Linear infrastructure such as roads, railways, and irrigation canals causes habitatfragmentation and disrupts wildlife movement, negatively impacting ecosystems. This study investigated the physical characteristics of 80 artificial structures acrossSouth Korea and analyzed the status of wildlife entrapment prevention facilitiesand mammal entrapment incidents within irrigation canals. The surveyed structures,including irrigation canals, drainage canals, and roadside ditches, had an averagelength of 2.57 km, width of 3.34 m, and height of 1.4 m. Most structures (88.8%)were concrete, while 11.3% were mixed concrete and earthen canals. Wildlifeentrapment prevention facilities, including escape facilities, cross-movementstructures, and avoidance guidance facilities, were installed at low rates. Mammalsentrapment incidents were observed 620 cases, with Korean water deer (Hydropotesinermis) and common raccoon dog (Nyctereutes procyonoides) being the mostfrequently observed. Additionally, entrapment incidents involving the endangeredEurasian otter (Lutra lutra) and leopard cat (Prionailurus bengalensis) were alsorecorded. Escape facilities and guidance facilities showed no significant differencein the average occurrence rates of mammals, but the maximum occurrence rateswere lower in sections where these facilities were installed. This study providesessential baseline data for policy development and management strategies aimedat mitigating wildlife entrapments and improving ecological connectivity in artificiallinear infrastructure.
