Wolves are suspected of killing a dog, goat and horse this summer. The incidents were investigated by the tribe, the U.S. Fish and Wildlife Service and U.S. Department of Agriculture Wildlife Services in late July. Mark Collins of Wildlife Services said there was insufficient evidence to link the killings to wolves. One person reported seeing a collared wolf near Bovill, but flights over the area could not pick up a signal, said Keith Lawrence, Nez Perce wildlife manager. He said it is likely wolves will frequent the north-central Idaho mountains as the packs expand. At last report there were about 160 wolves in Idaho, but numbers of breeding pairs and new pups have not yet been tallied this year. Ron Gillett of the Central Idaho Wolf Committee, which advocates the immediate removal of wolves, claims wolves are wiping out big game herds and causing economic hardships on people like him who depend on hunters to support their businesses. He and the committee successfully added a plank to the Republican Party of Idaho that calls for removing wolves from the state. The tribe has been recognized by Harvard University for its management efforts.
