Resumo: | This study aimed to evaluate the formation of functional groups, in 1994 and 2012, in two areas of savanna with different fire history in Planaltina, Federal District, Brazil. In the Area 1 biennial burnings were applied in August 1988, 1990 and 1992; there was fire protection until July 1994 in the Area 2, the control area. Accidental fire occurred in both areas in August 1994, but from September 1994 to 2012 they were protected. These analysis included individuals with abundance ≥ 5 using the unweighted pair group method with arithmetic mean (UPGMA). The groups were defined according to the following attributes: dispersal and pollination syndromes, leaf phenology, life form, type of bark and ability to sprouting after fire. Both areas presented differences in the formation of functional groups in 1994 and 2012. Species functionally similar and with lower diversity of attributes were observed in Area 1, in 1994. The exclusion of fire favored the recruitment of other species and greater diversity of functional attributes in 2012.
