Critical Habitat Descriptions in the Canada Gazette

Description of critical habitat of the Red Knot (Calidris canutus rufa subspecies) in Wapusk National Park of Canada

The Red Knot (Calidris canutus) is a shorebird protected under the Migratory Birds Convention Act, 1994. The Calidris canutus rufa subspecies (hereafter rufa) is listed on Schedule 1 of the Species at Risk Act. The habitat needs of Red Knots in Canada are similar across the subspecies and include stopover sites consisting of coastal marine, estuarine habitats and inland saline lakes used during migration. Red Knots also require dry, slightly elevated, tundra that is free from snow cover for nesting. Rufa is known to occur in all of Canada, except the Yukon, and unlike other Red Knots, breeds solely in Canada.
