This species has a small geographic range (EOO within South Africa is 1247 km²), and is known from between five and 10 locations, and continues to decline as a result of decreased recruitment due to livestock trampling and overgrazing. Observations of unexplained adult mortality is pointing to the impact of change-related regional warming, which has been shown to cause long-term declines in a sister species, A. dichotoma. The South African population is continuous with Namibia, but since declines due to climate change-related regional warming are also likely to be occurring in Namibia, the status is not downgraded in accordance with IUCN guidelines for regional assessments.
Not endemic to South Africa
Provincial distribution
Northern Cape
Richtersveld and southern Namibia.
Habitat and Ecology
Major system
Major habitats
Central Richtersveld Mountain Shrubland, Western Gariep Hills Desert, Noms Mountain Desert
Dry, rocky areas, often on hillsides.
Threatened by habitat degradation as a result of trampling and overgrazing by livestock. Reports of unexplained adult mortality near Helshoogte and Helskloof in the Richtersveld are likely related to climate change-related regional warming. Clear climate change-related declines have been found in sister species A. dichotoma. A. ramosissima is expected to respond similarly, however at this stage the rate of decline has not been monitored and is not suspected to be significant enough for the species to qualify for listing under the A criterion.
