Join us on Wednesday, July 10 at 4:00pm in the Mono Lake Committee gallery for this summer’s first Refreshments with Refreshing ‘Ologists presentation. Brian Hatfield, California Department of Fish & Wildlife researcher, will be here to discuss recent detection of the Sierra Nevada red fox in California.

The Sierra Nevada red fox (SNRF) is a subspecies of red fox native to the high-elevation regions of California and Oregon. Until recently, scientists thought the SNRF had been extirpated from California. Today we know of only two small populations of SNRF in the state, and the subspecies is a candidate for listing under the Federal Endangered Species Act.

In 2018, the California Department of Fish and Wildlife detected at least three SNRF in the Mono Creek study area northwest of Bishop. These detections mark the southernmost confirmed occurrence of SNRF in nearly 100 years, raising exciting questions about the contemporary distribution and population trajectory of SNRF in California, and prompting more intensive surveys to track this elusive carnivore at the southern edge of its range.
