Justification | A rare, range-restricted habitat specialist known from nine subpopulations of about 20-30 mature individuals within an area of about 230 km². |
Distribution |
Endemism | South African endemic |
Provincial distribution | Limpopo |
Range | Bewaarkloof in the Strydpoort Mountains to Lekgalameetse, southern Wolkberg Mountains. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Poung Dolomite Mountain Bushveld, Wolkberg Dolomite Grassland |
Description | Grassland or low, open woodland, restricted to rocky dolomite slopes, 1360-1950 m. |
Threats |
| At the time of the publication of this species (1992) about half of the known subpopulations of this species were threatened by habitat degradation due to overgrazing by cattle on the Strydpoort Mountains (Balkwill et al. 1992, MJ Balkwill pers. comm.) Plans were in place to convert the whole area into a chain of provincial and private nature reserves linking Bewaarkloof to the Wolkberg Wilderness area. There is however at present very little conservation management, and the area is still utilized for cattle grazing and firewood collecting (Anonymous 2010). |
Population |
Nine subpopulations are known, scattered across mountainous areas. There are 20-30 plants in each subpopulation (MJ Balkwill pers. comm.).
