摘要
on this work we present the results of a forest dynamics study performed in a forest management system designed for small properties. the system prescribes cutting cycles of 10 years, harvesting intensity of 10 m3 ha-1 and animal traction for skidding. the forest growth was 1 m3 ha-1 year-1 adequate to the proposed cutting cycle and harvesting intensity. the damage produced by the forest exploitation represented 5 % of the total basal area of the forest and the mortality rate four years after exploitation was 3.2 %.
