Kobuk Valley National Park is an American national park in the Arctic region of northwestern Alaska, located about 25 miles (40 km) north of the Arctic Circle. The park was designated in 1980 by the Alaska National Interest Lands Conservation Act to preserve the 100 ft (30 m) high Great Kobuk Sand Dunes and the surrounding area which includes caribou migration routes. Park visitors must bring all their own gear for backcountry camping, hiking, backpacking, boating, and dog sledding. No designated trails or roads exist in the park, which at 1,750,716 acres, is slightly larger than the state of Delaware. Kobuk Valley is one of eight national parks in Alaska, the state with the second most national parks, surpassed only by California which has nine. The park is managed by the National Park Service.
The Kodiak National Wildlife Refuge is a United States National Wildlife Refuge in the Kodiak Archipelago in southwestern Alaska, United States.
The Yukon Delta National Wildlife Refuge is a United States National Wildlife Refuge covering about 19.16 million acres (77,500 km2) in southwestern Alaska. It is the second-largest National Wildlife Refuge in the country, only slightly smaller than the Arctic National Wildlife Refuge.

The Dungeness National Wildlife Refuge is located near the town of Sequim in Clallam County in the U.S. state of Washington, on the Strait of Juan de Fuca. The refuge is composed of 772.52 acres (312.63 ha) which include Dungeness Spit, Graveyard Spit, and portions of Dungeness Bay and Harbor. Dungeness Spit is one of the world's longest natural sand spits, 6.8 miles (10.9 km) long and very narrow. A lighthouse, the New Dungeness Light, built in 1857, is located near the end of the spit. Access to Dungeness Spit is through a Clallam County Park which has hiking trails, picnic areas, and a campground. On January 20, 1915, it was designated as a National Wildlife Refuge by President Woodrow Wilson.
Alaska is one of two U.S. states not bordered by another state; Hawaii the other. Alaska has more ocean coastline than all of the other U.S. states combined. About 500 miles (800 km) of Canadian territory separate Alaska from Washington State. Alaska is thus an exclave of the United States that is part of the continental U.S. and the U.S. West Coast, but is not part of the contiguous U.S. Alaska is also the only state, other than Hawaii, whose capital city is accessible only via ship or air, because no roads connect Juneau to the rest of the continent.
The environment of the United States comprises diverse biotas, climates, and geologies. Environmental regulations and the environmental movement have emerged to respond to the various threats to the environment.
Togiak Wilderness is a federally designated wilderness area in the Dillingham and Bethel Census Areas in the southwestern part of the U.S. state of Alaska. At 2,274,066 acres (920,282 ha), it occupies the northern half of the Togiak National Wildlife Refuge. It protects pristine rivers, lakes, and steep-sloped mountains, including the rugged Ahklun Mountains and Wood River Range, which are located partly within the wilderness. Parts of the Kanektok, Goodnews, and Togiak drainages are also located within the boundaries of the Togiak Wilderness.
The Izembek National Wildlife Refuge is the smallest of the National Wildlife Refuges located in the U.S. state of Alaska. It lies on the northwest coastal side of central Aleutians East Borough. Most of the refuge was designated as Wilderness in 1980 under the Alaska National Interest Lands Conservation Act. The refuge is administered from offices in Cold Bay.
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 km2), 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.
Kanuti National Wildlife Refuge is a national wildlife refuge in central Alaska, United States. One of 16 refuges in Alaska, it was established in 1980 when Congress passed The Alaska National Interest Lands Conservation Act (ANILCA). At 1,640,000 acres (6,600 km2), Kanuti Refuge is about the size of the state of Delaware. Located at the Arctic Circle, the refuge is a prime example of Alaska's boreal ecosystem. It is dominated by black and white spruce, with some white birch and poplars.
The Koyukuk National Wildlife Refuge is a 3,500,000-acre (14,000 km2) conservation area in Alaska. It lies within the floodplain of the Koyukuk River, in a basin that extends from the Yukon River to the Purcell Mountains and the foothills of the Brooks Range. This region of wetlands is home to fish, waterfowl, beaver and Alaskan moose, and wooded lowlands where two species of fox, bears, wolf packs, Canadian lynx and marten prowl.
The heart of Nowitna National Wildlife Refuge is a lowland basin of forests and wetlands that forms the floodplain of the meandering Nowitna River. The refuge's climate is typically marked by light precipitation, mild winds, long, hard winters and short, relatively warm, summers. The hills that circle the refuge lowlands are capped by alpine tundra.
Tetlin National Wildlife Refuge is a dynamic landscape made up of forests, wetlands, tundra, lakes, mountains and glacial rivers bounded by the snowy peaks of the Alaska Range. This upper Tanana River valley has been called the "Tetlin Passage," because it serves as a major migratory route for birds traveling to and from Canada, the lower 48 and both Central and South America. Many of these birds breed and nest on the refuge. Others pass through on their way to breeding and nesting grounds elsewhere in the state. Migrants, including ducks, geese, swans, cranes, raptors and songbirds, begin arriving in the valley in April, and continue into early June. An estimated 116 species breed on Tetlin during the short summer, when long days and warm temperatures accelerate the growth of plants, insects and other invertebrates, providing a ready source of rich foods for nesting birds.
Grays Lake National Wildlife Refuge is a National Wildlife Refuge of the United States located in southeastern Idaho. It has the largest hardstem bulrush marsh in North America. Located in a high mountain valley near Soda Springs, the refuge and surrounding mountains offer scenic vistas, wildflowers, and fall foliage displays. Lands adjacent to the 19,400-acre (79 km2) refuge are primarily wet meadows and grasslands. The refuge provides breeding habitat for species of mammals including moose, elk, mule deer, muskrat, badger, and weasel.
Humboldt Bay National Wildlife Refuge is located on Humboldt Bay, on the California North Coast near the cities of Eureka and Arcata. The refuge exists primarily to protect and enhance wetland habitats for migratory water birds using the bay area, including tens of thousands of shorebirds, ducks, geese, swans, and the black brant. Humboldt Bay National Wildlife Refuge, along with other public and private lands around Humboldt Bay, is one of the key stopovers for the millions of migratory birds that rely on the Pacific Flyway. More than 200 bird species, including 80 kinds of water birds and four endangered species, regularly feed, rest, or nest on the refuge or other areas around the bay.
The Beringia upland tundra is a mountainous tundra ecoregion of North America, on the west coast of Alaska.
The fauna of the State of California may be the most diverse in the United States of America. Of the Lower 48 conterminous states, California has the greatest diversity in climate, terrain and geology in general. The state's six life zones are the lower Sonoran (desert); upper Sonoran ; transition ; and the Canadian, Hudsonian, and Arctic zones, comprising California's highest elevations. California’s diverse geography gives rise to dozens of different ecosystems, each of which has its own unique native plants and animals. California is a huge state, the 3rd largest in the U.S., and can range broadly in habitat type.
