Listed as Least Concern in view of its relatively wide distribution, tolerance of a degree of habitat modification and presumed large population.

Geographic Range [top]

Range Description:This species has been recorded from several localities in the western Cameroon mountains from the Bamenda Highlands north-east to the Adamawa Plateau, with some outlying subpopulations at lower altitudes to the south of this range on Mount Ngorro and the Yoko (Djan) Mountains. It has also been recorded from the Obudu Plateau in eastern Nigeria. It occurs in the submontane zone from 900–2,029 m Asl (M. Hirschfeld pers. comm. July 2016). The distribution is discontinuous, perhaps due to forest clearance in the 17th century.
Countries occurrence:
Cameroon; Nigeria

Population [top]

Population:It is reported to be common within its range. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:This species lives in or near flowing water in lower montane and submontane forest or herbaceous vegetation and gallery forests. At night it can be found in relatively dry areas along forest tracks and in agricultural areas. It can survive in slightly deforested areas, although it always requires canopy cover, in temporary, eutrophic, silted streams that are low in oxygen. Breeding takes place in flowing water, with the males calling from rock cavities or from in the water.
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: This species may be eaten in some of the local villages within its range as other species in the genus are (e.g. A. perreti), although it would not be not consumed at levels that constitute a major threat to the species (M. Hirschfeld pers. comm. July 2016).

Threats [top]

Major Threat(s): Although this species is probably suffering from habitat loss due to urbanization and forest clearing for agriculture and from logging, it appears able to adapt to some non-forest habitats. Local human consumption may be a threat to this species (M. Hirschfeld pers. comm. July 2016).

Conservation Actions [top]

Conservation Actions: This species is not known to occur in any protected areas.
