Wolf Matriarchs of Yellowstone - PB (Paperback) (ISBN-13: 9781963637847)

In 1926, wolves from Yellowstone National Park (YNP) were killed off, leaving little to no predators to maintain a healthy ecosystem. Aldo Leopold, a prominent conservationist, realized the park's error and promoted bringing back the wolves. In 1973, with the Endangered Species Act, YNP decided to bring them back. Join us as we tell you the story of their return, especially Wolf #7 and Wolf #9, the Matriarchs of Yellowstone National Park.

This book includes a photo and fact section about wolves and the environment.
