Theodore Roosevelt National Park Wild Horses Protection Act
Introduced April 9, 2025 · Last action June 15, 2026
Plain English Summary
This bill requires the Department of the Interior to maintain at least 150 genetically diverse wild horses in the South Unit of Theodore Roosevelt National Park and prohibits removing them except in emergencies or for public health and safety reasons. The bill requires the Interior Department to develop a management plan within 120 days and to annually monitor and report on the herd's population, structure, and health.
Who benefits
Wild horse advocacy groups, Theodore Roosevelt National Park visitors interested in viewing wild horses, and tourism businesses in the Medora, North Dakota area that benefit from horse-based park attractions
Who pays / loses
National Park Service budget (for the costs of managing, monitoring, and maintaining a minimum herd size); ranchers with grazing permits or interests near the Park (if herd management affects rangeland); competing park management priorities if herd maintenance diverts resources from other Park operations
Funding & Lobbying Interests
Wild horse advocacy organizations (such as American Wild Horse Campaign and similar groups) that have lobbied for protections of wild horse herds on federal and park lands typically support such legislation. Tourism operators in the Theodore Roosevelt National Park region who benefit from visitors attracted to wildlife viewing have a financial interest in maintaining the herd.
Political Impact
Affected Groups
Approximately 200,000+ wild horse advocacy supporters nationally who prioritize preservation of wild herds; Theodore Roosevelt National Park visitors (approximately 600,000+ annual visitors to the park); residents of Medora, North Dakota and surrounding areas dependent on park-related tourism; Park Service staff responsible for managing the herd and monitoring its health.
Political Subtext
Proponents argue the bill preserves a cultural and ecological symbol of the American West and maintains a visitor attraction. Critics argue that mandatory minimum herd sizes may conflict with natural resource management goals, potentially strain park budgets, and may lead to ecological impacts if the herd exceeds the carrying capacity of the landscape. Non-partisan evidence on wild horse management from the Interior Department and GAO shows tension between herd preservation mandates and rangeland sustainability across federal lands, though Theodore Roosevelt National Park's specific carrying capacity is not a subject of published CBO or GAO analysis.
Real-World Stakes
If this passes, the National Park Service must allocate resources to ensure at least 150 horses remain in the South Unit indefinitely. The Park Service currently manages wild horse populations on other federal lands under the Wild Free-Roaming Horses and Burros Act of 1971; mandatory minimums have in some cases led to population growth that Park managers argue damages vegetation and water sources. The Park Service will be required to document and report annually on herd health and genetics, which may necessitate veterinary and monitoring expenditures. Removal of horses that exceed genetic diversity targets or threaten park resources will be legally constrained, potentially requiring the Service to seek emergency declarations or public health justifications for any removals—a process that has proven litigious on other federal lands.
