This species has a large population size and a wide distribution. No decline in population size has been detected, and there are no known widespread major threats.
|Previously published Red List assessments:||
|Range Description:||Distributed in mountain forest-steppes and steppes from Southern Siberia and Altai (Russia) to Manchuria. Two isolated population in north, in Yakutia (S. u. jacuensis) and east of the range, between Amur and Burei Rivers in Russia and N Heilongjiang in China (S. u. menzbieri). In China distributed in Altai and Sayan mountains; Xinjiang, Altai mountains; Xinjiang, Tian Shan mountains. In Mongolia found in Mongol Altai, Hangai, Hövsgöl and Hentii mountain ranges, as far south as Aj Bogd Massif in Trans Altai Govi Desert. Recently recorded in the northern portions of Ikh Nartiin Chuluu Nature Reserve in Eastern Govi.|

|Population:||It is common and sometimes abundant species. Population size very much differs depending on the habitat. For example, in Transbaikalia in steppe river valleys population density is up to 250 burrows per ha (Badmaev, 1996). In Tuva it is about 100 burrows per ha (Ol'kova, 1962). In other habitats density is much lower, in wormwood and cereal steppe it is about 5 animals per ha, and in subalpine zone it is 1-2 animals per ha (Shilova and Savinetskaya, Biodiversity Conservation Centre web-site
|Current Population Trend:||Stable|
|Habitat and Ecology:||Inhabits semi-desert and mountain steppe habitats along the edge of forests. In China found in thinly wooded savannas and grassy steppes bordering the Gobi desert. In addition to grasslands, they occupy bushy terrain among oaks and white or black beech groves, alpine meadows, and wet areas along river valleys. Lives in colonies with a labyrinth of burrows. Burrows are characteristically 8-13 cm in diameter and surrounded by a large mound of soil (up to 2 m in diameter and 40 cm high) Diurnally active; although most active at dawn and dusk. Diet consists of green vegetation and seeds, but also insects. Before hibernating makes a store of vegetation to utilize following arousal. Hibernates from October until late March/mid April. Reproduce once per year in spring; litters of 3-9 young are produced following a 30 day gestation. Start mating on second year.|
|Major Threat(s):||Hunting for international trade in skins once occurred at high levels, between 1958 and 1960 it was estimated that as many as 418,400-551,000 individuals were killed annually (Stubbe, 1965). This activity is now believed to have ceased and no other threats are known to be impacting upon this species at present.|
|Conservation Actions:||Occurs in some protected areas (approximately 11% of the species’ range in Mongolia).|
