Proceedings from a workshop on ecological carrying capacity of salmonids in the Columbia River Basin: Measure 7.1A of the Northwest Power Planning Council's 1994 Fish and Wildlife Program. Final report, report 3 of 4

摘要

This report contains the proceedings of a workshop held during 1995 in Portland, Oregon. The objective of the workshop was to assemble a group of experts that could help us define carrying capacity for Columbia River Basin salmonids. Based, in part, on the information we learned during the workshop, we concluded that the approach inherent in 7.1A will not increase understanding of ecology, carrying capacity, or limiting factors that influence salmon under current conditions. Measure 7.1A requires a definition of carrying capacity and a list of determinants (limiting factors) of capacity. The implication or inference then follows that by asking what we know and do not know about the determinants will lead to research that increases our understanding of what is limiting salmon survival. It is then assumed that research results will point to management actions that can remove or repair the limiting factors.
