The objective of this work was to recover growth patterns in an over-stocked stand of trees, using a stand of Araucaria angustifolia as a case study to develop an understanding of tree development over the long term. This will be useful in planning silvicultural intervention and in the management of new plantation of this species. An overstocked stand of Araucaria angustifolia (Bertol.) Kuntze was evaluated in Campo Largo, Paran´a, Brazil, in the National Forest of Açungui. At the time of the study, it was 65 years old and had been through a single thinning. The area was sampled using circle plots defined by a modified Prodan method, using 46 trees in three development classes (DC) were defined as sampling plot centers: DC-1 (10 ? dbh < 30 cm), DC-2 (30 ? dbh < 50 cm) and DC-3 (50 ? dbh < 70 cm). Fourteen disc samples were obtained from each plot center tree and increment core samples were obtained from competing trees, totalizing in 296 trees sampled. The trees presented similar increment in the first 5 years. At 10 years the DC-3 trees presented higher growth than the others, indicating when the first thinning should be performed. The two smaller classes (DC-1 and DC-2) presented growth differentiation only after 20 years, suggesting that thinning during this period could have been successful. The DC-3 trees showed an increment greater than twice of that observed in DC-1 trees for those trees in the diametric class of 10 to 20 cm. The average increment stabilized even in the largest trees (DC-3) from 40 cm in dbh. The suggested procedure, using a competition index and dendrochronological analysis, allowed for the identification of growth patterns in overstocked stands. Analysis using dendrochronology and competition index allowed better understanding of the growth rate of an unmanaged stand. In our case study, these patterns made it possible to identify the correct period for the first thinning. These results will provide a useful basis for management of future A. angustifolia plantations.
