Federal policy changes and staffing cuts jeopardize historical preservation efforts in the U.S., notably affecting projects like the Great River Road in southern Louisiana, which aims to honor the history of slavery and landownership transitions post-Civil War. The project, halted after President Trump’s return to office, was poised for National Historic Landmark designation, highlighting significant local history, but faced setbacks due to administrative changes and a 13% workforce reduction at the National Park Service, impacting artifact preservation nationwide. Historians express deep concern over the loss of preservation roles and the potential degradation of over 3 million artifacts housed in national sites.
