Expand the boundary of CA’s San Gabriel Mountains National Monument!

I’m writing to urge you to expand the boundary of California’s San Gabriel Mountains National Monument by issuing a presidential proclamation under the Antiquities Act of 1906. The additional 109,167 acres will protect the mountains’ natural, cultural, and recreational resources, and will provide critical habitat for threatened and endangered species. The San Gabriel Mountains provide a third of Los Angeles’ drinking water and 70% of its open space for 15 million people. Expanding the boundary will increase access to nature and promote environmental justice for many underserved communities. It will help us move closer to conserving 30% of California’s land and coastal waters by 2030, in line with the Biden-Harris Administration’s America the Beautiful initiative. By issuing the proclamation, this Administration will create opportunities for healthier living, preserve biodiversity to meet the challenges of climate change, and allow future generations to become stewards of the Mountains and their natural wonders. Thank you!
