Jerry, First let me say thank you for the fantastic pictures. Allowing people who have never seen these to catch even a glimpse is a real gift.
Sillett's work does indeed reek of a current trend in arbor academia world wide. The ideas of fracture pruning, retrenchment and veteranizing of trees has taken hold. I find this very disturbing.
Many of you who have spent time in the woods understand that man's presence does not improve things. We may not understand the need for forest fires, large scale beetle infestations, but there is a natural flow of movement throughout the forests that we cannot change.
It is in our nature to strive for betterment and also to feel that we (each individual) knows the correct way of doing that. I would suggest keeping that line of thinking to one's own life and let the forests be.
My formal education is severely lacking but I have wandered the deserts of the southwest, I have lived in the redwoods, and I have walked the tundra north of the artic circle. The only part of my life that had more of an effect on me than trees were the wild reaches of nature itself. The places I found the most fantastic had no foot prints of man and I believe in the philosophy of the American Indian, to walk and leave no trace.
