Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Common to wet environments, especially lakeshores, riverbanks and streams surrounded by heavy vegetation. Although favoring waterside habitats they may invade adjacent agricultural areas and undeveloped lands when over crowded or forced out by rising water levels in spring and early summer. Reproduction occurs from April-November with up to six litters of five offspring per litter in favorable years. Gestation lasts about 20 days, and the interval between litters is 40-45 days. Females reach sexual maturity by 3.5-4 months, with males maturing a little later.
Systems: Terrestrial

Threats [top]

Major Threat(s): Possibly threatened by habitat loss through human-caused and natural wildfires. Drying of water sources and droughts also threaten this species, although it remains unclear if these represent natural environmental changes or are driven by anthropogenic activity.

Conservation Actions [top]

Conservation Actions: Approximately 14% of the species’ range in Mongolia occurs within protected areas. Common species in China and Russia; listed nationally as Least Concern.
