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.

There’s nothing quite like the first signs of life in the nursery; our chestnut seedlings are officially emerging! After weeks of careful stratification, planting, and patience, we’re starting to see those first tender shoots break through the soil. Early seedling emergence is a critical stage, showing us that germination was successful and that strong root systems are beginning to establish beneath the surface. These seedlings will be used for our Recurrent Genomic Selection program, including future seed orchards, progeny tests, small stem assays, phytophthora root rot screening. Here’s to healthy growth, strong roots, and a thriving season ahead! #AmericanChestnut #RestorationInProgress #ChestnutResearch #ForestRestoration #MeadowviewResearchFarms #ConservationScience

Meadowview for the Win!🏆
Grafting is one of the tools we use to conserve large, surviving American chestnut germplasm and ensure it isn’t lost. By grafting scion from important trees onto compatible rootstock, we can preserve valuable genetics and share this germplasm across regions. This work allows exceptional trees to live on in multiple locations, supporting research, restoration, and collaboration while safeguarding the diversity of the American chestnut for the future.

Our Director of Science, Jared Westbrook, was interviewed by Ira Flatow, founder and host of Science Friday, for their podcast. The episode is now available: www.sciencefriday.com/segments/restoring-american-chestnut-tree/
On Science Friday, Jared discusses the multiple approaches taken to improve blight resistance in American chestnut trees, TACF’s recurrent genomic selection program as our main engine for restoration, and what successful restoration looks like.

Black History Month provides an important opportunity to honor the past while also recognizing how Black knowledge, leadership, and community continue to shape the present. From histories rooted in land and survival to modern platforms and outdoor spaces where connection and representation matter.
Today we’re highlighting Hattie Carthan, who fought against the impacts of redlining and disinvestment by mobilizing her Bed‑Stuy community to restore its trees and protect a landmark magnolia. Her legacy shows that restoration starts with us, an idea at the heart of our work to revive the American chestnut.

So trees DO grow in Brooklyn again?!
Our air pruning bed was constructed in early 2025 and has since been growing hybrid chestnuts that play an important role in our grafting work. Air pruning beds allow us to grow strong, well-branched root systems and make it easy to access high-quality rootstock for grafting. MRF staff are currently grafting using the root stock from trees that were grown in this air pruning bed, so stay tuned to learn more about it next week!
