American Prairie scored a significant legal victory this week when a federal judge granted the conservation nonprofit a preliminary injunction in its ongoing fight with the state of Montana over grazing its bison herd on public lands. The ruling temporarily blocks the state from enforcing restrictions that had hampered the organization's ability to run its roughly 900-head bison herd on federal allotments adjacent to its private holdings in north-central Montana.
The dispute is years in the making. American Prairie has been working to restore a large-scale native grassland ecosystem across a swath of Montana's high plains, assembling private land and seeking grazing access on intermingled public acres. The state and some federal agencies have pushed back, and the organization lost its federal grazing permits earlier — a separate blow that the injunction does not directly address. The bison question has put American Prairie at odds with neighboring ranchers and state officials who argue the nonprofit's model threatens traditional livestock operations in the region.
The organization made headlines in late 2023 when it transferred 107 bison to tribal nations in Montana, South Dakota, and Washington — a move framed as a step toward Indigenous-led bison recovery. Critics read it differently, as a way to generate goodwill while the legal battles played out. The preliminary injunction ruling suggests at least one federal judge found enough merit in American Prairie's legal arguments to pause state enforcement while the underlying case proceeds.
A preliminary injunction is not a final ruling. The case will continue in federal court, and the state is expected to contest the matter further. For Montanans watching the long-running tension between large-scale conservation efforts and agricultural communities, the injunction is the latest chapter in a fight that shows no sign of reaching a quick resolution.
