Justification | A range-restricted taxon (EOO 1017 km²), known from six to eight locations and declining due to ongoing habitat loss and degradation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape, Western Cape |
Range | Mountain slopes in the Uniondale and Uitenhage districts. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Langkloof Shale Renosterveld, Uniondale Shale Renosterveld, Kouga Grassy Sandstone Fynbos, Kouga Sandstone Fynbos |
Description | Rocky slopes in renosterveld and lower sandstone slopes. |
Threats |
| The most severe threat to this taxon is ongoing habitat loss and fragmentation due to ongoing agricultural expansion. In addition, remaining fragments also continue to be degraded to overgrazing. |
Population |
This taxon is poorly known and rarely collected, but may also be overlooked. Historical records indicate that it occurs at between six and eight locations, and continuing population decline is inferred from ongoing habitat loss to agricultural expansion at most known locations.
