Studying and saving Yosemite's diverse wildlife, including many threatened species.

The park’s protected landscape supports an astounding array of wildlife, including more than 400 kinds of mammals, birds, amphibians, fish and reptiles, and provides a haven for threatened and endangered species.

With your support, wildlife experts help ensure that Yosemite’s diverse animals, from tiny butterflies to 250-pound black bears, can thrive in their natural habitats. Donor-funded projects have helped park wildlife teams bring endangered bighorn sheep back to the Cathedral Range after a century-long absence; restore populations of California red-legged frogs and western pond turtles; record the first sighting of a rare red fox inside the park in 99 years; dramatically reduce bear-related incidents through visitor education, effective food-storage solutions and bear-monitoring technology; and much more.
