California: A Biodiversity Hotspot

California is home to more species of plants and animals than any other state in the U.S.—and also one of the highest numbers of threatened and endangered species. This interactive StoryMap offers a “flyover” of California’s birds and biodiversity, showing how coasts, deserts, rivers, and working lands are all connected.

Use this StoryMap to explore why California is recognized globally as a biodiversity hotspot, learn what makes each region unique, and discover how birds can guide smarter conservation for people and wildlife alike. Whether you’re an educator, advocate, land manager, or curious birder, this is a tool to help you see the state through birds’ eyes and imagine what a more resilient future could look like.
