Evaluating the ecological risks of living modified organisms (LMOs) before their commercialrelease is essential for safeguarding biodiversity and ecosystem stability. LMOconfined field trials offer controlled environments that simulate natural conditions,enabling researchers to assess ecological impacts, particularly on non-target organismssuch as arthropods. This study investigated the distributional patterns of arthropodswithin the Ministry of Environment’s LMO confined field facility in Seocheon,South Korea, over a 2-year period (2020-2021), to establish baseline ecological dataprior to LMO environmental release experiments. Arthropods were collected acrosseight survey rounds using sticky traps, aspirators, and sweep nets, and identified usingnational taxonomic references. A total of 132 species (2,309 individuals) in 2020and 154 species (3,352 individuals) in 2021 were recorded, with an overall total of 263species across both years. Hemiptera was the most dominant order across both years,while Coleoptera and Diptera showed marked declines in 2021. In contrast, Araneae,Hymenoptera, Lepidoptera, Orthoptera, and Odonata increased substantially. Moreover,104 species not observed in the 2020 survey were newly identified during the2021 field survey. Dominant species also shifted between years, suggesting that localenvironmental factors and seasonal dynamics influence community composition. Thearthropod dataset established through this study can serve as an important ecologicalreference for future ecological risk assessments of LMOs and the monitoring ofnon-target organisms.

It has been noted that the main cause of biodiversity loss is influx of alien species. Specifically, habitats destruction, economic loss, and human injury are increasing due to invasive alien species. There were 2,167 alien species in Korea. 21 alien species of extraterrestrials including Lycorma delicatula, Solenopsis invicta, Myocastor coypus, and Spartina alterniflora at high risk through ecological risk assessment, are designated as invasive alien species. Alert species, which may have negative impact on ecosystems when they are introduced into the country, are assigned to 127 species through the ecosystem risk evaluation. To list such alien species to prevent invasion of alien species in advance, and to minimize damage caused by imported alien species, a national level management system called the Conservation and Use of Biological deversity Act was established, but there is a lack of a systematic management system in accordance with degree of risk. There is also a risk assessment chart should be developed thatreflects ecological characteristics of each taxon and evaluation criteria in predicting the risk.
