About the User Manual
This manual provides practical advice on how to calculate and interpret a SIGNAL 2 score. It includes a brief introduction to the relevance of aquatic macroinvertebrates in river and stream assessment, and some advice on sampling and identification. These matters are not treated in detail because several excellent guides on sampling and identification already exist. References are provided for those wishing to pursue these topics further.
Readers who are familiar with macroinvertebrate biology and sampling can skip the introductory sections.
