Exploitation of the biological resources and vegetation dynamics in the classified forest of the Upper Alibori in Benin (sector of the Arrondissement of Bagou)

The objective of this study is to show the impact of the exploitation of biological resources on the evolution of vegetal formations in the classified forest of the Upper Alibori (sector of the Arrondissement of Bagou) in Benin. The study is
based on the interpretation of aerial photographs with a field check and socioeconomic surveys. It shows that the main forms of exploitation are agriculture, herding, poaching, the exploitation of the forest and the use of medicinal plants.
