Lined Earless Dragon (Tympanocryptis petersi)

The Lined Earless Dragon is a small, ground dwelling agamid of southern Australia. It occurs in open grassland, chenopod and samphire shrublands, salt lake margins, claypans and dry coastal scrub, where clearing, grazing, fragmentation and altered water regimes can remove habitat and shelter sites. It may be encountered during vegetation removal, earthworks, road construction and works near saline or gypseous ground.

Conservation status

Victoria, Flora and Fauna Guarantee Act 1988: Endangered.

Breeding season

The likely breeding cycle runs from spring mating to late spring or early summer egg laying, followed by hatching from late summer into autumn. Clearing is most likely to harm the species from spring through autumn because females, eggs, hatchlings and young may be present, while shelter damage can affect animals using ground refuges.

Reproductive mode: Egg laying. Species-specific reproductive observations are limited.

Clutch size: Six eggs have been reported from one female. Related grassland earless dragons lay up to five eggs per clutch.

Incubation: Not recorded for the Lined Earless Dragon. Related grassland earless dragons have an incubation period of 40 to 70 days.

Size at hatching: Not recorded for the Lined Earless Dragon. Related grassland earless dragon hatchlings weigh as little as 0.6 grams and measure around 3 cm.

Age at maturity: Not recorded.

Nest or egg sites: Species-specific sites are not recorded. Related grassland earless dragons use invertebrate burrows, including wolf spider burrows, and shallow scrapes covered with loose soil or small debris.

Breeding frequency: Not confirmed for this species. Two clutches in a year are considered possible, and related grassland earless dragons may produce a second clutch when conditions are favourable.

Confirm timing at each site before works, because rainfall and temperature can affect activity, egg development and hatching, and timing may vary between populations.

  • Mating: Mating is likely in spring, from September to November. The documents do not identify a peak month for this species.
  • Gravid females: The timing is not confirmed for this species. Related grassland earless dragons have had gravid females recorded from September to January.
  • Egg laying: Egg laying is likely in late spring or early summer, mainly November and December, with some timing possibly extending into January. Six eggs have been reported from one female, but the species-specific clutch range is not known.
  • Incubation: Species-specific incubation timing is not recorded. Based on related grassland earless dragons, eggs may remain in nests or soil for 40 to 70 days after late spring or early summer laying, extending from November to March.
  • Hatchlings: Hatching is likely in summer for this species. Related grassland earless dragons emerge mainly from late summer through autumn, so hatchlings may be present from February to May.
  • Active period: No species-specific active season is recorded. As a practical guide, related grassland earless dragons should be treated as most likely to be surface active from spring through autumn, with activity also possible in late summer and early autumn.
  • Highest clearing risk: Risk is highest from September to February, when mating, gravid females, eggs or incubation may occur, and remains elevated from February to May while hatchlings and young emerge. Soil disturbance can also destroy burrows and other ground refuges used by related grassland earless dragons.

Identification

This is a small, cryptically coloured earless dragon with a depressed body, keeled scales and a lined dorsal pattern. It has no external ear opening and is most reliably identified by its combination of scalation, body pattern and absence of a lateral skin fold.

The body is usually reddish brown, grey brown or pale brown, with five dark transverse bands and a five lined pattern. The pale dorsolateral lines are usually as wide as, or wider than, the vertebral line. A contrasting pale bar is usually present above the eyes. The venter is white and may be immaculate or show brown flecking, especially on the throat and in eastern populations.

The head and snout have strongly keeled scales. The lateral neck fold is well developed and bears spines, but the lateral skin fold between the forelimb and hindlimb is absent. The body has scattered enlarged, spinous dorsal scales, which are often denser in the dark cross bands.

Snout to vent length: Females to 59 mm and males to 54 mm in the species description; Victorian animals to about 62 mm.

External ear: Absent or hidden, giving the genus its common name.

Dorsal bands: Usually five dark transverse bands.

Lateral skin fold: Absent between the axilla and groin.

Identification: Sex and geographic variation

Breeding males develop yellow on the throat, and the pale dorsolateral lines may become yellow suffused. Females are generally less contrasting, with more broken dorsolateral lines and weaker lateral lines.

Eastern and southern animals tend to have stronger patterning. Northern and western animals more often have interrupted lines and lower pattern contrast. The belly may be strongly peppered in eastern animals but is commonly white in other populations.

