Wetlands in the Sierra Nevada occur in valley bottoms throughout the range, and are often hydrologically linked to nearby lakes and rivers through seasonal flooding and groundwater movement. Meadow habitats , distributed at elevations from 3,000 to 11,000 feet (910 to 3,350 m), are generally wetlands, as are the riparian habitats found on the ...
Sierra Nevada bighorn sheep inhabit portions of the Sierra Nevada located along the eastern boundary of California in Tuolumne, Mono, Fresno, Inyo, and Tulare Counties. Habitat occurs from the eastern base of the range as low as 4,790 feet (1,460 m) to peaks above 14,100 feet (4,300 m).
Melanistic Sierra Nevada red fox. The extent of the Sierra Nevada red fox populations is an area of active research. In Oregon, ongoing studies at Mount Hood [15] and Central Oregon [16] [17] were prompted by observations in 2012 and 2013. Recent genetic evidence also suggests range expansion into western Oregon since the 1940s. [18]
The Sierra Nevada yellow-legged frog or Sierra Nevada Mountain yellow-legged frog (Rana sierrae) is a true frog endemic to the Sierra Nevada of California and Nevada in the United States. It was formerly considered Rana muscosa until a 2007 study elevated the more central and northern populations to full species status, restricting R. muscosa ...
The frog is represented in the Sierra Nevada by three or four populations. [1] Its decline is attributed to many factors, including introduced species of fish such as trout, livestock grazing, [11] chytrid fungus, [12] and probably pesticides, drought, and ultraviolet radiation. [11] Recreational activities in streams have also had an impact. [13]
The Sierra Nevada, also known locally as the "Sierra", is a mountain range running 400 miles (640 km) north-to-south along eastern California, and occasionally into western Nevada. The name "Sierra Nevada" is Spanish, translating as "Snowy (Mountain) Range".
The Sierra Nevada subalpine zone occurs between 2,450–3,660 metres (8,000–12,000 ft), and is characterized by an open woodland of several conifer species, including whitebark pine, lodgepole pine, western white pine, mountain hemlock, and Sierra juniper. The vegetation and ecology is determined by the harsh climate, with extensive snow and ...
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range in the western United States.The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey.
