This thesis project compared the macroinvertebrate and plant communities and the limnological features of wetlands restored through excavation and flooding with those of unaltered, reference wetlands on TNWR. I hypothesized that the reference wetlands would hold water longest and would have higher plant diversity and macroinvertebrate diversity and abundance than …
