Tribal communities in Northern California’s mountainous interior are celebrating the recent designation of Sáttítla Highlands National Monument after decades of advocacy work to increase land protections in the area.

U.S. President Joe Biden on Tuesday will create two new national monuments in California, solidifying his legacy as the U.S. leader who has conserved more lands and waters than any of his predecessors.

The new designation near Joshua Tree National Park protects wildlife and preserves Indigenous spiritual and cultural values tied to the land.
