This report found that records across the western US now show declines, of which 33% are significant (vs. 5% expected by chance) and 2% are significant and positive (vs. 5% expected by chance). Declining trends are observed across all months, states, and climates, but are largest in spring, in the Pacific states, and in locations with mild winter climate.

This study found that cross-validated results generally indicate a higher occurrence of smaller fires when months preceding fire season are wet, while larger fires are more frequent when soils are dry. This is consistent with the concept of increased fuel accumulation under wet conditions in the pre-season. These results demonstrate the fundamental strength of the relationship between soil moisture and fire activity at long lead-times and are indicative of that relationship’s utility for the future development of national-scale predictive capability.

The 2017 Fire Narrative and Timeline tells the story of successes and challenges, and also addresses emerging technology and science, such as Quantitative Risk Assessment, Risk Management Assistance Teams, and using Unmanned Aircraft Systems (drones) for infrared and reconnaissance flights.

This report found that treating low infestations across all three levels of forage production yields a financial gain, ranging from 21 cents to $4.94 per acre. However, treating highly infested areas showed a financial loss of $3.76 to $5.43 per acre, despite the level of forage production. Moderate infestations showed a financial gain with treatment only on sites producing 1,000 or 1,500 pounds per acre of forage.

Cheatgrass is now found in at least 49 states, although it’s mainly a problem in the semi-arid Great Basin — which stretches across portions of Utah, Nevada, Idaho, Oregon, and California — since its adapted to thrive in areas with wet winters and hot, dry summers. People are now used to seeing cheatgrass-dominated landscapes, but it’s not what we should see.

Collaborations and partnerships are increasingly recognized as essential for effective natural resource conservation. In fact, the collaborative partnerships that developed from 2010 to 2015 have been recognized as a key reason why the greater sage-grouse was kept off the federal endangered species list. Whether partnerships between federal and state agencies with private landowners, restoration projects coordinated between non-profit groups and land management agencies, or the thousands of hours negotiating state sage-grouse conservation plans, the collaborative efforts across the West were – and still are – unprecedented.

This report is intended to provide an initial assessment of both the potential effectiveness of fuel breaks and their ecological costs and benefits. To provide this assessment, the report examined prior studies on fuel breaks and other scientific evidence to address three crucial questions:
- How effective are fuel breaks in reducing or slowing the spread of wildfire in arid and semi-arid shrubland ecosystems?
- How do fuel breaks affect sagebrush plant communities?
- What are the effects of fuel breaks on the greater sage-grouse, other sagebrush obligates, and sagebrush-associated wildlife species?
It also provides an overview of recent federal policies and management directives aimed at protecting remaining sagebrush and greater sage-grouse habitat; describe the fuel conditions, fire behavior, and fire trends in the Great Basin; and suggest how scientific inquiry and management actions can improve our understanding of fuel breaks and their effects in sagebrush landscapes.
The greater sage-grouse (hereafter GRSG) has been a focus of scientific investigation and management action for the past two decades. The 2015 U.S. Fish and Wildlife Service listing determination of “not warranted” was in part due to a large-scale collaborative effort to develop strategies to conserve GRSG populations and their habitat and to reduce threats to both. New scientific information augments existing knowledge and can help inform updates or modifications to existing plans for managing GRSG and sagebrush ecosystems. However, the sheer number of scientific publications can be a challenge for managers tasked with evaluating and determining the need for potential updates to existing planning documents. To assist in this process, the U.S. Geological Survey (USGS) has reviewed and summarized the scientific literature published since January 1, 2015.
To identify articles and reports published about GRSG, we first conducted a structured search of three reference databases (Web of Science, Scopus, and Google Scholar) using the search term “greater sage-grouse.” We refined the initial list of products by (1) removing duplicates, (2) excluding products that were not published as research or scientific review articles in peer-reviewed journals or as formal government technical reports, and (3) retaining only those products for which GRSG or their habitat was a research focus.
In October 2017, after a review of the 2015 Federal plans relative to State sage-grouse plans, in accordance with Secretarial Order 3353, the BLM issued a notice of intent to consider whether to amend some, all, or none of the 2015 land use plans. At that time, the BLM requested the USGS to inform this effort through the development of an annotated bibliography of sage-grouse science published since January 2015 and a report that synthesized and outlined the potential management implications of this new science. Development of the annotated bibliography resulted in the identification and summarization of 169 peer-reviewed scientific publications and reports. The USGS then convened an interagency team (hereafter referred to as the “team”) to develop this report that focuses on the primary topics of importance to the ongoing management of sage-grouse and their habitats.
The team developed this report in a three-step process. First, the team identified six primary topic areas for discussion based on the members’ collective knowledge regarding sage-grouse, their habitats, and threats to either or both. Second, the team reviewed all the material in the Annotated Bibliography of Scientific Research on Greater Sage-Grouse Published since January 2015 to identify the science that addressed the topics. Third, team members discussed the science related to each topic, evaluated the consistency of the science with existing knowledge before 2015, and summarized the potential management implications of this science. The six primary topics identified by the team were:
- Multiscale habitat suitability and mapping tools
- Discrete anthropogenic activities
- Diffuse activities
- Fire and invasive species
- Restoration effectiveness
- Population estimation and genetics

This study evaluated how targeted grazing treatments interacted with seed rate, spatial planting arrangement (mixtures vs. monoculture strips), seed coating technology, and species identity (five native grasses) to affect standing biomass and seeded plant density in experimental greenstrips.
