The study was carried out in the National Park of Lobeke (Cameroon). It aimed to assess diversity and sequestration potential of some commercialized timbers under industrialisation pressure. We took place 37 transects of 5 ha each. All selected timbers of at least 5 cm of DBH were surveyed. 8, 619 individuals divided into 6 families, 6 genera and 9 species were recorded. Diospyros crassiflora (Ebene) was the most diversified species (ISH= 8.09); followed Terminalia superba (Frake; ISH= 2.08). Triplochyton scleroxylon (Ayous), Terminalia superba (Frake) and Entandrophragma cylindricum (Sapelli) were the biggest species of the flora with 549.01; 370.22 and 334.8 m² of basal area respectively. With a stock of carbon evaluated at 107.5 t C/ha, the ecological service from the selected species was estimated at 23,419,305 t of CO2 incorporated in their biomass as from now. In the context of REDD+, the conservation of forests are welcome in mitigating climate change for the humanity welfare.
