Available in PDF, EPUB and Kindle. Book excerpt: S2The root rot caused by the fungus Fomes annosus is a serious threat to coniferous plantations throughout the North Temperate Zone. It is especially prevalent in plantations that have been thinned; and it commonly spreads through the roots from diseased trees to healthy news. In 1962-67 we conducted a series of experiments to provide preliminary information for testing the hypothesis; that a continuous band or zone of roots rendered unsuitable for invasion by F. annosus will prevent the underground spread of this fungus from diseased to healthy trees.S3.

This book was released on 1968 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2In a study carried out on the George Washington National Forest, 72 of the existing 143 site-stand condition classes were designates as candidates for timber-stand-improvement or conversion projects. But which projects are worth undertaking, and which should receive priority? These are decisions that confront program administrators and forest managers alike. To help them in this we have made investment analyses of the 19 most prevalent (modal) project classes, which together encompass almost 124 thousand acres of this Forest in Virginia and West Virginia. By providing a basis for rating and comparing opportunities, these appraisals suggest what kinds of projects to favor in planning an efficient program for stand improvement and stand conversion.S3.
