Listed as Vulnerable as this species has an extent of occurrence of around 5,470 km2, it occurs in two locations both impacted by urban, industrial and coastal development, and there is an ongoing decline in the extent and quality of its habitat as a result of these processes.

Geographic Range [top]

Range Description:This species has a small coastal distribution south of Perth and west of the Darling Range, Western Australia, from Pinjarra south to Yallingup Brook (Wilson and Swan 2013, Cogger 2014).
Countries occurrence:
Australia (Western Australia)

Population [top]

Population:This species is known to be sparsely distributed across its range (Kay and Keogh 2012). It is locally relatively common. Widespread proposed coastal development is likely to lead to population declines across this species' range. It is probably in decline overall at present, but at a slower rate than projected once this development goes ahead.
Current Population Trend:Decreasing
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:This species is found in open Eucalypt and Banksia woodland on sandy coastal plain and coastal heath.
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: There is no known use or trade of this species.

Threats [top]

Major Threat(s): This species is under threat as it is found only in the Swan Coastal Plain subregion south of Perth, a region now under heavy development from population growth from Perth (Kay and Keogh 2012) for both residential and industrial development. Much of the coastal habitat within the species' range has been lost and future developments are planned over much of the remainder of the range, which will accelerate rates of habitat and population decline.

Conservation Actions [top]

Conservation Actions: There are no species specific conservation measures. This species' range does coincide with a number of protected areas, however many of these are small and may not retain suitable habitat. More survey work to clarify its ecological tolerances and distribution is required, as there are gaps within the currently-understood range where it may occur or have historically occurred, and it has only recently been recognized as a species distinct from Ctenotus labillardieri. This is listed as a Priority 3 species by the State Department of Parks and Wildlife.
