Status and Criteria | Endangered B1ab(i,ii,iii,iv,v) |
Assessment Date | 2014/07/21 |
Assessor(s) | C. Klak, D. Raimondo, N.A. Helme & L. von Staden |
Justification | An extremely rare species, with four small, isolated subpopulations remaining, within an EOO of 1916 km². The population is estimated to number fewer than 1000 mature individuals, and continues to decline due to ongoing habitat loss and degradation on the Cape Flats and eastwards to Uilkraalsmond. About 80% of the remaining population occurs in one subpopulation, with other subpopulations consisting of fewer than 50 mature individuals, and therefore it is not considered severely fragmented. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Cape Peninsula to Uilkraalsmond. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Overberg Dune Strandveld, Cape Flats Dune Strandveld, Cape Seashore Vegetation |
Description | Limestone outcrops among dunes close to the coast. |
Threats |
| Threatened by habitat loss to urban expansion, coastal development and competition from alien invasive plants. |
Population |
Numerous historical records indicate that this species was once common on the Cape Flats, but it has now become extremely rare due to extensive habitat loss and degradation. Currently, three small, isolated subpopulations remain between Cape Point and Macassar: the largest, at Cape Point, consists of at least 800 mature individuals, and does not appear to be declining (J. Deacon pers. obs. 2014), however, the others consist of fewer than 50 mature individuals, and continue to decline due to ongoing habitat loss and degradation. A fourth subpopulation was recorded at Uilkraalsmond in 2003.
