Invert Sampling Series #1419

A sampling series is a set of benthic macroinvetebrate sessions that are used to generate an Index of Biotic Integrity (IBI). A standard series will contain 3 quantitative sessions and one qualitative session. However, sometimes quantitative replicates are lost in the field, buried, or otherwise damaged enough not to be included in a series. There may even be an extra replicate collected and included in the series. This is rare and typically only occurred during the early stages of the biological assessment program.
