Forest management accounts for 30% of the impacts that tropical forests suffer. The study of forest dynamics allows measuring the impact of forestry interventions. For that this investigation evaluates the forest dynamic in terms of mortality and recruitment of trees with DBH >= 32 cm, as well as the mortality in each diameter class of 2 physiognomies: ombrophylous dense forest (ODF) and open ombrophylous forest with liana (OAFL), in the oriental Amazon region; through 13 permanent monitoring plots (PPM) of 50 x 50 m (2,500 m(2)) located in a annual production unit (APU) under reduced impact management, during the period of 2014-2016. We determined that mortality and recruitment rates were not statistically different, although they were higher for OFD. Recruitment was higher in the OFD. The mortality due to management showed statistical variations according to the diametric class. These variations in dynamics are important to be taken into account in the construction and execution of management plans.
