From the IUCN Red List Species Account:


Range Description

This species is restricted to south-eastern South Africa, where it ranges from Dwesa Nature Reserve in the Eastern Cape Province east to southern and central KwaZulu-Natal Province. Its Extent of Ocurrence (EOO) has been estimated as 15,000 km

Habitat and Ecology

It lives in coastal forests and gallery forests, where it is usually found along streams, and does not survive in open areas. It breeds in streams, hanging its eggs above water on branches, and sometimes on rock faces. The larvae fall into the water where they develop.



Population Trend


Major Threats

Much of the forest habitat of this species has been lost to sugar cane cultivation and other agriculture, woodcutting, afforestation and urbanization. It is also threatened by pollution and siltation of streams.

Conservation Actions

A priority for conservation research is to estimate the population size of adults in subpopulations, as well as determining the cause of direct threats. Obtaining a memorandum of understanding with land owners is also of high priority. It occurs in several protected areas, including Umtamvuna Nature Reserve and Oribi Gorge Nature Reserve. However, additional habitat and waterway protection is required.
