Cooloola Blind Snake (Anilios silvia)

Conservation status

Queensland, Nature Conservation Act 1992: Near threatened.

Breeding season

The breeding season of the Cooloola Blind Snake is poorly known. As a general guide for a Queensland blind snake, breeding and surface activity are more likely in the warmer months, with timing varying between years and locations. Its near threatened status warrants targeted pre-clearance surveys and careful management of soil disturbance.

Breeding mode: Not recorded for the Cooloola Blind Snake. Australian blind snakes generally lay eggs.

Clutch size: Not recorded.

Incubation period: Not recorded.

Hatching period: Not recorded.

Age at maturity: Not recorded.

Breeding sites: Not recorded. Avoid disturbing likely sheltering and breeding places during soil stripping, trenching and other ground works.

Breeding frequency: Not recorded.

The seasonal pattern is indicative only and may shift between years and regions, particularly with rainfall and temperature.

• Likely breeding activity: Breeding is not documented for this species, so this broad pattern is a general guide for a Queensland blind snake.
• Likely eggs and hatchlings: Egg and hatchling timing is not recorded, but young may occur during and after the warmer breeding period.
• Likely surface activity: Surface activity is likely to increase in warm or wet conditions, although the species may remain below ground for much of the year.
• Pre-clearance survey and protection focus: For this near threatened species, schedule targeted surveys before clearing where practicable and manage ground disturbance throughout the year, with extra care during warmer active months.
• Highest clearing risk: Risk is highest when breeding, eggs or young are most likely, but clearing can affect adults and underground shelter sites in any month.

Identification: Appearance

The Cooloola Blind Snake is a small, subterranean snake with a slender cylindrical body and strongly reduced eyes. It is poorly known in the field, so identification should be confirmed from clear photographs or by an experienced reptile ecologist.

Blind snakes are smooth-scaled, cylindrical snakes with a blunt head and a short tail. The eyes are very small and may be difficult to see. The striped blind snake name indicates that striping can be associated with this animal, but colour and pattern should not be used alone for identification.

Identification: Calls and similar species

No call or vocalisation is expected. Blind snakes do not use echolocation. Other small, slender snakes may be confused with this species, especially when viewed briefly or in poor light.

• Treat an unfamiliar small snake as potentially significant until it has been identified.
• Use photographs of the head, body pattern, tail and scale arrangement where safe to do so.
• Seek confirmation from a qualified ecologist or reptile specialist before release or relocation.

Identification: Field signs

Direct sightings are more likely during soil disturbance, after rain, or when ground cover and loose soil are moved. No species-specific information is available for droppings, nests, odour or other distinctive field signs.

• Inspect exposed soil, leaf litter, decaying timber, rock edges and spoil piles during clearing.
• Check buckets, trenches and other excavations regularly for trapped reptiles.
• Do not handle the animal unless authorised and trained to do so.

Distribution: Queensland range

The Cooloola Blind Snake is endemic to Queensland and is mapped in the Southeast Queensland bioregion. Current mapping for this profile is limited to Queensland, and there is no relevant overseas range.

The species is recorded from Southeast Queensland. The available regional information identifies it as naturally occurring in Queensland, but does not define a complete distribution across the state.

• Check WildNet and current regional mapping before works begin.
• Review records near the project area, including records close to the site boundary.
• Do not treat a lack of mapped records as proof that the species is absent.

Distribution: Site assessment

A project area can include suitable habitat even where no previous record is mapped. Records may be incomplete, and the species is difficult to detect because it spends much of its time below ground.

• Use a qualified ecologist to assess potential habitat during project planning.
• Update the assessment if clearing footprints, access tracks, stockpiles or excavation areas change.
• Keep accurate location, date, photographs and handling details for any encounter.

Habitat: Features to check

The species habitat requirements are poorly documented. For site work, give particular attention to undisturbed or lightly disturbed ground with loose soil, leaf litter and cover objects that could support a small burrowing reptile.

Inspect sandy or friable soil, soil beneath leaf litter, decomposing vegetation, fallen timber, rocks and the edges of natural ground cracks. Also assess drainage lines, low rises and other areas where soil structure and ground cover remain intact.

