National Wilderness Preservation System in the context of Paria Canyon-Vermilion Cliffs Wilderness

Becharof National Wildlife Refuge is a National Wildlife Refuge in the Aleutian Range of the Alaska Peninsula of southwestern Alaska. It is adjacent to Katmai National Park and Preserve. This national wildlife refuge, which covers an area of 1,200,000 acres (4,900 km), was established in 1980 to conserve major brown bears, salmon, migratory birds, caribou, marine birds, and mammals and to comply with treaty obligations. It lies primarily in the east-central part of Lake and Peninsula Borough, but extends eastward into the mainland portion of Kodiak Island Borough. The refuge is administered from offices in King Salmon.

Becharof Wilderness it comprises approximately 500,000 acres (2,000 km) and is bordered by the Katmai Wilderness on the north. It was designated a wilderness area in 1980 by the Alaska National Interest Lands Conservation Act.

Yosemite National Park (/joʊˈsɛmɪti/ yoh-SEM-ih-tee) is a national park of the United States in California. It is bordered on the southeast by the Sierra National Forest and on the northwest by Stanislaus National Forest. The park is managed by the National Park Service and covers 1,187 sq mi (3,070 km) in four counties – centered in Tuolumne and Mariposa, extending north and east to Mono and south to Madera. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its granite cliffs, waterfalls, clear streams, groves of giant sequoia, lakes, mountains, meadows, glaciers, and biological diversity. Almost 95 percent of the park is designated wilderness. Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada mountain range.

Its geology is characterized by granite and remnants of older rock. About 10 million years ago, the Sierra Nevada was uplifted and tilted to form its unique slopes, which increased the steepness of stream and river beds, forming deep, narrow canyons. About one million years ago, glaciers formed at higher elevations. They moved downslope, cutting and sculpting the U-shaped Yosemite Valley.

Kings Canyon National Park is a national park of the United States in the southern Sierra Nevada, in Fresno and Tulare Counties, California. Originally established in 1890 as General Grant National Park, the park was greatly expanded and renamed on March 4, 1940. The park's namesake, Kings Canyon, is a rugged glacier-carved valley more than a mile (1,600 m) deep. Other natural features include multiple 14,000-foot (4,300 m) peaks, high mountain meadows, swift-flowing rivers, and some of the world's largest stands of giant sequoia trees. Kings Canyon is north of and contiguous with Sequoia National Park, and both parks are jointly administered by the National Park Service as the Sequoia and Kings Canyon National Parks.

The majority of the 461,901-acre (186,925 ha) park, drained by the Middle and South Forks of the Kings River and many smaller streams, is designated wilderness. Tourist facilities are concentrated in two areas: Grant Grove, home to General Grant (the second largest tree in the world, measured by trunk volume) and Cedar Grove, located in the heart of Kings Canyon. Overnight hiking is required to access most of the park's backcountry, or high country, which for much of the year is covered in deep snow. The combined Pacific Crest Trail/John Muir Trail, a backpacking route, traverses the entire length of the park from north to south.

Innoko Wilderness is a 1,240,000-acre (500,000 ha) wilderness area in the U.S. state of Alaska. It was designated by the United States Congress in 1980. It lies within the southeastern part of Innoko National Wildlife Refuge. Innoko Wilderness is a transition zone between the boreal forestland of interior Alaska and the open tundra of western Alaska. More than half of the Wilderness is wetlands of muskeg and marsh, lakes, rivers, and streams dotted with islands of black spruce and an understory of mosses, lichens, and shrubs. Along the Yukon and Innoko Rivers are numerous privately owned subsistence camps used periodically for hunting and fishing by Alaska Natives.

The Black Rock Desert–High Rock Canyon Emigrant Trails National Conservation Area is the federal land in northwestern Nevada, under the Bureau of Land Management-BLM management and protection, and the ten Wilderness Areas within it.

The long name has led people to often shorten it to the Black Rock–High Rock NCA, when not needing the official name. The protected areas were created by the Black Rock Desert–High Rock Canyon Emigrant Trails National Conservation Area Act of 2000.

The Middle Fork Kings River is a 37.2-mile (59.9 km) tributary of the Kings River in Kings Canyon National Park, California, in the southern Sierra Nevada. Draining 318 square miles (820 km) – almost all of it wilderness – the Middle Fork is one of the largest wholly undeveloped watersheds in the state, with no dams or paved roads within its basin. The entire length of the Middle Fork is designated a National Wild and Scenic River.

The United States has ten protected areas known as national seashores and three known as national lakeshores, which are public lands operated by the National Park Service (NPS), an agency of the Department of the Interior. National seashores and lakeshores are coastal areas federally designated by Congress as being of natural and recreational significance as a preserved area. All of the national lakeshores are on Lakes Michigan and Superior, and nine of the ten national seashores are on the Atlantic Ocean, including two on the Gulf of Mexico. Point Reyes is the only national seashore on the Pacific coast. While all of these protected sites have extensive beaches for recreation, they extend inland to include other natural resources like wetlands and marshes, forests, lakes and lagoons, and dunes. Many also feature historic lighthouses and estates.

