Whether you call it a swamp, a bog, a fen, a march, a slough or a quagmire, a wetland is a remarkable world where land and water meet. Wetlands naturally filter pollution and sediment from our water, control flooding and protect stream and riverbanks from erosion. They also provide a home to many plants and animals from microscopic algae and moss to muskrats and herons. This informative book contains easy-to-follow experiments and projects so readers can learn first-hand just how important wetlands are. It's an excellent resource for home, school, nature groups and summer holidays.
