Structural characteristics of a forestry facies at Cynometra pedicellata De Wild. and Pterocarpus soyauxii Taub. on the Loufézou island in the Plateau of Cataracts (Congo Republic)

The general aim of this study is the knowledge of the phytodiversity of the forestry island of the Congo River, Loufézou, in order of a protective management. The adopted methodology is the one of the vegetation structural marks, concerning the dendrometrical measurements of all the individuals with a DBH > 10 cm. From eight statements covering an area of 0.5 ha, the forestry facies achieves presents a basal area of 37 m2/ha. This floristic basic of 19 species, achieved by 372 individuals, is dominated by the Fabaceae. The diversity indexes of Shannon & Weaver and of Piélou are respectively of 1.39 and 0.47 bits. Cynometra pedicellata De Wild. and Pterocarpus soyauxii Taub., are the two species which impose the structural large-scale,, reaching the most highest values in importance value indexes, with respectively 145.5 and 28.9 %. These data complete and refine the knowledge of this insular phytodiversity, essential basis in order to elaborate management plans in view of a lasting management.
