Book Description
Excerpt from Direct Costs of Silvicultural Treatments on National Forests, 1975-78 Four types of silvicultural treatments, or practices, were studied: site preparation, reforestation, intermediate treat ment, and slash disposal. The unit of observation was a single contiguous treatment area, or tract, that may be all or part of the entire service contract. A total of observations were received and analyzed from report forms sent to National Forests. Of that total, 307 were discarded because of missing values for critical variables. All results were reported in 1978 dollars. Cost predictions were developed for nine of the more frequently encountered silvicultural treatment and forest type group combinations. They express cost per treatment area as a function of treatment and site characteristics. These equations include only those variables that are commonly known or that can be easily estimated before a treatment is carried out.

Book Description
Silviculture: Concepts and Applications reflects a belief that all the tools of silviculture have a useful role in modern forestry. Through careful analysis and creative planning, foresters can address a wide array of commodity and nonmarket interests and opportunities while maintaining dynamic and resilient forests. A landowner’s needs, circumstances, and site conditions guide a silviculturist’s judgment and decision making in finding the best ways to integrate the biologic-ecologic, economic-financial, and managerial-administrative requirements at hand. The Third Edition of this influential text provides a foundational basis for rigorous discussion of techniques. The inclusion of numerous real-world examples and balanced coverage of past and current practices broadens the concept of silviculture and the ways that managers can use it to address both traditional and emerging interests in forests. A thorough discussion of new and proven interpretations increasingly directs the attention of foresters toward the role silviculture plays in creating, maintaining, rehabilitating, and restoring forests that can sustain an expanding variety of ecosystem services.

Book Description
This timely collection of essays - written by nine recognized forestry and environmental specialists - tells the story of the conservation, use, and changes in the Commonwealth's forests over time. The book traces the development of pre-settlement, colonial, and post-Revolutionary War forest practices, and concludes with recommendations as to how history might be used to inform and shape future policy. Underscored is the importance of private and local leadership, such as the unique Massachusetts town forest movement. Economic contributions and educational programs are detailed, as well as the ways Massachusetts' leadership has influenced national forestry. Written for the layperson, and reflecting the particular experience and style of each contributor, the history will appeal to a range of readers from local conservation activists to forestry professionals and policymakers.
