The effects of thinning on stand and tree growth in a young, high site Douglas-fir stand in western Oregon

Creator:: Marshall, David D.
Abstract:: The Levels-of-Growing-Stock Studies in Douglas-fir is a regional cooperative to investigate the effects of levels of growing stock on young stand growth. The Hoskins installation, in western Oregon, was established in a dense, high site natural stand at total age 20 years. The initial thinning resulted in an immediate 131...

Young stand thinning in Western Oregon : cost comparison of harvesting alternatives and comparison of time study techniques

Creator:: Hossain, Mohammad Mozaffar
Abstract:: Harvesting costs were determined for commercial thinning of young stands to achieve vegetation and wildlife objectives. This included replicated comparisons of thinning treatments. Treatments were defined based on residual tree stocking after thinning. Study procedures were developed and evaluated to improve statistical relevance. Multiple linear regression models were used to...

Response of young Douglas-fir to 16 years of intensive thinning

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...

Vegetation response following thinning in young Douglas-fir forests of western Oregon : can thinning accelerate development of late-successional structure and composition?

Creator:: Beggs, Liane R.
Abstract:: Across western Oregon, Washington, and British Columbia, forest management practices over the past century reduced the amount of late-successional forest while simultaneously increasing the amount of young (less than 80 years old), managed Douglas-fir (Pseudotsuga menziesii) dominated forests. Recently, concerns over loss of late-successional habitat pushed management objectives on public...

Logging planning and layout costs for thinning : experience from the Willamette Young Stand Project

Creator:: Kellogg, L. D. (Loren D.), Milota, Ginger, Stringham, Bennett, and Oregon State University. Forest Research Laboratory
Abstract:: Logging planning and layout costs were examined for commercial thinning of 40- to 50-yr-old stands of Douglas-fir on the Willamette National Forest in the Cascade Mountains of Oregon. The study consisted of four replications of three silvicultural treatments. Thinning involved three types of logging systems: mechanized cut-to-length (a combination of...
