Riparian Bird-Habitat Association Models: A Framework For Informing Management And Developing Restoration Guidelines In Utah, Hillary M. White
Riparian Bird-Habitat Association Models: A Framework For Informing Management And Developing Restoration Guidelines In Utah, Hillary M. White
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Approximately 75% of the avian species in Utah use riparian habitats at some time during their life cycles and at least 80% of this habitat in Utah has been lost or altered since settlement; currently 0.6% of land cover in Utah is considered riparian. In 1992, with the support of Utah Partner's in Flight, the Utah Division of Wildlife Resources began a statewide neotropical migratory bird (NTMB) and habitat monitoring program to assess the status of bird populations at 31 sites. Additional sites (up to 52) were added in later years; bird and habitat assessments at 37 riparian sites have …

We tested the accuracy of an invasive aquatic plant risk assessment system in the United States that we modified from a system originally developed by New Zealand’s Biosecurity Program. The US system is comprised of 38 questions that address biological, historical, and environmental tolerance traits. Values associated with each response are summed to produce a total score for each species that indicates its risk of invasion. To calibrate and test this risk assessment, we identified 39 aquatic plant species that are major invaders in the continental US, 31 species that have naturalized but have no documented impacts (minor invaders), and …
Multiscale Effects Of Forest Roads On Black Bears (Ursus Americanus), Benjamin S. Jimenez
Multiscale Effects Of Forest Roads On Black Bears (Ursus Americanus), Benjamin S. Jimenez
Graduate Student Theses, Dissertations, & Professional Papers
As the vast network of roads continues to expand across the continent, so too does the necessity to understand the associated ecological effects. To appropriately assess the impacts of these roads on wildlife it is necessary to evaluate how they affect ecological processes at multiple spatial and temporal scales. In particular, where hunting is associated with road access, roads may induce heightened behavioral responses. I assessed the effects of forest roads on habitat selection and activity patterns of a population of black bears (Ursus americanus) in the Coeur d’Alene Mountains of northern Idaho, USA. This black bear population is exposed …
