This study was conducted to provide basic data to verify the validity of functional evaluation items suitable for small living area wetlands, which have recently been emphasized in importance. The distribution status of ecosystem-disrupting organisms distributed in major rivers and reservoirs in Seosan-si was identified, and the basic data for functional evaluation was suggested. The conservation and restoration of riparian areas for the restoration of lateral connectivity of rivers in Seosan-si were surveyed, and the distribution status of 8 species of ecosystem-disrupting species for strengthening the health of aquatic ecosystems in local and small rivers was investigated. Based on the 5 watersheds in Seosan-si, 48 local rivers and 49 lake reservoirs were selected, and 46 research sites were selected, taking into account the results of the literature search and the topography and habitat characteristics. Ecosystem disturbance species of fish were identified at 31 points, and it was confirmed that the large mouth bass (Micropterus salmoides) mainly inhabited the water purification section in the middle and lower reaches of the reservoir. Ecosystem disturbance plants were confirmed at 122 points by adding major colonies, and spiny lettuce (Lactuca serriola) was distributed over the river bank, and ragweed (Ambrosia artemisiifolia) was distributed in the vicinity of the artificial ground of the main reservoir, and it was confirmed that the prickly pear (Sicyos angulatus) was distributed partially in the Great Lakes. The Woncheon Stream in the Ganwol Lake Basin and Daeho Basin, and the Jwase Stream and Haemi Stream in the Seokmun Lake Basin were proposed as intensive management areas. The results of this study can be used as basic data for the functional evaluation of the small wetlands and creation of ecological spaces for living areas such as biotope gardens.
