The Sierra Nevada red fox is the only red fox that occurs naturally in the high mountain habitats of the Sierra Nevada and southern Cascade mountains of eastern California. A gestation period of 51-53 days. Sierra Nevada Red Fox Ecology The Sierra Nevada red fox (SNRF; Vulpes vulpes necator) historically occurred throughout the Pacific Crest Ranges of California and Oregon.During the 20th Century, SNRF populations in California declined precipitously. During the 20th Century, SNRF populations in California declined precipitously. [23] The first two areas are near Sonora Pass, but it has not been confirmed the individuals are part of the Sonora Pass population. The tiny kit fox population way down in the far reaches of SE Oregon is mentioned, along with the alien eastern red fox and native common gray fox, but somehow, the authors missed the Sierra Nevada red fox that's been found throughout the Oregon Cascades for a long time. [19] In California, detections occurred in northern Yosemite National Park the winter of 2014-15,[20][21] the Stanislaus National Forest in late 2015,[22] and in Lassen Volcanic National Park in 2018. The extent of the Sierra Nevada red fox populations is an area of active research. In fact, Hiller said past and ongoing research in Oregon suggests that SNRF, while still rare, may be more widespread than originally thought. Undocumented in state until recently, Sierra Nevada red fox is showing up on camera. Within the Strategy, ODFW identified data gaps associated with this rare montane (mountain) fox, including assessing population dynamics, collecting genetic information, understanding seasonal habitat use, and evaluating competition from coyotes. In the first week of May, biologists from the Oregon Department of Fish and Wildlife and the Wildlife Ecology Institute discovered an extremely rare species of Sierra Nevada red fox in Deschutes County near Bend, Oregon. The Sierra Nevada red fox has been added as a “strategy species” in the 2015 draft update of the Oregon Conservation Strategy after ongoing studies found … Sierra Nevada red fox (SNRF) did not make the federal Endangered Species Act list due in part to research conducted in Oregon showing a significant extension of the species’ range. This may be due to the foxes' monogamous mating system and highly specific mate selection. SNRF is one of three of North America's ten red fox subspecies that reside in high elevation areas. When: September 11, 2018 @ 7:00 pm – 8:15 pm Where: McMenamins Old St. Francis School, 59800 South Highway 97, Bend, OR 97702, USA Scientists recently discovered the Sierra Nevada red fox, a subspecies once thought to be restricted to high-elevation areas, living at lower elevations than expected. “Radio-collared foxes could give us information on habitat use, denning activities, foraging behavior, seasonal elevational changes and sources of mortality.” Hiller said six SNRF have been captured in past and present studies in California. The gestation period of the fox is about 51 to 53 days. Our region is home to three kinds of montane fox, the Sierra Nevada red fox (Vulpes vulpes necator) in the Oregon Cascades and Sierras, the Cascade red fox (V.v.

Conduct genetic studies. At home in elevations above 6,000 feet, Sierra Nevada red foxes live amongst red fir, lodgepole pines, and alpine fell-fields. Capture activities continued for the month of May and were scheduled to resume again later in the fall when success rates are higher than other seasons. The West Cascades ecoregion extends from east of the Cascade Mountains summit to the foothills of the Willamette, Umpqua, and Rogue Valleys, and spans the entire length of the state of Oregon. Scientists recently discovered the Sierra Nevada red fox, a subspecies once thought to be restricted to high-elevation areas, living at lower elevations than expected. Only one native subspecies of mountain-dwelling fox roams Oregon's Cascades, and until recently it was assumed to be the Cascades red fox — the same montane subspecies found across the Columbia River in Washington. Active mostly at night, Sierra Nevada red foxes spend winters in dens in earthen cavities in mature forest, and summer in high meadows, fell fields, talus slopes and shrub lands. 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. Additional research findings from this phase of the project will be coming out in the near future. cascadensis) found in the Cascades north of the Columbia River, and the Rocky Mountain red fox (V.v. Fish and Wildlife Service’s decision not to list the species in Oregon. [2][4] The fox is a data gap species in Oregon[5] and designated an Oregon sensitive species by the U.S. Forest Service. Strategy Species include those with small, declining, or unknown population levels that could be at risk and may be in need of conservation. 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. The single female found is in its adult stage and is the first of its kind to ever be caught in the state. The U.S. Less then two months later the female gives birth to a litter of 4-5 kits. Jefferson, Mt. Evaluate competition from coyotes. [1] No other populations are known. Sierra Nevada fox family is recorded on Central Oregon camera-trap video.

The Sierra Nevada red fox (SNRF; Vulpes vulpes necator) historically occurred throughout the Pacific Crest Ranges of California and Oregon. The Sierra Nevada red fox Vulpes vulpes necator is a native subspecies associated with subalpine regions in the Sierra Nevada and Cascade mountain ranges of California and Oregon. Fish and Wildlife Service’s decision not to list the species in Oregon, SNRF is an Oregon Conservation Strategy Species. [27] A similar boundary may exist between Sierra Nevada red foxes and both the Sacramento Valley red fox and the introduced lowland foxes.

Other project cooperators and funders include Wildlife Ecology Institute, U.S. Forest Service, UC Davis, The High Desert Museum, Cascades Carnivore Project, Oregon Wildlife Foundation, and Oregon Zoo Foundation. [9][10] Joseph Grinnell identified separated montane fox populations in the Oregon Cascades, Mount Shasta, Lassen Peak, and Sierra Nevada in 1937. They have similar characteristics to other red fox subspecies in the West, including the Cascade and Rocky Mountain red fox. All information on this website is considered. Red fox management policies and regulations in California (including Sierra Nevada red fox, Sacramento Valley red fox, and lowland non-native red fox populations) Pete Figura. [1], 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. Less then two months later the female gives birth to a litter of 4-5 kits. The Sierra Nevada red fox is designated as a sensitive species and classified as a data gap species in Oregon. It is largely dominated by conifer forests, moving into alpine parklands and dwarf shrubs at higher elevations. Describe population dynamics. SNRF generally are smaller than other red foxes and average about eight pounds. It is generally smaller than other red foxes in North America and has an elongated snout, large ears, slender legs and body, and a bushy tail with a white tip.

Project leaders Hiller and ODFW wildlife technician Jack Vaughn hope to capture and radio-collar 10 SNRF by the end of June 2018. Photo courtesy of Laurie Turner (8/14/2013) Sierra Nevada red fox (Mt. The Rogue watershed has the largest population of any coastal watershed in Oregon (Jackson County, Josephine County, and a portion of Curry County). This species is experiencing greater conservation threats at the southern edge of its range, so efforts to provide habitat in Oregon are especially beneficial. All known populations of the subspecies are found on public lands. Support data collection efforts to distinguish between eastern red fox and Sierra Nevada red fox. [7] All three phases occur in the Oregon Cascade and Sonora Pass populations, but only red phase individuals have been found in the Lassen population. A second SNRF, a male, was captured about a week later, and a juvenile born that year was captured and collared in August 2017. Fish and Wildlife Service.
