 Tree Appraisal - Tree Valuation Services

Trees provide many benefits and value to property owners in functional, aesthetic, social, environmental and even economic ways. Value may be defined as the present worth of future benefits. Many of these benefits can be quantified by a dollar figure, and it is the responsibility of an appraiser to assign monetary value. Appraising trees and living landscape components can be challenging, and requires training, expertise and experience.

The purpose of an appraisal is defined by the clients’ needs. These needs may include tort claims, insurance claims, tax deductions, real estate assessment and proactive planning. An appraisal estimates the defined value of personal property, including plants. The tree appraisal process is used to develop a supported estimate of current value. Unfortunately, most appraisals are done after trees have been removed or damaged. This situation requires additional investigation and might include determining pre-casualty value or sampling on a local basis.

The best time to conduct an appraisal is prior to any incident or damage. This is rarely done, however. If available, previous site records, tree assessments, site reviews, images and even a witness can help determine the tree’s pre-damage condition. With all the facts gathered, it is the duty of the appraiser to determine the appropriate method and provide an unbiased valuation.
