Young tree species were injured selectively as bark of deciduous trees were more attractive for voles than coniferous. Differences were found also in various tree categories as to age. To explain rodent selectivity in bark damage to young trees, bark of spruce, beech and rowan was chemically analysed. These selected trees were all important in mountain forestry regeneration. The bark of younger stems of rowan and beech (C1) contained more nutritive substances (fat, crude protein) and the low content of fibre. The good nutritional quality and the lowest content of fibre were found in the bark of younger (C1) stems of rowan. The bark of older beech stems (C2) showed the highest fibre and ash content. Differences between the broadleaved tree bark and spruce bark were significant as to crude protein and the fibre content. Chemical analysis explained selectivity between broad-leaved and coniferous trees.
