The Angler As Environmentalist: Oregon Trout And The Fight To Save The Wild Salmon Of The Columbia River, John P. Rosenberg

Dissertations and Theses

This paper traces the history of Oregon Trout, an environmental organization in Portland, Oregon, from its beginning in the fall of 1983 through the spring of 1990, when it filed petitions on behalf of four stocks of Columbia and Snake River salmon under the Endangered Species Act. It focuses on Oregon Trout's efforts to preserve the wild salmon of the Columbia River as a contemporary example of anglers acting as environmentalists to conserve threatened or endangered species. According to historian John Reiger in American Sportsmen and the Origins of Conservation, hunters and anglers have been acting in this role …

Flotation Data Sampling Strategies In Archaeological Research: An Experiment At The Elam Site (20ae195), Allegan County, Michigan, Brian David Deroo

Masters Theses

Studies of prehistoric Native American subsistence patterns have benefited greatly from data recovered through the technique of flotation, which allows investigators to recover small scale organic remains which would otherwise be missed using standard excavation procedures. Using data recovered through flotation researchers have been able to more fairly evaluate the role of plant foods, both wild and cultivated, in the aboriginal diet.

A common method of obtaining a flotation sample is to define a column through the center of the cultural feature or midden and removing a specified volume of soil matrix (usually 10 liters) from this column. This thesis …

The Paleoethnobotany Of Schwerdt (20ae127): An Early Fifteenth Century Encampment In The Lower Kalamazoo River Valley, Gregory R. Walz

Masters Theses

Carbonized macrobotanical remains from the Schwerdt Site, an Upper Mississippian sturgeon fishery in the Lower Kalamazoo River Valley are identified and analyzed in terms of their implications for localized subsistence-settlement systems operating during the Berrien Phase in southwestern Michigan. The exploitation of wild plant foods at this limited-activity, spring sturgeon fishery and the environmental composition of the site environs are reconstructed from their representation in flotation samples derived from excavated feature and midden contexts.

Botanical data indicate a strong wetland-aquatic orientation in plant procurement, with aquatic tubers being the primary plant resource exploited at the site. Data from several sites …
