    The objectives of this study were: to examine, characterize and interpret the spatial pattern of Tornillo (Cedrelinga cateniformis) and Guabilla (Inga sp.) And to analyze their relationship with some spatial covariates in the Amazon region, Peru. The statistical analysis was carried out through the tools of the analysis of spatial point patterns, which provide a set of methods, which based on the georeferenced location of the species allowed to estimate: the intensity of points, the function K (r) and L (r) and perform hypothesis tests of the underlying point process in the study area. Likewise, from the formulation of models, the relationships with a set of spatial covariates were evaluated. The methods used show a non-homogeneous spatial pattern of all the Tornillo and Guabilla trees present in the study areas, clearly perceiving the aggregation of points at short distances (approximately 15 meters) and significant in the entire range studied. Also, it was determined that the intensity of Guabilla is related to the distance to the seedbed, while the Tornillo is also related to the altitude above sea level and the distance to the rivers, which could be seen in at least one of the four study areas.
