In February 2026, the Department of the Interior issued Public Land Order No. 7966 , effectively revoking decades of federal protection for approximately 2.1 million acres of land in Alaska’s Dalton Utility Corridor.
While framed as a move to satisfy state land entitlements and promote economic development, the action poses a direct threat to the region's ecological health and the survival of the caribou herds that constitute the primary livelihood for Northern rural communities.
The revocation of Public Land Orders (PLOs) 5150 and 5180
removes barriers to mineral entry, mining, and oil and gas leasing.
Large-scale industrialization in the Arctic—a region already warming at nearly four times the global average—accelerates habitat fragmentation. The introduction of heavy machinery, road networks, and potential chemical runoff from mining operations risks contaminating pristine watersheds north of the Yukon River, disrupting the delicate balance of the permafrost-dependent ecosystem.
For the Gwich’in and other Indigenous peoples represented by the Tanana Chiefs Conference the caribou are not merely a resource; they are a cultural and biological lifeline. The Dalton Corridor serves as a critical migratory path and grazing area.
Under [ANILCA] (Alaska National Interest Lands Conservation Act), federal management prioritized rural subsistence rights. By shifting this land toward state selection and private development, the federal government reduces its oversight, potentially allowing industrial interests to override the "subsistence priority" that protects Indigenous food security.
The move to open over two million acres to industrial exploitation prioritizes short-term economic gain over long-term environmental stability. Protecting the caribou and their habitat is essential to maintaining the "health of the earth" in the Arctic and ensuring that Northern populations can continue their traditional way of life without the looming threat of industrial displacement.

Federal Register. (2026, February 25). Public Land Order No. 7966; Partial Revocation of Public Land Order Nos. 5150 and 5180; Alaska.
At 8 a.m. Alaska time on March 27, 2026, the lands described in Paragraph 1 shall be open to all forms of appropriation under the general public land laws, including location and entry under the mining laws, leasing under the Mineral Leasing Act of February 25, 1920, as amended, subject to valid existing rights, the provisions of existing withdrawals, other segregations of record, and the requirements of applicable law. All valid applications received at or prior to 8 a.m. Alaska time on March 27, 2026, shall be considered as simultaneously filed at that time. Those received thereafter shall be considered in the order of filing. Appropriation of any of the lands referenced in this PLO under the general mining laws prior to the date and time of revocation remain unauthorized. Any such attempted appropriation, including attempted adverse possession under 30 U.S.C. 38, shall vest no rights against the United States. State law governs acts required to establish a location and to initiate a right of possession where not in conflict with Federal law. The BLM will not intervene in disputes between rival locators over possessory rights since Congress has provided for such determinations in local courts.
Subsistence Priority: Title VIII of ANILCA mandates that rural Alaskans have a priority right to harvest fish and wildlife on federal lands.
Before any "withdrawal, reservation, lease, permit, or other use, occupancy, or disposition" of public lands, the Bureau of Land Management (BLM) must evaluate the effect on subsistence. Opponents argue that revoking protections for 2.1 million acres in the Dalton Utility Corridor without a rigorous evaluation of how mining and leasing will deplete caribou and moose populations violates this mandate. If the BLM has not sufficiently proven that this land opening won't significantly restrict subsistence uses, the PLO can be struck down in federal court.
International Agreement on the Conservation of the Porcupine Caribou Herd (1987): This treaty between the U.S. and Canada requires both nations to protect the herd's habitat and migration routes. Because the herd moves between the Yukon and Alaska, unilateral industrial development that threatens their calving grounds or migration paths can be viewed as a breach of international legal obligations.
Habitat Fragmentation: The "Caribou People" (Gwich'in) argue that opening these lands for mining and leasing under the Mineral Leasing Act of 1920 creates "death by a thousand cuts." Even if one mine is small, the cumulative infrastructure (roads, pipelines, noise) disrupts the delicate transboundary migration patterns protected by these conservation frameworks.
"Open to all forms of appropriation" Conflicts with the ANILCA requirement to prioritize subsistence over industrial use.
"Mining laws... leasing" Potential violation of Transboundary Caribou Agreements if development occurs on critical migration corridors.
"BLM will not intervene in disputes" Critics argue this "hands-off" approach ignores the government's Trust Responsibility to protect indigenous lands and resources from encroachment.
The claim of illegality isn't necessarily about the form of the PLO, but the failure to follow the process:
Failure to Consult: Many tribal nations argue they were not properly consulted as sovereign entities.
Inadequate Environmental Review: Claims that the Environmental Impact Statement (EIS) failed to account for the catastrophic decline in caribou populations.
Treaty Violations: This is a breach of international caribou conservation duties.
