In the heart of Wyoming sprawls the ancient homeland of the Eastern Shoshone Indians, who were forced by the U.S. government to share a reservation in the Wind River basin and flanking mountain ranges with their historical enemy, the Northern Arapahos. Both tribes lost their sovereign, wide-ranging ways of life and economic dependence on decimated buffalo. Tribal members subsisted on increasingly depleted numbers of other big gameOCodeer, elk, moose, pronghorn, and bighorn sheep. In 1978, the tribal councils petitioned the U.S. Fish and Wildlife Service to help them recover their wildlife heritage. Bruce Smith became the first wildlife biologist to work on the reservation. “Wildlife on the Wind “recounts how he helped Native Americans change the course of conservation for some of America’s most charismatic wildlife.
