This study analysed the role of defensible space by mapping and measuring a suite of pre-fire variables for 1000 destroyed and 1000 surviving structures for all fires where homes burned from 2001 to 2010 in San Diego County, CA, USA. Structures were more likely to survive a fire with defensible space immediately adjacent to them. The most effective treatment distance varied between 5 and 20 m (16–58 ft) from the structure, but distances larger than 30 m (100 ft) did not provide additional protection, even for structures located on steep slopes. The most effective actions were reducing woody cover up to 40% immediately adjacent to structures and ensuring that vegetation does not overhang or touch the structure.

This study summarizes data from extensive monitoring (2003-12) of sage-grouse populations within the Bi-State DPS. Data regarding lek attendance, movement, and survival of sage-grouse across multiple life stages were documented. A hierarchical integrated population modeling (IPM) approach was used to derive demographic parameters, which allows for the integration of multiple data sources to inform population growth rates and population vital rates.
View brief.
This brief highlights a study following fire in Utah’s Rush Valley, where researchers found that fire killed biological soil crust pretty thoroughly, which wasn’t a surprise. However, following the fire cyanobacteria, the helpful and essential ingredient in biocrusts, did not return soon after fire, but Firmicutes, another tenacious and aggressive bacteria, did move in.

This research brief highlights a study investigating whether on not deer mice could help combat the invasive weeds infiltrating desert landscapes after fire.
View report.
This is the final national report of the three-phased National Cohesive Wildland Fire Management Strategy development. The National Strategy includes a set of guidelines intended to provide basic direction when planning activities. Broadly defined to address national challenges, these guidelines can be tailored to meet local and regional needs
View report.
This report, developed by the Western Association of Fish and Wildlife Agencies (WAFWA), Wildfire and Invasive Species Initiative Working Group (Working Group), summarizes the current state of Fire Operations and Fuels management functions in big sagebrush communities. The intent of this report is to illustrate the type and responsiveness of efforts being made. Finally, the report concludes by presenting future options and a series of recommendations that may inform future policy and allocation decisions.

Results of this case study suggest that if applications and conditions of this study can be mimicked, livestock producers and natural resource managers can likely use fall prescribed fire in the mesic sagebrush steppe to affect cattle resource-use patterns for 5 years postfire.

In this study, researchers compiled landscape-scale evidence of historical fire severity patterns in the ponderosa pine and mixed-conifer forests from published literature sources and stand ages available from the Forest Inventory and Analysis program in the USA. The consensus from this evidence is that the traditional reference conditions of low-severity fire regimes are inaccurate for most forests of western North America. Instead, most forests appear to have been characterized by mixed-severity fire that included ecologically significant amounts of weather-driven, high-severity fire.
