This study had as objective determines the influence of the directions and of the distances of the center of the gaps on the behavior of the entrance, mortality and diameter growth of individuals with DAP > 5cm of a population of White Pitch (Protium pallidum Cuatrec.), and determining the diameter distribution of that species for three years of studies in a primary forest after selective exploration . For so much, five portions of 10m x 10m were implanted in each strip, where they were appraised the variables: Entrance (I%), Mortality (M%) and the Annual Current Increment (ACI) in diameter. The data were analyzed through the analysis of variance of three factors (directions, distances and the period of three years). The species had an index of initial entrance of 16.6%, with null mortality in the 1st year, presenting the largest values of diameter growth in the directions North and South, showing tendency to the stabilization and diameter distribution usually found at natural forests, with larger number of individuals in the smallest size classes.
