This report assesses how current management actions are adhering to the original mandate set by the Wilderness Act of 1964 by monitoring the five qualities of Wilderness character (untrammeled, natural, undeveloped, opportunities for solitude/unconfined recreation, and other features of value) as they pertain to this specific Wilderness area.
Climate change, wildfire, timber harvest, and land conversion alter the availability of downed wood in forests of the western United States. Numerous taxa rely on downed wood for temperature and humidity refugia, and downed wood may play a key role in enabling the persistence of climate-sensitive, low-vagility species like terrestrial...
In Oregon, outdoor recreation activities have continued to grow in popularity, as has the overall Latin@ population of the state. With the continual population increase of this ethnic group, researchers have focused on understanding their outdoor recreation habits through an environmental justice lens. This includes accessibility, affordability, and other barriers...
Small, private forestland owners own about 12% of Oregon’s forestland and have the unique ability to implement innovative forest management activities. In southwest Oregon, extreme ecological variability occurs over small spatial scales and requires fine-scale silvicultural treatments that match the precise ecological setting and management objectives of the forests in...
Wilderness character monitoring (WCM) is an interagency strategy created in 2008 in collaboration between the four federal land management agencies that manage designated wilderness (Forest Service, National Park Service, Fish and Wildlife Service and Bureau of Land Management) and other contributors (Landres et al. 2008a). The reports created from this...
Mathematics outreach typically consists of community events that show the exciting applications of mathematics, particularly to K-12 students. The goal of mathematics outreach events is to increase student interest and involvement in mathematics-related activities. Students start to develop a stigma against mathematics by the end of elementary school. Outreach events...
Ocean Drifters are a low-cost and easy-to-use platform that are commonly used for studying ocean currents. With added interest in studying the ocean, emphasis has been taken to make it more accessible. A pilot course focused on introducing the topic of ocean sensing was announced.

Research overwhelmingly suggests that Black and Brown students face unjust and inequitable environments in K-12 schools in the United States (Bradshaw et al., 2010; Carter et al., 2017; Coles & Powell, 2020). These injustices often occur as a result of systemic racism and are replicated because of embedded racist policies...
Organic vegetable growers rely on legume cover crops as an economical source of plant-available N. This research evaluated N contributions to summer vegetable crops by cover crops (CC) residues by monitoring soil nitrate (NO3-N) concentrations during the summer crop growing season. Replicated field plots were established with three CC mixes:...
The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El Niño. Since then, numbers...
This thesis explores the mechanical properties of hemp fiber reinforced polylactic acid (PLA) composites. Fused filament fabrication (FFF) was used to compare the performance of three different weight percentages of hemp fiber reinforced PLA against PLA and acrylonitrile butadiene styrene (ABS). It was found that as the weight percentage of...
To investigate the viability of staging hydraulic air compressors (HACs), a model for HACs operating with a closed loop water cycle powered by a pump was made. This model was used to simulate how these HACs would respond to variable heights and mass flow ratios for both single-stage and multi-stage...

However, there is a lack of published research using statistically designed experiments which can aid content creators in making and...
Fusarium proliferatum is a fungus found in soils which produces the mycotoxin group known as fumonisins. Of human concern due to hepato-, nephro- and neurotoxicity, the threat of fumonisins lies within several food items, including corn, wheat sorghum, asparagus and, more recently, garlic. Manifesting as ““garlic rot”,” F. proliferatum infection...
Xanthomonas hortorum pv. carotae (Xhc) is an epiphytic, plant pathogenic bacterium that causes the disease bacterial blight of carrot (Daucus carota subsp. sativus). Infection with Xhc can result in blighting of leaves and umbels and reduce quality and yield of carrot seed crops. Carrot production in the United States approaches...

The World Trade Center disaster brought into focus, tragically, the need for well-designed evacuation systems in modem buildings. Today, designing an efficient evacuation system has become an integral part of designing large buildings. Simulation software enables an evacuation system to be evaluated. Modern day buildings, whether airports, auditoriums, public office...
Generative programming is a paradigm that seeks to automate the manufacture of software products the same way other industries automated the manufacture of consumer, electric, and mechanical products. I examine how meta-programming fits into the context of generative programming and, along the way, expose theoretic and taxonomic deficiencies. In some...
Interconnection Networks have been used as a high performance communication fabric in parallel processor architectures. Parallel processors built using off-the-shelf components, called clusters, are becoming increasingly attractive because of their high performance to cost ratio over parallel computers.