Identification: Similar earless dragons and field signs

Tympanocryptis pinguicolla has a lateral skin fold, always smooth ventral scales and commonly six or seven dark dorsal bands. It is associated with higher rainfall grassland, whereas eastern Lined Earless Dragons use more semi arid salt lake and mallee habitats.

Tympanocryptis houstoni has a vertebral line clearly wider than the dorsolateral lines, more than five bands in some individuals and heavier black flecking across the underside. Tympanocryptis argillosa can approach the species near Lake Frome and the eastern South Australian border, while T. tolleyi contacts it in the Gawler Ranges. Identification in these contact areas may require genetic or specialist morphological assessment.

The supplied documents do not describe reliable species specific tracks, scats, calls, sloughs or eyeshine. Nocturnal spotlighting is not indicated by the available biology, as the species is diurnal. Capture records, photographs and habitat context are more useful than indirect signs.

  • Treat small, lined, ground dwelling dragons found during clearing as potential Lined Earless Dragons until an experienced herpetologist confirms the identification.
  • Photograph the dorsal pattern, head, throat, underside, lateral fold and exact location before release where handling is authorised.

Distribution: National range

The species is endemic to southern Australia. The revised taxonomy restricted it from the much broader former concept of Tympanocryptis lineata, so historic records labelled T. lineata need careful review.

The current range includes northwestern Victoria, southeastern South Australia and southwestern New South Wales. South Australian records extend from the Adelaide and Mount Lofty region through chenopod and saline country, including the Eyre Peninsula, and towards the contact zones near Lake Frome and Lake Blanche.

In Victoria, the species is known from the Mallee and nearby saline or gypseous areas, including the Big Desert, Hattah and Lake Tyrrell. The available sources do not provide a complete, current state by state locality list for New South Wales.

States recorded: South Australia, Victoria and New South Wales.

Known bioregional settings: Victorian Mallee and Pine-Buloke Woodland ecosystems, South Australian chenopod shrublands and saline or gypseous country, and open grassland and dry scrub habitats.

Distribution: Strongholds and subpopulations

The species is reported to be relatively common on the southern Eyre Peninsula in South Australia. In contrast, only a few eastern South Australian areas are known to retain the species, and many mapped localities are based on historic museum specimens with no recent records.

Victoria contains very few known sites. The Victorian assessment describes small, disconnected subpopulations, while the 2019 review states that the species was then known from only five Victorian sites. A single historical Big Desert record was not repeated by extensive trapping between 2015 and 2018.

Victorian sites: Five sites were reported in the 2019 review, although the Victorian assessment describes the current range more generally as a small number of localities.

Victorian locations: Three locations were estimated for threatened species assessment purposes.

Connectivity: Victorian subpopulations are considered severely fragmented.

Distribution: Population size and trend

No total population estimate is provided. The species has declined across much of its range, with habitat loss, vegetation change and fragmentation particularly affecting Victorian and eastern populations.

The Victorian assessment found insufficient information to determine the number of mature individuals or to apply a quantitative population analysis. It recorded continuing decline in distribution, habitat quality, fragmentation and likely population status indicators.

Victorian extent of occurrence: 6,360 km², based on accepted post-1970 Victorian Biodiversity Atlas records.

Victorian area of occupancy: 28 km², based on 2 km by 2 km grids derived from accepted post-1970 records.

Recent population estimate: Not available.

Habitat: Habitat types

The Lined Earless Dragon uses open, warm temperate, semi arid and arid habitats. It is generally associated with low open vegetation and saline, gypseous or clay rich ground rather than dense woodland.

Recorded habitats include open grassland, chenopod shrubland, samphire and saltbush shrubland, salt lake margins, claypans and coastal dry scrubland. In Victoria, most populations occur in or near saline or gypseous areas within Mallee and Pine-Buloke Woodland ecosystems.

The species appears to avoid dense tree overstorey. In northwestern Victoria it is mainly associated with salt lakes and open shrublands, including areas around Lake Tyrrell and Hattah.

Vegetation structure: Open, low vegetation with little dense overstorey.

Substrate and landform: Saline, gypseous, claypan and salt lake margin habitats are important settings.

Climate: Warm temperate, semi arid and arid climates are represented in the range.

Habitat: Features to retain during works

Retain connected patches of native grassland, chenopod, samphire and saltbush vegetation, together with undisturbed saline or gypseous ground. Avoid creating isolated habitat patches where works can be staged around existing native vegetation.

