AVALIAÇÃO DOS INDICADORES DE DESENVOLVIMENTO DA VEGETAÇÃO EM ÃREAS EM RECUPERAÇÃO

Abstract

Mining activities imply in vegetation destruction and, in many cases, the superficial layer of the soil is also removed, therefore the remaining soil is destroyed by eroding processes. Thus, recovery actions such as reforestation are legally required. This study was accomplished at Poço farm (Jacarei/SP/Brazil) that in the past (1970-1990) showed companies of sand’s extraction in part of its area. The aim of this study was to evaluate the development indicators of vegetation in order to verify the effectiveness of recovery actions taken by FVE (Proc. SMA 73.266/98) in two areas with different managements: direct tillage and introduction of top soil.
