Steppe Lemming - Ecology

Ecology

The steppe lemming is a colonial species digging lengthy burrows. It has a partially underground mode of life, being active during the day, but only going above the surface for short periods. It feeds on various parts of plants, including seeds. It reaches sexual maturity at the age of six weeks and can produce up to six broods in a year, with five or six young in each. Under favourable conditions, reproduction continues throughout the year. The numbers of steppe lemmings vary greatly according to climatic conditions and the availability of food. Migrations are observed during years of mass outbreaks.
