They found that California has the most imperiled biodiversity of any state in the contiguous United States. California is designated a Global Biodiversity Hotspot, a distinction for only 36 bioregions across the planet. We have the highest number of species and the highest number of rare, imperiled, and endemic species. More than 30% of California’s species are threatened with extinction.

With its dramatic coastlines, ocean environments, lush forests, mountains, blooming valleys with grasslands and oak woodlands, rivers, wetlands, salt lakes, and vivid deserts, it's no surprise why California’s spectacular natural landscapes host the largest, most diverse concentration of 450 species of birds in the United States.

How to Protect 30% of California's Lands and Waters by 2030

In 2020, Governor Newsom signed a groundbreaking Executive Order to protect 30% of California’s lands and waters by 2030. This goal aims to protect biodiversity, build resilience to climate change, and ensure equitable access to nature for all Californians.

The Migratory Bird Conservation Partnership, including ̽»¨¾«Ñ¡ California, Point Blue Conservation Science, and The Nature Conservancy just released a new StoryMap to demonstrate why the Great Central Valley is key to 30x30 success.  

Important Bird Areas

In addition, we have identified 177 marine and land-based Important Bird Areas that provide more than 19 million acres of essential habitat for breeding, wintering, and migrating birds. We must protect these sites to ensure the survival of our state’s rich array of birds.
