Modern Arboriculture is about new and better ways to help trees stay healthy, safe and attractive. Learn about: tree systems; how they grow, defend themselves and how and why they eventually die. How to use your mind as well as your muscles for affecting tree management. How many old treatments have hurt the tree system, and adjustments to old practices that must be made now.

• DUBBED THE "FATHER OF MODERN ARBORICULTURE", Dr. Alex Shigo has spent most of his adult life studying, lecturing, dissecting and writing about trees. "A tree is much more than a chunk of dead wood," exclaims Shigo. "Trees are alive; they live all year 'round, not just for a short time in the summer." They work during the winter, too. Many people spend time on what goes wrong with a tree; I wanted to study what goes right."
