Impact of land use type on the diversity of flora in the village of Akoikro in the department of Abengourou (Eastern Côte d’Ivoire)

In many African countries, particularly in Côte d'Ivoire, development policies often lead to the destruction of forest areas. Faced with this problem, environmental assessment is increasingly recommended to prevent potential bio-ecological and climatic imbalances. This study, conducted in the village of Akoikro, the construction site for the University of Abengourou, aims to evaluate the floristic potential of different land cover types in order to identify potential impacts related to the project. An inventory of woody plant species with a diameter at breast height (DBH) of at least 10 cm and a height of 2 m was compiled using a combination of surface survey and mobile sampling methods. The main results indicate the presence of numerous ecosystems, including lowland areas, forest remnants, gallery forests, and plantations. The study's flora comprises approximately 142 plant species, including 13 species of special status listed on the IUCN Red List. The flora is dominated by the Apocynaceae, Euphorbiaceae, and Rubiaceae families. Microphanerophytes are the most abundant, while Guinean-Congolese (GC) species constitute the majority of the inventoried flora. Well-preserved areas have the highest concentration of tree species, unlike areas subject to high human pressure.
