, breeding places and seasonal movements are not sufficiently known to set a species-specific work window. Assume that occupied shelter or breeding habitat may be present at any time.

  • Stop the planned clearing if a suspected animal, breeding place or occupied shelter is found.
  • Have the ecologist assess whether further nocturnal searches, specialist identification or authority consultation is needed.
  • Do not remove rocks, dismantle refuges or disturb crevices during the pre-clearance inspection.
  • Update the clearing plan after survey results are reviewed.

Before habitat disturbance: 4. Induction and exclusion controls

Induct every worker, contractor and machine operator before work starts. Explain the species appearance, its nocturnal activity, the exclusion areas and the stop-work process.

Nominate the fauna spotter catcher or ecologist who can direct work and stop activities that may harm wildlife or breach approval conditions.

  • Show workers photographs and the location of exclusion areas.
  • Require workers to report any suspected gecko, injured animal, breeding place or damaged exclusion fence immediately.
  • Prohibit unauthorised handling, collection, photography with flash at close range and removal of rocks or habitat features.
  • Check exclusion fencing and signs daily while works are active.

During habitat disturbance: 1. Sequential clearing

Use a slow, staged approach that gives animals time to move away from disturbance and allows the fauna spotter catcher to inspect each work area. Stop work whenever the species, a possible breeding place or an unexpected habitat feature is found.

Clear vegetation and habitat in small, defined stages rather than opening the whole site at once. Start from the edge of retained habitat and work towards already disturbed ground where this is safe and consistent with the approved method.

Before each stage, inspect rocks, boulders, crevices, rainforest debris and other potential refuges. Do not use machinery to break, roll or bury rocks until the fauna spotter catcher has cleared the area.

  • Keep the fauna spotter catcher within a position where the active work face and retreat route can be seen.
  • Pause between stages to allow observations and safe movement.
  • Retain all habitat identified for protection in the approved plan.
  • Stop immediately if visibility, access or safety conditions prevent effective fauna supervision.

During habitat disturbance: 2. Detection, handling and relocation

Only an authorised and appropriately trained person may capture or handle a gecko. Use the least intrusive method available and avoid chasing an animal into a crevice or across unsafe ground.

Relocation must not occur as an improvised response. It requires approval, a suitable nearby release site and a method set by the relevant authority or specialist.

  • Keep people and machinery away from the animal while the authorised handler assesses it.
  • Do not transport, retain, mark or release the animal unless the permit and approved procedure allow it.
  • Record the original location, condition, identification, handling time, destination and handler for every animal moved.
  • Do not relocate an animal into a different habitat type or outside the approved area.

During habitat disturbance: 3. Breeding places, colonies and occupied shelters

If an active breeding place, eggs, young, a colony or an occupied shelter is found, stop work in the immediate area and protect the feature from people, machinery, vibration, lighting and weather exposure.

The breeding biology of this species is poorly known. Do not assume that a rock crevice or shelter is unused because no animal is visible during a daytime inspection.

  • Establish a temporary exclusion area under the direction of the ecologist.
  • Notify the project manager and relevant authority in accordance with approval conditions.
  • Do not remove rocks, alter the shelter or move eggs or young without specific authorisation.
  • Obtain written advice before work resumes or the feature is modified.

During habitat disturbance: 4. Injured animals and incidents

Treat an injured or distressed gecko as a wildlife incident. Keep the area quiet, shaded and secure while an authorised handler contacts the nominated wildlife carer, veterinarian or conservation authority.

Do not offer food, water or medication unless directed by a qualified wildlife professional.

  • Stop nearby work and prevent handling by untrained workers.
  • Use a clean, secure container only when directed by an authorised person and when safe to do so.
  • Record the injury, suspected cause, location, photographs, handler, destination and outcome.
  • Report any death, unauthorised handling, habitat damage or permit breach under the project incident procedure.

After habitat disturbance: 1. Post-clearance inspection

Complete a formal check before the site is signed off. Post-clearance work should confirm that no animal, occupied shelter or damaged exclusion area has been overlooked and that all approval conditions have been met.

Have the fauna spotter catcher and ecologist inspect the cleared area, retained habitat edges, rock piles, trenches, drains and construction access routes. Search crevices and remaining boulder habitat for trapped, sheltering or injured animals.

Complete additional night searches where suitable habitat remains or where the pre-clearance survey identified a high risk.

  • Check that no rocks or boulders have been displaced into retained habitat or drainage lines.
  • Inspect and repair exclusion fencing after machinery and heavy vehicle movements.
  • Keep temporary pits, trenches and stockpiles managed so animals cannot become trapped.
  • Document the date, observers, area checked, findings and limitations.

