USDA Forest Service Experimental Forests and Ranges (EFRs) are scientific treasures, providing secure, protected research sites where complex and diverse ecological processes are studied over the long term. This book offers several examples of the dynamic interactions among questions of public concern or policy, EFR research, and natural resource management practices and policies. Often, trends observed – or expected -- in the early years of a research program are contradicted or confounded as the research record extends over decades. The EFRs are among the few areas in the US where such long-term research has been carried out by teams of scientists. Changes in society’s needs and values can also redirect research programs. Each chapter of this book reflects the interplay between the ecological results that emerge from a long-term research project and the social forces that influence questions asked and resources invested in ecological research. While these stories include summaries and syntheses of traditional research results, they offer a distinctly new perspective, a larger and more complete picture than that provided by a more typical 5-year study. They also provide examples of long-term research on EFRs that have provided answers for questions not even imagined at the time the study was installed.

Although the majority of the world’s forest ecosystems are dominated by uneven-sized multi-species stands, forest management practice and theory has focused on the development of plantation monocultures to maximize the supply of timber at low cost. Societal expectations are changing, however, and uneven-aged multi-species ecosystems, selectively managed as Continuous Cover Forestry (CCF), are often believed to be superior to monocultures in addressing a wide range of expectations. This book presents methods which are relevant to CCF management and planning: analysing forest structures, silvicultural and planning, economic evaluation, based on examples in Europe, Asia, Africa and North and South America.

This book has been developed as a forest inventory textbook for students and could also serve as a handbook for practical foresters. We have set out to keep the mathematics in the book at a fairly non-technical level, and therefore, although we deal with many issues that include highly sophisticated methodology, we try to present first and foremost the ideas behind them. For foresters who need more details, references are given to more advanced scientific papers and books in the fields of statistics and biometrics. Forest inventory books deal mostly with sampling and measurement issues, as found here in section I, but since forest inventories in many countries involve much more than this, we have also included material on forestry applications. Most applications nowadays involve remote sensing technology of some sort, so that section II deals mostly with the use of remote sensing material for this purpose. Section III deals with national inventories carried out in different parts of world, and section IV is an attempt to outline some future possibilities of forest inventory methodologies.
