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.

Join us on tomorrow, October 10, 2025, from 11:30AM – 1:00PM (EPT), for the next LIVE Chestnut Chat.

Our special guest, Dr. Trevor Walker, Assistant Professor of Forest Genetics and Co-Director of the Cooperative Tree Improvement Program at NC State University, will share insights from 70 years of breeding loblolly pine for disease resistance, growth, and stem form. He will also consider which practices are likely to succeed for American chestnut, which are not, and why.

Do you love pulling on your work gloves and cracking open freshly fallen burs to reveal the chestnuts inside? If you do, but don’t have any of your own yet, become a member and get access to our wild-type seed sale in 2026. In just a few years, your hands could be full of spiky burs and American chestnuts of your own. support.tacf.org/membership/new-regular ... See MoreSee Less

We’re proud to share this segment from the PBS show Human Footprint, featuring former TACF staff member Sara Fitzsimmons. The American chestnut sequence was selected to be adapted into a standalone YouTube video, which launched in late September and has already garnered more than half a million views. Sara’s dedication and expertise have shaped much of the progress in restoring the American chestnut. Give it a watch to learn more about this important work. ... See MoreSee Less

Great presentation!

🌰 Harvest season at TACF’s Meadowview Research Farms brings both beauty and breakthrough science. Many of the chestnut crosses we gather are generated through recurrent genomic selection—cutting-edge research driving restoration forward. Each bur holds not only the wonder of new life, but also the promise of a future where the majestic American chestnut returns to our forests. 🌳

Are there places we can purchases a Chestnut tree that is disease resistant? Thanks!

We'll be co-hosting American Chestnut Day at the NC Arboretum this Saturday! If you're local, we hope you'll join us for a fun day of speakers, activities, and even a wild-type chestnut seedling sale! ... See MoreSee Less
