Population [top]

Population:It is common, partly rare, partly abundant. It is most abundant (25 individuals per ha) during young dispersal period, at altitude 2,600-2,800 m. In 1983, in Gissar State Reserve (Uzbekistan at altitude 2,000-2,300 m) population density was 2,8 individuals per ha (Volzheninov et al. 1986).
Current Population Trend:Unknown

Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits mountain and partly piedmont steppes, from deserted wormwood and sheep fescue on loess ad rubbly soil to high altitude cereal and mixed grasses steppes and meadow-steppes with some alpine vegetation. It is found in juniper stang and in openings at lower border of coniferous forest. Avoid wet meadows and agricultural fields.

In summer, day break in activity is very well pronounced. During hot days, as well as at night burrow exits are sealed with soil plug. Life cycle timing depends on the altitude and slope aspect. For example, hibernation ends from end of February (Issyk-Kul basin) to first decade of May (Chatkal highland). Young emerge from mid-May (lowlands) to second decade of June (Kuraminsky range). On overcast and windy days activity is reduced.

Burrows are simple, the majority of them are with one passage and one nesting cell. Wintering nest is at 1 - 1,5 m below ground, summer nests not lower than 1 m. They sometimes use burrows of voles and marmots. They feed mainly on underground plant parts, in spring consume green parts and flowers. To reach pea tree flowers the species climbs the trees. In some areas (Chatkal range) insects were up to 90% of stomach contents. It does not make caches. Reproduction is prolonged, beginning very much depends on spring weather. Average litters size depends on altitude, from 6 at 750-800 m, to 3-4 at above 2,000 m.
Generation Length (years):2-3
