Abstract
Riverine health can be approximated using abundance and diversity of macroinvertebrates. Abundance of sensitive and not sensitive macroinvertebrates and their biodiversity on artificial and natural substrates was measured at Rice Creek Field Station. There are significantly more non-sensitive macroinvertebrates than sensitive macroinvertebrates (p=<0.0001). Diversity of macroinvertebrates are poor and significantly different between substrates (p=0.04). Abundance of macroinvertebrates are significantly lower in wood chip and plastic substrates (p=0.03).
