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.

Ways to participate:

Nominate a Big Tree Champion! This will lead you through the steps for nomination of a potential new State or County Champ. Whether or not you find an actual big tree champion, looking for the biggest trees in your neighborhood can be lots of fun and a great learning experience.

Join the NH Big Tree Team Volunteers! These volunteers work in small, county-based teams to measure trees that have been nominated and submitted to the program. The full group typically meets a few times a year for program updates, continuing education, and to share discoveries and stories.
