DOWNLOAD EBOOKFinancial maturity, diameter-limit (FMDL) selection was proposed more than three decades ago as a replacement for diameter-limit cutting. FMDL incorporates financial maturity guidelines for individual trees, high-priority removal of poor-quality trees, and guidelines for residual basal area. We provide the first long-term assessment of this practice after more than three decades of implementation. FMDL selection is evaluated in terms periodic yield of merchantable board feet, residual basal area, butt-log quality, and species composition. Recommendations for lowering the minimum residual basal area are presented. Management implications regarding controlling species composition are discussed.

DOWNLOAD EBOOKUSDA 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.
