Justification
A localized habitat specialist (EOO and AOO <10 km²) that is potentially threatened by competition from alien invasive plants.
Distribution
Endemism
South African endemic
Provincial distribution
Limpopo
Range
Wolkberg Mountains around Haenertsburg.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Woodbush Granite Grassland, Mamabolo Mountain Bushveld
Description
Shallow soil pockets in rocky outcrops in grassland and open woodland, 1500-1870 m.
Threats
This localized habitat specialist is near-endemic to Woodbush Granite Grassland, a Critically Endangered ecosystem of which less than 30% remains intact, after most of the grasslands have been converted to timber plantations. It is unlikely that habitat loss to plantations have had a severe impact on the population of this species, as the shallow soil pockets in rock outcrops in which it grows is unsuitable to planting of timber trees. It is however potentially threatened by habitat degradation and competition from escaped pine seedlings and other alien invasive plants associated with disturbed areas around and among plantations. These invasive species establish most readily on rocky outcrops where they are sheltered from grassland fires, and can shade out sun-dependent species if not cleared and managed.
