Pale-striped Mulch Slider (Lerista speciosa)

Conservation status

South Australia, National Parks and Wildlife Act 1972: Vulnerable.

Breeding season

The species is an egg-laying skink, but its breeding months, incubation period and hatchling emergence are not recorded. Related evidence points to spring breeding, with reproduction possibly continuing towards the end of summer, so plan clearing controls year round and apply added care from September to February.

Reproductive mode: Oviparous

Clutch size: Not recorded

Incubation: Not recorded

Size at hatching: Not recorded

Age at maturity: Not recorded

Nest or egg sites: Not recorded

Breeding frequency: Not recorded

Confirm timing locally with the project ecologist, taking account of local rainfall and temperature triggers because species-specific monthly observations are not available.

• Mating: Timing is not recorded for this species. Breeding adults of the related Nevin’s slider were collected in spring, September to November, so treat this period as a likely mating window.
• Gravid females: The timing of gravid females is not recorded. Use September to February as a precautionary window based on related evidence for spring breeding and reproduction continuing towards the end of summer.
• Egg laying: Egg laying is confirmed by the species being oviparous, but its timing and egg sites are not recorded. Treat September to February as a precautionary period, based on related spring breeding and reproduction continuing towards the end of summer.
• Incubation: The incubation period and the months when eggs remain in soil or other cover are not recorded. Retain and inspect suitable ground cover from September to February as a precaution linked to the inferred breeding window.
• Hatchlings: Hatchling emergence is not recorded. Treat September to February as a precautionary period because related evidence indicates spring breeding and reproduction may extend towards the end of summer.
• Active period: Seasonal activity is not recorded for this species. Members of the genus are generally nocturnal and may feed on the surface at night, with captive animals reported as most active from 1600 to 2000 hours.
• Highest clearing risk: No peak clearing-risk months are documented for this species. Use a year-round precautionary approach, with additional inspection and handling controls from September to February when related evidence indicates likely breeding and young may be present.

Identification

The supplied documents provide the scientific name, common names and taxonomic history, but no diagnostic description, measurements or photographs. Identification in the field should therefore be confirmed by an experienced reptile ecologist, especially where other small Lerista occur.

Lerista speciosa is a slider skink in the family Scincidae. The names Pale-striped Mulch Slider and Musgrave Slider are associated with this species.

Scientific name: Lerista speciosa

Family: Scincidae

Other recorded name: Cybelia speciosa

Identification: Size and field appearance

Body length, weight, colour pattern, scale characters, limb condition and sexual differences are not provided in the supplied documents.

Do not assign a small skink to this species from colour alone. Record clear photographs of the head, dorsum, flanks, underside, tail and feet, together with a scale reference, and retain the location and habitat details.

Body size: Not documented in the supplied documents

Weight: Not documented in the supplied documents

Sexual dimorphism: Not documented in the supplied documents

Identification: Similar species and field signs

The supplied documents do not provide characters that separate Lerista speciosa from other mulch sliders, robust sliders or fine-lined sliders.

Tracks, scats, calls, nests, sloughs and eyeshine are not documented as reliable species-level field signs. Treat an unobserved animal, shed skin or burrow record as Lerista habitat evidence rather than a confirmed species record.

• Use a qualified reptile taxonomist or current regional key for confirmation.
• Record the exact search method and microhabitat where the animal or sign was found.

Distribution: National range

The supplied distribution record gives a state-level range only. It records Lerista speciosa from South Australia and does not identify bioregions, strongholds, subpopulations or population estimates.

Lerista speciosa is recorded from Australia, with South Australia listed as its distribution state. No other state or territory is listed for this species in the supplied taxonomic account.

States and territories recorded: South Australia

Bioregions: Not documented in the supplied documents

Known strongholds: Not documented in the supplied documents

Distribution: Population information

The supplied assessment table records the population trend for Lerista speciosa as unknown. It does not provide an abundance estimate, occupied area, population size or identified subpopulations.

