The woody vegetation of the Cerrado presents adaptive properties to the fire. The fires during the dry season may cause significant changes in the structure and floristic composition of the vegetation. This study aimed to evaluate the flammability of six native species of a Cerrado fragment located in southern Tocantins. Samples composed of fine materials of the selected species were collected, with a diameter of less than 7 mm, excluding young leaves and apical buds. For each species, 50 repetitions were performed, being analyzed: ignition frequency, ignition time, combustion duration, combustion index, and the determination of flammability value. Among the evaluated species, Curatella americana L., Clethra scabra Pers. and Anacardium occidentale L. Obtained significant values with emphasis on Clethra scabra Pers. Which obtained the highest mean values of the flammability variables. We also observed that most species had a combustion index classified as very high (CI = 4 and CI = 5). With this study we can conclude that most species are flammable, and Clethra scabra Pers. Was the species that presented the best result of the flammability variables being classified as highly flammable. On the other hand, Macrolobium limbatum Spruce ex Benth. var. limbatum and Ziziphus Cinnamomum Triana & Planch. Were the species that obtained the lowest results being classified as weakly flammable.
