Charitable registration # 10686 8755 RR0001, // , Filled by waters from surrounding streams, rivers, lakes and melted snow, Key reservoir areas in spring and summer take in water to help prevent flooding in spring and release it in summer should the water table drop, preventing drought, Nutrient-rich environment that supports dense plant life, in turn attracting a variety of animal species, In northern swamps, white spruce, black spruce and sometimes cedar, Farther south, red maple, ash and some birch species, Even farther south, silver maple, blueberries, ferns and skunk cabbage, Swampy thickets composed of shrubs such as willow, alder, buttonbush and red osier dogwood, Provide habitat and resources for salamanders, frogs, ducks, hawks, owls, coyotes, snowshoe hares and black bears, Important overwintering areas for deer, which often choose areas thick with coniferous trees where they browse for winter food, Water comes from underground springs, rainfall, run-off and melted snow, Filters out silt, helping to keep and lakes and waterways clean, Sometimes dries up entirely but can re-establish itself with seeds left behind from the previous season when moisture returns, Can be knee height or up to two metres deep, , with abundant vegetation; supports a lot of creatures, Considered one of the most productive ecosystems, important for species diversity, Contains plants like cattails, pickerel weed, arrowheads, pond lilies and coontails, Specialized plants in saltwater marshes can withstand salty conditions; some deal with temperature fluctuations as the tide moves in and out twice daily, Important areas for muskrats, minks, beavers, otters, turtles, frogs, waterfowl and other birds like kingfishers and osprey, Muskrats form series of channels that help create habitat for ducks, bitterns and other marsh animals, Shallow, warm waters used as spawning grounds for muskellunge, largemouth bass, minnow species and sunfish—important for freshwater fisheries, Migrating waterfowl like blue-winged teal and ring-necked ducks use marshes for gathering and feeding in autumn. Small action or big project, every little bit helps and Wetland Heroes can be individuals, classes, schools, or community youth clubs. [CDATA[ Large construction projects and some logging operations can dump huge amounts of sediment into lakes and rivers. A wetland is any area of land that is covered with water for at least part of the year. Sadly, wetlands are often wiped out or modified to make way for farmland and housing developments. Plants and animals living in a marsh break down sewage and many chemicals, leaving clean soil and water behind. Some do so on a permanent basis, while others only inhabit them during a small portion of the year. These places where water and dry land meet are home to a wide range of species, from dragonflies and damselflies, to wading curlew and snipe; from carnivorous plants to flitting butterflies. The specific species of animals that are found in wetlands are determined by the wetland's location. Mostly found in Arctic and Subarctic regions, though older wetlands, which are more vulnerable to disturbances and change, are also found in areas farther south. A wetland is simply any area of land that is covered with water for a part of the day or year. 21 in the Ecological Land Classification Series. Canada's Wetland Animals could be used by teachers with the entire class in studying nonfiction, as a book for student research, or as a nonfiction book for students to read for pleasure and information. ... As a part of an on-going partnership with ECCC, we invest funds from the Canadian Wildlife Habitat Conservation Stamp to protect and conserve wetlands and waterfowl. ga('linker:autoLink', ['', ''] ); Oil spills in particular can kill huge numbers of fish, birds, shellfish, and plants. Additionally, billions of dollars are earned annually through agriculture, fishing, mining, manufacturing, and power-generation.As for water's more indulgent benefits, consider the value of canoeing silently through the reeds on a misty spring morning, or the sight of Canada geese splash-landing on a marsh during a crisp fall sunset. ga('linker:autoLink', ['', ''] ); Drying Canadian wetland drives muskrat decline. Just to be clear: You can conserve wetlands. Wetlands are land that is temporarily or permanently covered with shallow water. ga('create', 'UA-3780889-1', 'auto', {'allowLinker': true}); On the other hand, many of our frogs, toads, and tree frogs breed in temporary ponds and marshes but spend much of their adult life on the surrounding dry land. History, politics, arts, science & more: the Canadian Encyclopedia is your reference on Canada. As a resource, the CWI is valuable for a number of other purposes. Only habitat for unique wildflower species like sundews and pitcher plants, which are adapted to a nutrient-poor, acidic environment; these plants are carnivorous and obtain some nutrition from trapped insects, Tamarack and spruce sometimes found in or around bogs but are very slow growing, Other bog plants include shrub willows, cotton grass, Labrador tea, bog cranberry and mosses, Habitat for weasels, foxes, fishers, lynx, red squirrels and other small mammals, as well as hawks, owls and many song birds, Found mainly in the North, though also found farther south, Some water movement; not completely stagnant, Water is slow moving and may dry out in summer, Water table hovers around peat’s surface or just above it, Peat is usually 40 centimetres thick or less, Not very productive wetlands, but do receive nutrients from streams, run-off and groundwater, making them more nutrient rich than bogs, Can range from a productive area with lots of nutrients, plants and wildlife to a less productive area that is nutrient poor and has low species diversity, pH is greater than five and is either somewhat acidic or somewhat basic, are dominant; mosses, grasses and reeds also found, If trees are present, they are usually tamarack, cedar, spruce or dwarf birches, Hawks, nesting waterfowl and other birds, amphibians, small mammals like voles and jumping mice and large mammals like mule deer and caribou, Receives water from run-off, precipitation, groundwater and other water bodies, Transitional area between lakes and marsh areas, Unchanging temperature from top to bottom, unlike lakes which are stratified, Variable; can be quite productive in nutrient-rich areas, Some milfoils, sedges, water lilies, water hyacinth and duck weed, Supports crustaceans, fish, amphibians, waterfowl and reptiles, Moose and beaver may use peripheral areas. Wetlands include, among other waterlogged wonders, swamps, fens, marshes, muskeg, peatbogs, and potholes. Fig. They provide hundreds of species with safe places to eat, sleep and raise young. Ordinary cattails and bulrushes, for instance, can absorb poisonous heavy metals like lead and mercury. Be extra careful—what may feel and appear to be a solid floating sphagnum mat may not fully support your weight. Wetlands are the whole world for many salamanders, snakes, turtles, and aquatic insects. Many animals live within wetlands. This process is called eutrophication.• Wastes dumped into water from paper mills or treatment plants are also eaten by bacteria.
