Ulmus laciniata is a strategic food resource for Cervus elaphus xanthopygus, especially in autumn and spring. 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, are presented. Two maxima in the content of water-soluble polysaccharides were revealed: during the shoot growth period (June) and during 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). The content of pectin substances, unlike water-soluble polysaccharides, changed slightly during the year. The groups of substances studied are classified as the most bioavailable polysaccharides with extensive physiological activity. In addition, the data obtained may explain the feeding behavior of C. elaphus xanthopygus, which lives in Primorskii krai.
