Justification:
Ncandu Nature Reserve is protected by KZN Wildlife, but the forests are severely threatened by runaway fires, and these have burnt through the forest on a regular basis in recent years. Those forests at Normandien are on private land, but these are not easily accessible, and fires are probably the major threat. No details are available about the Van Reenen locality, but this may be threatened since this area has undergone transformation through agriculture and alien invasive plants may also be a problem. It is probable that this species occurs more widely than the three localities listed here, since there are other similar habitats north of Van Reenen.

Geographic Range
[top]
| Range Description: |
South Africa: KwaZulu-Natal. Northern part of the Drakensberg mountain range, with localities at Van Reenen, Normandien and Ncandu Nature Reserve. Uncertain, but even if additional localities are found, the maximum area of occurrence is certain to be less than 5,000 km², and the area of occurrence less than 500 km². The forests have a naturally patchy distribution, but the grassland habitat between them is still relatively undisturbed in most areas. |
