The objective of this study was to evaluate the edge effect on arboreal component of two Atlantic Forest fragments, in the Watershed of Tapacurá River, Pernambuco. For the sampling of the adult component 15 plots of 10 x 25 m were plotted and subplots of 1 x 25 m for the regeneration. The plots were arranged in three environments, with five sampling units each, according to distance from the edge. Comparisons between the environments were performed by specie composition, Venn diagram and cluster analysis. The greatest richness was observed in the area farther from the edge and the greatest number of individuals near the edge. In the Mata da Onça, the farthest edge environments were similar, but different in composition and structure as compared to the nearest environment. However, in the Mata da Buchada the first two environments near to the edge were similar. The interaction between the human environment and the fragment affects the arboreal community in the fragment edges.
