1904
First Audubon Chapter founded in California | Founded in 1904 as “California Audubon” after renowned field biologist Joseph Grinnell’s first Pasadena bird list was published, the organization became the first local Audubon chapter in California. In 1909, members held their first outdoor meeting in the Arroyo Seco, identifying 22 bird species, and the group adopted the name Pasadena Audubon Society to distinguish itself from other Audubon chapters.
1939
Building Audubon’s California Presence | In 1939, the Los Angeles Audubon Society created and began operating the San Gabriel River Wildlife Sanctuary in Whittier Narrows. By 1942, the National Audubon Society had established a small nature center there known as the Audubon Center of Southern California. Established as part of a major membership effort that also helped launch several new California chapters, the Audubon Center of Southern California later became the Whittier Narrows Nature Center, now operated by the County of Los Angeles, and served as a precursor to what is now the Audubon Center at Debs Park.
1957
Richardson Bay Audubon Center & Sanctuary | The center & sanctuary was established in 1957, securing a vital Bay habitat that would become a lasting place for bird conservation, stewardship, and community connection.
1968
Audubon’s Western Regional Office (based in Sacramento) | The office was established in 1968, laying the foundation for a stronger and more sustained presence in California policy and conservation work.
1970
California Environmental Quality Act (CEQA) | The act was established in 1970 as a statewide process for reviewing environmental impacts, considering alternatives, and reducing avoidable harm before projects move forward. For Audubon California, CEQA has long been an important law for protecting birds, wildlife, and communities from harmful development, and one that Audubon California, alongside California chapters, continues to work to uphold.
California Endangered Species Act (CESA) | The protections were originally enacted in 1970 and updated in 1984, creating a strong state framework for protecting species at risk of extinction. CESA is an essential safeguard for birds and wildlife, helping protect species such as the Tricolored Blackbird, California Least Tern, and Least Bell’s Vireo.
1973
1975
Bobelaine Sanctuary | Established in 1975 through a donation from Bob and Elaine Crandall, the sanctuary helps protect rare Central Valley riparian habitat along the Feather River. Today, it is considered a “State Ecological Reserve” and an Important Bird Area.
1976
The California Coastal Act | The act created one of California’s most important conservation frameworks, to protect public access and helping safeguard coastal habitats and wildlife. Support for that vision reaches back even earlier: local coastal chapters, including Santa Barbara Audubon, were encouraging members to engage in 1972 around Proposition 20, the ballot initiative that helped lay the groundwork for the California Coastal Act. Audubon California has long supported and defended the Coastal Act’s promise, and in 2026, we are supporting the legislative resolution honoring its 50th anniversary.
The Williams Sisters Ranch Sanctuary | Through the sisters’ donation, the sanctuary was established in 1976. The addition of this sanctuary protected working landscape to Audubon’s California sanctuary system. The 1,200-acre historic cattle ranch is located along Skyline Drive in Woodside, California.
1983
Supreme Court Win for Mono Lake | Mono Lake’s ecosystem, essential to bird life, nearly collapsed in the 1980s. The City of Los Angeles began diverting four of Mono Lake’s five main creeks in 1941, and over the course of 40 years, the lake dropped 45 feet, increasing in salinity to the point where its brine shrimp almost couldn’t survive. The National Audubon Society, along with the Mono Lake Committee, brought suit, and in 1983 the California Supreme Court ruled it was the state’s duty to safeguard the environment for all, even if that meant a shuffling of once-inviolable water rights. This was an unprecedented decision, a landmark for the environmental movement, and Mono’s level was stabilized.
1987
A Last Resort for California Condors | As California Condors hovered on the brink, Audubon advocated for the controversial decision to bring the last wild birds into captivity—a critical step toward recovery and reintroduction.
California Condor #20 is the oldest living condor in the wild and one of the last surviving birds born in the wild before the remaining population was brought into captivity to begin the breeding program. Captured in 1985, #20 later sired more than 30 chicks that were released back into the wild, and he was released in 2015.
1989
Wattis Sanctuary | Located in Colusa, California (Sacramento Valley), the sanctuary was established in 1989, expanding Audubon’s network of protected lands in California.
1992
Marbled Murrelet Protections | The Audubon network played an important role in advancing protections for the Marbled Murrelet over several decades.
1993
Western Snowy Plover Support Along the Pacific Coast | Audubon helped ensure crucial safeguards for the Western Snowy Plover.
