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.

Did you know some plants actually benefit from fire? Recently burned areas often provide the sunlight and reduced competition that species like blueberries and American chestnuts need to flourish.

Yes! Across the Eastern US, almost all of our most important keystone , overstory trees are fire adapted (pyrophytic 🔥). (Except in bottomlands/riparian/wetland zones, for the most part). This includes Hickories, the upland Oaks, certain pines, especially Longleaf, and Chestnuts. Many Oaks in particular are struggling with recruitment now due to fire suppression, among many other issues. This process is called mesophycation btw. Mesophytic natives like Maples 're-engineer' forests through their dense, moist leaf litter to retard-fires. Invasives make it worse. This is important because Oaks are THE top keystone plants here, hosting more species of Lepidoptera (Moths and Butterflies) than any other plant genus in the US: 500-900 species. Most of these caterpillars will become inconspicuous "little brown moths" , but they form an important massive bottom-tier of the food pyramid. After all, even though birds can source berries from a variety of plants , it takes 6-9000 caterpillars to raise a single clutch of songbirds.

I really appreciate what you are doing.

Thank you!

Just a few years apart: the same wild American chestnut tree before and after chestnut blight took its toll.
