This joint mission to protect the natural resources of the state while at the same time generating income by harvesting those resources creates a framework in which difficult management decisions must be made. The purpose of this regional risk assessment using the relative risk model RRM was to provide estimates of the historical current and future relative risks that potentially affected or will affect the Cherry Point CP herring stock as well as the surrounding region from nearby anthropogenic sources to aid WDNR in these management decisions. Moreover alternative assessment endpoints were also identified in the CP region that would provide additional information to WDNR regarding the chemical toxicological organismic and trophic interactions specific to the CP area. These additional assessment endpoints in combination with the results of the CP regional-scale ecological risk assessment will help to ensure .
