National Status |
Status and Criteria | Critically Endangered B1ab(iii)+2ab(iii) |
Assessment Date | 2013/01/30 |
Assessor(s) | L. von Staden |
Justification | One known location is threatened by habitat degradation due to infrastructure development and competition from alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Breede River Valley between Worcester and Rawsonville. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Breede Alluvium Fynbos |
Description | Alluvial sands, on gentle slopes. |
Threats |
| This species is currently known from one small fragment. Parts of this site is already disturbed through gravel quarrying and road construction, and it is surrounded by crop fields as well as bordered by the Brandvlei Dam. It is potentially threatened by habitat loss to further infrastructure development as well as invasive alien plants spreading from the river valley below. This species may have been more widespread in the past, but was only recently discovered, and this subpopulation is quite likely the only one remaining as surrounding areas are extensively transformed, predominantly for vineyard cultivation. |
