American Chestnut reintroduction project takes off at Patoka Lake

A project vision has come to fruition at the U.S. Army Corps of Engineers’ Patoka Lake in Dubois, Indiana: The Patoka Lake American Chestnut Regeneration Study Orchard. This project revives history and embodies the spirit of community collaboration and environmental stewardship.

Together, a multi-agency team of volunteers has planted nearly 300 American Chestnut trees at Patoka Lake with the collective aim of allowing all to witness and study the historic return of this native tree species.

The project will reintroduce the first stand of American Chestnuts to USACE properties in Indiana. The staff at Patoka Lake envisioned a sustainable future for a plot of land near the project office by partnering with organizations like The American Chestnut Foundation, the Boy Scouts of America, Northeast Dubois High School, the Dubois Ruritan Club and Dubois Rural Electric Cooperative.

“The community has been really excited about working on this project,” said U.S. Army Corps of Engineers Louisville District Park Ranger Jim Merkley. “It is a great feeling to help bring a tree that is ‘functionally extinct’ back to its native range for public viewing and future study.”

According to the American Chestnut Foundation, the American Chestnut was a dominant species throughout the Eastern United States and played a vital role in ecosystems and human livelihoods. However, the devastating effects of the chestnut blight brought it to the brink of extinction. Now, through dedicated research and conservation efforts, Patoka Lake is proud to be part of the historic endeavor to restore this iconic tree.

Extensive preparation was necessary to determine whether the project would be viable indefinitely. Patoka Lake Manager Steven Rector and Park Ranger Jim Merkley conducted a feasibility study to ensure compatibility with soil conditions, slope, other environmental factors and potential tree availability.

The team reached out to current and future partners to gauge interest in the potential project, including participating in the Partnership Handshake webinar last fall and subsequently applying for a Handshake Award. The Patoka Lake American Chestnut Regeneration Study Orchard project was one of six selected throughout USACE to receive the Handshake Award. The award fully funded the supplies and materials needed for the project.

Protected by seven-and-a-half-foot-tall deer exclusion fences, the roughly half-acre plot is now home to nearly 300 American Chestnut trees. While expectations are tempered by the experimental nature of the project, the goal is for 50-75 percent of the trees to reach full maturity, paving the way for even more blight-resistant trees in the future.

For the team at Patoka Lake, the most rewarding aspect of the project is the opportunity to educate and inspire future generations.

“Our favorite part of the project has been educating our partners, high school agriculture students and Boy Scouts,” said Merkley. “Seeing the excitement when people realize how important their work is, not only for today, but for their children and grandchildren in the future. We also look forward to introducing and educating the public through programs, open houses, and tours for years to come.”
