Viability criteria comparison essay (2008)
Viability criteria comparison table (2008)

The aim of these documents is to summarize and qualitatively compare the TRTs’ viability criteria. The essay describes why there are different viability criteria for ESA–listed salmon and steelhead, outlines the similarities and differences among the criteria, and includes tables and flow charts that graphically illustrate the criteria. The comparison table gives precise descriptions of how each TRT treats a large number of issues, addressing the differences between the methods that the TRTs used and what the differences mean.
