Abstract

The aim of this study was to calculate the ratio of Liocourt and evaluate the diameter distribution in natural forest with 84 hectares of Araucaria angustifolia serving as a parameter for its management in a farm of 176 hectares, located in White Stone Farm, Lages, Santa Catarina State, Brazil, to achieve the concept of balanced forest. Diameter distribution behaved as expected for native forests, generating a distribution curve in J-shaped, showing that it is a forest inbalanced phase of succession as it has lack of trees in higher  diameter classes. The value of the ratio of Liocourt was 1.33, similar to other studies with native forests. By using the ratio of Liocourt would it possible to remove 54 trees per hectare in all classes of frequency, to a desired maximum diameter of 35 cm with a reduction of 7.4 m² ha-1 of basal area or 620.8 m² to the  settlement, avoiding the stagnation of the forest and 39 trees per hectare for the maximum diameter of 40cm with a reduction of 5.27 m² ha-1 of basal area or 442.7 m² for the forest.
