Volunteers Power Our Mission

Many hands make light work! TACF volunteers are interesting, inspired folks you get to know as you work, learn, and grow trees together!  If you crave connection and want to create positive change, Maine TACF is a great place to give and to get both.

We believe that we can recreate the forest community and revitalize our human community at the same time. We’re doing it day by day. Won’t you join us?

With your help we can accomplish these tasks and more this year:

Chestnut Restoration — Join or start a Chestnut Restoration Team near you. Plant, tend and share chestnut trees and their story with others. Chestnuts-Across-Maine partners with local land trusts, parks, schools and towns to connect people and chestnuts. 

Potting seeds — In February we gather at a member’s greenhouse to pot up the nuts that will become the seedlings of 2025.

Inoculating — In June we will inject live blight fungus into the bark of about 3000 trees in our seed orchards in Searsport, Phippsburg, Stetson, Hartland, and Winthrop, to see if the trees show any sign of blight resistance.

Evaluating — Trees inoculated in June of 2024 will be evaluated by TACF scientists to see how well they fared against the fungus.

Roguing — From May through October any trees that succumbed to the blight will be cut down and removed from the seed orchards, leaving more room for the other trees.

Pollinating — In July or August, volunteers will transfer pollen collected from our more promising trees to the blooming flowers of other high performing chestnuts.

Harvesting — In the fall we’ll gather nuts from pure American chestnuts and any hand pollinated “best by best” crosses. The narrow harvest window is usually September 25 through October 10.

Husking— A couple weeks after harvest, it’s all hands on husks to open the spiny burs (with tough gloves) to reveal 2-3 delicious, sweet nuts tucked inside. Hot cider, roasting chestnuts and lively conversation remind us why volunteering is so rewarding.

Time is our most precious resource to give. At TACF we treat your time like a valuable gift to the future. Opportunities abound for volunteers, even those who don’t love field work. Take this easy first step: Sign up to volunteer. Our volunteer coordinator will contact you to help you find a good fit for your skills and interests.

Grab your camera and hit the trails—the American Chestnut Photo Contest is back! We’re looking for striking, creative, and unique images of American chestnut trees and hybrids.

The first-place winner will have their photo featured on the cover of a future issue of Chestnut magazine and receive a one-year TACF membership, along with a T-shirt and hat. Open until December 31, 2025

Fall work is in full swing at Meadowview! 🌰 Lucinda and Dan are planting a Castanea seguinii from Dr. Hill Craddock (University of Tennessee at Chattanooga) in our Castanetum, home to chestnut relatives from around the world. Nearby, we’re selecting top performers from a 2018 progeny test—thinning the stand to release the best 10% for future breeding success. #AmericanChestnut #RestorationInProgress #ChestnutResearch #ForestRestoration #MeadowviewResearchFarms #Castanetum #ScienceInTheField ...

Join us on Friday, November 21, 2025, from 11:30AM – 1:00PM (ET), for the next LIVE Chestnut Chat webinar.

Our special guest, Dr. Jessica Rutkoski, is a small grains breeder with a talent for explaining the fundamentals of breeding and quantitative genetics. In her talk, she will describe how modern tools such as genomic selection and high-throughput phenotyping can speed up improvement for multiple traits—and how these technologies can be effectively applied to TACF’s American chestnut breeding program. Jessica is a quantitative geneticist and leads the winter wheat breeding program at the University of Illinois at Urbana-Champaign.

🍂 As autumn arrives, chestnut trees at TACF’s Meadowview Research Farms enter dormancy, leaves turning gold and brown before falling. This cozy pause is nature’s renewal, while staff use the time to plan, prepare, and continually refine methods across the field, nursery, and lab. Dormancy sets the stage for a strong spring and a year of progress in chestnut science. 🌳
