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. |
