"This works well with wolves, but not against men with guns, and in fact led to the extinction of the Alaskan musk ox in the late 1800's. In 1930, 34 musk oxen captured in East Greenland were brought to Fairbanks and later transported to Nunivak Island and released to re-establish a musk ox population in Alaska. Musk oxen thrived on Nunivak Island and increased to an estimated 750 by 1968. In 1990, approximately 2,220 free-ranging musk oxen resided in Alaska."
