The carbon stock of tree species in plot VI of the CIEFOR (Central Forestry Institute) of the Faculty of Forestry Sciences, Puerto Almendra, was evaluated. Its floristic composition is made up of 602 individual trees, 119 tree species, and 33 botanical families, the Lecythidaceae family and the speciesEschweilera decolorans Sandwith are the most representative. A total of 195.45 t/ha of biomass and a carbon stock of 97.72 tC/ha were estimated. Eschweilera decolorans Sandwith with 37.65 t/ha of biomass and a carbon stock of 18.82 tC/ha, followed byAlchornea triplinervia (Spreng.) Müll. Arg. with 14.16 t/ha of biomass and a carbon stock of 7.08 tC/ha and Eschweilera rufifolia S. A. Mori It has 13.37 t/ha of biomass and a carbon stock of 3.79 tC/ha. The biomass and carbon stock maintain a 100% relationship between tree species. The statistical test tells us that it does not have a normal d...
