Justification
Aloe dabenorisana is a rare, range-restricted species known from two sites within an extent of occurrence (EOO) of 31 km². Its inaccessible cliff face habitat in an extremely remote area makes it unlikely to be threatened.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape
Range
Aloe dabenorisana is endemic to the Dabenoris Mountains in the Bushmanland region of north-western South Africa.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Bushmanland Inselberg Shrubland, Eastern Gariep Rocky Desert
Description
It occurs crevices of quartz rock on vertical, south-west-facing upper slopes, 900-1000 m.
Threats
Illegal collection is a potential threat according to Van Wyk and Smith (1996). However, the vertical cliff faces where this species grows is remote and inaccessible and therefore it is unlikely to be a serious threat.
Population

Plants are locally scattered and not very common, except on the Pellaberg. This species was last recorded in the 1980s, and field surveys are needed to determine the current status of the population.
