Institute for Sustainable Solutions Publications and Presentations

This report presents both qualitative and quantitative survey data concerning resident perceptions of ecosystem services in Portland’s Forest Park. Focus group best practices and ecosystem services in urban parks literature are reviewed. Representative focus groups were conducted to ascertain local awareness and understanding of the urban wilderness area’s ecosystem services, identify concurrent challenges and measure interest in a potential interpretive center. Individual surveys were also administered in order to connect issues with demographics and recreational use information. Regression analyses were conducted to examine related park usage, access and economic trends.

While the study is preliminary, the results reveal opportunities for …

Age Determination Of Modern And Archaeological Chinook Salmon (Oncorhynchus Tshawytcha) Using Vertebrae, Anthony Raymond Hofkamp

Dissertations and Theses

Incremental growth rings in X-rays of salmon vertebrae have been used since the 1980s to age Pacific salmon (Oncorhynchus spp.) remains from archaeological sites in the Pacific Northwest. These age estimates, paired with generalized life history patterns, have been used to determine salmon species, season of capture and in turn season of site occupation. This approach relies on a variety of assumptions, the most fundamental of which is that rings represent true years. Archaeologists using vertebral age determination techniques have failed to adequately test this assumption and present their methodologies. This thesis assesses the validity of using incremental …
