Chestnut Science Update

A Year of Change

By Mark McCollough, Maine Chapter President

“Learn to expect the unexpected.” As a wildlife biologist, I learned this tenet of ecology early in my career. Nature is full of surprises from the elegant workings of the DNA molecule to the intricate cogs and wheels of a forest ecosystem. Rapid advancements in genetic science gave us both disappointment and hope for restoring the American chestnut in 2023. This issue of Maine’s Tree Urchin newsletter explains some unexpected discoveries in the world of chestnut science, how it affects chestnut restoration in Maine, and provides a peek at the year ahead.

I believe I have a few resistant chestnut trees that have produced their second crop of seeds . They are descendants of those once in living in .Valley Garden Park

Send me few, I'll plant them

What is the cure? Tx 🙏

Join us tomorrow, November 21, 2025, from 11:30AM – 1:00PM (ET), for the next LIVE Chestnut Chat webinar.

Our special guest, Dr. Jessica Rutkoski, is a small grains breeder with a talent for explaining the fundamentals of breeding and quantitative genetics. In her talk, she will describe how modern tools such as genomic selection and high-throughput phenotyping can speed up improvement for multiple traits—and how these technologies can be effectively applied to TACF’s American chestnut breeding program. Jessica is a quantitative geneticist and leads the winter wheat breeding program at the University of Illinois at Urbana-Champaign.

Will be recording be made available later for those of us who cannot attend midday?

Grab your camera and hit the trails—the American Chestnut Photo Contest is back! We’re looking for striking, creative, and unique images of American chestnut trees and hybrids.

The first-place winner will have their photo featured on the cover of a future issue of Chestnut magazine and receive a one-year TACF membership, along with a T-shirt and hat. Open until December 31, 2025
