Fraser River sockeye salmon: data synthesis and cumulative impacts

Given the above definitions, you should use all ratinglevels from 1 to 5. In practice, the distribution amongthese 5 values may not be completely even, due tooccasional large changes (e.g., a new pulp millconstructed that substantially changes the level ofpollution). The most important thing is to assign 1s tothe best years, 5s to the worst years and scale the valuesin between. The distribution among quintiles may onlybe approximate, but ensure that the full range of valuesis used. If you can only evaluate years as 1, 3, or 5, thatis acceptable too.Proceed to Next MetricOnce you have finished adding the data for one metric, begin with the next metric in thesubsequent worksheet.End of Guidelines272
