Floristic Diversity of Residual Forest Fragments of the Dassioko Classified Forest (South-west of Côte D'ivoire)

Abstract

Background and Objectives: Scientific data on the floristic diversity of the residual forest fragments of the classified forest of Dassioko are lacking in Côte d'Ivoire. This study was conducted to improve knowledge of residual forest fragments in the classified forests of Côte d'Ivoire. Materials and methods: In order to characterize the different types of land use in the Dassioko classified forest, a raster image of the study area was downloaded and image processing was performed. Plots were set up, and floristic inventories were conducted in the plots. The analyses were carried out through the richness, floristic composition, and structural diversity of the vegetation Main results: This study identified 5 land use classes in the Dassioko Classified Forest. These are natural forests, forest plantations, crops, bare soil/new clearings, and water bodies. The residual forest fragments of the Dassioko Classified Forest contain 119 plant species divided into 46 families and 110 genera. The dense forests contain a large number of species. In the area, we note the presence of 12 vulnerable species according to the IUCN red list. The distribution of stems by diameter classes presents an inverted J shape. Conclusion: The floristic diversity in each of the zones is significant with a number of special status species that justify the importance that the Dassioko forest could have in conservation if a rehabilitation plan is put in place before the destruction of the entire forest.
