Structure des peuplements ligneux des formations végétales de la forêt sacrée de Nassou en zone soudanienne du Bénin

Abstract: RESUMELes forêts sacrées connaissent une dégradation proportionnelle à l'augmentation des populations riveraines et du développement de leurs activités socioéconomiques. La présente étude avait pour objectif d'étudier la structure forestière de la forêt sacrée de Nassou, et d'évaluer les possibles effets anthropiques sur les caractéristiques dendrométriques et écologiques de 4 essences fruitières ligneuses. A cet effet, un inventaire forestier de 60 placettes carrées de 900 m 2 réparties suivant un échantillon… Show more

“…Within the considered plant formations, none of the target species is recognized as ecologically weak, implying that they contribute moderately to the ecological value of their respective habitats. Similar results have been reported for other tropical woody resources such as Afraegle paniculata, Diospyros mespiliformis, Kigelia africana, and Vitex doniana by Agbani et al [20]. Each of these species holds socio-cultural significance among local populations and has been identified as providers of ecosystem services, emphasizing the importance of their preservation within the Forest Management Site of Tiogo.…”

“…This variance may be attributed to differences in substrate conditions influencing these vegetation groups. The distribution of woody species is known to be influenced by climatic and edaphic factors [20]. As noted by Ganame et al [21], the composition and structure of woody vegetation exhibit considerable variability from one locality to another, influenced by environmental factors and anthropogenic disturbances.…”

“…The distribution according to the size (circumference) of all the forests of the two areas shows that the population has a reversed "J" shaped structure trans- Weibull distribution clearly show that this is a habitat where the predominance of a species or a restricted group of species is noted. This characteristic is in adequacy with the ecological characteristics of a strongly disturbed area [29].…”

“…Les résultats de la présente étude montrent que l'indice de diversité de Shannon-Weaver (4,61) et celui d'Equitabilité de Piélou (0,83) sont élevés dans la parcelle étudiée comme dans l'ensemble des forêts tropicales. Selon Agbani et al (2018), les paramètres dendrométriques et écologiques varient globalement en fonction des formations végétales et en général, les plus fortes valeurs sont obtenues en forêt dense. Ces valeurs élevées de l'indice de diversité de Shannon-Weaver traduisent une grande diversité spécifique et correspondent à des conditions de milieu favorable permettant l'installation de nombreuses espèces représentées par un petit nombre d'individus (Choula et al, 2013 ;Taffouo et al, 2017).…”
