“…Achieving sustainable yields requires species-specific management of timber resources, in which the different growth strategies of tree species and the varying site conditions are considered. Unfortunately, species-specific and site-specific management criteria based on wood growth data in the tropics are quite rare (Stahle et al 1999;Schwartz et al 2002;Sokpon and Biaou 2002;Nebel and Meilby 2005;Schöngart et al 2008). For Amazonian forests, the restrictions in felling cycles and MLDs established in IN number 5 of IBAMA are estimations which are not derived from scientific data.…”

“…Parmi les espèces principales étudiées, seul Dialium guinense présente une asymétrie gauche (proportion élevée de jeunes individus en comparaison avec les individus âgés) et rassure de ce fait sur une évolution positive (augmentation de l'abondance) de sa population. Par contre, pour Afzelia africana, essence de valeur commerciale, un vieillissement de la population est bien noté, en conformité avec d'autres études (Sokpon, Biaou, 2002 ;Sinsin et al, 2004) constatant la faible régénération de Afzelia africana dans les différentes zones climatiques du Bénin, tout en avançant l'hypothèse selon laquelle le problème de régé-nération de l'espèce serait dû à l'inexistence d'une densité optimale de gros sujets sexuellement matures.…”

“…However, these time and diameter limitations are estimations or legal restrictions rather than being derived from scientific data. The definition of speciesspecific and site-specific management criteria based on wood growth data and structural analysis of the natural stands in the tropics is quite rare [20,30,32]. In this study we show how management criteria can be defined on species-specific basis by growth models employing dendrochronological analyses.…”

“…Simulations of diameter growth curves based on tree-ring data so far exist only for some tree species in Cameroon [43], Zimbabwe [33], Tanzania [30], Venezuela [41] and the Central Amazonian floodplains [28,42]. The majority of growth models are based on indirect methods such as repeated diameter measurements of trees from different size classes, this performed during some years in permanent sample plots to simulate growth trajectories [6,18,20,31,32]. These models however represent only a short period of tree growth, while tree-ring analysis applied in this study describes the growth of an individual over its whole life span.…”
