|Scientific Name:||Hyperolius horstockii|
|Species Authority:||(Schlegel, 1837)|
|Red List Category & Criteria:||Least Concern ver 3.1|

|Contributor(s):||Channing, A., Turner, A., de Villiers, A., Harrison, J., Harvey, J., Tarrant, J., Measey, J., Tolley, K., Minter, L., du Preez, L., Burger, M., Cunningham, M., Davies, S. & South African Frog Re-assessment Group (SA-FRoG)|
|Facilitator/Compiler(s):||Morris, E.J. & Measey, J.|
Listed as Least Concern as although it has a relatively restricted extent of occurrence (18,000 km2), its area of occupancy (900 km2) is large. It is not considered to be severely fragmented, and despite some impact on a limited number of subpopulations, it is known to adapt to disturbed environments.
|Range Description:||This is a coastal species occurring at low elevations (<500 m asl) along the southern coast of the Western Cape (including the Cape Peninsula), and east into the western part of the Eastern Cape. Its EOO is 18,000 km2, with an estimated AOO of 900 km2 (5% of EOO).|
Native:South Africa (Eastern Cape Province, Western Cape)

This species is relatively abundant in many wetland areas and can tolerate disturbance. It is not considered to be severely fragmented.
|Habitat and Ecology:||It lives in wetlands in coastal fynbos heathland. It breeds in large and small pans, dams, vleis, and even slow-flowing streams. It needs emergent vegetation, and therefore requires relatively permanent water, though it seems to avoid very deep water.|
|Use and Trade:||
There are no reports of this species being utilized.
|Major Threat(s):||Spreading alien vegetation can lead to drying out of its breeding habitats. It is probably also adversely affected by fires. Several populations have disappeared due to the impacts of agricultural and urban expansion on its native habitat. No evidence exists that collection of Arum Lily flowers affects this species in any way whatsoever.|
|Conservation Actions:||No conservation actions are currently prioritised for this species. It occurs in several protected areas, including Table Mountain National Park and De Hoop Nature Reserve.|
