Justification
AOO < 20 km², the habitat of this species has been severely fragmented and degraded by forestry plantations and although not currently declining this species is potentially threatened by alien plants that typically invade fragments between plantations.
Distribution
Endemism
Not endemic to South Africa
Provincial distribution
Mpumalanga
Range
Barberton to Piggs Peak.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Barberton Montane Grassland
Description
Barberton montane grassland, quartzitic soils. Restricted to rocky outcrops, which may be because these areas are fire refugia. 1525m.
Threats
The habitat of this species has been severely fragmented and degraded by forestry plantations. Too frequent fires in fire break areas could negatively affect populations not sufficiently protected by rocky outcrops (Edwards 2006). On the other hand, rocky refugia that are safe from fires also provide a safe haven for escaped pine seedlings and other exotic species associated with the disturbance caused by pine plantations, which become established in these areas and quickly transforms the open grassland habitat to dense thickets.
