An endangered species is at risk of extinction throughout all or a significant portion of its range. A threatened species is likely to become endangered within the foreseeable future throughout all or a significant portion of its range. Both states and the federal government can list a species as threatened or endangered.

Bay Area national parks offer critical natural refuges for threatened and endangered species in an otherwise heavily developed area. Golden Gate alone is home to more of these species than any other national park, and more than Yosemite, Yellowstone, Sequoia, and Kings Canyon National Parks combined. There are also over 50 species of animals and another 50 plant species at Point Reyes that are listed by the state or federal government as threatened, rare, or endangered. There are 25 federally threatened species at Golden Gate and 12 plants found at the Presidio are designated as rare, threatened or endangered. Pinnacles is home to 26 animal species that are threatened, endangered or of special concern.

See the links below to learn more about some of these rare creatures, or the links on the right for more general information on each park’s threatened and endangered species pages.

New! Endangered Species is an art project developed by artist Todd Gilens that wraps entire San Francisco MUNI buses in beautiful images of four of the area's threatened and endangered species. Learn more at
