is small (ca. 30 km2), it is common (probably>10 000 individuals) in its restricted area. There are no obvious risks from the current land-use of livestock grazing: plants do not show evidence of damage from foraging or trampling. The remote, rocky high-altitude habitat renders it relatively safe from other detrimental land-use. Already restricted to summit elevations, it is however potentially at risk from global climate change. Any potential wind farm proposals for the Toorberg-Koudeveld-Meelberg would place this species at serious risk. The category VULNERABLE (Vu D2) is thus recommended.
