  Citation × Citation Citation Abstract Copy Title: Identifying Clusters of Non-Farm Activity within Exclusive Farm Use Zones in the Northern Willamette Valley Author: Chun, Nicholas Year: 2017 This thesis provides an extensive look at where permitted non-farm uses and dwellings have clustered within Exclusive Farm Use (EFU) zones in the Northern Willamette Valley in Oregon. There is a looming concern that non-farm related uses and dwellings, or non-farm development, are conflicting with agricultural preservation strategies. Specifically, non-farm developments can potentially undermine the critical mass of farmland needed to keep the agricultural economy sustainable, but until now, studies have lacked spatially precise data to systematically track these phenomena. This thesis offers methodological contributions towards analyzing these operations and presents a broad account of what has been occurring in the region. Using permit approval data from the Department of Land Conservation and Development (DLCD) and 2015 county tax lot shapefiles, I geocoded the locations of these uses and dwellings. I used location quotient and spatial autocorrelation coefficients to identify non-farm hotspots in the region and summarized different typologies that have developed. The findings reveal that viticulture operations have amassed near Dundee and Newberg in Yamhill County, while commercial activities and home occupations have clustered near the Salem-Keizer UGB. Concurrently, dwellings have clustered near the Yamhill-Polk County border. Finally, I offer suggestions to improve Oregon's agricultural land use policy and data management process, as well as advocate for more intensive research in the future to generate narratives for our results.

  Citation × Citation Citation Abstract Copy Title: Oregon Lake Watch, 2014 Annual Report Author: Jordan, Meredith, Miller, Rich, Strecker, Angela L. Year: 2015 The Oregon Lake Watch (OLW) volunteer monitoring program is now in its second year of operation, continuing its focus on early detection of aquatic invasive species (AIS), with a secondary focus on lake water quality. The aquatic invasive species chosen as Watch List priorities for the OLW are based on the Oregon Department of Agriculture’s Noxious Weed List (Oregon Department of Agriculture Noxious Weed Control Program 2014) as well as professional judgement (more information can be found in Oregon Lake Watch Final Report 2014). This report summarizes the data collected by 15 of 24 OLW volunteers over 2014, across 110 sampling events and 20 Oregon lakes. Data collected by trained volunteers includes sightings of both native and aquatic invasive plants and animals, as well as recordings of lake temperature profiles, and Secchi depth, a measure of clarity. Of the 16 original water bodies surveyed in OLW’s first year (2013), 12 were surveyed again in 2014, and 8 are new waterbodies. Long-term monitoring of these lakes provides valuable information over time, and expanding the number of lakes monitored, especially in the case of monitoring for invasive species, means that more potentially harmful invasions can be stopped sooner. Ideally, the OLW will continue to monitor these current lakes, and expand their volunteer network to cover more waterbodies across Oregon as this program continues to grow.

  Citation × Citation Citation Abstract Copy Title: Oregon Spartina Response Plan Author: Pfauth, Mary, Sytsma, Mark, Isaacson, Dennis Year: 2007 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.

  Citation × Citation Citation Abstract Copy Title: Feral Swine Action Plan for Oregon Author: Sytsma, Mark, Rouhe, Arick Christopher Year: 2007 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 impossible, to reverse. A feral swine pest risk assessment for Oregon, released in 2004, designated feral swine as a very high-risk species due to high potential for establishment, environmental and economic impacts, and disease transmission to wildlife, livestock and humans. Economic impacts on ecosystems and disease transmission to wildlife are difficult to assess, but restoration of ecosystems and losses to agriculture and livestock have been estimated to exceed US$800 million in the United States each year. Environmental impacts include facilitation of noxious weed invasions, shifts in dominant plant species, reduction of forest regeneration, and soil erosion. Facilitation of noxious weeds and erosion due to feral swine rooting are documented in Oregon. Feral swine in Oregon have not been implicated in disease transmission to humans, but the recent E. coli outbreak from spinach grown on a California farm that caused three deaths has been genetically traced to feral swine excrement deposited in spinach fields. The feral swine population in Oregon is currently small and dispersed. Few disturbances have been documented but state and federal biologists report regular occurrence of disturbances due to feral swine. Actions to prevent the effects of an invasion fall into three categories: management, control or eradication. Of the three categories, only eradication efforts have successfully slowed or reversed the effects of swine invasions. Case studies from California, Australia, Hawaii, the Galapagos Islands and the Channel Islands off the coast of California show that management and control efforts, while effective in the short term, have not successfully kept small feral swine populations from increasing to levels that are unmanageable and uncontrollable. A four-year feral swine eradication plan is proposed. The Plan includes recommended legislative changes to facilitate eradication, outreach and education, population assessment, rapid response, and eradication elements. A 0.5 FTE position is required at the Oregon Department of Fish and Wildlife to implement the plan. Eradication of feral swine in Oregon is estimated to require a four-year, $1.29 million effort. Follow-up control of new releases and escapes will require a maintenance effort estimated at less than $50,000 per year (excluding contingency funds for emergency response). These costs are small relative to the value of the $3.6 billion Oregon agriculture and livestock industries and the investment Oregon has made in riparian restoration efforts. Sustained control of feral swine in Oregon will require a longterm commitment that will include annual domestic swine marking, education, and monitoring.

  Citation × Citation Citation Abstract Copy Title: Aquatic Vegetation in Irrigation Canals Author: Sytsma, Mark, Parker, Michael Year: 1999 Preparation of this guidance manual for integrated aquatic vegetation management in irrigation canals was stimulated, in large part, by the accidental release of acrolein-treated irrigation water into Bear Creek in southern Oregon. The resulting fish kill brought into focus the need to examine the methods available for managing aquatic vegetation in flowing water. Furthermore, it demonstrated the need for technical assistance on aquatic vegetation management in Oregon. Vegetation management in flowing water is a difficult undertaking. The interconnectedness of natural and manmade water conveyance systems, the tenuous status of many aquatic species, and the necessity of water delivery for profitable and productive agriculture in Oregon and much of the Northwest interact to focus attention on the way that aquatic vegetation management is conducted. Endangerment of fish species in the Pacific Northwest requires a detailed examination of agricultural operations. This manual is intended to provide water conveyance system managers a summary of available technologies for aquatic vegetation management and to outline the concepts and procedures necessary for development of an integrated management plan for vegetation growing in canals. With the adoption of a thoughtful approach to aquatic vegetation management, and with technical assistance and research on the problem plants and control techniques, aquatic vegetation can be managed without severe off-site and non-target impacts. It is hoped that this manual will assist in reaching that goal.
