Assessment Date | 2016/01/13 |
Assessor(s) | L. von Staden |
Justification | EOO 1884 km², known from six locations, but possibly occurring at more. It continues to decline due to ongoing habitat loss to rooibos tea and potato cultivation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Gifberg to Graafwater. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Olifants Sandstone Fynbos, Graafwater Sandstone Fynbos, Bokkeveld Sandstone Fynbos, Leipoldtville Sand Fynbos |
Description | Sandstone slopes and flats. |
Threats |
| Subpopulations on deep sandy flats are threatened by rapid, ongoing habitat loss to agricultural expansion, mainly potato and rooibos tea cultivation. |
Population |
A very rarely recorded species, but possibly overlooked. Very little of its habitat on the coastal sandy flats remain, and if more subpopulations exist, they are likely to be threatened and declining.
