Edaphic Filters and Plant Colonization in a Mine Revegetated with Sewage Sludge

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 revege...
