A historical record of Pacific Northwest (defined here as west of the Cascade Mountains in Washington and Oregon) heat waves is identified using the U.S. Historical Climate Network, version 2, daily data (1901–2009).
Prescribed burning is an effective method to reduce hazardous fuels and restore ecological conditions across a variety of ecosystems. Twenty-one states have laws or policies that direct state agencies to oversee formal training programs to certify individuals in safe burning techniques. Fifteen of these states have active certified prescribed burn manager programs (CPBM).
The Columbia Basin Natural Wildlife Refuge (CNWR) had been periodically grazed until the Refuge was established in 1944. Cheatgrass became a prominent plant in the area. In 1986 a fire occurred near the study area. The area was reseeded with Elymus wawawaiensis (Snake River Wheatgrass, Secar cultivar). This grass has established reducing cheatgrass cover to very low levels.
The USGS Wildland Fire Science Strategic Plan (hereafter, Strategic Plan) was developed by USGS fire scientists and executive leadership, and was informed by discussions with external stakeholders.
In parts of central Oregon, coarse-textured pumice substrates limit forest composition to low-density lodgepole pine (Pinus contorta Douglas ex Loudon var. latifolia Engelm. ex S. Watson) with scattered ponderosa pine (Pinus ponderosa Lawson & C. Lawson) and a shrub understory dominated by antelope bitterbrush (Purshia tridentata (Pursh) DC.).
This sourcebook provides answers from the field— strategies and tools that some collaborative resource management groups have used to systematically evaluate their work and adapt plans and management actions based on what they have learned.

This report focuses on a critical aspect of working towards community fire adaptation: analyzing effective land use policy and regulatory solutions in the wildland-urban interface (WUI). The WUI is any area where the built and natural environments create a set of conditions that allow for the ignition and continued spread of wildfire.
This report reviews the growing literature on the concept of agency-citizen interactions after large wildfires. Because large wildfires have historically occurred at irregular intervals, research from related fields has been reviewed where appropriate.
On steep slopes between 30-45 degrees, loose soil is stored behind plant “dams.” After a fire, > 75% of stored sediment is rapidly released to the channel system by dry ravel (the rolling, bouncing, and sliding of individual particles). The postfire hazard from stored sediment can be calculated at the catchment scale if the size and distribution of vegetation cover are known.
