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.
Habitat and Ecology
It is a species of fynbos heathland, grassland, dry thicket forest, savannah and agricultural land. It breeds in dams, ponds, and pools along slow-forming streams, tending to favour permanent water.
It is a common species, though it is apparently declining along the northeastern escarpment of South Africa.
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.
It occurs in many protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats and its presumed large population.
This species was under the generic name Amietophrynus but is now treated under Sclerophrys (Frost 2016). The species name has also changed from rangeri ( a replacement name) to capensis, the original combination under Sclerophrys.
This is an amended assessment created to account for the change in generic name.
