Site description Grand Manan Island is a large, often foggy, island situated on the western side of the mouth of the Bay of Fundy. This IBA encompasses: a ten kilometre band of open water around the island, Old Proprietor Shoals, all the smaller islands in the archipelago, and a one kilometre strip of coastal land along Grand Manan Island. The 10 km strip may be more than is necessary to encompass important bird use, especially on the west side, but has been used here due to insufficient knowledge of pelagic bird use. Old Proprietor Shoals are found off the southeastern side of the archipelago, as are other relatively shallow waters. The northern and western sides of the island are bordered by high cliffs, while the eastern shores are composed of boulders, cobbles and a few sand beaches. Many of the smaller islands in the archipelago are rocky, but Grand Manan Island itself is a diverse mix of wetland and forested habitats.
