Book Description
"The even-aged hardwood forest, with a poorly balanced distribution of age-classes, can cause perplexing problems during the first rotation. What is the best cutting strategy to follow? By using linear programming, we developed some cutting strategies that maximize board-foot production and produce a balanced age distribution by the end of the first rotation. We developed the strategies for four hypothetical northern hardwood forests with different unbalanced age distributions. Although these strategies may be used for forest lands with conditions similar to those assumed in this study, we urge that the linear programming techniques described in this paper be used to develop strategies tailored to particular forests and to particular management objectives.

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
S2Unfortunately there have been few attempts to apply complete clearcutting to northern hardwood forests. One notable exception is a 22-acre tract on the Bartlett Experimental Forest in New Hampshire. Jensen (2) has reported on the regeneration present 5 years after clearcutting on that tract. The regeneration there has now developed into a 30-year-old stand; and this stand provides a unique opportunity to examine the case history of a northern hardwood stand resulting from complete clearcutting.

Book Description
Habitat characteristics were quantified in an empirically balanced uneven-aged northern hardwood stand in central New York. Canopy structure, wildlife trees, downed woody material, low cover, and richness and abundance of understory vegetation were assessed. This study provides quantifiable evidence of the diversity of habitat characteristics associated with a balanced stand structure and uniform spatial arrangement of different sized trees in uneven-aged northern hardwood stands.--Publisher description.
