Biotic Index Card (macroinvertebrates)

The Biotic Index Card (BIC) is a simple tool to evaluate the overall health of a stream. Simple insect nets can be used to capture stream macroinvertebrates which can then be identified and categorized using the BIC card. The overall score produced by the BIC process will tell you the health of the stream.
