Coastal wetlands are valued for their diversity of wildlife, habitats, and functions. The Canadian Wildlife Service (CWS) conducted vegetation and elevation surveys between 2009 and 2019, and bathymetric and light attenuation surveys between 2018 and 2019 in coastal wetlands across the Canadian...

The national wetland layer contains wetland data compiled from the best available data from each region, classified by wetland type. Wetlands are mapped as polygons in geographic layers, which are integrated into a master geodatabase at the national scale.Information from each contributing...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Extent of Canada's wetlands indicator is a measure of the extent of Canadian wetlands, and provides a baseline from which...

The subjects of this study – the St. Lawrence (river, estuary and gulf) and the Ottawa and Richelieu rivers – present a range of natural shoreline habitats that are conducive to the flourishing of avian, aquatic and terrestrial fauna. Avian fauna, particularly migratory birds, use wetlands as...
