The project area is listed as an Important Bird Area (Fishpool & Evans 2001) and holds a high proportion of the threatened and endemic species of the region and a good representation of Guinea-Congolian forest biome species. Many of these species are also present in the community forests of the project zone (Demey 2011). Recent bird surveys (Klop et al 2010, Demey 2011) recorded 294 species in the project zone bringing the total to 327, which is amongst the highest of the Upper Guinean Forests. The birds that occur in the project zone include flagship species such as White-necked Picathartes, Rufous Fishing-Owl, White-breasted Guinea fowl and Gola Malimbe. Besides the high species diversity, several threatened species occur in good numbers. For more information about birds, click here.

The importance of the project zone in the overall butterfly biodiversity of Sierra Leone can hardly be overestimated. Recent surveys have indicated that the project zone holds an extremely high diversity of butterflies, probably well in excess of 600 species or 80% of all the 750 species known from Sierra Leone. A significant proportion of the rarest and most interesting species in Sierra Leone are almost limited to the project zone, the great majority of which are forest-dependent (Safian 2009), two recently encountered butterflies are new to science (Safian 2011). Because of the incomplete IUCN assessment of invertebrates, the conservation status of many of these species is not clear. An overview of noteworthy species is given by Larsen & Belcastro (2008) and Safian (2011). Four recent descriptions of species new to science are based, at least in part, on material collected in the project zone.
