Invasive Species Management Plan For Oswego Lake, Daniel Warren, Mark Sytsma Jul 2009

Invasive Species Management Plan For Oswego Lake, Daniel Warren, Mark Sytsma

Environmental Science and Management Professional Master's Project Reports

This Invasive Species Management Plan defines an overarching strategy for the Lake Oswego Corporation (LOC) to mitigate threats from invasive species to Oswego Lake. Invasive species pose a direct risk to recreational and aesthetic uses of the lake, critical LOC infrastructure, and ecological communities within the lake. The Plan is particularly concerned with two bivalve mollusks in the genus Dreissena: the zebra mussel (Dreissena polymorpha) and the quagga mussel (Dreissena bugensis). These mussels grow in dense colonies that damage watercraft and underwater structures as well as displace native species. A recent scientific report found that …


Preliminary Study Comparing Precipitation Quality Between Nominal Land Uses In Portland, Oregon, Lacey Sullivan Jan 2005

Preliminary Study Comparing Precipitation Quality Between Nominal Land Uses In Portland, Oregon, Lacey Sullivan

Environmental Science and Management Professional Master's Project Reports

The purpose of this study is to analyze the precipitation quality in various land use categories throughout Portland. Because of its significance in the removal of atmospheric pollutants, wet deposition is an important component to study. In addition to its significant role in cleansing the atmosphere, wet deposition can have a direct impact on the ecosystem due to its potential pollutant load. Various land uses may provide different emission sources, each uniquely affecting the composition of the atmosphere. A literature review found few studies comparing precipitation quality between local land uses within an urban area. Wet deposition studies seem to …
