Implementation of REDD programs requires accurateestimates of forest carbon. This study reports biomass and carbon in a forestof the Nonuya-Villazul indigenous reservation (RVN) in the Colombian Amazon,based on a permanent plot of 6 ha. The local spatial variation of the biomassand the contribution of the undergrowth were evaluated, two factors that arerarely taken into account. A total average biomass of 336.1 ± 14.0 t.ha^-1was found; 11.5% is in the understory (DAP 1-10 cm) and 88.5% corresponds totrees with DBH ≥ 10 cm; large trees (DAP ≥ 70 cm) are few (4 ± 1ha) and have a low contribution to total biomass (6.8%) compared to othertropical forests. The biomass is within the range reported for the Amazonbasin, is superior to the Western Amazon and similar to the Colombian Amazon.Considering that the RVN has 208800 ha in unflooded forests, a total average of31.0 Mt C (95% CI 29.1 - 32.04) was estimated. These results allow to locatethe forests of the RVN in a global context and improve the forest carbonestimations in the Colombian Amazon.
