Detailing the emotional and social lives of the Sawtooth Pack, the authors recount wolf behavior rarely documented: grief at the death a pack mate; exuberant play and friendships; excitement over the birth of pups; and the shared role of raising young pack members, teaching them needed skills. They describe the reintroduction of wolves into Yellowstone National Park and the cascade of positive results that followed. The return of wolves has helped revitalize the park's ecosystem, influencing elk, birds of prey, pronghorn, aspen trees, and trout. But the demonization of wolves continues as they struggle to reestablish their foothold in the American West. Ranchers, hunters, and biologists work to adapt to innovative solutions that encourage coexistence and reduce conflict. This book opens a window into the unseen lives of wolves by two people who lived in their midst.
