The Oregon slender salamander (Batrachoseps wrighti) is a species of salamander in the family Plethodontidae from the Northwestern United States. [2] [3]
The Oregon slender salamander is endemic to north-central Oregon, found particularly on the western slopes of the Cascade Range but also in some sites on the eastern slopes. [1] [3] [4]
The Oregon slender salamander is threatened by habitat loss and classified as IUCN Red List Near threatened. [1] It is federally listed as a Species of Concern. The state of Oregon has listed it as sensitive in the Oregon Conservation Strategy. [5]
The species' natural habitats are temperate forests of moist Douglas fir, maple, and red cedar woodlands in Oregon, to 910 metres (3,000 ft). [1] They are typically found in old growth habitat, associated with late-successional Douglas fir forests. However they have been found in earlier succession forest with larger logs and much downed woody debris. They are found in large diameter decayed logs. They prefer habitats that have a closed canopy. [6] The species has also been found in a suburban landscape. [7]
They have a long thin body and grow to 61 mm (2.4 in) in snout–vent length and 120 mm (4.7 in) in total length, though most individuals are smaller. They have four toes on the hind feet. [3]
Clutch size is 3–11 and the eggs are 4 mm in diameter. [3]
When found this species will coil its body up and remain motionless. [3]
Batrachoseps is a genus of lungless salamanders (plethodontids) often called slender salamanders. They can be distinguished from other lungless salamanders by the four toes they have on each foot.
The northwestern salamander is a species of mole salamander that inhabits the northwest Pacific coast of North America. These fairly large salamanders grow to 8.7 in (220 mm) in length. It is found from southeastern Alaska on May Island, through Washington and Oregon south to the mouth of the Gualala River, Sonoma County, California. It occurs from sea level to the timberline, but not east of the Cascade Divide. Its range includes Vancouver Island in British Columbia and The San Juan Islands, Cypress, Whidbey, Bainbridge, and Vashon Islands in Washington.
The California slender salamander is a lungless salamander that is found primarily in coastal mountain areas of Northern California, United States as well as in a limited part of the western foothills of the Sierra Nevada, California, in patches of the northern Central Valley of California, and in extreme southwestern Oregon. This species resides primarily in a limited range within California as one of a handful quasi-endemic amphibians in the state.
Van Dyke's salamander is a small woodland salamander in the family Plethodontidae, the lungless salamanders. These animals breathe through their skin and are largely terrestrial. Compared to other salamanders in Plethodon it is relatively stocky with long legs. Usually associated with streams, seepages, and rock outcrops, it is endemic to Washington where it is found in a limited number of small, isolated populations.
The Tarahumara salamander is a freshwater species of mole salamander in the family Ambystomatidae, endemic to Mexico. Its natural habitats are temperate forest, subtropical or tropical moist montane forest, subtropical or tropical high-altitude grassland, rivers, freshwater marshes, pastureland, and ponds.
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 Sacramento Mountain salamander is a species of salamander in the family Plethodontidae. It is endemic to mountainous regions of New Mexico in the United States. Its natural habitat is temperate forests where 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 gregarious slender salamander is a species of salamander in the family Plethodontidae. Its natural habitats are California interior chaparral and woodlands and temperate grasslands in the lower foothills of the western Sierra Nevada and the eastern Central Valley in California, United States.
The garden slender salamander is a species of salamander in the family Plethodontidae. It is found in northern Baja California in Mexico and Southern California in the United States.
The relictual slender salamander is a species of salamander in the family Plethodontidae. It is endemic to California, found only a small area in Kern County, California.
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.
Dunn's salamander is a species of salamander in the family Plethodontidae endemic to the western United States.
The Del Norte salamander is a species of salamander in the family Plethodontidae endemic to the United States in southwestern Oregon and northwestern California.
The western red-backed salamander is a species of salamander in the family Plethodontidae. The species is found in extreme southwestern Canada and the northwestern United States. The western red-backed salamander is found in temperate rainforests of the Pacific Northwest. It is considered widespread in the region and is not strictly associated with a specific habitat type.
There are 14 species of amphibians and 5 species of reptiles known to occur in Mount Rainier National Park.
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.
