What Happened

In May 2026, Interior Secretary Doug Burgum finalized a ban on American Prairie’s bison grazing on Bureau of Land Management land in Montana. The administration claims the ban does not affect tribal herds, but the Coalition of Large Tribes — representing tribes that manage 25,000 buffalo — says that is not true. As written, the rule makes it unlikely any tribal government or tribal citizen herd would ever qualify for a BLM grazing lease.

Burgum also repealed the Biden-era Public Lands Rule, which had put conservation on equal footing with mining, drilling, and logging. New regulations ease access specifically for livestock grazing.

Meanwhile, the federal grazing fee remains $1.69 per animal unit month. Private land grazing costs $20 or more in most Western states.

WhereCost per animal unit month
Federal land (BLM)$1.69
Private land (Western states)$20+

The $1.35 floor was set by a 1986 executive order and Congress has never updated it.

Why This Matters Beyond Montana

Bison restoration is a tribal sovereignty issue, a wildlife management issue, and a public land accountability issue at the same time. When the government bans bison from public land while subsidizing cattle at a fraction of market rates, the question is not really about grazing. It is about who public land is for.

Earthjustice filed a legal challenge calling the decision arbitrary. The House Natural Resources Committee has jurisdiction but has not scheduled oversight hearings.

What You Can Do

  1. Go to the Environment actions page and send a letter on public land protections.
  2. Call your representative and ask them to co-sponsor H.R. 5785, the Voluntary Grazing Permit Retirement Act. It lets ranchers voluntarily waive federal grazing permits to permanently restore wildlife corridors and reduce administration costs.
  3. Send this to someone who hunts, fishes, hikes, or ranches on public land. They have a stake in how BLM manages these leases.