• Native vegetation with an intact ground layer.
• Loose soil beneath logs, bark, rocks and accumulated leaf litter.
• Bushland edges, regrowth areas and undisturbed patches between cleared areas.
• Temporary habitat in soil heaps, mulch and other stored ground material, where reptiles may shelter.

Habitat: Works planning

Retain connected patches of native ground cover where practicable. Limit the area of soil disturbance and avoid spreading spoil, mulch or cleared material into retained habitat.

• Mark no-go areas before clearing starts.
• Keep machinery and vehicle movements within defined work areas.
• Use staged clearing so fauna can move away from disturbance where suitable habitat remains connected.
• Have a fauna spotter catcher inspect active work areas and retained habitat edges.

Foraging habitat: Ground features

The diet and foraging habitat of the Cooloola Blind Snake are not well documented. Blind snakes generally forage below ground and are commonly associated with the nests and soil spaces of ants and termites, so soil disturbance can remove feeding opportunities as well as shelter.

Look for loose soil, fine root zones, leaf litter and decaying timber that support soil invertebrates. Ant and termite activity may indicate useful foraging conditions, although it does not confirm the presence of this species.

• Inspect beneath logs, bark, rocks and dense litter before these features are moved.
• Retain undisturbed soil and decomposing timber where they do not conflict with safety requirements.
• Avoid unnecessary compaction, sealing or removal of the natural ground layer.

Foraging habitat: Clearing practice

Move ground cover carefully and progressively. Work from already disturbed areas towards retained habitat where practicable, while ensuring that animals are not driven into active machinery areas.

• Keep a trained fauna spotter catcher present during ground disturbance.
• Pause work if a blind snake or other protected fauna is found.
• Place captured fauna in a suitable nearby release location selected by the fauna spotter catcher and approved under the project fauna management plan.
• Record the encounter and report it through the project’s environmental reporting process.

Breeding habitat: Potential breeding features

Breeding places and breeding timing for the Cooloola Blind Snake are not documented in the available regional profile. Avoid disturbing likely below-ground refuge areas and obtain project-specific ecological advice before clearing potential habitat.

As a small burrowing snake, the species may use protected soil spaces, deep leaf litter, decaying timber, rock cover or other sheltered ground features. These are precautionary assessment features, not confirmed breeding sites for this species.

• Inspect hollow logs, dense litter, loose soil and rock piles before removal.
• Treat occupied burrows, cracks and concealed soil spaces as potential fauna habitat.
• Avoid filling or collapsing burrows unless authorised under the project’s fauna procedures.

Breeding habitat: Timing and protection

No breeding months, clutch size or breeding place type is established in the available information. Do not rely on a seasonal clearing window to remove the need for a pre-clearance inspection.

• Complete a pre-clearance survey by a suitably qualified ecologist or fauna spotter catcher.
• Stop work if a suspected breeding place, eggs or dependent young are found.
• In Queensland, tampering with the breeding place of this Near threatened animal requires a species management program.
• Escalate any suspected breeding place to the relevant project environmental manager and Queensland regulatory contact.

Sheltering habitat: Shelter features

Sheltering habitat is likely to be mainly below ground or beneath ground cover, but species-specific shelter preferences are poorly known. Retain a range of natural cover features and inspect concealed spaces before disturbance.

Potential shelter includes loose soil, leaf litter, decaying timber, bark, rocks, root spaces and natural cracks. Trenches, pits and uncovered post holes can also trap animals and should not be left open without fauna controls.

• Search beneath movable cover before it is removed.
• Inspect excavations, pipe trenches, spoil heaps and material stacks each day.
• Provide ramps or fauna escape devices in open excavations where suitable.
• Backfill or cover excavations when they are no longer required.

Sheltering habitat: Handling and release

Blind snakes are delicate and can be injured by rough handling. Capture and relocation should be undertaken only by trained, authorised personnel using approved methods.

• Keep the animal out of direct sun and away from vibration and machinery.
• Do not place it in water or expose it to chemicals, dust or extreme heat.
• Release it promptly into suitable nearby cover, subject to the project fauna management plan and any approval conditions.
• Document the capture, temporary holding and release location.

Threats: Clearing and earthworks

The main project risks are likely to come from loss of ground habitat and direct injury during clearing and earthworks. Because the species is Near threatened and difficult to detect, apply precautionary controls even when no animal is found during a survey.

