Site description Shepody Bay is a large tidal embayment at the western head of the Bay of Fundy. It, along with the rest of the Bay of Fundy, has the highest tides in the world (up to 16 m). It contains vast areas of intertidal mud flats such as Daniels Flats, which extend up to 4 km seaward. A narrow band of salt marsh, which was drained and is now used for haying, lies adjacent to the flats. Sand and gravel beaches stretch for 107 ha to the north of Marys Point, a finger of land that separates Shepody Bay and Chignecto Bay further south. To the south of Marys Point are 940 ha of intertidal mud flats, called the New Horton flats. The Shepody Bay National Wildlife Area (which includes a freshwater marsh), Daniels Flats, Marys Point and the New Horton flats are all included in this site, along with Grindstone Island, and Cape Enragé, a major headland to the south, which juts into Chignecto Bay.
