Abstract: This study was conducted to clarify the habitat use of the Eurasian otter Lutra lutra in the Hangang River Water System, South Korea. Researchers evaluated a total 358 habitat points of this species during April 2009 and October 2010. Altitude, river width, river depth, water velocity, bottom status, bankside vegetation, vegetation cover and pollutants were significantly different among Bukhangang, Namhangang and control areas. Correlation analysis revealed that several habitat variables were correlated with each other. Habitat type, spraints and available habitat, classification of rural and urban areas, surrounding conditions for hiding, direct human disturbance and degree of pollution were the most important factors determining the habitat use of the Eurasian otter in the Hangang River Water System. Long-term ecological studies of the ecology and habitat use patterns of the Eurasian otter are essential to conserve this species and its habitat.
