From WesternSlopeNow.com in Colorado:
DENVER (KDVR) — Wolves aren’t the number one cattle killer in Colorado, but they are a growing concern for ranchers already worried about gray wolf reintroduction.
A series of wolf attacks on cattle in northern Colorado have claimed several cattle and prompted wildlife managers to import wild burros as guard animals. Wolves moving south from Wyoming have caused four such incidents in the last four months, marking the end of an era. Prior to December 2021, Colorado hadn’t seen any wolf attacks since the 1940s.
