Considération des caractéristiques structurales comme indicateurs écologiques d’aménagement forestier au Togo (Afrique de l’Ouest)

The dry facies semi-deciduous forest islands of Togodo fauna reserve constitute one of the rare forestry ecosystems in the bare and highly anthropized landscape of the costal plain of Southern Togo. The structural analysis of these forestry islands is conducted through some forestry inventories in 4...
