National Status
Status and Criteria
Vulnerable D2
Assessment Date
L. von Staden
A very rare and highly localized species which has an extent of occurrence (EOO) of less than 10 km², and an area of occupancy (AOO) of 8 km². It is probably locally extinct at one location known through historical records, and remains potentially vulnerable to inappropriate fire management. It is therefore listed as Vulnerable under criterion D.
South African endemic
Provincial distribution
This species occurs in the KwaZulu-Natal Drakensberg Mountains, around Cathedral Peak.

uKhahlamba Basalt Grassland
Plants grow in montane grassland, 2000 m.
The entire distribution range of this species falls within an experimental station where the impacts of timber plantations and grassland fire management on plant communities is studied. The species was collected at the type locality prior to the establishment of experimental plots, and the type locality was assigned to a fire exclusion area. By 2006, the entire catchment was taken over by woody species, which shade out grassland species, and this species is thought to be locally extinct in this valley (Carbutt and Bräuchler 2012). At one confirmed location, in a firebreak, Bracken Fern (Pteridium aquilinum) is invading into the habitat, crowding out native species.

Killickia grandiflora has an extremely localized distribution. In the 1950s, the species was reported to be locally common (Killick 1961). Surveys in 2006 recorded only one small subpopulation of about 40 plants. Searches at the type locality were unsuccessful in relocating the species (Carbutt and Bräuchler 2012). It is not known whether it still occurs at a third locality, this site is burnt regularly (Carbutt and Bräuchler 2012) and thus the subpopulation is likely to persist.
