How to Become a Big Tree Volunteer

NH’s Big Tree Program recognizes and records the state’s biggest champions. From the “William Whipple” horse chestnut in Portsmouth to a black spruce bog in the North Country, dedicated volunteers search the state for the largest examples of individual trees species that grow in New Hampshire.

Interested in helping out? The Big Tree Team volunteers work in small groups in their local area measuring trees submitted to the program. The full group typically meets on a quarterly basis in Concord for program updates, continuing education, and to share discoveries and stories.
