Summary

Knowledge of relationships between land cover (i.e., land use) and abiotic and biotic features of headwater streams enhances our ability to predict and effectively assess conditions in a variety of aquatic ecosystems. We evaluated land use effects on stream condition in an Iowa watershed dominated by intensive row crop agriculture and low- intensity urban development by quantifying relationships among land cover, stream invertebrate assemblages and other stream biophysical characteristics (i.e., invertebrate habitat) at 29 sites. On average, 81%% of subbasin land cover was agricultural and 6%% of land cover was urban across study sites. High nitrate concentrations (range == 5.6––29.0 mg/L) and high relative abundance of oligochaetes [...]
