The aim of this study was to evaluate the life cycle and competition of Ocotea odorifera (Vell.) Rohwer in Mixed Rainforest. Understorey trees emerging from the Chapecó National Forest, SC, were selected. The diameter, crown projection and total heights of each sampled tree were measured. Samples with increment auger were obtained and the growth rings were analyzed to determine the growth in diameter. Competition indexes were calculated, hypsometric models were adjusted, and growth was adjusted for each height class (less than or greater than 11 m). The individuals were aged between 47 and 220 years, in diameters 17 and 90 cm at 1.30 m in height (DBH). The species is long-lived, with an average increment of 0.42 cm year-1. The average annual increment differs between classes of height and diameter, being smaller and stable for individuals who are under the canopy. The Glover and Hool index reflected this condition, indicating that trees with a smaller diameter are under greater competition pressure. The analysis of the competition indexes and the growth models, allow to establish a prognosis of the growth of the O. odorifera trees, serving as a subsidy to the management planning for commercial use and / or conservation.
