The floristic and ecological aspects of the tree vegetation of a remnant forest in the Godoy Forest State Park were studied. Two hundred and six native species of the region occur in the park. Comments on ecological aspects, such as dispersion, structure of vegetation and succession of these species, are provided. An analysis of the ecological parameters indicated that the occurrence of late secondary and climax species (55.8%) was greater than that of pioneer (6.8%) and early secondary species (34.5%). This seems to indicate a predominant dependence of biotic factors on the abiotic factors and an advanced stage of succession.
