Summary

This Benthic Invertebrate Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the benthic invertebrates sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), the invertebrate samples were taken from sediments remaining from the sediment analysis. Identification of the invertebrates was completed by the same invertebrate taxonomist for both the 1998-2000 evaluation and 1986-87 historical evaluation (Smith et al. 1994) for increased consistency. Oligochaetes were identified to species if possible, chironomids were identified to genus, as adult specimens are needed for specific identification, and other taxa were identified as [...]

Purpose

Benthic invertebrates were sampled to ascertain relative diversity and abundance, where low species diversity and presence would indicate poor sediment and water quality. The data collected as part of the LEEI evaluations have been used to ascertain whether remedial activities and contaminant reductions had been successful for AOCs on Lake Erie. In future work, the techniques established in the LEEI reevaluation can be used to monitor trends in the Lake Erie ecosystem over the long term. The LEEI dataset can serve as a foundational data source, when used in comparison to future data collections, for analyzing the long-term success or not of contaminant reductions and impacts.
