Leopard Ctenotus (Ctenotus pantherinus)

The Leopard Ctenotus is a small to medium terrestrial skink of arid and semi-arid Australia. It uses spinifex, sandy or stony ground, grassland and associated ground cover, so clearing, soil disturbance, grazing, fire and removal of shelter can affect habitat on development sites.

Conservation status

New South Wales, Biodiversity Conservation Act 2016: Endangered.

Breeding season

Leopard Ctenotus breeds mainly from late spring to early summer and remains active in all seasons. Plan clearing checks around spinifex, litter, rocks and other surface cover, with added care from spring through summer when gravid females, eggs and young may be present.

Reproductive mode: Oviparous, egg laying.

Clutch size: Usually 4 to 7 eggs. Reported values range from 3 to 11 eggs, with means of about 5.1 to 6.1 eggs.

Incubation: Not recorded.

Size at hatching: Hatchlings are about 33 mm long.

Age at maturity: About 10 to 11 months on average.

Nest or egg sites: Not recorded. The species is associated with spinifex and other intact ground cover on sandy, gravelly or stony soils.

Breeding frequency: At least once per year. Two clutches per year are also reported.

Confirm timing locally before clearing, particularly after rainfall or temperature changes that may alter activity, breeding timing and shelter use.

  • Mating: Species-specific mating dates are not recorded. Breeding and egg production are reported from late spring to early summer, so mating may occur mainly from October to December.
  • Gravid females: Gravid females have been recorded, but the survey dates were not preserved clearly enough to assign months. Use the documented late spring to early summer breeding period as the main planning window.
  • Egg laying: Egg production is usually reported in late spring to early summer, corresponding broadly to October to December. Specific laying sites have not been recorded.
  • Incubation: Incubation length and egg persistence in nests or soil are not recorded for this species. Treat eggs laid from October to December as potentially present during subsequent clearing until a local fauna assessment confirms otherwise.
  • Hatchlings: Hatching dates and juvenile emergence are not recorded. As a general planning measure, expect hatchlings after the late spring to early summer laying period, with young potentially present from November into summer.
  • Active period: The species is reported to be active in all seasons. Activity may occur by day or night, including opportunistic nocturnal activity, so night-time clearing should not be assumed to avoid encounters.
  • Highest clearing risk: Risk is highest during the late spring to early summer breeding period, when gravid females, eggs and emerging young may occur among intact spinifex and surface cover. Clearing can also harm active or sheltering animals at any time of year.

Identification

The Leopard Ctenotus is a four-legged skink with an olive-brown to grey-brown body and a strongly patterned back and sides. Field identification should use the whole pattern, body proportions, scale features and locality because several Ctenotus species occur in the same arid and semi-arid regions.

The NSW form is described as grey to olive-brown, with white or yellow spots bordered by a black bar on each side. The Queensland form of Ctenotus pantherinus acripes is described as olive brown, darkest on the head, with about 10 longitudinal series of black-edged white spots. The mid-lateral series can form a black-edged white stripe on the tail.

The underside is white, with pale grey flecking in the Queensland description. The legs are dark brown in that form, and the nails are blackish brown.

Limbs: Four legs.

Maximum recorded snout to vent length: 126 mm.

Hatchling snout to vent length: About 32 mm.

Identification: Size and field comparison

The 180 to 220 mm figure in the NSW determination is a total length, whereas the 126 mm maximum in the trait dataset is snout to vent length. Do not compare these measurements without checking whether tail length is included.

Reliable separation from other Ctenotus requires an experienced reptile ecologist or suitable reference material. Storr's Queensland account distinguishes the species using features including scale counts, keeled subdigital lamellae, spiny plantars and the pattern of black-edged white spots.

  • Record a clear dorsal and lateral photograph, the snout to vent length, total length where possible, sex if known, GPS location and habitat description.
  • Retain scale and pattern details in photographs before handling or release.
  • Confirm difficult records against regional Ctenotus keys or a museum specialist, particularly where Ctenotus hebetior, Ctenotus strauchii or other patterned Ctenotus occur.

