From the IUCN Red List Species Account:

 

Range Description

This species ranges from northern Sierra Leone, through southern Guinea and Liberia to south-western Côte d'Ivoire. It occurs from low altitudes to more than 1,000m asl. Records from eastern Ghana and Togo refer to Conraua derooi. A record from eastern Côte d'Ivoire refers to a juvenile Hoplobatrachus occipitalis.

Habitat and Ecology

It lives in or near fast-flowing permanent streams in rainforest in hilly country. It is forest-dependent, and is not found in open areas. It breeds in streams and the tadpoles are usually found in the slow-flowing or nearly stagnant sections of streams.

Population

It is extremely localized, but abundant wherever it occurs.

Population Trend

decreasing

Major Threats

It is adversely affected by the loss of forest habitat for agriculture, logging, and human settlements. In certain places its habitat is also being lost due to mining, for instance at Simandou in the Pic de Fon Classified Forest in Guinea, and Mount Nimba in Guinea and Liberia. Mining is probably also leading to the pollution of breeding streams.

Conservation Actions

It occurs in several protected areas, including Pic de Fon Classified Forest (Guinea), Haute Dodo Classified Forest and Mont Sangbe National Park (Côte d'Ivoire), and the Mount Nimba World Heritage Site (Liberia and Guinea).

Red List Status

Vulnerable (VU)

Rationale

Listed as Vulnerable because it is dependent on streams rainforest, and so its Area of Occupancy is probably less than 2,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in West Africa.

Taxonomic Notes

Conraua alleni is a species complex (M.-O. Rödel pers. comm.).
