Brazilian karst areas are regions of high biological, geological, and human value that provide ecosystem services, such as aquifers and minerals. Despite the existence of environmental laws, karst areas are still poorly studied and poorly protected in Brazil. This study proposes a spatial prioritization for the conservation of these areas based on indicators of anthropogenic impact, the network of conservation units, and natural vegetation cover. The results show that most Brazilian karst regions are under strong anthropogenic impact, with low natural vegetation cover and little protection by legislation. The need to include karst “spots” in public policies, especially in the creation of conservation units was highlighted. In addition, it is reinforced that the sustainable use of resources in these regions, even if highly exploited, is the only viable solution to ensure the continuity of economic activities, the existence of healthy ecosystems, and the maintenance of ecosystem services.
