Wolf depredation trends and the use of fladry barriers to protect livestock in western North America
In Alberta, Canada (1982-2001), and in Idaho, Montana, and Wyoming, United States (19872001), wolves (Canis lupus) killed various domestic animals, among which the major prey were sheep in the United States (68%, n = 494) and cattle in Canada (95%; n = 1633). Under recovery programs, the wolf popula...
