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.

There’s nothing quite like the first signs of life in the nursery; our chestnut seedlings are officially emerging! After weeks of careful stratification, planting, and patience, we’re starting to see those first tender shoots break through the soil. Early seedling emergence is a critical stage, showing us that germination was successful and that strong root systems are beginning to establish beneath the surface. These seedlings will be used for our Recurrent Genomic Selection program, including future seed orchards, progeny tests, small stem assays, phytophthora root rot screening. Here’s to healthy growth, strong roots, and a thriving season ahead! #AmericanChestnut #RestorationInProgress #ChestnutResearch #ForestRestoration #MeadowviewResearchFarms #ConservationScience ...

Meadowview for the Win!🏆

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.