Identification: Field signs

No species-specific information was provided on tracks, scats, calls, nests, sloughs or eyeshine. As a skink, it is more likely to be detected by direct observation, targeted searching of ground cover and capture during active reptile searches than by indirect signs.

  • Search around and beneath spinifex clumps, leaf litter, fallen timber, rocks and loose surface debris without destroying potential refuge.
  • Check disturbed edges, cleared margins and retained vegetation because individuals may move between isolated ground-cover patches.
  • Treat an unconfirmed sighting as provisional where the photograph does not show the dorsal pattern, lateral markings and body proportions.

Distribution: State and regional records

The species complex occurs across arid and semi-arid parts of mainland Australia. The documents identify forms in New South Wales, Queensland, Western Australia and the Northern Territory, but they do not provide a complete modern state or bioregional distribution map.

Ctenotus pantherinus acripes is recorded from the arid and semi-arid northern interior of Queensland and adjacent parts of the Northern Territory, as well as Barrow Island in Western Australia. The broader species account gives an Australo-Pacific regional classification, mainland status, an elevation range of 370 to 550 m and a very large reported range size.

In New South Wales, Ctenotus pantherinus ocellifer is known from one specimen collected in 1982 in spinifex on red sand west of Goodooga, near the Queensland border. Extensive surveys in similar habitat in Sturt National Park and Mutawintji National Park had not produced further records at the time of the NSW determination.

  • Treat arid and semi-arid spinifex country in western and north-western Queensland, adjacent Northern Territory and relevant parts of Western Australia as potential habitat.
  • Treat suitable spinifex on red sand in far western New South Wales as potential habitat even where recent records are absent.
  • Use current state databases and a project-specific ecological assessment to confirm the local subspecies or taxonomic treatment.

Distribution: Strongholds and population status

The available documents do not identify a quantified national population, confirmed strongholds or connected subpopulations. The species account reports a stable population trend and Least Concern assessment, while the NSW subspecies is listed as Endangered because of its very restricted known occurrence and continuing threats.

Reported population trend: Stable in the available species-level dataset.

Reported density: 2 to 56 individuals per hectare.

NSW records in the determination: One known specimen, collected in 1982.

NSW status: Endangered.

EPBC Act status: Not listed in the supplied project information.

Habitat: Habitat types

Leopard Ctenotus habitat is generally dry country with spinifex or other low ground cover on sandy, gravelly or stony soils. Habitat quality depends on the continuity and structure of ground cover, not just the presence of the dominant plant species.

The species account lists desert and grassland habitat within the deserts and xeric shrublands biome. Storr records Ctenotus pantherinus acripes in spinifex, including Triodia and Plectrachne, on sandy, gravelly or stony soils.

The NSW form appears to rely on spinifex. The NSW record was from Triodia mitchelli on red sand near the NSW and Queensland border.

  • Map spinifex communities, open arid grasslands, sandy rises, gravel plains and stony ground within the project area.
  • Retain connected patches of spinifex and adjacent shrubs or low ground cover where clearing is unavoidable.
  • Assess the condition of ground cover, including grazing damage, trampling, weed invasion, fire history and bare-ground gaps.

Habitat: Climate and elevation

The available species account gives an elevation range of 370 to 550 m above sea level. Storr describes the relevant Queensland habitats as arid and semi-arid. The documents do not define a narrower temperature, rainfall or seasonal climate limit.

Reported elevation: 370 to 550 m above sea level.

Broad climate: Arid and semi-arid.

Foraging habitat: Diet and feeding method

The Leopard Ctenotus is an active forager that searches across dry ground cover for animal prey. Foraging habitat is therefore likely to include both the cover used for shelter and the open spaces between cover patches.

The diet is mainly arthropods, especially termites. The available data also record small amounts of plant material and vertebrate prey. The species has been described as an active forager rather than a sit-and-wait predator.

Activity can occur during the day and after dark. This means that a daytime-only search may not represent the full period when individuals are active.

