Many tree species in tropical natural forests are unknown or little studied, especially regarding their ecological, silvicultural and wood use characteristics. Studies on the dynamics of these species are necessary to assist in planning their uses, with minimal impact on the ecosystem, aiming for economic, ecological and social benefits. The present study aimed to evaluate the population dynamics of the species Laetia procera (Poepp.) Eichler over a period of 31 years in a dense managed terra firme forest in the Eastern Amazon, aiming at sustainable timber production. Abundance, dominance, frequency, importance value index, diameter distribution of trees, recruitment, mortality and annual periodic increment in diameter were evaluated. The structure of the L. procera population benefited from the increment in solar radiation in the forest, due to logging and thinning, favoring its growth and establishment in the area until the end of monitoring. Its dynamics over the 31 years of evaluation, based on the evaluated parameters, can guarantee its conservation in managed forests and suggest its inclusion in polycyclic management programs, aiming at sustainable timber production.
