Excerpt from Reducing Mortality in Old-Growth Northern Hardwoods Through Partial Cutting A third source is the 472 permanent inventory plots which were installed during 19u0, 19ul, and l9u2 on the enlarged experimental forest as it was being placed under management. These were fifth-acre plots, on which all trees were diagrammed on map sheets. The area involved was 9m acres. About 70 percent of these plots were on areas which had been given a light improvement cut; the majority of the others were on areas uncut except for salvage of dead trees. These records are available for an average period of a little over 6 years. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

"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.
