Birdlife International has launched the Neotropical Mangrove Conservation Alliance, also known simply as the Mangrove Alliance, as an online resource to foster the preservation of endangered mangrove habitats. Supported by MacArthur, the Alliance will help to coordinate mangrove conservation activities at priority sites in the Caribbean islands. Since 1980, mangroves like those in the Caribbean have shrunk to just 23 percent of their former range and 11 different species of mangroves are considered threatened. The Mangrove Alliance will help build opportunities for collaboration in preservation by allowing for experience sharing, networking, capacity building, and further partnership development between Birdlife and other organizations. Birdlife is the world’s largest partnership of conservation organizations and strives to conserve birds, their habitats like mangroves, and global biodiversity.
