| Topic | Aquatic Insects: Scatterplot All Freshwater Pct. Dominance 1994-98 |
| Caption: This chart shows the percentage of a sample that one species comprises, which is the Percent Dominance index, for all Freshwater Creek locations in all years sampled. Harrington (1999) characterized healthy communities as having one species comprise no more than 14% of a sample. When samples have one species that comprises more than 39%, the community is impaired (Harrington, 1999). Click on the Picture tab to see a map of monitoring locations. Data were collected by PALCO. See Info Links for more information on using aquatic insects as indicators. | |
