Plants have value. It can be difficult to assign this value based on intangible factors. However, assigning a value to a tree (valuation) is frequently what is required in legal settlements for damage or death of plants, resulting loss of property value, and many other reasons. The Council of Tree & Landscape Appraisers provide a system for valuation of trees by several different methods, depending on the circumstances. In addition to many years conducting timber appraisals, Richard has received training from the Inter. Society of Arboriculture to conduct valuation assessments on urban trees.
