    Abstract

    Species lists make up much of the historical and present-day information presented in conjunction with environmental impact assessments. Most such lists have not been analyzed to determine whether the patterns of occurrence of species are indicative of differences in water quality. Statistical procedures are proposed to determine whether patterns of species occurrence are found in the data and, if so, which samples and species appear to contribute most strongly to the observed patterns. The application of these procedures is discussed with examples.
