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,...
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...

Tools for Managing and Monitoring Sage Grouse
To better understand how land-use changes are affecting greater sage-grouse (Centrocercus urophasianus), FORT is collaborating with USGS centers FRESC, GECSC, WERC, and EROS; the BLM; Colorado State University; and the WLCI to develop information and tools for managing and monitoring grouse.
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...
Annotated bibliography of scientific research on greater sage-grouse published from 2015 to 2019
The greater sage-grouse (Centrocercus urophasianus; 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...

Ecological forecasting—21st century science for 21st century management
Natural resource managers are coping with rapid changes in both environmental conditions and ecosystems. Enabled by recent advances in data collection and assimilation, short-term ecological forecasting may be a powerful tool to help resource managers anticipate impending near-term changes in ecosystem conditions or dynamics. Managers may use the...

Bridging the research-management gap: Landscape ecology in practice on public lands in the western United States
The field of landscape ecology has grown and matured in recent decades, but incorporating landscape science into land management decisions remains challenging. Many lands in the western United States are federally owned and managed for multiple uses, including recreation, conservation, and energy development. We argue for stronger integration of...

Jamie; Weltzin, Jake F. Ecosystem processes, landcover, climate, and human settlement shape dynamic distributions for golden eagle across the western US
Species–environment relationships for highly mobile species outside of the breeding season are often highly dynamic in response to the collective effects of ever‐changing climatic conditions, food resources, and anthropogenic disturbance. Capturing dynamic space‐use patterns in a model‐based framework is critical as model inference often drives...

No substitute for survival: Perturbation analyses using a Golden Eagle population model reveal limits to managing for take
Conserving populations of long-lived birds of prey, characterized by a slow life-history (e.g., high survival and low reproductive output), requires a thorough understanding of how variation in their vital rates differentially affects population growth. Stochastic population modeling provides a framework for exploring variation in complex life...
