2008 Pollination Report

This summer, after five trees we hoped to pollinate did not work out, we went forward with creating lines from four new trees and made two re-pollinations. Between June 16 and June 29 flowers were pre-bagged to protect them from stray Chinese or hybrid chestnut pollen. Controlled pollinations were done June 27 to July 11, using pollen from selected third backcross trees at TACF?s Meadowview Research Farms.

Board members Robert Gregg and David Bingham produced the year?s best results. Robert went aloft in Ken Fries? bucket truck and performed the bagging and pollination of a tree on his property. Although only 14 bags could be placed, Robert averaged 1.8 fertile nuts per bur, harvesting 34 nuts. Next year he plans to complete the line. David spent many hours up on ladders as he also did all the pollination work himself on two trees. He brought in the biggest harvest, 88 nuts from the Old Lyme Library tree. David also finished the Salem line with an additional 18 nuts.

At Lockwood Farms in Hamden, Dr. Anagnostakis gave permission for TACF Regional Science Coordinator Leila Pinchot to pollinate a pure American tree that was planted in 1988, kept alive with the help of hypovirulence. This tree is the offspring of a tree found in Norwich. TACF Regional Science Coordinator Kendra Gurney did the harvest, but found squirrels had torn into the bags, reducing the harvest to 35 nuts.

Our Tolland and Litchfield mother trees were very badly blighted, but Bartlett Tree Experts was willing to donate their time to give the trees a chance. Mike McGee had found the Tolland tree and worked with the owner to coordinate the pollination, and I assisted with Tolland and coordinated Litchfield. Unfortunately the Tolland tree?s cankers cut off nourishment to most of the tree before the nuts were formed, so only two fertile nuts were found in the bags. The Litchfield tree did slightly better, but its topmost branches holding many bags died back. Within the twelve remaining bags were 23 nuts.

We are looking forward to completing our twenty lines of Clapper resistance backcross trees in 2009. Our board members will be busy come late May through early June next year, checking twenty reports we have received of potential mother trees in Connecticut!

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!
