Abstract

The community structure of benthic macroinvertebrates in Upo wetland was identified, and the biological water quality was evaluated. In addition, through statistical analysis of current and literature data, ecological changes over time were evaluated for each wetland. Benthos were quantitatively collected in March, June, and September of 2020 and 2021, and 4 phyla, 5 classes, 16 orders, 42 families, 81 species and 3,406 individuals were identified. In the functional feeding group of Upo wetland, predators were dominant with 34 species (45.95%) and 1,504 individuals (41.84%). In the habitual dwelling group, sprawlers and swimmers showed the highest proportion in the number of species and individuals. Average biological indices in Mokpo and Upo were the highest and lowest, respectively, and it is considered that Mokpo maintains the healthy ecosystem for benthic macroinvertebrates. Community stability was high in Upo, and other wetlands are thought to be stabilizing. The ecological score of benthic macroinvertebrate community is considered to be more suitable index among three biological water quality evaluation indices for the environmental evaluation of Upo wetland. The evaluation results on changes in environmental quality showed that Upo has stable ecosystem without significant change, Mokpo and Sajipo have significant increases in some indices.
