Geographic Range [top]

Range Description:This species occurs in extreme eastern Nigeria and western Cameroon, below 800 m Asl. Tadpoles have been found in rivers up to 893 m Asl (Mapouyat et al. 2014). Two subspecies are known: the nominate form occurs in the westernmost part of the range (including Nigeria); L. o. orientalis occurs in the east. The ranges of the two subspecies are probably separated around Mount Kupe.

Population [top]

Population:This is a common species. It was found to persist in the Obudu Plateau in Nigeria in a 2002 survey, despite severe habitat degradation within the area, although it was restricted to undisturbed forest fragments (Lea et al. 2005). 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:Unknown

Habitat and Ecology [top]

Habitat and Ecology:This species lives in lowland forest, requiring forest with a continuous canopy, and is not found in degraded forest. Adults tend always be found close to streams (M. Hirschfeld pers. comm. July 2016). Tadpoles have been found in fast-flowing streams, but prefer the slower-moving, stagnant parts of the stream (Mapouyat et al. 2014). It breeds in slow-flowing streams and tiny watercourses in the forest. The males call from holes and cracks in rocks.
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: It is possible that this species is consumed, although it has not been confirmed (M. Hirschfeld pers. comm. July 2016). Tadpoles could be indiscriminately caught for subsistence (M.-O. Rödel pers. comm. July 2016)

Threats [top]

Major Threat(s): It is presumably threatened by the loss of its lowland forest habitat (for agriculture).

Conservation Actions [top]

Conservation Actions: Conservation Actions
This species occurs in Ebo Forest Reserve, which is one of the better protected areas in Cameroon (M. Hirschfeld pers. comm. July 2016). It has also been confirmed in Korup National Park by genetic verification of tadpoles (M.-O. Rödel and M. Hirschfeld pers. comm. July 2016).
