We conducted field surveys of amphibians and reptiles over a two-year period in 16 lagoons along the eastern coastlineof South Korea, and determined the habitat characteristics correlated with the number of amphibian and reptilianspecies and individuals. We documented 11 amphibian species and 8 reptilian species. The dominant amphibian specieswas the black-spotted pond frog (Rana nigromaculata), and the dominant reptilian species was the red-eared turtle(Trachemys scripta elegans), an invasive species. Among the 14 habitat characteristics, connectivity to mountainous areasignificantly affected the number of amphibian and reptilian individuals. Other factors, including emerged plant cover,salinity, pH, the number of birds for amphibians and connectivity to agricultural land, lagoon perimeter length for reptilesalso influenced the number of species or individuals of them. Our results demonstrate that these lagoons are hometo more amphibians and reptiles than has been previously known. To effectively conserve herpetofauna in the lagoonecosystem, lagoons as well as surrounding wetlands, grasslands, and mountainous areas should be protected.
