Listed as Near Threatened because, although it has an extent of occurrence (EOO) of 9,488 km2 and a continuing decline in area of occupancy (AOO) and the extent and quality of its habitat, it is relatively common, its population is not considered to be severely fragmented and it occurs at more than 10 locations.
|Previously published Red List assessments:|
|Range Description:||This species is endemic to the southwestern Western Cape Province of South Africa, where it ranges from the central Cape Peninsula in the south, to west of Citrusdal in the north. There is a distribution gap in the Swartland. It ranges from 10 to 600 m Asl. It occurs in more than 10 threat-defined locations and its EOO is 9,488 km2.|
Native:South Africa (Western Cape)

|Population:||It can be relatively common in parts of its range. Its population is not considered to be severely fragmented (as less than half of the individuals can be found in isolated patches).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||It is a burrowing frog of renosterveld fynbos heathland. It also occurs in disturbed habitats, such as pine plantations and gardens, and there is ongoing decline in its habitat over much of its range. It breeds by development occurring directly in subterranean nests with up to 22 froglets recorded for this species (Minter et al. 2004), and is not associated with water-bodies.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||
There are no records of this species being utilized.
|Major Threat(s):||Although it is somewhat adaptable, its habitat has been severely reduced and fragmented by agricultural expansion in much of its range and urban development in parts of its range. It is possibly impacted by the use of pesticides, and herbicides, and it does not occur in agricultural land that is ploughed. This might account for the apparent absence of the species from most renosterveld fragments in the Swartland, north of Cape Town, but more systematic surveys are required. In garden areas Hadeda ibis (Bostrychia hagedash) were seen preying on individuals of this species.|
No conservation actions are currently prioritised for this species. It occurs in several protected areas, including Cape Peninsula National Park, Helderberg Nature Reserve, and Paarl Mountain Nature Reserve. There is no area-based plan specific to this species, but populations in protected areas benefit from the protected area management plan concerned.
Studies on its population size, distribution and trends, life history and ecology, and threats are needed.
