Requires the Secretary of the Interior to use funds already provided to ensure National Park Service units are fully staffed for visitor safety, enjoyment, and resource protection, and to fill all maintenance staff positions, with those actions to occur within 30 days of enactment. It also directs reinstatement of any National Park Service employees who were involuntarily removed or otherwise terminated between January 20, 2025 and the date of enactment.

Directs the Secretary to continue carrying out any National Park Service projects that have funds authorized or appropriated under four specified federal laws (Federal Lands Recreation Enhancement Act; Great American Outdoors Act; Infrastructure Investment and Jobs Act; and the Inflation Reduction Act of 2022). The law does not appropriate new funds but requires use of existing funds and continuation of funded projects to maintain park operations and project momentum.
