Friend of Trust for Public Land, 

We have exciting news: the White House is considering expanding San Gabriel Mountains National Monument in California! 

Now, we need to show widespread support for the expansion to ensure it’s not pushed aside. Take action now and urge President Biden to expand San Gabriel Mountains National Monument today.

Towering high above the Los Angeles Basin, San Gabriel Mountains National Monument has it all:  

The rivers of the San Gabriel Mountains are also critical for Los Angeles residents—providing about 30 percent of their drinking water. We must permanently protect these life-giving waters and the surrounding landscape. 

We can’t lose this chance to increase access to the outdoors and protect drinking water. Call on President Biden to use his authority to expand San Gabriel Mountains National Monument by 109,000 acres today! 

Adding 109,000 acres to the monument via the Antiquities Act will also increase equitable access to the outdoors for over 15 million people who live within a 90-mile radius of the expansion. Many low-income communities in the area have little access to green space in their neighborhoods, which is why it’s all the more critical that we work to protect these lands permanently.  

Please help secure these important public lands—send a letter to President Biden now.

Thank you for taking action to expand this vital landscape.
