Abstract Benthic macroinvertebrates are the group of organisms most widely used for assessment of water resources. Also, most of reference sites were located within the Han River watershed due to geographical bias of the sampling sites in the program (, Metric selection was performed on the basis that impaired sites supported less taxa richness and abundance than reference sites, because of unsuitable habitat conditions resulting from anthropogenic disturbance [, Taxa richness is one of the most reliable indicators in most multimetric indices, and shows good responsiveness to human disturbance [, The metrics related to the proportional abundance of taxon to the whole community are alternative measures of community balance [, Commonly used community indices were considered as composition measures, among which “Shannon’s diversity index” was found to be the most suitable. Altitude was determined using a digital elevation model (DEM), and for each sampling site a topographic map (1:50,000) was used to qualitatively characterize the watershed according to the proportions of forest, agriculture and urban land use categories.

Because of their wide distribution and distinct ecology, the assessment of stream macroinvertebrate communities has become a well-established method used by various countries to monitor waterways (e.g., references in [, Not until early in the 21st century (2006) was there a major shift of water management policy concerning stream health and ecological restoration of disturbed streams in Korea, following which various biological monitoring methods have been developed based on diatoms, macroinvertebrates and fish [, A multimetric index integrates information from a variety of ecological measures that respond to human influence in a predictable way [, For example, the Ohio Environmental Protection Agency (OEPA) in the U.S. currently uses the invertebrate community index (ICI) as its principal tool for assessing streams in Ohio [, The selection of appropriate reference sites is a critical step in developing a multimetric index because this facilitates comparisons between reference and impaired sites [, It was difficult to find reference sites for this study from the NAEMP database, despite the large number of sampling sites included. Future research will refine the constituting metrics of the index, and thereby to improve its sensitivity and robustness. Using this rationale, the metric percent of EPT individuals was chosen instead of either percent Ephemeroptera or Trichopteran individuals because of its greater sensitivity and its common use worldwide [, The remaining eight metrics of the initial 34 candidates met the first (variability) and second (redundancy) criteria, and all clearly distinguished reference and impaired sites (, All eight metrics were significantly correlated with environmental variables (, The scoring criteria for each metric were effectively determined using threshold values from reference sites (, No evidence or minor problems of anthropogenic disturbance with optimal habitat quality, Desirable biological integrity comparable to the reference condition, High species diversity and dominance by pollution-intolerant taxa, Rhithrophilic species dominated with heterogeneous coarse substrates, Low levels of disturbance impacts on communities and their habitats, Trivial increases in abundance of non-insect taxa, Slight increases in pollution-tolerant taxa but intolerant taxa still dominated, Species diversity somewhat below expectation, Significant impacts of anthropogenic disturbance on assemblages and habitat quality, Noticeable decreases in taxa richness and abundance, Evident increases in proportion of non-insect individuals and dominance of a dominant taxon, Moderate changes in assemblages from pollution-intolerant to pollution-tolerant taxa, Severe disturbance and deterioration in habitat quality, Severely impaired and unsatisfactory biological integrity, Only a few pollution-tolerant taxa present in large numbers, Potamal species dominated with homogeneous fine-sized substrates, The multimetric index was able to discriminate the reference and impaired site groups (, The multimetric index showed good responsiveness to all environmental factors, as evidenced by significant statistical correlations (, The first three PCA axes explained 80.8% of the inter-site variance, with eigenvalues >1.
