Abstract
Did you know that about one fifth of every pine tree harvested remains underground and not visible to the naked eye? Why then couldn't land managers utilize this wood, thus getting the most out of any tree cut and keeping the number harvested to a minimum? Good idea, says Forest Service researcher Dr. Peter Koch, who has designed a machine to pluck the taproot from the ground-like a big carrot-while it is still attached to the tree trunk.
