Energy Development and Changing Land Uses
Applied research and integrated regional assessments emphasize spatially explicit analyses of ecosystem components affected by energy development and land-use change in the western United States. Topics include sagebrush-steppe ecology; sagebrush habitat assessments; the effets of human activities (including energy development, transportation, and recreation) on habitats and wildlife behavior...
The Wyoming Landscape Conservation Initiative (WLCI)
The Wyoming Landscape Conservation Initiative (WLCI) addresses effects of land-use and climate changes on Southwest Wyoming’s natural resources. In partnership with twelve Federal, State, and local natural resource agencies, and non-governmental organizations– FORT and ten other USGS centers are conducting dozens of integrated science projects to assess the status of Southwest Wyoming’s...
Science to Support an Assessment of Future Climate Impacts on Wildlife in Wyoming
In response to the potential impacts of climate and land use change to the Nation’s ecosystems, the Bureau of Land Management (BLM) launched a series of Rapid Ecoregional Assessments (REAs) in 2010. The REAs are focused on improving our understanding of the current state of ecosystems and how conditions may be impacted by changes in climate, land use, and other stressors. Researchers with...
Using a Collaborative Modeling Approach to Explore Climate and Landscape Change in the Northern Rockies and Inform Adaptive Management
Federal land managers need an adaptive management framework to accommodate changing conditions and that allows them to effectively link the appropriate science to natural resource management decision-making across jurisdictional boundaries. FRAME-SIMPPLLE is a collaborative modeling process designed to accomplish this goal by coupling the adaptive capabilities of the SIMPPLLE modeling system...
Energy and Environment in the Rocky Mountain Area (EERMA)
The Energy and Environment in the Rocky Mountain Area (EERMA) project is composed of interdisciplinary U.S. Geological Survey (USGS) scientists working to provide land management agencies and decision makers with information. The purpose of the Interactive Energy Atlas is to provide data and decision support tools to visualize and assess the potential effects of energy development.
Surface area of solar arrays in the conterminous United States
The U.S. Geological Survey (USGS) Fort Collins Science Center created a national data set of the footprint area of solar arrays for the Bureau of Land Management’s National Operations Center. As of 2015, solar arrays covered 191.57 square kilometers. There were 176 utility-scale solar facilities on impervious surfaces and 564 facilities on non-impervious surfaces.
Using scenarios to evaluate vulnerability of grassland communities to climate change in the Southern Great Plains of the United States
Scenario planning is a useful tool for identifying key vulnerabilities of ecological systems to changing climates, informed by the potential outcomes for a set of divergent, plausible, and relevant climate scenarios. We evaluated potential vulnerabilities of grassland communities to changing climate in the Southern Great Plains (SGP) and the...

Quantifying ecological integrity of terrestrial systems to inform management of multiple-use public lands in the United States
The concept of ecological integrity has been applied widely to management of aquatic systems, but still is considered by many to be too vague and difficult to quantify to be useful for managing terrestrial systems, particularly across broad areas. Extensive public lands in the western United States are managed for diverse uses such as timber...

Biophysical assessment for indemnity selection of Federal Lands in Colorado
Information on the biophysical features of Federal lands identified as suitable for transfer to the State of Colorado was requested by the Bureau of Land Management (BLM). This information is intended for use in conducting an Environmental Assessment prior to the transfer of ownership (conveyance) to the State. The Colorado State Land Board filed...

Greater sage-grouse science (2015–17)—Synthesis and potential management implications
Executive SummaryThe greater sage-grouse (Centrocercus urophasianus; hereafter called “sage-grouse”), a species that requires sagebrush (Artemisia spp.), has experienced range-wide declines in its distribution and abundance. These declines have prompted substantial research and management investments to improve the understanding of sage-grouse and...
