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.

If you’ve ever wondered why we keep planting wild‑type American chestnuts, even though they eventually succumb to blight, this is why.

Any other questions we can answer? Drop them in the comments!

Maybe one will mutate and not get the blight .

I had a co-worker who was experimenting with this 20 or 30 years ago. He dug up the soil from the base of the tree and made a poultice. At the time, I didn't know a Chestnut from a ham sandwich. Now I have a dozen of my own stump sprouts and am planting four of their genetically selected trees this year.

The Canadian chestnut council initiated the blight resistance breeding program and planted out these trees in 2020. We fortunately have collected seeds and propagation of these seedlings are available at the Little Otter Tree Farm Tillsonburg Ont

Rogueing has officially begun! Late last year, Meadowview Research Farm staff selected the best trees in our 2018 progeny test to be genetically tested this year, and now our Director of Land Management, Dan McKinnon, is removing the trees that weren’t selected. The 2017 progeny test is also being cleared to make way for future plantings. Removing undesirable trees on a regular basis provides space for the trees of tomorrow.

if you dug them I am sure some of us could plant them.. i mean if there is a chance they make it

Can't you replant the "undesirable " trees else where as they're important to the earth breathing.

Thanks, Dan!

Sorry I will miss this! I have to be at our SAWN-PA forest workshop.

In collaboration with us, the off-road park, Anthracite Outdoor Adventure Area (AOAA), has participated in planting American chestnut trees across their property.

"Off-road parks do not always have a reputation for environmental stewardship, which makes AOAA’s conservation work genuinely surprising and worth highlighting."

TACF’s Director of Development, John, and Director of Communications, Jules, had a great time tabling at an event for the one-year anniversary Tree Museum Birthday Gala. Despite the rainy weather, the gala planted trees, roasted chestnuts, and hosted a ticketed “Tree Walk” that sold out.
