This report provides a general overview of current log sort yard operations in the United States, including an extensive literature review and information collected during on-site visits to several operations throughout the nation. Log sort yards provide many services in marketing wood and fiber by concentrating, merchandising, processing, sorting, and adding value to logs. Such operations supply forest products firms with desired raw materials, which helps improve their bottom line by reducing the number of marginal logs processed. Ultimately, sorting logs leads to better use of the available timber resources. Successful log sort yards are self-sufficient and have well-established markets and a steady supply of wood. Log sort yard concepts and analyses described in this report have broad applications.

Salvage logging—removing trees from a forested area in the wake of a catastrophic event such as a wildfire or hurricane—is highly controversial. Policymakers and those with an economic interest in harvesting trees typically argue that damaged areas should be logged so as to avoid “wasting” resources, while many forest ecologists contend that removing trees following a disturbance is harmful to a variety of forest species and can interfere with the natural process of ecosystem recovery. Salvage Logging and Its Ecological Consequences brings together three leading experts on forest ecology to explore a wide range of issues surrounding the practice of salvage logging. They gather and synthesize the latest research and information about its economic and ecological costs and benefits, and consider the impacts of salvage logging on ecosystem processes and biodiversity. The book examines • what salvage logging is and why it is controversial • natural and human disturbance regimes in forested ecosystems • differences between salvage harvesting and traditional timber harvesting • scientifically documented ecological impacts of salvage operations • the importance of land management objectives in determining appropriate post-disturbance interventions Brief case studies from around the world highlight a variety of projects, including operations that have followed wildfires, storms, volcanic eruptions, and insect infestations. In the final chapter, the authors discuss policy management implications and offer prescriptions for mitigating the impacts of future salvage harvesting efforts. Salvage Logging and Its Ecological Consequences is a “must-read” volume for policymakers, students, academics, practitioners, and professionals involved in all aspects of forest management, natural resource planning, and forest conservation.

The Management of Industrial Forest Plantations. Theoretical Foundations and Applications provides a synthesis of current knowledge about industrial forestry management planning processes. It covers components of the forest supply chain ranging from modelling techniques to management planning approaches and information and communication technology support. It may provide effective support to education, research and outreach activities that focus on forest industrial plantations management. It may contribute further to support forest managers when developing industrial plantations management plans. The book includes the discussion of applications in 26 Management Planning in Actions boxes. These applications highlight the linkage between theory and practice and the contribution of models, methods and management planning approaches to the efficiency and the effectiveness of industrial plantations management planning.

Across the inland West, forests that once seemed like paradise have turned into an ecological nightmare. Fires, insect epidemics, and disease now threaten millions of acres of once-bountiful forests. Yet no one can agree what went wrong. Was it too much management—or not enough—that forced the forests of the inland West to the verge of collapse? Is the solution more logging, or no logging at all? In this gripping work of scientific and historical detection, Nancy Langston unravels the disturbing history of what went wrong with the western forests, despite the best intentions of those involved. Focusing on the Blue Mountains of northeastern Oregon and southeastern Washington, she explores how the complex landscapes that so impressed settlers in the nineteenth century became an ecological disaster in the late twentieth. Federal foresters, intent on using their scientific training to stop exploitation and waste, suppressed light fires in the ponderosa pinelands. Hoping to save the forests, they could not foresee that their policies would instead destroy what they loved. When light fires were kept out, a series of ecological changes began. Firs grew thickly in forests once dominated by ponderosa pines, and when droughts hit, those firs succumbed to insects, diseases, and eventually catastrophic fires. Nancy Langston combines remarkable skills as both scientist and writer of history to tell this story. Her ability to understand and bring to life the complex biological processes of the forest is matched by her grasp of the human forces at work—from Indians, white settlers, missionaries, fur trappers, cattle ranchers, sheep herders, and railroad builders to timber industry and federal forestry managers. The book will be of interest to a wide audience of environmentalists, historians, ecologists, foresters, ranchers, and loggers—and all people who want to understand the changing lands of the West.

It is the rare book that remains in print for nearly fifty years, earning wide acclaim as a classic. The Forest Ranger has been essential reading for generations of professionals and scholars in forestry, public administration, and organizational behavior who are interested in the administration of public lands and how the top managers of a large, dispersed organization with multiple objectives like the Forest Service shape the behavior of its field officers into a coherent, unified program. Published as a special reprint in conjunction with the 100th anniversary of the U.S. Forest Service, The Forest Ranger is as relevant and timely today as when it was first issued in 1960. In addition to the original text, this special reprint of The Forest Ranger includes two new forewords and an afterword that highlight how much we have learned from Herbert Kaufman. The first foreword, by Harold K. (Pete) Steen, former president of the Forest History Society, considers the book's impact on the forestry community and explains its continued relevance in light of changes in the culture and mission of today's Forest Service. The second, by Richard P. Nathan, codirector of the Rockefeller Institute of Government, considers the book's contribution to our understanding of administrative and organizational behavior. The new afterword by author Herbert Kaufman describes how his landmark study came into being and offers a candid assessment of how his theories about the agency's operations and its future have held up over time. In 1960, the Forest Service had a well-deserved reputation for excellence, and The Forest Ranger was a seminal analysis of the hows and whys of its success. Kaufmanalso warned, however, that an organization so unified and well adapted to its environment would have difficulties navigating social change. He was right in his concerns: the environmental, civil rights, and women's movements have all presented challenges to the character and purpose of the Forest Service, ultimately changing the organization in subtle and not-so-subtle ways. Now, as then, The Forest Ranger is a striking and prescient case study of how a complex organization operates and evolves over time.

Forest Analytics with R combines practical, down-to-earth forestry data analysis and solutions to real forest management challenges with state-of-the-art statistical and data-handling functionality. The authors adopt a problem-driven approach, in which statistical and mathematical tools are introduced in the context of the forestry problem that they can help to resolve. All the tools are introduced in the context of real forestry datasets, which provide compelling examples of practical applications. The modeling challenges covered within the book include imputation and interpolation for spatial data, fitting probability density functions to tree measurement data using maximum likelihood, fitting allometric functions using both linear and non-linear least-squares regression, and fitting growth models using both linear and non-linear mixed-effects modeling. The coverage also includes deploying and using forest growth models written in compiled languages, analysis of natural resources and forestry inventory data, and forest estate planning and optimization using linear programming. The book would be ideal for a one-semester class in forest biometrics or applied statistics for natural resources management. The text assumes no programming background, some introductory statistics, and very basic applied mathematics.
