Ulmus laciniata is a strategic food resource for Cervus elaphus xanthopygus, especially in autumn and spring. The article presents the results of a study of the seasonal content of water-soluble polysaccharides, their monosaccharide composition, extracted from the bark and bast of U. laciniata. Two maxima in content of water-soluble polysaccharides were revealed: during the shoot growth period (June) and a slightly lower one during the preparation for winter dormancy (October). The minimum content is observed during the beginning of the growing season (April-May). Content of pectin substances, unlike water-soluble polysaccharides, changed slightly during the year. The studied groups of substances are classified as the most bioavailable polysaccharides with extensive physiological activity. In addition, the data obtained may explain the feeding behavior of the C. elaphus xanthopygus, which lives in the Primorsky Territory.
