Students have tracked and studied a group of wild wolves, called the Timberline pack, since 2003. The biologists who track the pack noticed its den in the Boise National Forest was empty in the spring of 2020. The Idaho Department of Fish and Game wolf mortality list showed that pups were killed by the U.S. Department of Agriculture Wildlife Services branch. The federal agents killed the pups in order to force the adult wolves to relocate and to reduce the predators' population as they can pose a threat to wildlife and livestock.
