Field Guide to the Common Diseases and Insect Pests of Oregon and Washington Conifers is a useful aid for forestry practitioners and conifer forest landowners in the Pacific Northwest. This handy guide is designed for use in field conditions and describes more than 100 biotic and abiotic agents, emphasizing key identification traits and illustrative photos. It includes general overviews of important agent groups, including bark beetles, root diseases, stem decays, canker diseases and rusts, dwarf mistletoes, foliar pathogens, and defoliating insects. Biotic agents are organized according to their primary association with one of three major tree parts: roots, stem and branches, or foliage. Abiotic and noninfectious diseases are listed in a separate section. Individual agent descriptions are provided in a two-page format with descriptive text facing a page containing multiple color images and a "key characters" box. Each description provides the insect or pathogen common and scientific names, hosts, and information on distribution and damage, identification, agents producing similar symptoms and signs, and severity. Also included are a color-coded quick tab feature at the front of the book, diagnosis tips, identification keys, drawings of bark beetle gallery patterns, agent comparison tables, references, glossary, and an index with embedded color-highlighted host-pest indexes for easy reference.
