Abstract

Conservation Units (UC) are areas with relevant natural features, with limits defined and with the goal of protecting and preserving nature, being admitted only the indirect use of its natural resources, which should reconcile nature conservation with the use sustainable portion of their natural resources. The areas around the UC are strategic to the protection of biodiversity and the local sustainable development of the population. However, it is necessary that there are restrictions and limits on the use and occupation of land in the surroundings, to reduce the influence of negative impacts on biodiversity in protected areas. The aim of this study is to provide a technical foundation for the determination of criteria that define the extent, use and occupancy of the buffer zone (BZ) of the Alto Ribeira Tourist State Park (PETAR). To this were developed criteria that define: a) the extent of the buffer zone and b) the use of the buffer zone. The definition of the extent of the buffer zone PETAR was based on the delineation of watersheds whose rivers drain into the park and approximation of the antropic vectors to the park boundary. The criteria that defined the use and occupancy of the landscape in the buffer zone were based on the vulnerability to soil erosion. It is concluded that the buffer zone of 10 km covers the criteria used here, covering the source of watersheds and large forest fragments. However the quality of the park is threatened by expanding agriculture, mining, illegal harvesting for palm-heart and forestry. The expansion of these activities occurs irregularly in areas of high vulnerability to erosion and can endanger the maintenance of the quality of the biome protected. (AU)
