Orange-speckled Forest-skink (Tumbunascincus luteilateralis)

The Orange-speckled Forest-skink is a medium-sized terrestrial rainforest skink known from Queensland, including mid-eastern Queensland. It is listed as Vulnerable under Queensland legislation, so clearing and construction works should avoid suitable rainforest habitat and use a targeted ecological assessment, pre-clearance checks and fauna spotter catcher controls.

Conservation status

Queensland, Nature Conservation Act 1992: Vulnerable.

Breeding season

Species-specific breeding months have not been recorded for the Orange-speckled Forest-skink. For clearing and construction planning in Queensland, assume animals may be present year-round in suitable rainforest and do not rely on a seasonal clearance window.

Breeding mode: Not recorded.

Clutch or litter size: Not recorded.

Incubation or gestation: Not recorded.

Nest or breeding place: Not recorded.

Dependent young period: Not recorded.

Age at maturity: Not recorded.

Breeding frequency: Not recorded.

Activity and breeding timing may vary between years and regions, so local surveys should guide the timing and methods of clearing or construction works.

  • General activity in rainforest habitat: Use year-round presence as the working assumption because seasonal activity patterns are poorly known for this rainforest skink.
  • Potential breeding and dependent young: Breeding and young may occur in any month, but this is a precautionary planning envelope rather than a documented seasonal pattern.
  • Suitable rainforest habitat occupied: Retain suitable rainforest habitat throughout the year and check sheltering areas before disturbance.
  • Highest clearing risk: Treat all months as high risk because breeding timing, shelter sites and dependent young periods are not recorded, and the species is Vulnerable in Queensland.

Identification: Appearance

The Orange-speckled Forest-skink is a medium-sized rainforest skink with yellow to orange colouration on the underside and pale flecks along the flanks. Identification can be difficult in the field, particularly where photographs are poor or the animal is seen briefly.

Live animals have yellow to orange bellies. Females tend to be more yellow, while males are more orange and may approach the orange colour of the flanks.

The flanks have numerous tiny, dark-edged pale flecks on a darker ground colour. A dark supra-axillary blotch is present. The flank ground colour is generally more orange or yellow than in the similar Karma skinks.

Identification: Diagnostic scale features

The species has six supralabials. The fourth supralabial is below the centre of the eye and contacts the eye.

The lower secondary temporal scale typically overlaps the upper secondary temporal scale. This was present on both sides in 20 of 24 examined specimens, and on one side in the remaining four.

  • Use clear lateral head photographs where possible.
  • Do not rely on belly colour alone, because related rainforest skinks can show similar yellow to orange colouration.

Identification: Similar species

The main identification issue is separation from Karma murrayi and Karma tryoni. These species share several features, including pale flank flecks, a dark supra-axillary blotch and similar ventral colour variation.

The temporal scale arrangement is the most useful reported feature for separating the Orange-speckled Forest-skink from Karma. Confirm difficult records with a suitably experienced herpetologist or taxonomist.

Identification: Calls and field signs

No distinctive call, echolocation, droppings, nest, whitewash, odour or other field sign is established for this species. Detection should therefore focus on direct observation and careful searches of suitable rainforest ground habitat.

Record the exact location, habitat, photographs, sex where apparent, behaviour and any scale characters that can be seen without handling the animal.

Distribution: Australian range

The Orange-speckled Forest-skink is recorded in Queensland and is associated with eastern Australian rainforest environments. The available locality information is limited, so a lack of previous records on a site should not be treated as evidence that the species is absent.

The species is mapped in Queensland. The available information places relevant records in mid-eastern Queensland, including observations near Mt Dalrymple.

No confirmed records are identified here from other Australian states or territories.

State or territory: Queensland

Regional context: Mid-eastern Queensland, including the Mt Dalrymple area

Distribution: Overseas range

The species is Australian and no overseas range is recognised.

Distribution: Planning and survey implications

Treat suitable rainforest habitat as potential habitat, even where the species has not previously been recorded. Review recent records, vegetation mapping and local expert knowledge before finalising clearing boundaries.

For a Queensland Vulnerable species, arrange a targeted assessment by a suitably qualified ecologist where works may affect rainforest or connected forest habitat.

