Continuing a tradition of excellence spanning over forty years, the Fifth Edition of Forest Measurements supplies forestry students at all levels with the concepts and methods they need for future success. The authors present timber measurement techniques applicable to any tree inventory regardless of management objectives. Assuming only some background in algebra and plane trigonometry, basic statistical concepts are included, ensuring that even introductory students benefit from the book’s concise explanations. Thorough coverage of sampling designs, land measurements, tree measurements, forest inventory field methods, and growth projections ensures utility for foresters throughout their education and beyond. Chapters on aerial photographs and GIS introduce readers to these powerful measurement tools, and the concluding chapter expands the techniques discussed to encompass other natural resources such as rangelands, wildlife, and water. Exceptionally readable and clear, the book includes many photographs and illustrations, numerous numerical examples, and a bibliography to enhance the reader’s understanding of the material.

Forest Management and Planning, Second Edition, addresses contemporary forest management planning issues, providing a concise, focused resource for those in forest management. The book is intermixed with chapters that concentrate on quantitative subjects, such as economics and linear programming, and qualitative chapters that provide discussions of important aspects of natural resource management, such as sustainability. Expanded coverage includes a case study of a closed canopy, uneven-aged forest, new forest plans from South America and Oceania, and a new chapter on scenario planning and climate change adaptation. Helps students and early career forest managers understand the problems facing professionals in the field today Designed to support land managers as they make complex decisions on the ecological, economic, and social impacts of forest and natural resources Presents updated, real-life examples that are illustrated both mathematically and graphically Includes a new chapter on scenario planning and climate change adaptation Incorporates the newest research and forest certification standards Offers access to a companion website with updated solutions, geographic databases, and illustrations

Public debate has stimulated interest in finding greater compatibility among forest management regimes. The debate has often portrayed management choices as tradeoffs between biophysical and socioeconomic components of ecosystems. Here we focus on specific management strategies and emphasize broad goals such as biodiversity, wood production and habitat conservation while maintaining other values from forestlands desired by the public. We examine the following proposition: Commodity production (timber, nontimber forest products) and the other forest values (biodiversity, fish and wildlife habitat) can be simultaneously produced from the same area in a socially acceptable manner. Based on recent research in the Pacific Northwest, we show there are alternatives for managing forest ecosystems that avoid the divisive arena of 'either-or' choices. Much of the work discussed in this book addresses two aspects of the compatibility issue. First, how are various forest management practices related to an array of associated goods and services? Second, how do different approaches to forest management affect relatively large and complex ecosystems?

Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.

Cost of private timber management practices in the United States are identified, and their relationship to timber production in general is highlighted. Costs across timber-producing regions and forest types are identified by forest type and timber management practices historically applied in each region. This includes cost estimates for activities such as forest establishment practices such as reforestation and afforestation on crop and pastureland. Establishment costs for reforestation in the Southern United States are less than in other regions, although regional differences in establishment costs are less evident in hardwood than in softwood stands. Also, included in the list of timber management costs ate the intermediate management treatments of precommercial thinning, herbicide, and fertilizer application. Intermediate management treatments are less costly in the southern United States than in other regions. Trends in timber management costs reported as part of the management costs reporting.

These projections reflect the consequences of recent changes in the Alaska forest sector & trends in markets for Alaska products. With the cancellation of the long-term contracts & the closure of the two southeast Alaska pulp mills, demand for Alaska national forest timber now depends on markets for sawn wood & the ability to export manufacturing residues & lower grade logs. Four scenarios are presented that display a range of possible future demands. The range in annual demand for timber from Alaska national forests is 48 to 370 million board feet of logs annually. Areas of uncertainty includes the prospect of continuing changes in markets & competition, & the rates of investment & innovation in manufacturing in Alaska. Illustrations.
