Bison are political animals. A federal decision to revoke grazing leases for bison on public lands on the rolling plains of eastern Montana is the latest manifestation of long-standing contention. The largest land animal in North America, bison are considered a “keystone” species, meaning they have high ecological and cultural importance.
The May 2026 decision represents a significant setback for a decades-long effort by American Prairie, a private conservation organization, to restore wild bison to the Great Plains. Those in favor of the decision are describing the move as a boon for rural farmers and ranchers because it would reduce competition for grazing lands.
