The Wyoming Landscape Conservation Initiative (WLCI)
The Wyoming Landscape Conservation Initiative (WLCI) addresses effects of land-use and habitat 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, and it continues on that trajectory today. However, the effects of renewable energy development on wildlife and habitats...
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

No substitute for survival: Perturbation analyses using a Golden Eagle population model reveal limits to managing for take 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 histories to better understand how...

Large-scale control site selection for population monitoring: an example assessing Sage-grouse trends Large-scale control site selection for population monitoring: an example assessing Sage-grouse trends
Human impacts on wildlife populations are widespread and prolific and understanding wildlife responses to human impacts is a fundamental component of wildlife management. The first step to understanding wildlife responses is the documentation of changes in wildlife population parameters, such as population size. Meaningful assessment of population changes in potentially impacted sites...

Landscape characteristics influencing the genetic structure of greater sage-grouse within the stronghold of their range: a holistic modeling approach Landscape characteristics influencing the genetic structure of greater sage-grouse within the stronghold of their range: a holistic modeling approach
Given the significance of animal dispersal to population dynamics and geographic variability, understanding how dispersal is impacted by landscape patterns has major ecological and conservation importance. Speaking to the importance of dispersal, the use of linear mixed models to compare genetic differentiation with pairwise resistance derived from landscape resistance surfaces has...

Broad-scale assessments of ecological landscapes: developing methods and applications Broad-scale assessments of ecological landscapes: developing methods and applications
The U.S. Department of the Interior (DOI) Bureau of Land Management (BLM) is developing a Landscape Approach for managing multiple uses of public lands by incorporating multiscale information to quantify the effects of natural and human influences on natural resource conditions and trends. A primary goal of the approach is to identify opportunities for resource conservation, restoration...

Assessment of surface water chloride and conductivity trends in areas of unconventional oil and gas development — Why existing national data sets cannot tell us what we would like to know Assessment of surface water chloride and conductivity trends in areas of unconventional oil and gas development — Why existing national data sets cannot tell us what we would like to know
Heightened concern regarding the potential effects of unconventional oil and gas development on regional water quality has emerged, but the few studies on this topic are limited in geographic scope. Here we evaluate the potential utility of national and publicly available water-quality data sets for addressing questions regarding unconventional oil and gas development. We used existing U...

Ecological risks of shale oil and gas development to wildlife, aquatic resources and their habitats Ecological risks of shale oil and gas development to wildlife, aquatic resources and their habitats
Technological advances in hydraulic fracturing and horizontal drilling have led to the exploration and exploitation of shale oil and gas both nationally and internationally. Extensive development of shale resources has occurred within the United States over the past decade, yet full build out is not expected to occur for years. Moreover, countries across the globe have large shale...
