| The increase of human activities has been extensively changed the breeding habitats of birds directly or indirectly, where the reproductive success of the birds has been seriously reduced. Leisure activities on water, such as fishing, influenced the breeding biology of waterfowls. However, few researches have been done for this in Korea. We examined the effects of fishing activity on nest selection and density of four waterfowl species at Namyang Lake: Coot (Fulica atra), Moorhen (Gallinula chloropus), Little Grebe (Podiceps ruficollis), and Great Crested Grebe (Podiceps cristatus). We divided the Namyang Lake into three study areas. Except for the number of anglers, there were no significant differences among the three study areas in the kinds of avian predators, the water depth around study areas measured for possible territorial predatory mammals' passing over, and the values of Relative Importance Percentage of occupying plants. The results showed that waterfowls bred in Namyang Lake preferred the areas with few anglers for the nests. From this study, we recommend that leisure activities including fishing should be prohibited or restricted during the breeding periods of waterfowls for the stable breeding success and that further systematic researches and managements for the species are necessary. |
