Bird And Small Mammal Communities Of Sagebrush-Dominated Mountain Meadows: An Examination Of Meadow Characteristics As Part Of A Hierarchical, Multi-Level Study Of The Wasatch-Cache National Forest, Elizabeth Johnson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Sagebrush shrubsteppe ecosystems have increasingly garnered attention as an endangered ecosystem. Ninety nine percent of all sagebrush ecosystems are thought to have been impacted by humans, and over 50% of grassland and shrubsteppe species are believed to be in decline. Most of the research on sagebrush ecosystems has been conducted at lower elevations and in large expanses of sagebrush. A considerable amount of sagebrush is found at higher elevations, often in meadows found within a forest matrix. The role of this high-elevation habitat is poorly understood. We conducted bird, small mammal, vegetation, and soil surveys in sagebrush-dominated mountain meadows within …

Wildlife-Vehicle Collisions In Utah: An Analysis Of Wildlife Road Mortality Hotspots, Economic Impacts And Implications For Mitigation And Management, Christine A. Kassar

In the US, the roaded landscape has had serious ecological effects. We studied wildlife-vehicle collisions occurring on the 248 state routes in Utah from 1992 to 2002. We tracked trends and patterns in deer-vehicle collisions, evaluated all routes for frequency of deer kills, and identified "hotspots" (segments of road with high concentrations of collisions per mile). We found pronounced patterns: e.g., 61.15% of all collisions occurred on only 10 routes. We studied the effects of posted speed limit and annual average daily traffic flow and found that no relationship existed between traffic volume and/or posted speed limit and the number …
