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...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
