Southern Indiana Volunteer Opportunity: Measurements and Genetic Sequencing

When: Sunday, May 22: 9am – 5pm

Where: Jackson-Washington State Forest
Behind 7785 IN-135
Salem, IN 47167

There are two plantings at this location: a BC3F1 breeding orchard planted in 2003 and a BC3F3 progeny test planted in 2014. Our focus for this event will be the 2003 BC3F1 orchard. In order to determine which trees of TACFs backcross breeding program are the “best of the best”, we are implementing a combination of new phenotyping (measuring trees’ outward appearance) and genotyping (genetic sequencing). By comparing the phenotypic measures to the underlying genotype, TACFs Director of Science, Jared Westbrook, can better determine which trees have the best disease-resistance across the organization’s range-wide breeding program.

We will be measuring the trees, taking metrics such as height, diameter, crown health, etc., and also collecting young leaves from all of the trees. While none of these tasks are particularly difficult, there are about 100 trees to measure and observe. We will break up into a few pairs where one person will take the measurements and another will record the information.

Volunteers are welcome to come for any amount of time they are available.

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
