The wildlife of Guinea is very diverse due to its wide variety of habitats. The southern part of the country lies within the Guinean Forests of West Africa biodiversity hotspot, while the north-east is characterized by dry savanna woodlands. Ecoregions of Guinea are the Western Guinean lowland forests, Guinean montane forests, Guinean forest–savanna mosaic, West Sudanian savanna, and Guinean mangroves.
Populations of large mammals are restricted to uninhabited distant parts of parks and reserves, and those populations are declining. Strongholds of Guinean wildlife are Pinselly Classified Forest, National Park of Upper Niger, Badiar National Park, Mount Nimba Strict Nature Reserve, Ziama Massif, Bossou Hills Reserve, and Diécké Classified Forest.
