Guinean Forests of West Africa

Last updated

The Guinean forests of West Africa is a biodiversity hotspot designated by Conservation International, which includes the belt of tropical moist broadleaf forests along the coast of West Africa, running from Sierra Leone and Guinea in the west to the Sanaga River of Cameroon in the east. The Dahomey Gap, a region of savanna and dry forest in Togo and Benin, divides the Guinean forests into the Upper Guinean forests and Lower Guinean forests.

The Upper Guinean forests extend from Sierra Leone and Guinea in the west through Liberia, Côte d'Ivoire, and Ghana to Togo in the east. The Lower Guinean forests extend east from Benin through Nigeria and Cameroon. The Lower Guinean forests also extend south past the Sanaga River, the southern boundary of the hotspot, into southern Cameroon, Equatorial Guinea, Gabon, Republic of the Congo, Cabinda, and Democratic Republic of the Congo.

Ecoregions

The World Wide Fund for Nature divides the Upper and Lower Guinean forests into a number of distinct ecoregions:

Upper Guinean forests

Lower Guinean forests

Formerly, this region was largely covered in rain forest, on both well-drained sites and in swamp forests, but little undisturbed primary forest now remains, having been replaced in many areas by savanna and secondary-growth forest.
