This study was conducted in Democratic Republic of Congo, in the province of Kwango, chiefdom of Pelende Nord in order to inventory the floristic diversity of forest islands. To study the vegetation, 15 transects 5 meters wide and 60 meters long were set up at random, with 5 transects per forest island. The inventoried plant species were identified using the combination of various identification keys, the botanical classification taking into account Angiosperm Phylogeny Group (APG IV).
The results obtained reveal 129 plant species divided into 35 families including 48 species with an average of 25.5 ± 14.4 in the first forest island, 39 species with an average of 20 ± 11.4 in the second forest island and 42 species with an average of 21.5±12.3 in the third forest island. The most represented families are those of Rubiaceae with 45.7%, Euphorbiaceae come second with 42.9% and Fabaceae in third position with 28.6%. This floristic richness shows that if these forest islands are well preserved, they can evolve into forest ecosystems by providing the same ecosystem services.
