<br/><br/> <br/><br/>Abstract<br/><br/>We investigated the spatial distribution of population data and diameter classes and modeled the diameter structure<br/>of Vouacapoua americana Aubl. (Acapu) trees in a community forest management area. A forest census of trees with<br/>diameters ≥ 33 cm was carried out in the 2015 Annual Production Unit (APU-2015). Ripley’s univariate K function<br/>and the global Moran’s index were used to describe spatial autocorrelation. Three harvest intensities (50, 70, and<br/>80%) were simulated for the potential trees. The Weibull (3P) function provided the best performance to describe the<br/>diameter distribution of the original tree population, as well as in the harvested 50 and 70% intensities. In general,<br/>the spatial pattern of V. americana was aggregated. However, other natural factors, as population size, dynamics,<br/>geographic distribution, should be used as indicators for forest management and conservation of the specie.<br/><br/>Keywords: conservation of species, dense tropical forest, Vouacapoua americana, Weibull function.
