Higher Classification | Dicotyledons |
Family | FABACEAE |
Synonyms | Acacia sekhukhuniensis P.J.H.Hurter |
Common Names | Sekhukhune Thorn (e) |
National Status |
Status and Criteria | Critically Endangered B1ab(ii,iii) |
Assessment Date | 2007/10/08 |
Assessor(s) | P.A. Manyama |
Justification | EOO <10 km², and one known location. At least 60% of the surrounding habitat is already transformed and there is ongoing habitat loss as a result of mining, overgrazing, informal settlement expansion, and subsistence farming. It is also potentially threatened by harvesting for firewood. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Limpopo |
Range | North-eastern boundary of Sekhukhuneland. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Ohrigstad Mountain Bushveld |
Description | Open woodlands and wooded grassland on quartzite ridges. |
Threats |
| This species is only known from the type locality and much of the vegetation in the area has been impacted on negatively by human activities. An estimated 60% has been transformed by urban sprawl and subsistence farming lots, with overgrazing by domestic livestock prevalent throughout. This species is considered threatened mainly due to its extremely small Extent of Occurrence and the fact that much of Sekhukhuneland is under considerable threat from urban sprawl, heavy grazing pressure and extensive, and destructive mining activities (Hurter 2004). It is also potentially threatened by harvesting for firewood and building materials (P. Manyama, pers. obs. 2006). |
