Download or read book Sampling Plantation Eucalypts for Wood and Fibre Properties written by GM Downes and published by CSIRO PUBLISHING. This book was released on 1997-01-01 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was written to help the forest industry assess wood quality by using non-destructive samples taken from specific points within a tree. It is the first compilation of research data on sampling of eucalypts, describing new methods and tools for rapid and cost-effective analysis. The book provides information needed to design a sampling program, obtain and process wood samples, and shows how to relate the data to an average tree value.

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 Forest Mensuration written by Anthonie van Laar and published by Springer Science & Business Media. This book was released on 2007-07-20 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Van Laar and Akça’s popular text book, Forest Mensuration, was first published in 1997. Like that first edition, this modern update is based on extensive research, teaching and practical experience in both Europe, and the tropics and subtropics. However, it has also been extensively revised, and now includes chapters on remote sensing and the application of aerial photographs and satellite imagery. The book assumes no advanced knowledge of statistical methods, and combines practical techniques with important historical and disciplinary context. The result is a strong balance between a handbook and a valuable reference.

Download or read book Wood Variation written by Bruce J. Zobel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is the usual end product of a forestry operation. Because of its importance, numerous studies have been made relative to wood prop erties, the causes of wood variation, and how best to develop wood for desired products. There is voluminous literature related to these subjects, but it is neither well known nor appreciated by foresters because the publications are often not available or are not well understood by the forester or by those who use the wood. Frequently, the literature is confusing and contradictory, making it difficult for the nonspecialist to use what information is available. In order to produce and use wood efficiently, the variation pat terns within trees, among trees within species, and among species must be understood. This also requires some knowledge of the causes of variation and the effects of different wood properties upon utiliza tion. The information about variation patterns, their causes, and con trol and effect upon the product must be known by the tree grower, the tree breeder, and the tree harvester as well as by those who ultimately convert wood into a final, salable product.

Available in PDF, EPUB and Kindle. Book excerpt: The ninth volume of Water-in-Plants Bibi iography includes papers in al I fields of plant water relations research which appeared during the year 1983. - from theoreti cal considerations about the state of water in cel 15 and its membrane transport to drought resistance of plants or physiological significance of irrigation. In addition to papers devoted entirely to plant water relations, papers on other topics are in cluded if they contain data on plant hydration level, water vapour efflux, rate of water uptake or water transport, etc., or if they contain valuable methodological in formation (measurement of selected microclimatic factors, soi I moisture etc. l. We have tried to cover ful Iy the relevant papers which have been publ ished in important scientific periodicals and books. Articles appeared in local journals, mimeographed booklets, abstracts of thesis and of symposia contributions, etc., were chosen mostly from reprints received directly from authors. The courtesy of those is highly appreciated. The manuscript is usual Iy prepared in May and June of the year fol lowing the year which it covers. Unfortunately some reprints come later and thus the respective references appear in the fol lowing volume, with one year delay. To maximize the value of the bibi iography the references are arranged alphabetic al Iy according to the authors' names, and each volume is provided with three indexes.
