Macroinvertebrate Community Analysis On Lower Hood River Before And During The Removal Of Powerdale Dam: A Baseline Study, Howard Jay Patterson
Macroinvertebrate Community Analysis On Lower Hood River Before And During The Removal Of Powerdale Dam: A Baseline Study, Howard Jay Patterson
Environmental Science and Management Professional Master's Project Reports
Powerdale Dam was an 87-year-old hydroelectric complex on lower Hood River in northern Oregon which was decommissioned in 2010. Macroinvertebrate samples were collected in 2009, before the removal process began, and in 2010, near the end of the demolition project, at one site upstream and three sites downstream of the dam. Macroinvertebrate communities were analyzed using both multi-metric (Benthic Index of Biotic Integrity [B-IBI]) and multivariate (Predictive Assessment Tool for Oregon [PREDATOR]) approaches, as well as EPT and Functional Feeding Group (FFG) analysis. All analytical approaches indicated declines in habitat quality in 2010 relative to 2009, and showed increasing impairment …

Environmental Science and Management Professional Master's Project Reports
In an attempt to successfully address and reduce contamination from toxic chemicals and other pollutants in the Oregon environment, the Oregon Department of Environmental Quality is in the early stages of developing a comprehensive agency-wide toxics reduction plan. The plan seeks to find a more efficient, sustainable approach to addressing contaminants of concern to human and ecological health. Team Toxics, a work group compromised of members from various DEQ departments, has been created to collaborate and create the framework for developing these strategies. In summer 2009, Team Toxics was in the very early stages of development, and found the need …

The Sociology Of Landowner Interest In Restoring Fire-Adapted, Biodiverse Habitats In The Wildland-Urban Interface Of Oregon's Willamette Valley Ecoregion, Max Nielsen-Pincus
Environmental Science and Management Faculty Publications and Presentations
In many parts of the world, the combined effects of wildfire, climate change, and population growth in the wildland-urban interface pose increasing risks to both people and biodiversity. These risks are exemplified in western Oregon’s Willamette Valley Ecoregion, where population is projected to double by 2050 and climate change is expected to increase wildfire risk. Restoring elements of the region’s historic fire-adapted prairie, savanna, and woodland habitats may help to reduce future wildfire risk and help conserve the region’s threatened biodiversity. We report on a mail survey (n = 939) examining the socio-demographic factors influencing private landowners’ likelihood of restoring …
