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.

7901 Comus Road, Dickerson, Montgomery County

Contacts:
The Propers – Stewards
David Webster – Executive Secretary, Stronghold Inc.

Challenges: Deer, Phytophthora, gall wasps, vines.

Tissue sampling for recurrent genomic selection is no small task, but thanks to an incredible group of volunteers, we made it happen! Leaf samples were collected, placed in a small tube, and then a wraparound tag with a unique ID was placed on the tree; each unique ID corresponded with the tube the sample was put in. We had volunteers from the Washington County Master Gardeners, Washington County Master Naturalists, Emory and Henry University, and King University. Tissue collection is a key step towards advancing our breeding program, and we are incredibly grateful for everyone who showed up, worked hard, and supported the process. Science moves forward because of people like you! #americanchestnut #RestorationInProgress

From far away, it looks okay. Up close, and inside, it’s clear these barns can no longer protect the work of restoration. This Earth Day and throughout our Spring Appeal, help us raise the barn that supports the return of the American chestnut.

We had a great time at our recent spring meeting, part of which included a tour of Meadowview Research Farms for staff and our board of directors. We discussed current projects and the future of the recurrent genomic selection (RGS) program, and highlighted important infrastructure needs that will help support future growth and continued research efforts. Investing in these areas will be key to advancing our mission and strengthening the work being done. We could not have done this alone; thank you to everyone who participated and contributed to such a productive and inspiring day!

Good luck

To have the American chestnut tree back would be so great. I remember them. Yep, I am that old!

Would have loved to seen them when they covered the Eastern Forest , Great news on developing a blight and root rot resistant Chestnut
