Much of the world's forested land is dominated by mixed-species stands. Understanding the complex structure and dynamics of these mixtures is a necessary step in the process of formulating appropriate silvicultural systems for their management. David M. Smith, Professor Emeritus of Silviculture at Yale University, has devoted much of his career to the study of the structure, development, and silvicultural treatment of these kinds of stands. This volume is presented by Professor Smith's collegues to honor the contributions he has made to the field. It contains both reviews of past work and results of current studies of mixed stands: topics range from analysis of forest dynamics in unmanaged stands to studies of silvicultural systems applied to mixtures, with examples drawn from boreal, temperate, and tropical regions. Much of the work stresses the importance of understanding the characteristic growth patterns of individual species within mixed stands, and how species interactions shape developmental patterns.

This book is an outcome of a research project on "Sustainable Forestry and the Environment in Developing Countries." The project has been run by Metsantutki muslaitos METLA -the Finnish Forest Research Institute since 1987 and will be completed this year. A major output by this project has so far been a report in three volumes on "Deforestation or development in the Third World?" The purpose of our multidisciplinary research project is to generate new knowl edge about the causes of deforestation, its scenarios and consequences. More knowledge is needed for more effective, efficient and equitable public policy, both at the national and intemationallevels in supporting sustainable forestry in develop ing countries. Our project has specifically focused on 90 tropical countries as one group and on three subgroups by continents, as well as the three case study countries, the Philippines, Ethiopia and Chile. The University of Joensuu has been our active partner in the Philippine study. We have complemented the three cases by the analyzes of Brazil and Indonesia, the two largest tropical forest-owning countries. Some other interesting country studies were annexed to complement our book both by geography and expertise. The United Nations University, World Institute for Development Economics Research, UNUIWIDER in Helsinki Finland has also been partly engaged. Most of the results from its project on "The Forest in the South and North in Context of Global Warming" will, however, be published later in a separate book."

The Sustainable Forestry Handbook is widely considered to be the essential aid to understanding and implementing sustainable forest management. Providing a clear and concise guide to the practicalities of implementing international standards for sustainable forest management, this fully updated second edition covers new Forest Stewardship Council requirements, High Conservation Value Forests, clearer requirements on pesticides and developments in policy and forest governance. Aimed at forest managers, and employing extensive cross referencing and easy-to-understand illustrations, this highly practical handbook explains in clear terms what the standards require forest managers to do and how they might go about implementing them.

Tran Van Nao (Editor) The last decade has witnessed a seriously increasing incidence of forest fires in many countries. Substantial economic and ecological losses have been incurred, although the estimation of total damage This has been due to the lack assessment has often been inaccurate. of standardized methods for collecting data on fire occurrence and area burnt, as well as information such as the value of the vegetation destroyed and restoration costs, and the implications for recreation, tourism and other social activities. The Mediterranean region was initially considered one of the most vulnerable to forest fires because of its' dry climate and strong winds. No region is immune to forest fires, however, and damage has been especially severe in areas where pine is the predominant species. Although forest fires are normally considered a national problem, they become an international one when they occur in border area forests or when the ecological impacts are felt over long distances. The potential for forest fires exists in every country -unless it is a complete desert - and for this reason, there is a need to promote better understanding of the fires, and closer cooperation between countries in controlling them.

Large areas of the warm, humid tropics in Southeast Asia, the Pacific, Latin America, the Caribbean, and Africa are hilly or mountainous. Jackson and Scherr (1995) estimate that these tropical hillside areas are inhabited by 500 million people, or one-tenth of the current world population, many of whom practice subsistence agriculture. The region most affected is Asia which has the lowest area of arable land per capita. Aside from limited areas of irrigated terraces, most of the sloping land, which constitutes 60% to 90% of the land resources in many Southeast Asian countries, has been by-passed in the economic development of the region (Maglinao and Hashim, 1993). Poverty in these areas is often high, in contrast to the relative wealth of irri gated rice farms in lowland areas that benefited from the green revolution. Rapid population growth in some countries is also exacerbating the problems of hillside areas. Increasingly, people are migrating from high-potential lowland areas where land is scarce to more remote hillside areas. Such migra tion, together with inherent high population growth, is forcing a transforma tion in land use from subsistence to permanent agriculture on fragile slopes, and is creating a new suite of social, economic, and environmental problems (Garrity, 1993; Maglinao and Hashim, 1993)."

