Listed as Endangered because its extent of occurrence (EOO) is 354 km2, it occurs in two threat-defined locations, and there is continuing decline in the extent and quality of habitat in western Cameroon.

Geographic Range [top]

Range Description:This species was previously only known from the southern slopes of Mount Tchabal Mbabo on the Adamawa Plateau in western Cameroon, between 1,700–2,100 m Asl . However a record has been provided from the Gotel Mountains in the Adamawa Province, near the Cameroon-Nigeria border at 2010 m asl (Gvoždík 2011), suggesting it may occur into Nigeria. It is unlikely to occur on the northern slopes of Mount Tchabal Mbabo, at least not at the altitude of the type locality, because the forest habitat on the northern slopes at this altitude is very different from the gallery forest on the southern slopes. It occurs in two threat-defined locations and its EOO is 354 km2.

Population [top]

Population:There is little information, although it is likely to be common within its small range, since 73 specimens were collected close together suggesting a high concentration of animals. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species lives in montane gallery forest and is associated with streams, in which it presumably breeds by larval development. Individuals have been found under large stones around shallow pools adjacent to a creek. They were observed calling at night during the dry season.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no records of this species being utilized.

Threats [top]

Major Threat(s): The remaining forest habitat on Tchabal Mbabo is now confined to galleries and steep inaccessible slopes, as a result of the clearing of forest for pasture. However, much of the forested habitat that can be easily removed has now been cleared due to conversion to agricultural land and from logging. Fires are also a threat to the forest within this species' range.
