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