Not endemic to South Africa
Provincial distribution
Gauteng, Limpopo, Mpumalanga
Range
In South Africa this species is known from scattered subpopulations in high altitude grasslands of Limpopo Province, Gauteng and Mpumalanga. It also occurs along the Lebombo Mountains in eSwatini and in the Makoni and Mutare districts in north-eastern Zimbabwe.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Grassland, Savanna
Description
It occurs in exposed places on rocky outcrops and ridges in grassland and open woodland in South Africa and eSwatini. In Zimbabwe it occurs in high rainfall Brachystegia woodland.
Threats
Urban expansion around Pretoria has led to localized declines of A. pretoriensis. However, this area represents only a small proportion of its range. Elsewhere A. pretoriensis is not threatened (Van Wyk and Smith 2014).
Population

This species is now rare in Gauteng due to habitat loss to urban expansion, but elsewhere in its range it is still common and not threatened (Van Wyk and Smith 2014).


Population trend
Stable
Notes
The subpopulations in Zimbabwe are isolated from those in South Africa and Swaziland and show some morphological variation (Kativu 2001).