Population size: Not documented

Population trend: Unknown

Subpopulations: Not documented

• Do not infer local absence from a failed search without considering search timing, weather, ground cover and survey method.
• Map all confirmed records and retain habitat observations so local occupancy can be assessed across the project area.

Habitat: Recorded habitat

The only habitat category supplied for Lerista speciosa is open woodland. The documents do not specify vegetation associations, soil types, elevation, rainfall limits or required ground structures.

The assessment table assigns Lerista speciosa to open woodland. This is the best available habitat information for project screening.

Recorded broad habitat: Open woodland

Vegetation community: Not specified

Elevation range: Not documented

Climate limits: Not documented

Habitat: Site assessment

Within open woodland, inspect leaf litter, mulch, fallen timber, loose bark, soil cracks and other ground-level cover as potential skink habitat. These features are general survey considerations for small terrestrial skinks, not confirmed species requirements for Lerista speciosa.

• Map intact woodland, disturbed woodland and cleared areas separately.
• Record canopy cover, dominant plants, litter depth, fallen timber, soil condition and nearby drainage features.
• Avoid treating the broad open woodland label as a substitute for a site-specific habitat assessment.

Foraging habitat: Feeding information

No species-specific diet, prey, feeding method or foraging range is provided. General small-skink survey practice should be used without presenting unverified prey or movement distances as characteristics of this species.

The supplied documents do not identify the diet, food plants, prey types, feeding period or foraging distance of Lerista speciosa.

Diet: Not documented

Feeding period: Not documented

Foraging range: Not documented

Foraging habitat: Survey implications

Search likely ground-foraging areas within open woodland, including leaf litter, mulch, fallen timber margins and loose surface material. Inspect these areas carefully before disturbance because small sliders may be difficult to detect during active clearing.

• Use hand searches and targeted lifting of suitable ground cover only where permitted and where material can be replaced safely.
• Keep a record of the cover type, soil condition and weather associated with every detection.
• Do not collect prey or food plants as evidence of species presence.

Breeding habitat: Breeding biology

The supplied documents contain no breeding records for Lerista speciosa. The breeding information below identifies the information gap and sets out conservative inspection practice rather than asserting undocumented biology.

Seasonal breeding, clutch size, incubation period, age at maturity, lifespan and the presence of dependent young are not documented in the supplied documents.

Breeding season: Not documented

Clutch or litter size: Not documented

Gestation or incubation: Not documented

Age at maturity: Not documented

Lifespan: Not documented

Breeding habitat: Breeding habitat and controls

No nest, egg-laying site, nursery habitat or breeding shelter is identified. Treat suitable ground cover in open woodland as potentially important until an appropriately timed survey has tested for occupancy.

• Schedule pre-clearance searches at times recommended by the project herpetologist and permit conditions.
• Stop work and protect the immediate area if an animal, egg or occupied refuge is found.
• Use a spotter catcher experienced with small terrestrial skinks for staged clearing and habitat relocation decisions.

Sheltering habitat: Potential refuges

No refuge type or refuge dimensions are specified for Lerista speciosa. Small terrestrial skink survey methods should focus on ground-level cover within the recorded open woodland habitat.

The supplied documents do not document burrows, nests, tree hollows, rock shelters, fallen timber dimensions or other confirmed refuges for this species.

Confirmed refuge type: Not documented

Refuge size: Not documented

Hibernation or torpor site: Not documented

• Inspect leaf litter, mulch, loose bark, fallen timber, soil cracks and shallow surface cover before clearing.
• Treat any small burrow or concealed ground refuge in suitable woodland as potential fauna habitat until checked.

Sheltering habitat: Clearing practice

Retain and inspect ground cover where practicable. Move cover carefully, keep it close to its original position unless relocation is authorised, and replace it after inspection where no animal is found.

• Clear in stages towards retained habitat so fauna have an opportunity to move away.
• Use hand tools around suspected refuges and avoid crushing loose cover with machinery before inspection.
• Record the location and condition of any refuge associated with a detection.

Threats: Direct project risks

The supplied documents do not provide a species-specific threat assessment. For a South Australian skink associated with open woodland, the main project risks are direct habitat removal, ground disturbance and loss of habitat continuity.

