The plants used for every forestry produce is variable with the existence or abundance of the species and the sociologic and cultural consideration peculiar to each ethnic group like choice of fuel wood. The different exploitation forms more or less severe had been contributed to amplify the climatic dryness effects on forestry resources degradation. Fortunately, an evolution with manufactured products enable to adapt environment changes. There is an imperious necessity to document, consider and to improve indigenous knowledge of natural resources for sustainable development
