Taxonomic notes: Conraua alleni is a species complex (M.-O. Rödel pers. comm.).
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.
Using the range as a proxy, the extent of occurrence (EOO) is estimated to be 177,816 km2.
As this represents a species complex, are there any further specifications or new information to add? JAL
Can anyone provide a number of threat-defined locations for this species? EJM
The species is extremely localized, but abundant wherever it occurs. However, it is believed to be in decline. It was most recently found in 2011 (Kouamé pers. comm. May 2012).
Can the 2011 finding be elaborated on? JAL
Is the species believed to be in decline because of direct observation or because of the decline in habitat? EJM
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.
It habitat is in decline due to loss of forest caused by small-holder farming, logging, growing human settlements and, in some places, mining.
It is adversely affected by the loss of forest habitat caused by small-holder farming, logging, and growing 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 streams used for breeding.
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). However, no species-specific conservation actions are in place. More information is needed on this species' taxonomy, distribution, population status, natural history and threats.
Listed as Vulnerable because it is dependent on rainforest streams, so its Area of Occupancy is probably less than 2,000 km2. Also, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat.
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
