Establishing forest protection standards is essential for biodiversity conservation and for ensuring the public water supply. This study evaluated whether compliance with environmental legislation aimed at protecting the Atlantic Forest is sufficient to minimize the negative effects of urban pressure on the conservation of biodiversity in the water source area of the Billings reservoir in the municipality of Diadema. To assess the effectiveness of environmental legislation, we created a current land use and land cover map as well as maps for an expected legal scenario and evaluated both using landscape metrics. Our findings indicate that forest resource availability in the area is critical but can be improved by compliance with legal obligations, which have complementary effects and the potential to promote less fragmented landscapes. On the other hand, they do not prevent the tendency of fragmentation caused by the surrounding urban matrix, which can reduce the positive effect of the legal compliance on forest conservation in cases of consolidated urban areas.
