Book excerpt: Maintaining or increasing stand productivity is the concern of forest land managers worldwide. Consequently, there is increasing interest in understanding the impact of environmental stress on productivity and the development of management strategies that ameliorate or reduce the deleterious effects. Invited scientists gathered in Fort Collins, Colorado on July 30, 1985, to present the current state of knowledge regarding the impact of environmental stress on forest stand productivity. Particular attention was given to elucidating the mode of action by which individual stress elements reduce productivity. Environmental factors and the levels that constitute stressed (suboptimal) conditions in forest stands were identified, and the effects of stress intensity and duration on key stand parameters, including photosynthesis, respiration, assimilate partitioning, senescence and mortality, were emphasized. The role of genetics and silvicultural treatments in lessening the stress impact on stand productivity was presented, particularly in regards to alternative methods for environmental stress management. Modeling of stand dynamics in response to environmental stress was explored as an effective research and management tool. VIII Improved forest management practices will develop as we improve our understanding of the nature of important environmental stresses and as we comprehend their impact on tree and stand performance, manifested through physiological processes and genetic potential. This book is dedicated to such an understanding and comprehension.

Download or read book Physiological Ecology of Forest Production written by J. J. Landsberg and published by Academic Press. This book was released on 2010-11-26 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Process-based models open the way to useful predictions of the future growth rate of forests and provide a means of assessing the probable effects of variations in climate and management on forest productivity. As such they have the potential to overcome the limitations of conventional forest growth and yield models, which are based on mensuration data and assume that climate and atmospheric CO2 concentrations will be the same in the future as they are now. This book discusses the basic physiological processes that determine the growth of plants, the way they are affected by environmental factors and how we can improve processes that are well-understood such as growth from leaf to stand level and productivity. A theme that runs through the book is integration to show a clear relationship between photosynthesis, respiration, plant nutrient requirements, transpiration, water relations and other factors affecting plant growth that are often looked at separately. This integrated approach will provide the most comprehensive source for process-based modelling, which is valuable to ecologists, plant physiologists, forest planners and environmental scientists. Includes explanations of inherently mathematical models, aided by the use of graphs and diagrams illustrating causal interactions and by examples implemented as Excel spreadsheets Uses a process-based model as a framework for explaining the mechanisms underlying plant growth Integrated approach provides a clear and relatively simple treatment
Download or read book The Use of Remote Sensing in the Modeling of Forest Productivity written by H.L. Gholz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests comprise the greatest storage of carbon on land, provide fuel for millions, are the habitat for most terrestrial biodiversity, and are critical to the economies of many countries. Yet changes in the extent and dynamics of forests are inherently difficult to detect and quantify. Remote sensing technologies may facilitate the measurement of some key forest properties which, when combined with other information contained in various computer models, may allow for the quantification of critical forest functions. This book explores how remote sensing and computer modeling can be combined to estimate changes in the carbon storage, or productivity, of forests - from the level of the leaf to the level of the globe. Land managers, researchers, policy makers and students will all find stimulating discussions among an international set of experts at the cutting edge of the interface between science, technology and management.

This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Energy Agency Bioenergy Agreement was initiated as the Forestry Energy Agreement in 1978. It was expanded in 1986 to form the Bioenergy Agreement. Since that time the Agreement has thrived with some fifteen countries (Austria, Belgium, Canada, Denmark, Finland, Italy, Japan, Netherlands, New Zealand, Norway, Sweden, Switzerland, United Kingdom, United States and the CEC) currently being signatories. The objective of the Agreement is to establish increased programme and project cooperation between the participants in the field of bioenergy. The environmental consequences of intensive forest harvesting have been the subject of intense interest for the Agreement from its initiation. This interest was formulated as a Cooperative Project under the Forestry Energy Agreement in 1984. It developed further under each of the subsequent three-year Tasks of the Bioenergy Agreement (Task III, Activity 3 "Nutritional consequences of intensive forest harvesting on site productivity", Task VI, Activity 6 "Environmental impacts of harvesting" and more recently Task IX, Activity 4 "Environmental impacts of intensive harvesting". The work has been supported by five main countries from within the Bioenergy Agreement: Canada, New Zealand, Sweden, UK, and USA. The continued work has resulted in a significant network of scientists work ing together towards a common objective - that of generating a better under standing of the processes involved in nutrient cycling and the development of management regimes which will maintain or enhance long term site productivity.