1996
Audubon California was established, creating a statewide organization dedicated to bird conservation, habitat protection, and environmental policy across California.
1997
Kern River Preserve | The preserve was established in 1997, protecting a vital riparian landscape in the southern San Joaquin Valley for migratory birds and resident wildlife.
2003
2006
Bay Area HQ | Audubon California established its Bay Area Office in 2006, expanding regional capacity for restoration, policy, and partnership work in the San Francisco Bay.
2007
Bobcat Ranch | The ranch was established in 2007, protecting a working landscape that supports birds, biodiversity, and conservation on private lands.
2008
Audubon California Helps Launch a Collaborative Path Forward at Owens Lake | The lake is located at the base of California’s Inyo Mountains, covering nearly 100 square miles.
“For many years, Mike Prather (Eastern Sierra Bird Alliance) was a lone voice for Owens Lake. By the time we met in 2006, he showed up with huge three-ring binders full of articles, photos, data, and testimony from years of public advocacy. He really accosted me with those binders—and I mean that affectionately. It was clear how much urgency, persistence, and personal commitment he had brought to protecting Owens Lake. In response, Audubon California immediately committed staff time and resources to Owens Lake, and Mike’s determination was a big part of why that work moved forward.”

The Tejon Ranch Conservation and Land Use Agreement | Audubon California helped secure a landmark conservation agreement at Tejon Ranch, and joined conservation partners in the Tejon Ranch Conservation Agreement, helping protect up to 240,000 acres of grasslands, oak woodlands, streams, and desert habitats. These stunning landscapes support birds such as the Bald Eagle, Golden Eagle, Western Burrowing Owl, Swainson’s Hawk, state-threatened Tricolored Blackbird, and Loggerhead Shrike, and are also home to the federally endangered San Joaquin kit fox.
The conservation easements were purchased by the independent Tejon Ranch Conservancy, which was created as part of the 2008 agreement, through a grant provided by the State Wildlife Conservation Board. (Audubon California plays a special role on behalf of the conservation groups that signed the 2008 agreement by holding third-party enforcement rights should the easements ever be violated).
2012
North Coast Marine Protected Areas | Audubon California and Mendocino Coast Audubon helped lead efforts to establish the North Coast Marine Protected Areas, a network of more than 100 protected ocean areas and special closure zones approved from the Oregon border to Point Arena. The protections, which remain in place today, helped safeguard seabirds, shorebirds, and important coastal bird habitat along California’s North Coast.
Aramburu Island Shoreline Protection | After the 2007 Cosco Busan oil spill, Audubon California identified Aramburu Island in Richardson Bay as critical refuge habitat for birds escaping contaminated waters. That urgency helped spark the Aramburu Island shoreline protection and ecological enhancement project, completed in 2012 to stabilize the island’s eroding eastern shoreline, improve aquatic, wetland, and upland habitat, and strengthen resilience to sea level rise. Since then, thousands of native plants have been installed and volunteers have contributed thousands of hours to ongoing restoration and stewardship.
San Joaquin River Restoration | Audubon California launched the “I’m for the River” campaign with coalition partners to build public support for San Joaquin River Restoration Program (approved by Congress in 2009), working with San Joaquin Audubon, Stanislaus Audubon, Fresno Audubon, and Yosemite Audubon to encourage grassroots advocacy across the Valley. Through local outreach and coalition work, Audubon helped rally support for restoring habitat, clean water, and public access along one of California’s most altered river systems.
2014
The Sustainable Groundwater Management Act (SGMA) | Audubon supported SGMA, a landmark law that created a new framework for balancing groundwater use with the long-term health of farms, wetlands, and wildlife habitat; requiring sustainable groundwater management by 2040. Local Groundwater Sustainability Agencies (GSAs) are now required to develop Groundwater Sustainability Plans (GPSs) to chart a course to 20-year sustainability in overdrafted basins.
BirdReturns Pilot | The initial BirdReturns program pilot launched in 2014 during severe drought, providing habitat where birds need it most. BirdReturns is a collaborative program of the Migratory Bird Conservation Partnership, which is comprised of Audubon California, The Nature Conservancy (TNC), and Point Blue Conservation Science, working together to create habitat for resident and migratory birds across the Pacific Flyway. The initial pilot for the collaborative BirdReturns project was managed by TNC in 2014.
Richardson Bay Youth Leaders | Initially launched in 2014, the program helps young people build environmental knowledge, leadership skills, and a deeper connection to local conservation.