Habitat: Vegetation and landscape

The Orange-speckled Forest-skink is described as a rainforest skink. Detailed habitat associations are poorly known, so site assessments should consider both the vegetation community and the quality of the ground layer.

Prioritise rainforest remnants and other areas with a closed or relatively dense canopy, layered vegetation and a moist forest floor. Give additional attention to rainforest retained along gullies, sheltered slopes and drainage lines.

Consider connected forest as well as the immediate clearing footprint. Small remnants may still provide habitat, particularly where they retain dense ground cover and links to larger forest areas.

Habitat: Ground features to inspect

Search beneath and around leaf litter, fallen timber, rocks, dense ground plants and other shaded cover. These are general search features for rainforest skinks and should be checked where they occur on the site.

Map areas with heavy machinery access, temporary stockpiles or laydown areas that could remove ground cover or compact the forest floor.

Habitat: Site assessment guidance

Use habitat mapping and a walked inspection to identify higher-quality rainforest areas before vegetation is marked. Include retained edges and likely escape habitat in the assessment.

Where habitat is fragmented or disturbed, record the condition of the canopy, ground layer, leaf litter, fallen timber, weeds and moisture regime rather than classifying the area only as rainforest or non-rainforest.

Foraging habitat: Likely foraging areas

The diet and foraging behaviour of the Orange-speckled Forest-skink are not well documented. Manage the ground layer conservatively because clearing, compaction and removal of cover may reduce access to prey and refuges used by small rainforest skinks.

Inspect shaded rainforest ground, leaf litter, fallen timber, rocks and dense low vegetation. Retain these features wherever practicable within and beside the work area.

Give priority to moist, connected ground habitat rather than isolated patches of heavily disturbed ground.

Foraging habitat: Survey approach

Use quiet, slow searches during suitable daylight conditions and inspect cover carefully before it is moved. Search methods should be selected by the project ecologist after considering terrain, weather, vegetation density and the proposed disturbance.

Do not turn or remove cover unnecessarily. Replace natural cover in its original position after inspection where this can be done safely.

Foraging habitat: Works controls

Keep vehicles, workers and materials out of retained rainforest habitat. Minimise soil disturbance, compaction, invasive weeds, sediment movement and changes to local drainage.

If a skink is found, stop activity near the animal, allow the fauna spotter catcher to assess it and follow the approved Queensland fauna handling and release procedure.

Breeding habitat: Potential breeding areas

Specific breeding places, breeding seasons and reproductive parameters have not been established for the Orange-speckled Forest-skink. Until local information is available, manage suitable rainforest ground habitat as potential breeding habitat throughout the year.

Inspect intact, shaded rainforest ground with leaf litter, fallen timber, rocks, dense ground cover and other natural shelter. Avoid disturbing these features during site preparation.

Include habitat beside the clearing footprint in the assessment because breeding or refuge areas may extend beyond the area where vegetation is removed.

Breeding habitat: Breeding place controls

Do not remove, fill, burn or otherwise disturb suspected shelter or breeding features unless the action has been assessed and authorised under the project approvals.

Where clearing cannot be avoided, have a suitably qualified ecologist and fauna spotter catcher inspect the area before disturbance and maintain a clear process for stopping work if an animal or potentially occupied feature is found.

Breeding habitat: Seasonal planning

No reliable breeding months are established. Avoid assuming that works outside a particular season will remove breeding risk.

Use staged clearing, reduced work fronts and progressive inspection where practicable. Keep retained habitat connected and protect it from machinery, spoil, runoff and unnecessary lighting.

Sheltering habitat: Features to retain

Sheltering and daily refuge sites have not been documented in detail for this species. General rainforest-skink survey practice should focus on shaded ground cover and natural structures that provide protection from heat, predators and disturbance.

Retain leaf litter, fallen branches and logs, rocks, dense ground plants, moist crevices and other natural cover wherever they occur.

Avoid unnecessary clearing of the forest floor beneath retained trees. Canopy retention alone may not preserve the shelter conditions used by a small terrestrial skink.

Sheltering habitat: Inspection and handling

Inspect cover systematically before it is disturbed, using a fauna spotter catcher where required by the project approval. Work slowly and avoid trapping animals against machinery, spoil piles or temporary fencing.

