Major system
Major habitats
Forest, Fynbos, Grassland, Indian Ocean Coastal Belt, Savanna
This species' habitat is variable. It most often occurs on rocky outcrops, or on exposed ridges and krantzes in mountainous areas, from sea level to 2000 m.
There are no severe threats to this species.

This species is exceptionally common, and the population is not suspected to be declining.

Population trend
Several traditional uses have been identified for this Aloe, of which most conspicuous is its use as living fences around kraals. In the Eastern Cape kraals that have been abandoned as long as 50 years ago are still conspicuous due to the remains of hedges of this species (Glen and Hardy 2000).
