Habitat and Ecology
It lives in montane and submontane forest and degraded forest. During the breeding season males can be found on wet clay, in rock crevices, and small streams; the females hide under stones. Breeding takes place in streams and springs.
It is a common species.
Although it can tolerate degraded forest, it is likely to be threatened by ongoing forest loss due to smallholder farming activities and subsistence wood extraction.
It occurs in the Bafut-Ngemba Forest Reserve.
