Canyon BC, the name of Harris' book is Arboriculture, Integrated Management of Landscape Trees, Shrubs and Vines.
Clearance: Are you purposely trying to start another argument? Of course, that's not all there is. I was simply answering a specific question. The test is composed of not only identification, but biology, soil and water management, nutrition and fertilization, selection, installation and establishment, pruning, support and protection systems, diagnosis of various disorders and their management, general plant health care, assessment and risk management, trees vs construction, and safety and ....

And, again, this is considered a first step in establishing the basic understanding to becoming an arborist.
