The Importance of Sampling Anthropized Areas of Atlantic Forest for New Records of Woody Species1 (Scientific Note)

Abstract

Phytosociological studies are important for the knowledge of biodiversity patterns and help to elucidate of distribution and abundance of species. We aimed to quantify the wood component in areas that had evident anthropic impacts and presence of exotic and invasive species in Ilha Grande, Rio de Janeiro State, Brazil. The shrubby-tree component with Diameter at Breast Height - DBH ≥ 5cm was quantifed by means of 16 circular plots with 15m radius, of which eight with presence of invasive species Artocarpus heterophyllus Lam. Were identifed 19 new occurrences for Ilha Grande-RJ and two endemic species to the Rio de Janeiro State. We concluded the necessity of quantitative studies in anthropized areas, because these also can conserve biodiversity and are neglected in foristic and phytosociological studies.
