Research and Breeding
Here is information and some links to the types of research and breeding activities that GA-TACF supports.
Mother Trees
Chapter members spend hours searching the mountains and hillsides of Georgia for American chestnut root sprouts that can be placed into our breeding program. One of the Chapter’s first pure American chestnut trees was found on Springer Mountain by Thomas Fowler and placed in the breeding program during the Chapter’s first breeding season. Since then many other trees have been located with the “Klaus” tree near Warm Springs bringing attention world wide as the most southern tree in the piedmont area.
Without the help of volunteers identifying new trees, our breeding program would come to a halt. Each “mother tree” can only be used to cross with one type of resistant pollen from TACF’s Meadowview Research Farm to produce about 100 backcross trees. This is usually accomplished within 2 years. The more trees we find, the more diverse the gene pool will become.
Orchards
Once nuts are harvested from the resulting backcrosses a suitable orchard must be located to plant them. Berry College was the first to offer a site that would house over 200 trees. The University of Georgia’s Mountain Research and Education Center in Blairsville became our second backcross orchard. Since then we have received many offers for orchard sites that are now in the testing stage. We test for soil suitability, predator protection and overall tree care to determine the best locations for advanced backcross trees. If you are interested in hosting a backcross or demonstration orchard, please contact us at gro.fca@retpahcag.

Hello Georgia Chestnut Enthusiasts! Another volunteer opportunity... this one is pretty urgent.
We need your help with an upgrade to our chestnut orchard in Dahlonega. Hurricane Creek is a collaborative project with the University of North Georgia Biology Department and is being used to test for resistance to Phytophthora cinnamomi (black root rot disease). The orchard is progressing well, with over 100 trees in place, but we have been unsuccessful keeping the deer at bay with our electric fence. We have decided it's time to install a deer exclusion fence, similar that used at our Flint and Richards orchards. Please let us know if you can join us on for a morning shift or two to help install the fence - see dates and times. The fence goes up pretty easily and no special skills are needed. We'll provide all materials and tools, along with water and snacks.
If you can help out, please bring the following:
Hat, sunscreen, insect repellent.
Work gloves.
Water, sack lunch if desired.
Because of the heat, we'll get started each day at 8AM, and work until the heat runs us off.
Hurricane Creek is located on GA Highway 9, between Dawsonville and Dahlonega. The address is 3990 Dawsonville Hwy, Dahlonega GA, 30597. On Google Maps, maps.app.goo.gl/eTMeKLwPBEtqi2y76.
Below are the shifts for volunteers for the fence installation. Please use this link to sign up (orchard maintenance tab): theamericanchestnutfoundation.volunteerlocal.com/volunteer/?id=90470
Friday, 7/25/2025, 8AM - noon(ish), site prep work, install corner posts, layout posts, clear brush in a few areas, relocate some of the existing electric fence.
Saturday, 7/26/2025, 8AM - noon(ish), install posts, layout tarp between posts, install top polyline, install fence fabric, install bottom fabric anchors, install door.

We could really use some help with this folks! Please consider signing up for a shift. The work installing this type of fence is not that difficult, but we can definitely use some extra hands.
Hello Chestnutters!
On Thursday July 17 there will be a small stem assay workshop at the University of Tennessee - Chattanooga Fortwood Street Greenhouse. This workshop will demonstrate how TACF tests young seedlings for blight resistance. A good number of these seedlings are from our GA breeding orchards. UTC's Dr. J Hill Craddock is looking for 10 interested participants/volunteers. No experience necessary!

Last week under the leadership of Karrie Ann Fadroski and Jack Rogers, another orchard work day was held at UNG's Hurricane Creek chestnut orchard. This is the site where about 100 trees were planted via direct-seeding in March. This relatively new project is a site where trees are being evaluated for their resistance to Phytophthora root rot (PRR), a devastating root rot disease sometimes called black root rot or black ink disease. Part of this round of work included weed control and part was maintenance of the electric deer fence.
