The municipality of Silva Jardim, whose region has a rich biodiversity in both flora and fauna, in its fragmented biome. One of the allies for the conservation process of the biomes are the laws implemented by the Native Vegetation Protection Law because it aims to protect mainly the most fragile areas and of extreme importance for the recovery of the landscape. In this sense, this dissertation aimed to evaluate the conservation potential based on the integration of forest fragment analysis and the Native Vegetation Protection Law (Law 12.651 / 12). For that, the methodology looked at the entire historical occupation process of the county. Specialize Native Vegetation Protection Law through geoprocessing techniques in a GIS environment. Using the principles of landscape ecology, were chosen the landscape metrics to assess fragments in the V-Late software, thus being able to characterize the current scenery. As a result, 33.2 percent of Silva Jardim s total was protected by the Native Vegetation Protection Law. The very small and large fragments were the ones that attracted the most attention in the final analysis, with 45 percent of their areas protected, due to their distribution across the landscape. Finally, when we analyze the efficiency of Native Vegetation Protection Law, we cannot cancel the occupation process, given that the most fragmented areas are within the limits of permanent preservation watercourse sector in flat territories. Therefore, it is necessary to think about education and awareness plans for the conservation of the Atlantic Forest.
