The chemical composition of bark was analysed in material collected from young beech trees stripped and not stripped by deer. The analyses determined contents of cellulose, lignin, holocellulose, pentosanes, substances soluble in cold and hot water, extractives, substances soluble in 1% NaOH as well as ash content. Volatiles from bark of the trees were also identified. A lesser share of hemicelluloses was recorded in the bark of stripped trees. These trees were also characterised by lower intensity and amounts of volatiles.
