National Status |
Status and Criteria | Least Concern |
Assessment Date | 2015/06/10 |
Assessor(s) | L. von Staden |
Justification | Widespread across the Richtersveld, and although possibly threatened in some places, this species is not yet in danger of extinction. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | Northern Cape |
Range | Southern Namibia to the Richtersveld. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Western Gariep Hills Desert, Kahams Mountain Desert, Lower Gariep Alluvial Vegetation, Rooiberg Quartz Vygieveld, Central Richtersveld Mountain Shrubland, Western Gariep Lowland Desert, Richtersveld Sheet Wash Desert, Noms Mountain Desert, Rosyntjieberg Succulent Shrubland, Stinkfonteinberge Eastern Apron Shrubland, Eenriet Plains Succulent Shrubland, Umdaus Mountains Succulent Shrubland, Kosiesberg Succulent Shrubland |
Description | Quartz patches and lower rocky slopes, in full sunlight. |
Threats |
| The most severe threat to plant species in the Richtersveld is overgrazing, which has led to a loss of species diversity, shrub cover, as well as erosion in places. This species is not grazed, and is not dependent on shelter from nurse shrubs, and it has been recently recorded in areas affected by heavy overgrazing where other, more sensitive succulents are declining or have already disappeared. It is possibly threatened by erosion and trampling in some places. It is also likely to be targeted by succulent collectors, but the severity of collection pressure is not known. |
Population |
This species is widespread across the central and eastern Richtersveld, but is known from only a few, scattered collections. It is possibly under-sampled.

Population trend | Stable |
