BLM Revokes Bison Grazing Permit on Montana Prairie
The Bureau of Land Management (BLM) announced it will rescind the American Prairie Foundation’s grazing permit for about 900 bison on federal land in Phillips County, Montana. Citing the 1934 Taylor Grazing Act, the agency argues the acreage should serve livestock production. The revocation, not yet in force, could take effect in spring.
Legal Context and Background
The Taylor Grazing Act of 1934 governs public-land grazing. For more than four decades, the BLM has treated bison as eligible livestock, issuing permits after environmental reviews. The foundation’s permit allowed a herd while supporting public access and tribal herd-building.
Principal Actors
The American Prairie Foundation, owner of the 900 bison, is led by Landscape Stewardship Director Scott Heidebrink and Executive Director Alison Fox. Montana Governor Greg Gianforte and Interior Secretary Doug Burgum support the move. Ranchers, Republican lawmakers and business leaders back it, while environmentalists and Native American tribal leaders oppose it.
Government Positions
Governor Gianforte said public lands must stay “accessible and productive” and not be “locked away for special interests.” Interior Secretary Burgum supports selling federal lands to reduce the debt. The BLM says the revocation complies with the 1934 grazing statute.
Opposition Arguments
Environmental and tribal leaders argue the revocation threatens conservation and tribal herd-building. The American Prairie Foundation calls it “arbitrary,” warning it jeopardizes public access, electric-fence grazing and meat donations. Fox says the abrupt change creates “immense uncertainty” for tribes, ranchers and conservation partners.
Discrepancies and Unknowns
The BLM classifies the bison as wildlife, while the foundation argues they are livestock, citing tagging, vaccination and lease agreements with cattle ranchers. The foundation estimates relocation costs in the hundreds of thousands of dollars. How the land will be allocated among ranchers remains unclear.
Potential Consequences
If enacted, the revocation could force herd removal, incurring relocation costs and disrupting conservation and tribal programs. It also signals a shift in federal land-use policy that may affect grazing permits and public-land management.
