Conflict Within Wildlife Management On Western Landscapes Home On The Range, Trisha A. Hedin

All Graduate Theses and Dissertations, Fall 2023 to Present

Most of the public lands within the Intermountain West are administered under a multiple-use mandate which emphasizes striking a balance in land use planning among the potentially competing values of livestock grazing, timber production, water supply, extraction of valuable fossil fuels, wildlife, and wilderness. This research sought to dive into a few of these competing values that involve large herbivores that compete for limited forage resources such as livestock and wildlife, on public lands, but also touched upon wildlife on private lands. The first component of research looked specifically at the coexistence of wildlife and livestock on both public and …

Stewards And Conservationists: Merging Moral Norms And The Theory Of Planned Behavior To Understand Altruistic Conservation Behavior Among Hunters In Southwestern Utah, Jacob C. Richards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The leading cause of mortality in California Condors (condors) is lead poisoning, which occurs when condors ingest lead-based ammunition left in carcasses. As a critically endangered species with approximately 115 individuals remaining in the American southwest, increasing the adoption of non-lead ammunition is essential to the recovery of the species. In Utah, the Division of Wildlife Resources (DWR) uses communication with hunters as the primary tool for increasing the adoption of non-lead ammunition in southwestern Utah. In this research, we use social science theory and data collected from a survey of hunters throughout the region to develop a strategic communication …

Human-Wildlife Interactions In Bryce Canyon National Park, Chad H. Wildermuth

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Public lands such as National Parks protect some of America’s most spectacular and iconic natural, cultural, and historic landscapes. These lands are managed with a goal of preserving their unique features for the recreational use of the public. Therefore, it is important to understand the effects, if any, that public visitation has on these natural systems. This study investigated human-wildlife interactions in Bryce Canyon National Park (BRCA), Utah in order to better understand factors that lead to human-wildlife conflicts and how the attitudes and perceptions of visitors affect their actions towards wildlife.

Observations of human-wildlife interactions were observed and measured …

Understanding Wetlands And Irrigation In The Little Snake River Basin, Wyoming, Lindsey Washkoviak

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Little Snake River Basin (LSRB) is a managed basin in South-central Wyoming located within the Colorado River watershed facing severe water shortages. There is increased pressure on water resource managers and agricultural producers to adopt water efficiency practices that could negatively affect wetland resources. However, studies have begun to quantify the importance of irrigation for recharging groundwater, maintaining late season instream flows, and maintaining and creating wetlands that provide wildlife habitat and ecosystem services.

In the LSRB there are 11,636 acres of wetlands; 56% of which overlap with irrigation. Conversion to more efficient irrigation could reduce water availability to …

Utilizing Remote Sensing And Geospatial Techniques To Determine Detection Probabilities Of Large Mammals, Patricia A. Terletzky-Gese

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Whether a species is rare and requires protection or is overabundant and needs control, an accurate estimate of population size is essential for the development of conservation plans and management goals. Wildlife science has traditionally relied on human observers in airplanes, helicopter, or ground vehicles to count the number of individuals seen during wildlife surveys. However, these traditional surveys of wildlife require significant resources, are difficult to conduct quickly and safely over remote and/or extensive locations, are disruptive to the studied species, and are prone to significant error due to unobserved or missed animals and multiple counts of single animals. …

The Deepwater Horizon Oil Spill Disaster: A Graphical Assessment Of Its Impact On Wildlife, Anvar Suyundikov

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Deepwater Horizon oil spill occurred in the Gulf of Mexico on April 20, 2010. Considered the largest accidental marine oil spill in history, oil flowed for three months and approximately five million barrels of oil spilled through by mid-July 2010. In this report, we analyze fish and bird data to assess the impact of the oil spill on the Gulf wildlife. Our findings based on the available fish data for 2005, 2006, and 2010 are not very helpful to make a judgement on the negative impact of the oil spill on fish species. On the other hand, the bird …

