Download or read book Lumber Recovery from Incense cedar in Central California written by W. Y. Pong and published by . This book was released on 1988 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sample of 130 incense-cedar (Libocedrus decurrens Torr.) trees was selected from the EIdorado National Forest in California. The trees were felled and bucked into 403 woods-length logs and processed through a sawmill cutting Shop and Common grades of lumber. Recovery estimates are shown for woods-length logs based on Scribner board-foot scale and cubic-foot scale. Analysis showed that board-foot recovery ranged from 169 percent for 6-inch logs to 103 percent for 34-inch logs. Cubic-volume recovery of rough green lumber increased from 50 percent to 62 percent for the same range of diameters. Yields of higher quality lumber (Shops and Moulding) increased as log diameter increased. Percentage of Scribner scaled defect was found to be correlated with several measures of product recovery.

Keywords: Lumber recovery, lumber value, incense-cedar, log scale, California. This report presents lumber-recovery data for 130 incense-cedar trees selected from the Sierra Nevada of central California. Over 400 woods-length logs were processed through a sawmill cutting Shop and Common grades of lumber. Diameter of the study logs ranged from 6 to 34 inches. The average defect was from-4 to 17 percent Scribner and 3 to 10 percent cubic scale. Lumber recovery is presented on the basis of both board feet and cubic feet. Several measures of product recovery were correlated with scaling diameter. Regres sion models were developed for the following variables.

Book excerpt: Excerpt from Lumber Recovery From Ponderosa Pine in Northern California Lumber recovery information from 942 logs from old and young-growth pon derosa pine (pinus ponderosa Dougl. Ex Laws.) trees in northern California is presented. More than 58 percent of the lumber volume was found in Shop, Moulding, and Select grades.

Volume recovery varied by scaling diameter but not by log grade. Value recovery and percent vol ume by lumber grade did vary by log grade and diameter, but no difference was found between the grade 1 and the grade 2 logs.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Incense Cedar The yield Of various grades of lumber from an incense cedar tree depends very largely, Of course, on the amount Of dry-rot. This varies SO widely, however, in different trees in one locality as well as in trees in different localities that data based on the yields Of pecky trees would have very little general application. The yields indicated in Table 4 are based therefore on sound trees and are fairly typical Of the yield where there is no dry-rot.

This book was released on 2018-09-13 with total page 56 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.

This book was released on 2018-03-17 with total page 44 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book John Muir s Last Journey written by John Muir and published by Island Press. This book was released on 2004-01-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "I am now writing up some notes, but when they will be ready for publication I do not know... It will be a long time before anything is arranged in book form." These words of John Muir, written in June 1912 to a friend, proved prophetic. The journals and notes to which the great naturalist and environmental figure was referring have languished, unpublished and virtually untouched, for nearly a century. Until now. Here edited and published for the first time, John Muir's travel journals from 1911-12, along with his associated correspondence, finally allow us to read in his own words the remarkable story of John Muir's last great journey. Leaving from Brooklyn, New York, in August 1911, John Muir, at the age of seventy-three and traveling alone, embarked on an eight-month, 40,000-mile voyage to South America and Africa. The 1911-12 journals and correspondence reproduced in this volume allow us to travel with him up the great Amazon, into the jungles of southern Brazil, to snowline in the Andes, through southern and central Africa to the headwaters of the Nile, and across six oceans and seas in order to reach the rare forests he had so long wished to study. Although this epic journey has received almost no attention from the many commentators on Muir's work, Muir himself considered it among the most important of his life and the fulfillment of a decades-long dream. John Muir's Last Journey provides a rare glimpse of a Muir whose interests as a naturalist, traveler, and conservationist extended well beyond the mountains of California. It also helps us to see John Muir as a different kind of hero, one whose endurance and intellectual curiosity carried him into far fields of adventure even as he aged, and as a private person and family man with genuine affections, ambitions, and fears, not just an iconic representative of American wilderness. With an introduction that sets Muir's trip in the context of his life and work, along with chapter introductions and a wealth of explanatory notes, the book adds important dimensions to our appreciation of one of America's greatest environmentalists. John Muir's Last Journey is a must reading for students and scholars of environmental history, American literature, natural history, and related fields, as well as for naturalists and armchair travelers everywhere.
