Book Description
In analysing the development and achievements of Polish forestry and forest industries over the last four decades, it is necessary to take into consideration the situation prevailing after the end of the Second World War, when these sectors of the national economy were starting their activities. First of all, it is necessary to consider the effects of the war such as: (a) the harvesting from the forests of the present Polish territory of 3 about 200 million m of merchantable wood, which is equal to the normal harvest over a l2-year period; (b) the destruction of over half the woodworking industrial potential. In consequence, the forested area inside the new Polish boundaries amounted 40 years ago only to 20.8 per cent of the whole area of the country. There has been a continuing process of increasing the forested area of the country (although at a diminishing rate). In 1986 the forest area amounted to 27.7 per cent of the land surface, that is to 8.7 million ha, an increase of over 2 million ha in 40 years. Intensive afforestation, performed regardless of the ownership category of the land by the State forest service, was aimed primarily at making good the losses in the forested area and the rational use of land not fit for agricultural purposes.

Book Description
Positive Impact Forestry is a primer for private woodland owners and their managers on managing their land and forests to protect both ecological and economic vitality. Moving beyond the concept of "low impact forestry," Thom McEvoy brings together the latest scientific understanding and insights to describe an approach to managing forests that meets the needs of landowners while at the same time maintaining the integrity of forest ecosystems. "Positive impact forestry" emphasizes forestry's potential to achieve sustainable benefits both now and into the future, with long-term investment superseding short-term gain, and the needs of families—especially future generations—exceeding those of individuals. Thom McEvoy offers a thorough discussion of silvicultural basics, synthesizing and explaining the current state of forestry science on topics such as forest soils, tree roots, form and function in trees, and the effects of different harvesting methods on trees, soil organisms, and sites. He also offers invaluable advice on financial, legal, and management issues, ranging from finding the right forestry professionals to managing for products other than timber to passing forest lands and management legacies on to future generations. Positive Impact Forestry helps readers understand the impacts of deliberate human activities on forests and offers viable strategies that provide benefits without damaging ecosystems. It speaks directly to private forest owners and their advisers and represents an innovative guide for anyone concerned with protecting forest ecosystems, timber production, land management, and the long-term health of forests. Named the "Best Forestry Book for 2004" by the National Woodlands Owners Association.

Book Description
Forests are in decline, and the threats these outposts of nature face—including deforestation, degradation, and fragmentation—are the result of human culture. Or are they? This volume calls these assumptions into question, revealing forests’ past, present, and future conditions to be the joint products of a host of natural and cultural forces. Moreover, in many cases the coalescence of these forces—from local ecologies to competing knowledge systems—has masked a significant contemporary trend of woodland resurgence, even in the forests of the tropics. Focusing on the history and current use of woodlands from India to the Amazon, The Social Lives of Forests attempts to build a coherent view of forests sited at the nexus of nature, culture, and development. With chapters covering the effects of human activities on succession patterns in now-protected Costa Rican forests; the intersection of gender and knowledge in African shea nut tree markets; and even the unexpectedly rich urban woodlands of Chicago, this book explores forests as places of significant human action, with complex institutions, ecologies, and economies that have transformed these landscapes in the past and continue to shape them today. From rain forests to timber farms, the face of forests—how we define, understand, and maintain them—is changing.

Book Description
This volume comprises fifteen papers exploring the consequences of applying modern time-series methods, particularly co-integrated time-series methods, for the analysis of forest economics problems. The methods represent the forefront of econometrics in this area, and the volume is the first of its kind. An introductory paper explains the econometrics of unit-root processes. Much of what follows in the other papers depends upon only a few of the ideas presented in the introduction. The volume includes tests of, e.g., the Law of One Price, land valuation models, demand and supply models, Granger-causality, and forecast models. The reader will learn a great deal about forest economies, particularly in Northern Europe, and about the practical use of modern time-series methods. The methods presented are applicable to other fields of economics. The volume is aimed at researchers in applied economics and as a supplement to (advanced) theoretical textbooks, mainly in Natural Resource Economics.

