The State of Montana and federal defendants filed a joint motion on Monday to voluntarily dismiss the ongoing lawsuit concerning bison management in Yellowstone National Park without prejudice.

Litigation Background

The legal dispute centered on the administration’s interpretation of the 1934 Taylor Act. District Court Judge Brian Morris previously issued a 29-page ruling criticizing the Trump administration’s reading of the statute. The decision highlighted significant disagreements between state and federal authorities regarding wildlife management protocols.

American Prairie, an organization involved in the litigation, had sought a temporary restraining order and preliminary injunction by September 15 to maintain the status quo while the case proceeded. The joint motion for dismissal effectively halts the current legal proceedings, though filing without prejudice allows the parties to potentially reopen the matter later.

Bison Management Actions

The lawsuit emerged amid active bison management efforts in the region. On July 23, 2025, authorities returned previously free-roaming bison to the Crow Tribe’s bison range. This transfer was part of broader efforts to manage herd sizes and address concerns from local livestock producers.

The conflict reflects ongoing tensions between conservation groups, tribal nations, and government agencies over how to balance wildlife preservation with agricultural interests in Montana. The voluntary dismissal removes the immediate legal pressure but does not resolve the underlying policy disagreements.

Park Visitor Trends

Yellowstone National Park reported 856,467 recreationists in August, marking a 3% decline from last year and a 7% drop from the record-setting year of 2021. The visitor data suggests shifting patterns in national park usage that may influence future management decisions.

The dismissal motion comes as wildlife activity increases across Montana, with bears pushing into residential areas due to late frosts stripping natural food sources. These ecological pressures add complexity to land management strategies in the region.
