Justification | Aloe petricola is a range-restricted species, with an extent of occurrence (EOO) of 3681 km². It is locally very common, and is not suspected to be in danger of extinction. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Mpumalanga |
Range | This species endemic to a small area on the boundary between the Mpumalanga Lowveld and Escarpment, from Sabie to Barberton, westwards to Schoemanskloof and eastwards to Krokodilpoort and Pretoriuskop in the Kruger National Park. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Legogote Sour Bushveld, Granite Lowveld, Pretoriuskop Sour Bushveld, Northern Escarpment Quartzite Sourveld |
Description | It prefers shallow soil pockets on sandstone and granite outcrops in bushveld. |
Threats |
| About 58% of this species' range is irreversibly modified, predominantly due to urban expansion around Nelspruit and White River, and expansion of fruit orchards and timber plantations. However, shallow rocky soils are generally unsuited to cultivation, and it is unlikely to have been severely impacted by habitat loss. Some subpopulations on isolated ridges are potentially threatened by competition from alien invasive plants.
In spite of some habitat loss, Aloe petricola is still common and not considered threatened (Van Wyk and Smith 2014). |
Population |
Aloe petricola is a very common species, and persists in a large subpopulations even on small bushveld remnants in and around Nelspruit. Localized declines due to habitat loss is likely, but it is not suspected to have a significant impact on the population.
