Legal norms and market behavior demand a new posture when facing the environment of various economical factors. In the forest sector, this posture has been defined through the restructuring of the use and occupation of cultivated areas with commercial forests, promoting the environmental compliance of productive activities. This reorganization of rural areas, and areas of permanent preservation and legal reserves which were improperly occupied by forest activities, and thus opposing current legislation, are being restored in order to promote reoccupation using native arboreal species. The SilvSust project has acted in the evaluation of environmental factors in an estate which practices Eucalyptus spp. forest culture, belonging to the firm called International Paper of Brazil, in the county of Brotas, SP. The use of GIS (Geographic Information Systems) and Remote Sensing Images have made it possible to map the different environments which suffered modification, and has thus created more adequate alternatives in the use of lands under the environmental standpoint. The project's goal was to evaluate the current state of bush-arboreal flora and fauna biodiversity in the mentioned estate, in order to define indicative values which reflect the sustainability of these lands, and the methods used to evaluate these indicators, and make it possible to apply them in other rural estates which are part of the silviculture production sector. The study also aims to generate data to qualify the use of Eucalyptus spp. in reforestation of areas which are destined to restore legal reserves in the state of São Paulo , in accordance with the law #12,927 of 2008, and the decree #53,939 of 2009, allowing the compensation of legal reserves by means of planting exotic arboreal species interposed with native ones. With this work, the hope was to build scenarios reflecting the dynamics in the use and covering of lands, all in accordance with sustainability indicators which reflect the silviculture sector's productive chain, as well as these indicators' evaluation methods.
