Composição florística e fitossociológica do cerrado sensu stricto no Parque Estadual da Lapa Grande, Montes Claros, MG

Abstract

The Lapa Grande State Park (PELG) is situated in the north of Minas Gerais, it is in the Cerrado that has a unique diversity. A phytosociological and floristic study of the cerrado sensu stricto was made with the purpose of characterize the plant community and selected of the most representative species of vegetation. The plots had 400 m² (20x20m) and it was measured all trees with the diameter of tree base above 3 cm. It was collected the diameter, total height and the individuals botanical material. The data were processed using the FITOPAC software getting as result the phytosociological and floristic parameters. The species that showed higher values in the categories of abundance, spatial distribution, density, frequency, and IVI were classified according to the dispersal syndrome and characterized by its phenology. The Fabaceae, Vochysiaceae, Myrtaceae and Malvaceae families represented 51.24% of all sampled individuals. The Shannon index to the area was 4.12 nats.individuals-1, being considered as high index when compared to other studies. In general, 22 species increased fruiting between August and February and flowering increased from July and decreased in September. In this respect, the species showed dispersion mostly anemocoric.
