The Guinean forest-savanna mosaic is an ecoregion of West Africa, a band of interlaced forest, savanna, and grassland running east to west and dividing the tropical moist forests near the coast from the West Sudanian savanna of the interior.

Setting

The Guinean forest-savanna mosaic covers an area of 673,600 square kilometers (260,100 sq mi), extending from western Senegal to eastern Nigeria, and including portions of Gambia, Guinea Bissau, Guinea, Sierra Leone, Côte d'Ivoire, Ghana, Togo, and Benin. The Cameroon Highlands of eastern Nigeria and Cameroon separate the Guinean forest-savanna mosaic from the Northern Congolian forest-savanna mosaic, which lies to the east. The Dahomey Gap is a region of Togo and Benin where the forest-savanna mosaic extends to the coast, and separates the Upper Guinean forests of Guinea, Sierra Leone, Liberia, Côte d'Ivoire, and Ghana from the Lower Guinean forests of Nigeria and Cameroon.

Flora

This region is mainly grassland crossed with trees growing alongside streams and on hillsides, with the constantly occurring fires keeping back the growth of trees in open country. Lophira lanceolata is a tree that is more resistant to fire than many others.

Fauna

The mixture of forest and grassland provide habitat for a range of species from large mammals such as African leopard, forest elephants, hippopotamus and antelopes such as the red-flanked duiker to the common tortoise as well as more localised species including patas monkeys and Ghana worm lizards ( Amphisbaenia ).

The wetlands in the region are rich in birdlife, including iris glossy starling and black crowned crane.

Human settlement

The ecoregion covers large areas of many West African nations including:

Protected areas

A 2017 assessment found that 107,116 km², or 16%, of the ecoregion is in protected areas. [2] Protected areas include Upper Niger National Park in Guinea, Dulombi-Boe National Park in Guinea-Bissau, Outamba-Kilimi National Park in Sierra Leone, Mont Sangbé National Park in Ivory Coast, Bui National Park and Digya National Park in Ghana, and Old Oyo National Park and Gashaka-Gumti National Park in Nigeria.

Foreign relations of the African Union

The individual member states of the African Union (AU) coordinate foreign policy through this agency, in addition to conducting their own international relations on a state-by-state basis. The AU represents the interests of African peoples at large in intergovernmental organizations (IGO's); for instance, it is a permanent observer at the United Nations' General Assembly.

Western Guinean lowland forests

The Western Guinean lowland forests ecoregion is a tropical moist broadleaf forest ecoregion of West Africa. It is centered on Liberia, with portions in surrounding countries. It is the westernmost tropical rainforest in Africa, and has high levels of species endemism, with over 200 species of endemic plants.

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 is a tropical seasonal forest region of West Africa. The Upper Guinean forests extend from Guinea and Sierra Leone in the west through Liberia, Côte d'Ivoire and Ghana to Togo in the east, and a few hundred kilometers inland from the Atlantic coast. A few enclaves of montane forest lie further inland in the mountains of central Guinea and central Togo and Benin.

The Lower Guinean forests is region of coastal tropical moist broadleaf forest in West Africa, extending along the eastern coast of the Gulf of Guinea from eastern Benin through Nigeria and Cameroon.