Avoid unnecessary changes to drainage and surface water around salt lakes, claypans and irrigation influenced areas. The species has been affected by changed water regimes along the Murray Darling irrigation system.

  • Before clearing, map open native vegetation, saline depressions, claypans, gypseous ground, fallen timber and surface refuge features.
  • Keep machinery and spoil out of retained habitat and avoid compacting ground that may contain arthropod burrows.

Foraging habitat: Diet and feeding

The species feeds during the day on small invertebrates. The supplied documents do not identify particular prey taxa, food plants or a measured foraging range.

The Lined Earless Dragon is an insectivorous ground dwelling lizard that feeds on small invertebrates. It is diurnal and may bask on fallen timber or shrubs before or between feeding activity.

No species specific prey list, feeding rate, foraging density or home range has been provided. Food availability is therefore likely to depend on retaining native ground vegetation, litter, surface refuges and the invertebrate community in open saline and chenopod habitats.

Diet: Small invertebrates.

Foraging period: Daytime.

Measured foraging range: Not reported.

Foraging habitat: Foraging habitat management

Maintain a patchwork of low native vegetation and open ground rather than clearing all cover to a uniform surface. Avoid broad scale pesticide use where it could reduce small invertebrate prey, although the supplied documents do not quantify pesticide effects for this species.

Retain fallen timber and shrubs used for basking, and avoid repeated vehicle movement across likely feeding areas.

  • Schedule inspections of open saline, chenopod and grassland habitat before clearing, particularly around retained vegetation and surface refuges.
  • Use fauna spotter catchers experienced with small cryptic agamids during disturbance of suitable habitat.

Breeding habitat: Breeding biology

The species is oviparous. Available information indicates spring mating, late spring egg laying and summer hatching, but several reproductive details remain unknown.

Females lay eggs. A female carrying six eggs has been reported. Mating is likely in spring, egg laying is likely in late spring and hatching is likely in summer. Some females may produce two clutches in a year, but this is presented as a possibility rather than a confirmed population wide pattern.

The documents do not provide a confirmed incubation period, age at maturity or maximum wild lifespan. Generation length is estimated at 1 to 2 years.

Breeding season: Likely mating in spring, laying in late spring and hatching in summer.

Reproductive mode: Egg laying.

Clutch size: Six eggs have been reported from one female.

Incubation: Not reported in the supplied documents.

Age at maturity: Not reported in the supplied documents.

Lifespan: Not reported. Generation length is estimated at 1 to 2 years.

Breeding habitat: Breeding habitat

Breeding habitat is expected to occur within the same open grassland, chenopod, samphire, saltbush, salt lake margin and gypseous habitats used by adults. Retaining undisturbed ground is important because earthworks, grading and compaction can remove nest sites and small thermal refuges.

The supplied documents do not identify a species specific nest chamber, nest depth or preferred soil moisture. In related grassland earless dragons, arthropod burrows and other protected ground refuges are used for shelter and may also provide suitable breeding sites.

  • Avoid clearing suitable habitat during spring and summer where practicable, particularly around open saline or gypseous ground and known records.
  • Inspect and manage disturbed ground under an approved fauna handling procedure because eggs and small hatchlings may be difficult to detect.

Sheltering habitat: Likely refuges

The species is small, cryptic and ground dwelling. Specific shelter dimensions are not available, but related earless dragons use burrows and surface refuges that can be damaged by soil disturbance and compaction.

The supplied species account does not specify a den, burrow or shelter size for T. petersi. General information for grassland earless dragons identifies abandoned arthropod burrows, surface rocks and similar refuges as important thermal and predator refuges.

In suitable Lined Earless Dragon habitat, retain fallen timber, shrubs, surface rocks, native ground cover and undisturbed soil, especially where these features occur close to saline or gypseous vegetation.

Confirmed species specific refuge size: Not reported.

Refuges documented for related grassland earless dragons: Abandoned arthropod burrows, surface rocks and other similar ground refuges.

Recorded basking sites: Fallen timber or shrubs.

Sheltering habitat: Construction controls

Ploughing, grading, trenching and vehicle compaction may destroy arthropod burrows and other ground refuges. This is a particular concern where open native habitat is being converted or where temporary access tracks cross retained vegetation.

Provide a clear fauna handling and release procedure for animals found in shelters or under surface cover. Do not relocate animals beyond suitable habitat without the required approval.

