The National Park Service (NPS) is an agency of the United States federal government, within the U.S. Department of the Interior. The service manages all national parks; most national monuments; and other natural, historical, and recreational properties, with various title designations. The United States Congress created the agency on August 25, 1916, through the National Park Service Organic Act. Its headquarters are in Washington, D.C., within the main headquarters of the Department of the Interior.
The Grand Staircase–Escalante National Monument (GSENM) is a United States national monument protecting the Grand Staircase, the Kaiparowits Plateau, and the Canyons of the Escalante in southern Utah. It was established in 1996 by President Bill Clinton under the authority of the Antiquities Act with 1.7 million acres of land, later expanded to 1,880,461 acres (7,610 km2). In 2017, the monument's size was reduced by half in a succeeding presidential proclamation, and it was restored in 2021. The land is among the most remote in the country; it was the last to be mapped in the contiguous United States.
In the United States, a national monument is a protected area that can be created from any land owned or controlled by the federal government by proclamation of the president of the United States or an act of Congress. National monuments protect a wide variety of natural and historic resources, including sites of geologic, marine, archaeological, and cultural importance. In contrast, national parks in the U.S. must be created by Congressional legislation. Some national monuments were first created by presidential action and later designated as national parks by congressional approval.
Pinnacles National Park is an American national park protecting a mountainous area located east of the Salinas Valley in Central California, about five miles (8 km) east of Soledad and 80 miles (130 km) southeast of San Jose. The park's namesakes are the eroded leftovers of the western half of an extinct volcano that has moved 200 miles (320 km) from its original location on the San Andreas Fault, embedded in a portion of the California Pacific Coast Ranges. Pinnacles is managed by the National Park Service and the majority of the park is protected as wilderness.
In all modern states, a portion of land is held by central or local governments. This is called public land, state land, or Crown land. The system of tenure of public land, and the terminology used, varies between countries. The following examples illustrate some of the range.
The Alaska National Interest Lands Conservation Act (ANILCA) is a United States federal law signed by President Jimmy Carter on December 2, 1980. ANILCA provided varying degrees of special protection to over 157,000,000 acres (64,000,000 ha) of land, including national parks, national wildlife refuges, national monuments, wild and scenic rivers, recreational areas, national forests, and conservation areas. It was, and remains to date, the single largest expansion of protected lands in history and more than doubled the size of the National Park System.

The Wilderness Society also engages in a number of ancillary activities, including education and outreach, and hosts one of the most valuable collections of Ansel Adams photographs at their headquarters in Washington, D.C.

Conservation in the United States can be traced back to the 19th century with the formation of the first National Park. Conservation generally refers to the act of consciously and efficiently using land and/or its natural resources. This can be in the form of setting aside tracts of land for protection from hunting or urban development, or it can take the form of using less resources such as metal, water, or coal. Usually, this process of conservation occurs through or after legislation on local or national levels is passed.
The Northeast Canyons and Seamounts Marine National Monument is a marine national monument of the United States off the coast of New England, on the seaward edge of Georges Bank.

The Native American names for the buttes have the same meaning in each of the languages represented in the region. The names are listed in the presidential proclamation as "Hoon’Naqvut, Shash Jáa [sic], Kwiyaghatʉ Nükavachi/Kwiyagatu Nukavachi, Ansh An Lashokdiwe"—all four mean "Bears Ears".

Twenty-two land monuments and five marine monuments that were created by the administrations of Bill Clinton, George W. Bush, and Barack Obama were subject to review.
The John D. Dingell Jr. Conservation, Management, and Recreation Act of 2019 is an omnibus lands act that protected public lands and modified management provisions. The bill designated more than 1,300,000 acres (5,300 km2) of wilderness area, expanded several national parks and other areas of the National Park System, and established four new national monuments while redesignating others. Other provisions included making the Land and Water Conservation Fund permanent, protecting a number of rivers and historic sites, and withdrawing land near Yellowstone National Park and North Cascades National Park from mining.
Massachusetts Lobstermen's Association v. Ross is a United States District Court case in the District of Columbia in which the court determined whether or not a President may establish a marine national monument, the Northeast Canyons and Seamounts Marine National Monument, under the authority of the Antiquities Act of 1906. The case represents the first time that the President's authority to create an offshore marine monument under the Act was directly challenged in court. While the District Court upheld the President's authority to designate the monument under the authority bestowed by the Antiquities Act, the case was appealed to the D.C. Circuit and awaits further judicial review.
