Guide for Plant Appraisal 9th Edition
The book is the ultimate reference for professional appraisers called in to determine the cost of the damage to landscape trees and shrubs wrought by winds, rain storms, ice and wet snow loads. It is the collective work of experts in arboriculture and landscaping who together have set guidelines on determining the worth of a wide range of trees in a multitude of settings.
The guide is recognized by the courts and insurance companies as a reliable arbiter in settling damage claims or assessing losses in property values. Without it, homeowners attempting to receive compensation for damage to trees could be entangled in endless debates based on nothing else but opinions.
Five green-industry associations collaborated in the making of the national guidelines. Each one endorses the publication by urging property owners to engage only those appraisers who rely on its procedures as their primary source in making their calculations. The groups are the International Society of Arboriculture, the American Association of Nurserymen, the Associated Landscape Contractors of America, the American Society of Consulting Arborists, and the Tree Care Industry Association.
According to officials of the International Society of Arboriculture, good landscaping can boost the market value of a property from 5% to as much as 20%. Trees are therefore tangible assets. Some homeowners have added comprehensive coverage riders to their home insurance policies to cover at least limited storm losses to shade and ornamental trees.
