California Big Trees

Official Registry of California Big Trees

Smoke Tree
Smoke Tree

The California Register of Big Trees is a program of the California Department of Forestry and Fire Protection (CDF) and the Northern and Southern California Societies of American Foresters (NorCal SAF). It maintains records for the largest specimen of each native and naturalized tree species growing in California. The register seeks to recognize and sustain these living landmarks. Not all champions are literal giants like the General Sherman Giant Sequoia. The National Champion Smoke Tree, for example, is a mere 17 feet tall, with a crown spread of 12 feet and circumference of 48 inches.

California has 334 Big Tree listings, 132 National Champions and 39 Co-Champions.
