View field guide.
This field guide is designed to help agricultural producers, land managers, homeowners, recreationists, and others to identify the noxious weeds of Nevada. All weeds listed by Nevada state law (as of 2010) are included, each with a brief description, color photographs, and recommendations for control.

This paper provides a decision framework that integrates fire regime components, plant growth form, and survival attributes to predict how plants will respond to fires and how fires can be prescribed to enhance the likelihood of obtaining desired plant responses.

Results of this study indicate that native grasses more readily establish in synchrony with crested wheatgrass than native shrubs, but once established, native shrubs are more likely to coexist and persist with crested wheatgrass because of high niche differentiation (e.g., not limited by the same resource). Results also suggest that developing strategies to minimize interference from crested wheatgrass seedlings emerging from seed banks will enhance the establishment of native species seeded into crested wheatgrass–dominated communities.

The objective of this study was to determine the feasibility of restoring native plant species to crested wheatgrass-dominated rangeland by testing five suppression treatments. Results suggested that suppression treatments were not effective and therefore did not improve restoration of native species in crested wheatgrass stands. Native species establishment may require subsequent management to favor persistence of native species and retard crested wheatgrass.

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.

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 predicts moderately more frequent drought for the Great Basin with climate change.
View report.
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.
View synthesis.
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.

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.
