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.

Maritimes Region and published by Fredericton, N.B. : Forestry Canada - Maritimes. This book was released on 1988 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intensive (whole-tree) harvesting of natural forest stands is widespread in the Maritime provinces. In some cases, the goal of whole-tree harvesting is to increase usable biomass, but often foliage and branch components are discarded at the landing site. This report examines the possible effects of whole-tree harvesting on long-term site productivity, and particularly on soil fertility. The report evaluates published data collected from different parts of the world concerning potential decline in soil fertility resulting from the loss of organic matter and base cations caused by different harvesting methods. Biomass and the amount of base cations that would be removed both by conventional and whole-tree harvesting are calculated. Published data from different stands in New Brunswick and Nova Scotia were used to examine the effect of species and site quality on base cation losses and the potential increase in soil acidification which would result from whole-tree harvesting. The consequences of high base cation losses, especially from the infertile acid soils of the region on long-term interfile acid soils of the region on long-term site productivity are discussed.

This book was released on 2015 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass harvesting extracts an increased amount of organic matter from forest ecosystems over conventional harvesting. Since organic matter plays a critical role in forest productivity, concerns of potential negative long-term impacts of biomass harvesting on forest productivity (i.e., changing nutrient/water cycling, aggravating soil properties, and compaction) have emerged. There is abundant prediction of long-term impacts of intensive biomass removal on forest productivity. However, the empirical knowledge and comprehensive understanding, especially on western forests, are limited thus far. Therefore, we utilize the available findings to evaluate potential impacts of increased biomass extraction on western forests. We compare biomass harvesting with natural disturbance regimes or conventional harvesting systems in terms of organic matter redistribution in order to evaluate the possible consequences of biomass harvesting on forest productivity. We review the role of organic matter on forest productivity and compare the organic matter redistribution or removal through biomass harvesting and natural disturbances or conventional harvesting to assess potential impacts. The summarized findings are: (1) the long-term impacts of intensive biomass harvesting will be mitigated by protection of the belowground organic matter; (2) biomass harvesting could result in the accelerated leaching of nutrients; and (3) immediate understory vegetation recovery can minimize potential negative impacts. Finally, sites sensitive to harvesting impacts (e.g., fine-textured soil and steep slopes) should be approached with caution and prior planning to minimize undesirable responses.

Download or read book Sustainable Use of Forest Biomass for Energy written by Dominik Röser and published by Springer Science & Business Media. This book was released on 2008-03-05 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: From time immemorial, firewood has been a very important source of energy for mankind. Later in history, wood for energy decreased its importance because of other more convenient and cheaper sources, mainly fossil fuels. Today, focus is again on use of forests as a producer of energy with main drivers being climate change, shortage and increasing prices of fossil fuel sources, and safety in energy supplies. However, intensive use of forest biomass is qu- tioned since fundamental ecological processes may be influenced negatively thus making up a trade-off with the benefits of using an otherwise sustainable source of energy. In this book, selected aspects of intensive use of forest b- mass for energy is treated with main focus on ecological aspects like maintenance of soil fertility, recycling of the combustion ash, inf- ence on biodiversity and pests, and economical aspects both at forest owners level and for society. Another focus point is the implemen- tion of this knowledge into decision support, recommendations and guidelines. The geographical scope is mainly the Nordic and Baltic region. The EU-financed project “Wood for Energy, - a contribution to the development of sustainable forest Management” (WOOD-EN- 1 MAN) , make up the frame for the book. Seven partners participated in the project: Forest & Landscape Denmark, Swedish University of Agricultural Sciences, Finnish Forest Research Institute, Norwegian Forest and Landscape Institute, Lithuanian Forest Research Institute, Latvian State Forestry Research Institute, and Estonian University of Life Sciences with Forest & Landscape Denmark as coordinator.

Download or read book Forest site and productivity written by B. Gessel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: A knowledge of forest site and forest productivity variables is fundamental to sound forest practice everywhere. The ability to identify sites and site problems correctly and manipulate productivity variables for maintenance or improvement of productivity is the basis of modern forest management. Although the basic facts regarding forest site and productivity apply throughout the world, the application of information and the response to manipulation vary greatly and depend on local forest conditions. The September 1981 World Congress of the International Union of Forest Research Organizations (IUFRO) in Kyoto, Japan was the occasion for the special meeting on Forest Site and Productivity sponsored by the IUFRO Site Group Sl.02. This meeting brought together forest site and productivity researchers from across the world to review current thought and the state of site research. Information not ordinarily available in one place was presented at this meeting. As organizer of the session, I decided to attempt to publish the papers in one volume. Arrangements were made with a publisher, Martinus Nijhoff, and also with the authors. The process of publication has taken longer than desirable, but the volume does appear at an opportune time coincident with the 1986 IUFRO World Congress in Yugoslavia. Material contained in this publication will set the stage for Site Group discussions at the 1986 meeting. This volume assembles the thought of forest research workers from many different countries and therefore many different kinds of forests.
