CURRENT RAPID BIOASSESMENT PROTOCOLS DO NOT ADEQUATELY ASSESS BENTHIC INVERTEBRATE ASSEMBLAGES FROM A STREAM WITH RESTORED HYDROLOGY: A CASE STUDY FROM EASTERN KENTUCKY, USA

The need for biological monitoring following stream restorations is well established, but there is no consensus regarding field methods and which biological endpoints to report. We monitored and assessed the invertebrate assemblages from a stream with restored hydrologic functions using two approaches: (1) seasonal, habitat-specific quantitative collections that began during the 2nd post-restoration year and continued through the 6th post-restoration year, and (2) a rapid bioassessment (following Kentucky Macroinvertebrate Bioassessment Index protocols) during the 4th post-restoration year. A nearby, un-restored control stream was used for comparison. Both streams drain forested watersheds (2 – 3 km2) within the Daniel Boone National Forest of eastern Kentucky. Results from quantitative monitoring revealed greater invertebrate density and biomass from the restored stream. Notably, EPT biomass from pools was 2 – 4X greater than amounts from the unrestored stream throughout the study. In contrast, the rapid bioassessment indicated no difference between streams (each stream received a ‘good’ narrative rating). These findings suggest that considering new sampling designs and metrics may improve our ability to capture the functional capacity of benthic assemblages from streams with restored hydrology.
