Here is the fascinating true story of the wolves who restored the ecosystem at Yellowstone National Park, written by Catherine Barr and illustrated by award-winner Jenni Desmond.

In the 1930s, the last wolves disappeared from Yellowstone National Park.

Without them, elk herds overran the plains. Bears starved, rabbit families shrunk, and birds flew away to new homes. Then plants and trees started to die off, too-even the flow of rivers was affected.

Could the park be saved … by the wolves it had lost?

After years of planning, in 1995 a team of experts was ready to find out. They carefully relocated fourteen wolves from the Canadian Rockies to Yellowstone. This is the story of their homecoming.

Engaging, informative, and hopeful, The Wolves of Yellowstone shows us that every creature plays a role in sustaining a thriving ecosystem.
