More than 4,500 square miles of ocean will soon be protected by the federal government off the Central California coast. The Biden administration is creating a new national marine sanctuary, which will be the third largest in the U.S.

The sanctuary is also the first to be led by Indigenous people. It was nominated by members of the Northern Chumash Tribe, who drove the effort for more than decade to protect the rugged coastline that is their historical homeland.

Going forward, the new Chumash Heritage National Marine Sanctuary will be managed in partnership with tribes and Indigenous groups in the area, who will advise the federal government. It marks a growing movement under the Biden administration to give tribes a say over the lands and waters that were taken from them.
