Download or read book Silvicultural Research and the Evolution of Forest Practices in the Douglas-fir Region written by and published by . This book was released on 2007 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the origin, design, establishment and measurement procedures and first results of a large long-term cooperative study comparing a number of widely different silvicultural regimes applied to young-growth Douglas-fir (Pseudotsuga menziesii) stands managed for multiple objectives. Regimes consist of (1) conventional clearcutting followed by intermediate thinning; (2) retention of reserve trees to create a two-aged stand; (3) small patch cuts dispersed within a thinned matrix, repeated at approximately 15-year intervals to create a mosaic of age classes; (4) group selection within a thinned matrix on an approximate 15-year cycle; (5) continued thinning on an extended rotation; and (6) an untreated control. Each of these regimes is on operationsize units (about 30 to 70 acres each). Output variables to be evaluated include conventional timber growth and yield statistics, harvest costs, sale layout and administration costs, aesthetic effects and public acceptance, soil disturbance, bird populations, and economic aspects. Descriptive statistics and some initial results are presented for the first replicate, established in 1997-98.

Book Synopsis Stepping Back to Look Forward by : Charles H. W. Foster
Download or read book Stepping Back to Look Forward written by Charles H. W. Foster and published by Harvard University Forest. This book was released on 1998 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely collection of essays - written by nine recognized forestry and environmental specialists - tells the story of the conservation, use, and changes in the Commonwealth's forests over time. The book traces the development of pre-settlement, colonial, and post-Revolutionary War forest practices, and concludes with recommendations as to how history might be used to inform and shape future policy. Underscored is the importance of private and local leadership, such as the unique Massachusetts town forest movement. Economic contributions and educational programs are detailed, as well as the ways Massachusetts' leadership has influenced national forestry. Written for the layperson, and reflecting the particular experience and style of each contributor, the history will appeal to a range of readers from local conservation activists to forestry professionals and policymakers.
Book Synopsis Physiology of Woody Plants by : Stephen G. Pallardy
Download or read book Physiology of Woody Plants written by Stephen G. Pallardy and published by Academic Press. This book was released on 2010-07-20 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Woody plants such as trees have a significant economic and climatic influence on global economies and ecologies. This completely revised classic book is an up-to-date synthesis of the intensive research devoted to woody plants published in the second edition, with additional important aspects from the authors' previous book, Growth Control in Woody Plants. Intended primarily as a reference for researchers, the interdisciplinary nature of the book makes it useful to a broad range of scientists and researchers from agroforesters, agronomists, and arborists to plant pathologists and soil scientists. This third edition provides crutial updates to many chapters, including: responses of plants to elevated CO2; the process and regulation of cambial growth; photoinhibition and photoprotection of photosynthesis; nitrogen metabolism and internal recycling, and more. Revised chapters focus on emerging discoveries of the patterns and processes of woody plant physiology. * The only book to provide recommendations for the use of specific management practices and experimental procedures and equipment *Updated coverage of nearly all topics of interest to woody plant physiologists * Extensive revisions of chapters relating to key processes in growth, photosynthesis, and water relations * More than 500 new references * Examples of molecular-level evidence incorporated in discussion of the role of expansion proteins in plant growth; mechanism of ATP production by coupling factor in photosynthesis; the role of cellulose synthase in cell wall construction; structure-function relationships for aquaporin proteins
