Assessor(s) | K.E. Steiner, D. Raimondo, L. von Staden & P.C.V. Van Wyk |
Justification | EOO 8304 km², plants at between five and 10 locations continue to decline due to overgrazing and habitat loss to mining. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | Alexander Bay to Hondeklipbaai. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Namaqualand Inland Duneveld, Namaqualand Coastal Duneveld, Namaqualand Strandveld, Richtersveld Red Duneveld, Southern Richtersveld Yellow Duneveld, Northern Richtersveld Yellow Duneveld, Namaqualand Arid Grassland, Richtersveld Coastal Duneveld, Namaqualand Sand Fynbos |
Description | Sandy areas near the coast. |
Threats |
| Threatened by severe overgrazing on the coastal plain on the Richtersveld. Nemesia species are highly palatable (J.H. Vlok pers. comm.), and this species has become very rare in the Richtersveld as a result of overgrazing, On the coast between Port Nolloth and Hondeklipbaai, open-cast mining is causing severe, ongoing habitat destruction and degradation. |
Population |
This species is extremely rarely seen (K.E. Steiner pers. comm.). Searches over many years in the Richtersveld have failed to locate any individuals (P.C.V. van Wyk pers. comm.). Most recent records are from the Namaqua National Park, where this species' habitat is protected, and the largest subpopulation remains. Elsewhere it is declining due to ongoing habitat loss and degradation.
