Biological Criteria: Technical Guidance for Streams and Small Rivers. RevisedEdition

摘要

The goal of this document is to help states develop and use biocriteria forstreams and small rivers. The document includes a general strategy for biocriteria development, identifies steps in the process, and provides technical guidance on how to complete each step, using the experience and knowledge of existing state, regional, and national surface water programs. This guidance document is designed primarily for water resource managers and biologists familiar with standard biological survey techiques and similarity familiar with the EPA guidance document 'Rapid Bioassessment Protocols for Use in Streams and Rivers; Benthic Macroinvertebrates and Fish' (PB95-194759).
