Trump Administration Revokes Bison Grazing Permits on Montana Public Lands

Eviction of Bison from Federal Grasslands
In winter 2026, the U.S. Bureau of Land Management (BLM) cancelled grazing permits that had allowed roughly 900 bison owned by the nonprofit American Prairie to graze on federal grasslands in northern Montana. The agency announced that the land would be reassigned to cattle production, prompting the removal of the herd.
Legal and Historical Background
The permits were issued by several successive administrations, including President Donald Trump’s first term, under the Taylor Grazing Act of 1934, which governs livestock grazing on public lands. For about two decades, American Prairie acquired ranches and grazing leases on the same range, operating within that statutory framework.
Primary Stakeholders
American Prairie, a conservation nonprofit, manages the bison herd; its executive director Alison Fox describes the range as part of the nation’s heritage. Politically conservative ranchers and Republican officials advocate for cattle grazing on the same lands. The BLM, as the federal land manager, enforces the grazing policy. Conservation groups and Native American tribes, which are working to restore their own bison populations, oppose the eviction.
Scale of the Herd and Land Use
The herd consists of approximately 900 bison. American Prairie has spent two decades acquiring the ranches and grazing leases that support the herd on the public range. The BLM’s decision reclassifies the animals as wildlife rather than production livestock, thereby shifting land use from a wildlife presence to cattle production.
Conservation and Tribal Implications
The removal raises concerns about preserving a species once near extinction in the 19th century. Conservation advocates argue the decision undermines broader ecological objectives, while tribal representatives warn that limiting bison on public lands hampers efforts to rebuild culturally significant herds.
BLM’s Official Rationale
The BLM stated that, under the Taylor Grazing Act, federal grasslands should be allocated to “livestock being raised for food, not bison largely enjoying their right to roam.” The agency classified the herd as wildlife, not production livestock, to justify the permit cancellations.
Conservationists and Tribal Opposition
Conservation groups condemned the BLM’s action as a setback for wildlife management. Native American tribes echoed the criticism, emphasizing that the anti-bison measure threatens the viability of tribal bison restoration programs.
Classification Dispute
The BLM treats the herd as wildlife, whereas American Prairie and its allies consider the bison a form of production livestock. No consensus appears in the source material.

Outlook and Potential Developments
The permit revocation has intensified a dispute that pits ranchers and Republican officials against conservationists and tribal groups. The conflict remains active as stakeholders consider the legal, ecological, and cultural ramifications of the BLM’s decision.
