Enjeux et amélioration de la gestion des espèces du genre Entandrophragma, arbres africains devenus vulnérables

Abstract: Par la qualité de leur bois et leurs nombreux usages traditionnels, les espèces du genre Entandrophragma font l’objet d’une intense exploitation, susceptible de compromettre leur pérennité en l’absence de gestion durable. La présente étude dresse un état de la situation de cinq espèces commerciales principales de ce genre : Entandrophragma angolense, E. congoense (souvent assimilée par erreur à E. angolense), E. candollei, E. cylindricum et E. utile.

“…The experimental site of forest plantations is situated in Yangambi (figure 1) in the central Africa depression of the DR Congo at 0°49'N, 24° 29'E limited between 0.7545157N-24.3944551E and 0.8553569N-24.5200252E and 470 meters of altitude mean on sandy clayey to clay sandy oxisoils of Yangambi (Y1) and Yakonde (Y2) soil series laid on the structural catena of Yangambi [1,7,18]. The biosphere floristic reserve of Yangambi covers 235000 hectares located in the ecological region of Yangambi which occupies about 444 000 hectares, dominated by the evergreen dense forests of Gilbertiodendron dewevrei, Brachistegia laurentii, Pericopsis elata and Scorodophleu szenkeri [5,17,19,24].…”

“…They grow preferably in Guinéo-Congolaise region of African dense humid forests [3,25,26]. E. cylindricum settled from dense forests onto fallows is requireless, prefers versant and plateau soils with pH atypically high, dry well drained, with the rainfall ranged between 1200 and 2500mm and the average temperature from 15 to 32°C [17,25]. Meanwhile, Pericopsis elata is nitrogen fixing legume, characteristic of fertile soils, atypically acid, clayey, with weak exchangeable aluminum content, rich in magnesium and available phosphorus.…”