  • Mark and avoid surface rocks, fallen timber, shrubs and visible arthropod burrows within retained habitat.
  • Minimise the width and duration of access tracks through suitable habitat.
  • Inspect excavations, spoil areas and disturbed ground for small cryptic lizards during active works.

Threats: Habitat loss and fragmentation

The main risks are habitat loss, fragmentation and degradation in open saline, chenopod and grassland habitats. Construction can add direct mortality through clearing, soil disturbance, vehicle movement and destruction of shelter sites.

Land clearing for agriculture, horticulture and development has reduced habitat across the range. In Victoria, vegetation change, grazing and fragmentation have severely affected chenopod shrublands associated with salinas and gypseous areas.

Salt and gypsum harvesting may damage habitat. Changed water regimes along the Murray Darling irrigation system have also affected habitat. Fragmented subpopulations have limited connectivity and limited dispersal ability.

  • Avoid clearing native open vegetation around saline and gypseous areas where an alternative alignment or work footprint is available.
  • Retain habitat links between known or potentially occupied patches.
  • Do not treat apparently bare saline or claypan ground as low value without checking for suitable habitat and records.

Threats: Direct works and vehicles

Clearing, earthworks, ploughing and compaction can kill animals, destroy eggs and remove arthropod burrows. Off road vehicles are identified as a threat in Victoria.

Roads, access tracks and construction traffic can cause direct mortality and can separate small subpopulations. The supplied documents do not provide a measured road mortality rate or road crossing distance.

  • Use pre-clearance searches and a fauna spotter catcher during vegetation removal and ground disturbance.
  • Restrict vehicle movements to defined tracks and use low speed controls in suitable habitat.
  • Stage clearing so animals can move towards retained suitable habitat, where this is consistent with the approved fauna management method.

Threats: Grazing, predators, fire and climate

Domestic stock grazing degrades habitat and changes vegetation structure. Foxes and cats are identified predators. Climate change may affect animals and nest sites through hotter and drier conditions.

The supplied documents do not identify a disease affecting T. petersi or provide species specific fire thresholds. Related grassland earless dragons may survive short term disturbance from fire, but this should not be treated as evidence that repeated or intense fire is safe for Lined Earless Dragon habitat.

  • Control access by stock in retained habitat and prevent grazing of rehabilitation areas until vegetation is established.
  • Manage food and shelter for foxes and cats through the approved site pest management programme.
  • Do not burn or clear refuge habitat without species specific ecological advice and the required approvals.
  • Avoid altering drainage or water levels around saline depressions, salt lakes and claypans.

Survey methodology: 1. Diurnal habitat and visual searches

No species-specific survey guideline or prescribed survey effort was provided for the Lined Earless Dragon. Surveys should focus on open, ground-level habitat in north-western Victoria and comparable chenopod, saltbush, samphire, saline and gypseous sites, using the methods below and recording conditions and effort clearly.

Search during daylight when animals are likely to bask or move on the ground. Concentrate on grassland, samphire and saltbush shrubland near saline or gypseous areas, including fallen timber, shrubs, surface rocks, arthropod burrows and other ground refuges.

Walk slowly through all suitable habitat and inspect the ground, the bases of shrubs, fallen timber and basking surfaces. Record each observation with a GPS location, date, time, weather, habitat type and behaviour.

The species is small and cryptic, with a maximum snout to vent length of about 62 mm and a total length generally below 160 mm. Searchers should expect animals to be difficult to detect and should not treat a nil result as evidence of absence.

Activity information: Diurnal and ground dwelling; reported to bask on fallen timber or shrubs.

Maximum size: About 62 mm snout to vent length; total length generally less than 160 mm.

Survey methodology: 2. Targeted searches of refuges and ground features

Inspect surface rocks, fallen timber, low shrubs, litter, cracks and abandoned arthropod burrows where these features occur in suitable habitat. Do not destroy or unnecessarily disturb refuges during the search.

Map areas with high concentrations of refuges and mark features that may need protection during clearing. Pay particular attention to saline and gypseous patches, which are associated with Victorian records.

  • Search both open ground and the edges of low vegetation, because the species uses ground-level refuges and basking surfaces.
  • Record the type, number and location of refuge features inspected, along with the area searched and the number of observers.

