What to know about Trump shrinking 2 national monuments in Utah

Key Points:

• President Donald Trump announced plans to significantly reduce the size of Utah's Bears Ears and Grand Staircase-Escalante national monuments, reversing protections established by previous administrations and reinstated by President Joe Biden.
• The reductions shrink the combined area from over 3.2 million acres to less than 303,000 acres, aiming to open land for mining and state management, a move supported by Utah officials but opposed by conservationists and Native American tribes.
• The Antiquities Act of 1906 grants presidents authority to create and modify national monuments, and historically, several presidents, including Woodrow Wilson and Dwight Eisenhower, have reduced monument boundaries.
• National monuments differ from national parks in that they are primarily designated by presidential proclamation and are managed by various federal agencies, offering protections against development and resource extraction, whereas national parks are established by Congress with stricter conservation rules.
• Since its inception by President Theodore Roosevelt in 1906, the Antiquities Act has been widely used by presidents to protect culturally and scientifically significant sites, making monument designation a long-standing tool for preserving public lands.
