This reference study on the biological diversity of the forest areas of Dogo-Kétou, the three rivers, the three rivers, Sota, Goungoun, Ouémé-Supérieur and N'Dali, commissioned by the Programme de Gestion des Forêts et Terroirs Riverains (PGFTR), aims to enable it to have recent data on their condition in order to provide it with recent data on their condition in order to develop strategies to be implemented in order to promote management socially, technically and economically sustainable of these forests and coastal areas by village communities within a strengthened institutional framework. It presents the biodiversity situation in all of these classified forests and the proposals for the sustainable conservation of their genetic potential. The classified forests of Dogo-Kétou, Ouémé Supérior-N'Dali, the three rivers, Sota and Goungoun, are marked by a strong human influence and human occupations. Forest cover is largely degraded and wildlife is threatened. These forests show signs of a lack of sustainable and effective management of the biological resources they abound in. Significant areas occupied by local populations are transformed into agricultural and residential areas; important forest strata are deforested (the loss of forest cover varies between 50 and 90%); poachers decimate wildlife without being disturbed. This has increased the number of endangered species and has significantly reduced the abundance of species. But within these forest areas, we notice a significant specific and genetic diversity, with a large extent favorable to animal movements, a rich hydrography and rare species. For this purpose, the implementation of good forest governance is essential. First, it will be a question of defining a new forest regime by including each forest area in one of the IUCN categories and of proceeding with forest certification in order to open up to the international carbon credit market for forestry, conservation and the fight against deforestation. Second, to preserve the existing habitat in which wildlife lives and evolves by developing strategies and actions to cancel out or at least slow down the forces that contribute to the degradation of wildlife habitats. The main elements that need to be regulated in these classified forests include slash-and-burn agriculture, transhumance, logging, charring, and the fight against uncontrolled wildfires. In order to better conserve biodiversity, sustainable management of these forests should be carried out. To do this, for each classified forest, a zoning plan comprising two important areas (one of integral protection and the other of agrosystems), in accordance with the basic principles of the IUCN categories, must be adopted. It is important to make these demarcations in agreement with the local populations. The mechanism of collaboration with local residents in order to stop harmful anthropogenic actions on classified forests will require a participatory approach.
