The synergism of the components of a system is linked in selecting of the species to associate, which requires knowledge of their characteristics, such that it participating components to benefit from this integration. Getting to know the silvicultural characteristics and the form of the spatial distribution of native species can help in the management and implementation of silvopastoral system. This study evaluated the spatial distribution pattern of adult individuals of pequi (Caryocar brasiliense Camb.) in mixed pasture grasses and legumes in the Mato Grosso Pantanal. It was conducted a census of adult individuals of pequi in a remaining area of the biome cerrado, with geographical coordinates were 15º58'25.49 "S and 57º34'36.11" W. The mapping of individuals and the area were carried out by using the rectangular coordinate system (UTM) through georeferencing utilizing precision GPS and is subsequently exported to the TrackMaker 3.5. The individuals were analyzed regarding population and according to selection of crown area classes. The selection was made from the standard deviation (SD), where five classes of samples were established with one class represents the average, and the other four samples, the average most and least one and two SD. The distribution density of pequi population was analyzed by the Kernel estimator and the spatial distribution was calculated from the function K of Ripley, using the statistical software R, with the spatstat package. The number of neighbors near a random tree pequi is higher than expected for the Complete Randomness. Therefore, the population of Pequi showed a pattern of spatial distribution and aggregate when assessed by reference of the crown area was observed the distribution trees prone to randomness. The formation of aggregation trees and transition areas allows the passage of solar rays to the development of grasses having the necessary characteristics for driving the silvipastoral system.
