ABSTRACT
Studies on seasonal semideciduous forests (FES) are required in order to characterize the structure and verify the formation of patterns, also comparing the floristic composition among fragments. A remnant of FES, in Uberada, MG, was assessed by surveying twenty-five plots (20 × 20 m each) totalizing one hectare. All living trees with circumference at breast height (1.30 m above the ground) ≥ 15 cm were recorded. common phytosociological parameters and floristic similarity with other FES remnants were calculated. A total of 805 individuals were surveyed, representing 90 species. Micrandra elata (Euphorbiaceae) was the most important species in the community, followed by Galipea jasminiflora (Rutaceae). Besides the low relative density of pioneer species, the high basal area (45.8 m2 ha-1) and the peculiar flora are evidences of a mature and well preserved forest. The similarity analysis resulted in four distinct groups, related to geographical regions, and apparently, floristic similarity is higher among well preserved forests.
