Abstract | Regional patterns in terrestrial characteristics can be used as a framework to monitor, assess and report the health of aquatic ecosystems. In Ohio, five ecological regions were delineated using combinations of spatial patterns in land-surface form, land use, soil and potential natural vegetation. The authors evaluated the framework by studying the water quality, physical habitat, and fish and micro-invertebrate assemblages of 109 minimally impacted representative streams. Water quality and fish assemblages showed clear regional difference. |