If an animal is captured, keep handling brief and release it into suitable nearby habitat in accordance with the approved fauna management plan.

Sheltering habitat: Construction site management

Fence retained habitat clearly and prevent access by vehicles, plant and storage areas. Keep excavations, trenches and pits managed so that animals cannot become trapped.

Check trenches, pits and other artificial hazards regularly during active works, particularly where they adjoin rainforest habitat.

Threats: Rainforest clearing and fragmentation

The Orange-speckled Forest-skink is Vulnerable in Queensland, and its limited known distribution means local habitat loss should be treated seriously. The main project risks are direct clearing, habitat degradation and killing or trapping animals during site works.

Removal of rainforest reduces available habitat and can isolate remaining patches. Clearing boundaries should be minimised, surveyed before works and clearly marked on the ground.

Retain connected forest, sheltered gullies and high-quality ground habitat wherever practicable. Do not use a narrow retained strip as a substitute for avoiding a larger habitat patch where the patch can be protected.

Threats: Ground disturbance

Grading, soil compaction, trenching, stockpiling and removal of leaf litter, logs and rocks can destroy shelter and foraging habitat.

Keep construction compounds, access tracks, spoil and materials out of retained rainforest. Control sediment, weeds, runoff and altered drainage that could degrade adjacent habitat.

Threats: Direct mortality

Animals may be injured or killed by clearing machinery, vehicles, excavation, vegetation removal and uncontrolled debris handling.

Use staged clearing, pre-clearance searches, a trained fauna spotter catcher and a documented stop-work and release procedure. Inspect open trenches and pits regularly and provide safe escape measures where appropriate.

Threats: Fire, weeds and edge effects

Unplanned fire, invasive weeds, increased drying and disturbance along new edges can reduce the quality of retained rainforest habitat.

Maintain protective buffers where required by the project approval, limit unnecessary edge creation, manage weeds and prevent construction activities from spreading fire, soil or sediment into retained habitat.

Survey methodology: 1. Desktop assessment

The orange-speckled forest-skink is a poorly known terrestrial rainforest skink. Surveys should focus on suitable rainforest habitat, ground shelters and leaf litter, and should be repeated under conditions when skinks are active.

Map rainforest and adjoining retained vegetation within and near the work area. Check records, mapped habitat, recent aerial imagery, proposed clearing, access tracks and construction footprints.

Confirm the current Queensland listing and whether the project requires assessment under the Commonwealth EPBC Act. Seek advice from the Queensland environmental regulator where the site may support the species.

  • Review local records and museum or wildlife databases before fieldwork.
  • Identify connected rainforest, moist gullies, fallen timber, rocks, dense leaf litter and other ground cover that may provide shelter.
  • Treat a lack of records as a lack of survey evidence, not evidence that the species is absent.

Survey methodology: 2. Field detection

Use systematic visual searches through suitable rainforest habitat. Search the ground layer, leaf litter, fallen timber, rocks, dense vegetation and other natural shelters without unnecessarily disturbing habitat.

Search during warm, humid conditions when skinks are likely to be active. Include searches after suitable rain where safe access is possible. Avoid relying on a single visit or a single weather condition.

Use active searches, careful observation and targeted searches of likely shelter sites. Turn or lift cover only where authorised, and replace it exactly as found.

  • Walk slowly through all proposed disturbance areas and the edges of retained rainforest.
  • Inspect crevices, the underside of loose natural cover and the base of fallen timber.
  • Use photographs and, where authorised, close examination to confirm identification.
  • Do not use trapping, pitfall arrays or other intensive methods unless they have been designed and approved by a suitably qualified ecologist and permitted by the relevant authority.

Survey methodology: 3. Identification and confirmation

Distinguish the orange-speckled forest-skink from similar Karma skinks. Check the arrangement of the secondary temporal scales, as the lower secondary temporal usually overlaps the upper secondary temporal in this species.

The species has six supralabials, with the fourth typically below and contacting the eye. Live animals have yellow to orange bellies, with females tending to be more yellow and males more orange. Colour alone is not sufficient for identification.

  • Photograph the head, side of the body, belly and whole animal where this can be done without harm.
  • Record the secondary temporal scales and supralabial arrangement in photographs or field notes.
  • Seek expert confirmation for uncertain records. Do not retain an animal for identification unless authorised.

