Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-02-08

Listed as Least Concern because, although the extent of occurrence is less than 20,000 km², and the potential impact of diamond mining remains to be quantified, there is, at present, no reason to believe that the species is declining, and it is present in areas entirely restricted to public access (and with extremely high protection).

Habitat and Ecology [top]

Habitat and Ecology:This species is found in areas of coastal sand dunes, and consolidated alluvial soils with mean annual rainfall less than 400 mm. It is a subterranean and largely solitary species. Between two and seven young are born after a gestation period of 52 days. The species has a generation length of two years.
Generation Length (years):2

Threats [top]

Major Threat(s): The species is threatened by some loss of habitat through diamond mining operations in the coastal range. Although mining is a threat, public access to these regions is entirely restricted.

Conservation Actions [top]

Conservation Actions: The species occurs within Sperrgebiet (Namibia), which, while lacking government protection, has a very high level of protection. Long-term population monitoring of this species is needed.
