California gets final approval for nation’s third-largest marine sanctuary
Chumash Heritage National Marine Sanctuary now protects 4,543 square miles of California coastline, making it the country’s third-largest marine sanctuary and the first anywhere in the U.S. shaped from the start by Indigenous tribes. The waters off San Luis Obispo and Santa Barbara counties are so biologically rich that one Chumash leader compares them to the Galápagos, and they’re now off-limits to oil and gas exploration. The designation also safeguards ancient village sites resting on seafloor that was dry land thousands of years ago. After a decade of tribal-led advocacy, this sanctuary offers a new model for ocean conservation — one where the people with the longest relationship to a place help decide its future.