Clearing open woodland can remove the broad habitat type recorded for Lerista speciosa. Earthworks, stockpiling, trenching and vehicle movements can also destroy concealed ground refuges or kill animals during clearing.

• Clearly mark no-go habitat and retain connected woodland where project design allows.
• Complete pre-clearance searches immediately before vegetation and ground disturbance.
• Use staged clearing and fauna spotter catcher supervision in suitable habitat.
• Prevent machinery, spoil and materials from entering retained woodland.

Threats: Fragmentation and roads

The supplied documents do not quantify the effects of fragmentation or roads on this species. New access tracks and linear infrastructure can nevertheless reduce the continuity of open woodland and increase direct vehicle interaction with ground-dwelling fauna.

• Minimise the width and number of temporary and permanent access tracks.
• Set low vehicle speeds through retained habitat and use fauna awareness controls for project traffic.
• Restore temporary work areas with suitable local ground cover after construction.

Threats: Fire, predators, disease and hydrology

Species-specific effects of fire, introduced predators, disease and hydrology change are not documented. Assess these pressures through the project impact assessment rather than assuming that a general threat ranking applies to Lerista speciosa.

• Retain unburnt refuge areas where practicable during planned fire or fuel reduction works.
• Control domestic animals and manage waste that may attract introduced predators to work areas.
• Prevent sediment, chemicals and altered drainage from entering retained woodland.
• Report unusual mortality or diseased reptiles to the project environmental officer and relevant wildlife authority.

Survey methodology: 1. Active searches

The supplied records identify Pale-striped Mulch Slider as a South Australian species associated with open woodland. They do not provide a species-specific survey protocol, body size, breeding period or detection rate. Use the following general survey approach for a small, ground-dwelling Lerista, and set final effort through the project risk assessment and current South Australian survey requirements.

Search retained and proposed clearing areas for sliders, tracks and shelter sites, with particular attention to leaf litter, loose mulch, fallen timber, loose bark, rocks and the bases of tussocks or shrubs.

Search during periods when reptiles are likely to be active, avoiding very cold, very hot, flooded or persistently wet conditions that reduce detection.

Use repeated systematic searches by experienced herpetologists, recording the search area, start and finish times, weather, ground conditions, observers and all habitat features examined.

• Inspect ground cover carefully before it is moved, because a mulch slider may remain concealed beneath loose surface material.
• Do not rely on spotlighting alone for this species, because the available records indicate a ground-dwelling slider rather than a conspicuous nocturnal species.

Survey methodology: 2. Pitfall and drift-fence trapping

Where permitted and suitable, use pitfall traps linked by low drift fences to sample ground-dwelling reptiles across representative open woodland habitat.

Place trap lines across habitat variation and near intact ground cover, rather than only along cleared edges or vehicle tracks.

Operate traps for the number of trap nights approved in the project survey design, with daily checks and additional checks during hot, wet or otherwise stressful conditions.

• Provide shade, shelter and moisture protection in each trap, and close traps immediately if weather or animal welfare conditions become unsuitable.
• Use escape devices or fauna-friendly trap designs for non-target animals, and stop trapping if repeated mortality, overheating, flooding or severe stress occurs.
• Record trap locations, trap nights, weather, non-target captures, repairs and any Lerista captures.

Survey methodology: 3. Cover and habitat searches

Use targeted searches of natural cover and, where appropriate, temporary artificial cover placed in the open woodland habitat identified for this species.

Inspect cover consistently across the survey area and replace it after inspection so that the site is not unnecessarily disturbed.

Combine cover searches with searches of loose mulch, litter, logs, rocks and shallow shelter sites, because these features are relevant to a mulch slider's ground-level habitat.

• Do not lift heavy logs or rocks without first checking for animals underneath and ensuring that the feature can be replaced safely.
• Keep a separate register of natural shelter features and artificial cover locations so that they can be checked again before clearing.

