Celebrating New Hampshire's Champions


Trees have played an integral role in New Hampshire, from the days when "mast pines" were harvested for the British navy to the forests that still drive our economy today. The NH Big Tree Program measures the biggest trees in the state. Have you found a big tree? Click here to learn how to report it!

In 1950, the NH Big Tree Program began in an effort to find, record and recognize our magnificent individual trees. The list of recorded trees now includes over 1,000 county, state and national champions. NH Big Tree volunteers search the state for the largest examples of tree species and work together measuring trees in their local area nominated to the program. The group typically meets bimonthly for program updates, measuring trips and sharing discoveries and stories.
