Download or read book Juvenile Wood in Forest Trees written by Bruce J. Zobel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The trend in forestry is toward shorter rotations and more complete utiliza tion of trees. The reasons are: (1) financial pressures to obtain rapid returns on the forestry investment made possible by an earlier harvest; (2) enforced harvest of young plantations to maintain a continuing supply of cellulose for mills where wood shortages are experienced; (3) thinning young plantations, both because they were planted too densely initially and because thinning is done where long rotation quality trees are the forestry goal; (4) more intensive utilization is being done using tops and small diameter trees; and (5) there is interest in using young (juvenile) wood for special products because of its unique characteristics and the development of new technologies. The largest present-day source of conifer juvenile wood is from thinnings of plantations where millions of hectares of pine were planted too densely. Because of the better growth rate resulting from improved silviculture and good genetic stock, plantations will need to be thinned heavily. As a result of this trend, young wood makes up an increasingly larger proportion of the total conifer wood supply each year. Large amounts of juvenile wood from hard woods are also currently available, especially in the tropics and subtropics, because of the fast growth rate of the species used, which results in shorter rotations and ess~ntially all juvenile wood.

Download or read book International Review of Forestry Research written by John A. Romberger and published by Elsevier. This book was released on 2013-10-22 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Review of Forestry Research, Volume 2 is a collection of reviews and summaries of world literature concerning trees, forests, and forestry. This volume is divided into six chapters, and begins with a brief presentation of the historical developments of forest science and forestry research in East Asia. The succeeding chapters evaluate the influence of spacing on the growth and development of different coniferous tree species, as well as the influence of silvicultural practices on wood quality. These topics are followed by discussions on the various aspects of forest meteorology and the optimal conditions for vigorous root growth. The final chapter looks into the successions of organisms in discoloration and decay processes in living trees. This book will prove useful to forest scientists, research workers, teachers, advanced students, administrators, economists, and forest and land managers.

Download or read book Forest Mensuration written by John A. Kershaw, Jr. and published by John Wiley & Sons. This book was released on 2016-11-04 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest mensuration – the science of measurement applied to forest vegetation and forest products – holds value for basic ecology as well as sustainable forest management. As demands on the world’s forests have grown, scientists and professionals are increasingly called on to quantify forest composition, structure, and the goods and services forests provide. Grounded in geometry, sampling theory, and ecology as well as practical field experience, forest mensuration offers opportunities for creative problem solving and critical thinking. This fifth edition of the classic volume, Forest Mensuration, includes coverage of traditional and emerging topics, with attention to SI and Imperial units throughout. The book has been reorganised from the fourth edition to better integrate non-timber and ecological aspects of forest mensuration at the tree, stand, forest, and landscape scales throughout. The new edition includes new chapters that specifically address the integration of remotely sensed data in the forest inventory process, and inventory methods for dead and downed wood. One unifying theme, not only for traditional forestry but for the non-timber inventory and for remote sensing, is the use of covariates to make sampling more efficient and spatially explicit. This is introduced in the introductory chapter on statistics and the chapter on sampling designs has been restructured to highlight this approach and lay the foundation for further learning. New examples will be developed throughout the textbook with an emphasis on current issues and international practice. Students in applied forestry programs will find ample coverage of forest products and timber inventory, while expanded material on biodiversity, biomass and carbon inventory, downed dead wood, and the growing role of remote sensing in forest assessment will be valuable to a broader audience in applied ecology.

Available in PDF, EPUB and Kindle. Book excerpt: The new, revised edition of the standard volume on forest measurement The updated edition of this long-standing classic, Forest Mensuration, Fourth Edition, provides new, complete coverage of current measurement practices and technological applications that expand the role of forest mensuration to include monitoring forest resources. This integrated approach takes into account all the resources of a forest, including such nontimber vegetation parameters as regeneration, lesser vegetation, woody detritus, and carbon. Providing solid working knowledge of all concepts and methods, along with guidance for further study, featured material includes: * Applications of personal computers, global positioning, and GIS * Key concepts of tree-stand parameters and principles of measurement * Fundamental concepts of sampling methods * English and metric units Forest Mensuration, Fourth Edition, is a valuable resource for students in forestry and forestry-related studies.
