This book was released on 1996 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Density manipulation is one of the most powerful tools available to silviculturists to achieve a broad range of silvicultural objectives. One of the most effective methods of planning density management in even-aged stands is through the use of stand density management diagrams. These diagrams graphically depict the temporal relationships between stand density, top height, quadratic mean diameter and mean tree volume. They allow the user to develop and project crop plans through time, to determine the optimum timing of thinnings, to determine the operational feasibility of thinnings, and to contrast potential outcomes from a number of stand management regimes. The stand density management diagrams for lodgepole pine, white spruce and interior Douglas-fir in this report were derived from managed stand yield tables produced by TASS, an individual tree, distance-dependent growth model. The report describes their use in planning thinning regimes and making preliminary yield estimations.

Available in PDF, EPUB and Kindle. Book excerpt: We review 12 large-scale silviculture experiments (LSSEs) in western Washington and Oregon with which the Pacific Northwest Research Station of the USDA Forest Service is substantially involved. We compiled and arrayed information about the LSSEs as a series of matrices in a relational database, which is included on the compact disc published with this report and available online at http://www.fs.fed.us/pnw/research/lsse. The LSSEs are both spatially and temporally large scale, with experimental treatment units between 5 and 100 acres and proposed study durations of 20 to 200 years. A defining characteristic of the LSSEs is that a broad range of response variables are measured to characterize the response of forest ecosystems to experimental treatments. We discuss the general value and limitations of the LSSEs and highlight some possible roles that can be played by the LSSEs in addressing management issues emerging at the beginning of the 21st century.
