The formation of homogeneous landscapes has become a problem in conservation biology, since these crops directly interfere in the dynamics of communities. Therefore, the objective of this study was to determine the floristic composition and structure of the natural regeneration of cerrado in the understory of Eucalyptus camaldulensis and verify whether the regeneration differs depending on the distance from the edges of the stand. The present work was carried out in the municipality of Montes Claros, MG. Two plots were demarcated for the survey, each subdivided into nine subplots of 10x10 m each, using the height e" 0.30 m as the inclusion criterion . A total of 2,413 individuals were recorded. In Plot 1, we sampled 914 individuals belonging to 63 species and 26 families; Eugenia dysenterica, Hymenaea stigonogocarpa, Calliandra sp. and Duguetia furfuracea were the most important species according to the Importance Value (IV). In Plot 2, 1,499 individuals were distributed in 30 families and 71 species, and the highest IVs were achieved by Cupania vernalis, Chamaecrista desvauxii, Pouteria ramiflora and Senna rugosa. The distribution of classes in height and diameter showed the majority of individuals in the lower classes demonstrating that area still reflect recent event regeneration. However, the results of this study indicate that there are distinct communities at the site and that Plot 2 is in a more advanced stage of regeneration than the Plot 1. This fact was confirmed by cluster analysis between plots and the differences in diversity and structural development of the vegetation in each plot.
