This study modeled the diameter growth of Araucaria angustifolia, Cedrela fissilis, and Ocotea porosa as a function of age and analyzed how these factors are related to diameter distribution. This analysis was used to describe behavior in terms of age and lifespan, and also determined periods of technical growth stagnation for each species. Diameter growth was evaluated via partial trunk analysis using increment cores from 30 trees per species in six study locations in southern Brazil (totaling 480 cores), collected in proportion to diameter distribution. Twelve biological models were utilized to estimate diameter growth as a function of age of the species in the different locations. The Weibull probabilistic density function with three parameters was adjusted to represent the diametric structure and indicate carrying capacity. Distinct ages were identified in the different study lo- cations, indicating successions in separate periods during the past as well as locations with the least alterations (oldest successions). The diameters at the technical age of stagnation and carrying capacity were found to be generally similar, demonstrating the relationship between diameter structure and diameter increment. Maximum vigor in the three species was found to occur at diameters considerably smaller than the maximum value, sug- gesting that attainment of significant ages and diameters may not fully reflect the inherent potential of all in- dividuals within the species under study. The maximum diameter increment vigor in the species under analysis was observed during the early stages of development, and tended to diminish in the subsequent phases.
