Only a small portion of the wood produced in natural stands is on merchantable trees, and in many especially dense stands only an occasional merchantable tree is grown. The unusable trees die or are knocked down at the time of logging to become a residue problem (fig. 1).. Results of the levels-of-growing-stock study reported in this paper indicate that fo

Only a small portion of the wood produced in natural stands is on merchantable trees, and in many especially dense stands only an occasional merchantable tree is grown. The unusable trees die or are knocked down at the time of logging to become a residue problem (fig. 1).. Results of the levels-of-growing-stock study reported in this paper indicate that foresters can capture most of the total wood production on usable-sized trees by controlling stand density. Furthermore, the low density that looked best for timber production up to the present stand age also withdrew less water from the soil. STUDY AREA The Twin Lakes levels-of-growing-stock study is located on the Deschutes National Forest near Twin Lakes and Wickiup Reservoir. It is about 10 miles west of the Pringle Falls Experimental Forest and about 45 miles southwest of Bend at an elevation of approximately 4, 300 feet. Topography of the study area is very gently sloping toward a bowl-shaped depression with one end open. There is good water Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Dahms, Walter G. cn; Pacific Northwest Forest and Range Experiment Station (Portland, Or. ).