Clearing, grading, trenching, excavation and soil compaction can remove shelter, feeding areas and potential breeding places. Animals may be injured by machinery or buried in disturbed soil.

• Minimise the clearing footprint.
• Clearly mark retained vegetation and ground habitat.
• Use staged clearing and pre-clearance inspections.
• Keep fauna spotter catcher coverage during high-risk ground disturbance.

Threats: Trapping and construction hazards

Open trenches, pits, pipes, post holes and spoil piles can trap small reptiles. Sediment, concrete washout, chemicals and dust can also degrade ground habitat.

• Inspect excavations and artificial pits regularly.
• Cover or fence hazards when unattended.
• Use fauna escape ramps where appropriate.
• Keep fuels, chemicals, washout and waste away from retained habitat and drainage lines.

Threats: Habitat fragmentation and degradation

Removal of native ground cover, repeated vehicle movements, weed invasion and changes to soil structure can reduce habitat quality beyond the immediate clearing footprint.

• Retain connected native vegetation and natural ground cover.
• Restrict vehicles to approved access routes.
• Rehabilitate disturbed areas with suitable local native vegetation and ground cover.
• Prevent the spread of weeds and contaminated soil between work areas.

Threats: Survey and compliance response

For a Near threatened species, use a risk-based survey and management approach rather than relying on chance observations. Review current records and habitat mapping, and obtain advice from a qualified ecologist before works in potential habitat.

Queensland protection: Near threatened and protected wildlife under the Nature Conservation Act 1992

Breeding place requirement: Tampering with its breeding place requires a species management program in Queensland

• Complete a desktop review and site inspection during project design.
• Use targeted searches of ground cover, soil edges and excavation areas before and during clearing.
• Brief all machinery operators and spotter catchers on identification and stop-work procedures.
• Report records and suspected breeding places through the project’s environmental approval and incident processes.

Survey methodology: 1. Desktop assessment

The Cooloola Blind Snake is poorly known, so surveys should combine desktop assessment with careful searches of likely ground habitat. Plan fieldwork for warm, suitable conditions when blind snakes are more likely to be active near the soil surface.

Review current WildNet records, recent survey reports, aerial imagery, soil mapping and proposed clearing boundaries before finalising the work method.

Treat the absence of records as inconclusive. The species is known from Southeast Queensland, and records may be incomplete or spatially imprecise.

Map areas where soil disturbance, clearing, stockpiling, trenching or vehicle access could affect potential sheltering or breeding places.

• Check the current Queensland conservation status and any site-specific species management requirements.
• Confirm whether the action requires an EPBC Act referral by checking current Commonwealth listings and the proposed action's potential impacts.
• Engage a suitably experienced herpetologist where the site is within or near known records, or where major soil disturbance is proposed.

Survey methodology: 2. Targeted field searches

Search the proposed disturbance footprint and access areas before clearing. Use active searching of ground cover, loose debris, soil cracks, litter, decaying vegetation and other likely shelter sites where this can be done safely.

Use hand searches and careful lifting of cover objects rather than broad soil scraping. Replace each cover object in its original position after inspection.

Where safe and lawful, inspect exposed soil faces, shallow excavations and areas of recent ground disturbance. Blind snakes may be difficult to detect because they spend much of their time below ground.

• Work during warm conditions and avoid relying on cold, very wet or very dry conditions for a single clearance decision.
• Use a staged search that covers the full footprint, not just areas with existing records.
• Stop searching if handling the site would create a greater risk to people, animals or habitat.

Survey methodology: 3. Survey effort and conditions

There is no validated species-specific survey effort or seasonal detection window for the Cooloola Blind Snake. Set effort according to the size and complexity of the site, the amount of soil disturbance and the quality of available shelter habitat.

Use repeat searches when the first inspection is undertaken in unsuitable conditions, when records are nearby, or when clearing will remove extensive ground cover or soil habitat.

Coordinate survey timing with the clearing sequence so that searched areas are cleared soon afterwards. Repeat the inspection if the site is left undisturbed for an extended period or conditions change substantially.

• Record date, start and finish times, weather, recent rainfall, ground conditions and search personnel.
• Record the search method, area covered, cover objects inspected, excavations checked and any limitations on access.
• Keep a clear map or GPS track of searched and unsearched areas.

