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.

An increase in the demand for wood results in improved recovery and less residual biomass in the forests. Paradoxically, interest in forest residue as a renewable source of raw material seems to be in a reverse ratio to its availability in a certain area. Finland and Sweden are probably more dependent on forestry and forest in dustries than any other developed countries in the world. A sufficiency of raw ma terial for integrated forest industries is vital for the national economy of both countries, and a great deal of attention is being paid to the long-term potential of unutilized biomass left behind in logging operations. Furthermore, since these countries possess no reserves of fossil fuels, and since their per-capita consump tion of primary energy is exceptionally high, they also consider unmerchantable forest biomass a realistic source of indigenous energy. A joint Nordic research project on harvesting and utilization of logging residue was carried out in 1969-1976 under the auspices of the Nordic Research Council on Forest Operations. This fruitful cooperation soon gave rise to related national projects in Sweden, Finland, Norway, and Denmark, stimulating further research and producing practical applications. Concurrently, particularly after the worldwide energy crisis in 1973, research on all aspects of utilization of forest bio mass mushroomed in the United States, Canada, and the Soviet Union. An ex plosive increase occurred in both the number and diversity of biomass studies.

Existing literature on procedures for estimating tree biomass for northeastern tree species includes a number of research studies that are specific and localized. As a result, there is little consistency in these estimation procedures, which are largely in the form of regression equations. In addition, many species are ignored that need to be quantified when inventories of forest resources are conducted over extensive areas. This makes it difficult to determine the most appropriate biomass-estimation procedures. In this paper, an evaluation is made of prediction models and their application over the entire range of northeastern tree species. Recommendations are also made on procedures for the more nontimber oriented elements of total forest biomass-shrub biomass, foliage biomass, stump and root biomass, and biomass on unproductive forest land.

Forests must be measured if they are to be managed and conserved properly. This book describes the essential principles of modern forest measurement, whether using simple hand-held equipment or sophisticated satellite imagery. It particularly focuses on measuring forest biomass over large forest areas, a key aspect of climate change studies, as well as the volumes of wood that are commercially available. Written in a straightforward style, it will be accessible to anyone who works with forests, from the professional forester to the layperson. It considers not only how and why forests are measured but also the scientific basis of the measurements taken.

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.

Mobilisation of Forest Bioenergy in the Boreal and Temperate Biomes: Challenges, Opportunities, and Case Studies features input from key international experts who identify and analyze the main opportunities and roadblocks for the implementation of sustainable forest biomass supply chains in the boreal and temperate regions. It draws from responses to surveys that were sent to specialists from different countries, compares models of bioenergy deployment, and discusses different types of bioenergy carriers. Efficiency and profitability of the supply chain are analyzed and the scale and level of confidence of feedstock inventory estimates are highlighted. Logistics and ecological and socio-economic footprints are also covered. This book provides a synthesis of the scientific and technical literature on specific aspects of forest biomass supply chains, and quantifies future potentials in comparison to estimates provided by other sources and the targets for bioenergy production set by various organizations (IEA, IPCC, etc.). Finally, the book proposes recommendations for practitioners, policymakers, and future research. This approach makes the book especially relevant for professionals, policymakers, researchers, and graduate students in the field of bioenergy conversion and management, as well as those interested in sustainable management of natural resources. Presents foundational theory, examples and lessons learned, drawing on scientific and technical literature, as well as surveys conducted among stakeholders from various countries of the boreal and temperate biomes Provides best practices, insights, and recommendations through an integrative framework that encompasses various aspects of forest biomass supply chain, at different scales, and looking at a broad geographical and geopolitical range Compares contrasting history, policy context, and level of forest bioenergy development in several countries through several case studies Analyzes the efficiency and profitability of the supply chain, highlighting the scale and level of confidence of feedstock inventory estimates
