Family | BRASSICACEAE |
Synonyms | Thlaspeocarpa namaquensis Marais |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2015/05/17 |
Assessor(s) | D. Raimondo & L. von Staden |
Justification | A rare, range-restricted species, known from four locations and potentially threatened by overgrazing. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | Richtersveld, Helskloof to Steinkopf. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Anenous Plateau Shrubland, Central Richtersveld Mountain Shrubland, Stinkfonteinberge Quartzite Fynbos |
Description | Stony slopes. |
Threats |
This species occurs mostly on upper slopes, where the grazing pressure is currently low. However, as rangelands on the plains and closer to settlements are becoming increasingly degraded, herders are starting to move their livestock into the mountains in search of grazing. This species is potentially vulnerable to increasing grazing pressure. |
Population |
This is a rare and poorly known species, recorded from four widely scattered locations along the central mountains of the Richtersveld.

Population trend | Stable |