Main prey: Arthropods, mostly termites.

Feeding mode: Active foraging.

Recorded diet components: About 5.6% to 11% plant material and about 8.8% vertebrates in the cited diet records.

  • Protect spinifex bases, litter, fallen timber, rocks and other ground structures that support arthropod prey and provide cover during foraging.
  • Avoid assuming that bare patches are unused because individuals may cross open ground between cover clumps.
  • Schedule searches across suitable daytime and, where safe and approved, after-dark conditions when the project risk assessment requires a fuller detection effort.

Foraging habitat: Foraging area

No species-specific home range or daily foraging distance is provided. The available density estimate is 2 to 56 individuals per hectare, but it should not be used to infer a local population size without comparable survey methods and habitat conditions.

  • Assess the full habitat mosaic within and beside the disturbance footprint, including retained spinifex, drainage lines, access tracks and proposed laydown areas.
  • Keep clearing boundaries tight and avoid isolating small ground-cover patches from larger areas of suitable habitat.

Breeding habitat: Breeding biology

The Leopard Ctenotus lays eggs and is associated with dry spinifex and other ground-cover habitats. The supplied documents provide clutch information but do not provide a reliable breeding season, incubation period or age at maturity.

Reproduction: Oviparous.

Clutch size: 3 to 11 eggs, with reported means of about 5.1 to 6.1 eggs depending on the dataset.

Clutches per year: Two clutches per year.

Incubation: Not provided in the supplied documents.

Age at maturity: Not provided in the supplied documents.

Life span: Longest recorded life is 3.2 years.

Breeding season: Not provided in the supplied documents.

Breeding habitat: Breeding habitat

Specific nest sites and egg-laying substrates are not described. The best-supported habitat association is spinifex and other intact ground cover on sandy, gravelly or stony soils. Retained cover is likely to be important for adults and newly hatched young, but the documents do not identify a particular nest structure.

  • Avoid clearing intact spinifex clumps, litter and loose surface material until a spotter catcher has checked them and the approved fauna management procedure has been applied.
  • Do not infer that a recently burnt or grazed patch is suitable breeding habitat merely because spinifex is regenerating.
  • Record any eggs, hatchlings or gravid females and report them under the project fauna management plan because the breeding months are not established in the supplied sources.

Sheltering habitat: Likely refuges

The documents do not describe species-specific burrows, dens, hollows or refuge dimensions. Shelter is most likely associated with intact ground cover and surface structure in spinifex and dry arid habitats.

The NSW determination identifies spinifex and adjacent shrubs and ground cover as habitat that provides shelter for individuals moving between spinifex clumps. Storr's Queensland account places the species in spinifex on sandy, gravelly or stony soils.

No measurements are provided for refuge size, burrow depth, rock cavities, litter depth or distance moved between refuges.

  • Inspect spinifex bases, dense litter, fallen timber, rocks, soil cracks and loose debris before mechanical clearing.
  • Retain refuge patches beside access tracks, work areas and infrastructure where practicable.
  • Use a spotter catcher to manage individuals found under cover and to check material before it is moved or removed.

Sheltering habitat: Refuge condition

Grazing, trampling and frequent non-patchy fire can reduce the density and structure of spinifex and the adjacent ground cover. Soil disturbance can also promote weed invasion, reducing the quality of movement and shelter habitat.

  • Keep vehicles and machinery out of retained spinifex and rocky refuge areas.
  • Do not stockpile spoil, cleared vegetation or construction materials on retained ground cover.
  • Maintain links between spinifex clumps where the project footprint would otherwise create isolated patches.

Threats: Clearing and construction

The main documented threats are habitat loss and degradation, altered fire regimes, grazing and predation by introduced predators. Project activities can add direct mortality, fragmentation, soil disturbance and loss of ground cover.

Clearing removes spinifex, shrubs and ground cover used for shelter, movement and foraging. Trampling and earthworks can damage soil structure and increase weed invasion. Small retained patches may become less useful if they are isolated from surrounding habitat.

