Welcome to the world of wetlands…... Prepare to be amazed!

Canadian Prairie Potholes Canada possesses more than 25% of the world’s wetlands. Scientists estimate that more than 50% of all the ducks in North America rely on the prairie potholes for survival An estimated 60% of the wetlands in the Parkland region alone have disappeared

MarshSwamp Bog Fen
6
Boreal Sedge Fen
7
Marsh non-peat wetland emergent reeds, rushes or cattails highly productive deep open water zones provide spawning grounds for fish feeding and gathering areas for migrating waterfowl
8
Swamp non-peat wetland dominated by trees or tall shrub thickets soft maples, cedar, alder, willow provide habitat for cavity nesting birds - mergansers, wood ducks
9
Bog northern, peat wetland primarily from runoff and rainfall, very acidic low productivity sphagnum moss, black spruce, tamarack Bogs are the oldest wetlands
10
Fen peat wetland formed from groundwater & runoff slightly acidic or alkaline slightly higher productivity then a bog dominated by sedges contains rare wildflowers and orchids
11
Sphagnum Moss Cells are filled with gas Holds 200 times its own weight in water Sinks with age forming peat Layer grows 3-7 cm in a century!

In a marsh you will find three varieties of aquatic plants: 1) Emergent 2) Submergent 3) Floating
15
Other fabulous floaters include: Common Bladderwort Common Duck Weed Free-floating, non-rooting Bladders serve as reservoirs Bladders trap tiny invertebrates Rapid reproduction Used to treat sewage and wastewater Used to feed fish and other livestock
16
Other entertaining emergents: Common Butterwort Resembles violet Found in calcium rich soil Insect-eating perennial Yellow Marsh-Marigold All parts contain poisons Poultice of leaves to treat warts Leaves can cause skin to blister
17
Another super submergent: Clasping-leaf Pondweed Perennial Flowers in dense staked spike An important food source Provides shelter for aquatic invertebrates

Purple Loosestrife European invasive species No nutritional value for native wildlife 190 000 hectares affected each year Biological controls are being researched
