I was walking a section of the AT between Port Clinton and Windsor Furnace (in Pa.) today, and I was amazed at how many small American Chestnut trees I could see from the footpath. Hundreds, if not thousands! Most of these were under 10 feet tall. Yes, I know that the blight doesn't hit them until they are a little bigger than this, but I wondered: how are the native populations doing in areas where this tree had once been prolific? Some scientists who study this tree and the blight that affects them believe that some trees MAY develop an immunity to the blight at some future time. (I know of at least one on-going study taking place near Lancaster, Pa.)
