Population [top]

Population: It is estimated to have a population size less than 50,000, but greater than 10,000. The low estimate is based on the relatively small known range of the species. There have been no observed recent declines in the population, apart from one population lost because of dam construction.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: The species inhabits woodland/grassland on cracking clay soils. It is found near permanent water. Its breeding biology is unknown.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The flooding of Lake Argyle created by a dam appears to have caused local population extinction. Surveys have failed to relocate it in the area. Otherwise, there are no threats to the species' habitat at present.

Conservation Actions [top]

Conservation Actions: Its range includes a national park in the Western Australia and Northern Territory border region (Keep River).
