Feral Swine Action Plan For Oregon, Mark Sytsma, Arick Christopher Rouhe Jan 2007

Feral Swine Action Plan For Oregon, Mark Sytsma, Arick Christopher Rouhe

Center for Lakes and Reservoirs Publications and Presentations

Feral swine are defined as free roaming animals of the genus Sus that are not being held under domestic management or confinement. Swine have spread from Europe and Russia to habitats around the world via human introduction. Currently, feral swine populations are established on every continent except Antarctica. Unlike other large mammal invaders, swine have a high reproductive capacity and are omnivorous, which allows for a quick assimilation into most habitats. Once a breeding population is established in an area, the population can quickly increase and negatively impact the ecosystem. A successful invasion of feral swine is difficult, and sometimes …

Oregon Spartina Response Plan, Mary Pfauth, Mark Sytsma, Dennis Isaacson Jan 2007

Oregon Spartina Response Plan, Mary Pfauth, Mark Sytsma, Dennis Isaacson

Center for Lakes and Reservoirs Publications and Presentations

Four introduced, invasive species of Spartina (cordgrass) have been present in estuarine areas of the U.S. west coast for over a century. These Spartina species are ecological engineers- they cause severe alternations in the hydrology and food webs of invaded estuaries that are detrimental to native wildlife and commercial and recreational uses. Oregon has been relatively free of these weeds, with only two known infestations. One infestation was eradicated by Oregon Department of Agriculture and the other is currently under eradication by The Nature Conservancy.

Using Principles Of Momentum Conservation To Develop A Coastal Storm Impulse Scale (Cosi), Chris Adam Klentzman Jan 2007

Using Principles Of Momentum Conservation To Develop A Coastal Storm Impulse Scale (Cosi), Chris Adam Klentzman

Civil & Environmental Engineering Theses & Dissertations

Coastal engineers have long recognized the need for a storm classification system that combines wave conditions, storm surge, and the length of time for the storm event. A new classification system has been developed that is based on the conservation of total horizontal momentum. This research concentrated on developing the theory and then applying that theory for a 10-year period of data from the Army Corps of Engineers Field Research Facility (FRF) in Duck, North Carolina. When fully developed, the Coastal Storm Impulse scale (COSI) may be applied to all previous Hurricane and Northeaster storm events along a coast and …
