WASHINGTON – U.S. Senators Martin Heinrich (D-N.M.), Ranking Member of the U.S. Senate Energy and Natural Resources Committee, and John Hoeven (R-N.D.), Chair of the U.S. Senate Appropriations Subcommittee on Agriculture, Rural Development, Food and Drug Administration, and Related Agencies, announced that the U.S. Senate passed a bipartisan resolution they led to designate November 1, 2025, as National Bison Day.
"Bison have been a critical part of our culture for generations — in New Mexico, across the West, and especially in Indian Country. They are an enduring symbol of American strength and resiliency," said Heinrich. "I’m proud to lead this bipartisan resolution with Senator Hoeven to recognize our national mammal and raise awareness for the ongoing efforts to restore this unique species."
The full text of the resolution is here.
Heinrich and Hoeven introduced their bipartisan National Bison Legacy Act in 2015, and the legislation was signed into law in 2016. The National Bison Legacy Act recognized the bison’s significance in American history and designated it as the United States’ national mammal.
