Yosemite wildlife biologists are using motion-activated cameras and genetic samples to study the rare Sierra Nevada red fox. Last winter, scientists captured an image of the fox inside the park's northern border; the species had not been seen in Yosemite for nearly a century.

Our project coordinator spent three days in Yosemite's northern wilderness with wildlife biologists who are working to learn about — and protect — one of North America's rarest mammals: the Sierra Nevada red fox. 

Wildlife biologists Sarah Stock, of Yosemite, and Dr. Alexandra Few, of California Department of Fish and Wildlife, scan the mountaintops for signs of Sierra Nevada bighorn sheep.

Sierra Nevada bighorn sheep, the majestic animals that John Muir called “animal mountaineers,” were listed as federally endangered in 2000. With support from our donors, scientists are working to study and protect these strong but vulnerable creatures. This summer, our project coordinator got to join bighorn biologists on a sheep survey in Yosemite’s high country.
