Frequently Asked Questions
What is the Antiquities Act?
The Antiquities Act of 1906 grants the President of the United States the authority to unilaterally designate federal lands as national monuments to protect significant natural, cultural, or scientific features. It has been used by nearly every president since its inception.
Can a president unilaterally reduce the size of a National Monument?
The legal authority for a president to unilaterally reduce the size of a national monument, once designated, is highly debated. While presidents have historically modified boundaries, significant reductions have faced legal challenges, with courts generally upholding the president’s power to create, but not necessarily diminish, monuments.
Which National Monuments saw significant boundary reductions under the Trump administration?
Under the Trump administration, three national monuments saw significant boundary reductions: Bears Ears National Monument (Utah), Grand Staircase-Escalante National Monument (Utah), and Northeast Canyons and Seamounts Marine National Monument (Atlantic Ocean). These reductions were later reversed by President Biden.
Which presidents have been notable for expanding National Monuments?
Many presidents have expanded national monuments, with notable expansions occurring under Franklin D. Roosevelt, Jimmy Carter, Bill Clinton, George W. Bush (especially marine monuments), Barack Obama (e.g., Papahānaumokuākea, Pacific Remote Islands), and Joe Biden (e.g., Berryessa Snow Mountain, new designations).
What kind of sites do National Monuments protect?
National monuments protect a wide array of sites, including archaeological ruins, geological formations, historic battlefields, significant cultural landscapes, diverse ecosystems, and critical marine habitats. They preserve areas of “historic or scientific interest” for future generations.
