BMIBI Score Explained

This site was analyzed using the BMIBI-Cold Water assessment methodology.

A detailed analysis of the IBI score has not yet been determined for coldwater IBI metrics.

This location has been classified as a Reference Site. Reference sites represent natural stream qualities that are least disturbed by human activities within the watershed. These sites are then grouped by ecoregion to establish a benchmark against which other streams in the same ecoregion are compared.

EcoRegion Comparison

Scores for a sampling session are compared against reference sites within the same ecoregion:

Paleozoic Plateau (Driftless Area)

This site is in the Paleozoic Plateau (Driftless Area) ecoregion.
