Book excerpt: Today, forest health and the management of threats towards it are attracting more and more attention on a global scale. This book covers the most recent advances in the management of forest diseases, including the epidemiology and infection biology of forest pathogens, and forest protection based on integrated pest and disease management approaches. A comprehensive range of diseases caused by viruses, bacteria, fungi and other organisms are discussed in detail, making this book essential reading for forest managers and extension specialists. Written by recognized authorities in the subject of forest health, this book also provides a wealth of information useful for researchers and lecturers of forest pathology and ecology.

This book was released on 1991 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: The COWFISH model, developed and applied in selected Montana streams, was tested on 14 streams in Idaho, Nevada, and Utah, where it proved to have little value for predicting numbers of trout in watersheds grazed by livestock. The model holds promise for estimating the health of stream channels and riparian complexes.

Available in PDF, EPUB and Kindle. Book excerpt: Mountain hemlock forests in the Oregon Cascades exhibit wave-form dieback resulting from infection by laminated root rot (Phellinus weirii). Although Phellinus remains viable in dead roots after the wave of dieback passes, many regenerating mountain hemlock forests do not become immediately reinfected. We measured at least a doubling of nitrogen availability in the dieback and regrowth zones, and thought that this increased availability could improve tree resistance to the fungus. To test this hypothesis, we grew small mountain hemlocks under nutrient and light limitations in a growth-room, and then inoculated with the fungus. Trees growing without added nutrients had significantly greater foliage damage and mortality after Phellinus inoculation than did trees growing with nutrients. Shading significantly increased susceptibility whether or not nutrients were added. We believe that increased nitrogen availability and possibly increased light levels after dieback in the field act similarly to increase resistance and prevent reinfection of the regrowing stands. Foliage damage and susceptibilty to infection were related to pool sizes of total nitrogen, phosphorus, and non-structural carbohydrates. Plants with very low nitrogen reserves (
