" In the summer of 2007 an enormous wild fire occurred on Vidlič Mt. (Southeast Serbia), whichburned down more than 2500 ha of vegetation. Our aim was to study the short-term patterns of diversity changes and vegetation dynamics in the grasslands and rocky groundvegetation affected by the fire. Plotsof vegetation were observed according to Braun-Blanquet phytosociological methods. Species richnessand Simpson’s diversity index were calculated per quadrant for each of three seasons. ANOVA, UnequalHSD post hoc test and Linear Regression were performed in order to follow the post-fire vegetationdynamics and diversity. The species richness and diversity of the fire-affected sites were highest in thezone of thermophilous oak forests, slightly lower in the transitional belt, and lowest in the belt of beechforests. With increasing altitude, the values of richness and diversity decreased. Considering life-formscomposition, the most important influence of wildfire was the relationship between two most represented categories, hemicryptophytes and therophytes. It was concluded that the cover values of 13 species showcomparatively high levels of statistically significant differences between the stages of vegetation formed in the post-fire period. Limestone grasslands and rocky ground vegetation showed quick recovery afterthe fire, which indicates that these habitats show comparatively high resilience to fire. "
