Assessor(s) | A.L. Schutte-Vlok & D. Raimondo |
Justification | Once common on this Cape Peninsula, this species has lost the majority of its habitat to urban expansion. Between 30 and 50 subpopulations remain. The population has fewer than 10 000 individuals with subpopulations always being small (<250 individuals). Decline is ongoing due to urban expansion, particularly on the Vredenburg Peninsula. Subpopulations are also threatened by invasive alien plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Paardeberg to Saldanha and the Cape Peninsula. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Cape Flats Dune Strandveld, Langebaan Dune Strandveld, Saldanha Granite Strandveld, Swartland Shale Renosterveld, Peninsula Shale Renosterveld, Swartland Granite Renosterveld, Swartland Silcrete Renosterveld, Peninsula Sandstone Fynbos, Cape Winelands Shale Fynbos, Peninsula Shale Fynbos, Peninsula Granite Fynbos, Boland Granite Fynbos, Hangklip Sand Fynbos, Cape Flats Sand Fynbos, Atlantis Sand Fynbos |
Description | Granite outcrops on well-drained, humic, sandy loams below 500 m. |
Threats |
| Competition from alien invasive plants is an ongoing threat to most remaining subpopulations. On the Cape Peninsula, most subpopulations are now locally extinct due to habitat loss to urban expansion, and continues to threaten plants outside protected areas, which are also threatened by inappropriate fire management. |
Population |
Out of 13 surveyed subpopulations, only one has between 100 and 250 individuals, while the majority have only between 10 and 50 individuals. We estimate therefore than most subpopulations have under 100 individuals that with an estimated 50 subpopulations the total population is <5000.
