Katahdin Woods and Waters National Monument Access Act

This bill allows the Secretary of the Interior to voluntarily acquire specific land within a defined "authorized acquisition area" (outside the current monument boundary) to expand Katahdin Woods and Waters National Monument in Maine. It prohibits the use of eminent domain for land purchases and requires boundary adjustments upon acquisition. The bill maintains existing hunting, fishing, and outdoor recreation rights on newly acquired land, and permits noncommercial hand-gathering of fiddlehead ferns under certain conditions. It also directs the Secretary to collaborate with local communities on public education about the area's history and management, while preserving existing timber access rights.
