Marsh-Billings-Rockefeller National Historical Park Establishment Act Amendments Act of 2024

This bill amends the Marsh-Billings-Rockefeller National Historical Park Establishment Act to expand the park's boundaries. It adds specific areas to the historic zone (including the mansion and surrounding buildings) and protection zone (Billings Farm), while dividing the King Farm between these zones. The bill also clarifies land acquisition rules for the King Farm, allowing the park to use it for agriculture, conservation, and education that preserves its historic character. Finally, it establishes a National Park Service Stewardship Institute at the park to advance conservation practices through workshops and research.
