The "Protect our Parks Act of 2025" directs the Secretary of the Interior to ensure that all National Park Service units are fully staffed to enhance visitor safety and enjoyment, and to protect natural and cultural resources, specifically requiring the filling of all maintenance staff positions . It further mandates the reinstatement of individuals involuntarily removed or terminated from Service employment between January 20 and February 25, 2025, using previously appropriated funds. Additionally, the bill explicitly authorizes the Secretary to continue all National Park Service projects for which funds are authorized or appropriated under several significant existing laws. These include the Federal Lands Recreation Enhancement Act, the Great American Outdoors Act, the Infrastructure Investment and Jobs Act, and the Inflation Reduction Act of 2022. This ensures the uninterrupted progress of critical park operations and development initiatives funded by these acts.