Individuals may be killed during clearing or while sheltering under vegetation, rocks, litter and debris.

  • Complete targeted habitat mapping before finalising the disturbance footprint.
  • Mark no-go areas around retained spinifex and rocky ground cover.
  • Clear progressively, inspect habitat before removal and use an appropriately authorised fauna spotter catcher.
  • Keep access tracks, temporary work areas and laydown areas within already disturbed ground where possible.
  • Rehabilitate disturbed ground with locally appropriate native ground cover and manage weeds.

Threats: Grazing and fire

Livestock and feral herbivores can reduce spinifex density and structure, trample clumps, reduce adjacent shrub and ground cover, disturb soil and facilitate weed invasion. Fire used too frequently or applied without a patchy pattern can reduce available habitat and limit recolonisation of burnt areas.

  • Avoid introducing additional grazing or uncontrolled vehicle traffic into retained habitat.
  • Use the approved fire regime for the local ecological community and avoid broad, frequent burns that remove all nearby cover.
  • Retain unburnt refuges and habitat links when fire is required for safety or ecological management.

Threats: Predators, roads and other impacts

The NSW determination identifies foxes and feral cats as threats. The supplied documents do not quantify road mortality, disease or hydrology change for this species. Roads and tracks can nevertheless cause direct mortality and increase access for predators and people, while altered drainage can change sandy or stony ground conditions and vegetation cover.

  • Limit new tracks and keep construction traffic within defined routes.
  • Use fauna exclusion, speed controls and spotter catcher procedures where the project risk assessment identifies likely reptile movements across roads.
  • Control feral cats and foxes through approved regional or project programs where authorised.
  • Prevent sediment, spoil and altered drainage from burying or eroding retained spinifex and ground-cover habitat.

Survey methodology: 1. Habitat assessment and visual searches

The supplied documents do not provide a species-specific survey guideline or minimum survey effort for Leopard Ctenotus. Survey design should therefore be based on the area of suitable spinifex habitat, the proposed disturbance and the species’ unusual cathemeral activity pattern, with all effort and detection conditions recorded.

Map all spinifex, mallee-spinifex and adjacent open ground before selecting survey locations. In NSW, the only known record was in Triodia mitchelli on red sand west of Goodooga, and the species appears reliant on spinifex.

Search systematically through retained and proposed clearing areas using repeatable transects or area searches. Cover spinifex clumps, sandy or stony ground, access tracks and habitat between clumps.

Use both slow daytime searches and searches after dark because Leopard Ctenotus is described as cathemeral, with animals often observed active after dark.

Documented NSW habitat: Spinifex, including Triodia mitchelli, on red sand.

Activity pattern: Cathemeral, with activity recorded during both daylight and after dark.

  • Record the date, start and finish time, observers, area searched, transect length, weather, ground conditions, vegetation type and the number of suitable spinifex clumps examined.
  • Photograph and map any likely habitat, tracks, animals, captures, refuges and disturbance features.
  • Do not treat a failure to detect the species as evidence that it is absent, particularly where suitable spinifex remains intact.

Survey methodology: 2. Spotlighting and timed night searches

Undertake spotlighting or direct observation after dark in suitable spinifex and adjoining sandy or stony habitat. This is supported by the species’ reported frequent activity after dark.

Pair night searches with daytime searches because the species is not strictly nocturnal. Search the same mapped habitat units where practical so that detection results can be compared.

No number of nights, search hours, transect length or area is prescribed in the supplied documents. Set those values in the project survey plan and justify them against the area of suitable habitat and the level of impact.

Documented active body temperature: Mean 33.6 degrees Celsius for active individuals in the wild.

Elevation reported for the species: 370 to 550 metres above sea level.

  • Use a consistent route and observer speed for each repeat search, and record the time spent searching each habitat unit.
  • Record moon, wind, rain, temperature and visibility because these conditions affect detection, even though species-specific detection thresholds are not provided.
  • Avoid driving through spinifex or repeatedly disturbing clumps while spotlighting.

