The Piping Plover (Charadrius melodus) has long been a species of conservation concern throughout its range (fig. 1). In Canada, two subspecies of Piping Plover are recognized: C. m. melodus in the Atlantic Canada region and C. m. circumcinctus in Ontario and Prairie Canada. Both subspecies are listed as endangered under the Species at Risk Act (Department of Justice Canada, 2002; Committee on the Status of Endangered Wildlife in Canada, 2003). Pursuant to the U.S. Endangered Species Act, the Piping Plover is listed as endangered in the Great Lakes watershed and threatened in the rest of its breeding and winter range (U.S. Fish and Wildlife Service, 1985).
