|Scientific Name:||Bathyergus janetta|
|Species Authority:||Thomas & Schwann, 1904|
|Taxonomic Notes:||Ellerman et al. (1953) regarded this taxon as being only subspecifically distinct from the Cape Dune Mole-rat, Bathyergus suillus, but most authors regard it as a distinct species.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor/s:||Maree, S., Faulkes, C. & Griffin, M.|
|Reviewer/s:||Amori, G. (Small Nonvolant Mammal Red List Authority) & Cox, N. (Global Mammal Assessment Team)|
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 its presence in areas entirely restricted to public access (and with extremely high protection).
|Range Description:||This species has been recorded from southern Namibia and western South Africa. There are three isolated populations, one from Alexander Bay, Orange River, the second from Port Nolloth to Groen Rivier, and the third from Steinkopf to Kamieskroon and the Kamiesberg (South Africa). The species rarely occurs above 300 m asl.|

|Population:||Population densities of this species are greater inland, with up to 44 individuals per sq km.|
|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.|
|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:||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.|
