This book was released on 1987 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Relative change of several types of stem defects was studied over an 8-year period to determine the effects of crop-tree thinning on the development of tree quality. Special interest was given to changes in relative quality associated with defect indicators of crop trees compared to trees in unthinned plots. The relative quality classes of the crop trees went from "poor" to "medium" for red maple and "poor" to "good" for aspen. The oaks stayed in the poor classification and yellow-poplar remained unchanged in the medium classification. Results showed a decrease in the number of epicormic branches on the crop trees, and an increase in the size of live limbs.S3.

Results indicate that light thinning and crop-tree thinning produced higher quality and better grade trees than heavy thinning.S3.

Book excerpt: 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 excerpt: S2Three system 6 mill-size alternatives were designed and evaluated to determine their overall economic potential for producing standard-size hardwood blanks. The study focused on developing standard discounted cash flow measures. Internal rates of return ranged from about 15 to 35 percent after taxes. Secondary effort was directed at providing accounting cost summaries to facilitate cost comparison of standard-size blanks with rough-dimension stock. Cost per square foot of blanks ranged from about $0.88 to $1.19, depending on mill size and the amount of new investment required.S3.
