Notes and Observations: Worm-Hole-Free Lumber Salvaged from Borer-Damaged Pine Logs
A yield curve estimate was made for the volumes of worm-hole-free lumber expected from eastern white pine logs of different diameters that were damaged the preceding summer by insect pests of unseasoned logs. In comparison with the total volume of lumber expected in each diameter class (from International Log Scale), the estimated percentages of worm-hole-free lumber increased from zero in the six inch class, through 50 percent in the 14 inch class, to 68 percent in the 23 inch class, the largest diameter available.
