Mt Wokou

Country: Guinea

Administrative region: Macenta (Prefecture)

Central co-ordinates: 8.52167 N, 9.46306 W

Area: 2km²

Qualifying IPA Criteria

A(i)Site contains one or more globally threatened species, C(iii)Site contains nationally threatened or restricted habitat or vegetation types, AND/OR habitats that have severely declined in extent nationally

IPA assessment rationale

Mt Wokou is the only known global location for the critically endangered species Loudetiopsis baldwinii (CR) and is under threat from quarrying.

Site description

Mt Wokou is a large granite inselberg located on the southern side of Macenta town, near the N1 road in Macenta Prefecture, Guinee Forestière. It is the largest inselberg in the area.

Botanical significance

The inselberg has one point endemic species Loudetiopsis baldwinii, which is Critically Endangered and several threatened species. The inselberg has not been surveyed comprehensively and it is likely that other interesting species will be found with more investigation.

Habitat and geology

The inselberg is a result of a Mesozoic igneous intrusion into the surrounding older Archean metamorphic base rocks. It is part of a band on igneous intrusions, perhaps a sill or dyke which runs northeast-southwest into Sierra Leone.

Conservation issues

There is are granite quarries established on the southwestern and southeastern edge of the inselberg which poses a significant threat to the habitat.
