Grants are available to assist members with active restoration projects within, outreach activities, and scholarly research conducted within the State of Ohio. Click here for Rules, Responsibilities, and Proposal Guidelines.
The Ohio Chapter of American Chestnut Foundation (OH-TACF) was founded largely through the efforts of Ohio scientists and as such has a strong interest in breeding, restoration ecology, and reclamation biology.
Because of the large amount of the land-base disturbed through surface mining in unglaciated Ohio, the chapter has a special devotion towards combining mineland reclamation and chestnut restoration.
Through research funded by the USDI Office of Surface Mining Reclamation and Enforcement, we have explored various ways to regenerate chestnut on previously disturbed minelands. Many post SMCRA lands in Ohio exist has monocultures of non-native species (orchard grass, autumn olive, Lespedeza, etc.) on heavily compacted soils. Natural succession to a hardwood forest community type is virtually arrested and unlikely to occur in normal time frames.
Through much trial and error, we have developed a fairly successful method of planting that results in high survival of bare root seedling plantings. A 48-inch mesh cage protects from deer browsing, a weed mat reduces competition with herbs, gravel reduces mole and vole bark stripping, fertilizer and TerraSorb enhance establishment and promote survival. This method is moderately expensive ($10/seedling) and requires 20 minutes to establish; however, survival is usually greater than 90%. We advocate this method for high quality hybrid seedlings where high survival is desired.
We have successfully used heavy equipment to loosen compacted soils and increase aeration, infiltration, and permeability. We have used a 36-inch ripping bar on a D-6 sized dozer and followed this with a 16-inch surface plow and disk on a large tractor. The above planting method is used after this type of site prep yielding excellent results.
In addition to the studies described above, the Ohio Chapter is currently beginning a program to find surviving chestnuts in Ohio forests, establish demonstration plantings, creating breeding orchards, and advancing various forms of restoration efforts utilizing American chestnut. We welcome all interested parties! Our mission is to keep the American chestnut alive in Ohio for future generations.
If you have any questions regarding current or planned research on American chestnut in Ohio, please contact Brian C. McCarthy at Ohio University.

We love to see so many people come together for American chestnut restoration.Back in August, Meadowview Research Farm staff members Lucinda Wigfield and Brian Henrich attended the NE-2333 meeting: Biological Improvement of Chestnut through Technologies that Address Management of the Species and its Pathogens and Pests. The meeting provided an opportunity to connect with fellow researchers, learn from a variety of presentations, and share in the latest developments in chestnut research and restoration.
As part of the meeting, Lucinda and Brian also joined a field trip to Johns Creek, getting an up-close look at chestnut research and restoration efforts in the field.
We’re glad that Meadowview staff were able to learn with other scientists and to be part of the ongoing work to restore this important native tree!

Is it possible to get these nuts to germinate and grow? How?
How are these different from Dunstan?
I would like to get some to plant in New Hampshire
Several chestnut enthusiasts recently had the opportunity to visit John's Creek's planting in Virginia. One of the most memorable sights was the claw marks left by black bears foraging for chestnuts as they prepare for winter, a testament to the planting's success and its growing role in supporting wildlife. The visit took place during this year's NE2333 annual meeting.

Have seen a number of true wild, pure American chestnut trees damaged by black bear. These trees are large enough to survive multiple years of “attacks” by black bear.
Hopefully the damaged bark does not serve as a corridor for the blight to enter living tissue.
Are these engineered trees or crossbred?
This excellent article takes a deep dive into the history of the American chestnut, the science driving restoration efforts, and the communities helping make recovery possible. Be sure to read the perspectives shared by TACF Director of Science Jared Westbrook, Board Member Jim Searing, and PA/NJ Chapter member Mike Aucott. 🌳🌰

Thanks for sharing! This was a great article and we're glad to be part of the restoration efforts.
I have acreage, but no idea how to purchase these.
I will be pleased if a 100 ft, tall tree with a sweet chestnut can be developed from any of these approaches.
