Scientific Name | Barleria media C.B.Clarke |
Higher Classification | Dicotyledons |
Family | ACANTHACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2016/08/24 |
Assessor(s) | N. Hahn & L. von Staden |
Justification | A rare species known from three locations that is potentially threatened by habitat loss and degradation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, North West |
Range | Kalahari region near Kuruman. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kuruman Mountain Bushveld |
Description | Uncertain, possibly rocky slopes or koppies. |
Threats |
| The subpopulation at the type locality is likely to have declined due to habitat loss to asbestos strip mining. One subpopulation near Kuruman is potentially threatened by habitat loss to expanding rural settlements. It is potentially threatened by habitat degradation due to overgrazing across its range. |
Population |
Barleria media is a rare and very poorly known species, which was last collected in 1962. The area where it occurs is extremely under-sampled, and efforts are needed to relocate populations of this species in the wild.
