Assessment Date | 2014/04/10 |
Assessor(s) | L. von Staden |
Justification | EOO 5525 km², between 15 and 20 remaining locations continue to decline due to ongoing habitat loss and degradation, and competition from alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Tulbagh and Darling to the Cape Peninsula and Somerset West. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Granite Renosterveld, Swartland Alluvium Renosterveld, Peninsula Granite Fynbos, Boland Granite Fynbos, Atlantis Sand Fynbos, Swartland Alluvium Fynbos, Breede Alluvium Fynbos |
Description | Granite-derived sandy gravels. |
Threats |
| Less than 30% of this species' habitat remains after extensive loss to urban expansion (predominantly on the Cape Peninsula), and crop cultivation - mainly vineyards. Remaining subpopulations occur on small remnants of natural vegetation, and the large majority are threatened by competition from dense, unmanaged infestations of alien invasive plants, as well as habitat degradation due to overgrazing. Habitat loss to urban expansion and agriculture continues. |
Population |
A formerly abundant species that has declined extensively, but is still fairly common in remaining suitable habitat on the Cape lowlands. It continues to decline due to ongoing habitat loss and degradation.

Population trend | Decreasing |
