Least Concern (LC)
Assessors: IUCN SSC Amphibian Specialist Group
Contributors: James Harrison Leslie Minter
Facilitators: Evie Morris
Reviewers: Simon Stuart

Rationale (Changed due to Same category and criteria)

Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification and its presumed large population.

Distribution

This species is restricted to the southwestern Cape in South Africa, ranging from near Humansdorp in the east along the coastal flats and Cape Fold Mountains to Nieuwoudtville in the west. It occurs from sea level up to 1,500 m asl. There are very few recent records from the eastern part of its range, and there might be genuine gaps in its distribution not reflected in the map.

Population trend

Trend

It has disappeared from certain sites where it used to be common around Cape Town and Stellenbosch, but it is probably more stable and common through most of its range. It is thinly spread, and is rarely encountered in the eastern part of its distribution, probably due to limited habitat, but large-scale emergences have been observed.

Threats

The main threats are continuing coastal development, the impacts of alien plants on its habitat, and wetland drainage for urbanization and agriculture.

Uses and trade

There are no reports of this species being utilized.

Conservation

It occurs in several protected areas.
