Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Growth Studies in Forest Trees: I. Pinus Rigida Mill; II. Pinus Strobus L Little stress was put on the study of secondary root thickening in the present investigation. Only one cutting was taken, on April 27, 1910, for purposes of comparison, so that no reliable deductions can be made. At this time cambial activity was not manifest, although it must have been in process throughout the aerial portion with the possible exception of the apical shoot. T. Hartig (8) claimed that cambial awakening in the roots is much later than in the aerial portions. He gave midsummer as the time of first inception and said it continued far into October. Whether the same applies to Pinus rigida further investigation only can decide. Suffice it to say, however, that the growth in thickness of roots must not be confused with growth in length. The latter is manifest often as early as March and continues throughout the season. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: The present studies were undertaken with a twofold purpose, namely, to clear up disputed points regarding annual ring formation in trees and to formulate laws of tree growth. Investigations were carried on upon various forest trees with this idea in view. The results of those on Pinus rigida are embodied in this paper.

This book was released on 2009-03-05 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses advanced statistical methods that can be used to analyse ecological data. Most environmental collected data are measured repeatedly over time, or space and this requires the use of GLMM or GAMM methods. The book starts by revising regression, additive modelling, GAM and GLM, and then discusses dealing with spatial or temporal dependencies and nested data.

Download or read book Old Growth Forests written by Christian Wirth and published by Springer Science & Business Media. This book was released on 2009-07-07 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many terms often used to describe old-growth forests imply that these forests are less vigorous, less productive and less stable than younger forests. But research in the last two decades has yielded results that challenge the view of old-growth forests being in decline. Given the importance of forests in battling climate change and the fact that old-growth forests are shrinking at a rate of 0.5% per year, these new results have come not a moment too soon. This book is the first ever to focus on the ecosystem functioning of old-growth forests. It is an exhaustive compendium of information that contains original work conducted by the authors. In addition, it is truly global in scope as it studies boreal forests in Canada, temperate old-growth forests in Europe and the Americas, and global tropical forests. Written in part to affect future policy, this eminently readable book is as useful for the scientist and student as it is for the politician and politically-interested layman.
Download or read book Modeling Forest Trees and Stands written by Harold E. Burkhart and published by Springer Science & Business Media. This book was released on 2012-04-27 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing upon a wealth of past research and results, this book provides a comprehensive summary of state-of-the-art methods for empirical modeling of forest trees and stands. It opens by describing methods for quantifying individual trees, progresses to a thorough coverage of whole-stand, size-class and individual-tree approaches for modeling forest stand dynamics, growth and yield, moves on to methods for incorporating response to silvicultural treatments and wood quality characteristics in forest growth and yield models, and concludes with a discussion on evaluating and implementing growth and yield models. Ideal for use in graduate-level forestry courses, this book also provides ready access to a plethora of reference material for researchers working in growth and yield modeling.

Download or read book Growth Trends in European Forests written by Heinrich Spiecker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European Forest Institute (EFI) has five Research and Development priority ar eas: forest sustainability, forestry and possible climate change, structural changes in markets for forest products and services, policy analysis, and forest sector informa tion services and research methodology. In the area of forest sustainability our most important activity has been the project "Growth trends of European forests", the re sults of which are presented in this book. The project was started in August 1993 under the leadership of Prof. Dr. Heinrich Spiecker from the University of Freiburg, Germany, and it is one of the first EFI's research projects after its establishment in 1993. The main purpose of the project was to analyse whether site productivity has changed in European forests during the last decades. While several forest growth studies have been published at local, re gional and national levels, this project has aimed at stimulating a joint effort in iden tifying and quantifying possible growth trends and their spatial and temporal extent at the European level. Debate on forest decline and possible climate change, as well as considerations re lated to the long term supply of wood underline the importance of this project, both from environmental and industrial points of view. Knowledge on possible changes in growth trends is vital for the sustainable management of forest ecosystems.

Available in PDF, EPUB and Kindle. Book excerpt: The Principles of Forest Yield Study: Studies in the Organic Production, Structure, Increment and Yield of Forest Stands reviews the progress that has been made in the field of forest yield studies, especially those concerning the organic production, structure, increment, and yield of forest stands. Topics covered include woody growth as part of the total produce of plant societies; growth and form of forest trees; constitution and development of stands; and forest stand structure, increment, and yield in relation to silvicultural treatment. This book is divided into five sections and begins with an overview of the history of forest yield studies, as well as the place of forest yield theory in forest science. Research objectives and methods employed in forest yield studies are outlined. The discussion then turns to the interactions between soil, climate and plant production; the social structure of tree crops; growth performance of tree crops in relation to site; and disturbances in the normal trend of increment. The use of fertilizers for amelioration and treatment of forest soils are discussed from the standpoint of yield studies. This monograph will be a useful resource for practitioners in forestry, the natural sciences, plant physiology, soil science, and meteorology.
