Assessment Date | 2014/08/04 |
Assessor(s) | D.A. Snijman, L. von Staden & D. Raimondo |
Justification | EOO 126 km², plants at five known locations are declining due ongoing habitat loss to urban expansion, mining and habitat degradation due to overgrazing. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Vredenburg to Langebaan. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Langebaan Dune Strandveld, Saldanha Limestone Strandveld, Saldanha Granite Strandveld |
Description | Moist patches at the base of granite domes. |
Threats |
| Plants at three locations on the urban edge of Langebaan and Paternoster are threatened by ongoing habitat loss due to urban expansion. A fourth location is threatened by habitat loss due to limestone mining (the site is owned by a cement manufacturer) as well as habitat degradation due to overgrazing. One subpopulation occurs within a protected area and is not threatened. |
Population |
A subpopulation within the West Coast National Park consists of at least 5000 mature individuals (N.A. Helme pers. obs.). Other subpopulations are smaller, consisting of between 500 and 1000 mature individuals. It continues to decline due to ongoing habitat loss and degradation.
