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 …
Intertidal Habitat Utilization By Endangered Green Sturgeon (Acipenser Medirostris), Willapa Bay, Washington, Luke Stilwater
Intertidal Habitat Utilization By Endangered Green Sturgeon (Acipenser Medirostris), Willapa Bay, Washington, Luke Stilwater
All Master's Theses
This study looks at a portion of the designated critical habitat for the threatened southern distinct population segment of green sturgeon (Acipenser medirostris) in Willapa Bay, Washington. Willapa Bay is an intermediate size (258.7mi2) estuary on the southwest coast of Washington State, approximately 30 miles north from the mouth of the Columbia River. Recent studies completed by the National Marine Fisheries Service have shown that significant aggregations of green sturgeon in Willapa Bay occur during the late summer months, and foraging activity for burrowing ghost shrimp (Neotrypaea californiensis) is evidenced by small round feeding pits (30-60 cm diameter) in the …
Two Post-Glacial Sagebrush Steppe Fire Records At The Wildland-Urban Interface, Eastern Cascades, Washington, Dusty Pilkington
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 …
