ABSTRACT

The purpose of this study was to ascertain the ecological state and problems of eco- bridgeson Korean roads. The study was conducted from March to April 2007 by checking ecologicalfactors and wildlife around the eco-bridges and habitats. 8 representative eco-bridges wereselected by their bridge shape and condition of location. After field survey, we analyzed idealtrails for wildlife using field data, digital topology maps, satellite images, and land use map. Inaddition to trail analysis, we identified the propriety of the eco-bridges through PopulationViability Analysis. Because of unsuitable location and management, we found that most of thebridges are not proper for wildlife dispersal. Moreover, in some habitats, we could expect thatsome local populations might be extinct without appropriate treatments.
