BIOLOGICAL METRIC DEVELOPMENT FOR THE ASSESSMENT OF NONPOINT POLLUTION IN THE SNAKE RIVER ECOREGION OF SOUTHERN IDAHO, 1990-91 FINAL REPORT
Description:
The purpose of this project was to develop and test a biological assessment program for representative streams in the Snake River Basin ecoregion of southern Idaho. A habitat analysis component was included to provide an independent measure of environmental conditions. The overall goals were to 1) determine the ecological conditions found in a series of relatively undisturbed stream habitats in the ecoregion, 2) use this information to examine a variety of measures of biological integrity and determine their applicability to conditions found in the Snake River Basin ecoregion, and 3) to demonstrate the utility of the ecological assessment approach by comparing conditions in environmentally impacted streams with those in the reference streams. The reference streams were further partitioned to cover the 3 major lotic habitat types in the region: upland, lowland, and spring brook. Special effort was made to select designated stream segments of concern whenever possible. HUCs: 170501, 170402, 171601, 171602. Christopher T. Robinson and G. Wayne Minshall. April 1991.
