Geographic Range [top]

Range Description: This species is endemic to Australia where it is restricted to coastal areas in north-eastern Arnhem Land and Groote Eylandt in Northern Territory. The type specimen was reportedly collected on the Cape York Peninsula, Queensland some time prior to 1867, however, the species has not since been recorded here (Winter and Allison 1980; Lee 1995; Woinarski and Flannery 2008). There is a possibility that it is found in northern Queensland. There is one isolated record from Maningrida, north-central Arnhem Land, but the area of suitable habitat around this record is limited (J. Woinarski pers. comm.).

Population [top]

Population: It is common in suitable habitat, but its habitat is limited (Woinarski and Flannery 2008).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It occurs in a range of vegetation types on sandy substrates (J. Woinarski pers. comm.). It is patchily distributed, but appears to be most abundant in dunes and sandsheets, supporting coastal heathlands, shrublands, and tussock grasses (Woinarski et al. 1999; Woinarski and Flannery 2008). This species is difficult to trap, and is most easily detected by its tracks (Woinarski 2005). The gestation period is about seven weeks, and the females can give birth to up to five young (Woinarski and Flannery 2008).
Systems: Terrestrial

Threats [top]

Major Threat(s): The threats to this species are not known. Feral cats, strip-mining for manganese, and changes in the fire regime are possible threats.

Conservation Actions [top]

Conservation Actions: It is not present in any national parks, however, Cape Arnhem is an Indigenous Protected Area managed by the Dhimurru Land Management Aboriginal Corporation, and much of its range on Groote Eylandt is also proposed as an Indigenous Protected Area (J. Woinarski pers. comm.). There is a need to establish a monitoring program for this species. More information is needed about threats to this species.
