Abstract

In this study we describe a case study to evaluate the floristic diversity and the soil conditions of post mined area, currently under 14-years of restoration. The study area is located in the municipality of Descoberto, Minas Gerais State, Brazil, and has one hectare in the process of restoration through the planting of seedlings. The forest inventory of all individuals with Circumference at Breast Height (CBH) ≥15 cm was carried out and the phytosociological parameters were evaluated. The study area shows a high floristic diversity H′ = 3.258 as well as equability (J′ = 0.783), evidencing that the study area is floristically heterogeneous and has low ecological dominance. In addition, this area presented floristic similarity to other restored areas that were already in a more advanced restoration process. Considering soil quality, the restored study area shows higher levels of cation exchange capacity (t), approximate sum base values (SB) and base saturation (V) than those verified in nearby areas. Evaluating the successional characteristics (greater presence of individuals of secondary succession) and the domain of species with dispersion by animals, we can infer that the area is in an advanced stage of restoration, as well as performing its environmental and social functions. Thus, we can conclude that the restoration of mined areas is feasible when the restoration techniques are applied correctly. Furthermore, we can say that these successful restoration measures are improving the environmental sustainability and helping considerably the recovery of losses caused by mining.
