Works of Dr. Alex Shigo

05/01/12

Shigo and Trees, Associates was begun in 1985 by Alex and Marilyn Shigo at their home in New Hampshire. Alex had retired after more than 25 years as Chief Scientist in the US Forest Service, and had many ideas about trees and their care to share. His first book was A New Tree Biology, a totally new vision of trees and their physiology based on his many years of tree dissections, published in 1986. For twenty years of “retirement” he traveled throughout the USA and the world giving demonstrations, making presentations, organizing workshops and educational seminars, talking with individuals, and sharing his passion about trees.
