Justification | Colchicum villosum is a rare and localized habitat specialist, and has a restricted distribution range, with an extent of occurrence (EOO) of 743 km². It has no severe threats and is therefore not suspected to be in danger of extinction. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | This species is endemic to a small area on the western edge of Bushmanland, between Gamoep and Kliprand. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Namaqualand Heuweltjieveld, Namaqualand Blomveld |
Description | It occurs on rock ledges and gravel slopes in granite outcrops in succulent karoo. |
Threats |
| There are no known threats to this species. It occurs in a remote area where human impact on the environment is low. |
Population |
This species is known from only a few collections, representing four subpopulations. It is a localized habitat specialist, and subpopulations are small. It is likely to be more common than records suggest as its distribution range remains botanically relatively poorly explored. As there are no severe threats, the population is not suspected to be declining.
