Rescuing the

American Chestnut

Our mission is to return the iconic American chestnut to its native range.

Our vision is a robust eastern forest returned to its splendor.

Harnessing the Power of Genomics

The American Chestnut Foundation is using an advanced breeding method called recurrent genomic selection (RGS) to save the American chestnut. Learn more about this exciting technique by watching this introductory video, or take a deep dive into RGS on our breeding page.

Science Strategies

Breeding, Biotechnology, and Biodiversity
United for Restoration

The American Chestnut Foundation takes a holistic approach toward chestnut restoration, utilizing a three-pronged research strategy known as 3BUR (Breeding, Biotechnology, and Biodiversity, United for Restoration). These research tracks are implemented through mutually beneficial collaborations, so we can explore all avenues to reach the common goal of saving and restoring this species as quickly as possible.

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!
