Mouflon sheep. Mouflon have been introduced as game animals into Spieden Island in Washington state, and into the Hawaiian islands of Lanai and Hawaii where they have become a problematic invasive species. A small population escaped from an animal enclosure owned by Thomas Watson, Jr. on the island of North Haven, Maine in the 1990s and still survives there. Their normal habitats are steep mountainous woods near tree lines. In winter, they migrate to lower altitudes. The scientific classification of the mouflon is disputed. Five subspecies of mouflon are distinguished by MSW3: The eastern and the European mouflon often appear in
Mouflon domesticated animals, where they have naturalized in the mountainous interiors of these islands over the past few thousand years, giving rise to the subspecies known as European mouflon ("O. orientalis musimon"). On the island of Cyprus, the mouflon or "agrino" became a different and endemic subspecies known as the Cyprus mouflon ("O. o. ophion"). The Cyprus mouflon population contains only about 3,000 animals. They are now rare on the islands, but are classified as feral animals by the IUCN. They were later successfully introduced into continental Europe, including Portugal, Spain, France, Germany, central Italy, Switzerland, Austria, the Netherlands, Belgium, the
