The Angeles National Forest is a unique area nestled in the midst of an ever-changing and growing population in the Los Angeles area. The Forest is one of the few remaining open space areas in Southern California. The forest is an important part of the overall health and well-being of the area population. It provides open space, solitude from the everyday stress of modern living, a place to conduct research, a haven for wildlife, and offers a wide variety of recreation opportunities.

The Angeles National Forest was established by Executive Order in December 1892. It covers about 700,000 acres and is the backyard playground to the huge metropolitan area of Los Angeles. The Angeles manages the watersheds within its boundaries to provide valuable water to southern California and to protect surrounding communities from catastrophic floods.
