Azagny National Park (ANP) is original by the variety and richness of its different types of vegetation. Among them, there are ancient cocoa and coffee farms abandoned since
1986 and 2000, which become secondary forests. This study that took place in the ANP aimed to characterize the floristic and structural diversity of these secondary forests according to the age and the type of crop preceding the abandonment. It has consisted in delimiting plots of 500 m² in which all woody individuals with dbh 5 cm have been counted and measured. The juvenile species with dbh < 5 cm have been identified and counted. A total of 3006 individuals belonging to 186 plant species, 148 genera and 67 families have recorded. The study showed that the older secondary forests were more diversified than younger ones. Secondary forests derived from cocoa farms abandoned in 1986 were more diverse than those resulted from coffee plantations with the same age, while we observed the inverse situation in the less aged secondary forests. The dominance of tree species confirmed the forestry characteristic of those spaces. The high proportions of juvenile species with dbh < 5 cm is the sign of a good
regeneration and a stability of these forests.
