Distribution et dynamique de la flore ligneuse à la périphérie du Parc national de Waza (Cameroun)

The purpose of this study is to characterize the distribution of the woody flora and the spatio-temporal dynamic of the woody vegetation cover on the periphery of Waza National Park. The study was organized around two main complementary methods : (i) botanical inventories which made it possible to d...
