The American buffalo—those ornery, hairy prairie beasts that reign as the official mammal of the United States—have joined wind turbines, electric cars, and climate researchers in the crosshairs of the Trump administration.

Acceding to anti-bison grumbling from cattle ranchers and Republican politicians in Montana, Interior Secretary Doug Burgum in January proposed canceling leases for buffalo grazing on federal land managed by the Bureau of Land Management (BLM).

Now, in the MAGA era, with Interior reversing the Biden administration’s determination that conservation is a use of BLM land on par with grazing and resource extraction, Burgum has ruled that since bison here in north-central Montana are not being raised for “production-oriented purposes,” they have no legal right to roam, wallow, or munch grass on land leased from the bureau.
