The cultivation practices of cocoa and coffee trees threaten the existence of the Ivorian forests. In order to elucidate the impact of these practices on the diversity of forest flora, we inventoried and analysed the spontaneous woody flora of three different categories of plantations of cocoa and coffee trees. The study proceeded in the classified forest of Monogaga, in the southwest of Côte dIvoire. The results of our study show that the plantations are relatively diversified. They contain endemic, rare and threatened species and preserve high tree density and basal areas. In fact, the analysis shows that young, upcoming plantations, in particular, have the greatest diversity. The same can be observed for intact and mature neighbouring secondary forests. Diversity in the categories of the oldest plantations is low and decreases over time. Agricultural practices in Monogaga thus constitute a medium-term threat to the preservation of forest flora diversity.
