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.

Includes a database of relevant studies reporting peak flow data across rain-, transient-, and snow-dominated hydrologic zones. Provides a quantitative comparison of changes in peak flow across both a range of flows and forest practices. Increases in peak flows generally diminish with decreasing intensity of percentage of watershed harvested and lengthening recurrence intervals of flow. Peak flow effects on channel morphology should be confined to stream reaches where channel gradients are less than 0.02 and streambeds are composed of gravel and finer material. Managers should evaluate the potential risk of peak flow increases based on factors such as presence of roads, specific mgmt. treatments employed, and watershed drainage efficiency.
