Challenges and Opportunities for Biodiversity Conservation in the Brazilian Atlantic Forest

TLDR

The Atlantic Forest, a biodiversity hotspot with over 8,000 endemic species, now covers only about 7 % of its original area and is fragmented into isolated patches threatened by habitat loss, logging, hunting, and invasive species. The study proposes a comprehensive strategy that integrates regulations, public policies, incentives, and existing conservation projects to establish sustainable landscape networks and halt deforestation and species loss. Despite an increase in conservation initiatives, more than 530 plant and animal species are officially threatened, many lacking protection, indicating that current efforts are still inadequate to safeguard the forest’s biodiversity.

Abstract

Abstract: With endangered status and more than 8,000 endemic species, the Atlantic Forest is one of the world's 25 biodiversity hotspots. Less than 100,000 km 2 (about 7%) of the forest remains. In some areas of endemism, all that is left are immense archipelagos of tiny and widely separated forest fragments. In addition to habitat loss, other threats contributing to forest degradation include the harvesting of firewood, illegal logging, hunting, plant collecting, and invasion by alien species—all despite the legislation that exists for the forest's protection. More than 530 plants and animals occurring in the forest are now officially threatened, some at the biome level, some throughout Brazil, and some globally. Many species have not been recorded in any protected areas, indicating the need to rationalize and expand the parks system. Although conservation initiatives have increased in number and scale during the last two decades, they are still insufficient to guarantee the conservation of Atlantic Forest biodiversity. To avoid further deforestation and massive species loss in the Brazilian Atlantic Forest, the challenge is to integrate the diverse regulations, public policies, new opportunities, and incentive mechanisms for forest protection and restoration and the various independent projects and programs carried out by governments and nongovernmental organizations into a single and comprehensive strategy for establishing networks of sustainable landscapes throughout the region.