Survey methodology: 4. Effort and conditions

There is no established species-specific survey protocol or known seasonal breeding or migration period. Scale survey effort to the size and condition of the habitat, the amount of clearing and the consequences of a missed animal.

Use more than one survey period where the site contains substantial rainforest or where the first visit is cool, dry, wet, windy or otherwise unsuitable for detection.

  • Record the date, start and finish times, weather, recent rainfall, observer names and survey conditions.
  • Record the route, area searched, search method, search effort and habitat condition.
  • Record all animals seen, signs of use, shelter sites, photographs, coordinates and the outcome of any identification check.
  • Document areas that could not be searched and explain why.

Before habitat disturbance: 1. Avoidance and approvals

Plan the works around avoidance first. Keep rainforest habitat intact wherever practicable, and confirm approvals, survey requirements and wildlife handling arrangements before clearing starts.

Redesign the footprint to retain rainforest, connected vegetation, ground cover and natural shelters. Avoid unnecessary access tracks, laydown areas and edge widening.

Confirm the current Queensland status of the orange-speckled forest-skink before works. Queensland lists it as Vulnerable. Check whether the action requires an EPBC Act referral or approval, and obtain any Queensland permits required under the Nature Conservation Act 1992.

  • Obtain written environmental approvals before clearing.
  • Use a qualified ecologist to prepare species-specific conditions for the project approval or environmental management plan.
  • Do not assume that a general fauna permit authorises capture, handling, relocation or habitat disturbance.
  • Where works may affect a breeding place, obtain Queensland advice on any required species management program or other approval before disturbance.

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

Complete a pre-clearance survey of the final disturbance footprint and the immediate edge shortly before works. Include all rainforest ground habitat and likely shelters.

Mark retained habitat, no-go areas and approved access routes on the ground. Install visible exclusion fencing where needed, without trapping animals inside the work area.

  • Search the footprint systematically under suitable warm and humid conditions.
  • Have a fauna spotter catcher or suitably qualified ecologist inspect likely shelters before machinery enters.
  • Close or modify access points that could direct animals into the clearing area.
  • Stop preparation works if an animal is found and the approved fauna procedure cannot be followed safely.

Before habitat disturbance: 3. Timing and work planning

Breeding timing has not been established for the orange-speckled forest-skink, and no migration pattern is documented. Do not rely on a seasonal clearance window as a substitute for survey and avoidance.

Plan clearing for periods when animals can be detected and safely moved, subject to weather, safety and approval conditions.

  • Avoid clearing during weather that prevents effective detection or safe handling.
  • Recheck the site if clearing is delayed for a substantial period or if habitat conditions change.
  • Stage works so that retained rainforest remains connected and animals have access to undisturbed cover.
  • Keep machinery, spoil and materials out of retained habitat and drainage lines.

Before habitat disturbance: 4. Induction and responsibilities

Give all workers a short fauna induction before entering the site. Explain the appearance of the orange-speckled forest-skink, the no-go areas, stop-work process and reporting chain.

Nominate one person with authority to direct fauna controls and stop work. Ensure the spotter catcher has the required authority and equipment before clearing begins.

  • Show workers photographs of the species and similar skinks.
  • Tell workers not to handle, chase, collect or relocate animals.
  • Display contact details for the spotter catcher, project environmental manager and wildlife carer or veterinarian.
  • Brief operators on staged clearing, exclusion fencing and the location of retained habitat.

During habitat disturbance: 1. Sequential clearing

Clear in a controlled sequence and keep a qualified fauna observer involved. The observer must be able to stop work immediately when an animal, shelter site or possible breeding place is encountered.

Clear progressively towards retained habitat so animals can move away from machinery into intact cover. Keep the work area as small as practicable and do not clear beyond the approved footprint.

Remove machinery and personnel from the immediate area when the spotter catcher calls a stop.

  • Start with low impact preparation and inspection of the footprint.
  • Search vegetation, leaf litter, fallen timber, rocks and other ground cover before removal.
  • Lower or move habitat carefully where practicable rather than crushing it in place.
  • Do not burn, bury or stockpile natural cover within retained habitat without approval.
  • Inspect each cleared section before moving machinery into the next section.