Survey methodology: 3. Trapping and supplementary detection

Use trapping only where it is authorised, justified in the survey design and supervised by appropriately experienced personnel. The supplied documents do not prescribe trap types, trap numbers, trap nights or weather limits for this species.

Any trapping design should be suited to a small terrestrial skink and the sandy, stony or spinifex habitat being sampled. Obtain the relevant animal ethics, scientific and wildlife permits before deployment.

Close traps immediately if conditions become unsafe for reptiles, and inspect them at the frequency required by the permit and animal welfare approval.

  • Treat trapping as supplementary to systematic searches rather than as proof that untrapped areas are unoccupied.
  • Measure and report trap nights, trap lines, trap spacing, searched area and any equipment-related mortality or injury.
  • Release animals at the point of capture unless the approved survey or fauna management plan requires another authorised action.

Survey methodology: Minimum effort and reporting

There is no documented national or state survey effort for Leopard Ctenotus in the supplied material. The ecologist must specify the proposed nights, hours, transects, area and any trap nights before fieldwork starts.

National listing: Not listed under the EPBC Act in the supplied project information.

NSW listing: Endangered, with the NSW determination applying to Ctenotus pantherinus ocellifer.

  • Survey all suitable spinifex habitat within the disturbance footprint and any connected habitat that may be used for relocation or movement.
  • Include searches during daylight and after dark, and repeat searches where the first survey is affected by poor visibility, rain, strong wind or other limiting conditions.
  • Record positive and negative results separately for each habitat unit, including the effort and conditions associated with each result.
  • Submit confirmed records and precise locations to the relevant state wildlife database, such as the NSW BioNet Atlas where the record is in NSW, and retain photographs or voucher information as required.
  • Report the taxon at the level that can be supported, noting that the NSW threatened listing concerns Ctenotus pantherinus ocellifer.

Before habitat disturbance: Avoid and minimise habitat loss

Plan the project around the species’ strong association with spinifex and the limited NSW evidence of occurrence. The NSW determination identifies habitat loss, grazing, altered fire regimes, foxes and feral cats as threats.

Avoid clearing intact spinifex, especially Triodia on red sand and mallee-spinifex habitat. The species’ specific habitat requirements are not fully known, so treat occupied and apparently suitable spinifex as potential habitat.

Retain continuous patches and links between spinifex clumps wherever practicable. The NSW determination notes that shelter between clumps can be affected when ground cover and adjacent shrubs are degraded.

Keep construction access, stockpiles, laydown areas and vehicle movements out of retained spinifex and sandy or stony refuge areas.

  • Design the footprint to retain the largest practicable connected patches of spinifex.
  • Use existing disturbed areas for compounds and access tracks where practicable.
  • Prevent soil compaction and weed spread because trampling degrades soil structure and facilitates weed invasion.

Before habitat disturbance: Check approvals and plan the works

Confirm the state or territory listing, permit and approval requirements before works start. In NSW, Ctenotus pantherinus ocellifer is listed as endangered.

The supplied information states that Leopard Ctenotus is not listed under the EPBC Act. An EPBC referral may still be needed for another protected matter or if the legal listing changes, so check the current protected matters information before finalising the approval pathway.

Prepare a fauna management plan that identifies survey results, retained habitat, clearing limits, fauna spotter catcher responsibilities, stop-work triggers, relocation arrangements and reporting requirements.

  • Obtain wildlife research, handling, relocation and rehabilitation approvals required by the relevant state or territory authority.
  • Confirm whether the proposal affects other threatened species, ecological communities or protected matters before concluding that no EPBC referral is required.
  • Nominate a suitably authorised fauna spotter catcher and an ecologist responsible for decisions about uncertain identifications and injured animals.
  • Stage clearing so that habitat removal is preceded by inspection and so retained habitat remains connected during construction.

Before habitat disturbance: Prepare the site

Complete the pre-clearance survey using the approved method and inspect all suitable spinifex within the impact area before machinery enters.

