Based on the Invasive Alien Species Act and the Basic Policy, the list of designated Invasive Alien Species (IAS), Uncategorized Alien Species (UAS) and Living Organisms Required to have a Certificate Attached during their importation in order to verify their types (LORCA) was proposed by academic experts on properties of living organisms. Candidates for designated IAS were selected from among alien species whose adverse effects or the possibilities are already reported by academic articles in the world.