Survey methodology: Minimum effort and reporting

• Obtain approval for the survey design from the project ecologist and confirm that the methods, timing and trapping effort meet current South Australian requirements before fieldwork starts.
• Report the total area searched, transect or search effort, number of observers, trap nights, artificial cover checks, weather, conditions, detection results and survey limitations.
• Submit verified records, including coordinates, date, observer and photographic or voucher evidence where required, to the relevant South Australian wildlife database.
• Provide all positive and negative survey results to the project environmental officer and retain the field data, photographs, trap sheets and animal welfare records.

Before habitat disturbance: Avoid and minimise

Treat all suitable open woodland ground cover as potential habitat until a field assessment shows otherwise. The records place the species in South Australia and list open woodland as its habitat category, while the supplied material does not define a species-specific buffer or seasonal clearing window.

• Retain intact open woodland patches and continuous ground cover wherever practicable.
• Retain fallen timber, loose mulch, leaf litter, rocks, loose bark and other low shelter features within areas excluded from clearing.
• Keep retained habitat connected to other suitable ground cover and avoid creating isolated remnants surrounded by bare ground, roads or stock access.
• Confine access tracks, laydown areas, spoil placement and machinery movement to already disturbed areas where practicable.

Before habitat disturbance: Approvals and planning

• Check the current EPBC Act status and obtain project-specific advice before works proceed, even though the supplied project record states that the species is not nationally listed.
• Confirm the current South Australian listing, permits and approval conditions with the relevant state authority before surveying, trapping, handling or relocating animals.
• Prepare a fauna management plan that identifies the ecologist, authorised fauna spotter catcher, machinery exclusion zones, encounter procedures, relocation areas, injured-animal arrangements and reporting requirements.
• Stage clearing so that the spotter catcher can inspect each work area immediately before disturbance and so that retained habitat remains available while adjacent areas are cleared.

Before habitat disturbance: Site preparation

• Complete a pre-clearance survey using the approved methods and repeat the inspection if clearing is delayed or the site changes materially.
• Mark no-go areas, retained woodland, logs, rocks, mulch piles, litter patches and any confirmed or potential shelter sites before machinery enters.
• Install exclusion fencing where it can keep animals out of the work area without cutting off access to retained habitat or creating a trap.
• Brief all operators on the species identification, stop-work triggers, exclusion zones, speed limits and requirement to follow the spotter catcher's direction.

During habitat disturbance: Daily controls and machinery coordination

The fauna spotter catcher should control the release of each work area and remain in direct communication with machinery operators. Clearing should proceed in small, inspectable stages, with immediate action for any Lerista or suitable shelter feature found.

• Inspect the active work area at the start of each day and after breaks, weather changes or changes in the clearing footprint.
• Keep machinery stopped while the spotter catcher checks ground cover, logs, rocks, mulch, litter and other shelter features in the next work zone.
• Use low-speed, staged clearing and do not allow machinery to work ahead of the cleared and inspected area.
• Maintain visible or radio communication between the spotter catcher, operator and site supervisor throughout clearing.
• Recheck material that is pushed into piles, placed in spoil areas or moved across the site before it is loaded or buried.

During habitat disturbance: Habitat feature handling

• Leave retained logs, rocks, loose bark, mulch and leaf litter undisturbed unless their removal is approved and the spotter catcher has inspected them.
• Where a feature must be removed, lift or roll it under the spotter catcher's direction, inspect the underside and relocate the feature to approved retained habitat if safe to do so.
• Inspect burrows, crevices, dense litter and the edges of mulch piles before filling, grading or compacting them.
• Apply the same inspection and handling process to hollow-bearing trees, stumps, nest boxes or wet areas if they occur in the work footprint, even though these features are not identified as species-specific habitat in the supplied records.

