A Study on the Occurrence of Racoon Dog (Nyctereutes procyonoides) Roadkill Using the Korea Roadkill Observation System: Euigeun Song, Kihyun Kim, Sehee Kim, Hanbi Lee, Jiyoun Kim; GEO DATA. 2024;6(4):430-434. Published online December 31, 2024; DOI: https://doi.org/10.22761/GD.2024.0061

Abstract PDF: Since industrialization, the pressure for development has increasingly intensified conflicts between wildlife and humans. Concerns have grown regarding the transmission of diseases by wildlife as carriers of zoonotic diseases, human casualties and economic losses due to roadkill incidents, and the decline in biodiversity. This study aims to provide fundamental data for resolving conflicts between raccoons and humans by analyzing the annual and monthly trends of raccoon roadkill incidents approved in the Korea Roadkill Observation System from 2019 to 2023. Over five years, 11,328 raccoon roadkill cases were approved, showing a rising trend in raccoon roadkill incidents each year. Monthly data revealed that October had the highest number of incidents, with 2,316 cases, and roadkill occurrences were found to be significantly higher during autumn and early winter. These findings are expected to serve as fundamental data for addressing future conflicts between raccoons and humans.

Investigation of Wildlife Crossing Structures in South Korea: Euigeun Song, Sooahn Heo, Il Ryong Kim, Sehee Kim, Hanbi Lee; GEO DATA. 2023;5(4):273-276. Published online December 22, 2023; DOI: https://doi.org/10.22761/GD.2023.0041

Abstract PDF: Roads, railways and infrastructure are constructed with consideration of their environmental impacts, especially habitat fragmentation. Wildlife crossing structures increase the permeability of roads and other linear infrastructures for wildlife by allowing animals to safely cross under or over roads and by reducing the risk of wildlife-vehicle collosions. We investigated the location and type of 564 wildlife crossing structures in South Korea. Between April and October 2023, we identified 365 overpasses and 199 underpasses of wildlife crossing structures respectively. Gyeonggi-do and Gyeongsangbuk-do had the largest number of wildlife crossing structures. This study can provide basic information for the effective management of wildlife crossing structures.
