Understanding the influence of fragmentation on the behavior of forest essential elements in different vegetation formations is fundamental for the definition of conservation strategies. In this study, the aim was to evaluate the influence of the edge environment on the phytosociological structure of a fragment of Open Ombrophylous Forest, in Rio Largo, Alagoas. Five transects of 10.0 x 100.0 m were subdivided into ten 10.0 x 10.0 m plots to collect the data. All tree individuals with Chest Height Circumference ≥ 15 cm were sampled, measured and later identified in the herbarium of the Institute of the Environment of Alagoas. For the analysis, the phytosociological parameters Shannon-Wiener diversity (H'), Pielou equability (J') were calculated after defined the successional classes and dispersion syndromes of the species sampled. The edge effect was analyzed by comparing the richness, diversity, equability and number of individuals in the interior and at the edge of the fragment, using the Venn diagram technique. There were 581 arboreal individuals, of which 434 were identified as belonging to 20 families, 24 genera and 30 morphospecies. Among the raised species, there were higher occurrences of early secondary (46.67%) and late (23.33%), as well as those of zoocoric dispersion (53.33%). The diversity was 2.89 nats/ind., and the Pielou (J') equability was 0.8497. The edge environment did not influence the establishment of species. This may have occurred due to the environmental characteristics of the open ombrophylous forest.
