Abstract

Activities associated with agricultural land use intensification, one of the primary sources of anthropogenic stress to aquatic ecosystems, degrade freshwater stream health and present a significant challenge to resource managers in terms of monitoring and remediation. Biomonitoring of benthic macroinvertebrates, a common method of measuring the impact of anthropogenic stress on freshwater stream health, has been used to characterize the impact of agricultural activities. However, in order for this technique to be useful to resource managers in the protection of freshwater streams from agricultural degradation, reliable methods are needed not only to determine the impact of agricultural stress on benthic macroinvertebrate communities, but also whether agriculture best management practices (BMP's) mitigate those impacts ...
