The Platte Valley Herd Corridor was designated by the Wyoming Game and Fish Department in 2018 (fig. 30). The Platte Valley herd contains approximately 11,000 mule deer. The corridor is based on two wintering populations, including a south segment from Saratoga, Wyoming, to the Colorado State line, and a north segment from Saratoga to the Dana Ridge area north of I-80. Winter ranges in the Platte Valley are more dispersed than winter ranges in other parts of the state, so deer migrate in many different directions. Many deer in the southern segment follow the Platte River south to summer ranges in Colorado. Most deer migrations in the north radiate south and east from winter ranges along I-80. The WGFD collared 45...
Understanding the sources and quantities of greenhouse gas (GHG) emissions is critical to developing an emissions inventory that accurately represents various oil and gas industry segment operations. To address this, the American Petroleum Institute (API) formed a Greenhouse Gas Emissions Methodology Working Group. The working group’s objectives were to review, summarize and recommend methodologies for consistent estimation of GHG emissions from oil and gas industry facilities, including exploration and production through refining to product marketing. In a continued pursuit of consistent emission estimation methodologies for the oil and gas industry, the working group is meeting with other protocol development...
Rising global demand for energy, high energy prices, climate change, and the threat of terrorism all point to the need for greater energy efficiency and conservation in the United States. While technological innovation is plainly needed, our laws and institutional arrangements must also play an important role. The United States has scores of legal and policy tools from which to choose to improve energy efficiency and curb energy consumption. This Article, which grows out of a Spring 2006 seminar at theWidener University School of Law, evaluates a handful of these tools: transit-oriented development; fuel taxation; real-time pricing for electricity use; public benefit funds; improving the efficiency of existing residential...

The Crow Mesa Mule Deer Study was initiated in 2019 to identify the seasonal movement and distribution patterns of mule deer in the eastern half of Game Management Unit (GMU) 2C. This GPS study builds on nearby studies of mule deer and elk conducted by the Bureau of Land Management, the Southern Ute Tribe, the Jicarilla Apache Nation, and the New Mexico Department of Fish and Game. Migration corridors extended 20 to 75 miles from the winter ranges in GMU 2C to various summer ranges northeast to the Carson National Forest near Chama, and southeast to the San Pedro Parks Wilderness in the Santa Fe National Forest. The Crow Mesa herd relies largely on winter ranges administered by the Bureau of Land Management, where...

We flew aerial line transect surveys between March 30 and May 3, 2012, to estimate the abundance of lesser prairie-chickens (Tympanuchus pallidicinctus) and lesser prairie-chicken leks in four habitat regions in the Great Plains U.S. Estimates were supplemented with data from surveys conducted by Texas Tech University in two regions in the Texas Panhandle and surveys conducted by the Oklahoma Department of Wildlife Conservation in Oklahoma. We also estimated the number of mixed species leks which contained both lesser and greater prairie-chickens (Tympanuchus cupido) and the number of hybrid lesser-greater prairie-chickens. The study area for 2012 included four regions containing the 2011 estimated occupied lesser...

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.
