Book Description
Excerpt from Field Guide to the Common Diseases and Insect Pests of Oregon and Washington Conifers Phytophagous plant - eating) insects and tree pathogens (organisms that cause diseases of trees) are important components of coniferous forests in Washington and Oregon. They are most commonly known for causing individual tree-level impacts, such as growth reduction, breakage, deformity, and mortality. However, insects and pathogens do have significant effects on forest structure, species composition, and succession at stand and landscape levels. Insects and pathogens can influence the development and quality of wildlife habitat, watershed values, visual character, nutrient cycling, commodity production, and human safety. This field guide has been prepared to provide forest resource managers with a basic tool for quick field identification of diseases and insects that are commonly found affecting conifers in the Pacific Northwest. It does not attempt to describe or list all insects and pathogens found affecting coniferous trees, only those most commonly encountered. This field guide should be used in combination with other resources such as the books Western Forest Insects (furniss and Carolin 1977) and Diseases of Pacific Coast Conifers (scharpf Written descriptions, identification keys, comparative tables, photographs, and line drawings are used to illustrate and emphasize key characteristics that will help the user identify the common insects and pathogens during field reconnaissance.

Excerpt from Diseases of Coniferous Trees Polyporus schweinitzii Fr. Ranks next in importance to Trametes pini in the natural forests. It commonly attacks the heartr wood of the base or butts of the trunk and of the roots of coniferous trees, especially the Douglas firs. The rot rarely extends farther up the trunk than the first saw log. The fungus spreads from diseas ed trees to healthy ones underground, where larger roots come in con tact with each other. Where this takes place it is common to find groups of trees affected with the fungus, and sometimes an entire group of Douglas firs are killed outright, In.most instances, how ever, the trees weakened by the fungus are either uprooted or broken off by the winds before death.

Book Description
Excerpt from Some Diseases of New England Conifers: A Preliminary Report Very little attention has been paid to the study of diseases of forest trees in the United States up to this time, and the reasons are Obvious enough. Up to within a few years the supply Of standing timber of all kinds has been so large that a few diseased trees, more or less, scat tered over wide areas were Of little account. The lumberman cut down the sound trees and paid no attention to such as he recognized to be of inferior value. The situation has changed within the last decades, and a wide-felt demand has arisen among all classes of people for a more economical and rational treatment of the existing forest lands, and for reestablishing forests on denuded areas. In the primeval forest the trees diseased because of fungous or insect attack were ignored. They were few in comparison with sound trees, and the price of a single tree was very low. At the present time, with a marked appreciation in the value Of timber, the agencies which injure trees for timber are of more immediate interest to the owners of woodlands. At this time the extent to which insects and fungi destroy trees can only be guessed at. Their work of destruction goes on silently here and there in the forest, and does not attract the attention of the casual Observer as do careless lumbering or forest fires. If the dead and dying trees in a forest could be collected, they would represent a con siderable percentage of the total forest. Forest fires are already not so common as they used to be, and the lumberman of today is beginning to understand that more can be realized from a given forest tract by rational treatment than by indiscriminate cutting. Insects and fungi, and other harmful agencies Of less importance, are being studied with the aim of arriving at a more complete understanding Of their manner of working.
