Nut-grafting!
January and February are the best times to cut scions from American chestnut trees and graft them onto American chestnut nuts. If they grow, you will have a clone of your scion wood tree that can be planted in a new location. Carl Mayfield, shown above, is an expert on this method of propagation. He graciously allowed us to take video at his nut-grafting clinic last winter, and he wrote out detailed instructions for every step of preparation and nurture, which can be found here:

Josh Roudebush win it all bro I might know a few big boys for the shot
A bee enjoying a well deserved break after the chestnut pollination period. The tree it rests on is a hybrid castanea pumila x alabamensis (dwarf chestnut x Alabama chinquapin).

In a recent article for The Conversation, Dr. Steve Strauss discusses how advances in genomics and biotechnology are creating new opportunities to support chestnut restoration.
We're pleased to see perspectives from a longtime TACF collaborator. Steve served on our Science Advisory Review Committee in 2018 and currently has a pending proposal with TACF to improve genetic transformation methods for chestnut.
Give the article a read and let us know what part of chestnut restoration you're most excited about: theconversation.com/new-genetic-approaches-raise-hopes-for-restoring-the-american-chestnut-to-its...

Somewhere, waiting discovery deep inside the remote part of a forest towers a thriving blight resistant nut filled American Chestnut (surrounded by dead ones just so we know it was exposed and surviving). We can hope. Taking inspiration from the Dogwood saga.
Professors at S.U.N.Y E.S.F put a wheat gene in to Chestnuts years ago and have growing them
I thought the blight only killed the tree above the ground and not the root system that's why the chestnut resprouts and grows until it gets a scar on it and the blight kills the sprouted tree back down to the ground leaving more viable root system to sprout again in the future.
Unlike most forest trees that rely mostly on wind, American chestnuts recruit insects too.
