This study analyzed the population, sex ratio, and age of Korean long-tailed goral using camera trapping in the whole area of Woraksan National Park (WNP) in order to obtain data on the restoration, population increase and habitat expansion of endangered species “long-tailed goral” in the WNP. A total of 80 scouting cameras were installed at least one per a grid (1 km×1 km) in each of the 33 grid areas (2 km×2 km) selected from the five survey areas used in this study. A total of 91 individuals was identified from 2,866 cuts among 7,381 photos taken. There were 58 individuals in Yongbong, Joongbong and Habong. Among those we found 20 individuals in Yonghwa valley, 20 in Mansu valley, 5 in Poam, and 1 in other area, respectively. We recognized that there were 70 adults (76.6%), 15 sub-adults (16.5%) and 6 calves (6.6%), and 41 females (45.1%), males (31.9%) and sex unknown (23.1%). As a result of this study, it was confirmed that the number of 91 individuals of long-tailed goral are living in WNP, where 15 individuals have been initially released by the long-tailed goral restoration program at the beginning time in 2007. The largest number of this species was found in Yeongbong-Jungbong-Habong area where animals were released at beginning. As the population of Yongha-Mansu area increased, the population size was increased over whole area of WNP. Especially, we found that some of those released were migrated to the neighboring region, Soklisan National Park. In the future, it is necessary to take further studies such as measuring the maximum capacity, evaluating of the feasibility, and establishing the management of the increasing population, and we will provide data to promote the restoration and conservation policy of long-tailed goral in the WNP.
