California’s coastline is 3,427 miles long, including tidal areas so important to our state’s shorebirds. It is the most heavily populated part of the state, with approximately 68% of Californians living on the coast. It therefore should not be a surprise that California’s seas and beaches are under dramatic threat from human activity, development, and climate change. Marine food resources for many California seabirds and shorebirds are also threatened by shipping, pollution, overfishing, and a host of other factors, such as ocean acidification. California’s waters, beaches, estuaries, and other habitats are vital to many of the seabirds and shorebirds that migrate along the Flyway each year, and Audubon’s conservation efforts not only improve those habitats in California, but complement similar efforts by other Audubon organizations in Alaska, Washington, Oregon, as well as partner organizations in Mexico and points further south.
