“The loss of foundational but fire-intolerant perennials such as sagebrush due to increases in fire size and frequency in semi-arid regions has motivated efforts to restore them, often with mixed or even no success. Seeds of sagebrush Artemisia tridentata and related species must be moved considerable distances from seed source to planting sites, but such transfers have not been guided by an understanding of local climate adaptation. Initial seedling establishment and its response to weather are a key demographic bottleneck that likely varies among subspecies and populations of sagebrush.We assessed differences in survival, growth and physiological responses of sagebrush seedlings to weather among eleven seed sources...
This research project documented the Native American cultural traditions in the Duckwater Shoshone and the Paiute tribes’ responses to climate change in the Great Basin region. Aspects of tribal culture often include fish, wildlife, or plants as central images or main symbolic figures. Because climate change affects the presence, abundance and patterns of distribution of animals and plants, it is important to analyze behaviors connected to those resources. This project carried out research pertaining to the effects of climate on aspects of the environment and resources relevant to these two Great Basin tribes, leading to insights regarding possible responses of tribal culture to focal animals and plants that, in...

Bromus species – such as cheatgrass – are exotic annual grasses that have become the dominant annual grasses in the western hemisphere. Their spread and impacts across the western United States continue despite the many attempts by land managers to control these species. A new book edited by scientists from the U.S. Geological Survey, U.S. Forest Service and Colorado State University answers critical research, planning, and management questions about these species. The book synthesizes available literature on the biology, ecology, sociology and economics of Bromus grasses to develop a more complete picture of the factors that influence their invasiveness, impacts, and management in the western United States. Lessons...
The Great Basin LCC Conservation Planning Atlas (CPA) brings cloud-based functionality and collaborative features to a geospatial platform for conservation initiatives across the Great Basin. The CPA resides within the Data Basin online platform, allowing users and groups to create unique collaborative mapping products for their projects. Drawing on over 16,000 datasets currently in Data Basin–including high-priority datasets from LANDFIRE, BLM, USGS, and others–users are able to share maps within public or private groups and then to dynamically interact with those products as a group. In addition to the collaborative planning features, the CPA also provides the Great Basin LCC with another platform through which...
The Science Framework is intended to link the Department of the Interior’s Integrated Rangeland Fire Management Strategy with long-term strategic conservation actions in the sagebrush biome. The Science Framework provides a multiscale approach for prioritizing areas for management and determining effective management strategies within the sagebrush biome. The emphasis is on sagebrush (Artemisia spp.) ecosystems and Greater sage-grouse (Centrocercus urophasianus). The approach provided in the Science Framework links sagebrush ecosystem resilience to disturbance and resistance to nonnative, invasive plant species to species habitat information based on the distribution and abundance of focal species. A geospatial...
Worldwide, many species are responding to ongoing climate change with shifts in distribution, abundance, phenology, or behavior. Consequently, natural-resource managers face increasingly urgent conservation questions related to biodiversity loss, expansion of invasive species, and deteriorating ecosystem services. We argue that our ability to address these questions is hampered by the lack of explicit consideration of species’ adaptive capacity (AC). AC is the ability of a species or population to cope with climatic changes and is characterized by three fundamental components: phenotypic plasticity, dispersal ability, and genetic diversity. However, few studies simultaneously address all elements; often, AC is confused...
On July 26, 2017, Bruce Wylie and Stephen Boyte, USGS, discussed their recent research mapping herbaceous annual cover in the Great Basin.The research team utilized regression tree algorithms combined with spectral and ancillary data (for elevation, soils, etc.) to achieve accuracy-focused maps. They used high-resolution satellite data (2m) to scale ground observations to levels compatible with moderate-resolution satellites (Landsat and MODIS). The speakers also discussed data access, selected journal publications and future plans during the webinar.
On July 21, 2016, Dr. Samantha Chisholm Hatfield of Oregon State University presented findings from her research on Native cultural responses to climate change in the Great Basin.Traditional Ecological Knowledge (TEK) is based on observations of environmental surroundings over long periods of time. It is an integral aspect of Indigenous cultural knowledge, which is holistic in nature. Because climate change affects the presence, abundance and patterns of distribution of animals and plants, it is important to analyze behaviors and hear tribes’ TEK perspectives connected to those resources. In this project, researchers documented the Duckwater Shoshone and the Paiute tribes’ cultural traditions and responses to climate...
The Great Basin Landscape Conservation Cooperative draws on its Steering Committee and Science and Traditional Ecological Knowledge (S-TEK) partners to prioritize and support conservation science across the Great Basin region. Over nine years, GBLCC has distributed $3.3 million in direct funds and leveraged an additional $5.2 million in matching and in-kind contributions to 50 projects including sagebrush modelling under climate scenarios, tribal adaptations to climate change, mapping of wetlands across the region and many more.
Understanding local and geographic factors influencing species distributions is a prerequisite for conservation planning. Our objective in this study was to model local and geographic variability in elevations occupied by native and nonnative trout in the northwestern Great Basin, USA. To this end, we analyzed a large existing data set of trout presence (5,156 observations) to evaluate two fundamental factors influencing occupied elevations: climate-related gradients in geography and local constraints imposed by topography. We applied quantile regression to model upstream and downstream distribution elevation limits for each trout species commonly found in the region (two native and two nonnative species). With...
On September 26, Jeanne Chambers, U.S. Forest Service Rocky Mountain Research Station, and Steve Hanser, U.S. Geological Survey, discussed the tools and methods developed as part of the Science Framework for the Conservation and Restoration Strategy of Sec. Order 3336.Co-hosted by the Great Basin, Great Northern, Plains and Prairie Potholes and Southern Rockies Landscape Conservation Cooperatives Department of the Interior Secretary Order 3336 called for the development of a comprehensive, science-based strategy to reduce the threat of large-scale rangeland fire to greater sage-grouse habitat and the sagebrush steppe ecosystem. The four Landscape Conservation Cooperatives (LCCs) of the sagebrush steppe are pleased...
Quaking aspen (Populus tremuloides Michx.) is the most widespread tree species in North America, and it is found throughout much of the Mountain West (MW) across a broad range of bioclimatic regions. Aspen typically regenerates asexually and prolifically after fire, and due to its seral status in many western conifer forests, aspen is often considered dependent upon disturbance for persistence. In many landscapes, historical evidence for post-fire aspen establishment is clear, and following extended fire-free periods senescing or declining aspen overstories sometimes lack adequate regeneration and are succeeding to conifers. However, aspen also forms relatively stable stands that contain little or no evidence of...
This research highlights development and application of an integrated hydrologic model (GSFLOW) to a semiarid, snow-dominated watershed in the Great Basin to evaluate Pinyon-Juniper (PJ) and temperature controls on mountain meadow shallow groundwater. The work used Google Earth Engine Landsat satellite and gridded climate archives for model evaluation. Model simulations across three decades indicated that the watershed operates on a threshold response to precipitation (P) >400 mm/y to produce a positive yield (P-ET; 9%) resulting in stream discharge and a rebound in meadow groundwater levels during these wetter years. Observed and simulated meadow groundwater response to large P correlates with above average predicted...
Populations of Greater Sage-grouse have declined across the entire range of the species and habitat loss is considered to be the most important factor contributing to these declines (e.g., Connelly et al. 2004). Agricultural conversion, energy development, feral horses, and livestock grazing are hypothesized to contribute to habitat related threats (Range wide interagency sage grouse conservation team 2012). Substantial research has been completed to assess the effects of energy development (e.g., Walker et al. 2007) and agricultural conversion (e.g., Aldridge et al. 2008), yet, little research has been devoted to understanding the impacts of grazing by feral horses and livestock on sage-grouse demography.The Sheldon-Hart...
The North American Bat Monitoring Program (NABat) is a large-scale, long-term monitoring program designed to assess the status and trends of North American bats at local, regional, and range-wide scales. Spanning the United States, Canada, and Mexico, NABat brings together an extensive network of partners who utilize the NABat program design and monitoring protocols to collect bat population data. These data are analyzed at various spatial and temporal scales and results are used to promote effective conservation actions to ensure the long-term viability of bat populations across the continent.

