[quote=Ekka;22355]I fixed that link up for you.
Here's what that doc wrote about wall 4.
That is some really cool stuff you ve got there. I knew it looked familiar so I dove into the Shigo section of my library and found it.
This is from the US Dept of Agriculture, Forest Service Ag Info Bul #419 titled, "Tree Decay, An Expanded Concept"
April 1979
I showed this incredible book with the most beautiful and descriptive illustrations to Dr. Shigo and he was amazed I had it and signed it on the front, "Dave Shaw, "Touch Trees" Alex Shigo (Sig) 9/7/97.
This was the beginning of Modern Arboriculture (approx) and part of why he was named the "Father of Modern Arboriculture" a few years ago. He was just a plant pathologist at that time for the US Dept of Ag.
The dramatic aspect of this was the dispelling of the "heartrot concept"
From the intro, ".....include the orderly response of the tree to wounding and infection-compartmentalization-and the orderly infection of wounds by many microorganisms-successions. The heartrot concept must be abandoned because it deals only with decay causing fungi and it states that these fungi grow unrestricted through heartwood after infection of fresh wounds. The heartrot concept emphasizes descriptions of decay causing fungi and types of decayed wood. It describes disordered wood and events that occurred in the past. The expanded decay concept emphasizes the order of a compartmented tree, the order of compartmentalization and the order of successions. Regulation of discoloration and decay depends on understanding compartmentalization and successions."
This changed how we look at and treat trees!
Shigo cut probably thousands of trees in half (lengthways!) while researching this theory that describes compartmentalization and all the thousands of hours involved that resulted in the CODIT model.
This is why it is hard to take some poster laying on the couch watching reruns of sitcoms eating a bologna sandwich (a similar effort) and comes up with changing one of the words of codit from decay to dysfunction or something like that, and at the same time says someone will come along and update, alter or somehow improve on this modern day genus theory and other revolutionary changes he made. I really wanted to ignore this but could not
