Quantifying the tropical forests’
carbon stocks is presently an important component in the implementation of the
emerging carbon credit market mechanisms. This calls for appropriate allometric
equations predicting biomass which currently are scarce. In this study, we
aimed to estimate above-and below-ground biomass and carbon stocks of trees, and to identify the
variation in diameter-height allometry of Ipendja mixed terra firme lowland tropical forest’s
trees. The study area is located at Ipendja forest management unit (UFA), close
to Dongou district (Likouala Department), in Northern Republic of Congo. This
study combined forest inventory data of 1340 trees recorded from eight studied
plots distributed in two sites, respectively Mokelimwaekili (i.e., Old-growth forest) and Sombo (i.e., Selective logging forest). Trees
measurements were done with rectangular plots, each 25 × 200 m
(i.e., 0.5 ha, 5000 m2).
In eight studied plots (4 plots per site), only trees with DBH≥10cm were measured and identified. 1340 trees founded were belonged 145
species and 36 botanical families (n = 733 and
