Book Description
The forests of the Southern United States were little influenced by man until the mid-19th century when they become the focus of an early export lumber business. Longleaf pine (Pinus palustris Mill.) was the choice species due to its straightness and self pruning that produced high quality lumber and high resin content that limited decay and insect attack. The South's original longleaf pine dominated forest is estimated at 90 million acres. As the supply of virgin stands began to decline in the Carolinas around 1860, harvesting gradually moved south and west and by the early 1900s was concentrated in the West Gulf Region. The introduction of railroad logging increased the efficiency to the point that insufficient long leaf trees remained uncut to provide for regeneration.

Book Description
Forests are major components of the earth's natural resources and they are increasingly critical to the welfare of the U.S. economy, environment, and population. Desires to improve forest management and productivity, preserve biodiversity, maintain ecologic integrity, and provide societal services, such as recreation and tourism, necessitate a strong forestry-research base. Given the clear importance of forestry research in sustaining forests for the future, the U.S. Department of Agriculture (USDA) Forest Service asked the Board on Agriculture and Natural Resources of the National Academies to undertake a study of the nation's capacity in forestry research. The Committee on National Capacity in Forestry Research was appointed to carry out the study, which was conducted to review the current expertise and status of forestry research and to examine the approaches of natural resources education and forestry-research organizations to meet future needs.

Book Description
"Southern forests provide innumerable benefits. Forest scientists, managers, owners, and users have in common the desire to improve the condition of these forests and the ecosystems they support. A first step is to understand the contributions science has made and continues to make to the care and management of forests. This book represents a celebration of past accomplishments, summarizes the current state of knowledge, and creates a vision for the future of southern forestry research and management. Chapters are organized into seven sections: "Looking Back," "Productivity," "Forest Health," "Water and Soils," "Socioeconomic," "Biodiversity," and "Climate Change." Each section is preceded by a brief introductory chapter. Authors were encouraged to focus on the most important aspects of their topics; citations are included to guide readers to further information."

Book Description
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.

Book Description
USDA Forest Service Experimental Forests and Ranges (EFRs) are scientific treasures, providing secure, protected research sites where complex and diverse ecological processes are studied over the long term. This book offers several examples of the dynamic interactions among questions of public concern or policy, EFR research, and natural resource management practices and policies. Often, trends observed – or expected -- in the early years of a research program are contradicted or confounded as the research record extends over decades. The EFRs are among the few areas in the US where such long-term research has been carried out by teams of scientists. Changes in society’s needs and values can also redirect research programs. Each chapter of this book reflects the interplay between the ecological results that emerge from a long-term research project and the social forces that influence questions asked and resources invested in ecological research. While these stories include summaries and syntheses of traditional research results, they offer a distinctly new perspective, a larger and more complete picture than that provided by a more typical 5-year study. They also provide examples of long-term research on EFRs that have provided answers for questions not even imagined at the time the study was installed.

Book Description
During the second half of the twentieth century, the forest industry removed more than 300 billion cubic feet of timber from southern forests. Yet at the same time, partnerships between public and private entities improved the inventory, health, and productivity of this vast and resilient resource. A comprehensive and multilayered history, Forestry in the U.S. South explores the remarkable commercial and environmental gains made possible through the collaboration of industry, universities, and other agencies. This authoritative assessment starts by discussing the motives and practices of early lumber companies, which, having exhausted the forests of the Northeast by the turn of the twentieth century, aggressively began to harvest the virgin pine of the South, with production peaking by 1909. By mid-century, however, industrial forestry had its own profit incentive to replenish harvested timber. This set the stage for a unique alliance between public and private sectors, which conducted cooperative research on tree improvement, fertilization, seedling production, and other practices germane to sustainable forest management. Incomparable in scope, Forestry in the U.S. South spotlights the people and organizations responsible for empowering individual forest owners across the region, tripling the production of pine stands, and bolstering the livelihoods of thousands of men and women across the South. -- from back cover.
