Abstract:
A method of preparing a tree for standing-stem harvesting directly from the stump, comprisinga) topping the tree; b) cutting through the trunk of the tree near ground level to make a pair of generally horizontal saw cuts into the trunk, the deeper of which cuts is more than about half the diameter of the trunk at the point of cutting; the cuts terminating along cut edges generally parallel to one another and separated from one another by holding wood; and c) driving support wedges or the equivalent into both said cuts to stabilize the trunks; whereby the wedges and the holding wood maintain the trunk stable and upright until it is harvested, but the holding wood is readily frangible in response to a generally horizontal pivoting force applied to the trunk near the top thereof in a direction generally perpendicular to the cut edges, thereby to permit the trunk to be broken away from the stump for removal.
