SUPPORTERS

Expanding the monument is the next step in a 20-year, locally-driven effort to protect the San Gabriel Mountains. 

Over 18 million people live within a 90 mile radius of these public lands and the expansion will help increase equitable access to nature and improve public health for local residents. It will also conserve a critical drinking water source for Los Angeles County, address the climate and biodiversity crises, and honor the cultural and historical significance of the landscape. 

Hear from local and statewide supporters of this effort and then join the campaign to protect the San Gabriel Mountains forever!

“For Angelenos, the San Gabriel Mountains have been a lifelong connection to nature. For many low-income families in the Los Angeles area, this is the only access they have to green space and the educational and health benefits that come with it. And it is critical that we protect these public lands to promote environmental justice in our communities. That is why we are urging President Biden to use his authority under the Antiquities Act to fulfill the complete vision of permanently protecting the San Gabriel Mountains and all of their natural wonders.”
Senator Alex Padilla (D-CA)
"The San Gabriel Mountains are among the most pristine and beautiful public lands in the country, and they are right here next to one of the nation’s densest and most park-deprived population centers. I'm so grateful to the diverse, vibrant group of leaders of this more than 20-year movement to protect the San Gabriel Mountains, and I hope that President Biden will recognize the importance of these lands by designating the western Angeles National Forest as part of the National Monument."
Representative Judy Chu (CA-28)

Every Los Angeles County resident in every neighborhood deserves safe and accessible nature, parks, and open space. Connecting with nature benefits our mental health and overall well-being. As local leaders, we must do everything possible to ensure our communities and visitors alike have equitable access to explore nature. It’s a stabilizing space that makes a big difference in many people’s lives.”
