Listed as Endangered because the extent of occurrence (EOO) of its confirmed range is 1,155 km2 and its area of occupancy (AOO) is 341 km2, representing two threat-defined locations, and there is ongoing decline in the quality and extent of its habitat.
|Previously published Red List assessments:|
|Range Description:||This species is known from two localities 20 km apart in the eastern highlands of Zimbabwe in the Inyanga region: Nyangani Mountain at 2,500 m Asl (formerly Inyangani) and Mtarazi Falls (at 1,500 m Asl). The estimated AOO is 341 km2, although this may be an overestimate, and the EOO is 1,155 km2. It appears that the species may be extinct at the type locality (Channing et al. 2016). Furthermore, it is likely that a record from the Chimanimani Mountains, 100 km to the south, which span the border between Zimbabwe and Mozambique was misidentified and is not in fact Amietia inyangae (D. Broadley pers. comm. November 2015). As such it is considered to occur in only two threat-defined locations.|

|Population:||The species was described in 1966 and was last collected in 1983 (Channing et al. 2016). Repeated visits to the Eastern Highlands of Zimbabwe (including the type locality) at different times of year over the last ten years (the last in June 2016) failed to locate any adults or tadpoles (J. Harvey pers. comm. 2012, Channing et al. 2016). It is sympatric with Amietia delalandii, which is still plentiful in the area (Channing et al. 2016).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It lives in and around rocky, fast-flowing streams in montane grassland. Adults have been found sitting on rock ledges behind waterfalls, or on rocks in the middle of rapids; juveniles frequent more quiet backwaters. The eggs are laid in shallow rocky pools.|
|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 high-altitude habitat of this species was reported as relatively intact in the 2004 assessment. However, despite part of its range overlapping with a National Park, it might be at risk from logging in pine plantations and small-scale logging by local people, overgrazing by livestock, and expanding human settlement, which also occur within its boundaries. These activities may cause erosion and degrade the quality of the streams on which the species depend. In 2010, the presence of chytrid fungus was confirmed in amphibians of the Chimanimani Mountains and may well be present in the Inyanga region (J. Harvey pers. comm. June 2012).|
It occurs in the Rhodes Nyanga National Park of the Inyanga region, which is well managed.
Improved management of the National Park is needed to protect the species' habitat.
Further information is needed on the species' population status, natural history, and threats.
