2: Wetlands are large bodies of water that stay in specific areas for long periods of time.
3: Different common types of wetlands are swamps, marshes, & bogs.
4: PHYSICAL CHARACTERISTICS | Swamps: Wooded wetlands with dense trees.
5: Tidal marsh: There are freshwater, brackish, and salty marshes. Sandy & grassy. | Non-tidal marshes: mostly freshwater, but some are brackish. Usually between a few inches and a few feet deep & can sometimes dry out completely. | Marshes Characteristics | Bogs have spongy peat deposits, acidic waters, and a floor covered by a thick carpet of sphagnum moss.
6: How do they form? | Swamps form when wetlands become dominated by woody plants. | Bogs form when thick mats of vegetation like sphagnum moss and sedges decay in a waterlogged environment.
7: Non-tidal marshes form in the shallow water along the boundaries of lakes, ponds, and rivers. | Tidal marshes form when a wetland becomes very grassy. Can be where a shore would be.

10: What plants & animals live in wetlands? | Swamps have cypress & tupelo trees. Animals that live there are crayfish, shrimp, tadpoles, and insect larvae. Alligators live in swamps too. | Bogs have lots of moss & peat. Frogs, salamanders, newts, hares, otters, & foxes also live here.
11: Tidal marshes have many birds & fish like oysters, mullet, shrimp, and blue crabs. Muskrat, Mink, Red-wing blackbird and the Great blue Herons also live here. | In non-tidal marshes, waterfowl and other small mammals, such as Red-winged Blackbirds, Great Blue Herons, otters, and muskrats live.
12: Wetlands are home to many plants and animals that exist nowhere else on earth. Species of birds & mammals that are hunted usually call wetlands home. A lot of ducks & geese live in marshes & swamps. In the past year, the population of these waterfowl has gone down so now there are restrictions on hunting them in these areas. Some species’ populations have been rising again recently. They keep some water maintained in them moderating flooding from heavy rains & they are also a source of water in drier seasons of the year. The water is pollutant free of any toxic chemicals like metals & pesticides. Also, they control shoreline erosion & are a constant home for fish, birds, etc. | Why are wetlands so important?
13: What is happening to the wetlands? | They are dissapearing due to urbanization & industialization. Wetlands near oceans are dissapearing due to sea level rise around the world (Ex.: New Orleans delta) Animals that call the wetlands home are being hunted also.
14: Effects of disappearing wetlands: Water in wetlands will be lost as a resource for people during droughts. Lots of varying animals found nowhere else on earth will lose their homes in swams, marshes, & bogs. As for places like New Orleans, barriers for hurricanes & such will be lost posing threat for cities.
15: Human activities destroying the wetlands: Development. Agriculture. Silviculture. The U.S. loses 60,000 acres of wetlands per year. Another problem is polluted runoff from the urbanization surrounding wetlands. Examples of these pollutants are sediment, fertilizer, human sewage, animal waste, road salts, pesticides and heavy metals. Plus, domestic animals over-feed on natural vegetation here. | An algae bloom as a result of agricultural runoff.
16: To help save wetlands, you can donate to organizations designed to help reserve wetlands, work to protect local wetlands, & reduce the amount of ferilizers you use in your gardens.