Woody plants provide many challenges to the tissue culturist. Although there are many excellent tissue culture books and manuals available, these are generally strongly biased towards herbacious crops. Consequently, they often do not pay sufficient attention to the problems that specifically apply to in vitro culture of tree species. Culture of the latter often poses problems which are either absent or of lesser significance when culturing herbacious species. When trees in the field are used as explant source, the problems can be especially severe. For example, the physiological condition of the explants is difficult to control because of variation in weather and biotic factors. Furthermore, it is often difficult to obtain explants free of contaminants from field grown trees. Lack of genetic uniformity and maturation are additional problems one often has to deal with when culturing tree cells or tissues. These problems are emphasized in this text. In vitro culture of trees is not viewed in isolation. It is considered in conjunction with breeding, traditional cloning and other common tree improvement techniques. The text discusses theoretical as well as practical aspects of the in vitro culture of trees.

Research and publications on the potato crop have burgeoned since the first edition of this book was published in 1978. However, the warm reception of the first edition suggested that it had a useful part to play in promoting the scientific basis for understanding and improving the yield and quality of the crop. Since the first edition was out of print and a second reprint would not have taken into account the contributions made by research over the intervening years, it became obvious that a complete revision was necessary. There was, in particular, a need to take account of the rapid extension of interest in the crop into climates and farming systems with which it has not been traditionally associa, ted. Those involved with the crop will be sadly aware that a number of contributors to the first edition are no longer with us. Their contribution to our knowledge of the crop will however be a permanent legacy of their achievement. I would like to thank all those who have contributed to the book for their willingness to cooperate in the difficult task of bringing their particular subject up to date. This is even more noteworthy for the pressure of time appears to be almost an order of magnitude higher than it was when the first edition was tackled

The lntergovernmental Panel on Climate Change (IPCC) has recently summarized the state ofthe art in research on climate change (Climate Change 1995). The most up to date research findings have been divided into three volumes: * the Science ofClimate Change (working group I), * the Impacts, Adaption and Mitigation of Climate Change (working group II), and * the Economic and Social Dimensions ofClimate Change (working group III) There is a general consensus that a serious change in climate can only be avoided if the future emissions of greenhouse gases are reduced considerably from the business as usual projection and if at the same time the natural sinks for greenhouse gases, in particular that of CO , are maintained at the present level or 2 preferrably increased. Forests, forestry and forestry industry are important parts of the global carbon cycle and therefore they are also part of the mitigation potentials in at least a threefold way: 1. During the time period between 1980 and 1989 there was a net emission of CO from changes in tropical land use (mostly tropical deforestation) of 2 1. 6 +/- 1 GtC/a, but at the same time it was estimated that the forests in the northem hemisphere have taken up 0. 5 +/- 0. 5 GtC/a and additionally other terrestrial sinks (including tropical forests where no clearing took place) have been a carbon sink ofthe order of l. 3 +/- l.

Agroforestry systems are believed to provide a number of ecosystem services; however, until recently evidence in the agroforestry literature supporting these perceived benefits has been lacking. This volume brings together a series of papers from around the globe to address recent findings on the ecosystem services and environmental benefits provided by agroforestry. Specifically, this volume examines four major ecosystem services and environmental benefits: (1) carbon sequestration, (2) biodiversity conservation, (3) soil enrichment and (4) air and water quality. Past and present evidence clearly indicates that agroforestry, as part of a multifunctional working landscape, can be a viable land-use option that, in addition to alleviating poverty, offers a number of ecosystem services and environmental benefits. This realization should help promote agroforestry and its role as an integral part of a multifunctional working landscape the world over. The book should be particularly useful to students, professionals, researchers and policy makers involved in natural resource management, agroforestry, biodiversity conservation, and environmental management.

