ニホンジカ
Sika deer have been introduced into a number of other countries, including Estonia, Latvia, Lithuania, Austria, Belgium, Denmark, France, Germany, Ireland, Netherlands, Norway, Switzerland, Russia, Romania, New Zealand, Australia, the Philippines (Jolo Island), Poland, Sweden, Finland, Canada, the United Kingdom, and the United States (Maryland, Oklahoma, Nebraska, Pennsylvania, Wisconsin, Virginia, Indiana, Michigan, Minnesota, Maine, Wyoming, Washington, and Kansas). In many cases, they were originally introduced as ornamental animals in parklands, but have established themselves in the wild. On Spieden Island in the San Juan Islands of Washington, they were introduced as a game animal.
