Floristic changes in conventionally exploited forst areas in management plans, in the atlantic forest domain, Minas Gerais State-BrazilThe objective of the present study was to analyze the changes in the composition of species, in forest management areas having as control the legal reserve area, and it was carried out in fragments of semideciduous seasonal forests in the Zona da Mata Region of Minas Gerais State. Following the harvest of each FMP, the comparison between forest management areas and legal reserve areas showed that, in relation to changes in diversity of the FMP tree species, the verifiers ecological group, use group and rare species group indicated that the forest management areas of all the FMPs were statistically equal (P>0.05) to the legal reserve areas. The verifier species richness indicated that the forest management areas and the legal reserve areas of the FMP28 and FMP29 were statistically equal (P>0.05), whereas the FMP30 and FMP16 were statistically different (P<0.05). The verifier species diversity indicated that the forest management areas were statistically different (P>0.05) from the legal reserve areas in FMP29, FMP30 and FMP16 and statistically equal (P<0.05) in the FMP28. The greatest similarity of species occurred between the groups formed by the FMP29AMF and FMP29ARL, and the smallest similarity occurred between the groups formed by FMP29ARL, FMP29AMF, FMP28ARL, and FMP16ARL, FMP16AMF, FMP30ARL, FMP30AMF, FMP28AMF.
