Prowl, I had some time last evening before I headed upstairs and I did a search on the American Chestnut tree (Castanea dentata). I read several articles and I learned more than I ever knew, but I also learned that my wife's stepdad had told me much of what I read about. There was one article by a fellow who said he was a naturalist and he came down pretty hard on whoever it was that introduced the Asian chestnut variety into this country in the very early 1900's. I recognize that it shouldn't have happened, but I have the benefit of hindsight and know what happened as the result. It was from those trees that the blight was introduced that destroyed the American Chestnut as they were known. My wife's stepdad was a nurseryman and raised nut trees including the Chinese Chestnut (Castanea mollissima). I also saw where there were people that had young trees (American Chestnut) for sale that were taken as suckers from the roots of trees that had been lost to the blight. But they have been working on trying to save the American Chestnut for many years and so far any tree from roots of affected trees have also been afflicted with the blight and will die. There is a thing they are doing though with introducing some cells from the Chinese Chestnut which is blight resistant into the American Chestnut and this is showing some promise of success. The result will be a hybrid, but will almost be 100% American Chestnut.
