In-Depth Information
Calculation table (use your own or provided data set). A typical FQAI does not
include abundance data, but only species presence. However, you may have
abundance data that you may want to use to weight your findings.

4. What does the FQAI tell you about the quality of the wetland site?
5. Do the mean C of C or the weighted C of C provide similar or different
interpretations to the FQAI? How are they similar or different?
