Analysis of Specific Woody Dynamics in the Mayo Sorawel Watershed (North Cameroon)

GANOTA Boniface | TOUMBA TIZI PhD

Abstract: The woody cover in the Sudano-Sahelian zone of North Cameroon includes Sudanian and Sahelian species. In the Mayo Sorawel watershed, the demographic pressure of needs and the selective cutting of woody trees by the Chaux Roca Company are causing a deterioration in woody diversity. The purpose of this article is to analyze the state of woody diversity in the watershed. On the basis of botanical surveys, surveys of 999 actors in timber operations, the Shannon diversity index, Landsat 2016 images and field surveys, it appears that the diversities are low H '<3 bit in the degraded vegetation that already covers 83.68% of the watershed. Techniques for exploiting prized species are unsustainable. Given the importance of biodiversity in the balance of ecosystems and local economies, policies to restore woody diversity are necessary in the watershed.
