It is our conviction that professional skill in forestry will develop more readily and more efficiently if forestry students are presented with a clear understanding of the im pact of the physical factors that both enhance and inhibit forestry activities. Part I is analytic, written as a basic text for undergradu ates in courses such as logging, transport, forest engineer ing and even forest management. It deals with the fundamen tals of technology in forestry as determined by the physical environment. The analytic approach serves two purposes, to bring about a clear understanding of the real world of the forest and to develop tools through which efficiency and productivity can be explored, understood and improved. The principal author of this volume was Prof. Ulf sundberg. Part II discusses in some detail a wide variety of practical problems encountered by foresters. It describes harvesting systems and the principles of management and control of forest operations. The influence of the forest on operations is described at length, the terrain, topography, forest soils as well as the engineering characteristics of trees and forest stands. It also considers the impact of oper ations on the forest. The principal author of this volume was Dr. Ross Silversides. Chapters 11, 12 and 13 were written by-Prof. Sundberg.

In most breeding programs of plant and animal species, genetic data (such as data from field progeny tests) are used to rank parents and help choose candidates for selection. In general, all selection processes first rank the candidates using some function of the observed data and then choose as the selected portion those candidates with the largest (or smallest) values of that function. To make maximum progress from selection, it is necessary to use a function of the data that results in the candidates being ranked as closely as possible to the true (but always unknown) ranking. Very often the observed data on various candidates are messy and unbalanced and this complicates the process of developing precise and accurate rankings. For example, for any given candidate, there may be data on that candidate and its siblings growing in several field tests of different ages. Also, there may be performance data on siblings, ancestors or other relatives from greenhouse, laboratory or other field tests. In addition, data on different candidates may differ drastically in terms of quality and quantity available and may come from varied relatives. Genetic improvement programs which make most effective use of these varied, messy, unbalanced and ancestral data will maximize progress from all stages of selection. In this regard, there are two analytical techniques, best linear prediction (BLP) and best linear unbiased prediction (BLUP), which are quite well-suited to predicting genetic values from a wide variety of sources, ages, qualities and quantities of data.

Interest and initiatives in agroforestry education and training, as in other aspects of agroforestry development, have increased tremendously during the past decade. Coordination of such educational activities was initiated by the first international workshop on education in agroforestry organized by the International Council for Research in Agroforestry (ICRAF) in Decem ber 1982, at Nairobi, Kenya. Since then, agroforestry has been incorporated into the curricula of many educational and training institutions around the world. Moreover, several institutions have developed entire academic programs specifically in agroforestry. However, most of these activities are still isolated initiatives, without common strategies or philosophies. This second international agroforestry workshop was therefore planned to pro vide a forum for reviewing progress, sharing programs and experiences, and planning and coordinating future directions in agroforestry education and training. The main objectives were to review the on-going programs, to assess the scope of professional education and training in relation to the perceived needs of trained personnel, to recommend guidelines for further program development, and to establish networking among institutions and agencies involved in agroforestry education and training. These proceedings contain the keynote papers, regional/country presenta tions and conclusions and recommendations of the International Workshop on Education and Training in Agroforestry held at the University of Florida, Gainesville, USA in December, 1988. The strategy of the workshop was to facilitate focused discussion on identified issues by an invited group of world leaders in agroforestry education and training.

In this book I have collected many reports on the properties of bamboo. Since I started bamboo research in 1974, I have collected many publications on bamboo. However, in contacts with other researchers I became aware of the fact that several of these publications were unknown to them. Consequently their activities in research or in bamboo projects had to start at a lower level than if they had known some of these publications. Therefore, I discussed the need for a book like this with several colleagues, and I decided to start writing. In this book I present data on properties, as published by resear chers. Certainly it is not complete; e.g. the proceedings of the bamboo workshop in Cochin in November 1988 are not included; they arrived just too late to be taken into account. On the other hand, in writing this preface I realize I have forgotten my own thesis. I do apologize to any colleague whose relevant report is not taken into account as well. I like to express my feelings of respect to the board of my faculty: they allowed me to spend so much time on this book, and they gave a considerable financial support for the printing costs.

Woody plants provide many challenges to the tissue culturalist. 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.

