Assessor(s) | L. von Staden |
Justification | This species is known from two locations within a very limited area (EOO 61 km²) in South Africa, where it is declining due to ongoing habitat loss and degradation. As the South African population is continuous with the larger and more stable Namibian population, the national status is downgraded by one category as per IUCN regional assessment procedures. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | Northern Cape |
Range | Southern Namibia, from Lüderitz southwards to the lower Gariep Valley, Richtersveld, Northern Cape. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Western Gariep Lowland Desert, Western Gariep Plains Desert |
Description | Sandy places in dry riverbeds and gravel plains. |
Threats |
| This species is threatened in South Africa by ongoing habitat loss to mining, as well as severe ongoing habitat degradation due to overstocking of livestock across its known range in South Africa. In Namibia, some subpopulations have been recorded in mining areas, but it is not as severely threatened as in South Africa. |
Population |
This species is rare and localized in South Africa, but more widespread and common in Namibia. The South African population is declining due to habitat loss and degradation, but the Namibian population is stable.
