Abstract: Objective : This study aims to make a structural description of the vegetation of the Orumbo Boka forest (Ivory Coast) in order to provide useful baseline data for the rational subsequent management of this classified forest. Methodology and results: A botanical inventory was carried out in 500 m2 (25 m x 20 m) plots set up in each of the habitats of the classified forest. Within the plots, arborescent individuals with a Diameter at Breast Height (DBH) greater than or equal to 2.5 cm at 1.30 m above ground level were counted. For individuals with buttresses and stilt roots higher than 1.30 m, the diameter was measured at 50 cm just above the buttresses or stilt roots. For branched individuals less than 1.30 m high, each stem was considered as a plant in its own right and measurements were made on each of them. This study identified a total of 4416 individuals of trees with a DBH greater than or equal to 2.5 cm on 2.3 ha with a higher average density at forest level (2050.4 ± 288.3 individuals / ha) than the two other habitats which are fallow and cultivated area. Conclusion: these results reveal the specific richness of this classified forest, which is sufficient to justify its protection.
