National Status |
Status and Criteria | Endangered B1ab(i,ii,iii,iv,v) |
Assessment Date | 2015/06/30 |
Assessor(s) | P. Goldblatt & L. von Staden |
Justification | EOO 911 km², between four and six severely fragmented remaining subpopulations continue to decline due to ongoing habitat degradation and competition from alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Darling to the Cape Peninsula. It historically occurred as far as Hopefield and Tulbagh. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Granite Renosterveld, Peninsula Sandstone Fynbos, Peninsula Shale Fynbos, Cape Flats Sand Fynbos |
Description | Wet, sandy flats and lower slopes. |
Threats |
| A few, scattered subpopulations of this species remains after extensive habitat loss to urban and agricultural expansion. All known subpopulations occur on isolated remnants, where they are threatened due to overgrazing, competition from alien invasive plants, and inappropriate fire management. |
Population |
This species is known from only a few, scattered subpopulations. The largest subpopulation occurs on Rondebosch Common, on the Cape Flats, but most subpopulations on the Cape Peninsula known through historical records are now locally extinct. It is also known from three, possibly four, small isolated fragments around Darling.
