Assessor(s) | D. Raimondo, N.A. Helme, L. von Staden & T. Patel |
Justification | This locally common species has an extent of occurrence (EOO) of between 1234-3059 km² and an area of occupancy (AOO) of 68-72 km². It is known from between 12-14 locations, and the population is declining due to ongoing habitat loss to crop cultivation. It nearly meets criteria B to be listed as Vulnerable, and is therefore listed as Near Threatened. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | This species is endemic to South Africa, and is distributed in the lower Olifants River Valley between the Nardouws mountains and the foot of the Matsikamma mountains and Kobee Valley in Western Cape and in the Bokkeveld mountains near Lokenberg in Northern Cape. An isolated record from the Farm Driefontein southwest of Calvinia needs confirmation. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Tanqua Escarpment Shrubland, Klawer Sandy Shrubland, Knersvlakte Dolomite Vygieveld, Vanrhynsdorp Gannabosveld, Knersvlakte Shale Vygieveld, Vanrhynsdorp Shale Renosterveld |
Description | It occupies dry, arid stony clay flats and slopes, on seasonally moist sands. |
Threats |
| This species has lost 27% of its habitat (calculated using landcover data in GIS). On the flats south-east of Vanrhynsdorp, the Bokkeveld Escarpment, as well as further south around Klawer, it is threatened by ongoing habitat loss to crop cultivation. It is, however, relatively undisturbed elsewhere within its range (Goldblatt and Manning 2013). |
Population |
The population has a decreasing trend, however, it is known to be locally common. Across its range, subpopulations occur in 12-14 locations. Ranges of between 10-50; 10-50 and 50-100 plants were reported at three subpopulations in 2021 from iNaturalist observations.
