Abstract

The objective of this study was to calculate the ratio of Liocourt in natural forest with 50 hectares of Araucaria angustifolia. The diameter distribution behaved as expected for native forests, generating a distribution curve similar to an inverted-J. The forest showed 456 araucaria trees per hectare with diameter at breast hight (DBH) above 10 cm and basal area of 24.64 m² ha-1. The value of the Liocourt quotient was 1.3, and 54 trees per hectare with 40 cm of DHB can be removed, with a reduction of 2.70 m² ha-1 of basal area or 135 m² total basal area and 34 trees per hectare for a 50 cm of DBH with a reduction of 1.9 m² ha-1 or 95 m² total basal area. Considering only the commercial classes (DBH ≥ 40 cm) this withdrawal represents a reduction of 9.5% for the basal area to the diameter of 40 cm and 6.9% to the diameter of 50 cm.