In the conflict between logging as a material resource and preservation the forests are becoming depleted throughout the world and this depletion is aggravated by the effects of air pollution. The concept of utilization is thus now being expanded to include vital societal values. These issues are nowhere more acute than in Central and Eastern Europe, where obsolete, poorly maintained industrial plant is common. Air pollutant levels are so high that one area has been called the Black Triangle. Timber is required in this region as a building material and logging for fuelwood is practised, giving rise to a complex linkage between industry, energy supply, deforestation, agriculture, value-added forestry products and economic development. This book presents current information on national and regional issues relating to environmental threats to forest land, focusing on: ecology, environment and science; forest ownership and management; forest product utilization; government and public agency roles. The recommendations, action items and the human network needed for regional-level implementation are detailed in `situation', `position' and `state of the art' papers. The final objective is to develop a plan of action to help abate the negative impacts while sustaining or expanding the forests, the economy and the energy sufficiency of the region.

'This book is a 'must have' for any biologists interested in the formation of wood, who might think of buying two copies - one for lab, where it will most definitely see heavy use, and one for the office as an excellent reference book.' - Malcolm M. Campbell, University of Oxford - New Phytologist

'...this book is highly recommended and should become a standard not only for libraries, but also as a personal copy for scientists working with woody tissues. It also serves as a rich source of scientific information regarding both structural and biochemical aspects of wood formation.' - Annals of Botany

This book draws together contributions from forest economists in the Research Triangle of North Carolina, with co-authors from institutions around the world. It represents our common belief that rigorous empirical analysis in an economic framework can inform forest policy. We intend the book as a guide to the empirical methods that we have found most useful for addressing both traditional and modem areas of concern in forest policy, including timber production and markets, multiple use forestry, and valuation of non-market benefits. 'The book editors and most chapter authors are affiliated with three institutions in the Research Triangle: the Southern Research Station of the USDA Forest Service (K. Abt, Butry, Holmes, Mercer, Moulton, Prestemon, Wear), the Department of Forestry at North Carolina State University (R. Abt, Ahn, Cubbage, Sills), and the Environmental and Natural Resource Economics Program of Research Triangle Institute (Murray, Pattanayak). Two other Triangle institutions are also represented among the book authors: Duke University (Kramer) and the Forestland Group (Zinkhan). In addition to our primary affiliations, many of us are adjunct faculty and/or graduates of Triangle universities. Many of our co-authors also graduated from or were previously affiliated with Triangle institutions. Thus, the selection of topics, methods, and case studies reflects the work of this particular network of economists, and to some degree, our location in the southeastern United States. However, our work and the chapters encompass other regions of the United States and the world, including Latin America and Asia.

Production of food to meet the demands of an ever-increasing human population in the world is the major task and challenge to agriculture today. The conventional methods of plant breeding alone can no longer cope with the situation. The success of any crop improvement program depends on the extent of genetic variability in the base population, but due to denuding of forests and agricultural land, the naturally occurring pool of germplasm is being depleted. An urgent need is therefore ap parent to create new variability and increase the genetic base of agricul tural crops. Agricultural biotechnology has progressed to a stage in the produc tion of plants where specific characteristics to improve their yield, ap pearance, disease-resistance, nutritional quality and adaptation to ad verse soil conditions can be built into the seed. This concept of built-in quality implies a continuous scientific endeavour to improve plant char acters using a wide range of possibilities, and it also implies a scrutiny of the materials and methods available in the world today."

Should damaged trees be clear cut and replanted or allowed to recover naturally? Is the deer herd large enough to survive hunting pressure? Managing forest resources entails numerous decisions. Making these decisions intelligently requires sound information about the resource in question. Ideally, assessments should be based on the entire population involved. However, the costs in time and money often prevent this, and evaluations - or sampling - are done on a small portion of the whole. The most complete treatment of systematic sampling in one volume, Forest Sampling Desk Reference explains the uses and limitations of individual sampling designs in forest inventory operations. This text contains detailed derivations of the most commonly used statistical methods in forestry. It provides examples that highlight the statistical methods. The author covers probability and probability distributions and the development of logical regression models. The text discusses systematic sampling, describing its benefits and shortcomings in detail. It provides an in depth examination of the controversial 3-P sampling procedure. The validity and strength of sampling results vary from option to option, along with their costs in terms of money and time. Before selecting a sampling procedure you need to know their strengths and weaknesses in relation to their expense. Forest Sampling Desk Reference supplies the background necessary for making these decisions.

