Abstract
Despite the technical diversity of techniques for winter feeding of wild ungulates, technologies for opening up forage fields during abnormal periods of the wintering cycle have serious biological potential. In winter, when high snow cover blocks access of ungulates to natural forage in form of fallen leaves and grass rags under snow, clearing biotechnical fields before vegetation becomes exposed is an efficient method of feeding the wintering fauna, especially for Siberian roe deer. By clearing snow from “winter pastures”, where biotech crops and grasses such as sunflowers, oats, peas, and alfalfa were sown, large roe deer groups can be provided with a good and balanced forage ration. Taken together, these biotechnical measures compensate for the lowering of the level of forage resources during winter anomalies and encourage the dynamics of roe deer population growth and the process of reproduction in this species.