National seashores are located in ten states and national lakeshores are in two other states. Florida, North Carolina, and Michigan each have two. The largest national seashore or lakeshore is Gulf Islands, at over 137,000 acres (550 km); the smallest is Fire Island, at 19,579 acres (79.23 km). The total areas protected by national seashores and lakeshores are approximately 595,000 acres (2,410 km) and 214,000 acres (870 km), respectively. These thirteen sites had a total visitation of 21.1 million people in 2017, led by Cape Cod at over 4 million visitors. The lakeshores and seashores have an emphasis on recreation, and most allow hunting and off-road vehicles, which is not permitted in national parks. Five seashores and lakeshores also include land more strictly protected as wilderness areas.

Joshua Tree National Park is a US National Park located in southeastern California, straddling north-central Riverside County and part of southern San Bernardino County. Named after the endemic Joshua tree (Yucca brevifolia), found in the park and surrounding areas, Joshua Tree is situated some 130 miles (211 km) east of the city of Los Angeles and roughly 78 mi (125 km) east of the city of San Bernardino. Among some of the closest cities to the park are Indio, Palm Desert, and Palm Springs. Originally declared a national monument in 1936, Joshua Tree was redesignated as a national park in 1994 when the U.S. Congress passed the California Desert Protection Act.

Encompassing a total area of 795,156 acres (1,242.4 sq mi; 3,217.9 km)—slightly larger than the state of Rhode Island—the park features 429,690 acres (671.4 sq mi; 1,738.9 km) of designated wilderness. The park encompasses portions of two deserts, each a unique ecosystem with characteristics determined primarily by elevation—the higher Mojave Desert and the lower-lying Colorado Desert. The Little San Bernardino Mountains line the park's southwest edge.

North Cascades National Park is a national park of the United States in Washington. At more than 500,000 acres (200,000 ha), it is the largest of the three National Park Service units that comprise the North Cascades National Park Complex. North Cascades National Park consists of a northern and southern section, bisected by the Skagit River that flows through the reservoirs of Ross Lake National Recreation Area. Lake Chelan National Recreation Area lies on the southern border of the south unit of the park. In addition to the two national recreation areas, other protected lands including several national forests and wilderness areas, as well as Canadian provincial parks in British Columbia, nearly surround the park. North Cascades National Park features the rugged mountain peaks of the North Cascades Range, the most expansive glacial system in the contiguous United States, the headwaters of numerous waterways, and vast forests with the highest degree of flora biodiversity of any American national park.

The region was first settled by Paleo-Indian Native Americans; by the time European American explorers arrived, it was inhabited by Skagit tribes. By the early 19th century, the region was visited by fur trappers and several British and American companies vied for control over the fur trade. After the Canada–United States border was set at the 49th parallel in 1846, explorers came to chart potential routes through the mountains for roads and railroads. Limited mining and logging occurred from the late 19th century to the early 20th century. The first significant human impact in the region occurred in the 1920s when several dams were built in the Skagit River valley to generate hydroelectric power. Environmentalists then campaigned to preserve the remaining wilderness, culminating on October 2, 1968, with the designation of North Cascades National Park.

The Cibola National Forest (pronounced SEE-bo-lah) is a 1,633,783 acre (6,611.7 km2) United States National Forest in New Mexico, US. The name Cibola is thought to be the original Zuni Indian name for their pueblos or tribal lands. The name was later interpreted by the Spanish to mean "buffalo". The forest is disjointed with lands spread across central and northern New Mexico, west Texas and Oklahoma. The Cibola National Forest is divided into four Ranger Districts: the Sandia, Mountainair, Mt. Taylor, and Magdalena. The Forest includes the San Mateo, Magdalena, Datil, Bear, Gallina, Manzano, Sandia, Mt. Taylor, and Zuni Mountains of west-central New Mexico. The Forest also manages four National Grasslands that stretch from northeastern New Mexico eastward into the Texas Panhandle and western Oklahoma. The Cibola National Forest and Grassland is administered by Region 3 of the United States Forest Service from offices in Albuquerque, New Mexico. Elevation ranges from 5,000 ft (1,500 m) to 11,301 ft (3,445 m). (The preceding figures do not include any of the four National Grasslands mentioned below, which are detailed in their individual articles.) The descending order of Cibola National Forest acres (not counting the three Grassland areas) by county are: Socorro, Cibola, McKinley, Catron, Torrance, Bernalillo, Sandoval County, New Mexico, Lincoln, Sierra, and Valencia counties in New Mexico. The Cibola National Forest currently has 137,701 acres designated as Wilderness. In addition to these acres, it has 246,000 acres classified as Inventoried Roadless Areas pursuant to the Roadless Area Conservation Rule.

The Cibola National Forest is organized into several divisions over three states. The Rita Blanca National Grassland 92,989 acres (376.3 km) in Dallam County, Texas, and Cimarron County, Oklahoma, Black Kettle National Grassland 31,286 acres (126.6 km) in Roger Mills County, Oklahoma, and Hemphill County, Texas, and McClellan Creek National Grassland 1,449 acres (5.9 km) in Gray County, Texas, are in the Oklahoma–Texas panhandle region. The combined Cibola National Grasslands are 262,141 acres (1,060.8 km2) in size.

