摘要

The major objectives of the 1993 coastal plain stream study were to: (1) compareacid-base chemical conditions in selected Maryland coastal plain streams from 1993 (this study) with 1992 and 1987 and (2) evaluate the ecological status during the spring, summer and fall in twenty-four acid sensitive and non-acid sensitive Maryland coastal plain streams of various size located in either predominately forested or agricultural land use areas. An index of biotic integrity (IBI) for fish was determined along with an integrated assessment of chemical and physical habitat conditions in the various study streams. Data collected during the spring, summer and fall of 1993 were compared with similar data collected during 1992 to provide estimates of interannual variability.
