Abstract: The objective of this work was to analyze the floristic composition, forest structure and forest management potential in an area of dense rainforest for future use. To this end, a forest inventory was carried out by sampling 20 plots of 20x250m, measuring all individuals with DBH ≥ 0.10m. An analysis of the floristic composition, the Shannon-Wiener diversity index and the Pielou evenness index were carried out to assess the vegetation diversity. The analysis of the forest structure was based on absolute values of density, dominance, frequency and importance value. To analyze the potential for forest management, the diametric distribution and volumetric estimation were analyzed. 924 individuals were sampled), represented by 32 botanical families, 73 genera and 89 species. The study area is characterized by high floristic diversity (H'= 3.50), few dominant species (J = 0.78) and many species of low abundance. Of the commercial species identified in the study, ten are among the fifteen species with the greatest importance, possible for sustainable exploitation.
