This species has declined in certain parts of its range. The overall population decline is estimated to be <30% over the past 60 years based on repeat photographs and visits to subpopulations. It could be listed as Vulnerable if overall population numbers drop below 10,000 (C1) or if the extent of decline increases from the current level up to 30% or higher.

Habitat and Ecology [top]

Habitat and Ecology:This species occurs on cliffs and steep, hot and dry slopes in scarp forests. Plants grow on cool south-facing cliff faces, in forest or are exposed. E. natalensis occurs close to the coast in certain areas, but more commonly further inland.
Generation Length (years):70

Threats [top]

Major Threat(s): Some subpopulations have been impacted by collecting and bark harvesting for medicinal purposes. For example, the plants at the type locality at Monteseel have been debarked resulting in mortality.
