    I sent a sample of one of my trees to one of the labs listed on the web site that confirmed it was indeed a surviving Chestnut.Tried working with TACF rep in my area last year and he acted like he couldn't care less - flat out told me he wasn't interested. I have an 85 acre farm in Western NY that could be used for planting and research and was willing to let it be used as a research station..... Great to see the rest of your organization is more enthusiastic about the mission than he is...

    I live in northeast Massachusetts, and in one of the old cemeteries from the 1600-1700's in my town, towering above the graves of some Revolutionary war veterans is a huge American Chestnut tree that somehow survived the blight. It's an awesome sight, especially among grave stones that are over 300 years old.

    I planted about 50 nuts before I went into the army (fort lost in the woods) 38 are still going. The tree I got them from was over 4 arm spans around the tree. It got bulldozed under for a friggin well pad. One tree in the contract that was protected was that oneand the area 200 ft from it. The funny part is that cleared area is full of small saplings and the owner got 1 million fo rtaking out that tree.

    Three decades ago there was a lone single 40-50ft tall Chestnut tree growing in the Michigan woods my father would take me honey mushroom hunting in the fall. We would pick up a few chestnuts off the ground along with the honey mushrooms that grew in that woods. Later they started building houses there so that put an end too our good mushroom hunting woods. The woods are long gone now, and idk if the builders ever saved the Chestnut tree or it was cut down. American Chestnuts were so rare and not even native to Michigan, most people wouldn't have even known what it was, and i only knew because of my father. idk how a single American chestnut ended up in the middle of that woods, but it was there, and it's the only American chestnut i've ever seen in my lifetime.

    My information is dated. But I thought that they were about 120 blight resistant American chestnut trees that were found along time ago. If it’s eight years from seed to nut in locations that have adequate sunlight, has anyone tried just trying to continue to improve the American chestnut to become resistant to the blight? As in every 10 years a new seedling are planted until they don’t succumb to blight?

    @@Dollapfin I was involved in milling elm trees in England following the Dutch elm disease. It first hit our English elm as its preference but then moved on to the Wych elms. Most areas were effected. Scotland appeared disease free as the beetle that carried the disease could not stand the climate in winter. Other areas claimed to be disease free but gradually lost their remaining trees over an extended period of years. The roots that remained readily produced young sucker growth which can reach maybe twenty years old and suddenly dies. The beetle is still clearly present as the egg galleries can be seen under the bark once removed. It's a losing battle to reintroduce if they can't get every landowner to comply and grub out every root and stump. You will almost certainly find a similar scenario as you pray for Darwins theory to kick in. Great a new tree subvariant that has appeared to be resistant! What makes you think the pathogens that cause the blight won't do the same. Ever heard of Covid.

    The ability to break down the acids the the blight produces. The wheat plant has this gene that has been spliced into surviving American Chestnut. It has been very successful in producing blight resistant trees. It must be approved by the Government before it is re introduced. About ten years. It is as harmless as the Tomato, strawberry, corn or other genetically altered plants. This type of back crossing is not working. This type of cross and back breading is not ever going to work. The genetically spliced trees are completely resistant to blight.

    @@joanhuffman2166 The blight is from Asia and Europe. The Trees from there have evolved with the blight. The blight still can kill them. Unfortunately American chestnut trees have no natural resistance to the fungus because the American trees did not evolve with the fungus. Think of the Blight fungus as Malaria in Humans. People who live in areas with Malaria have a natural resistance to the disease. Malaria can still be fatal even if you have been exposed to it you entire life. If Americans go to an area with Malaria we will die without the proper medication. America eliminated malaria before 1900. We now have no natural immunity to the disease. This is the best explanation I can come up with. Hope this helps.

    Shouldn’t we get rid of all the Chinese chestnut trees, which brought this disease over with them? Do all Chinese chestnut trees have this disease and just resisted it? If so, they should all be cut down and burned. It definitely seems that the blight doesn’t do as well in killing trees in colder climates. I don’t think those trees are superior in any way. The blight just thrives in warmer climates and is more effective. Other questions: Does this blight survive in our soils for years after the Chestnuts trees are gone? Does the blight affect other trees? Is there a way to kill the blight in the soil, where a chestnut tree once lived and died from it? How does the blight spread?

    This is just buying time. Take a genetically engineered small tree, engineered to be sterile. Graft it to a surviving root. As the graft takes, it will grow large enough to provide energy to the root, which is purely American chestnut. This will stave off extinction. Eventually some technology will come along that is a combination of effective and acceptable.