Book Description
Fundamental changes have occurred in all aspects of forestry over the last 50 years, including the underlying science, societal expectations of forests and their management, and the evolution of a globalized economy. This textbook is an effort to comprehensively integrate this new knowledge of forest ecosystems and human concerns and needs into a management philosophy that is applicable to the vast majority of global forest lands. Ecological forest management (EFM) is focused on policies and practices that maintain the integrity of forest ecosystems while achieving environmental, economic, and cultural goals of human societies. EFM uses natural ecological models as its basis contrasting it with modern production forestry, which is based on agronomic models and constrained by required return-on-investment. Sections of the book consider: 1) Basic concepts related to forest ecosystems and silviculture based on natural models; 2) Social and political foundations of forestry, including law, economics, and social acceptability; 3) Important current topics including wildfire, biological diversity, and climate change; and 4) Forest planning in an uncertain world from small privately-owned lands to large public ownerships. The book concludes with an overview of how EFM can contribute to resolving major 21st century issues in forestry, including sustaining forest dependent societies.

Book Description
Forests for the People tells one of the most extraordinary stories of environmental protection in our nation’s history: how a diverse coalition of citizens, organizations, and business and political leaders worked to create a system of national forests in the Eastern United States. It offers an insightful and wide-ranging look at the actions leading to the passage of the Weeks Act in 1911—landmark legislation that established a system of well-managed forests in the East, the South, and the Great Lakes region—along with case studies that consider some of the key challenges facing eastern forests today. The book begins by looking at destructive practices widely used by the timber industry in the late 1800s and early 1900s, including extensive clearcutting followed by forest fire that devastated entire landscapes. The authors explain how this led to the birth of a new conservation movement that began simultaneously in the Southern Appalachians and New England, and describe the subsequent protection of forests in New England (New Hampshire and the White Mountains); the Great Lakes region (Michigan, Wisconsin, and Minnesota), and the Southern Appalachians. Following this historical background, the authors offer eight case studies that examine critical issues facing the eastern national forests today, including timber harvesting, the use of fire, wilderness protection, endangered wildlife, oil shale drilling, invasive species, and development surrounding national park borders. Forests for the People is the only book to fully describe the history of the Weeks Act and the creation of the eastern national forests and to use case studies to illustrate current management issues facing these treasured landscapes. It is an important new work for anyone interested in the past or future of forests and forestry in the United States.

Book Description
From prehistory to the present, people have harvested Mississippi's trees, cultivated and altered the woodlands, and hunted forest wildlife. Native Americans, the first foresters, periodically burned the undergrowth to improve hunting and to clear land for farming. Mississippi Forests and Forestry tells the story of human interaction with Mississippi's woodlands. With forty black-and-white images and extensive documentation, this history debunks long-held myths, such as the notion of the first settlers encountering "virgin" forests. Drawing on primary materials, government documents, newspapers, interviews, contemporary accounts, and secondary works, historian James E. Fickle describes an ongoing commerce between people and place, from Native American maintenance of the woods, to white exploration and settlement, to early economic activities in Mississippi's forests, to present-day conservation and responsible use. Viewed over time, issues of conservation are rarely one-sided. Mississippi Forests and Forestry describes how the rise of "scientific" forestry coincided with the efforts of some early lumber companies and industrial foresters to operate responsibly in harvesting trees and providing for reforestation. Surprisingly, the rise of the pulp and paper industry made reforestation possible in many parts of the state. Mississippi Forests and Forestry is a history of individuals as well as industries. The book looks closely at the ways the lumber industry operated in the woods and mills and at the living and working conditions of people in the industries. It argues that the early industrial foresters, some lumber companies, and pulp and paper manufacturers practiced utilitarian conservation. By the late 1950s, they accomplished what some considered a miracle. Mississippi's forests had been restored. With the rise of environmentalism in the 1960s, popular ideas concerning the proper management and use of forests changed. Practices such as clear-cutting, single-age management, and manufacturing by chip mills became highly controversial. Looking ahead, Mississippi Forests and Forestry examines the issues that remain heated topics of conservation and use.
