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

Przewalski's horse had reached the brink of extinction but was reintroduced successfully back into the wild. The tarpan became extinct in the 19th century, though it is a possible ancestor of the domestic horse; it roamed the steppes of Eurasia at the time of domestication. However, other subspecies of "Equus ferus" may have existed and could
