Abstract

In order to contribute to the sustainable management of the Azagny National Park (ANP) in southern Ivory Coast, a study on forest dynamics after abandonment cocoa plantations was initiated. The target of this study was to assess the level of recovery of the ancient cocoa plantations. To this end, two types of ancient cocoa plantations have been studied. The first is an ancient plantation abandoned in 1986 and the second is a plantation abandoned in 2000. These ancient plantations have now become secondary forests. The floristic and structural parameters as well as recovery parameters of secondary forest were compared with those of an intact forest which is an old growth forest on dry land. The method used is the surface survey which consisted to delimit plots of 500 m² in each of the three types of space. A total of 470 species in 300 genus and 97 families were recorded. The old growth forest is more diversified than the secondary forests grown from cocoa. There is no floristic similarity between secondary cocoa forests and old growth forest. The basal area, pioneer index and regeneration potential of secondary cocoa forests are statistically equal to those of old growth forest. This indicates that ancient cocoa plantations are evolving towards the forest.
