Irresponsible release and escape of pet raccoons (Procyon lotor) has caused their naturalization in Hokkaido, Japan. Raccoons had naturalized in cattle breeding area at first, where they could find food easily, then spread throughout Hokkaido.
Raccoons have opportunistic and omnivorous feeding habits, taking crops and fruit in agricultural areas and predating indigenous species such as the Japanese crayfish (Cambaroides japonicus) and the Ezo salamander (Hynobius retardatus) in forests.
Nuisance control harvests of invasive alien raccoons were conducted in some areas in Hokkaido, but raccoons show high reproductive power and potentially rapid rate of population growth, thus it will be impossible to control invasive raccoons only by nuisance control harvesting. Intensive extermination under scientific control programs on the basis of adaptive management is indispensable to controlling invasive alien raccoons. As public awareness of invasive alien raccoon issues is low, except in some areas where agricultural damage is serious, educational efforts will be needed regarding invasive alien raccoon issues, especially irreversible impacts on native ecosystems. http://www.hokudai.ac.jp/huisd/en/ab.html
