Justification | An extremely rare habitat specialist, known from two small, isolated subpopulations, and potentially threatened by collecting and disturbance by baboons. |
Distribution |

Provincial distribution | Northern Cape |
Range | Richtersveld. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Central Richtersveld Mountain Shrubland |
Description | Shaded quartzite cliffs. |
Threats |
| Foraging baboons are damaging fruiting heads, and sometimes dislodging individuals from cliff ledges. This should not be a threat, but because the population of A. paradisicola is so small, it is likely to increase this its risk of extinction. Severe degradation of rangelands across the Richtersveld due to overgrazing is causing wild species such as baboons to be increasingly forced to forage in areas inaccessible to livestock, such as this species' habitat, as these are the only places where suitable food sources remain. The species is also targeted for medicinal collection in the Richtersveld, but the extent of the impact is not known. Most plants occur on inaccessible rock ledges where they are unlikely to be reached, but those on lower slopes may be targeted. |
Population |
Known from only two small subpopulations, the largest consisting of around 1000 mature individuals, the second has several hundred mature individuals.
|
Population trend | Stable |
Conservation |
| Protected in the Richtersveld National Park. |
