(April 2020) (Learn how and when to remove this model message) Dr. Alex Shigo (right) explaining the markings on an oak section during one of his last symposia. Alex L. Shigo (8 May 1930 – 6 October 2006) was a biologist, vegetable pathologist with the U. S. Forest Service, whose studies of decay of trees have led to many improvements to standard arborealistic practices. He traveled and lectured to promote the understanding of the biology of trees between tree-tree and forest. Its large primary research body serves as a broad basis for further research in tree biology. [1] Biography Shigo was born in Duquesne, Pennsylvania. He was a clarinetist with the United States Air Force Band in Washington DC for four years during the Korean War. After his service, he graduated in Biological Sciences at Waynesburg College in Pennsylvania, then a doctorate in Plant Pathology at West Virginia University in 1960. [2] [3]joined the United States Forest Service as a tree pathologist. He served as chief scientist for 25 years and retired in 1985. Shigo wasfor his defensive and philosophical style when he writes and speaks, and for his marked phrase, “all trees”, with which he autographed his books. Research At the beginning of his career, the first chainsaws of a man became available. These allowed him to prepare longitudinal sections of trees, which allowed him to study the longitudinal diffusion of decaying organisms within them. A great discovery from this work was that the trees have ways to dazzle the decomposition tissues, which called Decay Compartmentalization in Trees (CODIT. ) This has led to reassesssing arboricultural practices such as pruning techniques and cavity treatments, which have shown that many current practices then (such as tar coating cuts) have actually promoted decay or have been ineffective. The A-300 Pruning Standard AID reflects its recommendations. Shigo publications produced over 270 publications,[4] including many research documents, books, brochures, CDs and DVDs. Retired, he and his wife Marilyn published these as Shigo and Trees, Associates. He traveled around the world through presentations, workshops, seminars and demonstrations, sharing his passion for trees. Shigo and Trees, Associates business was transferred to their daughter in 2005.
