I finally got an annual pass to Biltmore. There is an oustanding collection of trees on the grounds, even Douglas Fir and Dawn Redwood. There is a Rucker index for the grounds already but I did a little measuring in some groves near the house and the statue of Diana. Hemlock groves are doing extremely well. It appears that the groves near the house and gardens have all been treated entirely and the trees nearest the approach road have been as well. Some groves of a dozen to a few dozen were entirely healthy and the largest grove I saw had only about 10% mortality. I assume Will was involved due to the high rate of survival.
