View the guide.
The primary purpose of this guide is to serve as a tool for communicating potential particulate matter (PM2.5) levels during wildfire events using visual representation. Examples of visibility impairment under various levels of smoke concentration and humidity have been modeled using the WinHaze program.

These abstracts of recent papers on range management in the West were prepared by Charlie Clements, Rangeland Scientist, USDA Agricultural Research Service, Reno, NV.
View synthesis.
The Fire Effects Information System (FEIS) just completed and published online a synthesis of the biology, ecology, and fire relationships for the greater sage-grouse and Gunnison sage-grouse.

This research brief reports that applying salvaged biocrust material to severely disturbed soil rapidly reestablished favorable biocrust characteristics and stabilized soil more than doing nothing. This is likely a useful restoration strategy when unavoidable soil disturbances are planned and there are opportunities to salvage material.

This brief synthesizes best-management practices for reducing non-native grasses while increasing native species and desirable features in desert tortoise habitats.

This study was designed to contribute to the limited literature describing the benefits of better integrating indigenous knowledge (IK) with other sources of knowledge in making adaptive-management decisions. Specifically, we advocate the integration of traditional phenological knowledge (TPK), a subset of IK, and highlight opportunities for this knowledge to support policy and practice of adaptive management with reference to policy and practice of adapting to uncharacteristic fire regimes and climate change in the western United States.

This study explored recovery of Wyoming big sagebrush (Artemisia tridentata ssp.wyomingensis) and basin big sagebrush (A. tridentata ssp. tridentata) communities following fire in the northern Columbia Basin (Washington, USA). Density of large–mature big sagebrush plants and percentage cover of big sagebrush were higher with time since fire and in plots with more precipitation during the winter immediately following fire, but were lower when precipitation the next winter was higher than average, especially on soils with higher available water supply, and with greater post-fire mortality of mature big sagebrush plants. Bunchgrass cover 5 to 28 years after fire was predicted to be lower with higher cover of both shrubs and non-native herbaceous species, and only slightly higher with time. Post-fire recovery of big sagebrush in the northern Columbia Basin is a slow process that may require several decades on average, but faster recovery rates may occur under specific site and climate conditions.

This report examined multiple climate change effects on cattle production for U.S. rangelands to estimate relative change and identify sources of vulnerability among seven regions. Climate change effects to 2100 projected (1) an increase in forage quantity in northerly regions, (2) a move toward grassier vegetation types overall but with considerable spatial heterogeneity, (3) a rapid increase in the number of heat-stress days across all regions, and (4) higher forage variability for most regions.

This research brief is based on several studies that can inform decision making by fire managers. Knowing that fire occurrence, size, and severity are limited by recent wildfires should provide greater flexibility and confidence in managing fire incidents and managing for resource benefit. Specifically, the findings from this study can be used by fire managers to help predict whether a previous fire will act as a fuel treatment based on fire age, forest type, and expected weather.
