Rationale
(Changed due to Same category and criteria)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats and its presumed large population.
Distribution
This species ranges through most of South Africa (excluding the central Karoo region), Swaziland and Lesotho, and almost certainly into extreme southern Namibia. It might also occur in extreme southeastern Botswana, extreme southern Zimbabwe and extreme southern Mozambique, but it has not yet been recorded from any of these countries. It is a low-altitude species, ranging up into the Drakensberg Mountains to over 1,000 m asl.
It is a common species, though it is apparently declining along the northeastern escarpment of South Africa.
Threats
It is generally not threatened. The cause of decline in northeastern South Africa is not clear, but it is possibly being displaced by Bufo gutturalis, which is expanding its range, and with which it is hybridising. Bufo gutturalis probably does better than B. rangeri in agricultural areas. Its decrease could also be the result of climate change.
Uses and trade
There are no reports of this species being utilized.
