Siberian roe deer
Seven existing species of mammals were already acclimatized on land: the American mink, muskrat, raccoon dog, wild boar, Siberian roe deer, red deer and Sika deer. In parallel, work has been carried out to reintroduce the Forest-steppe marmot, the Eurasian beaver and the Russian desman (a species of mole that resembles a muskrat).
