Bark chemical analysis explains selective bark damage by rodents

Popis výsledku v původním jazyce

In National Nature Reserve Kněhyně-Čertův mlýn in Beskydy Mountains young trees are affected by bark damage caused by a rodent species. 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 category) 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 clearly
