This species ranges from extreme southeastern Nigeria through central and southern Cameroon to Equatorial Guinea, central Gabon and southwestern Central African Republic to the Democratic Republic of Congo. It occurs below 1,200 m asl. Its eastern distributional limits in the Democratic Republic of Congo are particularly unclear. It is presumed to occur in Congo, and this is included on the map.
Habitat and Ecology
It lives in moist lowland and lower montane forest, and cannot survive in degraded habitats. It is found in mature secondary forest. The animals are usually found on the ground, or in plants up to 20 cm above ground. They breed in forest streams and the males call from slopes and marshy depressions close to streams.
This is the most common species of Cardioglossa in Cameroon.
Due to its large range, and its intolerance of secondary habitats, it is likely that there are declines in some areas due to forest loss.
It presumably occurs in a number of protected areas, and has definitely been recorded from Korup National Park.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution and presumed large population.
