Assessor(s) | V. Zikishe, A.P. Dold & L. von Staden |
Justification | This species is range-restricted with an extent of occurrence (EOO) of 16 288 km² and an area of occupancy (AOO) of 52 km². It is known from seven locations and is potentially threatened by overgrazing. Given that this threat is currently still potential it qualifies for listing a Near Threatened under criterion D2. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape |
Range | This Eastern Cape endemic is found between Graaff-Reinet and Cradock on the Great Escarpment and extends to the Great Winterberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Upper Karoo Hardeveld, Karoo Escarpment Grassland, Amathole Mistbelt Grassland, Amathole Montane Grassland |
Description | It is recorded only on exposed intrusive dolerite sills. |
Threats |
| This species is potentially threatened by livestock grazing and trampling. |
Population |
It was previously a poorly known species, but extensive field surveys of the mountains around Graaff-Reinet and the Great Winterberg Mountains from 2007 to 2012 encountered a number of previously unrecorded subpopulations. It is now known from seven distinct subpopulations. The population is not suspected to be declining, but it may be impacted if grazing pressure increases.
