Assessment Date | 2006/11/01 |
Assessor(s) | T. Trinder-Smith & D. Raimondo |
Justification | This species has an extent of occurrence (EOO) of 7000 km². Small, severely fragmented subpopulations on isolated renosterveld remnants continue to decline due to overgrazing, alien plant invasion and ongoing wheat and vineyard expansion. It therefore qualifies as Vulnerable under criterion B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | It is found from Potberg to Mossel Bay. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Mossel Bay Shale Renosterveld, Garden Route Shale Fynbos, Gouritz Valley Thicket |
Description | Plants grow in rocky outcrops on dolomitic soils in renosterveld. |
Threats |
| Agriculture is a severe past threat in the Lower Breede River area and more than 80% of habitat has been transformed to wheat farming in the past 60 years. Agricultural expansion continuing in the Albertinia area. Furthermore, many of the renosterveld fragments where this species occurs are over grazed by livestock. Urbanisation has been noted as threat in the Mosselbay area. There is also currently an ongoing threat of invasive alien plants to subpopulations along the lower Breede River and around Albertinia. |
