Abstract
This paper represents a continuing multidisciplinary analysis of species preservation and global change. It explores the economic cost of a potential regional warming's effect on the spring chinook salmon (Oncorhynchus tshcawytscha). Climate change and planned habitat improvements impact the production and economic value of spring chinook salmon in the Yakima River tributary of the Columbia River in eastern Washington. A chinook salmon's total economic value includes the summation of the existence, commercial, recreational, and capital values. The analysis here applies currently available data on these four components of value to estimated changes in chinook salmon population resulting from regional warming. Results show that the estimated change in economic value per fish associated with reducing one fish run is significant.
