30 Years of Atlantic Forest Restoration: Successes, Challenges, and the Future

For over 30 years, significant efforts have been made to restore the Brazilian Atlantic Forest, a biodiversity hotspot facing immense pressure. This review analyzes the successes, challenges, and emerging trends in these restoration initiatives. Our findings reveal a shift from past practices that often failed to establish self-sustaining ecosystems. Today, restoration projects prioritize the creation of resilient, self-perpetuating forests that support rich biodiversity. We found that reconstructing diverse and permanent forest cover is achievable, though contingent on the strategies employed and the surrounding landscape. While innovative techniques like seed rain management and natural regeneration are being explored, planting diverse native species remains the dominant approach in the Atlantic Forest, demonstrating effectiveness even in heavily disturbed areas. Currently, ambitious projects aim to restore thousands of hectares of forest, integrating cutting-edge techniques. However, significant challenges remain in making restoration an efficient and scalable solution for Atlantic Forest conservation. These challenges include: * Reducing costs: Making large-scale restoration financially viable is crucial. * Landscape-level planning: Integrating restoration efforts across landscapes to maximize ecological benefits is essential. * Addressing socio-political barriers: Effective restoration requires navigating complex social and political landscapes. Developing and implementing socio-political mechanisms to overcome these barriers is paramount. This review provides valuable insights for researchers, practitioners, and policymakers engaged in the critical mission of restoring the Atlantic Forest.
