Ecology

Habitat and Ecology

Life History

Reproduction

Channing (1988) found that the species breeds in pans, vleis and dams, as well as small watercourses in flat, sandy areas. This species breeds in winter in the winter-rainfall region, and in summer throughout the rest of its range (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Metamorphosis

The tadpoles are benthic and reach 44 mm in length. Metamorphosis takes place within 25–35 days (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Conservation

IUCN Red List Category and Justification of Conservation Status

The IUCN Redlist categorizes this as Least Concern in view of its relatively wide distribution, its tolerance of a broad range of habitats, its presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
