A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Wildlife Biology Utah State University, Logan, Utah Abstract: "Declines in the distribution and abundance of greater sage-grouse ( Centrocercus urophasianus ; hereafter “sage - grouse” ) in western North America over the past century have been severe. The goal of my research was to increase the understanding of factors influencing where sage-grouse hens placed their nests, how common ravens ( Corvus corax : hereafter “raven” ) impacted sage-grouse nest success, and whether high raptor densities negatively impacted hen survival of sage-grouse. I compared raven and raptor densities at sage-grouse nest...
Black Gold is a collection of nine articles looking at specific individuals, oil fields, issues, and oil companies in the history of Wyoming's oil industry. Individually, each chapter focuses on an important item or incident in that history; together they illustrate patterns in the development of Wyoming's oil industry. The reader will come to see the important roll played by big business and the federal government in Wyoming's oil history. This roll at times contributed to, and at other times retarded, the development of Wyoming's oil industry.
Microtus richardsoni, the water vole, was listed as a sensitive species in Region 2 of the USDA Forest Service in 1994. Historical records indicate water voles were found in the Big Horn Mountains, but little was known about their current status. The purpose of this study was to locate water voles in the Big Horn Mountains of Wyoming, develop a habitat profile, and evaluate the extent to which livestock grazing affects them. Accessible creeks with habitat requirements for water voles were surveyed. Water voles were not captured below 2440 m. Grazed and ungrazed sites occupied by water voles were matched and analyzed for percent plant cover, dry weight biomass, riparian classification, mean stream depth, channel...
Native fishes of the Upper Colorado River Basin have experienced substantial declines in abundance and distribution, and are extirpated from most of Wyoming. Muddy Creek, in south-central Wyoming (Little Snake River watershed), contains sympatric populations of native roundtail chub (Gila robusta), bluehead sucker, (Catostomus discobolus), and flannelmouth sucker (C. latipinnis), and represents an area of high conservation concern because it is the only area known to have sympatric populations of all 3 species in Wyoming. However, introduced creek chub (Semotilus atromaculatus) are abundant and might have a negative influence on native fishes. We assessed summer food habits of roundtail chub and creek chub to provide...

This is a collaborative, two-part project to compile and analyze resource data to support WLCI efforts. Part 1 entails directing data synthesis and assessment activities to ensure that they will inform and support the WLCI LPDTs and Coordination Team in their conservation planning efforts, such as developing conservation priorities and strategies, identifying priority areas for conservation actions, evaluating and ranking conservation projects, and evaluating spatial and ecological relations between proposed habitat projects and WLCI priorities. In FY2014, we helped the Coordination Team complete the WLCI Conservation Action Plan and BLM’s annual report, and we provided maps and other materials to assist with ranking...

We revised distribution maps of potential presettlement habitat and current populations for Greater Sage-Grouse (Centrocercus urophasianus) and Gunnison Sage-Grouse (C. minimus) in North America. The revised map of potential presettlement habitat included some areas omitted from previously published maps such as the San Luis Valley of Colorado and Jackson area of Wyoming. Areas excluded from the revised maps were those dominated by barren, alpine, and forest habitats. The resulting presettlement distribution of potential habitat for Greater Sage-Grouse encompassed 1 200 483 km(2), With the species' current range 668 412 km(2). The distribution of potential Gunnison Sage-Grouse habitat encompassed 46 521 km(2), with...
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...
The Protected Areas Database of the United States (PAD-US) is a geodatabase that illustrates and describes public land ownership, management and conservation lands nationally, including voluntarily provided privately protected areas. The lands included in PAD-US are assigned conservation measures that qualify their intent to manage lands for the preservation of biological diversity and to other natural, recreational and cultural uses; managed for these purposes through legal or other effective means. The geodatabase includes: 1) Geographic boundaries of public land ownership and voluntarily provided private conservation lands (e.g., Nature Conservancy Preserves); 2) The combination land owner, land manager, management...

Link to Metadata. Abstract from metadata: This open-file report presents the results of the USGS Mineral Resources Program activity to compile a national-scale geologic map database to support national and regional level projects, including mineral resource and geo- environmental assessments. The only comprehensive sources of regional- and national-scale geologic maps are state geologic maps with scales ranging from 1:100,000 to 1:1,000,000. Digital versions of these state maps form the core of what is presented here. Because no adequate geologic map exists for the state of Alaska, it is being compiled in regional blocks that also form part of this national database. It is expected that this series will completed...

The national dataset was clipped to the WLCI envelope by USGS staff. No other processing was performed on the dataset. This map layer is commonly called Bailey's ecoregions and shows ecosystems of regional extent in the United States, Puerto Rico, and the U.S. Virgin Islands. Four levels of detail are included to show a hierarchy of ecosystems. The largest ecosystems are domains, which are groups of related climates and which are differentiated based on precipitation and temperature. Divisions represent the climates within domains and are differentiated based on precipitation levels and patterns as well as temperature. Divisions are subdivided into provinces, which are differentiated based on vegetation or other...

This project would increase diversity of forbs and invertebrates in riparian and transitional riparian/upland areas through mowing and seeding of native forb species. A tractor powered mower with a seeder would be used to create an enhanced vegetative mosaic within riparian or transitional riparian areas lacking in vegetative species and structural diversity. A contractor would provide a tractor or seeder for distribution of native seed. This project would focus on improving habitat for a diversity of species, particularly sage grouse and other BLM sensitive avian species such as the Brewer's sparrow and sage thrasher, which rely on riparian habitats for critical brood rearing requirements in the Sand Hills ACEC...

This project will provide for deer crossing the Baggs highway (789) to reduce vehicle collisions. Construction of 3-4 miles of deer proof fence to funnel a portion of a migrating deer herd to existing culvert under HWY 789 to reduce deer vehicle collissions. Installation of 6 cattleguards in current access points to prevent deer access through fences at these points. Further, the project would cover several years and work toward providing safe wildlife passage. Industry and WDOT are being approached to partner with the WGFD on this project. Providing deer crossings of HWY 789 will reduce the incidences of vehicle and deer collisions, reducing deer mortality and damage to vehicles. The project would be done in a...
