The objective of this study was to evaluate the relationship between the granulometric and chemical characteristics of the soil and the population structure of Euterpe edulis and analyze the distribution of individuals in a regenerating area of Atlantic Forest. A toposequence divided into top, middle, and lower positions was analyzed. Three 100 m² plots were established in each position and individuals taller than 1.3 m within these plots had their diameter at breast height (DBH) and total height measured. Individuals shorter than 1.3 m within 1 m² subplots installed within the plots were counted and classified according to their ontogenetic stage. Soil samples were collected from the 0-30 cm layer in each plot. A total of 187 individuals taller than 1.3 m were counted across the toposequence, with greater concentration in the top position (118 individuals). Among the ontogenetic stages, the seedling phase was the most representative (231 individuals), with the top position also showing the highest number of individuals at this stage (85%). It was observed that soil characteristics influenced the population distribution and structure of E. edulis. The principal component analysis (PCA) revealed that 64.32% of the total variation was related to soil characteristics. Each soil variable showed varying degrees of correlation depending on the position in the toposequence. However, higher potassium and clay content positively correlated with the species' distribution and population structure in the study area.
