Excerpt from Timber Resource of Minnesota's Aspen-Birch Unit, 1977 Fieldwork for the 197 7 Minnesota Forest Survey began in July, 1974 and was completed in July, 1978. Reports on the three previous surveys of Minnesota's timber resource are dated 1936, 1953, a'nd 1962. Similar Resource Bulletins containing statistical highlights and detailed tables on the timber resource of the other Survey Units in Minnesota (see cover) are also available. These will provide the basis for a comprehensive analysis of the timber resource of the entire State which will be published as a sepa rate report. More accurate survey information was obtained during the 1977 survey than otherwise would have been feasible because of intensified field sampling made possible by funding and man power provided the North Central Station by the State Legisla ture through the Minnesota Department of Natural Resources. The Department also assisted in a canvass of primary wood using plants in the State, which was used to help estimate the quantity of timber products harvested in Minnesota. Aerial photos used in the Central Hardwood Unit survey were furnished by the Minnesota Department of Natural Resources and the usda Agricultural Stabilization and Conservation Service.

Succession-nothing in plant, community, or ecosystem ecology has been so elaborated by terminology, so much reviewed, and yet so much the center of controversy. In a general sense, every ecologist uses the concept in teaching and research, but no two ecologists seem to have a unified concept of the details of succession. The word was used by Thoreau to describe, from a naturalist's point of view, the general changes observed during the transition of an old field to a forest. As data accumulated, a lengthy taxonomy of succession developed around early twentieth century ecologists such as Cooper, Clements, and Gleason. Now, nearer the end of the century, and after much discussion concerning the nature of vegetation communities, where do ecologists stand with respect to knowledge of ecological succession? The intent of this book is not to rehash classic philosophies of succession that have emerged through the past several decades of study, but to provide a forum for ecologists to present their current research and present-day interpretation of data. To this end, we brought together a group of scientists currently studying terrestrial plant succession, who represent research experience in a broad spectrum of different ecosystem types. The results of that meeting led to this book, which presents to the reader a unique summary of contemporary research on forest succession.

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.

Japan’s traditional and fragile satoyama landscape system was developed over centuries of human life on mountainous island terrain in a monsoon climate. The carefully managed coppice woodlands on the hillsides, the villages strung along the base of the hills, and the carefully tended paddy fields of rural Japan made possible the sustainable interaction of nature and humans. Radical changes in the middle of the twentieth century led to the abandonment of satoyama landscapes which now are being rediscovered. There is a new realization that these woodlands still play a vital role in the management of the Japanese landscape and a new determination to manage them for the future. This multifaceted book explores the history, nature, biodiversity, current conservation measures, and future uses of satoyama. The information presented here will be of interest in all parts of the world where patterns of sustainable development are being sought.

This book is exclusively concerned with wood modification, although many of these processes are generic and can be applied to other lignocellulosic materials. There have been many rapid developments in wood modification over the past decade and, in particular, there has been considerable progress made in the commercialisation of technologies. Topics covered include: The use of timber in the 21st century Modifying the properties of wood Chemical modification of wood: Acetic Anhydride Modification and reaction with other chemicals Thermal modification of wood Surface modification Impregnation modification Commercialisation of wood modification Environmental consideration and future developments This is the first time that a book has covered all wood modification technologies in one text. Although the book covers the main research developments in wood modification, it also puts wood modification into context and additionally deals with aspects of commercialisation and environmental impact. This book is very timely, because wood modification is undergoing huge developments at the present time, driven in part by environmental concerns regarding the use of wood treated with certain preservatives. There has been considerable commercial interest shown in wood modification over the past decade, with products based upon thermal modification, and furfurylation now being actively being marketed. The next few years will see the commercialisation of acetylation and impregnation modification. This is a new industry, but one that has enormous potential. This book will prove useful to all those with an interest in wood modification including researchers, technologists and professionals working in wood science and timber engineering, wood preservation, and well as professionals in the paper and pulp industries, and those with an interest in the development of renewable materials.
