Jobos Bay National Estuarine Research Reserve

Puerto Rico’s Jobos Bay reserve is comprised of nearly 3,000 acres of mangrove forest and wetlands, including the Mar Negro area and Cayo Pájaros, Cayos Barca, and Cayos Caribe—an array of coral reef-fringed mangrove islands at the mouth of the bay. The reserve includes extensive seagrass beds, upland dry forests, and lagoons, and is home to the endangered brown pelican, peregrine falcon, hawksbill turtle, yellow-shouldered blackbird, and the West Indian manatee. Through a combination of research, monitoring, and outreach, reserve staff work to advance the sustainable management of Puerto Rico’s coastal resources and to protect regional watersheds and wetlands.
