From the IUCN Red List Species Account:


Range Description

This species is almost entirely restricted to the mountain ranges of the Western Cape Province of South Africa, extending north as far as Hoogvertoon in the Cederberg, and from the Cape Peninsula east as far as Witelsbos Forest Reserve in the Tsitsikamma Mountains, in the Eastern Cape Province. It occurs up to 1,670 m asl. Its Extent of Occurrence is probably not much greater than 20,000 km2.

Habitat and Ecology

It inhabits mountain fynbos heath land and it is sometimes found on the margins of forest. It breeds during the winter in shallow, seasonal, well-vegetated marshy areas and seepages in high rainfall areas. The eggs are laid out of water on waterlogged earth. Once they have developed to a certain stage the rains sweep them down to streams where the larvae complete their development.


It is quite a common species.

Population Trend


Major Threats

The main threats are the spread of invasive alien vegetation, afforestation, fires taking place too frequently, and urban development in certain coastal areas. However, most of its range is in protected areas, and it is not believed to be significantly threatened.

Conservation Actions

Most of its range is within protected areas.

Red List Status

Least Concern (LC)


Listed as Least Concern since, although its Extent of Occurrence is probably not much greater than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under serious threat and it has a presumed large population.

Taxonomic Notes

Earlier literature refers to this species as Rana fasciata montana.
