Izembek National Wildlife Refuge lies between the highly productive waters of the Bering Sea and the Gulf of Alaska. Within the heart of the Refuge is Izembek Lagoon, a 30-mile long and 5-mile wide coastal ecosystem that contains one of the world's largest eelgrass (Zostera marina) beds. More than 200 species of wildlife and nine species of fish can be found on the Refuge. Millions of migratory waterfowl and shorebirds find food and shelter in the coastal lagoons and freshwater wetlands on their way to and from their subarctic and arctic breeding grounds. This extraordinary abundance and diversity of waterfowl has attracted international attention. In 1986, Izembek National Wildlife Refuge and Izembek State Game Refuge, which encompasses the submerged land of Izembek Lagoon, was the first wetland area in the United States to be recognized as a Wetland of International Importance by the RAMSAR Convention. In 2001, Izembek Refuge was also designated as a Globally Important Bird Area by the American Bird Conservancy.
