The objective of this work is to evaluate the impact of logging on forest dynamics in a managed native forest area. Pre-exploratory census of commercial individuals ≥ 45 cm in diameter was performed in two work units (TU), one explored and the other witness in 2004 and 2015. Recruitment and mortality were analyzed. The open area of the trails, courtyards and secondary roads was calculated by making maps using the geographic information system (GIS). Forest structure indices were calculated as a function of abundance, basal area, volume and areas explored and control. The volume, basal area and mortality in the explored area was lower than in the control area. Recruitment was 23% in the exploited area and 22% in the control area. The area impacted by the primary and secondary drag trails was 6,135 m² and 16,570 m², while the secondary road and stockyard were 18,568 m² and 2,874 m². Planning of forest exploitation contributed to reduce damage to tree species ≥ 45cm in diameter.
