Mt. Riga Chestnuts

By Ellery Woods Sinclair
Member of the Board of Directors
CT Chapter of The American Chestnut Foundation

This past spring Christine Cadigan, the chapter's intern through a Duke University grant, and I scouted Salisbury's Mount Riga to find an accessible mother tree. I knew that Riga had an abundance of chestnut trees, especially root sprouts. Slowly driving up the mountain, we saw many small trees over-hanging and some back from the road under the forest canopy.

Up on the top, a fine, easily accessible chestnut beckoned to us with golden catkins. About thirty feet tall in full sunlight, our specimen provided a clipped branch tip for verification as American.

Before spring was over, our Bartlett Tree Expert backed in the cherry picker to prepare the tree for pollination. A few weeks later he returned (after careful hand pollination) re-bagged the tree as Christine and I watched in the pouring rain.

The nearly forty bagged branch ends — including four not-pollinated controls — waved in the breeze waiting (as pictured) until fall when the pollinated burs would be ready for harvest. In early October I met our Bartlett Tree Expert — Christine having returned to her studies. He clipped the bagged branch tips containing the burs, all required a few more days to ripen by hanging in my cool garage safe from rodents. In about two weeks those Riga mother-tree burs produced thirty-seven nuts, providing the foundation for a new line for our Connecticut orchards.

At the Great Mountain Forest orchard in late September I presented — as orchard manager for the CT Chapter of The American Chestnut Foundation in association with the Berkshire Litchfield Environmental Council — a program for the Housatonic Heritage Walks. One of their many programs, the American Chestnuts Lost and Found presentation was well-attended (as pictured) by those interested in the history regarding the loss of this valuable hardwood and the rationale for and method of bringing the American chestnut back to forest our landscape again — until a century ago, a primary tree.

The Great Mountain Forest orchard, maintained in partnership with the Housatonic Valley Regional High School Ag/Science Department students, contains about 300 saplings (15/16ths American & 1/16 Chinese from the back-cross generations) awaiting selection and the first inter-cross generation procedure in five to seven years.

The reward of this endeavor is it's being about the future, rooted in the past. In another half-century our great grandchildren will harvest the nuts and the timber, as did their forbearers a hundred and fifty years ago and before.

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!
