An Observational Study of the Effects of Wildfire on Hermit and Varied Thrush Distribution in the Mt. Washington Wilderness Area

Creator:: Woodrich, Samuel T.
Abstract:: The hermit thrush (Catharus guttatus) and the varied thrush (Ixoreus naevius) are focal species for conservation of forested habitats in Oregon. Although habitat associations have been defined for both species, their response to changes in vegetation following wildfire has not been well studied. To help fill this information gap, I...

Habitat Associations and Diet Composition of Western Purple Martins in Western Oregon

Creator:: Sherman, Lorelle M.
Abstract:: The western purple martin (Progne subis arboricola) is a species of conservation concern throughout the Pacific Northwest. In western Oregon, the purple martin nests in three major ecosystem types: inland open-water, coastal, and upland forest. The availability of suitable breeding habitat is a major limiting factor for western purple martin...

Created Snag Dynamics and Influence on Cavity-nesting Bird Communities over 25 years in Western Oregon

Creator:: Barry, Amy Marie
Abstract:: Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function...

Interactive effects of silvicultural herbicides and cervid herbivory on early seral plant communities of the northern Oregon Coast Range

Creator:: Stokely, Thomas D.
Abstract:: Intensive forest management (IFM, dense conifer plantings and herbicide applications) may alter the characteristics of early seral plant communities that function as major habitat resources for a host of wildlife species, including cervid herbivores such as Cervus elaphus and Odocoileus hemionus. Such large herbivores can also substantially affect plant community...

Post-breeding habitat selection by songbirds in the headwaters of the Trask River, northwestern Oregon

Creator:: Jenkins, Stephanie R.
Abstract:: Little is known on the importance of riparian areas to birds near small headwater streams in mesic forests. Progress towards understanding limiting factors that affect bird populations has been difficult because of lack of information beyond the breeding period. I compared bird assemblages between headwater riparian and upland areas throughout...

Influences of salvage logging on forest birds after fire in the eastern Cascades, Oregon

Creator:: Cahall, Rebecca E.
Abstract:: Previous research examining the influences of post-fire salvage logging on abundances of birds has focused primarily on the response of cavity-nesting species. There is limited research in regard to the impact of salvage logging on a broader range of bird species. In addition, little is known about how different intensities...

Pacific marten occupancy and detection probability in relation to infrastructure and environmental factors in the southern Cascade Mountains

Creator:: Hill, Deborah J.
Abstract:: Humans benefit from being in nature and recreating, however outdoor recreation can negatively impact wildlife, including species of conservation concern such as the Pacific marten (Martes caurina). Densities of martens decline following intensive forest management activities, but impacts from recreation are relatively unstudied. My goal was to evaluate marten occupancy...

Pacific marten occupancy and detection probability in relation to infrastructure and environmental factors in the southern Cascade Mountains

Creator:: Hill, Deborah J.
Abstract:: Humans benefit from being in nature and recreating, however outdoor recreation can negatively impact wildlife, including species of conservation concern such as the Pacific marten (Martes caurina), which has been used as a focal species for demonstrating ecosystem integrity. Marten population densities decline following intensive forest management activities, but impacts...

Determining strategies for the protection of nesting Interior Least Terns (Sternula antillarum athalassos) in Indiana

Creator:: Espick, Lainey
Abstract:: Interior least tern (Sternula antillarum athalassos) populations and productivity have been declining in Indiana for the past ten years, which is thought to be the result of predation. Methods for protecting nesting Interior least terns include fence exclosures and artificial shelters for chicks, but their effectiveness is unknown. Each Indiana...

The Use of Effectiveness Monitoring and Reporting for Fish and Wildlife Habitat Restoration Within the Collaborative Forest Landscape Restoration Program 2010-2018

Creator:: Kitayama, Eileen K.
Abstract:: The Collaborative Forest Landscape Restoration Program (CFLRP) is a collection of large-scale restoration projects across the United States that are striving to improve many economic, social, and ecological sustainability issues, including the condition of fish and wildlife habitat. Effectiveness monitoring is a specific type of monitoring that is critically important...