On a Sustainable Future of the Earth s Natural Resources is divided into three sections, with individual chapters contributed by experts on diff erent facets of the earth sciences, natural resources management and related issues. The first section focuses on the status of Earth s resources; land, water, biota and atmosphere. Reviews on the rate of exploitation and the need to conserve these resources for future sustenance are also covered in this section. Th e following section includes chapters elucidating environmental, ecological, climatological and anthropological pressures on sustained nourishment with the Earth s resources. The last section describes management practices, issues and perspectives on sociological, legal, administrative, ICT and strategic efforts that need to be implemented in order to sustain our natural resources. This book covers a broad spectrum of the Earth s resources and sustenance, offering a comprehensive perspective on their past, present and future.

The papers in this book were 'in a preliminary version' presented at an international con ference May 21-25, 2002 in Gilleleje, Denmark. It was a joint event, namely the biennial meeting of the Scandinavian Society of Forest Economics and the 3rd Berkeley-KVL Con ference. The Scandinavian Society of Forest Economics (SSFE) was established in 1958 as a forum for forest economists in the Nordic countries to meet and exchange ideas on research and education. Alternating between Denmark, Finland, Norway and Sweden, biennial ordinary meetings have taken place ever since. The number of participants has increased from 10-15 in the first decade to more than 80 in 2002. In the last two decades prominent researchers from outside Scandinavia have been invited to present papers at the biennial meetings and also to participate in ad hoc working groups. The Berkeley-KVL part of the conference is based on a research collaboration between The Royal Veterinary and Agricultural University (KVL), Copenhagen, University of Cali fornia at Berkeley, and Oregon State University. It was initiated in 1993 within the frame work of a research programme at KVL: 'Stochastic Decision Analysis in Forest Manage ment' and since 1996 extended to the programme 'Economic Optimisation of Multiple-Use Forestry and Other Natural Resources'."

A new era in wildland fuel sciences is now evolving in such a way that fire scientists and managers need a comprehensive understanding of fuels ecology and science to fully understand fire effects and behavior on diverse ecosystem and landscape characteristics. This is a reference book on wildland fuel science; a book that describes fuels and their application in land management. There has never been a comprehensive book on wildland fuels; most wildland fuel information was put into wildland fire science and management books as separate chapters and sections. This book is the first to highlight wildland fuels and treat them as a natural resource rather than a fire behavior input. Moreover, there has never been a comprehensive description of fuels and their ecology, measurement, and description under one reference; most wildland fuel information is scattered across diverse and unrelated venues from combustion science to fire ecology to carbon dynamics. The literature and data for wildland fuel science has never been synthesized into one reference; most studies were done for diverse and unique objectives. This book is the first to link the disparate fields of ecology, wildland fire, and carbon to describe fuel science. This just deals with the science and ecology of wildland fuels, not fuels management. However, since expensive fuel treatments are being planned in fire dominated landscapes across the world to minimize fire damage to people, property and ecosystems, it is incredibly important that people understand wildland fuels to develop more effective fuel management activities.

Trees and woodlands are an integral part of Britains heritage and culture, as well as an invaluable environmental and ecological resource. In an increasingly urbanized British population, romantic notions of bluebell-carpeted woods and deep-coloured wooded hillsides during autumn do not come easily. Instead, images of forgotten corners of land with a few sycamore trees and lots of brambles, or an area of dark, intimidating conifers are more common. The wide variety of types of woodland, whether closely managed or naturally-occuring, provide important habitats for a huge range of flora and fauna. This text explores the history and ecology of British woodlands, and explains why they are such a valuable resource. It offers a practical guide to issues of ecology of woodland habitats and organisms; conservation and management; coppicing, pasture woodland and commercial forestry; woodland grazing, ride management and recration in woodlands. Featuring illustrated species boxes as well as a full species list, notable sites with location maps and pictures, suggested projects and a full glossary, students and environmentalists should gain an understanding of the historical and present-day im
