This report, EPA/600/R-06/037F, was prepared by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development (ORD). This report supplements the Guidelines for Ecological Risk Assessment (ERA) (U.S. EPA, 1998a) by addressing issues unique to ecological assessments of watersheds. Using lessons learned from watershed ERAs, the report presents guidance and examples for scientists performing watershed ecological assessments. The report also can be useful to risk assessors, watershed associations, landscape ecologists, and others seeking to increase the use of environmental assessment data in decision making.
