Rapid Bioassessment Procedures for Rivers
In situ biological assessment of aquatic habitats are required of all states by the U.S. Environmental Protection Agency. Under a project initially funded by the Idaho Division of Environmental Quality, we developed and tested rapid bioassessment protocols for streams and rivers in Idaho. A habitat analysis component also was included. A variety of factors used to assess biological integrity were examined for their applicability to specific conditions in Idaho. The research also allowed us to establish an initial reference database for a spectrum of `least disturbed' riverine habitats and to determine if reference streams differed significantly among different ecoregions in the state. Later, with funding from the Idaho National Engineering and Environmental Laboratory, we focused on the Upper Snake River and Lost RIvers to develop functional, in addition to structural, measures of stream ecosystem health.
