Accelerated bank erosion and bank failures are common disturbances in rivers with agriculturally dominated catchments.  Increased agricultural activity in the Cedar River watershed of central Nebraska has led to the removal of riparian vegetation, increased river discharge, accelerated rates of erosion, and massive bank failures on the Cedar River.  To mitigate further erosional losses several 300-500m reaches were stabilized with jetties designed to redirect flow and create sites for sediment deposition. The objective of this study was to determine if there were differences in the macroinvertebrate and fish communities between the stabilized and unstabilzed reaches, as well as determine if the stabilization projects altered the amount and type of riparian vegetation present.  Seven stabilized sites and three unstabilized sites were sampled over the summer of 2007.  Macroinvertebrates were quantitatively sampled in May, July, and September.  Riparian vegetation cover and species identification was conducted in August and fish were collected in October.  Macroinvertebrate richness, diversity, and densities were significantly higher at the stabilized sites.  Riparian vegetation cover was significantly greater at the stabilized sites and the stabilized sites had significantly more wetland plant species.  Stabilized sites also had significantly greater fish species richness and diversity.
