The objective of this work was to study species that can be tested in the recovery of Arsenio
high concentration areas. Therefore, 10 cerrado areas degraded by gold exploration in Paracatu-MG, Brazil
were studied. It was used the Braun-Blanquet cover value and abundance scale. The species were classified
by the Raunkiaer life form. The areas were floristically compared by Sørensen index. Out of 197 woody and
herbs morpho-species found, 102 were identified at specific level, 35 at genus level and 40 at family level.
Twenty morpho-species could not be identified. There was a great floristic richness among sample units
(21-53 species), which influenced the formation of three groups in floristic similarity analysis. The more abundant
and probably more adapted species to the environmental conditions were Axonopus marginatus, Simarouba
amara, Aristida ekmaniana, Digitaria ciliaris, Stylosanthes viscosa, Andropogon bicornis, Maprounea guianensis
and Sabicia brasiliensis. The most frequent form of life was phanerophyte followed by hemicryptophyte and
chamephyte. In the biological spectra, it was possible to visualize the different structure of the studied areas,
emphasizing the environmental diversity present despite presenting low floristic richness.
