Decay and other defects in trees constitute a perplexing problem in the determination of merchantable timber volume. Inaccuracy in net volume estimation is perhaps the greatest disadvantage to the practice of selling stumpage. As a contribution toward efficient cruising and net volume determination, this article presents a method of estimating cull volume in the standing tree. It describes the important defect indicators for lodgepole pine, Engelmann spruce, and alpine fir in the Central Rocky Mountain region; it outlines procedures to be followed in the estimation of defect; and concludes by showing the accuracy attained in actual field trials.
