<br/><br/> <br/><br/>Abstract<br/><br/>This study aimed to evaluate the changes in the floristic composition at the Cerrado (Brazilian Savannah) stricto<br/>sensu and Cerradão (xeromorphic forest) phytophysiognomies. In the first inventory in 2010, 15 soil plots of 20 × 50 m<br/>in the Cerrado stricto sensu (CSS) and 10 soil sample plots of 20 × 50 m in the Cerradão (CD) were separated, and<br/>individual samples with diameter at soil height ≥ 5 cm were measured. The second inventory, conducted in 2015,<br/>used the same criteria. A fire hit both phytophysiognomies after the first inventory. Species loss and a mortality rate<br/>higher than recruitment rate were observed in both phytophysiognomies. Species richness and individual density<br/>have been diversified over time. Floristic changes were more intense in CD, with significant alterations between<br/>mortality and recruitment rates – the species that disappeared were represented by a few individuals; in the CSS,<br/>the changes were not significant.<br/><br/>Keywords: conservation, disturbances, diversity dynamics.
