Maine – About Us
The Maine chapter of The American Chestnut Foundation (TACF) was established in 1999 to help restore the American chestnut tree to our corner of America here in Maine. We live at the northernmost end of its natural range where chestnuts, like Mainers, make due with less sunshine and more cold. These suboptimal conditions made for sparser populations of chestnuts (and people) than southern climes, even before the blight.
Maine is currently home to more mature, flowering wild American chestnuts than any other state. Their success is due primarily to Maine’s geographic isolation from the denser populations of chestnut trees south of us, where the fungus spreads more readily. We have the joyful job of finding Maine’s wild trees and harvesting their nuts!
By growing chestnuts from wild trees, the Maine Chapter is preserving genes that have helped the chestnut adapt to life at the cooler edge of its range. Ultimately our gene conservation and breeding efforts are intended to produce hearty, blight-resistant populations of American chestnuts that we can use for forest restoration.
The chapter’s goals are to: 1) Protect, conserve, preserve, and propagate trees from the remaining native American chestnut populations in Maine; 2) Restore the American chestnut to a place of ecological and economic importance and self-sustainability throughout their original range in Maine, and 3) Make blight-resistant American chestnuts available to the people of Maine as soon as possible.
With your help we intend to restore this iconic species to Maine’s landscape, its wildlife, and its people.
Chestnuts Across Maine
Chestnuts Across Maine (CAM) is an exciting, new initiative of the Maine chapter of The American Chestnut Foundation (TACF). Our chapter is partnering with land trusts, state parks, schools, and town squares in Maine to establish small plantings of American chestnuts on lands open to the public. During our pilot year in 2024, ME-TACF coordinated plantings with 8 organizations! Learn more about Chestnuts Across Maine.

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)

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!
Incredibly important work…it was such a travesty for our forests!
It must've been an amazing sight to see all the trees when they were in bloom. I understand that some chestnuts were giants and comparable to sequoia. (That might have been an exaggeration...)
Just another day working to bring back the American chestnut. 🌰

Yikes. Most of those pictures look like very Chinese hybrids.
I have a hybrid chestnut sapling that did good for a few years after planting. This year the leaves turned yellow, then brown, then completely fell off. Any ideas what could cause this? The tree appears to be alive still. Thanks.
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)
Today was the last day of controlled pollinations in the southern region. Many thanks to the NC/SC Chapter members who came out to help!

Thank you for your hard work!
I'm in south Arkansas. We had miniature Chestnut call chink a pin which got wiped out in the 50s. I have found two this spring 2025. They are small.
Hello, is this a chestnut tree?
