This research aims to analyze the state of conservation of gazetted forest, community forest and sacred forest in the southern Benin. To do this, two gazetted forests, two communities forests and two sacred forests were chosen. The evaluation of the dynamics of the forest cover has been made of the comparative diachronic analysis of land cover in 1982 and 2015. The phytosociological and forest inventories were carried out in the forests studied. The results revealed that the areas of forest classes are held and sometimes experiencing an increase in the sacred forests while these forest classes experienced a regressive development in gazetted forests. In community forests, regression and maintaining forest classes were observed. The average density of trees is the highest recorded in the sacred forest of Zannouzoun (352.50 trees / ha) and the lowest density is achieved in the community forest Togbin-Daho (104.60 trees / ha). The highest Shannon diversity index is obtained in the sacred forest of Kodjizoun (3. 08 bits) while the lowest value of this index is recorded at the gazetted forests of Pahou (1.96 bit). The state and the evolutionary trend of forest cover and ecological parameters show that the sacred forests and incidentally community forests are best preserved as gazetted forests. However, the small size of sacred forests requires to qualify this conclusion.

Abstract: (french)
La présente recherche vise à analyser l’état de conservation des forêts classées, sacrées et communautaires au Sud-Bénin. Pour ce faire, 2 forêts classées, 2 forêts sacrées et 2 forêts communautaires ont été choisies. L’évaluation de la dynamique du couvert forestier a été réalisée à partir de l’analyse diachronique comparative de l’occupation des terres de 1982 et de 2015. Les inventaires phytosociologique et forestier ont été réalisés dans les forêts étudiées. Les résultats ont révélé que les superficies des classes forestières sont conservées et connaissent parfois une augmentation dans les forêts sacrées alors que ces classes forestières ont connu une évolution régressive dans les forêts classées. Dans les forêts communautaires, la régression et le maintien des classes forestières ont été observées. La densité moyenne des arbres la plus élevée est enregistrée dans la forêt sacrée de Zannouzoun (352,50 arbres/ha) et la plus faible densité est obtenue dans la forêt communautaire de Togbin-Daho (104,60 arbres/ha). L’indice de diversité de Shannon le plus élevé est obtenu dans la forêt sacrée de Kodjizoun (3, 08 bits) alors la plus faible valeur de cet indice est enregistrée au niveau de la forêt classée de Pahou (1,96 bit). L’état et la tendance évolutive du couvert forestier et les paramètres écologiques attestent que les forêts sacrées et accessoirement les forêts communautaires sont mieux conservées que les forêts classées. Toutefois, la petite taille des forêts sacrées oblige à nuancer cette conclusion.
