This paper provides a brief introduction to fundamental issues for watershed and regional assessments and identifies the needs for physical, chemical, and biological monitoring and research to be designed and integrated to support such assessments. Regional management requires organizing paradigms or conceptual models, and an assessment framework can serve this purpose; risk assessment is used as an example. Spatial scale (watersheds and ecoregions) can also serve as a strong organizing paradigm for management The role of federal and state monitoring and assessment programs is discussed with examples for biomonitoring. The two classes of biomonitoring methods are discussed: ecological surveys and …

Description
This paper provides a brief introduction to fundamental issues for watershed and regional assessments and identifies the needs for physical, chemical, and biological monitoring and research to be designed and integrated to support such assessments. Regional management requires organizing paradigms or conceptual models, and an assessment framework can serve this purpose; risk assessment is used as an example. Spatial scale (watersheds and ecoregions) can also serve as a strong organizing paradigm for management The role of federal and state monitoring and assessment programs is discussed with examples for biomonitoring. The two classes of biomonitoring methods are discussed: ecological surveys and toxicity testing. Biological criteria can provide an appropriate reference for monitoring and assessment and can establish statistical and ecological (practical) significance. This paper is based on Chapter 5 of Water Environment Federation`s new book, Biomonitoring, in the Water Environment.
