From the IUCN Red List Species Account:


Range Description

This species is endemic to South Africa, Lesotho and Swaziland. It is widely distributed, except in the drier areas, in the Western Cape Province, east through the Eastern Cape Province, to Lesotho and KwaZulu-Natal Province, and northwards through western Swaziland to Mpumalanga and Limpopo Provinces. There are isolated populations in South Africa on the borders with Botswana and Namibia, and it presumably occurs in these two countries, although there have not so far been any records. It is introduced on St. Helena. It occurs from sea level up to 1,800 m asl.

Habitat and Ecology

It inhabits all biomes of South Africa, excluding the arid areas, such as forest, fynbos heath land, thicket, savannah and grassland, as well as modified habitats. It breeds in almost any well vegetated shallow body of water, such as pools, dams, ponds, ditches, and brackish pools along the coast within the spray zone, and shallow seeps. It can also tolerate polluted waters. It lays its eggs out of the water in moist situations, and the tadpoles enter the water to complete their development.


It is a common species.

Population Trend


Major Threats

It is an adaptable species that is not facing any significant threats, except in localized situations. Chytrid fungus was detected in this species in Western Cape, South Africa.

Conservation Actions

There are several protected areas within its range.

Red List Status
