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.

Transgenic American Chestnuts are still a much better option. The product of this method will always be a hybrid and that should not be the goal.
One of the greatest ecological disasters the US has ever seen. Chestnut blight wiped out the American chestnut tree in less than 50 years.
A tree that once made up nearly 25% of the eastern forests was reduced to a functionally extinct species.
The Asian fungus Cryphonectria parasitica was accidentally introduced into the United States in the late 1800s. While a few diseased chestnuts were noted in the 1880s and 90s, it wasn't until 1904 that the pathogen was identified in New York City. From that point, the blight spread rapidly. By 1950 the entire range had been consumed.
The fungus causes cankers that spread around the trunk of the tree, girdling it and killing everything above ground. Many root systems still survive today and continue to send up shoots, but these also eventually succumb to blight. Because American chestnuts rarely survive long enough to reproduce, the species is considered functionally extinct.
The American Chestnut Foundation is working to develop blight-resistant American chestnuts that can be used to restore this iconic tree to its native range. Learn more at tacf.org/about-us (link in bio)

I think I may have found an American Chestnut tucked away in a backyard
Incredibly important work…it was such a travesty for our forests!
The trees seem to still be intact outside their range in isolated areas. Theres a few large ones here in central Michigan on a peninsula and again on the Leelenau peninsula in the nw lower peninsula. I keep seeing people chime in about adult trees here and there. Seems like there's hope!
Just another day working to bring back the American chestnut. 🌰

Yikes. Most of those pictures look like very Chinese hybrids.
I have a very old American chestnut tree that has the blight . It gets chocked off then gets new growth. It got a lot of wind this year and lost a lot of the blooms. It produces nuts still . Does anyone want to get a start of the new fruit before I move or pass way ? I’m afraid the new owners will destroy it. This was the only reason I wanted this house in the late 80’s .
Hope you are successful!!!
Especially if you're under a canopy of American chestnuts...

Unless, of course, it's fall. Then the chestnut seed pods are falling from the trees and creating a floor covered in pins and needles so sharp that it puts sweetgum to shame. You wouldn't want to be laying under the chestnut canopy then!
I live in Barboursville, WV and wanted to know if i can buy a seedling or how i go about acquiring one! Thank you!
The SHADE TREE COMMISSION in NEW PALTZ New York is interested in planting some CHESTNUT trees on Chestnut Street (Rt. 32). We would like to receive help from you if possible. New Paltz is a historic town and in the past there were MANY Chestnut trees here, Presently there is only ONE Chestnut tree which I grew from the nut of an elegant, large tree when it was sadly cut down. If there are any Chestnut trees available, or if you have any suggestion that might help us in this quest we would be greatful. Thank you for your attention., Shelly Ottens (moc.oohay@obobnyllehsih)
