Power analysis of escapement trends for the coho salmon protocol
Starcevich L. 2008. Power analysis of escapement trends for the coho salmon protocol. University of Idaho. Moscow, ID
San Francisco Area Network (SFAN) monitors Coho salmon populations within parks located in the coastal watersheds of Marin County. Long-term monitoring projects are used to detect changes over time in attributes of the population. Power analyses of the tests of trend are useful in assessing what degree of change may be detected or the length of time needed to detect trend given the current methodology. The power to detect trends of escapement metrics is examined in this report using pilot data from 1997-2007.
