Mt Konossou

Country: Guinea

Administrative region: Guéckédou (Prefecture)

Central co-ordinates: 8.88028 N, 10.36833 W

Area: 16km²

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 Konossou is the only known global location for the endemic monospecific genus Feliciadamia stenocarpa. Its habitat is threatened by uncontrolled burning for agriculture and hunting and needs to be better protected, otherwise this species will become extinct. Granite inselbergs are a threatened habitat in Guinea as they are often quarried.

Site description

Mt Konossou is a small chain of granitic mountains in the Guéckédou prefecture situated between the sub-prefectures of Kassadou and Gbolodou in Guinée Forestière. It is locally called Konsou in the local Lélé dialect which means ‘mountain of rock’. The main peak is at 1350 m, with several smaller peaks between 900m and 1300m over a core area of 16km2, with a buffer zone of 136km2.

Botanical significance

This is only known site for the Guinean endemic Feliciadamia stenocarpa, rediscovered in 2017. This species of Melastomataceae is a monospecific genus and is only known to grow in the moist shaded overhangs in the granite between 900m and 1350m.

Habitat and geology

Granitic outcrop belonging to the Leonean-Liberian massif, from the late Archean period. It forms part of the chain of inselbergs and granite outcrops extending northeast-southwest from Kissidougou prefecture into Sierra Leone, and east in Guinea to Macenta prefecture. The vegetation ranges from grassland, with small marsh areas, to shaded cliffs, and wooded grassland at the base of the mountain, with gallery forest along the base and small pockets of forest at the summit.

Conservation issues

The main threats to this area are from the neighbouring populations at Yogboma, Gbodou, and Songbo. Hunters and farmers set fires for field clearance and hunting. This uncontrolled burning may be a real threat to the population of Feliciadamia stenocarpa, if seed heads are burnt in the dry season. There are also some rice fields that have been made on the plateaus at 600-700m altitude. There are forest guards present in the area, but due to the size of their area for patrol, little protection is provided. Granite inselbergs are a threatened habitat in Guinea, as they are often quarried for building materials. However, this site’s remote location is currently protecting it from quarrying.