Survey methodology: 3. Trapping and supplementary detection

Use trapping only under an approved fauna survey or management plan and under the relevant state wildlife authority conditions. The supplied documents do not provide a species-specific number of trap nights, trap-line length, survey area, trap type or required number of survey nights.

If trapping is justified, design the program around the species' small, ground-dwelling habits and the site's saline, gypseous, grassland or chenopod habitat. Check traps at the frequency required by the permit and animal ethics conditions, and provide suitable shade and protection from exposure.

Avoid placing traps where they may flood, overheat or expose animals to predators. Suspend or modify trapping when conditions are unsafe.

Species-specific effort in supplied documents: Not specified.

  • Report the trap type, number of traps, trap nights, checking interval, weather, ground conditions and any by-catch.
  • Use experienced reptile handlers and follow the approved handling, identification and release procedure.

Survey methodology: 4. Timing and survey conditions

Time surveys for warm, dry daylight conditions when small agamid lizards are likely to be active or basking, while following the project's approved survey plan and animal welfare requirements.

Consider the breeding period when planning disturbance. The available assessment infers spring mating, egg laying in late spring and hatching in summer, with possible production of two clutches in a year.

Avoid relying on a single visit, particularly where habitat is fragmented or records are historical. The Victorian assessment states that recent targeted survey and sustained monitoring have been limited.

Likely breeding period: Mating in spring, egg laying in late spring and hatching in summer.

Victorian survey context: The assessment reports limited recent targeted survey and no sustained monitoring.

  • Document temperature, rainfall, wind, cloud cover, recent fire, grazing, flooding and any other condition that could affect detection.
  • If conditions are unsuitable, record the reason and reschedule rather than reporting the site as adequately surveyed.

Survey methodology: Minimum effort and reporting

  • Prepare a site-specific survey plan because the supplied documents do not prescribe a minimum number of visits, nights, hours, trap nights, transect length or survey area for this species.
  • Survey every area of potential habitat that may be cleared, inundated, compacted, excavated or isolated, and include an appropriate surrounding area where works could affect refuges or movement.
  • Use a qualified ecologist or suitably experienced reptile surveyor to confirm the identification of any suspected Lined Earless Dragon.
  • Submit confirmed records and negative survey information, with survey effort and spatial data, to the relevant state wildlife database, including the Victorian Biodiversity Atlas where the work is in Victoria.
  • Retain field sheets, photographs, GPS tracks, trap records, weather data, permits, animal handling records and photographs of habitat features with the project environmental records.
  • Recheck the current species name and conservation status before works because the species was formerly recorded in Victoria as Tympanocryptis lineata.

Before habitat disturbance: Avoid and minimise habitat loss

Treat open saline, gypseous and chenopod or saltbush habitat as potential Lined Earless Dragon habitat, especially where it contains ground refuges. The Victorian assessment describes few, disconnected subpopulations and continuing decline associated with several threats.

Redesign the disturbance footprint to retain grassland, samphire, saltbush and chenopod vegetation, saline or gypseous patches, fallen timber, surface rocks, low shrubs and intact ground refuges.

Retain connected habitat between occupied or suitable patches wherever practicable. The Victorian assessment identifies subpopulations as few, disconnected and severely fragmented.

Keep vehicles, stockpiles, compounds, access tracks and drainage works out of retained habitat and avoid unnecessary soil disturbance that could damage arthropod burrows.

  • Use existing disturbed areas for access and compounds where possible.
  • Do not clear habitat merely because no animal was detected during a limited survey.
  • Prevent grazing, vehicle access and other avoidable disturbance in retained habitat during and after the works.

Before habitat disturbance: Approvals and project planning

Confirm the current EPBC Act status before works and make a referral if the project may have a significant impact on a nationally listed species. The supplied information identifies no EPBC listing for this species, but status must be checked against the current official list.

Confirm state approval, permit and wildlife handling requirements before survey, trapping, clearing or relocation. In Victoria, the taxon has been assessed as Endangered and was previously listed as Critically Endangered on the 2013 advisory list.

Prepare a fauna management plan that identifies habitat, survey results, avoidance measures, exclusion areas, handling authority, release sites, stop-work triggers and reporting requirements.

  • Use the current accepted name, Tympanocryptis petersi, in permits, plans, records and incident reports.
  • Consult the relevant state agency if a record is found outside the mapped project assumptions or if the project may affect a previously unknown population.

