<P> The tropical environment is rich in terms of bio-diversity . Tropical African forest is 18 per cent of the world total and covers over 3.6 million square kilometers of land in West , East and Central Africa . This total area can be subdivided to 2.69 million square kilometers ( 74 % ) in Central Africa , 680,000 square kilometers ( 19 % ) in West Africa , and 250,000 square kilometers ( 7 % ) in East Africa . In West Africa , a chain of rain forests up to 350 km long extends from the eastern border of Sierra Leone all the way to Ghana . In Ghana the forest zone gradually dispels near the Volta river , following a 300 km stretch of Dahomey savanna gap . The rain forest of West Africa continues from east of Benin through southern Nigeria and officially ends at the border of Cameroon along the Sanaga river . </P>
