Estimators And Characteristics Of Logging Residue In Montana Classic Reprint

Excerpt from Estimators and Characteristics of Logging Residue in Montana Ratios are presented for estimating volume and characteristics of logging residue in Montana. They relate cubic foot volume of residue to thousand board feet of timber harvested and to acres harvested. Tables show gross and net volume of residue, with and without bark, by diameter and length classes; by number of pieces per acre; by percent soundness; by product potential; and by degree of slope and distance to roads. Keywords: Residue estimation, resi due measurements, slash, volume estimation, slash utilization, residue management, Montana.

Excerpt from Logging Residues on Saw Log Operations, Idaho and Montana The net volume of logging residues represents underutilization by one standard or another. By Forest Survey's cubic-foot standards, residues include all unused net volume between a 1-foot stump and a 4-inch minimum top diameter inside bark By board foot standards, net residue volume consists of unused material in sawtimber trees from a 1 - foot stump to either the variable or the fixed top diameters. Mer chantable logs missed in skidding are included in saw timber residues. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Logging Residue in Southeast Alaska Detailed information on logging residues in southeast Alaska is provided as input to economic and technical assessments of its use for products or site amenities. Two types of information are presented. Ratios are presented that can be used to gener ate an estimate, based on volume or acres harvested, of the cubic-foot volume of residue for any particular area of southeast Alaska. Separate ratios are given for live and dead or cull material, and for net and gross volume. Tables display per-acre residue volume by various characteristics that might affect either use or disposition. These tables show net or gross volume, or both, by diameter and length classes, by origin, by percentage of soundness, by degree of slopes and distance to roads, and by number of pieces of residue per acre. Keywords: Southeast Alaska, logging residue, slash, residue estimation, fuel wood, residue management. A large volume of woody biomass has traditionally remained on site after logging in southeast Alaska. Interest is growing in this material for energy and conventional products, as well as for its environmental attributes. A great deal of information is needed on the volume and characteristics of residue to adequately address these options. Existing sources were out of date and did not provide the information needed to make site-specific assessments for southeast Alaska. This study provides the capability to estimate the volume and characteristics of logging residue throughout southeast Alaska. This study had two objectives. The first was to develop ratios for use in estimating the volume of logging residue for any area in southeast Alaska. These ratios relate the quantity of residue to timber harvest volume or harvested acres. Study results show, for example. An average net volume of logging residue (wood only) of 79 to 109 cubic feet per thousand board feet of harvest and an average gross volume ranging from 125 to 158 cubic feet per thousand board feet of harvest. The second objective was to provide data characterizing logging residue in ways that might affect its utilization for various products or its management for environmental considerations.

Excerpt from Ratios for Estimating Logging Residue in the Pacific Northwest Ratios are presented for estimating the volume of logging residue for any loca tion in Idaho, Washington, and Oregon. They show cubic-foot volume of logging residue per board feet of timber harvested and per acre harvested. Tables show gross and net volumes, with and without bark. The volumes of live and dead and cull residue at the time of harvest are also given. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book describes the new generation of discrete choice methods, focusing on the many advances that are made possible by simulation. Researchers use these statistical methods to examine the choices that consumers, households, firms, and other agents make. Each of the major models is covered: logit, generalized extreme value, or GEV (including nested and cross-nested logits), probit, and mixed logit, plus a variety of specifications that build on these basics. Simulation-assisted estimation procedures are investigated and compared, including maximum stimulated likelihood, method of simulated moments, and method of simulated scores. Procedures for drawing from densities are described, including variance reduction techniques such as anithetics and Halton draws. Recent advances in Bayesian procedures are explored, including the use of the Metropolis-Hastings algorithm and its variant Gibbs sampling. The second edition adds chapters on endogeneity and expectation-maximization (EM) algorithms. No other book incorporates all these fields, which have arisen in the past 25 years. The procedures are applicable in many fields, including energy, transportation, environmental studies, health, labor, and marketing.

Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

"Pinus radiata (radiata pine) is a versatile, fast-growing, medium-density softwood, suitable for a wide range of end-uses. Its silviculture is highly developed, and is built on a rm foundation of over a century of research, observation and practice. Radiata pine is often considered a model for growers of other plantation species. This book explores current knowledge of, and experience with radiata pine forest plantation management and examines its long-term sustainability. Radiata pine management needs to integrate the biological aspects of tree-growing, with socio-economics, management objectives, practical considerations and other constraints and opportunities. Although stands of radiata pine may appear to be simple, they are actually quite complex ecosystems because they contain large, long-lived trees that change dramatically over time and interact in changing ways with the environment and with other organisms. The focus of this book is on the principles and practices of growing radiata pine sustainably. It also looks ahead to emerging challenges facing radiata pine plantation management, such as the effects of climate change, new diseases and other threats, and meeting changing product needs and societal demands."--Page 4 of cover.