During habitat disturbance: 2. Handling and relocation

Only authorised and suitably trained people may capture, handle or relocate an orange-speckled forest-skink. Use the least stressful method available and keep handling brief.

Place a captured animal in a secure, ventilated container that is protected from heat, direct sun, flooding and predators. Do not place different animals together unless directed by an appropriately qualified person.

  • Record the capture location before moving the animal.
  • Move the animal only to an approved nearby area of suitable retained rainforest habitat, where relocation is authorised.
  • Release it into natural ground cover, away from machinery and active work.
  • Do not transport animals off site or keep them overnight unless specifically authorised.
  • Seek veterinary advice for animals that are injured, weak or unable to move normally.

During habitat disturbance: 3. Breeding places and occupied habitat

No species-specific breeding place type is established for the orange-speckled forest-skink. Treat any suspected nest, shelter with dependent young, occupied refuge or repeatedly used site as sensitive until assessed by the ecologist and regulator.

If a breeding place or dependent young are found, stop work in the immediate area and apply the approved species management procedure. Do not disturb, fill, block or move the site without approval.

  • Establish a temporary no-entry area around the find, with the size set by the qualified ecologist and approval conditions.
  • Keep machinery, vibration, spoil, chemicals and workers outside the exclusion area.
  • Record the location, habitat, photographs, animal condition and actions taken.
  • Resume work only when the spotter catcher and environmental manager confirm that controls are in place.

During habitat disturbance: 4. Injured or dead animals

Stop work near an injured animal and keep people, machinery and pets away. Allow the spotter catcher to assess it without unnecessary handling.

Use the project wildlife care pathway and contact a qualified wildlife carer or veterinarian. Do not release an injured animal without professional advice.

  • Record the location, apparent cause, condition and photographs where safe.
  • Place the animal in a secure container only if authorised and trained to do so.
  • Report deaths, injuries, unauthorised handling and escapes to the project environmental manager and relevant authority where required.
  • Preserve relevant evidence, such as photographs and machinery or work records, for incident review.

During habitat disturbance: 5. Daily records

Keep a fauna log for every clearing shift. Records should allow the project team and regulator to reconstruct what was searched, what was found and how each animal was managed.

  • Record date, work area, weather, personnel, machinery, survey effort and clearing sequence.
  • Record all sightings, captures, relocations, breeding place observations, injuries, deaths and stop-work events.
  • Record permits, approvals, release locations, photographs and the names of people who handled animals.
  • Report unexpected findings to the environmental manager before work continues.

After habitat disturbance: 1. Post-clearance inspection

Post-clearance checks confirm that animals, shelters and exclusion controls have been managed properly. Review each incident promptly and use the results to improve the next work stage.

Inspect the completed footprint and its retained edges after clearing. Look for animals sheltering under debris, in machinery areas, along exclusion fencing and at the boundary of retained rainforest.

Remove hazards such as open trenches, unsecured containers and material stockpiles that could trap or injure skinks.

  • Complete a final search before demobilising the fauna observer.
  • Check that no animal has been enclosed by fencing, spoil or temporary structures.
  • Search any area where clearing was interrupted or where an animal was last seen.
  • Document the inspection and close out outstanding fauna actions.

After habitat disturbance: 2. Relocated animals

Record every authorised relocation and the condition of the animal at release. Use the approved release location and retain the release information with the project fauna records.

Do not repeatedly recapture or move an animal unless required for safety, approval compliance or veterinary care.

  • Record the release date, location, habitat condition, method and observer.
  • Check that the release site contains intact rainforest ground cover and is outside active construction areas.
  • Report animals that cannot be located, are injured after release or return to the work area.
  • Use post-release checks only where required by approval conditions or the project monitoring plan.

After habitat disturbance: 3. Monitoring and reporting

Monitoring should match the Queensland Vulnerable listing, the size of the impact and the quality of retained habitat. Set the approach with the project ecologist and regulator rather than applying an untested fixed protocol.

Use repeat searches and habitat checks where the project removes or fragments rainforest habitat, affects a known record or has produced fauna incidents.

  • Monitor retained rainforest edges, access routes and rehabilitation areas under suitable survey conditions.
  • Use the same search method and recording format at each monitoring visit so results can be compared.
  • Report survey effort, detections, relocations, injuries, deaths, breeding place observations and habitat condition.
  • Submit reports and records required by approval conditions and permits.

