The National Wild and Scenic Rivers System was created by the Wild and Scenic Rivers Actof 1968, enacted by the U.S. Congress to preserve certain rivers with outstanding natural, cultural, and recreational values in a free-flowing condition for the enjoyment of present and future generations.
The Virgin River is a tributary of the Colorado River in the U.S. states of Utah, Nevada, and Arizona. The river is about 162 miles (261 km) long. It was designated Utah's first wild and scenic river in 2009, during the centennial celebration of Zion National Park.
Bidwell–Sacramento River State Park is a state park of California, United States, preserving riparian habitat on the Sacramento River and its tributary Big Chico Creek. The park is located on the border of Butte County and Glenn County. Popular activities include fishing for salmon, steelhead and shad; and floating the river on inner tubes, canoes or kayaks. The 349-acre (141 ha) property was established as a state park in 1979.
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. Organisms living in this zone are called benthos and include microorganisms as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud.
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate.
The Lower Suwannee National Wildlife Refuge (LSNWR) is part of the United States National Wildlife Refuge System. It is located in southeastern Dixie and northwestern Levy counties on the western coast of Florida, approximately fifty miles southwest of the city of Gainesville.
Upland and lowland are conditional descriptions of a plain based on elevation above sea level. In studies of the ecology of freshwater rivers, habitats are classified as upland or lowland.
The southern river otter is a species of otter that lives in Chile and Argentina. Although called a "river otter", it inhabits both marine and freshwater environments. It sometimes is considered a subspecies of Lontra canadensis. The southern river otter is listed as endangered, due to illegal hunting, water pollution, and habitat loss.
The Sebasticook River is a 76-mile-long (122 km) river in the central part of Maine, in the United States. From its source in Dexter, the upper "Main Stream" section flows generally west and south 30 miles (48 km) to Great Moose Lake. From the outlet of the lake in Hartland, the Sebasticook flows 41 miles (66 km) south to the Kennebec River in Winslow.
The Grose River, a perennial river that is part of the Hawkesbury-Nepean catchment, is located in the Blue Mountains region of New South Wales, Australia.
The survival of wild salmon relies heavily on them having suitable habitat for spawning and rearing of their young. This habitat is the main concern for conservationists everywhere. Salmon habitat can be degraded by many different factors including land development, timber harvest, or resource extraction. These threats bring about the traditional methods of protecting the salmon, but a new movement aims to protect the habitats before they require intervention.
Silvio O. Conte National Fish and Wildlife Refuge was established in 1997 to conserve, protect and enhance the abundance and diversity of native plant, fish and wildlife species and the ecosystems on which they depend throughout the 7,200,000-acre (29,000 km2) Connecticut River watershed. The watershed covers large areas of Vermont, New Hampshire, Massachusetts and Connecticut. It contains a great diversity of habitats, notably: northern forest valuable as nesting habitat for migrant thrushes, warblers and other birds; rivers and streams used by shad, salmon, herring, the endangered shortnose sturgeon and other migratory fishes; and an internationally significant complex of high-quality tidal fresh, brackish and salt marshes.
Tijuana Slough National Wildlife Refuge is located in the most southwestern corner of the contiguous United States. As a National Wildlife Refuge, it is administered by the U.S. Fish and Wildlife Service. It was established in 1980.
The San Joaquin River National Wildlife Refuge is a protected area of along the San Joaquin River in the northern San Joaquin Valley, California. It is within San Joaquin County and Stanislaus County.
Salinas River National Wildlife Refuge is located approximately 11 miles north of Monterey, California, and 3 miles south of Castroville, California, at the point where the Salinas River empties into Monterey Bay. The 367-acre (1.49 km2) refuge encompasses several habitat types including sand dunes, pickleweed salt marsh, river lagoon, riverine habitat, and a saline pond. The refuge was established in 1974 because of its "particular value in carrying out the national migratory bird management program."
Sacramento River National Wildlife Refuge is located along the Sacramento River in the Sacramento Valley of California. Landscape is very flat, bordered by the Sierra and Coast ranges, with intensive agriculture. This riparian community is one of the most important wildlife habitats in California and North America.
The De Lank River is a small river in north Cornwall, England. It is a tributary of the River Camel and is approximately nine miles (14.5 km) long from its source on Bodmin Moor to its confluence with the Camel two miles (3 km) south of St Breward.
Totaling 4,362 acres (17.65 km2), this area is the largest, highest quality estuarine system remaining in Washington or Oregon. It includes diverse habitats, ranging from tideflats and sloughs, saltmarsh and freshwater wetlands, to forested uplands.
Marine habitats are habitats that support marine life. Marine life depends in some way on the saltwater that is in the sea. A habitat is an ecological or environmental area inhabited by one or more living species. The marine environment supports many kinds of these habitats. Marine habitats can be divided into coastal and open ocean habitats. Coastal habitats are found in the area that extends from as far as the tide comes in on the shoreline out to the edge of the continental shelf. Most marine life is found in coastal habitats, even though the shelf area occupies only seven percent of the total ocean area. Open ocean habitats are found in the deep ocean beyond the edge of the continental shelf.
Omineca Provincial Park and Protected Area is a provincial park and protected area located in the north-central interior of British Columbia, Canada. It was established on 11 April 2001 by BC Parks to protect provincially significant riparian and wetland habitats along the Omineca River.
