urban parks have a strategic importance fot the quality of life in urban centers, contributing to significant environmental and social services. knowledge of forest structure has helped to subsidize the maintenance of these parks. based on the phytosociological analysis of tree species in a semideciduous forest fragment (120 ha), this study assessed the conservation status of this remnant. we sampled all trees with cbh > 15 cm, present in 25 permanent plots (20 × 20 m), and classified the species as to successional groups and dispersal syndromes. we recorded 798 individuals in 98 species belonging to 37 families. early secondary species had the highest values of species richness , density and importance value, followed by late secondary species with the highest dominance, and pioneer species with low representation. regarding the dispersal syndrome, over 77% of the community is represented by species with zoochoric dispersal. these results increase the valuation of the "parque da matinha", reaffirming the importance of this urban park for the conservation of native fauna and flora, and supporting the need for public policies of park use by visitors.
