A total of 25 plots of 20×20 m in each fragment were allocated and all living individuals with Circumference at Breast Height (CAP) ≥ 15.7 cm were considered. The Shannon-Wienner indices and the Pielou equitability were equal among sampled areas. The Jaccard and Bray-Curtis similarities were 20.7% and 41%, respectively, indicating a high β diversity. Non-metric Multidimensional Scaling (NMDS) resulted in two floristic groups, distinguishing the flora of Presidente Juscelino and Paracatu. These results showed that the areas are floristically different but resemble each other in terms of diversity and structure.
