For millions of people around the world, the image of wolves running free through Yellowstone National Park has become the ultimate symbol of the American wilderness. The release of thirty-one Canadian gray wolves in 1995 and 1996 began what is arguably the most successful, and at the same time controversial feat of conservation in our nation's history.

Decade of the Wolf is an unforgettable account of the wolves themselves, as well as of the scientists who are faithfully following them through the wilds of Yellowstone. Published on the tenth anniversary of this historic endeavor, here are exciting new discoveries about wolf behavior, as well as the remarkable effects these animals are having on their environment. From bison to grizzly bears, beetles to bald eagles, willows to grasses, an astonishing range of species is being affected by the return of this powerful predator. As the book's co-author biologist Douglas Smith describes it, "wolves are fast becoming to Yellowstone what water is to the Everglades."

Complete with more than 50 full-color photographs--many never seen before--here is a book to mark the end of the opening act of this inspired, often tumultuous tale of preservation.
