National Status | Status and Criteria | Endangered B1ab(i,ii,iii,iv,v); C2a(i) | Assessment Date | 2022/05/18 | Assessor(s) | P. Goldblatt, J.C. Manning, I. Ebrahim, L. von Staden & D. Raimondo | Justification | This species is rare and localized and has an extent of occurrence (EOO) of 918 km² and area of occupancy (AOO) of 52 km². It is known from four small, isolated subpopulations, the largest consisting of about 200 mature individuals. The population is estimated to number less than 500 mature individuals, and continues to decline due to ongoing habitat loss and degradation. It therefore qualifies as Endangered under criteria B and C. |
Distribution | Endemism | South African endemic | Provincial distribution | Western Cape | Range | This species is endemic to the Western Cape Province, where it stretches from Tulbagh to Wolseley. |
Habitat and Ecology | Major system | Terrestrial | Major habitats | Swartland Granite Renosterveld, Breede Shale Fynbos, Boland Granite Fynbos | Description | Plants occur on shale and granite renosterveld and fynbos on lower slopes. |
Threats | | This species has already lost between 30 and 40% of its habitat to expansion of vineyards and orchards, and habitat loss continues. Some sites are also affected by inappropriate fire management, and spreading, unmanaged alien invasive plants. |
Population | It is known from four small, isolated subpopulations, the largest of which consist of about 200 mature individuals. The population is estimated to number fewer than 500 mature individuals, and continues to decline.
