New germplasm conservation orchard (GCO) in Clinton county

This orchard was established three years ago to preserve the genetic material of the Indiana American chestnuts at the Duke orchard at Purdue. The Duke trees were all cloned from old existing chestnuts from all over Indiana. Unfortunately, the Duke chestnuts have all become severely blighted, and we are in danger of loosing this valuable genetic material which we would like to use to breed blight resistant trees in the future. We were partially successful in treating the Duke trees with fungicide but we feel that the safest strategy is to reproduce the entire Duke orchard in a separate location far enough away that the seedlings could avoid blight for several years. This is why the new chestnut orchard was planted on farm land in Clinton county, Indiana.

Unfortunately, we have found blight on a few of the new trees. On October 6, 2022 chapter president Glenn Kotnik revisited this orchard and found the blight is now well controlled after a single fungicide application. Most of the trees look healthy, are growing well, and are showing their fall colors.

Our Director of Science, Jared Westbrook, was interviewed by Ira Flatow, founder and host of Science Friday, for their podcast. The episode is now available: www.sciencefriday.com/segments/restoring-american-chestnut-tree/

On Science Friday, Jared discusses the multiple approaches taken to improve blight resistance in American chestnut trees, TACF’s recurrent genomic selection program as our main engine for restoration, and what successful restoration looks like.

Black History Month provides an important opportunity to honor the past while also recognizing how Black knowledge, leadership, and community continue to shape the present. From histories rooted in land and survival to modern platforms and outdoor spaces where connection and representation matter.

Today we’re highlighting Hattie Carthan, who fought against the impacts of redlining and disinvestment by mobilizing her Bed‑Stuy community to restore its trees and protect a landmark magnolia. Her legacy shows that restoration starts with us, an idea at the heart of our work to revive the American chestnut.

So trees DO grow in Brooklyn again?!

Our air pruning bed was constructed in early 2025 and has since been growing hybrid chestnuts that play an important role in our grafting work. Air pruning beds allow us to grow strong, well-branched root systems and make it easy to access high-quality rootstock for grafting. MRF staff are currently grafting using the root stock from trees that were grown in this air pruning bed, so stay tuned to learn more about it next week!

Our research just dropped in Science, and the media wrapped it in love.

Here’s your Science Release Wrapped: the most notable mentions, the biggest themes, and the breakout moments that made RGS the star of the week.

Thanks for all the love.
