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.

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.

World population is increasing at an alarming rate and this has resulted in increasing tremendously the demand for tree products such as wood for construction materials, fuel and paper, fruits, oils and medicines etc. This has put immense pressure on the world’s supplies of trees and raw material to industry and will continue to do so as long as human population continues to grow. Also, the quality of human diet, especially nutritional components, is adversely affected due to limited genetic improvement of most of fruit trees. Thus there is an immediate need to increase productivity of trees. Improvement has been made through conventional breeding methods, however, conventional breeding is very slow due to long life cycle of trees. A basic strategy in tree improvement is to capture genetic gain through clonal propagation. Clonal propagation via organogenesis is being used for the production of selected elite individual trees. However, the methods are labour intensive, costly, and produce low volumes. Genetic gain can now be captured through somatic embryogenesis. Formation of embryos from somatic cells by a process resembling zygotic embryogenesis is one of the most important features of plants. In 1958, Reinert in Germany and Steward in USA independently reported somatic embryogenesis in carrot cultures. Since then, tremendous progress in somatic embryogenesis of woody and non-woody plants has taken place. It offers a potentially large-scale propagation system for superior clones.

Woody plants belong to various taxonomic groups, which are heterogeneous in morphology, physiology, and geographic distribution. OtheJWise, they have neither strong evolutionruy relationships nor share a conunon habitat. They are a primaIy source of fiber and timber, and also include many edible fruit species. Their unique phenotypic behavior includes a perennial habit associated with extensive secondary growth. Additional characteristics of woody plants include: developmental juvenility and maturity with respect to growth habit, flowering time, and morphogenetic response in tissue cultures; environmental control of bud dormancy and flowering cycles; variable tolerance to abiotic stresses, wounding and pathogens; and long distance transport of water and IRltrients. Woody plants, particularly tree species, have been the focus of numerous physiological studies to understand their specialized functions, however, only recently they have become the target of molecular studies. Recent advances in our understanding of signal transduction pathways for environmental responses in herbaceous plants, including the identification and cloning of genes for proteins involved in signal transduction. should provide useful leads to undertake parallel studies with woody plants. Molecular mapping techniques, coupled with the availability of cloned genes from herbaceous plants, should provide shortcuts to cloning relevant genes from woody plants. The unique phenotypes of these plants can then be targeted for improvement through genetic engineering.

Tropical climates, which occur between 23°30'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry forest lifezone, 33% is tropical moist forest, and 25% is wet or rain forest (Lugo 1988). The species diversity of these tropical habitats is very high. Raven (1976, in Mooney 1988) estimated that 65% of the 250,000 or more plant species of the earth are found in tropical regions. Of this floristic assemblage, a large fraction are woody species. In the well-collected tropical moist forest of Barro Colorado Island, Panama, 39. 7% (481 of 1212 species) of the native phanerogams are woody, arborescent species (Croat 1978). Another 21. 9% are woody vines and lianas. Southeast Asian Dipterocarp forests may contain 120-200 species of trees per hectare (Whitmore 1984), and recent surveys in upper Amazonia re corded from 89 to 283 woody species ~ 10 cm dbh per hectare (Gentry 1988). Tropical communities thus represent a global woody flora of significant scope.

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 unexploited 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 (Santalurn 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 transformation, and e) artificial or manufactured seed production.

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.

It is our conviction - based on many years of teaching and practical experience - that professional skill in forestry will develop more rea dily and more efficiently if forestry students are presented with a clear understanding, at an early stage, of the impact of the physical factors that both enhance and inhibit forestry activities. Tnis know ledge is best aquired by adressing the physical world of forestry with a set of analytical tools through which an almost infinite number of variables can be listed in order, be measured and their interaction be explored and resolved. This is the main purpose of this joint effort, presented in two volumes, Part I and Part II. Part I is analytic, written as a basic text for undergraduates in cour ses such as logging, transport, forest engineering and even forest ma nagement. It deals with the fundamentals of technology in forestry as determined by the physical environment. Briefly it can be visualized as the application of forestry wi thin the parameters: space, time and energy. Forestry is a process with a long time horizon. Free solar energy creates biomass which, with the aid of other forms of energy, is converted into products and services. A knowledge of the dependecies and interactions is indiGpensible for the forestry profession. The analytic approach serves two purposes: to bring about a clear un derstanding of the real world of forest and to develop tools through which efficiency and productivity can be explored and improved.