Available in PDF, EPUB and Kindle. Book excerpt: Lord Rutherford has said that all science is either physics or stamp collecting. On that basis the study of forest biomass must be classified with stamp collecting and other such pleasurable pursuits. Japanese scientists have led the world, not only in collecting basic data, but in their attempts to systematise our knowledge of forest biomass. They have studied factors affecting dry matter production of forest trees in an attempt to approach underlying phYf'ical principles. This edition of Professor Satoo's book has been made possible the help of Dr John F. Hosner and the Virginia Poly technical Institute and State University who invited Dr Satoo to Blacksburg for three months in 1973 at about the time when he was in the final stages of preparing the Japanese version. Since then the explosion of world literature on forest biomass has continued to be fired by increasing shortages of timber supplies in many parts of the world as well as by a need to explore renewable sources of energy. In revising the original text I have attempted to maintain the input of Japanese work - much of which is not widely available outside Japan - and to update both the basic information and, where necessary, the conclusions to keep them in tune with current thinking. Those familiar with the Japanese original will find Chapter 3 largely rewritten on the basis of new work - much of which was initiated while Dr Satoo was in Blacksburg.

Download or read book Modelling Forest Development written by Klaus von Gadow and published by Springer Science & Business Media. This book was released on 2001-11-30 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key to successful timber management is a proper understanding of growth processes, and one of the objectives of modelling forest development is to provide the tools that enable foresters to compare alternative silvicultural treatments. In a managed woodland, the most important periodic disturbances are the thinning operations, which are often carried out at regular intervals and which usually have a significant effect on the future evolution of the resource. Thus, a realistic model of forest development includes both natural growth and thinnings. One of the outstanding features of this book is its inclusion of thinning models at varying levels of resolution and consideration of differences in foresters' tree marking behaviour. Other interesting aspects include regional resource forecasting approaches, generalized stem taper functions, generalized diameter-height relations, new ways of describing and reproducing forest spatial structures, crown modelling and iterative competition modelling. Worked examples and code are provided where appropriate. The intended readership is graduate students.
Download or read book Modern Time Series Analysis in Forest Products Markets written by Jens Abildtrup and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises fifteen papers exploring the consequences of applying modern time-series methods, particularly co-integrated time-series methods, for the analysis of forest economics problems. The methods represent the forefront of econometrics in this area, and the volume is the first of its kind. An introductory paper explains the econometrics of unit-root processes. Much of what follows in the other papers depends upon only a few of the ideas presented in the introduction. The volume includes tests of, e.g., the Law of One Price, land valuation models, demand and supply models, Granger-causality, and forecast models. The reader will learn a great deal about forest economies, particularly in Northern Europe, and about the practical use of modern time-series methods. The methods presented are applicable to other fields of economics. The volume is aimed at researchers in applied economics and as a supplement to (advanced) theoretical textbooks, mainly in Natural Resource Economics.
Download or read book Politics and Economics of Tropical High Forest Management written by Thorsten Treue and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the last two decades the loss of, in particular, tropical rainforest has alarmed the public in the developed parts of the world. The debate has been characterised by a lack of understand ing of the causes and effects of the process, leading to the prevailing reaction being unquali fied condemnation. Such attitude has even been observed among scientists, claiming suprem acy to biodiversity conservation. Many scientific analyses are available, but the basis for so ber debates and appropriate actions is still highly insufficient. Two recent international initia tives! will hopefully lead to improved knowledge of deforestation and forest degradation as they recognise the need for studies to critically investigate those issues. This book will pro vide useful input to the initiatives. In my opinion, the scientific analyses have not sufficiently promoted the understanding that the fate of tropical forests is first and foremost a concern of the governments of the countries in which the forests are situated. Tropical forests may be important to the global environment and their rich biodiversity may be a human heritage. But their main importance is their poten tial contribution to improving livelihood in the countries in question.

This book was released on 2013-12-01 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1996 a major six-year research programme, 'Economic Optimisation of Multiple-Use Forestry and Other Natural Resources' was implemented at Department of Economics and Natural Resources, The Royal Veterinary and Agricultural University (KVL), Copenhagen. The research is funded by KVL; The Danish Agricultural and Veterinary Research Council; The Danish Research Academy; The Danish Forest and Landscape Institute; The Danish Forest and Nature Agency; and The Danish Environmental Protection Agency. The overall objective of the research programme is to enhance the economic theory of sustainable multiple-use forestry and landscape management planning. Emphasis is on decision-making ! management planning from an economic point of view, the basic criterion being rationality as implemented by application of Operations Research methods with regard to sustainable and multiple use of forests and other natural resources in the landscape. The research programme benefits from collaboration agreements with University of California at Berkeley, Department of Agricultural and Resource Economics, and Oregon State University, Department of Forest Resources. As part of the research programme, a second international conference and workshop was held 6 - 12 August, 1998 at KVL, with the title: '2nd Berkeley-KVL Conference on Natural Resource Management -Design and Implementation of Multiple-Use Management'. This event was financed by The Danish Research Academy. Some of the papers presented were selected for peer-reviewing and subsequent publishing. The outcome is the present book in which no paper has been previously published.
