Justification
A range-restricted Soutpansberg endemic (EOO 20-240 km², AOO<18 km²), known from two sites, but locally abundant. It declined due to collecting in the past, but this is no longer a serious threat and the population appears to have recovered.
Distribution
Endemism
South African endemic

Range

Habitat and Ecology
Major system
Terrestrial
Major habitats
Grassland
Description
Mistbelt regions on steep, south-facing mountain slopes in extremely thin soils, above 1500 m.
Threats
The number of plants at the type locality declined greatly due to illegal collecting between 1962 and 1969 (Reynolds 1969). However, the extreme Aloe collecting frenzy of the 1960s have subsided and collecting is no longer a serious threat. The subpopulation at the type locality appears to have recovered, because according to Craib (2005) the species is locally common at this site. Most of the subpopulations are on privately owned land and the habitat as well as the sites are fairly inaccessible. A. soutpansbergensis is not in immediate danger of extinction (Craib 2005).
Population
Population trend
Stable
Conservation
Protected in the Soutpansberg Conservatory and Happy Rest Nature Reserve. Most of the habitat is protected in private nature reserves (Craib 2005).
Notes
Not recorded from the Blouberg, to the west of the Soutpansberg, where suitable habitat also occurs. Some publications mention a "robust form" of A. soutpansbergensis known from the Wolkberg further south in Limpopo Province (Van Wyk & Smith 1996). However, this may be a separate taxon and is not included in the current assessment.
