The Mechanics of the Monument Reduction: How the President's Proclamation Strips Protections from Bears Ears and Grand Staircase-Escalante

When travelers stand beneath the towering red rock twin buttes of Bears Ears, it is easy to assume that a 'National Monument' designation is as permanent as the sandstone itself. The common misconception is that once a president protects a landscape, it remains preserved forever, shielded from development by an unbreakable federal lock. But the legal framework guarding this vast Utah wilderness is far more fragile. The Antiquities Act of 1906 was designed to allow presidents to quickly draw a protective boundary around federal lands without waiting for Congress—but it left a gaping legal loophole about how those protections can be undone.[1]

The core mechanism of creation is surprisingly simple. A president issues a public proclamation identifying specific 'historic landmarks, historic and prehistoric structures, and other objects of historic or scientific interest.' The law requires that the reserved land be confined to the 'smallest area compatible with the proper care and management of the objects to be protected.' For travelers planning a trip to a newly minted monument, this stroke of a pen instantly shifts the land's priority from resource extraction to preservation and recreation.[6]

But what happens when a subsequent administration decides that boundary was drawn too wide? While the Antiquities Act explicitly grants the power to create monuments, it remains entirely silent on the power to reduce or revoke them. This century-old silence has fueled a fierce legal debate over whether the authority to designate a monument implicitly includes the authority to diminish it.[1]

On one side of the canyon is the 'one-way ratchet' argument. Legal scholars and environmental groups argue that the U.S. Constitution gives Congress, not the president, the ultimate authority over public lands. They contend that the Antiquities Act is a highly specific, limited delegation of that authority—a one-way street meant only for protection, leaving any decisions to shrink or abolish a monument strictly in the hands of lawmakers.[3]

The executive branch views the mechanics differently. A 2025 memorandum from the Department of Justice's Office of Legal Counsel concluded that the Antiquities Act does, in fact, permit a president to alter a prior declaration. The memo argued that a president can determine that previously identified objects no longer require the Act's protections, effectively erasing the reservation of that land and returning it to multiple-use status.[2]

Bears Ears and the neighboring Grand Staircase-Escalante have become the primary testing grounds for these legal mechanics. Their boundaries have expanded and contracted dramatically across multiple administrations. Most recently, a presidential proclamation executed a 90 percent reduction, stripping monument status from nearly 3 million acres of high desert, slot canyons, and sagebrush plateaus.[5]

When a president signs a proclamation reducing a monument, the excluded lands do not suddenly leave federal ownership. Instead, they revert to the general public domain. They are typically managed by the Bureau of Land Management or the U.S. Forest Service under standard multiple-use mandates, which balance recreation with commercial interests.[6]

For the landscape itself, the effects of this administrative shift are profound. Once the protective monument overlay is removed, the land becomes eligible for new mining claims, oil and gas leasing, and modified grazing regulations. In Grand Staircase-Escalante, this means areas containing internationally significant paleontological sites—where new dinosaur species are still being unearthed—are suddenly opened to potential commercial development.[3][5]

The mechanics of monument reduction also dismantle the human frameworks built to protect them. Bears Ears was unique in the history of American public lands because it established the Bears Ears Commission. This coalition of five tribal nations was tasked with co-managing the ancestral lands alongside federal agencies, integrating traditional Indigenous knowledge into the daily stewardship of the canyons.[4]

When the monument boundaries were slashed, the legal framework supporting the Bears Ears Commission was effectively dissolved. This abrupt end to a first-of-its-kind model for Indigenous leadership in federal land management left tribal leaders without a formal mechanism to guide the preservation of their sacred sites and ancestral migration routes.[4]

Even after a reduction, the transition of the land is not instantaneous. Federal agencies must draft new Resource Management Plans (RMPs) for the excluded acreage. This bureaucratic process requires extensive public comment periods and environmental reviews, meaning that while the land is legally open to extraction, the actual arrival of drilling rigs or mining equipment can take years of administrative procedure.[1]

Because the Antiquities Act lacks a specified reduction process, the final arbiter of these mechanics is the federal court system. Lawsuits challenging the reductions argue that the president exceeded his delegated authority, setting up a high-stakes legal battle that could ultimately force the Supreme Court to define the exact limits of executive power over public lands.[3]

Until the courts issue a definitive ruling, the boundaries of America's national monuments remain tethered to the shifting policy priorities of the executive branch. For now, the mechanics of monument reduction rely on the stroke of a presidential pen, leaving the long-term preservation of these iconic landscapes suspended in years of complex litigation.[1][2]
