Book excerpt: Excerpt from Initial Thinning Effects in 70-to 150-Year-Old Douglas-Fir-Western Oregon and Washington The present inventory of post-rotation-aged Douglas-fir is so large that immediate harvest cutting is not a practical alternative for all such stands for all owners. Table 1 lists the volume and acreage of Douglas-fir stands in western Oregon and Washington in 1968 by 20 and 30-year age classes. At the average annual rate of cutting million board.

Book excerpt: Excerpt from Laminated Root Rot of Douglas-Fir in Western Oregon and Washington It is important primarily as a killer. Young infected trees seldom survive long enough for reduction of growth rate or extension of decay into the butt log to be of much consequence. In old-growth stands, where killing is slower, infection is less common, and decay usually extends only a few feet into butt logs and involves mostly the low-quality core. This paper summarizes results obtained during the past 20 years from research still in progress. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Potential Production in Thinned Douglas-Fir Plantations Therefore, production tables now available for mountainous areas of northern Italy and southern France are of particular interest. There, the lati tudes and climates (mean annual temperature 48° to 50° F. Rainfall 30 to 80 inches, and two dry summer months) correspond quite closely to those of Washington and Oregon. Estimates of potential yields on a high site are available from New Zealand (duff 1956; Spurr As will be seen later, it is difficult to distinguish pos sible effects on yield of differences in climate and soil from differences in thinning schedules and other causes.

Book Synopsis Response of Young Douglas-fir to 16 Years of Intensive Thinning by : John C. Tappeiner
Download or read book Response of Young Douglas-fir to 16 Years of Intensive Thinning written by John C. Tappeiner and published by . This book was released on 1982 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 220 ft /ac/yr (heavy thinning age 30) to over 550 ft /ac/yr (controls age 23). The results indicate that young Douglas-fir on productive sites (site index 160 to 170 ft at 100 years) are extremely adaptable and will respond to frequent thinnings of various intensities. Three representative treatments (after thinning at age 32) and the controls were projected and optimized with dynamic programming for two financial analyses. Adjusting rotation or commercial thinning can compensate for lack of early stand management or heavy early thinning.

Book excerpt: Excerpt from Natural Regeneration of Douglas-Fir and Associated Species Using Modified Clear-Cutting Systems in the Oregon Cascades The staggered-setting clear cut had only 407 Douglas-fir seedlings per acre and 28 percent of the plots stocked with any Species. Poor stocking is typical of many large clear cuts in this general area. For example, twelve 3 to 5-year-old clear cuts on the experimental forest surveyed in 1956 had an average of only 301 (range 81 to 525) Douglas-fir seed lings per acre. Total plots stocked with any Species averaged 28 (range 11 to 48) percent and plots stocked with Douglas-fir averaged only 24 (range 9 to 36) percent, even though both 1 and 2-year-old seedlings were included in the tally.
