EPA Region 10 analyzed data collected from 104 sample sites within the Coast Range ecoregion of Washington and Oregon. The purposes of this report are: (1) describe the ecological condition of wadeable, 1st through 3rd order streams of the Coast Range Ecoregion, (2) examine the relationship between the indicators of ecological condition of these streams and indicators of ecological stressors, and (3) provide the states of Washington and Oregon with information that can assist in the development of biological criteria using fish, amphibian, and macroinvertebrate assemblage information.
