Abstract

The volume and character of woody material on the ground in four old-growth Douglas-fir cutting units in the Cascade Range in Oregon were determined before and after harvesting by cable and yarding of unutilized material (YUM). Total volume of residue increased after logging in all units. Coarse residues were reduced by YUM yarding. Small changes in the defect condition of the timber can drastically affect the amount and character of the residues remaining on the site. Modifying bucking procedures can result in the removal of a considerable volume of usable residue.
