Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Woolley, P.
Reviewer(s): Lamoreux, J. & Hilton-Taylor, C. (Global Mammal Assessment Team)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
Previously published Red List assessments:
1996 Vulnerable (VU)
1994 Vulnerable (V)

Geographic Range [top]

Range Description: The Crest-tailed Mulgara is endemic to Australia, where it is known with certainty only from some of the desert regions along the border between the Northern Territory and South Australia. Because the re-recognition of D. blythi as a species has been so recent the identity of museum specimens must be re-checked before the true range limits of both it and D. cristicauda can be determined (Woolley 2005, 2008).
Countries occurrence:
Australia (Northern Territory, Queensland, Western Australia)

Population [top]

Population: This species has a wide known range (Woolley 2005; Masters 2008).
Current Population Trend: Stable
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: D. cristicauda is found primarily in Sandhill Canegrass (Zygochloa paradoxa) dominated dunes, with a vegetation cover less than 20%, Nitre Bush (Nitraria billardierei) grasslands (Foulkes and Canty 2000), and Sandhill Canegrass flats near salt lakes (J. Foulkes pers. comm.). Their burrows have been found on dunes (Woolley 1990) and at the base of Nitre Bush hummocks (Masters 2008). Relatively little is known of the biology of this species (see Woolley 2006), but the reproductive pattern is thought to be similar to that of D. blythi.
Systems: Terrestrial

Threats [top]

Major Threat(s): There are no known major threats to this species.

Conservation Actions [top]

Conservation Actions: This species is found in at least one protected area (e.g., Simpson Desert Regional Reserve). Research into its distribution, abundance, habitat requirements, and possible threats is needed.
