Scientific Name | Psoralea peratica C.H.Stirt. |
Higher Classification | Dicotyledons |
Family | FABACEAE |
Common Names | Piketberg Fountain-tree (e) |
National Status |
Status and Criteria | Endangered B1ab(ii,iii,iv,v) |
Assessment Date | 2008/02/04 |
Assessor(s) | N.A. Helme & D. Raimondo |
Justification | EOO 490 km², known from less than five locations. Some subpopulations on upper slopes are declining due to alien plant invasions and prolonged droughts - farmers report a reduction in rainfall of as much as 50% in the last 40 years. Subpopulations at lower altitudes are declining due to habitat loss to crop cultivation and overgrazing by livestock. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Piketberg Mountains. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Piketberg Sandstone Fynbos |
Description | Mainly along sandy seepages. |
Threats |
| Subpopulations on lower slopes are declining due to ongoing habitat loss and degradation due to crop cultivation, water extraction and overgrazing. Subpopulations on upper slopes are relatively safe, apart from alien invasive plants becoming dense in some parts of the habitat and a long-term reduction in water supply as a result of a significant drying up of this area (rainfall has dropped 50% in 40 years according to farmers). |
