The sprouting is the typical response of pointers to death of trees as a result of fire, courts, diseases or physiological disorders. The present work aimed to study the regrowth ability of species remaining trees in a Seasonal Forest Semidecidual degraded by fire and assess the importance of resprouting ability in the area of recovery. The fire resulted in the destruction of 12 hectares of native vegetation, with differential levels of degradation. The study focused on the section where the effect of the fire was more severe, with total destruction of the vegetation cover. The area a complete survey of all species showing budding was performed. The diameter (cm) at the base of the bud, using a caliper, and the height (m) of the sprout with the aid of a tape was measured. It was observed that the sprouting capacity varies with the tree species and the size/age of the plant. Mabea fistulifera and Dalbergia nigra showed a higher number of shoots; Anadenanthera macrocarpa and Piptadenia gonoacantha the greatest height and diameter, the first of which also had the highest number of shoots per array; Aegiphila sellowiana showed high potential for regrowth both the stem and the roots. The widespread occurrence of grasses, especially the grass (Melinis minutiflora) represents a physical impediment and reduces the brightness to the by sprouting roots.
