What is the minimum DBH for veneer logs?

• A. 12 inches
• B. 15 inches
• C. 18 inches
• D. 20 inches

Answer: (C)

Veneer logs come from large-diameter trees because peeling thin sheets from a log is most economical when the log has enough usable wood along its length to offset waste and processing costs. Diameter at breast height (DBH) is a key measure of trunk size, and a threshold around 18 inches is used to ensure there’s sufficient veneer yield and acceptable quality. Logs smaller than that tend to produce little recoverable veneer, higher waste from taper and defects, and poorer economics for peeling. The other options are generally too small to reliably deliver economical veneer production, while 20 inches is larger than the common minimum, making 18 inches the typical standard used to identify veneer-eligible trees.