Do Fee-Access Hunting Programs Conserve Wildlife Habitat? A Case Study Of Utah's Cooperative Wildlife Management Unit Program, Adam L. Perschon

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Landscapes in the American West are undergoing dramatic changes as land-use patterns shift to accommodate the region’s explosive population growth. Trends toward low-density settlement patterns, or exurban development, compound the problem by consuming a disproportionately large amount of land compared to the population they support. The result is the rapid conversion of the West’s most highly productive agricultural and range lands, many of which provide benefits to biodiversity that surpass those found in permanently protected areas. Ruralists, ranchers, and conservationists alike are seeking ways to protect these ecologically important private lands from future development. One method purported to mitigate rural …

Critique Of A Wildlife Habitat Evaluation Method Applied To Residential Open Space, Sarah Rigard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To this date, little research has been done evaluating the quality of wildlife habitat provided by open space in residential areas. Quality wildlife habitat for the purposes of this study is defined as those areas which contain the physical and biological characteristics necessary to support native wildlife species of the region. This thesis critiqued a wildlife habitat assessment method used in a nationwide study of residential open space for the purpose of better understanding the research conducted by the study and to inform similar, future habitat evaluations of landscapes altered by human activity to accommodate residential land use. The methodology …

Undergraduate Honors Capstone Projects

The sagebrush grassland landscape has shaped aspects of southeastern Idaho culture and enhanced its rural economy. Sharptail grouse, sage grouse and mule deer hunting are deeply rooted in family traditions. Each fall thousands of residents head out into the field to hunt, camp and enjoy the autumn outdoors. Deer hunting and associated activities generate an estimated 240 million dollars annually, in the Idaho economy. More recently, watching and photographing mule deer and other sagebrush grassland species is increasing in popularity and economic significance. But, trends in land conversion and development threaten sagebrush grassland landscapes, the wildlife they sustain, and cultural …

Limitations On Canada Goose Production At Fish Springs National Wildlife Refuge, Utah, Dorie S. Stolley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Canada geese (Branta canadensis) recently have become management problems in some areas due to overpopulation. At Fish Springs National Wildlife Refuge (NWR), managers are concerned with the opposite situation. Despite attempts to boost production, only 18 to 34 goslings of the western Canada goose (B. c. moffitti) were produced per year, from 1989 to 1993. I studied the breeding population from March to July in 1996 and 1997. Results suggest that production is limited in 3 ways: low gosling survival, low nesting success for ground nests, and low number of breeding pairs.

Gosling survival to fledging …

The Impact Of A Mountain Pine Beetle Epidemic On Wildlife Habitat And Communities In Post-Epidemic Stands Of A Lodgepole Pine Forest In Northern Utah, William E. Stone

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Natural disturbance events influence the patterns and processes in many forest ecosystems. Ecosystem management of coniferous forests in western North America requires the recognition of the importance that natural disturbance regimes have in achieving sustainable resource production and maintaining biological diversity . Mountain pine beetle epidemics have played an historic role in the succession and structure of lodgepole pine forests in this region. Their effects on wildlife habitat and communities are undocumented, but are presumed to be substantial. I sought to quantify these effects in forty 1-ha stands of monotypic, even-aged, mature lodgepole pine forest in northern Utah approximately 3-8 …

Aspects Of The Life History Of Three Catostomids Native To The Upper Colorado River Basin, Charles W. Mcada

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The distribution, abundance and life history were studied for three catostomids -- the razorback sucker (Xyrauchen texanus), the flannel-mouth sucker (Catostomus latipinnis), and the bluehead sucker (Catostomus discobolus) -- all native to the upper Colorado River basin. The razorback sucker has declined in abundance due to man's impact upon the system and it has been recommended that this species be listed as ''threatened" on the U. S. Department of the Interior's list of Threatened or Endangered species [Personal corrmunication, G. C. Kobetich, U. S. Fish and Wildlife Service, Las Vegas, Nevada]. During this investigation, …
