Urban Lakes: Ecosystem Services And Management, Laura Costadone

Dissertations and Theses

Lakes provide a variety of ecosystem services and benefits that greatly contribute to urban sustainability. Despite the growing interest in integrating freshwater systems into management and policy decisions, urban lakes are often overlooked in land-use planning. Nutrient and pollutant runoff from the surrounding urbanized watershed result in water quality deterioration that negatively impact the lake ecological functions and related ecosystem services. The vulnerability and degradation of these urban ecosystems should be a matter of concern, especially considering that, in rapidly growing metropolitan areas, the demand for aesthetic and recreational services provided by urban lakes is increasing. The overall goal of …

Tribal Revegetation Project Final Project Report: 92-Acre Area, Area 5 Radioactive Waste Management Complex, Nevada National Security Site, Nevada, Jeremy Spoon, Brittany Kruger, Richard Arnold, Kate Monti Barcalow, Tribal Revegetation Committee, Trc

Anthropology Faculty Publications and Presentations

Nuwu (Southern Paiute), Newe (Western Shoshone), and Nuumu (Owens Valley Paiute) are linguistically related, Numic-speaking peoples who are part of the broader Uto-Aztecan language group. Numic peoples view the land as a holistic, living, sentient being with feelings and purpose. The land is personified with human characteristics and it needs to be experienced to be understood through “learning by doing.” Numic peoples do not support ground disturbing activities within their ancestral lands, including activities tied to the storage of low-level radioactive waste or classified materials on the NNSS, which they view as culturally inappropriate. These deep-rooted ancestral connections are the …

Biological Invasions In Coastal Marine Ecosystems: How Changes In Trade Are Linked To Ballast Water Delivery Of Nonindigenous Species, Danielle Elizabeth Verna

Dissertations and Theses

Globalization has escalated transfers of nonindigenous species (NIS) across natural dispersal barriers. The resulting biological invasions have become a leading global mechanism of ecological change. NIS are often transported between coastal marine ecosystems in the ballast water of commercial ships, and patterns of NIS introduction and establishment can be linked to global trade dynamics. Here I examined drivers of trade and ballast water across spatial and temporal extents of invasion. The analyses incorporated a variety of datasets on trade, industries, and ship behavior to identify fluctuations in globally transported commodities that lead to changes in maritime shipping patterns and frequency. …

Walking As A Way Of Knowing: An Autoethnography Of Embodied Inquiry, Lauriel-Arwen Amoroso

A New Agent-Based Model Provides Insight Into Assumptions In Modeling Forest Management Under Deep Uncertainty, Garry Sotnik, Robert M. Scheller, Brooke Alyce Cassell, Matthew Joshua Duveneck

Environmental Science and Management Faculty Publications and Presentations

Context: Exploratory modeling in forestry uses a variety of approaches to study forest management questions. One key assumption that every approach makes is about the degree of deep uncertainty—the lack of knowledge required for making an informed decision—that future forest managers will face. This assumption can strongly influence simulation results and the conclusions drawn from them, but is rarely studied.

Objectives: Our objective was to measure the degree of deep uncertainty within a forest management simulation to compare alternative modeling approaches and improve understanding of when a specific approach should be applied. Methods We first developed a method for measuring …

Plastic Roads: Not All They’Re Paved Up To Be, Katie Conlon

Urban Studies and Planning Faculty Publications and Presentations

The growing, global plastic waste crisis is sparking a myriad of solutions from disparate fields. One such end-of-use solution is the application of plastic waste for paving roads. This solution is marketed as a win-win option for plastic waste, use the single-use waste material to pave roads and save money, and simultaneously tackle the accumulated plastic waste. Paving with plastic is occurring globally, but has been especially appealing in the global south contexts where waste management infrastructure is lacking, and pressure to do something about the plastic waste is high. However, there are several environmental and social considerations to paving …

Poised For Change: University Students Are Positively Disposed Toward Food Waste Diversion And Decrease Individual Food Waste After Programming, Manar Arica Alattar, Jennifer L. Morse

Environmental Science and Management Faculty Publications and Presentations

Eaters (consumers of food) are responsible for 60% of waste along the food cycle in developed countries. Programs that target individual and household food waste behavior change are essential to addressing such waste. School cafeterias worldwide offer an opportune microcosm in which to educate on food and nutrition skills and change related behavior. No Scrap Left Behind, a cafeteria food waste diversion program, was developed, piloted, and assessed based on measures of both direct and indirect food waste behavior, and attitudes, knowledge, and emotions related to food waste.

Assuring healthy streams in the urban environment is a major goal for restoration scientists, urban planners, and city practitioners around the globe. In South Korea, many urban stream restoration efforts are designed to provide safe water to society and enhance ecological functions. We examined the extent to which the individual interests and different values of multiple stakeholders were considered in previous decision-making in two urban stream restoration projects. The relevant data on stream restoration were collected through the nominal group technique (NGT) and the analytic hierarchy process (AHP) for the two stream cases of a populated inland area and a …

Book Review: Blue Infrastructures: Natural History, Political Ecology And Urban Development In Kolkata, Dana E. Hellman, Melissa Haeffner

Environmental Science and Management Faculty Publications and Presentations

What role does a river play in shaping urban justice and resilience? Jenia Mukherjee tackles this provocative question with an equally provocative answer: rivers are critical infrastructures with biophysical and social histories, both of which inform their physical condition and socio-ecological assets. In Blue Infrastructures, Mukherjee masterfully illuminates the intersection of materiality and history in the urban environment, exploring its implications for a just and resilient future city. Tracing the uses and evolution of Kolkata's “blue infrastructures”—rivers, wetlands, seas, etc.—from the colonial period to the present, Mukherjee's analysis addresses a pressing question in this era of the Urbanocene: How …

Trail Impact Monitoring In Forest Park, James Mitchell

Environmental Science and Management Professional Master's Project Reports

Forest Park is an appropriately named 5,200 acre natural area located in northwest Portland, Oregon. A recent study estimated park usage near half a million annual visits and found "trails" to be the park’s most highly valued feature. Unfortunately, many trails were not designed for such traffic as evidenced by slipping hazards, erosion and other ecological impacts. In response to these observations, I partnered with Portland Parks & Recreation to conduct an objective trail impact assessment prescribed by the Forest Park Natural Resource Management Plan. I modified methods from past studies to expand on a recently completed trail condition class …

Interests And Priorities In Sockeye Salmon Management: How Are Policies Enacted And Interpreted On Three Alaskan Rivers?, Jake P. Palazzi

University Honors Theses

The large export abundance of Alaskan salmon is well documented, and many studies have been performed to assess the economic and environmental viability of the industry and its management. Less research has been done to characterize how state intentions regarding fisheries allocation are conceived of by management or perceived by vulnerable groups in the user pool. This study seeks to qualitatively characterize the disconnect between state and Native Alaskan perceptions of management effectiveness, public interest, and Native Alaskan involvement using interviews. Results showed that Native Alaskan and state manager respondents had very different perceptions of management effectiveness and equity. When …

Effect Of Parasitic Orobanche Uniflora On Sedum Plants And The Potential Implications For Urban Green Roofs, Jessica Bigger

University Honors Theses

An increasing presence of the parasitic plant Orobanche uniflora has been observed on green roofs in urban areas such as Portland, Oregon. Although little is known about these plants, they are believed to be detrimental to host plants such as sedums that grow on green roofs. Orobanche uniflora takes over the host plant’s cellular structure and uses this to take in nutrients. This poses a problem for green roof succulents because if the host plants are killed by the parasite then the green roofs will not be able to function as effectively. Green roofs may also be contributing to an …
