CT-TACF Begins Backcross Breeding Program in Enfield and Woodbridge

On June 11, CT-TACF met at White Memorial Foundation in Litchfield. Dr. Philip Arnold, Dr. Robert Gregg and Town Selectman Joe Callistro, active also in the Woodbridge Land Trust, shared their plans to work with Dr. Charlotte Zampini of MATACF to pollinate two 8-9 inch DBH, 40 foot tall trees in Woodbridge. Last summer I found two flowering chestnuts plus a larger “third tree”(healthier but not in bloom) in Enfield, and presented a poster picturing them. During the break, TACF President and CEO Marshal Case asked me which Enfield tree might have potential for pollination. I replied the nine inch DBH “third tree” might bloom well this year, but the other two were now in poor condition.

Fortunately, the owners of this Enfield tree, Paul and Cheryl Pavlakis, were willing to help, graciously allowing me access for photos and notes. It became apparent their tree would put on quite a show of catkins, but from the ground I couldn?t see if many female flowers were forming. After reading pages from TACF national and state chapter websites describing pollination procedures, I reached out to the TACF network for guidance. I wanted to learn as much as possible about the procedures and time them correctly. MA-TACF members Charlotte Zampini, Yvonne Federowicz, Kathy Desjarden and Rufin Van Bossuyt offered practical tips about supplies and methods. Dr. Fred Hebard reviewed my telephoto pictures of the flowers and gave detailed answers to questions. Blair Carbaugh of PA-TACF and TACF Tree Breeding Coordinator Sara Fitzsimmons shared advice. Daphne and Marshal at Vermont headquarters sent encouragement plus some leftover Shaftsbury pollination bags! Jim Gage, also a member of the Northern Connecticut Land Trust, volunteered to help on site. Pre-bagging was performed on the Enfield tree on a showery June 28 (yes, plenty of females up there); in late June in Woodbridge, eighty-seven year old Dr. Bob Gregg went up in the bucket with arborist Ken Fries and bagged the flowers on the Callistro tree. On July 8 both Woodbridge and Enfield trees were pollinated despite threats of heavy rain from remnants of Tropical Storm Cindy.

Dave Goodson and Robert Allen of Connecticut Light and Power (CL&P)/Northeast Utilities provided the key to getting the Enfield pollination effort “off the ground” by scheduling the Davey Tree Experts bucket truck crew of Al Vancour, Bill Murray and Les Richardson. Thank you Northeast Utilities for a very generous donation! CT-TACF also thanks Ken Fries, who arranged for the bucket truck to access the Gregg and Callistro trees.

We greatly appreciate the dedication of Dr. Charlotte Zampini, who drove in from eastern MA for the 7:30 a.m. Enfield pollination, then went directly to Woodbridge to work on their trees. Thirty-five bags were pollinated on the Enfield tree, plus sixty bags total on the two Woodbridge trees, a possible harvest of 150 – 175 fertile nuts. The resulting CT generation will be third backcrosses. Our chapter awaits the nut harvest and the first seedlings combining Connecticut and TACF blight-resistant chestnut genes. We appreciate the contributions of each individual who made this possible.

Seed prep is underway! Meadowview Research Farms staff and Emory & Henry Bonner Scholars are currently bagging seeds that will be sent to TACF Seed Level Members next week. These hybrid chestnut seeds are collected from genomically selected mother trees at Meadowview Research Farms and are one of the only ways to get seeds from TACF. Each seed represents a step forward as we prepare them for distribution to our seed level members; thank you for helping grow the future of the American 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.

Would this work for the American elm tree?

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.

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.

I thought American chestnuts didn't have hairs on them or shiny leaves. Is this a chinese hybrid?

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
