Book excerpt: Forest managers are beginning to take an interest in management of young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) in Western Oregon and Washington. Studies have established the relationship between growth and levels-of-growing-stock but few have established a link to wood quality and value. This study used data collected from a long term stocking study and established how log quality, product yield, and stand value were affected by repeated early thinnings across a wide range of stand densities. Methods developed by Briggs and Fight (1992) using the ORGANON and TREEVAL computer models to quantify Douglas-fir log quality, product yield and associated dollar value were used. Five thinning densities were considered on plots which are a part of the levels-of-growing-stock (LOGS) cooperative located west of Corvallis in Western Oregon. At stand age 30 all thinning densities consisted of low quality and value log grades. By stand age 50 log quality improved considerably for all treatments. Projections made to stand age 100 show additional improvements in log quality and dollar value. All thinning treatments had a greater proportion of volume in higher quality logs than the unthinned control. Total standing volume was reduced as thinning intensity increased. Gross stand value was found to be highly related to standing board foot volume. By stand age 100 the lightest thinned treatments had the greatest total value and volume. Product yield recovery was found to be fairly consistent between thinning treatments in the mix of lumber grades produced throughout the 80 year analysis period. This was attributed to little change in limb size between treatments and through time. Gross dollar value of lumber produced was found to be highly related to volume yield. The lightest thinned treatments had the greatest standing volume and value in lumber by stand age 100.

Available in PDF, EPUB and Kindle. Book excerpt: Public debate has stimulated interest in finding greater compatibility among forest management regimes. The debate has often portrayed management choices as tradeoffs between biophysical and socioeconomic components of ecosystems. Here we focus on specific management strategies and emphasize broad goals such as biodiversity, wood production and habitat conservation while maintaining other values from forestlands desired by the public. We examine the following proposition: Commodity production (timber, nontimber forest products) and the other forest values (biodiversity, fish and wildlife habitat) can be simultaneously produced from the same area in a socially acceptable manner. Based on recent research in the Pacific Northwest, we show there are alternatives for managing forest ecosystems that avoid the divisive arena of 'either-or' choices. Much of the work discussed in this book addresses two aspects of the compatibility issue. First, how are various forest management practices related to an array of associated goods and services? Second, how do different approaches to forest management affect relatively large and complex ecosystems?
