Die-Off Tables

Western U.S. & Canada: 1900-1995

INTRODUCTION
This is a sampling of some recorded North American bighorn die-offs that definitely or likely happened becaused of domestic sheep contact. Some 1881-2005 table die-offs also appear in this table. Many of the listings below are from penned experiments. Domestic sheep culpability in open range epizootics can be more difficult to definitively determine.
