The Silence Of The Clams: Forestry Registered Pesticides As Multiple Stressors On Soft-Shell Clams., Alexandra G. Tissot, Elise F. Granek, Anne W. Thompson, Michelle L. Hladik, Patrick W. Moran, Kaegan Scully-Engelmeyer

Environmental Science and Management Faculty Publications and Presentations

Contaminants are ubiquitous in the environment, often reaching aquatic systems. Combinations of forestry use pesticides have been detected in both water and aquatic organism tissue samples in coastal systems. Yet, most toxicological studies focus on the effects of these pesticides individually, at high doses, and over acute time periods, which, while key for establishing toxicity and safe limits, are rarely environmentally realistic. We examined chronic (90 days) exposure by the soft-shell clam, Mya arenaria, to environmentally relevant concentrations of four pesticides registered for use in forestry (atrazine, 5 μg/L; hexazinone, 0.3 μg/L; indaziflam, 5 μg/L; and bifenthrin, 1.5 μg/g organic …

Planning For Future Fire: Scenario Analysis Of An Accelerated Fuel Reduction Plan For The Western United States, Alan A. Ager, Cody Evers, Michelle A. Day, Fermin J. Alcasena, Rachel Houtman

Environmental Science and Management Faculty Publications and Presentations

Recent fire seasons brought a new fire reality to the western US, and motivated federal agencies to explore scenarios for augmenting current fuel management and forest restoration in areas where fires might threaten critical resources and developed areas. To support this effort, we modeled the scheduling of an accelerated forest and fuel management scenario on 76 western US national forests. Specifically, we modeled a 10-year ramp up of current forest and fuel management that targeted the source of wildfire exposure to developed areas and simulated treatment in areas that accounted for 77% of the predicted exposure. We used a sample …

Representation Justice As A Research Agenda For Socio-Hydrology And Water Governance, Melissa Haeffner, Dana E. Hellman, Alida Cantor, Idowu Ajibade, Vinka Oyanedel-Craver, Maura Kelly, Laura Schifman, Lisa Weasel

Environmental Science and Management Faculty Publications and Presentations

We propose representation justice as a theoretical lens for socio-hydrology and water governance studies. An exploratory survey of 496 water sector employees in the United States revealed that self-identifying females felt more strongly discriminated against due to their gender and other social factors, compared to self-identifying males. Responses unveiled how macro- and microaggressions impede career pathways to leadership positions and, therefore, representation. We identify ways in which socio-hydrology can benefit from a representation justice lens by considering the following: (1) how power and politics shape the composition of the water sector and decision-making processes; (2) how available quantitative data do …

Participatory Gis Mapping Highlights Indirect Use And Existence Values Of Coastal Resources And Marine Conservation Areas, Kaegan M. Scully‐Engelmeyer, Elise F. Granek, Max Nielsen-Pincus, Greg Brown

Environmental Science and Management Faculty Publications and Presentations

Consideration of social and cultural dimensions in coastal and marine planning has increased and ecosystem services provide important framing to investigate values and priorities associated with these systems. Research efforts in coastal communities offer insights on social dimensions of ocean and coastal management decisions, but questions remain about how demographics and geographic residence affect perceptions of marine resources and management. We conducted and analyzed a public participation geographic information system (PPGIS) mapping survey of Oregon residents to capture uses and perceived values of coastal and marine areas. We measured coastal values, explored regional differences in those values, and identified a …

Socio-Ecological Perceptions Of Wildfire Management And Effects In Greece, Palaiologos Palaiologou, Kostas Kalabokidis, Andreas Troumbis, Michelle A. Day, Max Nielsen-Pincus, Alan A. Ager

Environmental Science and Management Faculty Publications and Presentations

Adapting to the growing frequency of catastrophic wildfires in Greece and mitigating their effects is a complex socio-ecological problem. We used an online survey to query more than 100 engaged stakeholders who can potentially influence possible legislation and fire management organizational reform, emphasizing civil protection agencies and research entities. We focused the questionnaire on the importance of different wildfire effects to understand which were considered negative or unacceptable, indifferent, or positive. For fire prevention, we examined the range of acceptance and views on fuel management and fire use activities that are limited in extent or not allowed in Greece. We …

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 …

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 …

Climate Change And Water Governance: Decision Making For Individual Vineyard Owners In Global Wine Regions, Erin Upton, Max Nielsen-Pincus

Environmental Science and Management Faculty Publications and Presentations

This study investigates the institutional, social, and ecological dynamics that influence regional water governance and individual vineyard owners’ decision making in global wine regions. Global wine grape production has grown steadily over the past 20 years, and climate change has emerged as a driver of transformation in wine regions resulting in a range of impacts. Changes to the climate are anticipated to accelerate in the future and present a number of challenges for wine regions; including risks to human systems, e.g., agriculture, labor, and economics, as well as ecological systems, e.g., surface and groundwater. Water is a critical resource for …

Homelessness Research & Action Collaborative Publications and Presentations

These are the preliminary results of an ongoing project.

Stories from the Outside centers the voices of people experiencing homelessness during the 2020 Oregon wildfire season. PSU’s Homelessness Research & Action Collaborative, in partnership with the Street Roots Ambassadors program, surveyed 73 people in the Portland area in June 2021. Ambassadors sought out Black, Indigenous, and Other People of Color to ensure their voices were represented as BIPOC residents are disproportionately impacted by homelessness.

Many respondents felt disconnected and left out of emergency relief efforts. These are their stories.

Overview:

The most destructive wildfires in Oregon’s history spread across the …
