Topic	Aquatic Insects: Mark West Creek Reaches EPT Taxa 1995-1996

 

Caption:  The California Department of Fish and Game conducted aquatic invertebrate studies of several Russian River tributaries that were recognized as having sufficient biological health to support salmonids. This chart shows the average number of mayfly (Ephemeroptera), Stonefly (Plecoptera) and Caddisfly (Trichoptera) species found in four reaches of Mark West Creek in 1995 and 1996. Three samples were taken at each location but values were averaged to attain the scores listed above. This EPT Taxa index gauges health by the diversity of these pollution intolerant Orders. The reference values on the chart are those chosen by Harrington (1999) and indicate that the health of lower Mark West Creek is impaired (reaches 1-4). Note that the KRIS IFR project has added qualitative labels to these references to increase understanding of non-specialists but Harrington (1999) recommended use of all metrics in combination to judge aquatic health (Russian River IBI). See InfoLinks for more information.
