Assessment Date | 2007/04/20 |
Assessor(s) | D. Raimondo & R.C. Turner |
Justification | EOO 5520 km², a lowland species that has lost 96% of its habitat and several subpopulations to wheat cultivation, loss is continuing in many parts of its range. Remaining subpopulations are severely fragmented. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Malmesbury to False Bay, and Worcester. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Shale Renosterveld, Swartland Granite Renosterveld, Overberg Sandstone Fynbos, Hawequas Sandstone Fynbos, Elgin Shale Fynbos, Peninsula Granite Fynbos, Boland Granite Fynbos, Hangklip Sand Fynbos, Cape Flats Sand Fynbos, Atlantis Sand Fynbos, Lourensford Alluvium Fynbos, Swartland Alluvium Fynbos, Breede Alluvium Fynbos |
Description | Loamy soils derived from granites or coastal acid sand, often in slight seepages which are susceptible to drying out if rainfall is inadequate. |
Threats |
| Agriculture: 96% of this species' habitat has been transformed to wheat farms and vineyards over the past 70 years. There is ongoing transformation around the Paardeberg, Paarl, Malmesbury and the Upper Breede River Valley mostly for vineyards. |
