Análise fitossociológica do estrato arbóreo de uma cascalheira revegetada no Distrito Federal

Abstract

Four decades of human settlement and urbanization resulted in the deforestation of 57% of the native vegetation in the Brazilian Federal District. In this regard, mining activities degraded 0.6% of the territory, and revegetation works have been carried out on some mined areas. This work aimed to evaluate the tree community established on the ninth largest mined area in the Federal District under the criteria of resolutions SMA 21/2001 and SMA 47/2003. A floristic survey on the site could identify 62 species (57 native and 5 exotic species) from 49 genera and 25 families. Tree community on the site has complied with four out six criteria evaluated: high species diversity, limits of abundance per species, the use of at least 50% local species and a succession revegetation model attended the resolutions. The Project did not comply with the use of at least 10% endangered species and at least eighty different species.
