Sewall Forestry & Natural Resources Consulting LLC President Bret Vicary, Ph.D., MAI, LPF, received special mention in the Fall Association of Consulting Foresters Newsletter, p. 6, as follows:

"The new 10th Edition of the Guide for Plant Appraisal by the Council of Tree and Landscape Appraisers (CTLA) is now available! The 10th Edition is the most informative and comprehensive alignment of current knowledge of the approaches, processes, and methods of plant valuation. The book is available from the International Society of Arboriculture (ISA) at

This edition represents a systematic evolution of plant appraisal that integrates new research into a deeper understanding of the strengths and weaknesses of the available methods. Included in this edition are detailed discussions of newly streamlined core concepts and terminology, a review of the organization and context of appraisal reports, and an updated emphasis on appraiser awareness of the environmental and ecological benefits plants provide.

ACF offers special thanks to member Bret Vicary who represents the association on the CTLA and who devoted years of effort to this new edition."
