There are quite a few of the remains of blight killed trees that resprout around us. Some develop enough to produce nuts. There are also quite a few that grow from the nuts produced that the bears, deer and turkeys miss. And yes, these are American chestnut, not Chinese and certainly not horse chestnut. The ACF and others have some stands locally where they are trying to breed for resistance in pure Americans.
As for the trees I referred to growing & fruiting, I've seen lots of them that get 20 to 30 feet tall before getting killed off. They are persistent and perhaps this may one day pay off with a naturally selected blight resistant tree.
