Treasured Landscapes, Unforgettable Experiences

The San Gabriel Mountains are important to Southern California as they contain 70 percent of the open space in Los Angeles County and provide residents with more than one-third of the county’s drinking water. The San Gabriel Mountains’ rugged geological features provide habitat to more than 160 rare, threatened, and endangered species and contain significant archeological, historical, and architectural elements.

On October 10, 2014, President Obama designated the San Gabriel Mountains National Monument from existing National Forest acreages including approximately 342,000 acres of the Angeles National Forest and 4,000 acres of the San Bernardino National Forest.

We are working with the Forest Service and Community partners to improve and enhance recreation resources, management, and interpretation. We are also working together to provide new and innovative ways to reconnect the outdoors to one of the largest urban areas in the country.

To develop priorities for managing the Monument, we are engaging community-based partners and diverse residents of the Los Angeles area in the San Gabriel Mountains Community Collaborative. Our unique role as facilitators enables us to work closely with the Angeles National Forest to bring people together to promote the health and enjoyment of the new Monument.
