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...

Abstract:: Growth was assessed for Douglasfir reproduction which had established naturally beneath three intensities of overstory thinning in a 65-year-old stand of Douglas-fir on the east side of the Oregon Coast Range. The age of advanced reproduction ranged from 4 to 15 years. Understory environments were described in terms of sunlight,...

Abstract:: Our diagram is intended to provide general guidance in density management of red alder. The management zone defines a reasonable compromise between individual-tree and stand growth and mortality. Factors considered in its formation include desired tree size at harvest, growth rate, and yield per acre. Social and legal constraints, as...

Abstract:: The goal of this study is to analyze how the ISC Conservation Strategy may influence Oregon's timber availability and economy in the context of overall changes in public land management. Two themes are important: first, how the state's future will differ from today and second, how the state's future will...

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...
