K-12 teachers will enjoy using this guide; it features 70 pages of background material followed by more than 40 cross-referenced activities. Every page is thoughtfully laid out with core text, great photographs, side bars, maps, and illustrations to make information clear and quick to use. Activities are organized into five sections: wetlands definitions, wetlands plants and animals, water quality and supply issues, soils, and people. The appendix offers instructions for planning and developing a schoolyard wetland habitat.
