California’s coastline stretches over 1,100 miles, harboring some of the most biodiverse marine ecosystems on the planet. From the kelp forests of the Channel Islands to the rocky shores of the North Coast, our marine protected areas (MPAs) serve as vital sanctuaries for countless species and the foundation of our ocean’s resilience.

Marine Protected Areas are underwater parks where marine life is protected from certain human activities. These ocean havens allow fish populations to recover, protect critical habitats, and help our marine ecosystems adapt to climate change. They’re essential for maintaining healthy oceans that support both wildlife and coastal communities.

California’s network of 124 MPAs covers approximately 16% of state waters, creating a system of protection from the Oregon border to the Mexican border. But as climate change, pollution, and other threats intensify, we must ensure these protections remain strong and work to expand conservation to meet our 30×30 commitment.
