The Appalachian Mountains, often called the Appalachians, are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west.
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment, and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats.
The New River Gorge National Park and Preserve is a unit of the United States National Park Service (NPS) designed to protect and maintain the New River Gorge in southern West Virginia in the Appalachian Mountains. Established in 1978 as a national river and redesignated in 2020, the park and preserve stretches for 53 miles (85 km) from just downstream of Hinton to Hawks Nest State Park near Ansted.
Chimney Rock State Park is a North Carolina state park in Chimney Rock, Rutherford County, North Carolina in the United States. The 8,014-acre (32.43 km2) park is located 25 miles (40 km) southeast of Asheville, North Carolina, and is owned and managed by the state of North Carolina.
The Appalachian–Blue Ridge forests are an ecoregion in the Temperate broadleaf and mixed forests Biome, in the Eastern United States. The ecoregion is located in the central and southern Appalachian Mountains, including the Ridge-and-Valley Appalachians and the Blue Ridge Mountains. It covers an area of about 61,500 square miles (159,000 km2) in: northeast Alabama and Georgia, northwest South Carolina, eastern Tennessee, western North Carolina, Virginia, Maryland, and central West Virginia and Pennsylvania; and small extensions into Kentucky, New Jersey, and New York.
Climbing salamanders is the common name for plethodontid (lungless) salamanders of the genus Aneides. It contains 10 species native to North America, distributed between the Pacific Coast, Sacramento Mountains, and Appalachian Mountains. As their common name suggests, most of these species have prehensile tails and are quite mobile in trees.
The striped newt is a species of aquatic salamander native to the southeastern United States. It is a close relative of the eastern newt, with which it shares territory, and can be distinguished from the latter by the presence of red stripes running down the sides of its back and red spots on its back that lack a black outline.
The Cheat Mountain salamander is a species of small woodland salamander found only on Cheat Mountain, and a few nearby mountains, in the eastern highlands of West Virginia. It and the West Virginia spring salamander are the only vertebrate species with geographic ranges restricted to that state.
The clouded salamander is a species of salamander in the family Plethodontidae. It is endemic to the Pacific Northwest. Its natural habitat is temperate forests and it is probable that many nest in trees. It is threatened by habitat loss.
The speckledblack salamander, previously known as just the black salamander, is a species of salamander in the family Plethodontidae. It is endemic to the U.S. state of California. Its natural habitats are temperate forests and temperate grassland. It is threatened by habitat loss.
The wandering salamander is a species of salamander in the family Plethodontidae. It has a disjunct distribution, with one population being found in northern California in the United States, and another in British Columbia, Canada. It is a matter of debate whether this distribution is the result of human introductions or whether it has natural origins, with the latter conclusion being supported by more evidence. Its natural habitat is temperate forests. It is threatened by habitat loss from logging.
The ocoee salamander is a species of salamander in the family Plethodontidae. This salamander has a variety of colors and patterns, and got its name from Tennessee state wildflower. Its natural habitats are temperate forests, rivers, intermittent rivers, freshwater springs and wet rocks in mountainous areas of the Southeastern United States. It was first described by Nicholls in 1949. They are territorial and feed on small invertebrates. It is widely distributed in the southeastern United States and is listed as "Least Concern" by the International Union for Conservation of Nature.
The pygmy salamander is a species of salamander in the family Plethodontidae. It is endemic to the United States in the southern Appalachians in North Carolina and Tennessee. Desmognathus wrighti is a member of the family Plethodontidae and is commonly known as the pygmy salamander. As the name suggest the pygmy salamander is the smallest of the nineteen species in the genus Desmognathus. D. wrighti undergoes direct development and does not have a free-living larval stage. Only two other taxa in Desmognathus, D. aeneus and D. organi, exhibit direct development along with the pygmy salamander. In the genus Desmognathus, body size, habitat preferences, and patterns used by males during courtship are quite variable. D. wrighti courtship is noted by the male biting and seizing its partner in order to provide them with a chemical stimulus. The pygmy salamander can be found in the southern Appalachians of the United States in western North Carolina and eastern Tennessee. Geographical distribution of the Desmognathus wrighti is fragmented and the highest abundance of the species can be found at high elevations in spruce and fir tree forest.
The Webster's salamander is a species of salamander in the family Plethodontidae. It is endemic to the southeast United States, in patchy and disjunct lowland subpopulations ranging from South Carolina to Louisiana. Its natural habitat is mixed mesophytic temperate forests, in association with rocky streams and outcrops.
The green salamander is a species of lungless salamander in the family Plethodontidae. It and the Hickory Nut Gorge green salamander are the only currently-described members of the genus Aneides that inhabit any areas in the eastern half of United States. Rarely seen in the field, the green salamander is an extremely habitat-specific species that is seldom found away from its preferred surroundings: moist, shaded rock crevices.
In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch. Similarly, a relictual taxon is a taxon which is the sole surviving representative of a formerly diverse group.
The eastern tree hyrax is a species of mammal within the family Procaviidae. The eastern tree hyrax is the most localized of the tree hyrax species, distributed patchily in a narrow band of lowland and montane forests in Kenya and Tanzania and adjacent islands.
Hickory Flats is an area in the George Washington and Jefferson National Forests of western Virginia that has been recognized by the Wilderness Society as a special place worthy of protection from logging and road construction. It is in a remote location at the headwaters of two streams with a wetland that contains rare plants and provides an unusual habitat for wildlife.
The northern pygmy salamander is a terrestrial species of salamander in the family Plethodontidae and genus Desmognathus. Along with the southern pygmy and the seepage salamander, these are some of the smallest salamander species in North America and can be found in higher elevations in the southern Appalachians.
