Justification
This species is rare in South Africa, where it is known from fewer than 10 locations within a restricted range (national EOO 2446 km²), and is declining due to severe overgrazing. The South African population is continuous with Namibia, where this species is common and not threatened. The South African national status is therefore downgraded by one category due to potential rescue effects from the adjacent Namibian population, as per IUCN regional assessment procedures.
Distribution
Endemism
Not endemic to South Africa
Provincial distribution
Northern Cape
Range
Widespread across western Namibia, southwards to the lower Gariep River Valley, between Alexander Bay and Vioolsdrif, Richtersveld, South Africa.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Desert
Description
Rocky hillsides and dry riverbeds, usually in shade.
Threats
This species is threatened by overgrazing, with field observations indicating that livestock browse plants down to ground level on sandy flats in dry river courses. Individuals sometimes occur on near-vertical cliffs, where they are presumably safe from grazing. This species is not threatened in Namibia.
Population

This species has been rarely recorded in South Africa, but is widespread and common in Namibia. The South African population is declining in the western part of its range.
