I just got in and checked my e mails to find Shigo has died this morning. For those of you who don't know the name he was the father of modern Arborculture. He dissected trees, studied all parts of the tree from the roots to the canopy and really changed the industry standards. As a young forest ranger he climbed into the canopy and tied himself to the trunks of trees during storms to study how they moved. A real pioneer in the industry he will be missed. He apparently he fell down some steps and hit his head and never regained conciseness.
