SUMMARY:

The BDq method is based on the concept of balanced forest and its application as determination of selective logging leads the population to a remaining stock promoting the maintenance of the diameter structure. The work aimed to apply the BDq method in an area subjected to Forest Management. Through 20 m x 20 m sample plots, a forest inventory was carried out in an area of 4,400 m². Three management alternatives based on the BDq method were proposed, with 40% (T1), 50% (T2) and 60% (T3) stem reduction. 1,680 woody individuals were inventoried in 10 families, 18 species and 16 genera. In T1, with a reduction of 40% of the total basal area (8.40 m²ha^-1) there is an estimated harvest of 1,873 stems, being more representative in the center of the diameter class 2.45 cm (1126 stems). The estimated harvest volume was 39.42 m³ha^-1. At 50%, it allowed a permanence of 39.76% of the stems and an estimated harvest of 60.23% of the individuals, representing a total of 1,012 stems. The estimated harvest volume was 39.65 m³ha^-1. In T3, with a reduction of 60%, it allowed a permanence of 37.50% of the stems and a harvest estimate of 62.50%, representing a total of 1,050 stems between the classes. The estimated harvest volume was 40.61 m³ha^-1. Taking into account the dynamics, ecological succession and commercial exploitation, it was observed that the combination that showed the most effective results was that of management Scenario 1, due to the high number of individuals able to silvicultural activities, thus ensuring the ecological succession, of the area and subsequently its dynamics.
