Publisher's Synopsis
Our natural world is increasingly fragile. Now more than ever, it's important to learn about keystone species--those species whose removal can topple entire ecosystems. Beavers create and maintain their own habitat. They alter the landscape to suit themselves, thereby providing homes for a myriad of other plants and animals. This book introduces kids to the concept of keystone species and describes beavers' important role in their habitat. Simple text, full-color photographs, and fascinating fact boxes help kids understand beavers, their wetland habitat, and all the other creatures that share their ecosystem.
