View brief.
This research brief discusses the effects of fire and invasive species on biological, chemical, and physical properties of desert soils. Although soil may recover from the impacts of fire during succession, these changes are permanent under persistent invasive species. The most severe effects of fire occur under high temperatures with high fuel buildup and soil moisture that conducts heat downward.

This synthesis addresses seven major conservation practices and two crosscutting issues: prescribed grazing, prescribed burning, brush management, range planting, riparian herbaceous cover, upland wildlife habitat management, herbaceous weed control, landscape analysis, socioeconomics and ecosystem services.

This synthesis chapter presents an assessment of the conservation effects of rangeland planting practices – both the assessment of the direct benefits of specific planting techniques recommended in the range planting standard, and assessment of specific conservation effects of alternative vegetation states.

Three models were evaluated in this study: CALPUFF, DAYSMOKE and CMAQ during different prescribed burn and wildfire episodes occurring throughout the southeastern US. Results suggested that CALPUFF could not be determined to be a suitable model for simulating the air quality impacts of fires. Model evaluation indicated that DAYSMOKE can be turned into a reliable a short‐range smoke‐impact prediction tool for land managers. On a regional scale, PM2.5 impacts of prescribed burns and wildfires are best predicted by air quality models such as CMAQ.

This synthesis includes 9 chapters covering: the current status of climate change science; the importance of fire regimes for understanding climate change impacts; the interrelationships among ecosystems, climate and fuels; the importance of understanding variability, change, scale and pattern for interpreting climate-fire interaction; fire history and climate change from an ecosystem perspective; scientific progress we can expect in the upcoming decade; some recommendations for managers for using fire history to inform their decision making under 21st Century climate change, and concluding thoughts.

In this report 38 federal, state, university, and nongovernmental experts collaborated to produce new scientific information about greater sage-grouse populations, sagebrush habitats, and relationships among sage-grouse, sagebrush habitats, and land use.

This report provides managers with the current state of knowledge regarding the effectiveness of fuel treatments for mitigating severe wildfire effects. A literature review examines the effectiveness of fuel treatments that had been previously applied and were subsequently burned through by wildfire in forests and rangelands. A case study focuses on WUI fuel treatments that were burned in the 2007 East Zone and Cascade megafires in central Idaho. Both the literature review and case study results support a manager consensus that forest thinning followed by some form of slash removal is most effective for reducing subsequent wildfire severity.

This study compared mechanical and chemical treatments to control crested wheatgrass and found that effective control can require secondary treatments to reduce the seed bank and open stands to dominance by seeded native species. Manipulation of crested wheatgrass stands to restore native species carries the risk of weed invasion if secondary treatments effectively control the wheatgrass and native species have limited survival due to drought.

This paper provides a historical perspective on fire in the Pacific Northwest. A warmer climate could bring more fire to the westside of the Cascade Range where summers are typically dry and will probably become drier. We can also expect longer fire seasons. The biggest concern for the future will be an increase in extreme weather events, which can lead to conditions that produce large and rapidly spreading wildfire.
