Abstract: The present study aimed to evaluate the biological carbon storage potential of Guiera senegalensis stands in Cameroon. Sampling was done in 180 plots of 2500 m2 (50 m × 50 m) (40 ha) in the G. senegalensis stands. The destructive and non-destructive method was used to estimate the amount of carbon in different biomasses. A laboratory analysis was done to assess soil carbon by the Walkley and Black method. The experimental device installed is a split plot with 180 repetitions. The result reveals that the aboveground carbon is ≥5.20 ± 0.65 Mg C/ha in the two regions. The belowground carbon is ≥1.48 ± 0.23 Mg C/ha in the two regions. The herbaceous carbon is ≥2.03 ± 0.00 Mg C/ha in the two regions. The litter carbon is ≥0.36 ± 0.04 Mg C/ha in the two regions. The dead wood carbon is ≥0.47 ± 0.00 Mg C/ha in the two regions. The fine roots carbon is ≥0.10 ± 0.00 Mg C/ha in the two regions. The soil carbon stock is ≥5.45 ± 0.02 Mg C/ha in the two regions. The total carbon stocks ranged from 16.83 ± 1.03–64.76 ± 2.71 to 19.95 ± 1.33–80.65 ± 4.55 Mg C/ha in the Far North and North regions, respectively. CO2 emissions are ≥61.76 ± 3.78 Mg CO2/ha in the two regions. These results therefore confirm the contributing role of G. senegalensis stands studied in the fight against the mitigation of climate change in Cameroon.
