Diatoms, Sand Prairies, Sphagnum bogs, Black Hawk County, Iowa
A total of 107 diatom taxa representing 22 genera was identified from four microhabitats in a northerly facing wet swale in the Mark Sand Prairie. One of these was a Sphagnum polster. Chemical analyses of water from these microhabitats showed that none exceeded 60 ppm total hardness (as CaCO3). Fifteen taxa are new records for Iowa. A brief comparison is made between the diatom flora of this site and that of another soft water site, the Sphagnum bog located in Pilot Knob Preserve (Hancock County, Iowa).
