New effort aims to replant functionally extinct American Chestnut trees across New York City

Researchers are working to make the American Chestnut more resistant to the fungus that wiped them out. American Chestnut trees nearly wiped out by fungus A fragile sapling now taking root in Green-Wood Cemetery's Chestnut Path is part of an ambitious new effort to bring back a tree that once dominated northeastern forests. The American Chestnut was once considered one of the largest and fastest-growing species in the region, but a deadly fungal disease nearly wiped it out. Now, a partnership between the New York Restoration Project and the American Chestnut Foundation is working to change that. "Scientists estimate that we lost around 3 billion trees within a really short window of time," said Jason Smith of the New York Restoration Project. "It was the first real disaster caused by an invasive disease in our forests after colonization." The project aims to plant 1,000 American Chestnut trees in New York City over the course of several years. The species is considered functionally extinct due to a blight caused by a fungus identified at the Bronx Zoo in 1904. Over the next few decades, the trees were nearly wiped out. "In the wild, they don't grow to maturity anymore," Smith said. "They rarely flower or fruit. So the role they played in our forest is gone." Researchers hope to make trees more resistant to blight A small group of chestnuts is now growing at the cemetery, though several have already succumbed to the disease. Researchers are closely observing the survivors to better understand resistance patterns. The few trees that continue to thrive are being propagated for future planting across the five boroughs. "Our chestnuts are really productive," said Sara Evans, Director of Living Collections and Curator at Green-Wood Cemetery. "They flower and produce a ton of nuts every single year." Each tree in the program is tagged with a unique number so scientists can track its development over time. The long-term goal is to isolate the genetic traits that provide resistance to the blight. So far, partners say more than 100 trees have been planted by volunteers and local institutions participating in the multi-year restoration effort. Organizers say the work is both ecological and cultural. "New Yorkers used to eat a ton of chestnuts, like just from food carts on the streets. Like, that's how abundant the chestnuts were way back in the day," Evans said. "Environmentally really important ... considered one of the keystone species in our northeastern forests." The return of this lost giant begins with one baby seedling, quietly taking root in Brooklyn's historic Chestnut Grove. Registration for planting chestnut trees this spring has closed.

Lecture series goes out on a limb discussing reviving the American Chestnut tree
ELKINS, (WBOY) — The Kump Education Center in Elkins welcomed community members Wednesday evening for a lecture titled 'Returning the American Chestnut to Our Forests.' The event featured guest speaker Mark Double, a representative from the West Virginia Chapter of the American Chestnut Foundation, who dug deep providing insight to those in attendance about the foundation's ongoing efforts to restore the American chestnut tree to its native habitat in the forests of the Northeast. Double also discussed the challenges posed by the chestnut blight that has nearly wiped out the American chestnut tree species. 'So, we're using a back cross breeding technique where you take American chestnut and Chinese chestnut and you cross them. You'll produce nuts out of those and those initial nuts will be 50% American and 50% Chinese. Your plant those nuts, you grow them up into trees that are 5 to 6 years, and they begin to flower, and you take flowers from those trees, and you back across to pure American,' Double said. The lecture was free of charge and open to the public, offering attendees an opportunity to learn more about the importance of the American chestnut tree and the initiatives being undertaken to ensure its resurgence in the region. One of West Virginia's first flowering trees in spring is actually invasive 'This is an extremely important tree in terms of mass production because unlike oaks, which would produce acorns every other year, chestnut produced chestnuts every year because it doesn't flower until mid to late June. So, by that time frost is gone and you have a great crop of chestnuts every single year,' Double added. ' Also, the Kump Education Center will host its next free tree talk on Wednesday, April 23, at 7 p.m. titled 'Stress, Strain, and Trees: An Introduction to Tree Mechanics and Risk Assessment.' That lecture will feature guest speaker Ken Beezley, Instructor of Sustainable Resource Management at Davis and Elkins College. Copyright 2025 Nexstar Media, Inc. All rights reserved.
