The federal government could buy about 551 acres near Mammoth Cave National Park and add it to the park. The bill also updates an old land-buying cap so it keeps up with inflation.
Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.
Mammoth Cave National Park Boundary Adjustment Act of 2025 is a Senate bill in committee. The latest recorded action: Read twice and referred to the Committee on Energy and Natural Resources.
Latest action on S. 1674: Read twice and referred to the Committee on Energy and Natural Resources.
Who this affects: This bill mainly affects people and groups connected to Mammoth Cave National Park and nearby land. That includes nearby landowners, park visitors, local tourism businesses, conservation groups, and the Interior Department staff who manage park land. The biggest direct change is that some nearby land could become part of the national park if the federal government buys it.
Why this matters: The bill matters because it could change the size and shape of Mammoth Cave National Park. More nearby land could move under federal park management if the government buys it. The inflation update also matters because an old $350,000 limit may not match current land prices. The bill could help protect land around the park, but it could also raise concerns about federal land ownership and local control.
