摘要
The objective of this work was to study the floristic composition and structure of the Cerrado (Brazilian savannah), focusing on the tree and shrub strata. A total of 30 plots (10x10m) were set up, distributed in 10 contiguous blocks where individuals with a minimum PBH of 10 cm were sampled. A total of 1,107 individuals were sampled. Such individuals belonged to 33 families and 88 species, showing high values of richness. Total basal area and total density were respectively 6,651m(2) and 3690 individuals per hectare. The values of diversity (3.868 nats/individual) and evenness (0.86) show high heterogeneity and low ecological dominance. The most important species were Qualea grandiflora Mart., Lafoensia pacari St. Hil., Magonia pubescens St. Hil. and Qualea parviflora Mart., which together represented 57.7% of VI.
