Abstract: Post-fi re response by vegetation may refl ect the severity of the damage suff ered, but we still know little about the species-specifi c nature of responses to fi re or their predictors. Here, we evaluated 26 woody species before and after a fi re event in an Cerrado sensu stricto area (typical Brazilian savanna-type) in order to evaluate mortality rates and the type of resprouting (epigeal, hypogeal or epigeal + hypogeal). We evaluated the relative importance of stem diameter, height, and bark thickness as predictors of the type of post-fi re resprouting, using a sequential logistic regression model (SLRM). Mortality was 4 %, while epigeal resprouting was recorded in 57 % of the individuals, hypogeal resprouting was recorded in 24 %, and epigeal + hypogeal resprouting in 15 %. Our SLRM analysis indicated that bark thickness, followed by stem diameter, were the best predictors of the type of resprouting. Th ere was a greater than 60 % probability that individuals with bark thicker than 1.6 cm resprouted only epigeally. Our results confi rm the resistance (low mortality) and resilience (high resprouting capacity) of the woody vegetation of the Cerrado sensu stricto to fi re, and that thick bark is an eff ective protection against fi re damage.