The rate at which new information about stream resources is being created has accelerated with the recent development of spatial stream-network models (SSNMs), the growing availability of stream databases, and ongoing advances in geospatial science and computational efficiency. To further enhance information development, the National Stream Internet (NSI) project was developed as a means of providing a consistent, flexible analytical infrastructure that can be applied with many types of stream data anywhere in the country. A key part of that infrastructure is the NSI network, a digital GIS layer which has a specific topological structure that was designed to work effectively with SSNMs. The NSI network was derived...

Emerging applications of ecosystem resilience and resistance concepts in sagebrush ecosystems allow managers to better predict and mitigate impacts of wildfire and invasive annual grasses. Soil temperature and moisture strongly influence the kind and amount of vegetation, and consequently, are closely tied to sagebrush ecosystem resilience and resistance (Chambers et al. 2014). Soil taxonomic temperature and moisture regimes can be used as indicators of resilience and resistance at landscape scales to depict environmental gradients in sagebrush ecosystems that range from cold/cool-moist sites to warm-dry sites. We aggregated soil survey spatial and tabular data to facilitate broad-scale analyses of resilience and...

The exotic annual grass Bromus tectorum (cheatgrass) dominates vast acreages of rangeland in the western USA, leading to increased fire frequency and ecosystem degradation that is often irreversible. Episodic regeneration failure (“die-off”) has been observed in cheatgrass monocultures and can have negative ecosystem consequences, but can also provide an opportunity for restoration of native species and ecological function within the imperiled sagebrush steppe ecosystem. Proximate causes of cheatgrass die-off are uncertain, although several taxa of fungal soil pathogens have been implicated. Die-off occurrence is stochastic and can occur in remote areas. Thus, developing remote sensing indicators that are repeatable...
