American chestnut on the Appalachian Trail

I was reminded this past weekend while hiking the Appalachian trail along the CT / MA border of what it must have been like a hundred years. Every so often our little hiking party would find ourselves under a spreading canopy of American chestnut leaves. A hundred years ago, when most of the trees were large American chestnut, this would have been the expectation. Today this is an unusual though not unknown treat.

Two weeks ago I took my retriever for a quick hike along the trail and ran into some kids from the AT conservation maintenance unit. We got talking and realizing I would pass them again on my way out, I planned a little discussion on trees. I grabbed three different leaf samples: Chestnut Oak, American beech and American chestnut to show the kids and compare and contrast the leaves and talk about the similarities and differences of both the leaf morphology as well as tree ecology. I expected (and indeed it happened) that this would lead to an opportunity to discuss the trees life histories as well. These kids and their leader were more than up to the discussion (it was a sulty 85 degrees and they welcomed the break) and were thrilled to learn about the chestnut and that they were working in close proximity to so many remaining sprouts. One of them even knew that the three samples came from the same family … fagacea … which thrilled me as you can imagine.

I hope that more young people take an interest in caring about the outdoors like these conservation workers. I hope that more kids and people learn about the ecological disaster that was the chestnut blight … and that people can take steps to right a wrong, like The American Chestnut Foundation is doing with the chestnut.

A major milestone for conservation science.

Our Director of Science, Dr. Jared Westbrook, has published new research in “Science” showing how genomic tools can transform endangered species recovery. By using recurrent genomic selection, we can predict resilience earlier, shorten breeding cycles, and build a restoration system that grows stronger with every generation.

This model doesn’t just help the American chestnut, it could guide restoration for threatened species across the world.

Across the world...is that like around the world?

Anyone have any links or information about Iodine use soil/spray and duration for eradicating or postponing the fungal infection? All the research I've done shows Iodine could cure the infection if using science.

Would this work for the American elm tree?

We’re honored to be highlighted in this AVLtoday feature on the American chestnut’s story in Western North Carolina.

While the path to restoration is long, moments like this remind us how many people care about bringing this tree back to the landscape it once defined.

Thank you to everyone who continues to help this story grow.

Is the photo a back crossed hybrid of American chestnut and Chinese chestnut?

Freedom seekers—enslaved Africans and African Americans who escaped slavery in pursuit of freedom—faced hunger, exposure, and unfamiliar terrain as they journeyed north.

Black History Month provides an important opportunity to honor the past while also recognizing how Black knowledge, leadership, and community continue to shape the present. From histories rooted in land and survival to modern platforms and outdoor spaces where connection and representation matter.

Throughout February, we will share a series of four stories that explore Black relationships to land, legacy, and community, looking at both historical foundations and contemporary expressions.

Hopefully they will be developing a mold resistant tree.

That's a really interesting perspective. I think a lot of woodcraft and other types of knowledge about the natural world, like astronomy, had to be shared. Also, marine skills.

Chestnuts?

January might feel like the quiet season, but at our research farms it’s already time to get growing. This month, we’re sowing chestnut seeds that will be used in upcoming research and breeding efforts. Starting seeds in January gives us a valuable head start on the growing season, allowing seedlings to establish early and be ready for genotyping in the spring and summer. Each seed represents an important step forward in our research, helping us better understand growth, resistance, and performance across chestnut species and hybrids. #AmericanChestnut #RestorationInProgress
