Gibbons introduces the concept of wetlands (swamps have trees, and marshes do not) and distinguishes between the fresh-and saltwater varieties of each. She describes the amazing array of plants and animals found in these ecosystems and explains how these areas store freshwater, prevent flooding and erosion, and serve as a refuge for migratory animals. Large, colorful illustrations dominate every page and include many interesting details; oversize labels identify most terms and species. Appended with a map of major wetland areas in the U.S. and Canada and a page of other interesting facts, this will make an excellent introduction for primary-grade students.

Gibbons balances a succinct, informative text with well-labeled watercolors, which often contain cutaway views revealing the underwater wildlife in addition to the plants and animals that live alongside the water. The text notes that the great diversity of life found in many wetlands is being threatened. An appended map lists over a dozen parks and wildlife refuges in the United States and Canada.

Gr 1-3--In this excellent introduction to the delicate world of ecosystems, Gibbons describes the symbiotic relationships between plants and animals with just the right amount of detail for young readers. The differences and similarities between marshes and swamps are discussed and the evolution of the wetlands is explained in simple terms. Watercolor paintings done in muted, natural tones teem with creatures, labeled and shown in their natural habitats. After decrying the destruction of these important wetlands that upsets the delicate balance of nature, Gibbons then describes methods currently being used to protect and preserve them. A map of swamps and marshes in North American and a fact sheet on wetlands are included. Good easy-to-read nonfiction.--Kit Vaughan, J. B. Watkins Elementary School, Midlothian, VA
