Greater Sage-Grouse Response To Sagebrush Reduction Treatments In Rich County, Utah, Roger Blair Stringham
Greater Sage-Grouse Response To Sagebrush Reduction Treatments In Rich County, Utah, Roger Blair Stringham
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Management of greater sage-grouse (Centrocercus urophasianus) in the west has changed over the last several decades in response to environmental and anthropogenic causes. Many land and wildlife management agencies have begun manipulating sagebrush with herbicides, machinery, and fire. The intent of these manipulations (treatments) is to reduce sagebrush canopy cover and increase the density of grass and forb species, thus providing higher quality sage-grouse brood-rearing habitat. However, monitoring of sage-grouse response to such manipulations has often been lacking or non-existent. The objective of our study was to determine the response of sage-grouse to sagebrush reduction treatments that have …
The Influence Of Landscape And Weather On Foraging By Olfactory Meso-Predators In Utah, Rebekah E. Dritz
The Influence Of Landscape And Weather On Foraging By Olfactory Meso-Predators In Utah, Rebekah E. Dritz
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Predation by olfactory meso-predators has a large impact on avian nest success, particularly for ground-nesting waterfowl. Olfactory predators rely on odors to locate their prey. Weather conditions (e.g. wind speed, humidity, and temperature), vegetation, and landscape features affect the dissipation rate of odors and could affect the foraging efficiency of olfactory predators. I conducted 2 studies to determine if weather and landscape impact predator foraging ability and behavior: a predator survey study and an artificial nest study. The objective of the predator survey was to investigate how landscape and weather conditions interact to influence the distribution of olfactory meso-predators [e.g. …

Effects Of Waterfowl Hunting On Raccoon Movements, Shandra Nicole Frey, Michael R. Conover
Human–Wildlife Interactions
Nontarget wildlife may react to hunters with avoidance, ambivalence, or attraction, depending upon the frequency of contact and the consequences of past contacts. We studied raccoons (Procyon lotor) located within the Bear River Migratory Bird Refuge, Utah, before and during waterfowl hunting seasons to assess changes in the size of their distributions, locations, and travel distances. Raccoon distribution size did not change with the onset of hunting. Once hunting began, raccoons were located more frequently in areas with lower densities of hunters and less frequently in areas with higher densities of hunters. Raccoons also responded to the presence …
