Ohio Chapter TACF Small Grants Program
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’re thrilled to see Backpacker shining a light on the American chestnut and TACF’s work to restore this mighty tree. 🌰 Read the article here: www.backpacker.com/stories/american-chestnut-trees-comeback/

We could do with these being used in England for future forestry projects. The Pennines would make good habitat for them after the peat moorlands burn out. This is now inevitable thanks to the Labour government banning controlled winter burning with the intent of banning grouse shooting. Also Labour and Conservative governments alike failed to seal our borders against chestnut blight despite it being rife in France. Good old EU deflections of responsibility.
What's the difference between the American Chestnut and the Chinese chestnut tree? I recently planted 7 of the Chinese variety.
It can be tricky to tell the difference between various chestnut varieties. In this video, TACF staff membe Angus shows the differences between Chinese chestnut leaves and stems and American chestnut leaves and stems.

Nice details. I can easily confirm exactly what you’re sharing. We have both on our property. TY
I'd love to see one of European or dunstan VS American
Thank you! Can you do a breakdown of the chestnuts themselves too??
Getting involved in your local state chapter is one of the best ways to support the American chestnut, and a great way to get access to seeds and seedlings! Visit tacf.org and select "Chapters" to learn more.

Are we able to genetically recreate the original?
Are these edible by humans?
So your having a professor from the UofI Urbana/Champaign give a talk chestnut genetics but you don't have chapter in Illinois🤷♀️?
🌰 Over the course of this year’s harvest season, more than 20 volunteers from Emory & Henry University, King University, Master Gardeners, and Master Naturalists joined us at TACF’s Meadowview Research Farms to help process burs and collect seeds for the next generation of American chestnuts. Together, they shucked over 17,000 burs, yielding over 30,000 seeds that will support research, our partners, outreach events, as well as our RGS program. 🌳
Their time, energy, and commitment make an incredible difference in the success of our restoration work. As the 2025 harvest season officially comes to a close, we’re deeply thankful for our volunteers and partners — this effort wouldn’t be possible without you! 🍂

What about the Beetles? The ones I picked here ended up being full of them.
Thank you!
I want plant some on my farm were should i get them?
🌰 It’s National Nut Day! 🌰
What better way to celebrate than by helping restore the most iconic nut tree of them all: the American chestnut.
When you donate $25 or more to our End of Year Campaign: One Tree, Many Hands between Oct 22–31, you’ll be entered for one of three chances to win a Seed Level membership with The American Chestnut Foundation! 🌱
Seed Level members receive a subscription to Chestnut magazine, early access to wild-type seedling sales, and four chestnut seeds with intermediate blight resistance, a gift that helps grow the future of this iconic tree.
Visit support.tacf.org/2025-end-of-year for your chance!

Can anyone tell me which species of Chestnut this is? It is growing at the edge of the Heard Farm meadow in Wayland, MA. The tree is maybe 40 feet tall.
Looking for chinquipan trees or seed. Anyone help me?