The Chequamegon–Nicolet National Forest (/ʃɪˈwɑːmɪɡən ˌnɪkəˈleɪ/; the q is silent) is a 1,530,647-acre (6,194.31 km) U.S. National Forest in northern Wisconsin in the United States. Legally two separate national forests—the Chequamegon National Forest and the Nicolet National Forest—the areas were established by presidential proclamations in 1933 and have been managed as one unit since 1998. The national forest land trees and vegetation are part of the North Woods ecoregion that prevails throughout the upper Great Lakes region. Little old-growth forest remains due to logging in the early part of the 20th century, and some of the second-growth forest was planted by the Civilian Conservation Corps in the 1930s.

The Chequamegon National Forest comprises three units in the north-central part of the state totaling 865,825 acres (3,503.87 km). In descending order of forestland area, it is located in parts of Bayfield, Ashland, Price, Sawyer, Taylor, and Vilas counties. Forest headquarters are in Park Falls. There are local ranger district offices in Glidden, Hayward, Medford, Park Falls, and Washburn. Moquah Barrens Research Natural Area is located with the Chequamegon. Lying within the Chequamegon are two officially designated wilderness areas of the National Wilderness Preservation System. These are the Porcupine Lake Wilderness and the Rainbow Lake Wilderness.

The United States has 154 protected areas known as national forests, covering 188,336,179 acres (762,169 km; 294,275 sq mi). National forests are managed by the U.S. Forest Service, an agency of the U.S. Department of Agriculture. The first national forest was established as the Yellowstone Park Timber and Land Reserve on March 30, 1891, then in the Department of the Interior. In 1897, the Organic Act provided purposes for which forest reserves could be established, including to reserve a supply of timber, protect the forest from development, and secure water supplies. With the Forest Reserve Act of 1891, the president of the United States is given the power to set aside forest reserves in the public domain. With the Transfer Act of 1905, forest reserves became part of the U.S. Department of Agriculture in the newly created U.S. Forest Service.

By 1907, President Theodore Roosevelt had more than doubled the forest-reserve acreage, and Congress responded by limiting the president's ability to proclaim new reserves. The National Forest System underwent a major reorganization in 1908, and in 1911 Congress authorized new additions to the system under the authority of the Weeks Act. The management goals provided by the Organic Act were expanded upon by the Multiple-Use Sustained-Yield Act of 1960 to include "outdoor recreation, range, timber, watershed, and wildlife and fish purposes" as well as for the establishment of wilderness areas.

A wilderness study area (WSA) contains undeveloped United States federal land retaining its primeval character and influence, without permanent improvements or human habitation, and managed to preserve its natural conditions. The Bureau of Land Management (BLM) manages wilderness study areas under the National Landscape Conservation System to protect their value as wilderness until Congress decides whether to designate them as wilderness, including them in the National Wilderness Preservation System.

On BLM lands, a WSA is a roadless area that has been inventoried (but not designated by Congress) and found to have wilderness characteristics as described in Section 603 of the Federal Land Policy and Management Act of 1976 and Section 2(c) of the Wilderness Act of 1964. Wilderness Study Area characteristics are:

Mount Baker Wilderness is a 119,989-acre (48,558 ha) wilderness area within the Mount Baker-Snoqualmie National Forest in the western Cascade Range of northern Washington state. Its eastern border is shared with the boundary of the Stephen Mather Wilderness and North Cascades National Park for a distance of 40 miles (65 kilometers). The wilderness extends from State Route 20 north to the Canada–US border. On the west, it is bounded by the foothills of the Puget Sound lowlands.

Almost entirely within Whatcom County, the wilderness lies on the western slopes of the Cascade Mountains. The three forks of the Nooksack River and the Baker River are the major drainages of the wilderness.

The Baboquivari Peak Wilderness or La Bestia is a 2,065-acre (8 km) wilderness area in the U.S. state of Arizona. It is located in the Baboquivari Mountains 50 miles (80 km) southwest of Tucson, Arizona. It is administered by the Bureau of Land Management and co-stewarded by the Tohono O'odham Nation. The United States Congress designated the Baboquivari Peak Wilderness in 1990. It is the smallest such designated wilderness in the state of Arizona. Today, the 2,900,000-acre (12,000 km) Tohono Oʼodham Nation (second largest reservation in the United States) lies to the west. Baboquivari Peak's elevation is 7,730 feet (2,356 m). It is a popular site for many climbers, tourists and other visitors to Arizona and can be seen in the distance from the Kitt Peak National Observatory in the Quinlan Mountain Range.

Baboquivari Peak is a technical summit, meaning that it is only accessible by technical (class 5) rock climbing according to the Yosemite Decimal System. The wilderness is reported to have some of the best backcountry rock climbing in Arizona. It can be visited any time of the year; however, outside visitors who are not members of the Tohono O'odham nation, must first procure a permit to be on the reservation. Also, summer afternoons are usually too hot for hiking, and winter can bring an occasional snow shower to the peak's highest elevations. Sightings of jaguars have been recorded in the Baboquivaris during the last decades.
