Family | HYACINTHACEAE |
National Status |

Assessment Date | 2016/11/16 |
Assessor(s) | L. von Staden |
Justification | Ornithogalum corticatum is a range-restricted, but locally abundant species that is not threatened. It has an extent of occurrence (EOO) of 1516 km² and is listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | This species is endemic to South Africa where it is found in the Roggeveld Escarpment. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Roggeveld Karoo, Central Mountain Shale Renosterveld, Roggeveld Shale Renosterveld |
Description | It grows in heavy clay soils derived from dolerite. |
Threats |
| The Roggeveld is severely overgrazed, which has led to the near extinction of some endemics. Many Ornithogalum species of the subgenus Aspasia are however poisonous to stock, and thrive under mild disturbance (Manning et al. 2007), which means that grazing has probably favoured this species and may explain why it is so abundant. |
Population |
Ornithogalum corticatum is locally extremely common, with dense colonies of thousands of plants covering large areas of the Roggeveld Escarpment.
|
Population trend | Stable |
