Status and Criteria | Near Threatened B1ab(iii,v) |
Assessment Date | 2014/09/30 |
Assessor(s) | P. Goldblatt, J.C. Manning & L. von Staden |
Justification | A range-restricted (EOO 2537 km²), but still fairly common species, known to occur at between 15 and 20 locations, and declining due to ongoing habitat loss to agricultural expansion. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Gifberg, Olifants River Valley and sandveld between Leipoldtville and Eendekuil. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Fynbos |
Description | Well-drained sandy and stony soil. |
Threats |
| On the Gifberg, Olifants River Valley and in the sandveld this species is threatened by ongoing habitat loss to agricultural expansion, predominantly for the cultivation of citrus, rooibos tea and potatoes. About 40% of sandy areas within its known range are currently irreversibly modified. Many subpopulations however occur on rocky slopes unsuitable to ploughing, and this species' habitat is also well-protected within the western parts of the Cederberg Wilderness Area, where it is fairly common between Pakhuis Pass and Citrusdal. |