Survey methodology: 4. Records and identification

Record every sighting, including animals found outside the approved disturbance footprint. Photograph the animal in place where this can be done without delay or harm.

Record the location, habitat, substrate, shelter position, behaviour, condition and direction of movement. Record whether the animal was left in place or moved under authority.

Have a field reference available and arrange expert confirmation for uncertain records. Do not rely on a common name alone when submitting a record.

• Submit records to the relevant Queensland biodiversity database or project reporting system.
• Keep photographs, GPS data, field sheets, permits and chain of custody information with the project records.
• Report unexpected concentrations of animals or repeated discoveries to the project ecologist and regulator contact.

Before habitat disturbance: 1. Approvals and permits

Avoidance should be the first option because the species has a limited known distribution and its habitat requirements are not well resolved. Finalise approvals, survey results and the clearing method before machinery enters the site.

Check the current Queensland listing before work starts. The Cooloola Blind Snake is listed as near threatened in Queensland and is protected wildlife.

Confirm whether the proposed work could tamper with a breeding place. In Queensland, tampering with the breeding place of protected wildlife requires an approved species management program where applicable.

Obtain all relevant Queensland wildlife permits, authority to take or interfere with wildlife, and approvals for handling, salvage or relocation before work begins.

• Ask the project environmental adviser to check whether an EPBC Act referral is required. Do not assume Commonwealth approval is unnecessary without checking current listings and the action's impacts.
• Include permit conditions, approved methods and reporting obligations in the clearing plan.
• Keep copies of approvals available for the fauna spotter catcher and site supervisor.

Before habitat disturbance: 2. Avoidance and site layout

Retain known or potential habitat wherever practicable. Reduce the disturbance footprint, avoid unnecessary soil stripping and keep access routes within already disturbed areas.

Protect retained ground cover, soil layers, fallen timber and other shelter features from storage, vehicle movements and sediment deposition.

Use clearly marked no-go areas and physical exclusion fencing where retained habitat is close to the work area.

• Locate compounds, stockpiles, wash-down areas and laydown areas away from potential snake habitat.
• Prevent runoff, sediment, chemicals and spoil from entering retained habitat.
• Use a site-specific buffer around confirmed animals, breeding places or high-risk habitat where directed by the approval, ecologist or regulator.

Before habitat disturbance: 3. Pre-clearance survey and exclusion

Complete the approved pre-clearance inspection shortly before disturbance. Search the entire footprint, including vegetation removal areas, trench lines, access tracks and temporary work areas.

Use staged exclusion only where it will not force animals into unsuitable or hazardous areas. Do not install barriers that isolate an animal from shelter or create a trap.

Mark any confirmed animal location and keep machinery out until the authorised fauna handler has assessed it.

• Brief the fauna spotter catcher on the species, likely search locations, permit conditions and stop-work triggers.
• Inspect material that will be moved, including loose timber, debris, soil clods and stored vegetation.
• Do not excavate or rake likely shelter areas before the fauna spotter catcher has checked them.

Before habitat disturbance: 4. Timing and crew induction

There is no reliable breeding or migration calendar for this species. Do not assume that a particular month is risk-free. Plan work around suitable survey conditions and the outcome of the pre-clearance inspection.

Schedule high-risk soil disturbance when an experienced fauna spotter catcher is available for the full activity, including trenching and stockpile movement.

Induct all workers before clearing starts.

• Explain the identification features available to the project team, the requirement to stop work and the no-touch rule for unauthorised workers.
• Show workers the exclusion zones, fauna handling area, emergency contacts and reporting process.
• Tell workers never to kill, chase, collect or move a blind snake.

During habitat disturbance: 1. Sequential clearing

Clear in a controlled sequence from lower-risk areas towards retained habitat, while keeping the fauna spotter catcher in a position to inspect the next work area. The spotter catcher must have authority to stop work immediately.

Use the approved clearing direction and sequence. Remove vegetation and surface cover in stages, then inspect exposed ground before the next stage begins.

Keep machinery at low speed and stop for inspections around debris, soil piles, cracks, excavations and other potential shelter locations.

Do not bury, crush or roll over loose cover before it has been checked.

