The Atlantic Forest, in the state of Bahia, Brazil, is a fragmented hotspot that faces challenges in order to overcome environmental degradation. Ecological connectivity is one strategy that may mitigate environmental impacts. The objective of the study was to develop a spatial proposal for an ecological corridor between the forest fragment of the UFSB Sosigenes Costa University Campus, the private Natural Heritage Reserve Estação Veracel and the Pau Brasil National Park, as well as understand the mechanisms for the implementation of an ecological corridor that involves different government sectors in possible public-private support strategies. The topographic, socioeconomic, ecological and legal characteristics were evaluated in a geographic information system. Using the minimum cost method, the potential areas were modeled for a spatial mapping of connectivity between the areas. The proposed corridor has a length of 9.78 km, a width of 978.70 m and a total area of 942.70 ha. Due to a predominance of anthropogenic activities, mitigation strategies would be required for its implementation. Public-private partnerships can promote forest connectivity and mitigate threats to the stability of local ecosystems, inside and outside of conservation units, and permanent preservation areas should be prioritized as a source of forest connectivity.

Brazilian protected areas are subjected to an intense process of fragmentation due to the lack of environmental regularization and anthropic activities inside them. This study evaluates the forest fragmentation of the Alto Cariri National Park inside the Atlantic Forest of northeastern Brazil. The mapping of forest fragments was performed with the visual interpretation of a satellite image, analyzed based on landscape metrics and physical and topographic conditions. The results show a high forest fragmentation, which is responsible for the segmentation of the forest patch into 120 fragments, predominantly smaller than 5 ha, with an irregular shape and incident edge effect. The obstacles to the preservation of the Atlantic Forest are due to the irregular use of these areas for the production of cattle in pastures and the lack of agility of the public power to implement the expropriation of the population, the drafting of a management plan and decision make.
