"From 1987 through the end of 2000, wolves killed only 148 cattle and 356 sheep, according to the Fish and Wildlife Service. In response, biologists trapped and moved 99 wolves, and killed 84 others."

"Cattle ranchers in Montana, Idaho, and Wyoming lost almost 100,000 animals to weather, disease and calving in 1995 alone, according to U.S. Department of Agriculture statistics."

"Most wolves are happy to eat elk and never develop a taste for stock, Bangs said."

"Bangs said young wolves learn from each other, so killing them is necessary to head off a livestock-killing ‘culture.’"

DOW in 2001, "bought hay to keep livestock out of wolf territory near Riverton, WY, during the calving season."

The Whitehawk pack in Idaho: "In late June, the pack killed 13 sheep, a calf, and a guard dog after the livestock owner neglected to erect an electric fence given to him by the forest service. Once the fence went up, no more attacks were reported."

"[Doug] Smith’s carcass studies show the average wolf-killed cow elk is 14 years old, past the prime breeding ages of 2 to 9. On the other hand, the average cow killed by a hunter is 6 years old. ‘When those elk make it to age 2, they have a darn good chance of living to 10,’ he said, ‘So who’s killing prime elk?’"
