Bob Hayes researched wolves in the Yukon for 20 years. Using a combination of narratives and easy-to-follow essays, his book follows the history of the Yukon wolf from the end of the Ice Age to present day. Bob Hayes also explores his original research into wolf relations to moose, caribou, mountain sheep, ravens, grizzly bears and human hunters. The last chapter tells why broad-scale killing of wolves to increase game should end. Finally, Wolves of the Yukon raises profound arguments about how to value and conserve the largest remaining tract of complete wilderness on the continent.
Bob Hayes was the Yukon wolf biologist for nearly two decades. He radio-collared hundreds of wolves, pioneering research on the kill rate by wolves on moose, Dall's sheep and woodland and migratory caribou. He also studied the effects of wolf control on wolf and prey populations, guiding original research on non-lethal ways of controlling predation. He has published in wildlife science journals and academic books, and was a member of the IUCN Wolf Specialist Group. He is retired and he and his wife, Caroline, have lived in the Yukon for 42 years.
