The aim of this study was to inventory plant biodiversity and to evaluate the carbon sequestration potential of the Misomuni forest massif. An inventory of all trees with diameter at breast height (dbh) ≥ 10 cm measured at 1.30 m height was performed. The aerial biomass (AGB) was used for estimating the stored CO2 and its carbon equivalent. 88 plant species belonging to 71 genera and 32 families were inventoried. Fabaceae family displayed the highest number of species and genera. The highest basal area values were displayed by Scorodophloeus zenkeri (7.34 ± 2.45 m2 /ha), Brachystegia laurentii (5.82 ± 1.94 m2 /ha), Entandrophragma utile (5.28 ± 1.94 m2 /ha), Pentadesma butyracea (4.53 ± 1.51 m2 /ha). The highest values of stored carbon and their carbon equivalent were observed in Pentadesma butyracea (15.13 ± 5.00 and 50.55 ± 16.85 t/ha), Picralima nitida (7.02 ± 2.34 and 23.66 ± 7.88 t/ha), Strombosia tetandra (6.56 ± 2.18 and 22.10 ± 7.36 t/ha). The Misomuni forest massif is thus much floristically diversified and plays a significant role in the sequestration of CO2. The total AGB of the inventoried trees is 183.78 ± 61.26 t/ha corresponding to stored carbon and carbon equivalent of 96.63 ± 32.21 t/ha and 289.92 ± 96.64 t/ha respectively. The protection of this ecosystem is highly needed for combatting climatic changes at local, national and regional scales and for the conservation biodiversity habitat.
