From the IUCN Red List Species Account:

 

Range Description

This species ranges from eastern and northern South Africa, north to Angola, southern Democratic Republic of Congo, Rwanda, Uganda and Kenya, with an apparently isolated population south of Lake Tana, at 1,900 m asl in Ethiopia. It has not been recorded from Burundi, but it is likely to occur in this country and it is included in the species' distribution on the map. Isolated records in Kenya from Katera south of Mount Kenya, and from Nyahururu north of the Aberdare Mountains require confirmation. It occurs mostly in cooler regions, and is generally found above 1,200 m asl in the tropical parts of its range.

Habitat and Ecology

It is a species of moist grassland, savannah and forest, often at higher altitudes. It is an adaptable species that can survive in altered habitats. The Ethiopian locality is in an area of montane grassland and lakeshore habitats. The eggs are laid in shallow grassy, temporary pools.

Population

It is generally common where it occurs. Its status in Ethiopia is unclear, since there have been no records since 1902.

Population Trend

unknown

Major Threats

It is an adaptable species that is not facing any significant threats, except in localized situations.

Conservation Actions

It occurs in several protected areas.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern in view of its very wide distribution, its tolerance of a broad range of habitats and its presumed large population.
