Which factor influences the grade of a log?

Which factor influences the grade of a log?

• A. Quality of the log, including defects
• B. Harvest season
• C. Soil type
• D. Tree age

Answer: (A)

Log grade is determined primarily by its quality, especially the presence and severity of defects. A log that is straight, sound, and free of knots, cracks, warp, rot, or other damage will be classified at a higher grade because it yields better value for high-quality lumber or veneer. Defects reduce grade because they limit usable size, strength, appearance, and end-use options, lowering the potential price and applications. Harvest season, soil type, and tree age can influence growth, moisture content, and the likelihood of defects, but they don’t define grade themselves; the grading system centers on the actual quality and defects of the log.
