Wetlands: What are they?
2
Wetlands Wetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year, or at different times during the year. Have soil that is “hydric,” or that can hold water (High clay content or low permeability) Have “wetland” plants and animals. (Permeable= the ease with which water passes through a porous material)

Marsh
4
Wetland Types MARSHES- have standing water from less than an inch to several feet deep; usually shallow with few floating plants. Plants: cattails, grasses, sedges, rushes, arrowhead, pickerel weed, and smartweed; critical for many fish species that live and/or breed there. Marshes offer primary breeding and feeding habitat for water birds (ducks, geese, herons, cranes, rails) and song birds like the marsh wren and yellow warbler, numerous frog species, reptiles (turtles, water snakes), and mammals such as muskrats, beaver, and otter. In Michigan, marshes are found at the edge of some rivers and lakes. They are a transition between land and water.

Swamps
7
Swamps A swamp is any wetland dominated by trees.
characterized by saturated soils during the growing season, and standing water during certain times of the year. serve vital roles in flood protection and nutrient removal. Examples of plant life includes cypress trees, red maples, buttonbush or alder shrub Animals may include wood ducks, river otters, cottonmouth snakes
8
Bogs
9
Bogs characterized by spongy peat deposits, acidic waters, and a floor covered by a thick carpet of sphagnum moss. High level of organic material; highly acidic serve an important ecological function in preventing downstream flooding by absorbing precipitation bogs support a number of species of plants including Cotton Grass, Cranberry, Blueberry, Pine, Labrador Tea, and Tamarack. Moose, deer, and lynx are a few of the animals that can be found in northern bogs. The Greater Sandhill Crane, the Sora Rail, and the Great Gray Owl depend on bogs for survival.
10
Fens
11
Fens Fens, are peat-forming wetlands that receive nutrients from sources other than precipitation: usually through drainage from surrounding groundwater movement. Fens differ from bogs because they are less acidic and have higher nutrient levels. often covered by grasses, sedges, rushes, and wildflowers
12
Why are wetlands important?
Biologic diversity Flood control Beauty Groundwater recharge Place to fish or hunt Place for migrating waterfowl
13
FILTER AND CLEAN WATER!! Nickname- Kidneys of the water cycle!! Many wetland plants can suck up contamination like a straw: cattails-bullursh-water hyacinths
14
Storm water control Instead of muddy water running directly into the streams and causing sediment problems, muddy water is directed into a wetland area, filtered naturally, then slowly discharged back into the stream.
