Book Description
"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.

Book Description
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.

Book Description
Nature's engineering of wood through genetics, wind, and weather creates a wide variability in wood as a material. Consequently, manufacture and users of wood products are frequently frustrated in dealing with the forest resource. Manufacturers sometimes argue that wood is difficult to consistently process into quality products because of the wide range of properties that exist in this raw material. Users of wood products can be equally frustrated with the performance variability found in finished products. Nondestructive evaluation (NDE) technologies have contributed significantly toward eliminating the cause of these frustrations. NDE technologies have been developed and are currently used in lumber and veneer grading programs that result in engineered materials that have consistent well-defined performance characteristics. This brief volume explores some of the processes that are used to manufacture wood, including green wood technology and provides a bit of history to wood production and its uses too.
