Classifying Oregon Lake-Watershed Ecosystems For Regional Water Resources Assessment, Randall Alan Jones

Dissertations and Theses

Natural lake-watershed ecosystems in Oregon compose a diverse and valuable assemblage of land and water resources. With an increasing demand on lakes for recreation, water supplies, and aesthetic values and an increase in available data on Oregon lake systems, there is a need for applicable and timely scientific water management information about lake conditions statewide. This thesis is an attempt to summarize some of the data collected on natural Oregon lake-watershed ecosystems.

The purpose of the thesis is to identify the most typical natural systems out of an initial data base of twenty-four variables, measured over ninety-eight lake-watershed ecosystems. The …

Structural Analysis Of The Pacific Northwest Lumber And Plywood Industries, James G. Strathman, Anthony M. Rufolo, M. Hossein Haeri

Center for Urban Studies Publications and Reports

The lumber and plywood industries in the Pacific Northwest were particularly affected by the 1979-1982 construction recession. A subsequent recovery in output has occurred, but employment levels have remained relatively depressed. The potential for a planned reduction in the amount of timber sold from the national forests in the region also exists, giving rise to some uncertainty about the future prospects for these industries. This paper identifies the major structural factors affecting the performance of lumber and plywood producers in the region. It then proceeds to develop and simulate a set of alternative scenarios covering the 1986-1990 period to examine …
