Located in the central Sierra Nevada,Yosemite is particularly noted for its textbook-perfect glacial features—granite domes, moraines, sheer rock walls, and hanging valleys—as well as its stunning waterfalls. Nearly 95 percent of the park is designated Wilderness. The park's 747,956 acres or 1,169 square miles are home to hundreds of wildlife species and thousands of Yosemite plants. Designated a World Heritage Site in 1984, Yosemite is known for its granite cliffs, waterfalls, clear streams, giant sequoia groves and biological diversity. Two Wild & Scenic Rivers, the Tuolumne and Merced rivers, begin in the park and flow west to the Central Valley. More information about natural resources in Yosemite is available through the park's Nature and Science web page.

At Yosemite National Park, the Sierra Nevada Network (SIEN) monitors birds, high-elevation forests, lakes, river hydrology, and wetlands, and does climate reporting using existing meteorological stations where data are collected primarily by park staff. SIEN also funded numerous biological inventories of vascular plants and vertebrate animals in Yosemite between 2001–2005, and more information is available under the Inventory Reports tab near the top of this page.

Bird Monitoring Project Takes Flight

Bird monitoring was initiated in Yosemite, Sequoia, and Kings Canyon national parks and Devils Postpile National Monument in 2011 as a collaborative project between The Institute for Bird Populations and the Sierra Nevada Network. During the first season, extremely late-lingering snow and high streamflows prevented or delayed safe access to many middle and high-elevation monitoring sites. Despite access issues, field crews were able to sample 51 out of 60 transects in Sequoia & Kings Canyon and Yosemite. They conducted 744 point counts, documenting 6,507 individual birds and 96 species. An additional 25 species were recorded as incidental detections.

Two species of particular conservation interest—bald eagle (formerly a federally endangered species) and black-backed woodpecker (currently a candidate species for listing as threatened or endangered in California)—were detected and documented in Yosemite. More specific information is available in the 2011 annual report (Holmgren et al. 2012).

Park Species Lists

Select a Species Category (optional):

What's the difference?

A Checklist contains only those species that are designated as "present" or "probably present" in the park.

The Full List with Details includes all the Checklist species plus species that are unconfirmed, historically detected, or incorrectly reported in the park. The Full List also contains species that are "in review" because their status in the park hasn't been fully determined. Additional details about the status of each species is included in the Full List.

The Checklist will almost always contain fewer species than the Full List.
