Domestic Reutilization Status of Invasive Turtle Species in South Korea Based on Trachemys scripta

Abstract

This study was conducted to determine the reutilization, distribution, and import status of invasive alien turtles in South Korea. The results showed that a total of nine invasive alien turtle species including Trachemys scripta, which is designated as an ecosystem disturbing species (EDS), were traded in the traditional market, and 84 of 169 turtles registered through the National Animal Welfare Information System were reintroduced to new breeders. Additionally, the distribution of invasive alien turtles was confirmed at 341 points in 109 cities, and we found that, on average, 7 tons of non-indigenous turtles are imported annually from over 20 countries to South Korea. These results indicate the urgent need for efficient management of invasive turtles in South Korea. Therefore, we suggest (1) activating a purchase program of EDS through local governments, (2) establishing links with research institutions and experts to improve the initial species identification accuracy of the National Animal Welfare Information System, (3) establishing a follow-up management system after the designation of EDS, and (4) providing a free collection service for exotic turtles abandoned by breeders. Finally, this study provided the current distribution of invasive alien turtles in South Korea and the exotic turtle import status over 21 years.
