Synthesis / Tech Report
This chapter reviews some of the conceptual and technological advancements and provide examples of how they have influenced rangeland monitoring. It then discuss implications of these developments for rangeland management and highlight what are seen as challenges and opportunities for implementing effective rangeland monitoring. It concludes with a vision for how monitoring can contribute to rangeland information needs in the future.

This report examines federal officials’ and stakeholders’ views on (1) factors that affect federal-nonfederal collaboration aimed at reducing wildland fire risk to communities and (2) actions that could improve their ability to reduce risk to communities.

This synthesis updated the Conservation Effects Assessment Project (CEAP) review and broadened the discussion of prescribed fire as a global management practice. It reviews and summarizes prescribed fire literature available through Web of Science using search terms in the title. The majority of literature (40%) evaluated plant responses to fire with fire behavior and management (29%), wildlife and arthropods (12%), soils (11%), and air quality (4%) evaluated less frequently. Generally, fire effects on plants are neutral to positive and the majority of negative responses lasted less than 2 years. Similarly, soil responses were recovered within 2 yr after burning. However, most studies did not report how long treatments were in place (62%) or the size of experimental units (52%).
View guide.
This guide is designed to provide direction on the critique and modification of LANDFIRE geospatial data products for local applications. It is not so much a “cookbook” or “how-to” guide, as the specifics vary greatly by data product, intended use, scale, and location. Rather, it presents primary considerations for using and modifying the data for use in local applications and provide examples and demonstrations of available tools and methods for completing common critique and modification tasks.

This short synthesis highlights findings of the national Fire and Fire Surrogates Study, which conducted an integrated network of experiments at 13 sites across the United States, many of which took place on National Forest lands. Results suggest that more species increased in number than decreased. For example, researchers reported that populations of western bluebirds (Sialia mexicana) increased following prescribed fire; whereas mountain chickadees (Poecile gambeli) decreased in response to thinning treatments. The positive and negative responses of deer mice (Peromyscus maniculatus), gray-collared chipmunks (Tamias cinereicollis) and least chipmunks (T. minimus) varied among the sites; but the overall biomass of small mammals increased in response to the fire treatments. Researchers also found that small mammals’ responses were related to fire uniformity: the more heterogeneous the post-fire landscape, the greater the proportion of positive responses.

This report evaluated how changes in climate in the United States would lead to changes by the middle and the end of the current century in annual spending to suppress wildfires on USDA Forest Service (FS) and Department of the Interior (DOI) managed lands.
To do this, researchers developed a two-stage model. In the first stage, we analyzed the historical relationships between area burned on FS and DOI lands and maximum daily temperatures and other variables. In the second stage, we analyzed historical relationships between area burned and suppression spending.
Then, using projections of climate obtained from general circulation models, we projected area burned, and used this projection in our second stage model to project spending on suppression. All spending projections were done with constant 2014 dollars. We made projections for mid-century (2041-2059) and late-century (2081-2099). Uncertainty in the area burned and suppression spending was quantified using Monte Carlo simulation methods, incorporating parametric uncertainty from the two stage models and climate uncertainty from the alternative climate projections.
Results show that median area burned on DOI lands is projected to increase, compared to the amount observed between 1995 and 2013, by 99% by mid-century and by 189% by late-century. For FS lands, the increases are projected to be 123% by mid-century and 221%, respectively. Given such changes in area burned, DOI spending is projected to increase by 45% by mid-century and by 72% by late-century. For the FS, annual spending is projected to rise by 117% and 192%, respectively. Such changes would entail an increase in dollars spent in total across both agencies from a historical average of $1.33 billion to a projected $2.63 billion in mid-century and $3.47 billion by late-century.

This report is a synthesis of current knowledge on the effects of wildfire and fuels treatments in riparian areas of the interior western United States, and includes the following: (1) a literature review of fire effects on riparian and aquatic characteristics and functions, provided as background for considering the need and potential impacts of fuel treatments; (2) a review of the potential effects of prescribed fire and mechanical treatments on riparian and aquatic resources and biota; (3) results of an online survey of resource managers, summarizing information about proposed and completed fuel reduction projects in riparian areas and wetlands in the interior west; (4) suggestions for pre- and post project-level monitoring for riparian fuels projects; and (5) a presentation of case studies, describing riparian fuel treatments with different objectives and methods.

This technical manual provides regional accounts of historical and current uses of fire, and then discusses fire effects on wildlife and the challenges of using prescribed fire in each system.

The Integrated Rangeland Fire Management Strategy outlined the need for coordinated, science-based adaptive management to achieve long-term protection, conservation, and restoration of the sagebrush (Artemisia spp.) ecosystem. A key component of this management approach is the identification of knowledge gaps that limit implementation of effective strategies to meet current management challenges. The tasks and actions identified in the Strategy address several broad topics related to management of the sagebrush ecosystem. This science plan is organized around these topics and specifically focuses on fire, invasive plant species and their effects on altering fire regimes, restoration, sagebrush and greater sage-grouse (Centrocercus urophasianus), and climate and weather.
