Topic Aquatic Inverts: Benthic Index of Biotic Integrity, All Samples
Caption:  This chart shows the Benthic Index of Biotic Integrity (B-IBI), which is a combination of 10 aquatic insect metrics, for all Battle Creek Watershed Assessment sites measured in fall 2001, spring 2002 and fall 2002. This index was devised by Karr (1991) and references are taken from Ward and Kvam (2003). The highest scores (best health) are at site #007 (Digger Cr.), #063 and #026 on upper SF Digger and in Summit Creek (#001). The lowest scores (poorer health) were at sites #016 (Bailey Creek) and #019 (SF Battle). Data from Ward and Kvam (2003). See Info Links for more information.
