The movement distance and home range size of Pelophylax chosenicus were identified in the rice paddy and ecological park as alternative habitats from July to November 2017. A total of 39 frogs were tracked by radio tracking method. As a result, the average move distance in the population of rice paddy was 11.7 ± 1.9 m (n = 64) and the population of ecological park was 24.7 ± 4.3 m (n = 39). The move distance between the two populations was significantly different. The mean MCP of the population of rice paddy was 181.2 ± 110.8 m² (n = 11) and the population of ecological park was 416.1 ± 276.2 m² (n = 10), but there was no significant difference. The population area of rice paddy was 4,160 m² (Kernel density 95%) and the core area was 1,080 m² (Kernel density 50%). The population area (Kernel density 95%) of ecological park was 5,391 m² and the core area (Kernel density 50%) was 736 m². This study shows that it is appropriate to construct the area of alternative habitat for P. chosenicus at least 1.33 ha, and it is more advantageous for the ecological park to be constructed than the paddy field with high development pressure and human interference. If the rice paddies were to be abandoned for several years, or to be used traditional farming methods, such as refraining from using agricultural machinery and chemicals, they could be used as alternative habitat for P. chosenicus.
