by

Ryan C. Hampton

June 2023

Windblown snow bedforms (WBSBF) are formations of distinct sizes, shapes, and patterns, resulting from the interaction of wind and snow particles. Due to the extreme nature of the formation of WBSBF, which occur in remote high elevation mountain environments during severe weather events, it makes it difficult to not only study these dramatic formations in real time but also predict their occurrence with any regularity. The purpose of this research was to 1) establish a method to actively monitor WBSBF …

Monitoring Whitebark Pine Stand Health In The Central Washington Cascades, Nancy H. Parra, Teresa J. Lorenz, Taza D. Schaming, Alison Scoville

Student Published Works

Whitebark pine (Pinus albicaulis) plays a vital role in colonizing newly disturbed areas, providing shade for other tree species to germinate, and supplying food for a variety of birds and mammals, such as Clark’s Nutcrackers (Nucifraga columbiana) and grizzly bears (Ursus arctos horribilis). Decline of whitebark pine populations has been attributed to several factors, including white pine blister rust (Cronartium ribicola), mountain pine beetle (Dendroctonus ponderosae) outbreaks, and fire exclusion. In 2009, the U.S. Forest Service began to install permanent plots in whitebark pine stands in Washington and Oregon as …

An Ecological Comparison Between Resource Subsidies: Pacific Lamprey (Entosphenus Tridentatus) And Pacific Salmon (Oncorhynchus Spp.), Jocelyn Wensloff

All Master's Theses

Historically, oligotrophic Pacific Northwest (PNW) streams received annual returns of spawning anadromous fish that provided resource subsidies in the form of marine-derived nutrients (MDN), thus driving stream food web productivity. To date, many studies in the PNW have focused on Pacific salmon (Oncorhynchus spp.) as a resource subsidy, overlooking other anadromous fish species such as Pacific lamprey (Entosphenus tridentatus). Both Pacific salmon and Pacific lamprey are culturally important to PNW tribes for ceremonial, medicinal, and subsistence purposes, and have been since time immemorial. Unfortunately, both salmon and lamprey populations are in decline. Historically, lamprey have been disregarded …

In the Yakima Basin, managers are expanding reservoirs including Cle Elum Lake to increase the availability of water. The objective of this study was to examine areas prone to further shoreline erosion to inform resource management. This research included the use of airphotos and fieldwork to identify erosional shorelines. Erosion was verified in the field using a video survey as well as indicators such as shoreline slope, sediment size, and nearshore width. Near-term erosional segments were identified by more rapidly receding bluffs while long-term erosional segments included both bedrock cliffs and bluffs. Although most of the shoreline is depositional, near-term …

Comparing Rusle Ls Calculation Methods Across Varying Dem Resolutions, Amanda Moody

All Master's Theses

Soil erosion is a global problem that reduces land productivity and causes environmental degradation. Soil erosion models, such as the Revised Universal Soil Loss Equation (RUSLE), are used to estimate the severity and distribution of erosion. The topographic factor (LS), which combines slope length and angle, is an important part of RUSLE. This work compared two methods of L calculation, the grid cumulation (GC) and the contributing area (CA) methods, and two methods of S calculation, the neighborhood (NBR) and maximum downhill slope (MDS) methods. These were compared across digital elevation models (DEMs) of 1, 5, 10, and 30m resolutions. …

Holocene Fire History Reconstruction Of A Mid-Evaluation Mixed-Conifer Forest In The Eastern Cascades, Washington, Zoe Rushton

All Master's Theses

Fire histories of mid-elevation mixed-conifer forests (MEMC) are uncommon, particularly in the eastern Cascades of Washington. As a result, fire regimes and the effects of 20th century fire suppression in these forests are not well understood. In the summer of 2014 a 7.80 meter-long sediment core was extracted from Long Lake, located approximately 45 km west of Yakima, WA, which exists in a grand fir-dominated mixed-conifer forest. Fire activity for the Long Lake watershed was reconstructed using macroscopic charcoal analysis and pollen analysis was used to reconstruct vegetation change through time. Charcoal results show low fire activity in the early …

Identifying The Effects Of Land Use And Policy On Disturbance Regimes In The Teanaway Community Forest, Washington, Savannah Bommarito

All Master's Theses

The historic fire regime of the forests of the Eastern Cascades, Washington, has been described as one of high-frequency, low-severity fires using fire scar analysis. Over the past few centuries, the historically open, park-like ponderosa pine-dominated stands have been significantly altered due to Euro-American land use change such as fire exclusion, grazing, mining, and logging. The eventual encroachment of shade-tolerant species has resulted in a high-density forest structure that promotes rare, but extreme fire behavior and heightened susceptibility to insect attacks. As a result, the current disturbance regime is significantly less frequent and of higher severity, posing risks to forest …

Ground-Truthing Social Vulnerability Indices Of Alaska Fishing Communities, Anna Lavoie, Kim Sparks, Stephen Kasperski, Amber Himes-Cornell, Kristin Hoelting, Conor Maguire

All Faculty Scholarship for the College of the Sciences

Community vulnerability is increasingly evaluated through quantitative social indices, typically developed using secondary data sources rather than primary data collection. It is necessary to understand the validity of these indices if they will be used to inform policy and decision making. This paper presents a ground-truthing effort to validate quantitative indices that characterize the well-being of Alaska fishing communities. We utilized ethnographic data collected from 13 representative communities and a capital assets framework to ground-truth the indices, in which qualitative ranks of vulnerability were compared against quantitative indices. The majority (73.8%) of ranks were in complete or moderate agreement and …

