  • At the beginning, some doof misspelled "wooly" -- that's kinda funny for an academic video like this.... Hehehe.....

  • I was just in the Smoky Mtn. Nat'l Park & the devastation there is growing. Frasier fir-gone, Red Spruce- 1/2 gone, Balsam Fir-gone. Eastern Hemlock- getting tore up and many of the giants are even significantly dying back. Foliar sprays are not having an impact from what I see.
