Site description The Shagamu River enters Hudson Bay about half way between the Severn River to the west and the Winisk River to the east. The site encompasses both sides of the mouth of the Shagamu River for about 40 km east to Ministick Creek and 30 km west to Beavertrap Creek. Numerous beach ridges are located parallel to the coast, with hollows containing thousands of small ponds and lakes. Near the coast, supertidal marshes occur inland, with extensive intertidal marshes and submerged shoals extending well offshore. The raised beach ridges are vegetated with scattered graminoids, and these ridges becoming covered with heath tundra and scattered spruces as one progresses inland. These coastal beach ridges are an important calving area for Woodland Caribou (designated as nationally vulnerable).
