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.

Join us on tomorrow, October 10, 2025, from 11:30AM – 1:00PM (EPT), for the next LIVE Chestnut Chat.

Our special guest, Dr. Trevor Walker, Assistant Professor of Forest Genetics and Co-Director of the Cooperative Tree Improvement Program at NC State University, will share insights from 70 years of breeding loblolly pine for disease resistance, growth, and stem form. He will also consider which practices are likely to succeed for American chestnut, which are not, and why.

Do you love pulling on your work gloves and cracking open freshly fallen burs to reveal the chestnuts inside? If you do, but don’t have any of your own yet, become a member and get access to our wild-type seed sale in 2026. In just a few years, your hands could be full of spiky burs and American chestnuts of your own. support.tacf.org/membership/new-regular ... See MoreSee Less

We’re proud to share this segment from the PBS show Human Footprint, featuring former TACF staff member Sara Fitzsimmons. The American chestnut sequence was selected to be adapted into a standalone YouTube video, which launched in late September and has already garnered more than half a million views. Sara’s dedication and expertise have shaped much of the progress in restoring the American chestnut. Give it a watch to learn more about this important work. ... See MoreSee Less

Great presentation!

🌰 Harvest season at TACF’s Meadowview Research Farms brings both beauty and breakthrough science. Many of the chestnut crosses we gather are generated through recurrent genomic selection—cutting-edge research driving restoration forward. Each bur holds not only the wonder of new life, but also the promise of a future where the majestic American chestnut returns to our forests. 🌳

Are there places we can purchases a Chestnut tree that is disease resistant? Thanks!

We'll be co-hosting American Chestnut Day at the NC Arboretum this Saturday! If you're local, we hope you'll join us for a fun day of speakers, activities, and even a wild-type chestnut seedling sale! ... See MoreSee Less
