Bear Creek Watershed: Site B Data
Below are three tables that contain data collected at Site B in Bear Creek Watershed.

Table 1. Biological data collected at Site B in Bear Creek Watershed.

 Parameter

 Value

Ephemeroptera 293 individuals/m2
Plecoptera 156 individuals/m2
Trichoptera 248 individuals/m2
Coleoptera 904 individuals/m2
Diptera: Chironomidae 2168 individuals/m2
Other Diptera 79 individuals/m2
Megaloptera 3 individuals/m2
Crustacea 131 individuals/m2
Annelida 310 individuals/m2
Mollusca 0 individuals/m2

For an explanation of these parameters and the calculations that can be performed on these data, see the "Biological Assessment" section of the "Water Quality" puzzle piece. Using the data in Table 1 above, calculate the total number of organisms, EPT Index, and species diversity at Site B in Bear Creek Watershed.
