Where are the Sierra Nevada foxes?
Sierra Nevada red foxes are one of three fox subspecies in the montane clade of North America, occurring in the Cascade Mountains south of the Columbia River and California 's Sierra Nevada range. Joseph Grinnell identified separated montane fox populations in the Oregon Cascades, Mount Shasta, Lassen Peak, and Sierra Nevada in 1937. Study then lapsed for approximately 60 to 75 years, depending on location. Rediscovery of the Lassen population began in 1993 followed by detection of a Sierra Nevada population at Sonora Pass in 2010 and rediscovery of the Oregon Cascades population began in 2011. The Lassen and Sonora Pass populations are isolated from each other and it is unknown if a population remains at Mount Shasta.
How long do red foxes live in Sierra Nevada?
All three phases occur in the Oregon Cascade and Sonora Pass populations, but only red phase individuals have been found in the Lassen population. Pads are fur-covered, a common adaptation to travel over snow. Sierra Nevada red foxes are long-lived relative to other red foxes, five or six years perhaps being a typical lifespan. Non-invasively monitored females have either not bred or bred a minority of years.

Why are red foxes rare in Yosemite?
The fact that Sierra Nevada red foxes eluded detection for over 100 years within Yosemite National Park is owing to their high-elevation and snow-covered habitat, extreme rarity, and avoidance of human contact.
Do red foxes have white tails?
Their bushy fox tail always has a white tip, is long and flowing and carried close to the ground where it adds an additional dimension to their length. Because of the Sierra Nevada red foxes’ snowy and bitterly cold habitat, they have beneficial adaptations that serve them well as they survive winter in the Sierra.
Where are red foxes native to?
The detections by motion sensor cameras in December 2014 and January 2015 brought to life the Sierra Nevada red fox: A most rare, elusive, and hardy creature, native to the Sierra Nevada of California, with genetic roots reaching back to the last Ice Age.
Where is the Red Fox in Yosemite?
The scientific findings confirmed the presence of the Sierra Nevada red fox in the Sonora Pass area, and created a most hopeful expectation that nearby Yosemite National Park was also the fox’s home.
When was the last time a fox was seen in Yosemite?
Last seen within Yosemite National Park boundaries in 1916, Yosemite wildlife biologists were on the lookout for the Sierra Nevada red fox after a confirmed sighting by a motion sensor camera was made at nearby Sonora Pass in 2010. The Sonora Pass detection included a bait bag with tooth punctures, which allowed University of California Davis genetics researchers to conduct a DNA analysis of saliva found on the bag. When compared to DNA extracted from Sierra Nevada red fox museum specimens collected prior to 1926, a most exciting discovery was made: the bite marks on the bait bag had the same genetic signature as the museum specimens. The scientific findings confirmed the presence of the Sierra Nevada red fox in the Sonora Pass area, and created a most hopeful expectation that nearby Yosemite National Park was also the fox’s home.

A priceless photo of a small red fox padding effortlessly atop a crest of snow in the far northern wilderness of Yosemite National Park was proof that a creature long thought extirpated in the park was indeed alive.

California prohibited trapping in 1974, and listed Sierra Nevada red fox as a threatened species in 1980. The United States Fish and Wildlife Service designated the Sonora Pass/Yosemite animals as proposed endangered species under the Endangered Species Act.
Overview
The Sierra Nevada red fox (Vulpes vulpes necator), also known as the High Sierra fox, is a subspecies of red fox found in the Oregon Cascades and the Sierra Nevada. It is likely one of the most endangered mammals in North America. The High Sierra fox shares most of its physical characteristics with the red fox, though it is slightly smaller and has some special adaptions for travel over sno…
Description
Like other montane foxes, Sierra Nevada red foxes are somewhat smaller and lighter in weight than lowland North American red foxes. Their fur may be red, cross, or silver phase with the red phase having the greyish-blonde coloration characteristic of montane foxes. All three phases occur in the Oregon Cascade and Sonora Pass populations, but only red phase individuals have been found in the Lassen population. Their foot pads are fur-covered, a common adaptation to tr…
Research
Sierra Nevada red foxes are one of three fox subspecies in the montane clade of North America, occurring in the Cascade Mountains south of the Columbia River and California's Sierra Nevada range. Joseph Grinnell identified separated montane fox populations in the Oregon Cascades, Mount Shasta, Lassen Peak, and Sierra Nevada in 1937. Study then lapsed for approximately 60 to 75 years, …
Distribution and Habitat
The extent of the Sierra Nevada red fox populations is an area of active research. In Oregon, ongoing studies at Mount Hood and Central Oregon were prompted by observations in 2012 and 2013. Recent genetic evidence also suggests range expansion into western Oregon since the 1940s. In California, detections occurred in northern Yosemite National Park the winter of 2014-15, the Stanislaus National Forest in late 2015, and in Lassen Volcanic National Park in 2018. The firs…
Diet
A 2005 study of the then remnant population surviving on Mount Lassen found that the foxes are nocturnal hunters whose diet is predominantly mammals, especially rodents and mule deer, supplemented by birds, insects and pinemat manzanita berries as seasonally available. Lagomorphs (hares, rabbits and pikas) were virtually absent from the foxes' diet.
Status and conservation
Documented trapping of the Sierra Nevada red fox may have begun when Moses Schallenberger of the Stephens-Townsend-Murphy Party spent the winter of 1844-45 at Donner Pass, taking an average of one red fox every two days. Red fox fur was sought after by trappers during the early part of the 20th century because it was softer than that of California’s gray fox (Urocyon cinereoargenteus). The St…
Origin
The three subspecies in the montane clade separated after the Wisconsin glaciation, 15 to 20,000 years ago, with the Columbia River perhaps dividing the Cascade and Sierra Nevada red foxes. However, prior to 2010, montane red foxes in Oregon were presumed to be the Cascade red fox. Earlier literature therefore indicates incorrect ranges for the Cascade and Sierra Nevada red fox.
