SUPPLEMENTARY INFORMATION:

I. Information About CADDIS

    Over a thousand water bodies in the United States are listed by 
states as biologically impaired. For many of these sites, the cause of 
impairment is reported as ``unknown.'' Before appropriate management 
actions can be formulated for impaired water bodies, the causes of 
biological impairment (e.g., excess fine sediments, nutrients, or 
toxics) must be identified. Effective causal analyses require knowledge 
of the mechanisms, symptoms, and stressor-response relationships for 
various stressors, as well as the ability to use that knowledge to draw 
appropriate, defensible conclusions. To aid in these causal analyses, 
NCEA developed CADDIS, which is a web-based decision support system 
that will help regional, state, and tribal investigators find, access, 
organize, and share information useful for causal evaluations in 
aquatic systems. CADDIS is based on EPA's Stressor Identification 
process, which is a formal method for identifying causes of impairments 
in aquatic environments. Features include a step-by-step guide to 
conducting causal analysis; examples and applications; a library of 
conceptual models; and an online application for collaborating on 
conceptual diagrams and using them to update and access a database of 
supporting literature, information on basic and advanced data analyses, 
downloadable software tools, and links to outside information sources.
