The timely development of the nation's energy production capacity in a manner that minimizes potential adverse local and regional impacts associated with energy facilities requires the use of sophisticated techniques for evaluation of siting alternatives and fuel cycle options. This report is a documentation of the computerized SITE methodology that has been developed for evaluating health, environmental, and socioeconomic impacts related to utilization of alternate sites for energy production within a region of interest. The cost, impact, and attribute vectors, which are generated and displayed on density maps, can be used in a multiparameter overlay process to identify preferable siting areas. The assessment of...
Sage-grouse (Centrocercus spp.) populations have declined dramatically throughout the western United States since the 1960s. Increased gas and oil development during this time has potentially contributed to the declines. I investigated impacts of development of natural gas fields on greater sage- grouse (C. urophasianus) breeding behavior, seasonal habitat selection, and population growth in the upper Green River Basin of western Wyoming. Greater sage-grouse in western Wyoming appeared to be excluded from attending leks situated within or near the development boundaries of natural gas fields. Declines in the number of displaying males were positively correlated with decreased distance from leks to gas-field-related...

This publication provides the most complete information available on the status of rare vertebrate species and vascular plant species in Wyoming. It updates and replaces previous lists (Fertig and Beauvais 1999, Fertig and Heidel 2002), and documents 473 plants and 125 vertebrates of conservation and management concern in Wyoming. For each species, a summary of factors used in weighing species’ status including distribution, abundance, trends, and intrinsic vulnerability, is also provided. Interest in rare species has increased substantially over the past 40 years, and currently there is broad support for the conservation of rare plants and animals in North America. Natural resource managers, policy makers, and...
Mule deer within the Dubois herd make several long-distance migrations into the heart of the Greater Yellowstone Ecosystem (fig. 26). These migrations originate from winter range in the warm, protected sagebrush valley surrounding Dubois, Wyoming, and extend to the southeast on the Wind River Reservation. Each spring, an estimated 6,000–7,000 deer leave this valley and the Reservation and migrate northwest. These journeys, averaging 44 mi one way, begin as deer ascend Togwotee Pass (9,658 ft [m 2,944] in elevation). From there, they cross challenging natural terrain with high mountain passes and disperse into the north Wind River Range, Gros Ventre Range, Absaroka Range, Grand Teton National Park, and deep into...
As policy makers consider strategies to reduce greenhouse gas emissions, they need to understand the available options and the conditions under which these options become economically attractive. This paper explores the economics of carbon capture and sequestration technologies as applied to electric generating plants. The MIT Emissions Prediction and Policy Analysis (EPPA) model, a general equilibrium model of the world economy, is used to model two of the most promising carbon capture and sequestration (CCS) technologies. The CCS technologies are based on a natural gas combined cycle plant and an integrated coal gasification combined cycle plant. Additionally, the role of natural gas combined cycle plants without...
FY2014Although the future of sage grouse depends on the future of sagebrush, we have limited ability to anticipate impacts of climate change on sagebrush populations. Current efforts to forecast sagebrush habitat typically rely on species distribution models (SDMs), which suffer from a variety of well-known weaknesses. However, by integrating SDMs with complementary research approaches, such as historical data analysis and mechanistic models, we can provide increased confidence in projections of habitat change. Our goal is to forecast the effect of climate change on the distribution and abundance of big sagebrush in order to inform conservation planning, and sage grouse management in particular, across the Intermountain...
Mule deer within the Upper Shoshone herd make a number of significant, long-distance migrations west into the core of the Greater Yellowstone Ecosystem. The longest is a 133-mile (214-km) migration that originates at the mouth of the South Fork of the Shoshone River near Buffalo Bill Reservoir and ends at Jenny Lake in Grand Teton National Park. Deer in the Upper Shoshone herd winter in the lower-elevation sagebrush valleys of the South Fork Shoshone River and North Fork of the Shoshone River. Each spring, an estimated 6,700 deer head west into the high-elevation, mountainous country of the Absaroka Range and then into Yellowstone National Park or Grand Teton National Park. These challenging journeys, an average...

