HESS, André Felipe; MINATTI, Myrcia; FERRARI, Linamara  and  PINTRO, Benhur Ayrton. Araucaria forest management by the liocourt method, Painel municipality, SC. CERNE [online]. 2014, vol.20, n.4, pp.575-580. ISSN 0104-7760.

The aim of this study was to describe the diameter distribution and calculate the value of the Liocourt quotient 'q' for the species Araucaria angustifolia (Bertol.) Kuntze in natural forest, as well as evaluating competition indexes in a fragment with an area of 74.2 ha. Fixed area sample plots of 400 m2 were used in this study, totaling one hectare sampling area. Trees with DBH > 10 cm were measured in all plots and later distributed in diameter classes for the calculation of the density probability function and competition index. The forest showed a density of 228 trees per hectare and basal area of 19.49 m2·ha-1. The value of the "q" quotient for the forest was 1.1, indicating that the recruitment and mortality rates are in equilibrium. The calculated competition indices showed that the forest is in a competition stage, with Glover and Holl index of 0.9798 and 0.7069 m2 for the BALmod.
