Ohio Chapter

About Us

Our Mission

The Ohio Chapter was founded primarily to bring about the restoration of the American chestnut throughout the hardwood forests of Ohio, where it once flourished. We work with the National Foundation to advance research, education, and public awareness of this important tree species. The Ohio Chapter implements this mission by education and research. Education would include projects such as establish demonstration plantings to acquaint people with the American chestnut and the blight that has almost eliminated by the blight, providing material for education, provide grants to support demonstration plantings and presenting information at appropriate forums. Research would include mine restoration plantings with American chestnuts, reforestation projects including American chestnut, test plantings of hybrid American chestnuts, finding and document surviving American chestnuts in Ohio, and supporting chestnut research in Ohio with grants.

American Chestnut in Ohio

The range of the American Chestnut was mostly restricted to the glaciated and unglaciated Appalachian Plateau region In Ohio. This is roughly the eastern half of the state. The chestnut grew mostly as part of the oak hickory forests and constituted 10-20% of the forests in eastern Ohio. They reached3-4’ DBH. Since Ohio is in the western part of the range the of the tree the blight did not completely decimate the chestnut in Ohio until the early 1940’s. Some large snags persisted for awhile but now almost the only thing left are root sprouts in the understory of the forest and ODNR now lists the American Chestnut as extirpated in Ohio.

Ohio Chapter of The American Chestnut Foundation

The Ohio Chapter of the American Chestnut foundation was established in 2005. The mission of the Ohio Chapter is to support the goals of the TACF through research and education to restore the American Chestnut to its former glory. Education includes demonstration projects to increase awareness, presentations, and publications on the American Chestnut. Research efforts include restoration projects, finding surviving trees in Ohio, and sponsoring research supporting the restoration of the American Chestnut in Ohio and throughout its range.

It's time to get growing this week at Meadowview Research Farms! Alongside seeds harvested from Meadowview Research Farms, we’re also planting seeds sourced from partner pollination programs across the American chestnut range. The seeds have been stratified in coolers since being harvested last fall. The process of stratification in coolers mimic natural conditions of moisture and cool temperatures to prepare them for germination. Each seed is carefully placed into its designated pot based on its experiment, covered, and watered in—officially beginning the germination process! Come back and check out the progress soon!

For all you chestnut nerds out there, here's a great read!

From the abstract: Over a century after two introduced pathogens decimated American chestnut populations, breeding programs continue to incorporate resistance from Chinese chestnut to recover self-sustaining populations. Due to complex genetics of chestnut blight resistance, it is challenging to obtain trees with sufficient resistance and competitive growth. We developed high quality reference genomes for Chinese and American chestnut and leveraged large disease phenotype and genotype datasets to develop accurate genomic selection.

I hope there is a real breakthrough in my lifetime

Is there any ai programs that you can feed the dna of each tree and ai will tell you which crosses will do best to increase resistance on each cross ?

Is it true that the American Truffle mycelium help the trees fend off blight?

Over the past few days, the Meadowview Research Farms team has been hard at work preparing pots to sow seeds for this year's experiments! These seeds play a vital role in Recurrent Genomic Selection, Small Stem Assays, and other trials. With a greenhouse capacity of over 5,000 trees, we’re ready for another year of innovative research. The pot-filling process begins with adding fertilizer to the growing media and filling each pot to the top, ensuring they are ready for sowing. Once all the pots are filled, the tagging process begins. Each pot receives a label indicating its tree ID, genotype, and corresponding experiment. The tagging process is critical as it helps differentiate each pot's journey and helps maintain organization in the greenhouse. Stay tuned for the next post on sowing!

Join Lauren as she demonstrates the process of the Generational Passthrough experiment. It starts with the initial inoculation and placement of cryphonectria plugs into young seedlings. She then observes the cankers' development over a two-week period. Next, Lauren extracts the cryphonectria from these cankers, trims and sections the stem into agar for culture and subculture, repeating these steps across ten generations. Finally, she examines the initial and final cultures, where the genome sequence provides crucial insights into the changes of the cryphonectria. Lauren's analysis aims to detect any genotype alterations in the chestnut trees and observe potential evolution in the cryphonectria.

Come back and check out our next post on “Follow the Roots”!

At Meadowview Research Farms the chestnut orchards go dormant in the winter, but any seedlings that haven't been planted are allowed to go dormant as well! Potted seedlings are "overwintered" to protect their roots from freezing, ensuring they survive to the next growing season. Trees in the field are insulated from the frigid temperatures by the thermal mass of the soil surrounding their roots, but seedlings do not have the same protection being in small pots. MRF places trees closely together inside of thick vinyl tents to protect potted seedling roots from the low temperatures outside and adds heaters for particularly cold weather. Seedlings for certain research projects also remain dormant indoors in garages that are kept at 40 degrees Fahrenheit throughout the winter. The temperatures have remained consistently low for the past few weeks, but the seedlings are happily waiting out the winter for the next growing season to arrive.

Fascinating info!

I messaged the Carolinas chapters. The last activity was Dec 2023 though . I’d like to plant some chestnut trees around my property but can’t afford the 300 dollar fee/ donation. Could I just get a few ?

I like to say that they've gone to winter quarters.
