Since the book’s release, the International Society of Arboriculture, as publisher, and in concert with the Council of Tree and Landscape Appraisers, has been cataloging important revisions, which are documented in the Corrigendum. Click here to download the Corrigendum PDF. We suggest you print it and keep it with your copy of the book for easy reference.
 
Reprints of this tenth edition will include these revisions incorporated directly into the text.
