The National Park Service proposes to amend its regulations for hunting, fishing, trapping, and other natural resource harvest in national preserves in Alaska and for the procedures used to restrict public use and access in Alaska park lands. These changes restore regulations adopted to implement the Alaska National Interest Lands Conservation Act of 1980 (ANILCA; P.L. 96-487) that were in effect for several decades. Rulemaking in 2015, 2017, and 2024 preempted methods of state-authorized fish and wildlife harvests, revised codified and established procedures for restricting public access and activities in Alaska park lands, and added a severability provision, among other changes. The revisions in this proposed rule are consistent with Executive Order 14153, Executive Order 14192, and Secretary of the Interior Order 3422.
