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.
