Listed as Near Threatened because, although this species is fairly widespread, its range includes few protected areas, there is continuing decline in area, extent and quality of its habitat, and its population is considered to be severely fragmented with more than 50% of subpopulations considered to be non-viable. The species should be carefully monitored as the loss of one or more subpopulations could cause the species to qualify for a threatened category.
|Previously published Red List assessments:|
|Range Description:||This species, which is known only from South Africa, occurs in southern Mpumalanga, and central and eastern KwaZulu-Natal, south to Durban on the coast. The northernmost coastal record is from Hluhluwe. Recently the species has been recorded from Witrivier Town, northern Mpumalanga (L. du Preez pers. comm. August 2016). Based on the currently known distribution of this species, it is likely that it occurs in Swaziland, although there are no records confirming that. It ranges from sea level up to over 1,000 m Asl on the summit of the Lebombo Mountains.|
Native:South Africa (KwaZulu-Natal, Mpumalanga)

Breeding congregations of this species appear to be relatively small and widely dispersed. Due to its secretive nature, it appears very difficult to find. This species is considered to be severely fragmented as no subpopulation has >50% of individuals and >50% of subpopulations are considered non-viable.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It inhabits grassland and savanna. It breeds in seasonal pans, swampy areas, and in pools near rivers. It nests in burrows in wet soil close to temporary water, and tadpoles move to water to develop.|
|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):||The bulk of the known range is along the central KwaZulu-Natal coast, where it is highly fragmented and pressured. The main threats to this species include: habitat loss due to afforestation, sugar cane cultivation, urbanization and invasive alien plants lowering the water table.|
This species occurs in Hluhluwe-Imfolozi Game Reserve, and possibly the White River Nature Reserve. The coastal subpopulations occur in some protected areas, such as Umlalazi Nature Reserve, but the areas are not substantial and are heavily pressured in surrounding catchment (J. Harvey pers. comm. August 2016). It might occur in Amatikulu Nature Reserve (small and isolated) and only just overlaps with iSimangaliso Wetland Park in the south. The inland subpopulations are poorly known, but likely do not occur in protected areas. Habitat protection in these areas is moderate, but not enough area is protected (J. Harvey pers. comm. August 2016).
Improved habitat protection is required at sites where this species is known to occur.
Studies on its population size, distribution and trends, ability to disperse, life history and ecology (including terrestrial habitat requirements), and threats are needed.
