Students at Timberline High School in Boise, Idaho, have been studying a group of wolves — known as the Timberline wolf pack — in a nearby national forest since 2003. But sometime in the spring, biologists who track the pack noticed its den was empty, which was unusual, said wolf conservationist Suzanne Asha Stone.

After conservationists obtained a wolf “mortality list” from the state’s Department of Fish and Game, they realized pups in the Boise National Forest’s Timberline pack were killed by the U.S. Department of Agriculture’s Wildlife Services branch, Stone told The Washington Post.
