Abstract PDF: Evaluating the ecological risks of living modified organisms (LMOs) before their commercial release is essential for safeguarding biodiversity and ecosystem stability. LMO confined field trials offer controlled environments that simulate natural conditions, enabling researchers to assess ecological impacts, particularly on non-target organisms such as arthropods. This study investigated the distributional patterns of arthropods within the Ministry of Environment’s LMO confined field facility in Seocheon, South Korea, over a 2-year period (2020-2021), to establish baseline ecological data prior to LMO environmental release experiments. Arthropods were collected across eight survey rounds using sticky traps, aspirators, and sweep nets, and identified using national taxonomic references. A total of 132 species (2,309 individuals) in 2020 and 154 species (3,352 individuals) in 2021 were recorded, with an overall total of 263 species 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 the 2021 field survey. Dominant species also shifted between years, suggesting that local environmental factors and seasonal dynamics influence community composition. The arthropod dataset established through this study can serve as an important ecological reference for future ecological risk assessments of LMOs and the monitoring of non-target organisms.

Abstract PDF: The National Institute of Ecology in Seocheon, Chungcheongnam-do, exhibits and studies Korea’s diverse ecosystems to communicate the importance of biodiversity conservation to the general public. The site faces the challenge of preserving the natural environment while ensuring visitor convenience. This requires systematic data collection to quickly detect and respond to threats from pests and natural disasters. In this study, high-resolution orthoimages were acquired to monitor ecological changes using unmanned aerial vehicles. Images were captured through flights monthly from March to July 2024. Digital elevation models and orthoimages were generated to identify dead trees and assess areas of damage caused by heavy rainfall. The study covered an area of 998,655 m2, and the image resolution was 3.6 cm/pixel. The orthophotos were useful in identifying plant pest damage. They also helped evaluate damage caused by rain, showing that the total area of damage was 29,384 m2, mainly due to soil erosion. Furthermore, it is expected that the accumulation of such unmanned remote sensing image data can also be applied to the safety management of various natural conservation areas and public facilities.

Abstract PDF

In this study, climate variables and distribution patterns of native organisms were investigated in an enclosed field within the institute of living modified organism (LMO) risk assessment designated by the Ministry of Environment (MOE) of South Korea. The data includes changes in temperature, precipitation, humidity, sunlight, wind direction, and velocity within the LMO confined field from 2019 to 2023 as well as information on plant diversity and soil microbial communities. This data can be used as the basic data when establishing LMO safety management policies by the MOE such as preparing guidelines for systematic LMO risk assessment reflecting domestic environmental characteristics and risk assessment of LMOs for environmental remediation and natural ecosystem. In addition, this data can be usefully used as the comparative data for LMO risk assessment by other ministries such as the Ministry of Agriculture, Food and Rural Affairs, the Ministry of Trade, Industry and Energy, and the Ministry of Oceans and Fisheries.
