Threats
Baakens River valley in Port Elizabeth is affected by heavy impact of visitors trampling natural vegetation, resulting in the degradation of this species' habitat. There is also ongoing expansion of suburban residential areas in the Glen Hurd area, which is further reducing the available habitat.
Population

In the Baakens River Valley, a large subpopulation of between 1000 and 2000 plants is restricted to a rocky outcrop of about 1 500 m². Plants grow in an area rich in other succulents. The status of the population in the Addo Elephant National Park is not known.
