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.

Grafting is one of the tools we use to conserve large, surviving American chestnut germplasm and ensure it isn’t lost. By grafting scion from important trees onto compatible rootstock, we can preserve valuable genetics and share this germplasm across regions. This work allows exceptional trees to live on in multiple locations, supporting research, restoration, and collaboration while safeguarding the diversity of the American chestnut for the future.

Our Director of Science, Jared Westbrook, was interviewed by Ira Flatow, founder and host of Science Friday, for their podcast. The episode is now available: www.sciencefriday.com/segments/restoring-american-chestnut-tree/

On Science Friday, Jared discusses the multiple approaches taken to improve blight resistance in American chestnut trees, TACF’s recurrent genomic selection program as our main engine for restoration, and what successful restoration looks like.

Black History Month provides an important opportunity to honor the past while also recognizing how Black knowledge, leadership, and community continue to shape the present. From histories rooted in land and survival to modern platforms and outdoor spaces where connection and representation matter.

Today we’re highlighting Hattie Carthan, who fought against the impacts of redlining and disinvestment by mobilizing her Bed‑Stuy community to restore its trees and protect a landmark magnolia. Her legacy shows that restoration starts with us, an idea at the heart of our work to revive the American chestnut.

So trees DO grow in Brooklyn again?!

Our air pruning bed was constructed in early 2025 and has since been growing hybrid chestnuts that play an important role in our grafting work. Air pruning beds allow us to grow strong, well-branched root systems and make it easy to access high-quality rootstock for grafting. MRF staff are currently grafting using the root stock from trees that were grown in this air pruning bed, so stay tuned to learn more about it next week!

Our research just dropped in Science, and the media wrapped it in love.

Here’s your Science Release Wrapped: the most notable mentions, the biggest themes, and the breakout moments that made RGS the star of the week.

Thanks for all the love.