• Maintain communication between the operator, spotter catcher and site supervisor.
• Keep cleared material and spoil within approved areas and away from retained habitat.
• Suspend work during poor visibility, unsafe weather or conditions that prevent effective fauna detection.

During habitat disturbance: 2. Animal handling and stop-work response

Only an authorised person may handle or relocate a Cooloola Blind Snake. The fauna spotter catcher should first assess whether the animal can be left safely in place.

If an animal is found, stop work, establish an exclusion zone and prevent people and machinery from approaching it. Record its location before any approved movement.

Relocate an animal only under the relevant permit, species management program or other approval, and only to a suitable nearby location selected by the authorised ecologist.

• Do not use hooks, shovels, rakes, chemicals or improvised containers to catch the animal.
• Use clean, secure and escape-proof equipment that is suitable for a small fossorial snake.
• Keep handling time short and avoid exposure to heat, direct sun and unnecessary disturbance.

During habitat disturbance: 3. Breeding places and concentrations

If an active breeding place, suspected breeding place or concentration of animals is found, stop work in the affected area. Do not disturb soil, shelter, eggs or associated habitat until the project ecologist has assessed the site.

Contact the approval holder and regulator contact identified in the species management program or permit. Follow any required protection zone, inspection and authorisation process.

Do not resume work until the authorised person confirms that the approved controls are in place.

• Photograph and map the location without entering the exclusion area unnecessarily.
• Protect the site from machinery, pedestrians, vibration, spoil, runoff and unauthorised handling.
• Review the clearing sequence if the find indicates that nearby ground habitat also requires protection.

During habitat disturbance: 4. Injured or dead animals

Treat an injured animal as a wildlife incident. Stop nearby work and keep the animal secure from people, vehicles, dogs and direct sun.

Contact the project fauna ecologist and an authorised wildlife carer or veterinarian through the approved project pathway. Do not provide food, water or medication unless directed by a qualified wildlife professional.

If an animal dies, do not dispose of it. Photograph, label and retain it only as directed by the ecologist or regulator.

• Record the location, time, apparent cause, condition and people involved.
• Use a clean container with appropriate ventilation and a secure lid if temporary containment is authorised.
• Report any suspected injury from machinery, crushing or chemical exposure under the project's incident procedure.

During habitat disturbance: 5. Field records

Maintain a daily fauna register throughout clearing and construction. Record nil results as well as sightings and incidents.

Link each record to the relevant permit condition, work area and clearing stage.

Provide records to the project ecologist for inclusion in approval and environmental reporting.

• Record date, time, GPS location, weather, activity, observer, animal condition and action taken.
• Record the name and authority of the person who handled or relocated an animal.
• Retain photographs, maps, permits, inspection forms and incident reports.

After habitat disturbance: 1. Post-clearance checks

Complete a formal check after each clearing stage and before the area is released to construction. Use the results to confirm that animals, shelter features and exclusion controls have been dealt with under the approved method.

Inspect the completed work area, spoil piles, stored vegetation, trenches and access routes for animals that may have remained after clearing.

Check exclusion fencing and retained habitat for trapped or injured fauna. Remove hazards only when the fauna spotter catcher has confirmed that the area is clear.

Record the limits of the completed search and any areas that could not be inspected.

• Repeat the check after major changes to the work area or after previously inaccessible ground becomes exposed.
• Keep trenches and pits covered, ramped or inspected as required by the approval and site fauna plan.
• Do not release an area to machinery until the responsible fauna professional signs off the inspection.

After habitat disturbance: 2. Relocated animals

Check relocated animals as required by the permit or species management program. Use the approved release location and method only.

Record the release location, habitat condition, time, weather, animal condition and any follow-up observation.

Do not repeatedly recapture or move an animal unless directed by the authorised ecologist.

• Keep release sites free from machinery, stockpiles, lighting and unnecessary pedestrian traffic.
• Check that the release location is connected to suitable retained ground habitat where this is part of the approved method.
• Report mortality, repeated returns to the work area or unusual behaviour to the project ecologist.

After habitat disturbance: 3. Reporting and compliance

Prepare a completion report for each clearing stage and a final fauna report for the project. Compare the results with the approved clearing method and permit conditions.

