What is a national monument?
National monuments are lands and waters designated for permanent protection by the federal government. They include areas of important natural, cultural, and historic resources, from geological wonders to sacred Indigenous landscapes to sites that have shaped the history of the United States.
Unlike national parks, which only Congress can designate, national monuments can either be established by the President under the authority of the 1906 Antiquities Act or by an act of Congress.
The United States has over 130 national monuments that are managed by federal agencies. While most are managed by the National Park Service, some are managed by other agencies like the US Forest Service, the US Fish and Wildlife Service, and the Bureau of Land Management.

Why are monuments important?
National monuments are protected lands, waters, or historic sites that safeguard our natural, cultural, scientific, and historic resources and legacies. They are an important tool for protecting public lands and waters for generations to come.
National monuments are also part of our response to the climate crisis. Conserving 30 percent of US lands and waters by 2030 will protect the air we breathe, water we drink, and provide a powerful climate solution. Preserving wildlands will protect vital habitats for imperiled species and save more places to connect with nature. Safeguarding places of cultural and historical significance will help honor the stories, sites, and landscapes that make us who we are.

National monuments protect geologic, marine, archaeological, and cultural sites
Protecting wild places will keep drilling and logging from polluting our air and water, and suck existing climate pollution out of the air. Creating national monuments is one of the best ways to protect public lands and preserve homes for wildlife and opportunities for people to enjoy the outdoors together.
What We Are Doing

The Sierra Club has been pivotal in the conservation and expansion of national monuments for more than a century, reflecting a broader commitment to preserving natural landscapes, combating climate change, and ensuring everyone’s history and connections to US lands are honored and celebrated.
Right now, Donald Trump, the billionaires who bought access to him, and their allies in Congress are waging an all-out assault on our parks and public lands, firing thousands of federal workers who steward these landscapes, shredding conservation protections for fragile ecosystems and places, and seeking to overturn more than a century's worth of conservation history. Their goal is to give public lands to corporate polluters and billionaires to mine, drill, log, and pollute as they please — activities that effectively block access to public lands for everyday people.
We must use every tool at our disposal, from the courts to pressuring our leaders to collective action, to stop this polluter giveaway. Every victory we've won to protect the places we hold dear has been thanks to the grassroots support of advocates like you who have written a letter, called your legislators, attended an event, posted on social media, talked to friends and family, donated, and so much more.
