Sierra Nevada red fox / National Park Service photo

It’s been one hundred years since a sighting of the Sierra Nevada red fox has been confirmed in Yosemite National Park. Also known as the High Sierra fox, it is a subspecies (vulpes vulpes necator) of the red fox (vulpes vulpes) and was captured on camera in Yosemite in mid-December, 2014. The California Fish and Game Commission declared this exceedingly rare subspecies threatened in 1980, and it could receive federal protection under the Endangered Species Act this year.

The Sierra Nevada red fox is slightly smaller and darker than the more common red fox, which is non-native to California. It’s range is limited to alpine and subalpine meadows above 4,500 feet.
