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.
Daloa is a city in western Ivory Coast. It is the seat of both the Sassandra-Marahoué District and the Haut-Sassandra Region. It is also the seat of and a sub-prefecture of Daloa Department. Daloa is also a commune. In the 2014 census, the city had a population of 245,360, making it the third-largest city in the country. It lies to the west of Yamoussoukro, the capital of Ivory Coast. Daloa is an important trading centre, particularly for cocoa. The city is served by Daloa Airport and is home to the Roman Catholic Diocese of Daloa, with its cathedral at Cathédrale du Christ-Roi.
Mount Nimba Strict Nature Reserve is a protected area and UNESCO World Heritage Site located in both Guinea and Côte d'Ivoire, extending over a total of area of 175.4 km2, with 125.4 km2 in Guinea, and 50 km2 in Côte d'Ivoire. The reserve covers significant portions of the Nimba Range, a geographically unique area with unusually rich flora and fauna, including exceptional numbers of single-site endemic species, such as Nimbaphrynoides, the Nimba otter shrew, and multiple species of horseshoe bats. Its highest peak is Mount Richard-Molard at 1,752 m (5,750 ft), which is the highest peak of both countries.
The Northern Congolian forest–savanna mosaic is a forest and savanna ecoregion of central Africa. It extends east and west across central Africa, covering parts of Cameroon, Central African Republic, Democratic Republic of the Congo, South Sudan, and Uganda. It is part of the belt of transitional forest-savanna mosaic that lie between Africa's moist equatorial Guineo-Congolian forests and the tropical dry forests, savannas, and grasslands to the north and south.
The wildlife of Ivory Coast consists of the flora and fauna of this nation in West Africa. The country has a long Atlantic coastline on the Gulf of Guinea and a range of habitat types. Once covered in tropical rainforest, much of this habitat has been cleared, the remaining terrain being gallery forests and savanna with scattered groups of trees, resulting in a decrease in biodiversity. As of 2016, 252 species of mammal had been recorded in Ivory Coast, 666 species of bird, 153 species of reptile, 80 species of amphibian, 671 species of fish and 3660 species of vascular plant.
The wildlife of the Democratic Republic of the Congo includes its flora and fauna, comprising a large biodiversity in rainforests, seasonally flooded forests and grasslands.
The wildlife of Ghana is composed of its biodiversity of fungi, flora and fauna.
The wildlife of São Tomé and Príncipe is composed of its flora and fauna. São Tomé and Príncipe are oceanic islands which have always been separate from mainland West Africa and so there is a relatively low diversity of species, restricted to those that have managed to cross the sea to the islands. However the level of endemism is high with many species occurring nowhere else in the world.
The Guinean montane forests are a tropical moist broadleaf forest ecoregion of West Africa.
The southern Congolian forest–savanna mosaic is an ecoregion that covers a large area of the southern Democratic Republic of the Congo and northeastern Angola. Its rich blend of habitats provides key insights into the biogeography of central Africa with the extensive climatic variation that it has been experiencing for the last 10 million years. The human population is not high.
The Nimba Range forms part of the southern extent of the Guinea Highlands, adjacent to the Toura Mountains. The highest peak is Mount Nimba on the border of Liberia, Ivory Coast and Guinea, at 1,752 m (5,748 ft), and at the intersection of the Nimba and Toura Mountains. "Mount Nimba" may refer either to Mount Richard-Molard or to the entire range. Other peaks include Grand Rochers at 1,694 m (5,558 ft), Mont Sempéré at 1,682 m (5,518 ft), Mont Piérré Richaud at 1,670 m (5,480 ft), Mont Tô at 1,675 m (5,495 ft), and Mont LeClerc 1,577 m (5,174 ft), all of them are located in Guinea. Mount Nimba Strict Nature Reserve of Guinea and Ivory Coast covers significant portions of the Nimba Range.
The Northeastern Congolian lowland forests is a tropical moist broadleaf forest ecoregion that spans the Democratic Republic of the Congo and the Central African Republic.
