The importance of biodiversity in the Great Lakes watershed cannot be overemphasized. The thousands of kinds of plants and animals that live in the lakes' habitats affect the health of the lakes, just as the lakes' health affects the wildlife. Readers learn about the many habitats of the Great Lakes region and conservation efforts that continue to restore and protect them. Full-color photographs accompany in-depth profiles of plants and animals, such as the Canada goose and brook trout, in the region. Sidebars introduce even more wildlife information, which augments the social studies and science curriculum students learn in the classroom.
