Assigning a fair monetary value to individual trees is an important skill for municipal and consulting arborists as well as anyone who is responsible for managing a property, park, or arboretum. This workshop focuses on the theory and practice of the appraisal of woody plants. James will review the various approaches to valuation that are currently available and how to determine which is the most suitable choice. The primary focus will be on the Cost Approach and the Trunk Formula Method for determining monetary value. The outdoor component of the workshop involves simulated appraisals on several trees in the Arboretum with hands-on instruction. An analysis of each problem will follow. The instructional material follows the 9th edition of the Guide for Plant Appraisal (International Society of Arboriculture) as prepared by the Council of Tree and Landscape Appraisers (CTLA) and reflects current understanding and practice in arboriculture. Come prepared to be outside. This course carries 6.5 CEUs for ISA certified arborists (S=2, P=2.5, M=2.5).
