Tree evaluation and sample collection at Jackson-Washington State Forest

On May 22, a group of volunteers assembles at Jackson-Washington State Forest. Sara Fitzsimmons, the chapter’s regional science coordinator and Steven Hoy, who manages the chestnut orchard at Penn State University in State College, Pennsylvania attended. Sara is also at Penn State and is the TACF director of restoration as well.

The purpose of their visit was to evaluate the trees that the chapter had planted in 2003 at Jackson Washington and collect samples of fresh spring leaves from the best of these trees to perform DNA sequencing on.

The chestnut trees in this planting were from the chapter’s backcross breeding program under the guidance of Bruce Wakeland and Jim McKenna. They were B3F1 hybrids, meaning that first a pure Indiana American chestnut was crossed with a pure Chinese chestnut tree, the F1 part. Then the offspring were selected and “backcrossed” 3 times with pure American chestnuts. Finally, the most American appearing and most blight tolerant trees were  selected and planted in 2003 in the Shipley Tract at JWSF. Now, almost 20 years later it is possible to rate each tree according to its degree of blight tolerance and its American chestnut appearance. leaves from best of these trees were collected and sent for DNA studies to determine the percent of American and Chinese genetics in each tree. The overall best trees will be used for further breeding of blight tolerant chestnuts.

A number of Indiana chapter volunteers attended and their help was extremely valuable. The various tasks could be assigned to small teams and this made the work go quickly. We thank them for their time and efforts.

Join us on tomorrow, October 10, 2025, from 11:30AM – 1:00PM (EPT), for the next LIVE Chestnut Chat.

Our special guest, Dr. Trevor Walker, Assistant Professor of Forest Genetics and Co-Director of the Cooperative Tree Improvement Program at NC State University, will share insights from 70 years of breeding loblolly pine for disease resistance, growth, and stem form. He will also consider which practices are likely to succeed for American chestnut, which are not, and why.

Do you love pulling on your work gloves and cracking open freshly fallen burs to reveal the chestnuts inside? If you do, but don’t have any of your own yet, become a member and get access to our wild-type seed sale in 2026. In just a few years, your hands could be full of spiky burs and American chestnuts of your own. support.tacf.org/membership/new-regular ... See MoreSee Less

We’re proud to share this segment from the PBS show Human Footprint, featuring former TACF staff member Sara Fitzsimmons. The American chestnut sequence was selected to be adapted into a standalone YouTube video, which launched in late September and has already garnered more than half a million views. Sara’s dedication and expertise have shaped much of the progress in restoring the American chestnut. Give it a watch to learn more about this important work. ... See MoreSee Less

Great presentation!

🌰 Harvest season at TACF’s Meadowview Research Farms brings both beauty and breakthrough science. Many of the chestnut crosses we gather are generated through recurrent genomic selection—cutting-edge research driving restoration forward. Each bur holds not only the wonder of new life, but also the promise of a future where the majestic American chestnut returns to our forests. 🌳

Are there places we can purchases a Chestnut tree that is disease resistant? Thanks!

We'll be co-hosting American Chestnut Day at the NC Arboretum this Saturday! If you're local, we hope you'll join us for a fun day of speakers, activities, and even a wild-type chestnut seedling sale! ... See MoreSee Less