Mark retained spinifex, no-go areas, movement corridors, access routes and any locations where animals or potential refuge features have been recorded.

Use exclusion fencing where it can safely direct animals away from the work area and towards retained habitat. Design and inspect fencing so that it does not trap reptiles or block access to retained habitat.

  • Brief all workers on the species’ appearance, habitat, likely activity during daylight and after dark, and the procedure for a sighting.
  • Check the clearing boundary each day before work and repair damaged exclusion fencing or signage immediately.
  • Remove waste, mesh, pipes and other materials that could trap small reptiles before work begins.
  • Do not use broadscale fire as a site preparation measure unless it is separately approved and addressed in the fire management plan.

During habitat disturbance: Daily clearing controls

Clearing must proceed slowly enough for the fauna spotter catcher to inspect habitat and direct machinery. Any Leopard Ctenotus sighting, capture or injury must be recorded and managed under the approved fauna management plan.

The fauna spotter catcher must inspect the active work area, exclusion fencing and retained spinifex before clearing starts each day.

Use staged clearing from the disturbed edge towards retained habitat where safe and practicable. Keep machinery at low speed and maintain a clear line of communication between the spotter catcher and operators.

Stop work whenever the spotter catcher cannot see the clearing face, a reptile is located, exclusion controls fail or an animal may be at risk.

  • Keep the spotter catcher within effective viewing distance of the clearing face and do not allow machinery to work ahead of the inspection.
  • Prevent unauthorised access, vehicle parking, refuelling and material storage in retained habitat.
  • Record the daily footprint cleared, personnel, weather, fauna observations, captures, relocations, injuries and control failures.

During habitat disturbance: Handling and relocation

Only an appropriately authorised person should capture or handle a Leopard Ctenotus. Minimise handling time and avoid chasing an animal through dense spinifex or exposing it unnecessarily.

If the animal is healthy, relocate it only under the approved plan to nearby retained habitat that has suitable spinifex and is outside the construction disturbance area. Record the release location and direction of movement.

Do not move the animal to an unassessed site, across a road or into isolated habitat. Do not retain it overnight unless that action is authorised and necessary for animal welfare.

  • Use the handling and hygiene procedures required by the relevant permit and fauna management plan.
  • Do not allow workers without the required authority to catch, transport or release the animal.
  • Place an injured animal in a secure, ventilated container and contact the nominated wildlife carer, veterinarian or rehabilitation facility immediately.
  • Record identification photographs, capture location, release location, time, condition, handler and permit details.

During habitat disturbance: Habitat features and stop-work triggers

The supplied documents identify spinifex clumps, adjacent ground cover, shrubs, red sand and stony habitat as relevant habitat features. Inspect these features before they are disturbed.

Handle any logs, rocks or other potential ground refuges carefully where they occur within spinifex habitat, and replace retained features in their original position where practicable.

A Leopard Ctenotus sighting, capture, injury or suspected mortality is a stop-work event for the immediate area until the fauna spotter catcher has assessed the animal and authorised the next step.

  • Stop work if clearing enters an unapproved retained habitat area or if machinery damages exclusion fencing.
  • Stop work if a fauna spotter catcher cannot safely inspect the work face or if dust, smoke, darkness or equipment prevents reliable detection.
  • Stop work and notify the project environmental officer if repeated records indicate that the approved impact assessment or relocation area is inadequate.
  • Escalate any mortality, injury, unauthorised handling or release to the environmental officer and the relevant regulator where required.

After habitat disturbance: Post-clearance checks and monitoring

Post-clearing work should confirm that animals were not left in isolated habitat and that retained spinifex remains protected. The project record should support regulatory reporting and future management.

Inspect the cleared footprint, retained habitat edges, exclusion fencing and relocation areas after each clearing stage. Search for trapped, injured or displaced reptiles and repair any access points into hazardous areas.

Monitor retained spinifex and connected habitat for damage, weed invasion, soil compaction and loss of ground cover. These conditions are relevant because the NSW determination links grazing and trampling with reduced spinifex structure and degraded soil.

