The species inhabits temperate mixed forests with warm summers and many oak, birch, and maple trees, as well as flooded meadows where water frequently covers the ground and there is abundant grass; it also lives in taiga forests characterized by cold winters and numerous coniferous trees such as spruce and pine, and tundra regions with very cold temperatures and short summers, where trees are almost absent and there is much moss. Ferrets occupy terrestrial landscapes including forest floors and woodlands. The climate varies, encompassing cool summers of +15 to +20 degrees Celsius, consistently wet conditions with frequent rain and high humidity, warm summers with abundant rainfall, warm winters that are not very cold, and pleasant summers of +20 to +25 degrees Celsius.
