Approximately 0.6% of the Federal District in Brazil is degraded by mining. To indicate native woody species for revegetation works, a floristic survey was carried out in abandoned mined sites. Seventy- eight native and 14 exotic cerrado species were found on the sites. However, only eight species showed to be constant in such environment (frequency > 50%).Eighteen other species presented frequencies between 25 and 50% and the remaining 74% were considered accidental to mined areas left to primary succession (frequency < 25%). Trees made up to 65% of native species and pioneer species contributed to over 70% species richness. Based on frequency and abundance values, the eight constant-species (frequency > 50%) plus the eighteen accessory-species (frequencies between 25 and 50%), which account for 78.9% of the woody-layer abundance, can be indicated for revegetation works of mined areas in the Brazilian cerrado.
