Selective felling, Araucaria angustifolia, Ocotea porosaAbstract
Selective cutting and pastures are common activities in the Ombrophilous Mixed Forest, which is part of the Atlantic Rain Forest Biome. Our goal was to relate floristic composition and structure unit with its past use. Adult and juvenile wood species of twelve forest fragments were evaluated in Santa Catarina State. Fragments with less anthropic impacts showed greater richness and diameter range, and lower density and frequency of multiple stems in the adult stratum, although basal area did not differ among fragments. Fragments with higher historical impact showed greater richness and lower density of juvenile stratum. The results showed that human impact on wood species community was so great that even after some decades floristic composition and structure differences remain evident and might remain over a long period.Downloads
