In 2015, a team of wildlife experts released a herd of Sierra Nevada bighorn sheep into Yosemite’s Cathedral Range, returning an iconic species to the heart of the park's wilderness after a century-long absence.

With support from our donors, biologists continued to monitor the sheep and work toward the long-term goal of establishing a self-sustaining bighorn population. Data from GPS collars allow the team to track the bighorns’ movements remotely. On-the-ground field surveys provide additional information about the health of the herd, and about the presence of possible predators.

Your support helped scientists continue to pursue efforts to bring an endangered and beloved Sierra species back to Yosemite. To learn more about this rare mammal, watch the Yosemite Nature Notes episode on bighorn sheep:
