Pennsylvania Chapter of The American Chestnut Foundation
Historical Summary and Milestones

The Pennsylvania Chapter of the American Chestnut Foundation was founded in 1994 with incredible help and enthusiasm from its founding members. What has driven the Chapter from inception to its present state is the continued and almost unbound enthusiasm and work ethic of its volunteer members. Without the

tireless efforts of Ann and Bob Leffel, the Chapter‘s founders, the following milestone’s would not have been reached. When Dave Armstrong joined the effort, the Chapter reached new levels of outreach, fundraising, and success. Many others have contributed amazing amounts of energy, funding, land, and support. And they are those to whom this Chapter owes a great debt of gratitude. Spring 1988 - First TACF Backcross planting in Pennsylvania at Reineman Wildlife Sanctuary.

Eight down… a few hundred to go! (JK! We have bagged far more than eight.) But, after suffering a late freeze this spring, our central PA chestnut trees are just a bit behind their southern counterparts in the growing season. Which means while theirs are wrapped, our bagging days are still underway! Noah was kind enough to take a moment in the canopy to share about his bagging process with us. Pretty cool!

Now imagine all the bags on all the trees across the native eastern range… Think about all of the dedicated people, staff and volunteers alike, responsible for the thousands of controlled pollinations happening this summer. American chestnut restoration is an incredible group effort of conservationists spread far and wide. So many caring people braving the heights for the cause. Pretty amazing, don’t you think?

How do you know if your soil is good for ? Lake gives us some good tips for assessing through observation.

Chestnuts like well-draining soil, like a nice sandy loam. (Have you tried the “ribbon test”?)

They prefer slightly acidic soil with a pH between 4.5 and 6.5. (Look for nearby indicator species, like wild blueberries, wild strawberries, and teaberry-AKA wintergreen).

Of course, you can get technical and send your soil out for testing, but these methods can give you a good idea of what to expect.

It may look like a hungry little caterpillar has been dining in our greenhouse, but nope!

Noah’s been busy genotyping - taking a DNA sample of top offspring from previous controlled crosses. The samples will be evaluated using the Recurrent Genomic Selection model to select the most disease-resistant offspring based on their DNA profiles.

The top 10% of offspring will be chosen for the next round of parent selections. The rest will be field tested for long-term disease response to add more data to the model.

Come out to see us at the Central PA Native Plant Festival on Saturday! There will be music, food, educational presentations, and yep- you guessed it- plants! 🌱 🪴 It will be a lovely day to celebrate the native landscape of Happy Valley! Added perk for us is that we’ll likely run into Jean, our wonderful previous chapter administrator who is heavily involved with the Central PA Native Plant Society. Will we see you too? 🤞

🌧️ Talk about dedication! Saturday’s planting event, in which partnered up with , was a wet one! But it was a rain or shine day, and while it sure did rain, these volunteers chose to show up and shine all the same! Fun fact: PA soil rocks! No wait- make that- PA soil is rocky! It’s the PA volunteers who rock! 🤘 So do the folks at who worked with TACF Regional Science Coordinator, Lake Graboski, to organize this particularly productive planting party!
