The Sargasso Sea is named for the Sargassum seaweed that creates its unique ecosystem. It is a haven of biodiversity and there is growing recognition of the crucial role it plays in the wider North Atlantic ecosystem as habitat, foraging and spawning grounds and as a migratory corridor. Endangered European and American eels migrate to the Sargasso to breed. Wahoo, tuna and other pelagic fish forag
e in and migrate through the Sea, as do a number of whale species, notably sperm whales and humpbacks. The Sargasso Sea supports a range of endemic species and plays a critical role in supporting the life cycle of a number of threatened and endangered species such as the Porbeagle shark, the American and the European eel, as well as billfish, tuna and several species of turtle, migratory birds and cetaceans.The Sargassum mats are home to many endemic species and provide a protective ‘nursery’ for juvenile fish and turtles. There is emerging recognition of the crucial role it plays in the wider ecosystem ranging from the Atlantic to the Caribbean and the Gulf of Mexico. The Sargasso Sea Commission was established pursuant to the Hamilton Declaration on Collaboration for the Conservation of the Sargasso Sea, signed on 11 March 2014, by the governments of the Azores, Bermuda, Monaco, UK and US. The Commission will “encourage and facilitate voluntary collaboration toward the conservation of the Sargasso Sea.” While the Commission has no management authority, it will “exercise a stewardship role for the Sargasso Sea and keep its health, productivity and resilience under continual review.” A more specific initial mandate is listed in Annex II of the Declaration. The Commission is the result of three years of work by the Sargasso Sea Alliance, and operates as a stand-alone legal entity established by Bermudian and US law. Operating in a largely virtual setting, Commissioners will serve in-kind in their personal capacity and will be supported by a small Secretariat based at the IUCN Washington, DC office. Commissioners were appointed by the Government of Bermuda and were selected through a consultation process in Spring 2014 by governments who support the aims of the Hamilton Declaration.
