Restoration of the Grande-Ferme and Des Graves managed marshes of the Cap-Tourmente National Wildlife Area

The Cap Tourmente National Wildlife Area (CTNWA) is located on the north shore of the St. Lawrence River, 50 km northeast of downtown Quebec City. The CTNWA includes several managed marshes. The proposed project concerns the Grande-Ferme (lot 3 814 431) and Des Graves (lot 3 815 308) marshes. These marshes were developed in 1982 and 1996 respectively by Ducks Unlimited Canada (DUC), in collaboration with the Canadian Wildlife Service (CWS) of Environment and Climate Change Canada (ECCC). These permanent marshes were designed to provide habitat for local and migratory wildlife such as waterfowl. The work consisted of the installation of dikes and water level control structures, creating marshes of 3.9 ha (39,000 m2) for the Grande-Ferme marsh and 5.0 ha (50,000 m2) for the Des Graves marsh. Due to the age of the structures, rehabilitation work is required to ensure the protection of the environment. This work is essential and will have to be carried out in the near future to ensure the maintenance of ecological functions and biodiversity and to conserve the habitats of the species found there.
