L in our office used to wholesale hardwoods, and shared a story with us: in 1904, a fungal blight devestated the American Chestnut Tree, so from that year through 1920 all these trees were cut and stored for their wood. They were used to build barns, etc. until the supply ran out. Now, a century later, it is a highly valuable wood to use in hardwoods, since it is rare and often has to be reclaimed from old buildings, rivers (where old trees fell), etc. (I verified on Wikipedia that a blight wiped out billions of the “important” American Chestnut Trees). Wow! I had no idea.
