ABSTRACT

This study was conducted to examine the impact of the correlation between habitat suitability of the Saemangeum lake area for otters and spatial variables (watersides, wetlands, farmlands, urban areas, roads, etc.) on the inhabitation of otters. As a result of the habitat suitability analysis, it was found that 380grids of 1097 grids (34.6%) studied are most suitable and suitable, whereas 413 grids of 1097 grids (37.7%) of the total are marginal and unsuitable. Comparatively analyzing otter traces data against for each spatial variable in the Saemangeum area revealed that the distance to the road or man-made areas is directly proportional to the number of otter traces, while more traces of otters were found areas close to waters. Despite the impact from the internal construction of Saemangeum lake, there found 2 to 6 times more otter traces in the area farthest from the urban areas and roads compared to the area nearest to the urban areas and roads. Thus, when restoring habitats for otters, a minimum of 500(m) distance to roads or urban areas, which can be considered as a threat to the habitats, must be secured.
