Listed as Vulnerable because its Area of Occupancy is estimated to be 510 km2, its distribution is severely fragmented, and there is continuing decline in its Area of Occupancy and the extent and quality of its habitat. The estimate of the Area of Occupancy provided is conservative in nature; if additional surveys suggest it is more circumscribed then a higher threat category should be considered.
|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 (Extent of Occurrence of 51,000 km2 and Area of Occupancy conservatively estimated to be 1%). The northernmost coastal record is from Hluhluwe. It ranges from sea level up to over 1,000 m on the summit of the Lebombo Mountains. It has not been recorded from Swaziland, but it presumably occurs in this country.|
Native:South Africa (KwaZulu-Natal, Mpumalanga)
|Estimated area of occupancy (AOO) - km2:||510|
|Continuing decline in area of occupancy (AOO):||Yes|
|Estimated extent of occurrence (EOO) - km2:||51000|
|Continuing decline in extent of occurrence (EOO):||No|
|Upper elevation limit (metres):||1000|

Breeding congregations of this species appear to be relatively small and widely dispersed. 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:||Unknown|
|Habitat and Ecology:||It inhabits grassland and savannah. It breeds in seasonal pans, swampy areas, and in pools near rivers. It nests in burrows in wet soil by temporary water, and tadpoles move to water to develop.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||
There are no reports of this species being utilized.
|Major Threat(s):||The main threats include: habitat loss due to afforestation, sugar cane cultivation, and urbanization and invasive alien plants lowering the water table.|
|Conservation Actions:||The highest priority for conservation research of this species is to assess its ability to disperse. Understanding the impact of perceived threats and population size and trends is also required. This species occurs in the iSimangaliso Wetlands Park, the Hluhluwe-Imfolozi Game Reserve, and other protected areas.|
