Living in Harmony with Wetlands
Not All Wetlands Are Alike
Some wetlands, like tidal and freshwater marshes, have ponds that become
deeper and shallower with the seasons. While others, like coastal marine
wetlands, may be flooded all year. Prairie pothole wetlands may be dry for most
of the year. Fifty percent of North America's waterfowl use them for breeding
grounds.
If you're a Southeasterner, there's probably a swamp or floodplain forest
near you. These are known for trees, shrubs, and other woody plants that have
adapted to floods, ponds, and water-saturated soils. They offer habitat for
wildlife and store flood water and trap sediment.
If your home is in the Northeast or the Appalachian Mountains, you've
probably heard about bogs. Thousands of years ago, bogs were formed by glaciers.
Today, they are havens for evergreen trees, shrubs, and sphagnum moss.
In California's Central Valley, the Gulf and East Coasts, and along
Midwestern streams not all wetlands are natural. Some, like the greentree
reservoirs, are artificial. These are often intentionally flooded to give
waterfowl a winter home. Water levels are lowered when the waterfowl are gone.
But no matter where the wetland is, you'll find that...
