Conservation Change

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 14 wolves from the Canadian Rockies to Yellowstone. This is the story of their homecoming.

Author Gail Herman presents both sides of the debate in this fact-based, fair-minded, and well-researched book that looks at the subject from many perspectives, including scientific, social, and political.
