A vast wetland complex (Canada's second largest Ramsar site), embracing a series of beach ridges interspersed with ponds, bogs, fens and marshes subject to salt water inundation that includes the worlds most southerly example of tundra ecosystem. The area regularly supports hundreds of thousands of important populations of Anatidae (ducks, geese, swans, etc.), a breeding colony of more than 50,000, and during migration more than one million geese (Anser C. caerulescens). During migration the lowlands support a substantial proportion of the central Arctic breeding population of Calidris canutus and the entire breeding population of Limosa fedoa. Numerous species of large mammals are present. Ramsar site no. 360. Most recent RIS information: 2001.
