The black-footed ferret was once listed as extinct on the prairies of North America. Its population had been devastated by a disease that also reduced its main food source-prairie dogs. This book tells the fascinating story of the black-footed ferret’s rediscovery in 1981 by a dog in Wyoming. Readers will learn how the find inspired a captive breeding program that is restoring not only this prairie species to the wild, but its essential food source as well, the prairie dog.
