A comprehensive guide to effective hardwood forest management Extending 235,000 square miles from New York to Georgia and fromVirginia to Missouri, the Central Hardwoods Region harbors the mostextensive concentration of deciduous hardwoods in the world. Asharvests in the Pacific Northwest decline and timber prices rise,the maturing stands of mixed species in this central U.S. regionare a rich and valuable resource that is increasingly vulnerable toexploitation. This timely book examines all of the key ecological,social, and economic management considerations essential to utilizeand sustain these vital woodlands effectively. First, it develops the background necessary to understand whatmakes the hardwood eco-system function, with a thorough examinationof the physiography, geology, soils, and climate of the region anda historical overview of its evolution and development frompre-European settlement to the present. Then, species by species,the book details the silvical characteristics of 34 important treespecies. Next, it offers expert recommendations for effectiveforest treatment and management, from specific concerns such astimber production, pollution, and financial planning to broaderissues, including the role of the natural resource manager and thebiological potential of the entire region. Generously supplemented with graphs and photos, Ecology andManagement of Central Hardwood Forests is important reading forforesters, natural resource managers, regional planners,environmental scientists, governmental officials--everyone with astake in the future of this critical living resource.

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.

S2After more than 20 years of USDA Forest Service research on the growth and yield of hardwoods in the Central States, we can now confidently make recommendations for the management and culture of upland hardwood stands that are predominantly oak. In this paper I will deal with the first 50 years of stand development under one logical thinning policy. S3.