This handbook was designed as a reference tool for forest geneticists, tree breeders and other tree improvement personnel, as well as a textbook for university courses and short-courses at the graduate level in quantitative genetics. The chapters focus on the decision points faced by quantitative geneticists and breeders in designing programs and analyzing data. Beginning with a justification for the use of quantitative genetics in decision making in tree improvement programs, the book continues with a brief presentation of fundamental principles, followed by discussions and evaluations of mating designs and field test designs, the use of best linear predictors to estimate breeding values, the use of computer programs in the analysis of variance for genetic information, the deployment of genetically improved stock for capturing gains, the use of economic models for program justification, and the development of seed transfer guidelines.

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 colleagues to honour 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 analyses 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 volume contains 19 invited papers from the International Symposium on Population Genetics of Forest Trees which was held in Corvallis, Oregon, USA, July 31-August 2, 1990. The papers summarize and review the contributions of biochemical genetic markers to the understanding of population genetic structure and evolutionary biology of forest trees, and identify promising areas for future research. Applications of biochemical genetic markers in forestry practice - including breeding zone designation - seed orchard management, and monitoring of genetic resources are also addressed. In addition, the potential of DNA as a biochemical marker is discussed. This overview of the field of population genetics of forest trees will be of great interest to researchers in forest biology as well as forestry practitioners.

Agroforestry research and development in Australia has been largely fragmented and many of the research results have never been published and are unknown. The purpose of this volume is to comprehensively review all of the research that has taken place in the field of agroforestry in Australia, including previously unpublished results, providing readers with the latest technical and economic information about using trees in agriculture for the control of salinity and erosion, for shelter and shade, and for the production of timber, fodder and minor forest productions. The book provides information concerning planted trees within all of these categories and includes special review of the management of native vegetation on farms. These papers also examine research needs where appropriate. This book stems from the National Australian Conference on "The Role of Trees in Sustainable Agriculture" which took place in Albury, Victoria, Australia in October, 1991. Each national review paper is based upon a summary of six or more state review research and development papers, prepared specifically for the national conference.The book should provide readers with a comprehensive overview of agroforestry research in Australia, which is introduced and summarized in the first chapter.

The quality of human life has been maintained and enhanced for generations by the use of trees and their products. In recent years, ever rising human population growth has put tremendous pressure on trees and tree products; growing awareness of the potential of previously un exploited tree resources and environmental pollution have both accelerated development of new technologies for tree propagation, breeding and improvement. Biotechnology of trees may be the answer to solve the problems which cannot be solved by conventional breeding methods. The combination of biotechnology and conventional methods such as plant propagation and breeding may be a novel approach to improving and multiplying in large number the trees and woody plants. So far, plant tissue culture technology has largely been exploited in the propagation of ornamental plants, especially foliage house plants, by com- mercial companies. Generally, tissue culture of woody plants has been recal- citrant. However, limited success has been achieved in tissue culture of angiosperm and gymnosperm woody plants.A number of recent reports on somatic embryogenesis in woody plants such as Norway spruce (Picea abies), Loblolly pine (Pinus taeda), Sandalwood (Santalum album), Citrus, Mango (Mangifera indica), etc. offer a ray of hope of: (a) inexpensive clonal propa- gation for large-scale production of plants or "emblings" or "somatic embryo plants"; (b) protoplast work; (c) cryopreservation; (d) genetic transforma- tion; and (e) artificial or manufactured seed production.

The volumes in this series provide an update to progress on somatic embryogenesis in woody plants including both angiosperm and gymnosperm trees. In the past, most of the information on this subject was scattered in proceedings volumes, journals and biotechnology books. It has been difficult for the researchers and students to obtain comprehensive information on this rapidly growing subject from a single source. These books enable readers to get a clear view of this subject on historical, anatomical, physiological, biochemical and molecular aspects, and applications including protoplasts, cryopreservation, manufactured seed (artificial seed), genetic transformation, bioreactors, mutations, and future uses in forest plantations. Each selected woody plant mentioned is briefly introduced first, covering botany and genetics, importance and geographical distribution, breeding problems and in vitro propagation and problems of each selected woody plant. This is followed by a description of the initiation and maintenance of embryogenic cultures, embryo development and germination, and field trials (if any) of these plants.The books are intended for graduate students and researchers in forestry and horticulture as well as biotechnologists.