Before habitat disturbance: Prepare the site

Complete the pre-clearance survey immediately before disturbance, with the timing and method set by the approved fauna management plan.

Mark no-go areas, retained vegetation, saline and gypseous habitat, refuge concentrations, release areas and access routes on plans and on the ground.

Install exclusion fencing where it can keep machinery, vehicles and stock out of retained habitat without blocking essential movement between retained patches.

Brief all workers on the species' appearance, habitat, ground-dwelling behaviour, reporting process and stop-work requirements.

  • Use photographs and GPS locations to document marked habitat and exclusion fencing before clearing begins.
  • Check fencing and signs daily before machinery enters the work area.
  • Do not use exclusion fencing as a substitute for a survey or for approval to clear occupied habitat.

During habitat disturbance: Daily controls and machinery coordination

The Lined Earless Dragon is a small ground-dwelling lizard that may be concealed in vegetation, litter, burrows or other ground refuges. Keep a fauna spotter catcher present for relevant works and give them authority to stop machinery when an animal or habitat feature requires assessment.

Inspect the work area, exclusion fencing and marked habitat before starting each day.

Keep the fauna spotter catcher in direct communication with machinery operators and position the spotter where they can see the active clearing face and ground disturbance.

Clear progressively in small sections so the spotter can inspect exposed ground and refuges before machinery moves into the next section.

Use low-speed machinery movements near retained habitat and stop if visibility is reduced by dust, vegetation, darkness, heavy rain or unsafe conditions.

  • Stop machinery immediately when the spotter catcher calls stop, raises the agreed stop signal or identifies an animal, burrow, refuge or unexpected habitat risk.
  • Do not allow operators or other workers to handle the animal unless they are authorised under the project approval and wildlife permit.
  • Keep cleared material and machinery away from retained habitat and any approved release site.

During habitat disturbance: Handling animals and habitat features

If a Lined Earless Dragon is found, stop work, keep people and machinery back, photograph it if this can be done without delay or disturbance, and have the authorised fauna handler assess it.

Handle the animal only when necessary to prevent harm or to complete approved relocation. Use the method specified in the permit and fauna management plan.

Relocate an uninjured animal only to nearby retained habitat that has been assessed as suitable and is within the approved release area. Record the exact capture and release locations.

Place injured animals in a secure, ventilated container and arrange prompt assessment by an authorised wildlife carer or veterinarian under the project procedure.

  • Do not chase, pin, crush, expose or repeatedly handle the animal.
  • Do not move an animal across roads, cleared barriers or unsuitable habitat unless this is authorised in the fauna management plan.
  • Inspect and manage exposed logs, rocks, litter, low shrubs and burrows under spotter direction before removal or grading.
  • Treat soil ripping, grading, trenching and compaction as potential impacts on ground refuges and arthropod burrows.

During habitat disturbance: Stop-work triggers and records

Stop work in the affected area for any confirmed or suspected Lined Earless Dragon until the authorised ecologist or fauna spotter catcher has assessed the animal and approved the next step.

Stop work if clearing exposes a concentration of burrows or refuges, if exclusion fencing fails, or if machinery enters a marked no-go area.

Stop work and seek advice if the number or distribution of animals differs materially from the approved impact assessment.

  • Record the date, time, GPS location, observer, activity, habitat, animal condition, photographs, action taken, release location and the names of authorised handlers.
  • Record all injuries, deaths, escapes, by-catch, fencing breaches and unplanned habitat disturbance as incidents.
  • Notify the project manager and relevant regulator within the time required by the approval or permit.
  • Update the fauna management plan if repeated finds or unexpected habitat features show that the approved controls are not adequate.

After habitat disturbance: Post-clearance inspection

Post-clearance work should confirm that no animals remain exposed or trapped and that retained habitat and movement routes remain protected. Because the Victorian assessment identifies limited monitoring and continuing decline, project records should support future population knowledge.

Have the fauna spotter catcher inspect the cleared area, exposed soil, retained edges, stockpiles, trenches, drains and temporary exclusion fencing before the site is handed back to construction crews.

Check for trapped, injured or displaced animals and inspect any remaining burrows, logs, rocks and low shrubs affected by the works.

Close or cover trenches and other excavations at the end of each work period, or provide fauna escape measures approved by the fauna management plan.

