- Abstract
The objective of this study was to evaluate the changes in floristic composition in a fragment of Seasonal Semideciduous Forest. In the first inventory carried out in 2011, 25 plots of 10 × 40m were allocated. All living individuals with a breast height diameter ≥ 5 cm were measured. The second inventory was carried out in 2015, using the same criteria of the previous inventory, thus, were incorporated the new individuals (recruits) that reached the minimum diameter of inclusion. The floristic composition changes, the mortality of the individuals was superior to the recruitment, there were loss of five species and increase of two species. The number of species and the density of individuals varied over time. The species that disappeared were represented by few individuals. The loss of species reflected in the diversity index of Shannon (H ') and Pielou equability, (H' went from 4.05 to 3.99 and Pielou J 'equability from 0.83 to 0.82), in the first and second inventory respectively, even so, the values point to a high floristic diversity. The changes in floristic composition were not significant, the loss of species was related to the less representative in number of individuals, among the inventories the forest remained stable.