Use repeat daytime and after-dark searches where required by the fauna management plan, with the same effort and conditions recorded so results can be compared.

  • Keep controls in place until the environmental officer confirms that the area is stable and no further construction risk remains.
  • Maintain records of post-clearance inspections, monitoring dates, search effort, observations, mortalities, injuries and corrective actions.
  • Submit confirmed records and incident information to the relevant state authority or wildlife database when required by approval conditions.

After habitat disturbance: Reporting and residual impacts

Prepare a completion report that compares the approved clearing footprint with the area actually disturbed and documents habitat retained, animals handled, relocation sites, incidents and rehabilitation commitments.

Assess whether residual loss or degradation of suitable spinifex remains. Apply any offset, restoration or threatened species management requirement imposed by the approval authority.

Review the result with the project ecologist before removing fauna controls or closing the fauna management plan.

  • Report any failure to meet approval conditions promptly through the project incident process.
  • Retain maps, photographs, survey data, permit records and fauna handling records with the project environmental file.
  • Update the site risk assessment if monitoring detects Leopard Ctenotus or continuing habitat degradation after construction.

Rehabilitation actions: Re-establish spinifex habitat

Rehabilitation should rebuild connected, low-disturbance spinifex habitat rather than simply revegetate the cleared surface. Measures must reflect the species’ association with arid and semi-arid sandy or stony country.

Use locally appropriate native spinifex and other native ground-cover species suited to the site’s soil, climate and reference community. The NSW determination identifies spinifex as the key known habitat feature but does not prescribe a planting mix.

Restore natural soil profiles, minimise compaction and control weeds so that spinifex clumps and the ground cover between them can develop.

Reconnect retained patches where practicable, with rehabilitation areas placed beside existing spinifex rather than isolated within disturbed land.

  • Use local provenance seed or planting material where required by the approval or regional restoration practice.
  • Protect new plantings from grazing, vehicle access and trampling until they are established.
  • Do not claim habitat replacement until spinifex cover, ground structure and connectivity meet the project’s approved success criteria.

Rehabilitation actions: Retain refuge structure and manage threats

Retain or reinstate suitable natural ground refuges, including rocks and logs, where these occur in the local reference habitat and can be placed without creating construction hazards.

Do not install nest boxes for this species because the supplied documents identify it as a terrestrial, egg-laying skink and provide no evidence that nest boxes are useful for it.

Manage foxes and feral cats in accordance with approved control programs because both are identified threats in the NSW determination.

Reproduction: Oviparous, with a reported average clutch of 5.1 eggs and 2 clutches per year.

Documented predators and threats: Foxes and feral cats are identified as threats; grazing and altered fire regimes degrade habitat.

  • Keep rehabilitation areas free of rubbish, mesh, pipes and other artificial traps.
  • Use fencing or other controls to prevent livestock and feral stock from trampling spinifex during establishment.
  • Inspect for weed invasion, erosion, soil compaction, grazing and predator activity at each monitoring visit.

Rehabilitation actions: Fire planning and success measures

Prepare a site-specific fire regime with the land manager and relevant fire authority. Avoid frequent, non-patchy burning that removes spinifex habitat and may prevent recolonisation of burnt areas.

Where fire is proposed, define the purpose, patch size, season, frequency, protection of retained habitat and post-fire monitoring in the approved fire management plan. The supplied documents do not provide a species-specific fire interval.

Set measurable rehabilitation targets before works begin, including native spinifex establishment, retention of connected habitat, acceptable weed cover, absence of damaging grazing and stable soil structure.

  • Monitor rehabilitation during establishment and at the intervals required by the approval, using fixed photographs and mapped sample areas.
  • Include daytime and after-dark fauna searches when monitoring is intended to detect recolonisation or continued use by Leopard Ctenotus.
  • Investigate a failure to establish spinifex or a decline in ground cover, and apply corrective actions such as weed control, access restriction, erosion repair or revised fire management.
  • Submit rehabilitation and fauna monitoring results to the relevant regulator and wildlife database where required.
