Scientific Name: Cardioglossa schioetzi
Species Authority: Amiet, 1981

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Jean-Louis Amiet, Arne Schiøtz
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Endangered because its Extent of Occurrence is probably less than 5,000 km2, its distribution is severely fragmented, and the extent of its forest habitat in the Cameroonian and Nigerian mountains is declining.

Geographic Range [top]

Range Description: This species is endemic to the Oshie-Obudu Ridge in Cameroon and Nigeria. It is found from Acha Tugi on Mount Oshie in Cameroon and from the Obudu Plateau in Nigeria. Its altitudinal range is 1,640-1,800m asl.
Countries occurrence:
Cameroon; Nigeria

Population [top]

Population: There is no information available on its population status, and the species is generally poorly known.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It lives in and around relict patches of montane forest, which are now fragmented, and also in secondary vegetation in which no trees remain. It has been found on steep slopes of scree, boulders and clay, overgrown with a dense cover of high grass and trees. It has also been found around streams, where it presumably breeds.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): It is threatened by habitat loss due to expanding agricultural activities and human settlements, and overgrazing.

Conservation Actions [top]

Conservation Actions: It occurs in the Cross River National Park in Nigeria, but further measures are urgently needed to protect the remaining patches of habitat in its very small range. Additional survey work would be useful to determine the current population status of this species.
