This bill expands Big Bend National Park and clarifies federal boundary authority and mapping to boost conservation and transparency, but it centralizes decisionmaking, can lock in boundaries, may restrict nearby land uses, could slow acquisitions, and increases long‑term management responsibilities.
Visitors and nearby rural communities gain roughly 6,100 acres added to Big Bend National Park, and those acquired tracts will be managed under federal park laws, expanding recreation, habitat protection, and cultural-resource conservation.
Park managers, the Department of the Interior, and local governments get clearer, legally anchored boundary authority—tying the Park to the U.S. Code citation and specifying the Secretary as the implementing official—reducing legal ambiguity about who administers the park and the boundary.
The public and government stakeholders gain greater transparency because the official park boundary map will be on file and available for inspection at National Park Service offices.
Rural communities and nearby landowners could face new limits on non‑federal land uses near the expanded park boundary, which may reduce local land‑use options and economic activity.
Homeowners and other property owners may block or slow park expansion because acquisitions are voluntary and the Act contains no eminent domain authority, so promised additions could be delayed or never realized.
State and local governments (and federal taxpayers) may face higher ongoing costs or resource shifts because managing and maintaining the additional acreage increases National Park Service operational responsibilities.

Introduced March 25, 2025 by John Cornyn · Last progress June 23, 2025
Adds about 6,100 acres to Big Bend National Park by authorizing the Secretary of the Interior to accept land donations or exchanges shown on a referenced map and to revise the park boundary accordingly. The Secretary must file the map for public inspection and may not use eminent domain to acquire the lands. Acquired lands become part of the Park and are administered under existing federal law and Park Service regulations. The measure defines the map, Park, and Secretary for implementation purposes.