After habitat disturbance: 4. Incident review

Review every stop-work event, injury, death, escape, unauthorised handling event and unexpected habitat impact. Include the spotter catcher, site supervisor and environmental manager in the review.

Update the clearing sequence, induction, exclusion controls and survey approach before the next work stage.

  • Identify what happened, when it happened, where it happened and which control failed.
  • Check whether machinery operation, weather, visibility, fencing or communication contributed.
  • Record corrective actions, responsible people and completion dates.
  • Escalate serious or repeated incidents to the relevant authority as required.

Rehabilitation actions: 1. Habitat restoration

Rehabilitation should rebuild connected rainforest ground habitat and reduce ongoing disturbance. The species is poorly known, so restoration should favour natural habitat features rather than untested artificial structures.

Restore cleared areas with locally appropriate rainforest species and a structurally varied ground layer. Prioritise connection with retained rainforest and protection from repeated disturbance.

Retain or reintroduce natural shelter features where safe, including leaf litter, fallen timber, rocks and dense low vegetation.

  • Use local provenance plants where practicable and suitable for the site.
  • Protect new plantings from machinery, grazing, fire and trampling.
  • Leave natural ground cover in place as it develops.
  • Avoid compacting soil and maintain natural drainage patterns.
  • Prevent rehabilitation areas from becoming isolated islands of vegetation.

Rehabilitation actions: 2. Artificial structures

No use of nest boxes, bat boxes, artificial nest sites or roost structures has been established for the orange-speckled forest-skink. Do not install these structures as a substitute for rainforest habitat.

If the project ecologist identifies a need for artificial shelter, design it specifically for a terrestrial rainforest skink and trial it only with regulator approval and a monitoring plan.

  • Prefer natural logs, rocks, leaf litter and vegetation over manufactured structures.
  • Do not install bat boxes, bird nest boxes or elevated roost structures for this species without evidence that they are suitable.
  • Inspect any approved artificial shelter for heat, flooding, predators, entrapment and maintenance problems.
  • Remove unsuccessful or hazardous structures under ecological advice.

Rehabilitation actions: 3. Weeds, fire and water

Control weeds that suppress rainforest regeneration or alter the ground layer. Use methods that avoid poisoning, burying or disturbing occupied shelter sites.

Maintain natural moisture conditions and drainage without creating water hazards or artificial ponds that are not part of the approved design.

  • Inspect rehabilitation areas for weed invasion and respond early.
  • Prevent sediment, concrete washout, fuels and chemicals from entering rainforest habitat or drainage lines.
  • Avoid broadscale herbicide use near retained ground cover unless approved and carefully controlled.
  • Use erosion and sediment controls throughout construction and until vegetation is established.
  • Do not use fire in or next to retained or rehabilitating rainforest unless specifically approved.

Rehabilitation actions: 4. Lighting and ongoing disturbance

Limit night lighting near retained rainforest and rehabilitation areas. The activity pattern of the orange-speckled forest-skink is poorly known, so avoid unnecessary illumination and disturbance.

Keep permanent infrastructure, vehicle movements and maintenance activities outside retained habitat wherever practicable.

  • Use the lowest practical light level and direct lights away from rainforest edges.
  • Use shields and timers to reduce light spill.
  • Avoid lighting that shines into ground cover, leaf litter and shelter areas.
  • Restrict vehicle access and keep rehabilitation areas clearly marked.

Rehabilitation actions: 5. Long-term monitoring

Monitor vegetation structure, ground cover, connectivity, weed control and fauna use for the period required by project approvals. Include repeat searches for the orange-speckled forest-skink where habitat has been restored or retained near works.

Adapt rehabilitation if ground cover is lost, weeds spread, drainage changes or construction impacts continue.

  • Record survey conditions, search effort, habitat condition and all detections using consistent methods.
  • Compare rehabilitation areas with nearby retained rainforest where suitable.
  • Maintain records of plant survival, shelter features, weeds, erosion, lighting and incidents.
  • Use monitoring results to guide further planting, weed control, access restrictions and maintenance.
  • Report failures and corrective actions through the project environmental reporting process.
