  Citation × Citation Citation Abstract Copy Title: Logging planning and layout costs for thinning : experience from the Willamette Young Stand Project Author: Milota, Ginger, Stringham, Bennett, Oregon State University. Forest Research Laboratory, Kellogg, L. D. (Loren D.) 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 single-grip harvester and forwarder), tractor, and skyline. Data for the study came from two sources: activities completed by the Forest Service in preparing sales for bid, and the layout completed by the logging contractor after a contract was awarded. Planning and layout costs showed no consistent relationship to type of silvicultural treatment. Logging contractor layout costs showed a relationship to type of logging system: the mechanized system had the lowest layout cost, followed by the tractor systems, with the skyline systems having the highest costs.

  Citation × Citation Citation Abstract Copy Title: Regenerating coastal forests in Oregon : an annotated bibliography of selected ecological literature Author: Loucks, Donna M., Oregon State University. Forest Research Laboratory, Shainsky, Lauri J., Knowe, Steven A. (Steven Alan), 1954-, Pancheco, Alex A. This annotated bibliography was compiled to provide a comprehensive list of sources on the ecological factors that affect forest regeneration. Abstracts from 494 publications are indexed by author, species, and subject, and are arranged into 4 major sections. Topics include the effects of biotic factors, abiotic factors, and stand and site history on vegetation, effects of vegetation on aerial and soil resources, effects of vegetation on stand development, vegetation management, plant succession, and response of vegetation to silvicultural activities and disturbances. The citations are predominately for coastal Douglas-fir occurring west of the Cascade Range in Oregon and Washington; however, applicable citations for associated conifers, hardwoods, shrubs, and herbs and for Alaska, California, and British Columbia are also included. Citations on forest genetics, seeds, seedling physiology, and insects are not included in the bibliography.
