(LEWISTON) – The Nez Perce Tribe in northern Idaho is using a $200,000 federal grant to monitor bighorn sheep along the Salmon River near Riggins. The tribe plans to use radio collars on ewes to research why their lambs are dying. Officials say disease from possible contact with domestic sheep may be to blame. Idaho’s bighorn sheep population has been cut in half since 1990 to just about 3,500 animals.
