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.

Great video, keep them coming.

Thanks. I have one from OIKOS that was advertised as 95% American. Here's the trunk -- alittle blight on the lowest branch at left, but that's been yrs ago and has healed over. It's been putting out male pollen racemes, but they don't open (become fuzzy) -- don't know why.

Transgenic American Chestnuts are still a much better option. The product of this method will always be a hybrid and that should not be the goal.

One of the greatest ecological disasters the US has ever seen. Chestnut blight wiped out the American chestnut tree in less than 50 years.⁠
A tree that once made up nearly 25% of the eastern forests was reduced to a functionally extinct species.⁠

The Asian fungus Cryphonectria parasitica was accidentally introduced into the United States in the late 1800s. While a few diseased chestnuts were noted in the 1880s and 90s, it wasn't until 1904 that the pathogen was identified in New York City. From that point, the blight spread rapidly. By 1950 the entire range had been consumed.⁠

The fungus causes cankers that spread around the trunk of the tree, girdling it and killing everything above ground. Many root systems still survive today and continue to send up shoots, but these also eventually succumb to blight. Because American chestnuts rarely survive long enough to reproduce, the species is considered functionally extinct.⁠

The American Chestnut Foundation is working to develop blight-resistant American chestnuts that can be used to restore this iconic tree to its native range. Learn more at tacf.org/about-us (link in bio)

I think I may have found an American Chestnut tucked away in a backyard

Incredibly important work…it was such a travesty for our forests!

The trees seem to still be intact outside their range in isolated areas. Theres a few large ones here in central Michigan on a peninsula and again on the Leelenau peninsula in the nw lower peninsula. I keep seeing people chime in about adult trees here and there. Seems like there's hope!
