The four major factors involved in properly assessing the value of a plant are size, species, condition and location. A thorough understanding of each is imperative.

First, check out our measuring guidelines for assistance in learning how to accurately measure the circumference at diameter breast height (the tree’s circumference at a height of 4.5 feet above ground level that is used for standard calculations). Then, you can make a simple estimation of benefits street trees provide by using an appraisal calculator. These calculators use the species, circumference or diameter, health and location to determine the current environmental and economic benefits your tree is providing, as well as the projected benefits your tree will provide over a set number of years.

You should also document your “investment” to help establish its worth. Taking pictures of trees and plants while they are healthy will make insurance processing simpler by having “before and after” documentation. If your trees have been damaged, contact a tree care professional and landscaping appraiser to assess the damage and determine the financial loss. Also, request a cost estimate to replace a tree of the same size, repair the tree or have the stump and roots removed.
