Excerpt from the report: The USDA National Animal Health Monitoring System (NAHMS) conducted its first national study of the U.S. ranched-bison industry in late 2014 and early 2015. One objective of the NAHMS Bison 2014 study was to provide a baseline description of the U.S. ranched-bison industry. This info sheet summarizes results on basic operation characteristics, including bison inventory, reasons for having bison, herd additions and removals, marketing, and plans for the herd.
