Creator:: Kellogg, L. D. (Loren D.), Spong, Ben, and Oregon State University. Forest Research Laboratory
Abstract:: Young Douglas-fir stands were commercially thinned to achieve vegetation- and wildlife-related objectives. Harvesting and forwarding production and costs were compared among three mechanized thinning treatments: light thin [(115 residual trees per acre (tpa)], light thin with 0.5-ac openings (92 residual tpa), and heavy thin (53 residual tpa). The sites were...

Creator:: Beuter, John H., Handy, Jeffrey King, and Oregon State University. Forest Research Laboratory
Abstract:: Some of the world's most productive timberland lies on the slopes of the coastal range in Oregon and Washington. More than one-half of the commercial forest land in that area is estimated as high site quality for Douglas-fir, with a site index of 140 or better. But much of this...

Creator:: Tappeiner, J. C. (John C.), Bell, John F., Brodie, J. Douglas (John Douglas), 1938-, and Oregon State University. Forest Research Laboratory
Abstract:: A 20-year-old Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] stand in the Oregon Coast Range was thinned from about 1,700 to about 350 trees/ac. Subsequent thinnings, under eight different regimes, occurred at ages 23, 27, 30, and 32. Average net periodic cubic-volume growth was strongly influenced by thinning regime, varying from about...

Creator:: Hann, David W. and Oregon State University. Forest Research Laboratory
Abstract:: Summaries from 49 published articles on site-index and dominant-height growth curves and equations are presented for 20 tree species or species groups found in California, Oregon, Washington, British Columbia, southeastern Alaska, Idaho, and western Montana. The summaries are organized by species. Each summary describes the modeling approach, type of curves/equations,...

Creator:: Hann, David W., Riitters, K. H. (Kurt H.), and Oregon State University. Forest Research Laboratory
Abstract:: Tables are presented that summarize 108 published articles on forest growth and yield in the Pacific Northwest. Each table describes the form of the information presented, the species to which the information is applicable, the data sources used to develop the information, the data needed to predict growth and yield,...

Creator:: Tesch, S. D., Mann, John William, and Oregon State University. Forest Research Laboratory
Abstract:: Clearcut and shelterwood reproduction methods are both important, silviculturally viable reforestation tools for southwest Oregon. The ecology of local forests lends itself to the successful application of either method, in most cases; thus, choice of method is typically based on land management objectives, which integrate social and resource values, economics,...

Creator:: Vomocil, Marc G., Tedder, Philip L., and Oregon State University. Forest Research Laboratory
Abstract:: Comparisons were made to determine how the uncertainty of initial inventories and projected yields affect harvest schedules for Douglas-fir. Results indicate that short-run harvests are most affected by errors in initial inventory, with the effect being less than the size of the error. Long-run harvests are most affected by yield...
