Where did all the wolves go? The birds, the fish, and the beavers? When the top predator was wiped out, the balance of nature in Yellowstone National Park was disrupted. The circle was broken.

Written in a lyrical style, Why Wolves Matter is an ecological tale that helps children to understand the interconnectedness of all things in the natural world. Once all the wolves were gone, the elk population grew so large that the trees and vegetation on which they fed disappeared, throwing the Park and the remaining wildlife into disarray.

A non-fiction picture book, including a timeline and bibliography, Why Wolves Matter is about the importance of the top predator in nature, how balance was restored in Yellowstone National Park, and the circle made whole again--with important historical and scientific relevance for children.

A deeply committed animal person, Karen B. Winnick has created many picture books about animals. She's a member of an oversight commission for the Los Angeles Zoo, and a member and supporter of many groups working to save animals, including wolves.
