This species is thought to be restricted to the plateau on Inyanga mountain in eastern Zimbabwe. It has been found at 2,400–2,560 m Asl, but probably also occurs at slightly lower elevations. The extent of occurrence (EOO) is 94 km2, the area of occupancy (AOO) is 10 km2, and it occurs in a single threat-defined location.
Habitat and Ecology
The species inhabits montane grassland with exposed bare granite. It hides under stones, in cracks in the granite, and in rodent burrows. It breeds in temporary pools and larvae have been seen moving across wet granite faces.
It is common within its very limited range and was successfully recorded during surveys in 2015 (R. Hopkins pers. comm. November 2015).
The high-altitude habitat of this species has remained relatively intact up until now and there are no ongoing threats to the species. Thanks to the management practices in the National Park, threats listed in the 2004 assessment of this species (wood plantations, overgrazing by livestock, and human settlement) are no longer thought to affect the species. However, chytrid fungus poses a potential future threat to the species as it has been confirmed other regions of the eastern highlands of Zimbabwe (J. Harvey pers. comm. June 2012).
It is known only from the Rhodes Nyanga National Park, which is well managed.
Ongoing management of the National Park will be critical to maintaining the habitat
Further surveys would help to confirm the limits of the species' range.
Red List Status
Listed as Vulnerable under criterion D2 as the species' range is very restricted and infection by chrytrid fungus consists of a potential future threat that could cause rapid declines in its population.
