In a move that has sent shockwaves through the environmental and Indigenous communities, President Donald Trump signed two executive orders on Monday that drastically reduced the size of the Bears Ears and Grand Staircase-Escalante National Monuments in southern Utah. The decision, which effectively guts the protections for some of the most ecologically diverse and culturally significant landscapes in the United States, marks a radical escalation of the administration’s policy toward federal land management. By Monday evening, the monuments, which previously encompassed more than 3 million acres of rugged canyons, high plateaus, and ancient archaeological sites, were whittled down to a combined 302,600 acres—a reduction of approximately 90 percent.
The executive orders represent a return to the "energy dominance" agenda of the first Trump administration, but the scale of these new cuts far exceeds previous efforts. While the administration framed the decision as a victory for local control and public access, legal experts, tribal leaders, and conservationists have denounced the move as an unlawful overreach that prioritizes short-term extractive gains over the long-term preservation of American heritage. The 60-day window before the orders take effect sets the stage for a massive legal battle that could redefine the limits of executive power under the Antiquities Act of 1906.
A Drastic Reversal of Land Protection
The geographic scope of the reduction is unprecedented. Under the Biden administration, Bears Ears National Monument covered approximately 1.36 million acres, while Grand Staircase-Escalante spanned nearly 1.87 million acres. Monday’s proclamations reduced these landscapes to mere fragments of their former selves. Specifically, Bears Ears has been reduced to roughly 150,000 acres, while Grand Staircase-Escalante has been cut to a similar size, leaving the vast majority of the previously protected land open to potential mineral leasing, grazing, and industrial development.
This is not the first time these monuments have been targeted. In December 2017, President Trump signed proclamations to reduce Bears Ears by 85 percent and Grand Staircase-Escalante by nearly half. Those cuts were later reversed by President Joe Biden in 2021, who restored the original boundaries and even expanded certain protections. However, the 2026 orders go significantly further than the 2017 actions, leaving less than a quarter of the acreage that remained even after the first round of shrinking.
During the signing ceremony, flanked by Utah Republican lawmakers, the President claimed that the original monument designations had made it "virtually impossible" for citizens to hunt, fish, or even walk on the land. Fact-checking of these claims, however, reveals them to be largely inaccurate. National monument status generally allows for continued public access for recreation, including hunting and fishing, though it restricts new industrial activity and certain types of motorized vehicle use to protect sensitive cultural and biological sites.
Historical and Legal Context of the Antiquities Act
The legal authority cited for these reductions is the Antiquities Act of 1906. Originally signed into law by President Theodore Roosevelt, the Act grants the President the power to designate federal lands as national monuments to protect "historic landmarks, historic and prehistoric structures, and other objects of historic or scientific interest." Since its inception, the Act has been used by nearly every president to safeguard iconic American landscapes, including the Grand Canyon and Zion, before they were later designated as national parks by Congress.
However, a central legal debate remains: Does the power to create a monument also include the power to diminish or abolish one? Legal scholars like John Ruple, a law professor and program director at the University of Utah’s Wallace Stegner Center for Land, Resources, and the Environment, argue that the Act is a one-way street. Ruple notes that the Antiquities Act does not explicitly grant the executive branch the authority to rescind or significantly shrink monument boundaries; that power, he argues, is reserved for Congress.
The administration’s decision follows a June ruling by the 10th Circuit Court of Appeals, which revived a lawsuit from the state of Utah challenging the Biden administration’s restoration of the monuments. By shrinking the monuments now, the Trump administration may be attempting to render that ongoing litigation moot. If the monuments no longer exist at their restored size, the Department of Justice could argue that the legal challenge against the Biden-era boundaries no longer has a basis, effectively bypassing a final judicial ruling on the extent of the Antiquities Act.
Impact on Tribal Sovereignty and Cultural Heritage
The most profound impact of the executive orders may be felt by the Indigenous nations for whom the land is sacred. Bears Ears, in particular, was the result of a historic collaboration between the federal government and five tribes: the Navajo Nation, Hopi Tribe, Ute Mountain Ute Tribe, Zuni Tribe, and Ute Indian Tribe. It was the first national monument designed to be co-managed by federal agencies and a tribal commission.
The new executive orders effectively disband the inter-tribal working group that led these co-stewardship efforts. Tribal officials reported that they were not consulted prior to the signing of the orders, a move they described as a violation of the federal government’s trust responsibility to sovereign tribal nations.
Davina Smith-Idjesa, a member of the Navajo Nation and a representative of the inter-tribal coalitions, spoke emotionally about the decision during a press conference. She described the landscape not as a political boundary, but as a "grocery store, medicine cabinet, classroom, and church." She highlighted the historical trauma associated with resource extraction in the region, noting that past uranium mining in the Four Corners area led to widespread illness and death among tribal members. The prospect of renewed mining in areas containing ancestral graves and sacred sites is viewed by many in the Indigenous community as a continuation of historical erasure.
Economic Drivers: Mining and Extraction
The administration has been transparent about the economic motivations behind the reductions. The executive orders state that the new boundaries better align with goals for "public land use," which include opening the areas to extraction. The region is known to contain deposits of uranium, coal, and oil and gas reserves.
By removing monument protections, the land reverts to Bureau of Land Management (BLM) status under different management tiers, which typically allow for the staking of new mining claims and the leasing of land for energy development. Proponents of the move, including many Utah state officials, argue that the "lock-up" of these lands has stifled local economies that rely on the extractive industries.
However, critics point to data suggesting that the "monument economy"—driven by tourism, outdoor recreation, and the influx of new residents attracted by protected landscapes—has actually provided a more stable and sustainable economic foundation for rural Utah than the boom-and-bust cycles of mining. Polling consistently shows that a majority of Americans, including those in the West, support the protection of public lands. A 2024 "State of the Rockies" poll conducted by Colorado College found that conservation remains a high priority for voters across the political spectrum in the mountain states.
Broader Implications and Future Litigation
The shrinking of Bears Ears and Grand Staircase-Escalante appears to be part of a broader strategy outlined in "Project 2025," a policy roadmap for the administration developed by the Heritage Foundation. This plan calls for a wholesale review of national monuments and suggests the potential repeal of the Antiquities Act itself to prevent future presidents from "locking up" federal lands.
The administration has already signaled that other monuments may be next. Earlier in 2026, there were internal discussions regarding the elimination of California’s Chuckwalla and Sáttítla Highlands national monuments. While those plans were temporarily scrubbed from public fact sheets, the Department of Justice recently issued an opinion asserting that the President does indeed have the power to review and eliminate national monuments, a significant departure from previous legal interpretations.
The response from environmental organizations has been swift. Groups such as Earthjustice, the Wilderness Society, and the Grand Canyon Trust have vowed to file lawsuits immediately. Tracy Stone-Manning, president of the Wilderness Society and former director of the BLM, stated that the administration is "ignoring the voices of Tribal Nations and the millions of Americans who want these places protected for future generations."
As the 60-day clock begins to tick, the fate of southern Utah’s "red rock country" hangs in the balance. The ensuing legal battle will likely reach the Supreme Court, where the justices will be asked to decide once and for all whether a president can undo the conservation legacy of his predecessors. For now, the landscapes of Bears Ears and Grand Staircase-Escalante remain at the center of a fundamental American conflict: the struggle between the preservation of natural and cultural heritage and the drive for industrial expansion.
