Book excerpt: Excerpt from Lumber Recovery of Douglas-Fir From the Coast and Cascade Ranges of Oregon and Washington Volume recovery differed by log diameter, among mills, and by the units used to measure both logs and lumber, and may differ by whether the logs are measured as they come from the woods or after they have been bucked to mill lengths. Regres sion curves of recovery ratio, lumber recovery factor, or cubic recovery percent are plotted for both woods-length and mill-length logs. The cubic recovery percent for the combined mills reached about 76 percent of thalog volume for logs greater than 20 inches. Recovery ratio ranged from 225 to 130 percent across diameter.

This book was released on 2018-09-13 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Lumber Recovery From Old-Growth Coast Douglas-Fir The volume of commercial Coast Douglas-fir sawtimber is estimated to be in excess of 394 billion board feet. About 10 billion board feet of Coast Douglas fir is harvested annually. This is about 55 percent of the total softwood lumber production in the United States. There is an urgent need for better methods of appraising the quality of this important timber resource. Estimates of the recovery that can be obtained from Coast Douglas-fir sawtimber are needed by forest land managers, timber buyers, and timber processors for efficient utilization of the resource for lumber, veneer, pulp, or other products.

Lumber recovery percent increased as defect percent increased, indicating that recovery percent was more closely related to estimated defect than to diameter.

Book excerpt: Excerpt from Results of Shelterwood Harvesting of Douglas-Fir in the Cascades of Western Oregon U. S. Forest Service experience has shown that clearcutting Douglas-fir in the Pacific Northwest does not always result in successful regeneration, either natural or artificial. Where regeneration has failed, this has been due to such causes as temperature extremes and drought. Failures, primarily at higher elevations in the Oregon Cascades, led the Forest Service to try shelter wood harvesting, beginning in 1962, as a possible alternative to clearcutting. I surveyed these initial shelterwood stands in summer 1970 with two main objectives. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.

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 Lumber Manufacture in the Douglas Fir Region The low, intermediate, and high figure Of costs of operation, repairs, and supplies are meant to cover not the range for mills of any specific size but the general range for all classes, regardless Of size or type. SO far as pos sible, the effect of size or type of Operation has been mentioned with other factors bearing on such costs, but sufficient data was not available to bring out in each case the exact effect Of size of Operation on the particular cost item. The machinery and equipment prices are those in effect in 1916. The costs per thousand feet are in terms of the volume of finished product and not log scale or other temporary volumes. The drawings of machines and equipment are entirely for illustrative pur poses and must not be considered in any sense as an endorsement of the style or types shown.
