Summary:
Article 6 in a series of 10, this study summarizes annual sampling of macroinvertebrates at three different spatial scales (watershed, riparian, reach) over a three-year period for 60 sites within the West- and East-of-Hudson watersheds of the NYC drinking water supply area. Six sites within the Schoharie Creek watershed were included in this analysis. Water chemistry, geology and land use variables were correlated with macroinvertebrate numbers to help determine variability in communities.
