The present study aimed to determine the accumulated carbon potential in the arboreal stratum of a Lowland Evergreen Forest in the Cuyabeno Fauna Production Reserve. A conglomerate of one hectare was established, subdivided into 25 sampling units of 20 x 20 m. The floristic composition, the index of ecological importance at family and species level, and the aerial biomass were determined through allometric equations, biomass importance value and carbon stored potential in the arboreal stratum. It was determined that the forest in the study area stores 392.1 ± 2.35 Mg ha-1 of biomass and 196.05 ± 1.17 Mg C ha-1 in 685 ind ha-1 with D 1,30 ≥ 10 cm distributed in 13 orders, 19 families, 35 genera 43 species. The families with the largest number of species were Fabacea, Moraceae, Lauraceae, among families that store the largest amount of carbon stood out: Lauraceae (35.6± 0.7 Mg ha-1), Chrysobalanaceae (34.5 ± 5.3 Mg ha-1), Fabaceae (23.6 ± 0.52 Mg ha-1), Sapotaceae (22.6 ± 0.6 Mg ha-1), Arecaceae (21.99 ± 0.25 Mg ha-1) which accumulate 70.4 % of carbon retained in the forest aerial biomass. The accumulation of biomass is determined by the age of each biotype present in the forest, the density of its wood and the abundance of individuals. According to its structure, it is evident that the biomass is self-replenishing in the process of development with a tendency towards growth, biomass productivity and carbon sequestration.
