ASSESSING MACROINVERTEBRATE COMMUNITY RESPONSE TO RESTORATION OF BIG SPRING RUN: EXPANDED ANALYSIS OF BACI SAMPLING DESIGNS
Benthic macroinvertebrates are commonly used to determine the success of stream restoration projects. The Big Spring Run (BSR) restoration project achieved its hydrogeomorphic (abiotic) goals, but macroinvertebrate community recovery was not a primary goal of the project. We examined the effect this novel restoration project had on the macroinvertebrate community, which included an assessment of potential aerial migrants and an analysis of different approaches using a BACI design to assess restoration success. Benthic macroinvertebrates were collected each year for two years prior to and three years after restoration. Adult stream insects were collected in the final year of monitoring. Subsets of the macroinvertebrate data were analyzed to supplement conclusions made from the full dataset and to characterize differing conclusions from common sample designs. Results using the overall dataset suggested that restoration had no effect on the macroinvertebrate community. The “wet meadow” created for this restoration successfully increased sediment retention and likely retained poor benthic habitat condition. Immigration was likely constrained by a lack of regional source populations and dispersal barriers, but constrained immigration was not a primary deterrent to community recovery.