After habitat disturbance: 2. Records and reporting

Prepare a completion record that links fauna observations, handling events, incidents and mitigation actions to the approved work stage. Provide required reports to the Commonwealth, Queensland authorities and the land manager within the specified timeframes.

Record both detections and credible negative searches, including the effort and conditions used.

  • Update the site map with final clearing limits, retained habitat and all animal locations.
  • Report new records, injured or dead animals, breeding places and unauthorised impacts through the project approval pathway.
  • Retain photographs, permits, fauna registers, transfer records and correspondence.
  • Brief the project manager and construction supervisor on any outstanding controls before demobilisation.

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

Where relocation has been authorised, confirm the release location and check the animal according to the approved method. Do not assume successful relocation from release alone.

Use a qualified ecologist to decide whether follow-up observations or monitoring are required, particularly where habitat was disturbed or a population was detected.

  • Record the animal's condition at release and any identifying mark or photograph permitted by the approval.
  • Check that the release site retains suitable rainforest, layered rock and shelter.
  • Do not revisit or spotlight release sites unnecessarily.
  • Report any post-release mortality, dispersal concern or repeat detection to the approving authority and project ecologist.

After habitat disturbance: 4. Incident review

Review every fauna incident before the next work stage. Use the findings to improve sequencing, supervision, training, lighting, exclusion controls and habitat protection.

Escalate repeated detections or unexpected habitat use to the project ecologist and authority before continuing with similar works.

  • Identify the immediate and underlying cause of each incident.
  • Confirm whether the work method or approval conditions need to change.
  • Update the induction and site environmental plan.
  • Close out corrective actions with named responsibilities and dates.

Rehabilitation actions: 1. Rocky rainforest restoration

Rehabilitation should rebuild connected rocky rainforest habitat rather than only replant cleared ground. The species depends on specialised rocky shelter, and there is no established basis for installing nest boxes or other artificial breeding structures for it.

Retain and restore native dry rainforest around layered granite and boulder habitat. Reconnect retained patches where the project has created breaks or edges.

Use local provenance plants and methods suited to the site and approved rehabilitation plan. Protect natural rock refuges during earthworks and revegetation.

  • Stabilise disturbed ground without burying or sealing rock crevices.
  • Replace displaced rocks only under specialist direction and without trapping animals.
  • Remove construction debris, excess spoil and temporary access surfaces from retained habitat.
  • Control erosion, sediment, dust and runoff before they reach rocky rainforest.

Rehabilitation actions: 2. Artificial structures and habitat features

Do not install nest boxes, bat boxes, artificial nest sites or other roost structures as a substitute for natural habitat. The species is associated with rocks and boulders, and suitable artificial breeding or roosting structures have not been established.

If an authority or specialist proposes a replacement structure, obtain written approval and a design based on site-specific evidence.

  • Do not place boxes or artificial shelters without an approved purpose, design, location and maintenance plan.
  • Prioritise protection and restoration of natural rock, crevices and rainforest cover.
  • Inspect any approved structure for safety, occupation and maintenance requirements.
  • Remove failed or unsuitable structures if directed by the ecologist or authority.

Rehabilitation actions: 3. Weeds, fire and water management

Manage weeds so native rainforest cover can recover and rocky refuges remain accessible. Plan fire management with the species' small, restricted range and wildfire risk in mind.

Maintain natural drainage and prevent sediment, pollutants and altered runoff from entering retained habitat.

  • Use weed control methods that do not expose animals to toxic products or excessive disturbance.
  • Keep machinery, fuel and chemicals out of rehabilitation and exclusion areas.
  • Coordinate fuel reduction and wildfire planning with the relevant land manager and conservation authority.
  • Do not create artificial water points unless they are part of an approved ecological design.

Rehabilitation actions: 4. Lighting and construction legacy

Reduce night lighting around retained and rehabilitated habitat. The gecko is active at night, so unnecessary light can interfere with movement, detection and use of boulders.

Remove redundant lights, fencing, hardstand and access tracks when construction is complete.

  • Use shielded, downward-directed lights with the lowest practical intensity.
  • Avoid lighting boulder fields, rainforest edges and retained habitat.
  • Reinstate natural ground cover and remove barriers between rocky habitat patches.
  • Inspect rehabilitation areas after storms, fires and major maintenance works.

Rehabilitation actions: 5. Long-term monitoring

Set monitoring through the approval conditions and a qualified ecologist. Monitoring should test whether rocky rainforest habitat is recovering and whether the species continues to use retained or restored areas.

Because the population is very small and the species is difficult to detect, interpret non-detections cautiously.

  • Use repeat nocturnal searches under comparable suitable conditions.
  • Record detections, search effort, habitat condition, weeds, fire impacts, lighting and any new threats.
  • Review monitoring results with the land manager and conservation authority.
  • Adapt weed, fire, lighting and rehabilitation measures when monitoring identifies a problem.
