【 摘 要 】

From 2003 to 2005, this work studied the preference of tree species on non-forest land in the forest district Soutok (Southern Moravia, Czech Republic) in order to evaluate the suitability of the area for the development and the its importance in relation to the decrease of damage in neighbouring production forests. The diet included the total of 14 tree species with diameter interval reaching from 1–10 cm to 191–200 cm. The most preferred species was Common Ash (Fraxinus excelsior) (40.5 %) with the diameter 1–10 cm and willow (Salix spp.) (31.7 %) with the diameter 11–20 cm – both species with good ability to regenerate. Activities of European beaver negatively influenced the population of European white elm (Ulmus laevis), which belongs to the endangered species. Significant is the low ratio of poplars Populus spp. (7.9 %) caused by the forest management. Maintaining the suitable tree composition and a sufficiently high percentage of individual tree species – in favour of willows and poplars – can result in the needed decrease of stress caused by the population of beaver on the adjacent forest stands and in the decrease of possible damage.
