Synopsis

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.
