ABSTRACT

We evaluated the recruitment of plant species and their relation with edaphic attributes in a mine
revegetated with sewage sludge in the Brazilian Federal District. Plant species in the revegetated
mine and in remaining portions of Cerrado (savanna) within the mined landscape were sampled
and identified. Then, samples of revegetated substrate and soils from Cerrado portions were
collected, analyzed for chemical attributes and submitted to statistical tests. Results indicated that
the remaining portions of Cerrado were colonized by 91 species (22% allochthonous species),
and the revegetated substrate housed 62 species (55% allochthonous species). Multivariate tests
showed that the edaphic condition built from the incorporation of sewage sludge into the mining
substrate acted as filter on the assemblage of plant species. Despite the two study sites shared the
same landscape, the Cerrado portions and the revegetated substrate did not share similar plant
communities after a decade from mine rehabilitation works.
