Abstract: In Republic of Congo, the forest plantations are dominated by both exogenous and endogenous tree species. This study estimated carbon stocks for above- and below-ground biomass around the Bambou-Mingali forest plantations, in the Republic of Congo. It applied allometric equations to measure above- and below-ground biomass carbon stocks in six rectangular plots of 5000 m2 (200 m × 25 m). About 1763 trees were measured and recorded where 1360 trees were within the 10 - 20 cm diameter class, 385 trees within the 20 - 30 cm diameter class and 18 trees within the 30 - 40 cm diameter class. Furthermore, the average carbon stock was 144.9 t C ha−1 for aboveground biomass (AGB) or 81% and 33.8 t C ha−1 for belowground biomass (BGB), or 19%. Similarly, results also showed total carbon stocks in all biomass to be 869.7 t C for AGB and 203.3 t C for BGB. Bambou-Mingali forest plantations are an important carbon sink and can therefore play a key role in the creation of carbon sinks, climate change mitigation and emergence of the green economy in the Republic of Congo.
