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.

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!

PICA, the Printing Industry of the Carolinas Awards, is celebrating its 60th year as the ultimate showcase of excellence in printing, and TACF has something to celebrate too.

Our partner in printing (BP Solutions Group) has entered Chestnut magazine in this competition for nearly 10 years and of those, TACF, BP, and designer Lisa Alford have received an award nearly every year, some of which included multiple awards within the same year!

Chestnut once again received a PICA Award for the 2025 competition, winning “Best of Category” for its “Sheetfed Magazine Series.” TACF is thrilled to have received this honor and to celebrate it with you!
