Abstract: Two methods were used to estimate the foodstoringterritory of communal overwinter nest of Brandt's vole, that is, the rootcounting method and runwaymeasuring technique. It reveals that the 2 estimators accord with direct proportion relationship. The utility rate of the group on its food storing territory is about 67 percent. The runway measuring method may be considered as a convenient estimator of the food storing territory of communal over winter group of this species
