Annotated Bibliography of Scientific Research on Greater Sage-Grouse
The greater sage-grouse has been a focus of scientific investigation and management action for the past two decades. 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.
Greater Sage-Grouse Science (2015–17): Synthesis and Potential Management Implications
USGS led an interagency team of Federal and State agency biologists to develop a report that synthesizes greater sage-grouse scientific literature.
Higher and Farther: Patterns of Development within Protected Areas
There is a well-known bias in the location of protected areas both within the US and globally. Lands protected for conservation tend to be located on less productive soils at high elevations far from cities. USGS is exploring whether this ‘high and far’ paradigm applies within protected areas as well. That is, does human modification within lands that already have some degree of protection, also...
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...
Wyoming Landscape Conservation Initiative: Baseline Synthesis
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 natural...

Conservation of Sagebrush Ecosystems and Wildlife
Sagebrush ecosystems are diverse habitats found throughout western North America that support a variety of flora and fauna. Home to unique wildlife such as Sage-grouse, Sage Thrashers, Brewer's Sparrows, Ferruginous Hawks, and pygmy rabbits, these ecosystems have undergone intense changes since the time when millions of bison roamed the plains. European settlement and intense agricultural...
Resources for Understanding the Effects of Wind Energy Development
As the Nation strives to lessen its dependence on foreign oil, domestic energy production has increased dramatically. This is especially true for renewable energy sources such as wind: from 2007 to 2009, for example, wind energy development increased 341 percent in Wyoming (Fig. 1, Science tab), and it continues on that trajectory today. However, the effects of renewable energy development on...
Hydraulic Fracturing and Water Resources: An Assessment of the Potential Effects of Shale Gas Development on Water Resources in the United States
Shale gas is a key source of onshore domestic energy for the United States and production of this resource is increasing rapidly. Development and extraction of shale gas requires hydraulic fracturing, which entails horizontal drilling, perforation of steel casing and cement grout using explosive charges, and expansion of fractures using fluids under high pressure. Concern over potential environmen
