In an announcement postponed by the Los Angeles wildfires, President Joe Biden on Tuesday designated two sites in California as national monuments that will honor Native American tribes while shielding picturesque mountains and deserts from mining and energy development.

The move bans oil and gas drilling, mining, and other industrial activities on vast swaths of public land in California.

Biden has federally protected 1,053,125 square miles of land and ocean in his term — an area nearly four times the size of Texas.
