From the IUCN Red List Species Account:

 

Range Description

This species is known from Banco National Park, eastern Côte d'Ivoire (Assemian et al. 2006) and a number of sites in south central and southwestern Ghana, adding to a total of five sites (M.-O. Rödel pers. comm. June 2012)Its elevational range varies from 35-170 m asl. Its range, taken as a proxy for extent of occurrence (EOO), is estimated to be 50,740 km2. Its area of occupancy (AOO) based on a 4 km2 cell is estimated to be 32 km2 (J. Penner pers. comm. September 2013).

Habitat and Ecology

It is found in lowland undisturbed and slightly degraded rainforest. It breeds in small rivers. In Banco National Park, Ivory Coast it was recorded in the leaf litter of swampy areas in closed canopy forest, open forest and in natural forest gaps, both in close vicinity to the River Banco and at a larger distance (about 1 km) from the river (Assemian et al. 2006). It might be able to tolerate slight habitat degradation (M.-O. Rödel pers. comm. June 2012).

Population

It is not thought to be abundant (N.G. Kouame pers. comm. June 2012). There is no information on its current population trend (M.-O. Rödel pers. comm. June 2012).

Population Trend

unknown

Major Threats

Current threats include forest degradation and logging. In Banco, logging is due to local people collecting fire wood. Rainforests in southeastern Ivory Coast are under intense logging pressure, leaving them highly fragmented (Rödel et al. 2012). Rainforests in Ghana are better protected but still fragmented, and in the Ateva Reserve there is small-scale gold mining and logging. There are plans to increase the mining to an industrial scale (Rödel et al. 2012, M.-O. Rödel and N.G. Kouame pers. comm. June 2012).

Conservation Actions

It occurs in several protected areas, including Banco National Park, Afao Hills Forest Reserve, Draw River Forest Reserve, Ankasa Conservation Area and Atewa Range (Rödel et al. 2005, 2012). However, additional habitat protection is required. Research is needed on its ecology and population size (M.-O. Rödel pers. comm. June 2012). Population monitoring is required due to the decline in this species' habitat.

Red List Status

Near Threatened (NT)

Rationale

This species is listed as Near Threatened because, although it is still relatively widely distributed (ca 50,740 km2), its area of occupancy is estimated to be 32 km2 and its forest habitat is declining in both extent and quality in eastern Côte d'Ivoire and south Ghana.
