Assessor(s) | R.C. Turner, P. Goldblatt & T. Patel |
Justification | This species has an extent of occurrence (EOO) of 319 km², and an area of occupancy (AOO) of 56 km². It is known from eight locations. It is potentially threatened by livestock overgrazing and trampling and climate change as it grows in seasonally wet pools. It almost meets the threshold to be listed as Vulnerable under criteria D and is therefore assessed as Near Threatened. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | It is endemic to South Africa, and is restricted to higher elevations in the Kamiesberg of central Namaqualand in Northern Cape. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kamiesberg Mountains Shrubland, Namaqualand Granite Renosterveld |
Description | It occurs on mountain renosterveld or dry montane fynbos, in shallow seasonal pools, or in damp sand or moss overlying flat or concave granite rock shelves. |
Threats |
| This species has lost 8% of its habitat through agricultural activities (calculated using landcover data in GIS). Overgrazing and trampling by livestock may pose a problem to this species. This species grows in seasonally wet pools - climate change could pose a severe threat, especially in drier localities such as the Kamiesberg. |
Population |
It is known from eight locations with a stable population trend.
