With over 4,210 acres of both natural chapparal-covered terrain and landscaped parkland and picnic areas, Griffith Park is one of the largest municipal parks with urban wilderness areas in the United States. Situated in the eastern Santa Monica Mountain range, the Park’s elevations range from 384 to 1,625 feet above sea level. With an arid climate, the Park’s plant communities vary from coastal sage scrub, oak, and walnut woodlands to riparian vegetation with trees in the Park’s deep canyons. The California native plants represented in Griffith Park include the California species of oak, walnut, lilac, mountain mahagony, sages, toyon, and sumac. Present, in small quantities, are the threatened species of manzanita and berberis.
