Canada's Wetlands,
Documented in Detail
An independent archive covering marsh ecosystems, waterfowl habitats, and the conservation frameworks that shape how wetland areas are managed across the country.
Recent Articles
Detailed coverage of marsh ecology, waterfowl species biology, and the agreements that govern wetland management in Canada.
Marsh Habitats and Biodiversity in Canada
The physical and biological structure of Canadian marshes — from submerged aquatic beds to sedge meadows — and the species that depend on each layer.
Migratory Waterfowl Species of Canadian Wetlands
Profiles of dabbling ducks, diving ducks, geese, and wading birds that pass through or breed in Canadian wetlands each year.
Wetland Conservation Programs in Canada
The major agreements, federal designations, and private land programs that govern how wetland areas are identified, protected, and restored.
Prairie Potholes: The Duck Factory
The glacially formed depressions of the Canadian Prairies produce more ducks per hectare than any other landscape type on the continent. Scattered across Manitoba, Saskatchewan, and Alberta, these seasonal wetlands are among the most studied — and most threatened — habitats in North American conservation history.
Read About Marsh HabitatsThe Boreal Breeding Zone
Canada's boreal forest holds millions of shallow lakes, river bogs, and forested swamps that function as one of the largest waterfowl breeding areas on Earth. Many species that winter along North America's coasts return each spring to nest in this remote interior.
Read About MigrationHabitat Types at a Glance
Canadian wetlands span a wide range of ecological conditions, from tidal salt marshes on the Bay of Fundy to Arctic coastal plains north of 70°N.
Freshwater Marshes
Shallow, nutrient-rich wetlands dominated by emergent plants. Found across all provinces. Primary breeding habitat for dabbling ducks, red-winged blackbirds, and marsh-nesting raptors.
Prairie Potholes
Glacially formed depressions that hold seasonal water across the interior plains. Variable salinity levels support distinct invertebrate communities that drive waterfowl productivity.
Coastal Tidal Marshes
Salt- and brackish-water marshes along Atlantic, Pacific, and Hudson Bay coastlines. Critical stopover habitat for shorebirds and staging areas for Canada and snow geese.
The North American Waterfowl Management Plan
First signed in 1986 between Canada and the United States, the NAWMP established continental population targets and the habitat benchmarks required to reach them. Over four decades, it has guided billions of dollars in habitat investment across the prairie and boreal zones. Understanding how this framework operates — and where it falls short — is central to any serious look at Canadian waterfowl conservation.
