Justification
AOO <2 000 km², known from less than 10 locations. Most locations are from Lesotho, where livestock overgrazing and trampling is a serious threat to wetlands and a cause of habitat erosion.
Distribution
Endemism
Not endemic to South Africa
Provincial distribution
KwaZulu-Natal
Range
Drakensberg Mountains around Sani Pass, widespread across Lesotho.
Habitat and Ecology
Major system
Freshwater
Major habitats
Drakensberg Afroalpine Heathland
Description
Wet places, in streams and bogs at high altitudes, 2000-3500 m.
Threats
Threatened in Lesotho by habitat degradation due to overgrazing and erosion in places. This species' habitat in South Africa is protected and it is not threatened.
Population

Catabrosa drakensbergense is rare in South Africa, but fairly widespread across Lesotho, with the majority of records from the area around Sani Pass. It is possibly declining in Lesotho, but not in South Africa. It is a localised habitat specialist of high-altitude wetlands and streams.
