Justification:
At global level, the species is widespread with no known major widespread threats. It is therefore assessed as Least Concern.

In central and western Africa, it is listed as Least Concern due to its wide distribution and because it is unlikely to decline fast enough to qualify for listing in a threatened category.

Although this species has a limited distribution in the southern Africa region, it is unlikely to be declining fast enough to qualify for listing in a threatened or Near Threatened category and, therefore, it is assessed as Least Concern. It is also it is expected to be more widespread than currently known in the southern parts of the region.
History:
