Maryland Chapter

Sugarloaf Mountain Orchard

The Maryland Chapter operates an orchard at the base of Sugarloaf Mountain in cooperation with Stronghold, Inc., which owns the mountain. Two orchards were started in 1970 with irradiated nuts. The orchards are described as the East Field and the West Field.   The West Field orchard is no longer in use.

East Field – Originally planted in 1970 with an estimated 1000 irradiated seeds. Most have succumbed to chestnut blight and phytophthora. However, some  27 remaining trees have been used as mother trees in our breeding program.  Also, a backcross orchard of BC3 seeds (Manahan 41 x AG247) and an experimental orchard to study hypovirulence were planted in 2007 . However, most of these trees have been killed by the blight, phytophthora or deer.

What a difference a neighbor can make. 🌳🌳 Our Director of Communications, Jules Smith, recently visited a 10+ year-old hybrid American chestnut covered in burs. Just out of frame is another hybrid chestnut that helped pollinate the tree, resulting in an impressive crop of nuts this year. It's a small but encouraging glimpse of what's possible as we work toward restoring this iconic species. #AmericanChestnut #Trees #Conservation #Nature #RestorationForestry ... See MoreSee Less

I heard one of the possible mistakes of the original disease progression of chestnut blight was taking all trees down with signs of blight and not giving trees a chance to demonstrate some resistance. Not sure if that was accurate but it's food for thought as we try to bring them back

My crop will be fair

Sorry to say, but mine took 3 to 4 years looking like this before it died. It's progressive.

What a wonderful day at TimberFest! 🌰

We enjoyed connecting with visitors and sharing TACF's mission alongside others who are passionate about forestry and conservation. One of the day's highlights was the unveiling of a chainsaw-carved statue exhibit crafted from trees brought down by Hurricane Helene.

As an organization who's national office is rooted in western North Carolina, it was especially meaningful to see these trees incorporated into an exhibit that honors both the impact of the storm and the resilience of our region. Thank you to everyone who stopped by to learn more about American chestnut restoration and the future of our forests.

Was this at the Cradle of Forestry?

We love our Bonner Scholars!Thank you, Bonner Scholars!
As we head into the fall semester, we want to take a moment to recognize and thank our wonderful Bonner Scholars for their time, hard work, and dedication to Meadowview Research Farms last spring semester! We are especially grateful to Gabbie and Maddy who graduated from Emory & Henry this past spring, who each served with The American Chestnut Foundation for more than two years. Their commitment and contributions have made a lasting impact on our research farm, and we are so thankful for all they have done! We also want to recognize Carson, who joined us last spring and has been an important part of our team. We’re excited that Carson will be continuing to serve with us this semester.
Thank you, Gabbie, Maddy, and Carson, for all of your hard work and for being such an important part of the Meadowview family. We wish Gabbie and Maddy all the best in their next adventures, and we’re excited to have Carson continuing on with us!
And an additional thanks to Meadowview Research Farms' Tree Improvement Scientist, Lucinda Wigfield, for her outstanding coordination and supervision of this important student group!

We love our Bonner Scholars!

The mysterious voice in this video might be onto something... 👀🌰

Looking for a research project idea? The American chestnut has plenty of unanswered questions waiting to be explored.

If your project touches on chestnut restoration, genetics, blight, ecology, biotechnology, history, or another chestnut-related topic, consider sharing your work at the TACF 2026 Symposium Poster Session.

Give your research an audience beyond the classroom and connect with others working to restore the American chestnut.