During habitat disturbance: Animal encounters and stop-work triggers

• Stop work immediately when a Pale-striped Mulch Slider is found, when the animal's location is uncertain, or when the spotter catcher identifies a likely occupied shelter feature.
• Allow only an appropriately trained and authorised person to capture or handle the animal under the relevant permit and fauna management plan.
• Keep handling to the minimum needed for safety, identification, photography and relocation, and do not hold the animal longer than necessary.
• Relocate the animal to nearby suitable retained habitat agreed in the fauna management plan, using a shaded container and avoiding release into exposed or heavily trafficked ground.
• Take injured or heat-stressed animals to the nominated veterinarian or wildlife carer and record the transfer.
• Do not resume work until the animal has been secured or released and the spotter catcher has cleared the area.
• Escalate any repeated encounters, mortality, injury, unauthorised handling, damaged exclusion fencing or clearing outside the approved footprint to the site supervisor and environmental officer.

During habitat disturbance: Records

• Record each observation, capture, relocation, injury, death and near miss with date, time, coordinates, habitat feature, condition, action taken and the names of the personnel involved.
• Photograph the animal and its habitat where this can be done without delaying release or causing additional stress.
• Record cleared areas, retained habitat, moved features, daily inspections, stop-work events and any departure from the approved method.

After habitat disturbance: Post-clearance checks

Post-clearing work should confirm that no animals or shelter features were missed and that retained habitat controls remain effective. Monitoring and reporting should be scaled to the level of habitat removed and the conditions of approval.

• Inspect the cleared footprint, pushed material, spoil piles, machinery routes and retained edges after each clearing stage.
• Check for live or injured animals, carcasses, damaged shelter features and animals trapped against fencing or other barriers.
• Remove or repair temporary fencing and other controls only after the fauna spotter catcher and environmental officer confirm that they are no longer needed.

After habitat disturbance: Monitoring and reporting

• Monitor retained open woodland and ground cover for the period required by the fauna management plan or approval conditions.
• Repeat targeted searches or trapping only where the approved monitoring design requires them and where animal welfare and permit conditions can be met.
• Compare detections, mortality, relocated animals, retained habitat and rehabilitation progress with the approved project commitments.
• Submit required records to the relevant South Australian wildlife database and provide an incident and compliance report to the project environmental officer.

After habitat disturbance: Residual impacts

• Review whether the project has retained connected open woodland and sufficient low shelter cover for a ground-dwelling Lerista.
• Where approved impacts remain, implement any required offset, restoration or compensatory habitat measure and document its location, area and management obligations.
• Keep weed, vehicle access, erosion and uncontrolled fire management under review in retained habitat and rehabilitation areas.

Rehabilitation actions: Ground habitat and planting

Rehabilitation should recreate the open woodland setting and the ground-level shelter that a mulch slider can use. The supplied records do not name preferred plant species or define rehabilitation targets, so use locally indigenous South Australian species and measurable project-specific targets approved by the ecologist.

• Re-establish locally indigenous open woodland plants suited to the pre-clearing community and site soil conditions.
• Restore a continuous layer of leaf litter, small woody debris and suitable mulch without importing material that could carry weeds, chemicals or pest animals.
• Reinstate salvaged logs, loose bark, rocks and other safe ground shelters from the site where they can be placed without creating hazards or blocking drainage.
• Avoid leaving large areas of compacted bare soil between retained habitat and rehabilitation areas.

Rehabilitation actions: Threat management

• Control weeds that replace native ground cover or increase bare ground and erosion.
• Limit vehicle access and prevent storage of materials in rehabilitation areas after handover.
• Use a fire management approach that protects regenerating open woodland and retains suitable ground cover, while meeting South Australian fire safety requirements.
• Manage introduced predators and pest animals where they are identified as a project impact and control is approved.

Rehabilitation actions: Success measures and follow-up

• Set project-specific success measures for plant establishment, ground-cover continuity, retention of logs and rocks, weed cover, erosion, unauthorised access and evidence of reptile use.
• Inspect rehabilitation after establishment and following major disturbance such as fire, flood or construction access.
• Use repeat photographs, mapped habitat features and targeted Lerista searches to document whether the restored ground layer is developing toward the retained open woodland condition.
• Repair failed areas, replace lost shelter features and continue weed, access and erosion controls until the agreed rehabilitation criteria are met.
