"The "Evaluating Tree Defects" field guide is an excellent resource for seeing the different types of tree defects, guidelines for evaluating those defects, and guidelines for evaluating tree decay. The field guide is often used by Arborist's to show to their customers while evaluating their trees. The field guide is 34 pages with 58 color photographs and 43 illustrations. The field guide explains how to evaluate the major categories of tree defects with eighteen easy to use field guidelines. There are several examples of each type of tree defect. Additionally, there are sections on the common defects of each species, resistance to decay by species, basic tree mechanics, terminology, and safety issues for arborists."--Pub. desc.
Excerpt from How to Recognize Hazardous Defects in Trees Trees add to our enjoyment of outdoor experiences whether in forests, parks, or urban landscapes. Too often, we are unaware of the risks associated with defective trees, which can cause personal injury and property damage. Interest in hazard tree management has increased in recent years due to safety and liability concerns resulting from preventable accidents. Recognizing hazardous trees and taking proper corrective actions can protect property and save lives. A hazard tree is a tree with structural defects likely to cause failure of all or part of the tree, which could strike a target. A target can be a vehicle, building, or a place where people gather such as a park bench, picnic table, street, or backyard. This brochure was created to help home owners and land managers in recognizing hazardous defects in trees and to suggest possible corrective actions. We recommend that corrective actions be undertaken by professional arborists. Because of the natural variability of trees, the severity of their defects, and the different sites upon which they grow, evaluating trees for hazardous defects can be a complex process. This publication presents guidelines, not absolute rules for recognizing and correcting hazardous defects. When in doubt, consult an arborist.

The timber quality inventory described recognizes and measures the basic stem characteristics and defect features that influence quantity and quality for most primary products. Stem features measured on sample trees include form defects, scar defects, and knot or limb characteristics. Timber inventory data obtained are used in conjunction with standard methods of estimating volume, scaling, and grading to estimate: (1) Gross volume suitable for a primary product; (2) Probable volume reduction due to visual scaling defects, and remaining net volume suited to the product; (3) Quality of the timber in terms of existing grading or quality classification systems.
