| Invasion information | ||
| Range in Japan | Southern Hokkaido and Sadogashima Is. |
|
| Origin | Tohoku District to Hokkaido. Unknown for Sadogashima population (somewhere in Honshu). | |
| Date | In Hokkaido, this species was bred for fur production since just before W.W.II., and after released. In Sadogashima, released in 1959 to 1963. | |
| Route | Deliberate: Introduced to Hokkaido for fur production, and to Sadogashima for control of the Japanese hare Lepus branchyurus as a forestry pest. | |
| Impact | Potentially: Competition and Hybridization with sable on Hokkaido. Actually: Predatoin on native hare. Native organism(s) affected: Sable Mertes zibellina in Hokkaido, potentially competitive and/or hybridizing with M. melampus. Japanese hare Lepus branchyurus in Sadogashima (sometimes treated as an endemic subspecies L. b. lyoni), declined by predation by M. melampus. As a result, the hare on Sadogashima has been listed in the Red Data Book of Niigata Pref. | |
| Regulation in Japan | No action for prevention, mitigation, control, or eradication. | |
| Introduced range in other countries | None. | |