Agroforestry research is central to developing methods for the sustainable use of natural renewable resources, evolving to address the needs of the coming century. It is necessary to consolidate the scientific gains made in process-oriented research and to develop a policy framework to encourage the adoption of sustainable land use practices. Agroforestry plays an important role in conserving forest resources, reducing the need for deforestation. Further, if "forest" is broadly defined as tree cover, agroforestry will also increase the proportion of woody biomass in farming landscapes. The papers selected for inclusion in this text establish agroforestry as an interdisciplinary science focused on the practical imperative of assisting farmers, forest dwellers and landscape-level planners to achieve sustainable food, fuel and timber production into the 21st century.

The volume analyzes the accumulated state of wildland fire science in the boreal forest zone of Eurasia. The volume is mainly based on research achievements from the former Soviet Union and on ongoing programs of the Russian Academy of Sciences. Selected contributions from fire ecology, remote sensing and atmospheric chemistry from boreal Fennoscandia and North America provide the latest state of research and the link to the global importance of fire in the boreal zone. In the context of global change research, boreal fire science is receiving increasing attention, e.g. related to prehistoric, historic and modern influences of fire on vegetation dynamics, the role of fire in the atmosphere, biogeochemical cycles and climate (carbon cycle, chemistry of the free troposphere and stratosphere, e.g. tropospheric ozone increase, stratospheric ozone depletion). The volume provides a basic analysis for upcoming international and interdisciplinary studies at regional and global scale, e.g. in the frame of the International Geosphere-Biosphere Programme (IGBP), particularly the IGBP Northern Eurasia Study, and the activities of the International Boreal Forest Research Association (IBFRA).

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.

The Global Biodiversity Strategy, signed in 1992 in Rio de Janeiro, and the resolutions at the Ministerial Conferences on the Protection of Forests in Europe in Strasbourg, 1990, and Helsinki, 1993, commit the signatory states to monitor nationally the state of biodiversity and to sustain the characteristic natural variation in the country. Sustainability and long-term planning are the two terms which best describe the philosophy of traditional forest management practices. However, the traditional planning techniques are not primarily developed to maintain sustainability of biodiversity. The gap between the international commitments and the practices in forest assessment and management is obvious. This publication presents experience in methodology for assessing and monitoring the variation of ecosystems and habitats in relation to biodiversity conservation and for integrating biodiversity in regional planning of forest management and land use.The state of the field of natural resource assessments with special reference to forest biodiversity is reviewed; progress in integrating data on biodiversity in forest management planning is presented; and the information needs regarding biodiversity conservation and the question to what degree assessment methods for forest biodiversity can be simplified for practical applications are discussed. The book is intended for researchers and practitioners in the field of forest and environmental planning and environmental policies.

In this volume, international experts describe biological, ecological, economic and social aspects of planted forests. Representative types of planted forests are described and discussed, technical and social aspects are considered, and case studies depict the variety of purposes and uses of planted forests. Authors discuss the nature of planted forests of representative species world-wide, basic biology and ecology of plantations, and economic and social considerations in landscapes where planted forests contribute to potentially sustainable societies. The authors dissect temperate and tropical forests, developed and developing nations, and all levels of intensity of planting and managing forest trees. This compilation of views and viewpoints about planted forests provides a fresh, broad outlook on trees planted for myriad purposes. Forest scientists and managers, policy experts, development officials and interested citizens will find information of value and stimuli for thinking about forests of the future.

This volume comprises a selection of original contributions presented at a workshop held in Montpellier, France, in June 1997. The two main objectives of the workshop were, firstly, to bring together what is understood about the processes underlying agroforestry practice, and, secondly, to provide a forum to explore relevant models and modelling approaches. The workshop was also able to play a role in examining the agroforestry systems encountered in temperate and Mediterranean areas, including both traditional and more innovative agroforestry practices. The main aspects discussed were ecological interactions amongst components, environmental impact, economics and policy modelling.

This text is a collection of papers presented at the international symposium on forest sector analysis held in Miyazaki, Japan, in 1998. It is structured with three themes - understanding global forest sector issues, discussing the contribution of modeling efforts to forest sector analysis, and discussing the role of Japanese forest policy in a global sense. The most important features are the case studies using various types of forest sector models. From a modeling perspective, changes in modeling efforts include more detail of spatial and multiple market levels, intergenerational welfare concerns, non-market valuation issues, and explicit treatment of the uncertainty inherent in both the policy process and in the biophysical systems. The reader of this book will benefit not only from presentation of forest utilization issues in different nations, but also from the interrelatedness of the theory and application of forest sector modeling.