Report all sightings, handling events, injuries, deaths, suspected breeding places, breaches and stop-work events through the required channels.

Update the site risk assessment when a new record changes the understanding of local habitat use.

• Include maps, photographs, search effort, weather, personnel, equipment and outcomes.
• Document any departure from the approved method and the corrective action taken.
• Provide records to the Queensland regulator where required by the permit or species management program.

After habitat disturbance: 4. Incident review

Review any unexpected find, injury, death or repeated detection before the next clearing stage. Include the operator, fauna spotter catcher, site supervisor and project ecologist.

Identify whether the survey timing, clearing sequence, exclusion controls, induction or machinery controls need to change.

Brief the crew on the revised controls before work resumes.

• Record the cause, immediate response and prevention measures.
• Increase supervision or specialist input where the project has repeated detections.
• Retain the review with the project's environmental management records.

Rehabilitation actions: 1. Restore soil and ground cover

Rehabilitation should restore functioning ground habitat rather than install structures designed for birds or bats. The species is fossorial and poorly known, so restoration should be guided by local reference sites and advice from a qualified herpetologist.

Retain and respread suitable topsoil and leaf litter from the site where this is allowed by the rehabilitation plan. Avoid compaction and unnecessary deep soil mixing.

Re-establish natural surface cover, including leaf litter, fallen timber and coarse woody debris where these occur in nearby reference habitat.

Use local native plants and locally appropriate soil treatments to restore shade, moisture and ground structure.

• Fence rehabilitation areas from vehicles, stock, grazing and unauthorised access.
• Do not burn, rake or repeatedly clear rehabilitated ground cover unless required for safety or approved maintenance.
• Manage erosion and sediment at the source so that restored soil and shelter are not buried or washed away.

Rehabilitation actions: 2. Artificial structures and habitat features

Nest boxes, bat boxes, artificial nest sites and roost structures are not a standard mitigation measure for the Cooloola Blind Snake. Do not install them as a substitute for retaining or restoring soil habitat.

Where habitat features are needed, use natural materials and designs recommended by a specialist familiar with fossorial reptiles. Any trial should have an approved purpose, location, monitoring method and maintenance plan.

Avoid placing logs, debris or soil piles where they create fire, pest, erosion or machinery hazards.

• Seek specialist advice before creating artificial shelter or breeding features.
• Use clean, local and disease-free materials where practical.
• Map all installed habitat features and include them in the maintenance plan.

Rehabilitation actions: 3. Weeds, water and site conditions

Control weeds before they form dense mats or alter soil structure. Use methods that minimise soil disturbance and avoid contaminating retained or rehabilitated habitat.

Manage drainage so that rehabilitation receives natural water inputs without prolonged inundation, erosion or polluted runoff.

Keep chemicals, fuels, concrete washout and sediment away from restored areas.

• Use targeted weed control and inspect for regrowth during routine maintenance.
• Avoid unnecessary irrigation, grading and soil movement once ground cover is established.
• Maintain natural shade and shelter conditions rather than introducing bright open surfaces.

Rehabilitation actions: 4. Lighting and construction effects

Limit lighting near retained and rehabilitated ground habitat. Use only the lighting needed for safety and compliance.

Direct lights away from ground cover, habitat edges and release areas. Avoid unnecessary night work near known records.

Control vibration, dust, runoff and vehicle access during construction and maintenance.

• Use directional, shielded lights and switch them off when they are not required.
• Keep temporary lighting and generators out of retained habitat.
• Repair damaged exclusion fencing and rehabilitation areas promptly.

Rehabilitation actions: 5. Long-term monitoring

Monitor rehabilitation for establishment of native ground cover, soil stability, weed invasion, compaction and use by fauna. Adapt the program if the site develops conditions that are unsuitable for fossorial reptiles.

Use the same mapped reference points and methods during each monitoring event so that changes can be compared over time.

Record any Cooloola Blind Snake sightings and submit verified records to the relevant Queensland database.

• Set monitoring duration and frequency through the approval, rehabilitation plan and specialist advice rather than relying on a generic schedule.
• Inspect after significant earthworks, erosion, fire, flooding or maintenance disturbance.
• Use monitoring results to refine weed control, access restrictions, soil treatments and future clearing methods.