Abandoned Mine Land Impacts On Tributaries In The Upper Yakima River Watershed, Eastern Cascades, Washington, Scott Kugel

All Master's Theses

Effluent from abandoned mine lands (AMLs) in several drainages in Washington’s Eastern Cascades flows into the Yakima River. Similar sites in Idaho and Colorado are known producers of heavy metals and acid mine drainage. I determined the effects of nine AMLs on water quality in four tributaries to the Yakima River. Archival work was conducted to determine sites that were mined and contained a mill. Each site was characterized by physical features. Water and sediment samples were collected above, at, and below each AML. Samples were analyzed for pH and heavy metal content, and evaluated to determine if the AMLs …

Two Post-Glacial Sagebrush Steppe Fire Records At The Wildland-Urban Interface, Eastern Cascades, Washington, Dusty Pilkington

All Master's Theses

Recent increases in large fires in the rapidly developing wildland-urban interface (WUI) areas of central Washington, where development intermixes with wildland fuels, contribute to federal firefighting costs exceeding of $1 billion annually. In addition, cheatgrass (Bromus tectorum) invasion and anthropogenic-caused warming shorten fire return intervals while lengthening fire seasons. These climatic, ecological, economic, and social factors combine with fuel accumulation resulting from historic fire suppression to threaten lives and property in the WUI. To plan for safe growth in WUI areas, long-term fire histories are needed to expand understanding of past fire regimes in an understudied ecosystem, sagebrush …

Geomorphic Consequences Of Hydroelectricity And Transportation Development Near Celilo Falls, Lower Mid-Columbia River, Washington, Noah I. Oliver

All Master's Theses

Along the Columbia River, hundreds of miles of transportation infrastructure and over sixty hydroelectric dams have been constructed. This altered a rich cultural landscape with evidence of 10,000 years of continuous occupation. Researchers have attempted to understand the impacts of anthropogenic factors on the Columbia River, focusing on the riverine environment. However, the effect of transportation and hydroelectricity developments to eolian landforms on the floodplains and adjoining slopes have not been studied. Focusing on 2,800 acres near Celilo Falls, this study 1) establishes a baseline condition of eolian landforms from 1805 to 1900; 2) conducts an air photo increment analysis …

All Master's Theses

In 2011, Ellensburg, Washington was labeled by the Washington Department of Ecology as being vulnerable for violating National Ambient Air Quality Standards for particulate pollution (PM_2.5­). In the Kittitas Basin, winter-time frequent air inversions and stagnant air events trap pollution near the ground, elevating pollutant concentrations during winter months. Wood smoke from household burning has been identified by mobile PM_2.5 monitoring completed in 2015 as the primary source of PM­_2.5. This research utilizes community-based social marketing techniques to encourage behavioral change for wood burning in a targeted neighborhood in Ellensburg. Residents of the target neighborhood …

The Life Cycle Of Dams: An Analysis Of Policy Change On The Rogue River, Oregon, Wendy Mcdermott

All Master's Theses

Every river system contains a unique set of attributes including biophysical characteristics, human created infrastructure, and stakeholder user groups. This thesis utilizes Lowry’s (2003) “Theoretical Framework for Policy Changes” to provide an analysis of fundamental policy change that occurred on the Rogue River in southwest Oregon through a comparative case study of the removal of two dams: Savage Rapids Dam (SRD) and the Gold Ray Dam (GRD). Fundamental change occurs when political receptivity is high and physical complexity is low. Political receptivity characterizes how decisions are made and physical complexity refers to how complicated implementing the decision may be. Application …

The Role Of Fire In Montane Forest Environments In The Willamette National Forest, Oregon, Tamara G. Cox

All Master's Theses

High-resolution charcoal and pollen analyses were used to reconstruct a 16,000-year-long fire and vegetation history of the Blair Lake watershed in the Willamette National Forest of Oregon. The record shows that during the late glacial period, overall fire frequency was relatively low. Pinus and Abies were the dominant vegetation, along with Pseudotsuga and Alnus, suggesting that an open-canopy conifer forest developed soon after the area was glacier free. Fire frequency increased during the early Holocene. Warmer and drier conditions are reflected in the herbaceous vegetation, Artemisia, Poaceae, and Cyperaceae, suggesting that meadows or other openings were part of …

Eastern Washington Wildfires: Tracking Land Recovery In The Colockum Tarps Wildfire Area, Michael Balda, Allison Shinn

Symposium Of University Research and Creative Expression (SOURCE)

Eastern Washington State has seen an increase in wildfire activity because of policies of fire suppression and changing climate. The Colockum Tarps wildfire started on July 27, 2013, in Malaga, Washington, due to a water pump malfunction. After ignition, the fire quickly moved south-southwest and burned a total area of 80,408 acres of grasslands and forest. We combined fieldwork and geospatial analysis of aerial photography and satellite imagery to examine vegetative recovery within the fire area. Using ArcGIS and PCI Geomatica, we analyzed 2013 National Agricultural Imaging Program (NAIP) images and a wildfire perimeter shapefile from the Bureau of Land …
