Justification
A. petricola has a restricted range (EOO 3700 km²), but is locally extremely common, occurring in subpopulations numbering thousands of individuals. The habitat, shallow soils in rocky outcrops and slopes, is not threatened.

Description
Bushveld, grows on sandstone slopes and granite outcrops.
Threats
About 52% of the range of A. petricola is transformed, mainly by forestry plantations (estimated using GIS, based on national land cover data). However, the extremely shallow soils in and around rocky outcrops and slopes are unsuitable to plantations and, therefore, the transformation is unlikely to have significantly impacted the population. A. petricola is still extremely common in the Nelspruit area and not considered threatened (Van Wyk and Smith 1996).
