Assessor(s) | N.A. Helme & D. Raimondo |
Justification | EOO and AOO<1000 km², small, scattered subpopulations at nine known locations continue to decline due to alien plant invasion, coastal development, agriculture and sand quarrying. Only three subpopulations are protected within reserves. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Houwhoek to Agulhas. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Overberg Sandstone Fynbos, Kogelberg Sandstone Fynbos, Agulhas Limestone Fynbos, Boland Granite Fynbos, Hangklip Sand Fynbos |
Description | Coastal limestone and sandstone flats and slopes below 250 m. |
Threats |
| Aliens on the Agulhas plain are severe around Hagelkrall and in Kleinmond above Arabella Golf estate. Sand quarrying is a threat in Stanford and Kleinmond. Coastal development is threatened subpopulations throughout the species' range including golf estates e.g. Arabella. Agricultural developments, particularly vineyards and Proteas in the Heidehof and around Kleinmond are additional threat to this species. |
