Geographic Range

This species ranges from Sierra Leone, through southern Guinea and Liberia, to southern Côte d’Ivoire and south-western Ghana.
Using the range as a proxy, the extent of occurrence (EOO) is estimated to be 297,627 km2.
Is there any information available regarding the AOO, number of threat-defined locations or the elevation range of this species? EJM

Population

It is rare in Taï National Park (south-western Côte d’Ivoire), but perhaps more common in coastal forest in Côte d’Ivoire; it is locally common in Sierra Leone.

Habitat

This is a lowland rainforest species, and its adaptability to altered habitats is not known. The details of its breeding biology are also unknown, but if it is similar to other members of its genus then it probably breeds in temporary pools.

Red List Rationale

Listed as Near Threatened since although this species is still relatively widely distributed, it depends on areas of reasonably undisturbed forest habitat, and so its Area of Occupancy is probably not much greater than 2,000 km2, and the extent and quality of its habitat is declining, thus making the species close to qualifying for Vulnerable.

According to our records this species may not have been formally reassessed. The current assessment relies on an estimate of the AOO; it would make this a more robust assessment if this could be confirmed with reasoning. To qualify for the VU category, an estimate of the number of threat-defined locations or evidence that the population is severely fragmented (according to the Red List guidelines) is needed. EJM