FY2010In addition to regional Science and Traditional Ecological Knowledge projects that the Great Basin LCC (GBLCC) supports, GBLCC staff lend technical expertise to a range of projects and have contributed to important regional publications on a range of subjects. These publications range in type from textbooks, to management-oriented science and conservation plans, to scientific papers and have covered subjects like wind erosion following fire, soil microbiota response to drought, plant community resilience to invasive species, and alpine plant communities. In many cases these publications form foundations for scientifically-informed management strategies across the Great Basin.

The Wyoming Cooperative Fish and Wildlife Research Unit was authorized by the United States Congress in 1977. There are five cooperators: (1) U.S. Geological Survey (USGS), (2) U.S. Fish and Wildlife Service (USFWS), (3) University of Wyoming (UW), (4) Wyoming Game and Fish Department (WGFD), and (5) Wildlife Management Institute. The primary Department of Interior cooperator was changed from USFWS to the USGS in 1996. The Units are now housed in the Biological Resources Division of USGS. Under the cooperative agreement, the Unit is charged to provide research and technical assistance to the WGFD, other Federal and state agencies, and private institutions, and to train graduate students in fisheries and wildlife...

Mule deer within the Clarks Fork herd make a number of significant westward long-distance migrations. These migrations originate north of Cody, near Heart Mountain and along the foothills of Absaroka Front. There, deer winter in the lower elevation sagebrush valleys, and in spring an estimated 2,700 deer head west into the high elevation mountain valleys of the Absaroka Range and Yellowstone National Park. This herd summers along the Lamar River, Cache Creek, and the Clarks Fork of the Yellowstone. The longest migration is 68 miles and ends just north of Yellowstone Lake along the Yellowstone River in the Hayden Valley. These challenging journeys, an average of 38 miles long, cross rugged terrain and steep mountain...
The success of carbon capture, storage and sequestration as a greenhouse gas mitigation strategy will be, in part, dependent on the regulatory framework used to govern its implementation. Creating a science-based regulatory framework that is designed with enough flexibility to encourage greenhouse gas offset activity, effective means of measuring the costs of taking action to reduce greenhouse gas emissions, and ample protection for human and ecosystem health may prove challenging. For the purposes of this paper we will assume that there is an existing incentive to capture, store and sequester carbon and focus on how to regulate the process. Accounting practices and precursory crediting rules for biological sinks...

During June and July of 2006 thirty-two landscape photographs from three early explorations of Arctic Alaska were reproduced. The pairs of historic and contemporary photos provided the opportunity to observe arctic landcover change over fifty and one hundred year time periods. Qualitative photo-pair comparisons revealed: glacier and aufeis cover has decreased; lake and pond cover has both increased and decreased; observations of decreased river channel cover were more common than increased river channel cover; and observations of increased tundra, shrub, and tree cover were more common than decreased tundra, shrub, and tree cover. The character of these observations suggests a landscape wide response to observed...
Mule deer within the South Wind River herd make short- and medium-distance migrations from the foothills near Lander, Wyoming, into the Wind River Range and around its southern flanks (fig. 31). The longest migration in this herd is a 75-mile (121-km) route originating south of Lander near Twin Creek. Deer following this long-distance route traverse the southern edge of the Wind River Range and summer in the mountainous terrain at the head of the Big Sandy River. Some deer make medium-distance migrations, traveling 14–51 mi (23–82 km) northwest of Sweetwater Station to summer range in the northern Great Divide Basin. Meanwhile, other deer in this population make short- and medium-distance migrations of 7–59 mi (11–95...

A polygon feature class representing the spatial extent and boundaries for BLM Wild Horse and Burro Herd Management Areas (HMAs) and Herd Areas (HAs), along with USFS Wild Horse and Burro Territories (WHBTs). HMAs and WHBTs are color coded to represent whether they are within Appropriate Management Level (AML), Greater than 100% and less than 200% of AML, and greater than 200% of AML. HAs do not have associated AML values, and are colored grey.
FY2015Persistent ecosystem and anthropogenic disturbances and stressors are threatening sustainability of sagebrush ecosystems in the western US, and managers and policy makers are seeking strategic, holistic approaches for species conservation and ecosystem restoration. Recent research indicates that an understanding of ecosystem resilience to disturbance and resistance to nonnative invasive species can be used to prioritize management activities across large landscapes and determine the most appropriate actions at project scales. An interagency WAFWA working group has linked this understanding with breeding habitat probabilities for Greater and Gunnison sage-grouse, and developed a habitat decision matrix for...
