In West Africa, the coastal area of Mauretania, Senegal, Gambia, Guinea-Bissau, Guinea and Cabo Verde extends over nearly 3200 km of rocky cliffs and sandy beaches in the north, muddy flats and mangrove forest in the south, as well as a volcanic archipelago. This whole area is mainly characterized in the north by upwellings of deep waters bringing abundant nutrients to the surface of the sea. When exposed to the tropical sun, these fertile waters constitute an ideal environment for the development of plankton, which is a starting-point for the very high marine productivity and, particularly, for fishery resources. In the south, the Guinean coastal area is largely estuarine with vast mangrove forests which capture the nutrients from the drainage basins and represent nurseries and spawning grounds for shallow water fish. Extremely diverse marine fish, birds, tortoises and mammals make use of this coastal environment and make there seasonally transnational migrations in order to restore their reserves.
