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.

Great video, keep them coming.

Thanks. I have one from OIKOS that was advertised as 95% American. Here's the trunk -- alittle blight on the lowest branch at left, but that's been yrs ago and has healed over. It's been putting out male pollen racemes, but they don't open (become fuzzy) -- don't know why.

Transgenic American Chestnuts are still a much better option. The product of this method will always be a hybrid and that should not be the goal.

One of the greatest ecological disasters the US has ever seen. Chestnut blight wiped out the American chestnut tree in less than 50 years.⁠
A tree that once made up nearly 25% of the eastern forests was reduced to a functionally extinct species.⁠

The Asian fungus Cryphonectria parasitica was accidentally introduced into the United States in the late 1800s. While a few diseased chestnuts were noted in the 1880s and 90s, it wasn't until 1904 that the pathogen was identified in New York City. From that point, the blight spread rapidly. By 1950 the entire range had been consumed.⁠

The fungus causes cankers that spread around the trunk of the tree, girdling it and killing everything above ground. Many root systems still survive today and continue to send up shoots, but these also eventually succumb to blight. Because American chestnuts rarely survive long enough to reproduce, the species is considered functionally extinct.⁠

The American Chestnut Foundation is working to develop blight-resistant American chestnuts that can be used to restore this iconic tree to its native range. Learn more at tacf.org/about-us (link in bio)

I think I may have found an American Chestnut tucked away in a backyard

Incredibly important work…it was such a travesty for our forests!

The trees seem to still be intact outside their range in isolated areas. Theres a few large ones here in central Michigan on a peninsula and again on the Leelenau peninsula in the nw lower peninsula. I keep seeing people chime in about adult trees here and there. Seems like there's hope!
