In this unique series, you will learn the recovery stories of threatened animal species from around the world. Explore the dangers each species faces and meet the dedicated people working to protect animals and their habitats. Discover the challenges, failures, and ultimate success of each inspiring journey to bring a species back from the brink of extinction. Once listed as extinct in North America, the black-footed ferret was rediscovered in 1981 by a dog in Wyoming. This inspired a captive breeding program that is restoring not only this prairie species, but its food source as well, the prairie dog.
