Higher Classification | Dicotyledons |
Family | FABACEAE |
National Status |
Status and Criteria | Vulnerable B1ab(iii,v)+2ab(iii,v) |
Assessment Date | 2018/06/01 |
Assessor(s) | L. von Staden |
Justification | This taxon has a restricted range, with an extent of occurrence (EOO) of 500 km². It is known from seven locations and threatened by competition from spreading alien invasive plants. It is therefore listed as Vulnerable under criterion B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to South Africa, and is found in the mountains between Grabouw, Stellenbosch and Paarl, and also in the mountains south-west of the Breede River Valley near Worcester in the Western Cape. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kogelberg Sandstone Fynbos, Hawequas Sandstone Fynbos, Boland Granite Fynbos |
Description | It occurs on lower sandstone and granite slopes. |
Threats |
| This taxon has lost habitat to timber plantations in Jonkershoek, Wemmershoek and the Berg River Valley at Franschhoek in the past. Timber plantations are however no longer expanding and this threat has ceased. Subpopulations on slopes above plantations are currently threatened by rapidly spreading escaped pine seedlings, which are already outcompeting native species around Franschhoek Pass, Wemmershoek and the Groot Drakenstein Mountains west of Franschhoek. Spreading, unmanaged alien invasive species is also a threat to a subpopulation in Du Toit's Kloof. |
