|Scientific Name:||Mustela sibirica|
|Species Authority:||Pallas, 1773|
|Taxonomic Notes:||Abramov (2000), Kurose et al. (2000), and Graphodatsky et al. (1976) supported separation of itatsi from sibirica. It is sometimes considered a subspecies of the Siberian Weasel Mustela sibirica; hence Japan is left out of the distribution range. Mustela lutreolina of Java and Sumatra is also sometimes considered part of M. sibirica (e.g., Corbet 1978), but is here considered distinct. See also note in documentation about the introduced populations.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor/s:||Duckworth, J.W. & Abramov, A.|
|Reviewer/s:||Belant, J. (Small Carnivore Red List Authority) & Schipper, J. (Global Mammal Assessment Team)|
This species is listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
|Range Description:||This species is found in northern Myanmar, Lao PDR, China, Japan, DPR Korea, Republic of Korea, Pakistan, Nepal, India (Himalayas), Bhutan, Russia (from Kirov Province, Tataria and western Ural Mountains throughout Siberia to Far East), Taiwan, and northern Thailand (Pocock 1941, Duckworth 1997, Wozencraft, 2005). In Japan, it has been introduced to Honshu, Shikoku, and Kyushu Islands (Abe, 2005). It is native on the islands of Sakhalin, Kamishima, and Jeju (Abe, 2005). The distribution in southeast Asia is poorly known (A. Abramov pers. comm. 2006). The species was recorded recently in two locations in national parks in Thailand (Kanchanasaka pers. comm) and in one location in Lao PDR, Nakai-Nam Theun National Biodiversity Conservation Area in 1996 (Duckworth, 1997; sight record only). Gao and Sun (2005) conducted a study of the effects of this species on Liadong oak (Quercus wutaishanica) in Beijing Forest Ecosystem Research Station (BFERS, 40 00 N, 115 26 E), one of the research stations affiliated to the Chinese Ecosystem Research Network (CERN) of the Chinese Academy of Sciences (CAS). This species seems to prefer mountains from 1500 to 5000 m in the southern part of its range (Lekagul and McNeely, 1988) but there is one provisional sighting in Khammouan Limestone National Biodiversity Conservation Area in valley semi-evergreen forest amid karst at about 500 m in 1998 (Robinson and Webber, 1998).|

|Population:||The species is widespread and abundant in Siberia and China (Abramov pers. comm). It is also common in northern central Korea as well, where few other mammals other than rats and squirrels are currently easily seen (W. Duckworth in litt. 2006).|
|Habitat and Ecology:||This species is found in "a wide variety of habitats, including dense forest, dry areas, and human villages and towns, where it dens in any convenient shelter, including burrows of other animals (Lekagul and McNeely, 1988)." It occurs in primary and secondary deciduous, coniferous and mixed forests, as well as open areas with small patches of forest enclaves and forest steppe. It is also found along river valleys. It is found from to over 3000 m in Nepal. In Bhutan, it is found as low as 1500 m and up to 4800 m (Thinley, 2004). In China, its altitude can reach up to 5000 m. It feeds on small mammals, such as voles, squirrels, mice and pikas, amphibians, fish, and carrion. During the summer time, it feeds on pine nuts. In Lao PDR this little known species has been observed in primary evergreen forest at 1000 m (Duckworth 1997a), and possibly in valley semi-evergreen forest amid karst at about 500 m (Robinson and Webber 1998a; M. F. Robinson, 1998). It occurs commonly down to sea-level in the north of its range, e.g. Korea (J. W. Duckworth pers. comm.).|
|Major Threat(s):||There are no major threats known to this species. It is legally hunted in Russia for its fur (A. Abramov pers. comm. 2006)."Unfortunately, the small forest carnivores are not well protected by either the local forest managers or the residents living in the forest areas in China, though most of them are listed as protected animals by the national or local governments. Weasels and badgers are largely hunted for their hides and meat. (Gao and Sun, 2005)". Unsustainable hunting for skins, for international trade. However, hunting levels are low at present, reflecting the low commercial value of skins. Competition for resources with sable (Martes zibellina) and natural wildfires also constitute minor threats.|
|Conservation Actions:||In Lao PDR, this species was observed in Nakai-Nam Theun National Biodiversity Conservation Area in 1996 (Duckworth 1997a), and provisionally sighted in Khammouan Limestone National Biodiversity Conservation Area in 1998 (Robinson and Webber, 1998a; M. F. Robinson, 1998). Gao and Sun (2005) conducted a study of the effects of this species on Liadong oak (Quercus wutaishanica) in Beijing Forest Ecosystem Research Station (BFERS, 40 00 N, 115 26 E), one of the research stations affiliated to the Chinese Ecosystem Research Network (CERN) of the Chinese Academy of Sciences (CAS). This species is listed on CITES Appendix III (India) and is on the Tibet wildlife protection list (Li et al. 2000). It is on the China Red List as Near Threatened, and it nearly met the criteria for Vulnerable A2cd. There is a conservation need to establish a sustainable harvest level through population monitoring.|