  • Do not leave spoil, pipes, mesh, erosion-control materials or open pits where they can trap small ground-dwelling reptiles.
  • Remove temporary materials from retained habitat when they are no longer required.
  • Maintain fencing until the risk of machinery entry and secondary disturbance has ended.

After habitat disturbance: Monitoring and reporting

Monitor retained habitat, release areas and rehabilitation areas at the frequency and duration required by the approval, offset condition or fauna management plan.

Use the same mapped locations and methods where possible so that observations can be compared through time. Record searches that find no animals as well as confirmed records.

Report confirmed records, mortalities, injuries, relocations, habitat damage and control failures to the relevant state wildlife database and regulator where required.

  • Compare monitoring results with the approved success measures and investigate any decline in habitat condition or repeated animal incidents.
  • Provide the landholder or asset operator with maps showing retained habitat, release areas, access restrictions and ongoing maintenance duties.
  • Retain all monitoring data, photographs and incident records for the period required by the approval.

After habitat disturbance: Offsets and residual impacts

Assess whether residual impacts remain after avoidance, minimisation and rehabilitation measures. Apply any offset, conservation covenant or habitat protection condition required by the approval.

Do not use an offset as a reason to remove avoidable habitat or to proceed without an approved fauna management plan.

Ensure any offset or protection site supports the habitat types used by the species, including open grassland, chenopod, saltbush, samphire, saline or gypseous ground and suitable refuges.

  • Document the area and condition of habitat lost, retained, restored and protected.
  • Check that any proposed offset is not based only on broad vegetation mapping that misses small saline or gypseous habitat patches.

Rehabilitation actions: Restore habitat structure

Rehabilitation should recreate open, low-vegetation habitat with intact ground structure rather than dense tree cover. It should restore the small-scale refuges and saline or gypseous conditions associated with the species' known Victorian habitat where these can be reinstated safely.

Re-establish locally appropriate native grassland, chenopod, saltbush or samphire vegetation suited to the site's soil, salinity and hydrology.

Keep restored areas open and avoid creating a dense tree or shrub overstorey where this is inconsistent with the pre-disturbance habitat.

Reinstate suitable fallen timber, surface rocks, leaf litter and low shrub cover in a patchy arrangement, using clean local material where available.

Repair compacted ground and restore natural drainage without flooding or salinising retained habitat beyond its natural condition.

  • Protect restored ground from stock, vehicles and unauthorised access until vegetation and refuge features are established.
  • Do not import soil, rock, mulch or plant material that could introduce weeds, pathogens or unsuitable changes to soil salinity.
  • Use locally appropriate species selected by a qualified restoration ecologist rather than planting a generic tree mix.

Rehabilitation actions: Refuges, prey and predator control

Retain or reinstate natural ground refuges such as arthropod burrows, surface rocks, fallen timber and low shrubs where they are part of the site's habitat.

Do not fill or compact occupied or suitable burrows unless this is necessary for safety and has been approved.

Control foxes and cats in accordance with the land manager's pest management program, because predation by both is identified as a threat.

Manage grazing, weeds and off-road vehicle access so that ground cover and refuges are not progressively degraded.

  • Inspect restoration areas for burrow collapse, erosion, weed invasion, grazing damage, vehicle damage and predator activity.
  • Avoid broadscale removal of fallen timber or rocks during maintenance.
  • Use nest boxes or artificial hollows only where they are relevant to other approved fauna outcomes; the supplied documents do not identify tree hollows or nest boxes as Lined Earless Dragon habitat requirements.

Rehabilitation actions: Fire, water and success measures

Develop fire management with the land manager and ecological adviser so that fire does not remove all ground cover or refuges across a retained or restored patch at one time.

Manage water, drainage and irrigation changes to retain the site's appropriate saline, gypseous, claypan or salt-lake conditions without creating prolonged inundation in refuge areas.

Set success measures for survival of planted or regenerating native ground cover, retention of open habitat, functioning ground refuges, absence of new weed or predator impacts and protection from grazing and vehicles.

Monitor restored and retained areas during the period specified in the approval, with additional surveys if habitat condition declines or animals are recorded.

  • Use fixed photo points, GPS-mapped habitat features and repeatable ground inspections to document rehabilitation progress.
  • Record any Lined Earless Dragon observations and submit confirmed records to the relevant state wildlife database.
  • Review rehabilitation methods if monitoring shows that dense vegetation, soil compaction, altered drainage, weed growth or loss of refuges is reducing habitat suitability.
