It has been 10 years since the first construction of wildlife crossing passage by the Republic of Korea's Ministry of Environment in 1998. The objective of this study was to suggest effective road-kill policy based on analysis of research reports and countermeasures. The research contents and methods of 26 reports published by government and public institutes were reviewed. The results were as follows. First, Korea has 379 wildlife crossing structures, the fourth most abundant number in the world, meaning the government's aggressive policy. Second, 17 reports introduced abroad case and 14 reports suggested fundamental guidelines, however, only 1 or 2 reports repeated field survey for wildlife movement around roads and crossing structure. Consequently, we inferred that Korea showed active efforts to construct countermeasures but passive to conduct fundamental field research. We suggest, therefore, road-kill policy of Korea should more invest for wide and deep field survey to understand wildlife moving habit and to monitor crossing structures.
