From the IUCN Red List Species Account:
This species occurs only in south-western South Africa, where it is restricted to the mountains south-west of the Breede River, including the Cape Peninsula (an Extent of Occurrence of 6,526 km
Habitat and Ecology
It is a species of mountain fynbos heathland, and does not survive in altered habitats. Adults congregate to breed in temporary pools, where they lay around 100 eggs in long strings of amber jelly.
It is locally common at breeding sites, and large breeding aggregations can sometimes be found. However, it is absent from some apparently suitable sites and can no longer be found at some historically recorded sites on the Cape peninsula.
The main threat to this species is the loss of its fynbos habitat, mainly because of the spread of alien vegetation and frequent burning. No explanation or threat has been deduced for historical populations now missing from the Cape Peninsula.
Taxonomy, understanding ecology, threats and population size and trends are all high priority areas for research in conserving this species. Known sites need active management to reduce influence by alien vegetation. Much of the range of this species is within protected areas.
A recent phylogeny of this genus suggests that there may be more than two species, and that Capensibufo rosei on the Cape peninsula may be substantially different from subpopulations from other sites (Tolley et al. in press). Resolving the taxonomy of the genus is a conservation priority for this taxon.
