As global economic growth has influenced the increase in international interactions through activities such as travel and trade, there has been an escalation in the export and import of species valuable to the agriculture and fishing industries, pets, and ornamental alien species. Until 2018, a total of 2,160 alien species, including 1,826 animal species and 334 plant species, were imported into South Korea, which is an increase by approximately 95% compared to 2011; thus, the import of alien species into South Korea is increasing. The appearance of species with the potential for ecosystem disturbance has been increasing, following incidents such as an outbreak of alien invasive species caused by changes in the environment, including climate change. The invasive alien species adapted to Korea are exacerbating disturbances on the ecosystem through their rapid proliferation and thriving feeding ability.
