Book Description
This report uses data from a network of forest inventory plots sampled at two points in time, annual aerial insect and disease surveys, and specialized pest damage surveys to quantify the incidence and impact of insects, diseases, and other damaging agents on Oregon's forests. The number and volume of trees damaged or killed by various agents is summarized. Differences in the frequency and severity of damaging agents between various ownership categories and geographic regions of the state are investigated.

Book Description
This report highlights key findings from the most recent (2001-2005) data collected by the Pacific Northwest Forest Inventory and Analysis (PNW-FIA) Program across all ownerships in Oregon. We present basic resource information such as forest area, land use change, ownership, volume, biomass, and carbon sequestration; structure and function topics such as biodiversity, older forests, dead wood, and riparian forests; disturbance topics such as insects and diseases, fire, invasive plants, and air pollution; and information about the forest products industry in Oregon, including data on tree growth and mortality, removals for timber products, and nontimber forest products. The appendices describe inventory methods and design in detail and provide summary tables of data, with statistical error, for the suite of forest characteristics sampled.
