Abstract
One question frequently asked by foresters in the Douglas-fir region is: "How much land is taken out of forest production by logging roads and landings?" The final answer is not known, but a rough estimate recently prepared for a sizable portion of the H. J. Andrews Experimental Forest may be useful as a tentative figure. The experimental area is located about 50 miles east of Eugene, Oregon on the Willamette National Forest and is fairly typical of the old-growth Doughs-fir forests that are found on steep watersheds in the Oregon Cascades.
