The paper analyzes data on browsing damage to food-attractive woody species, viz. Acer campestre, Acer pseudoplatanus, Acer platanoides, Fraxinus excelsior, Sorbus aucuparia and most often eudominant Fagus sylvatica. The field survey was carried out in 2005-2007. Analyzed data come from 34 transects at 15 localities in the CR with different abundance of ungulates (Capreolus capreolus, in some areas also Cervus elaphus or Dama dama). Trees occurring in natural regeneration under a stand were monitored up to a height of 150 cm and the presence of new browsing damage was monitored. Differences between the percent of damaged individual plants of one species and the percent of damaged individuals of all woody species in the transect as well as the proportion of these variables significantly correlated with the dominance of the given species. The higher the proportion of Fagus sylvatica in the stand, the higher the relative intensity of browsing damage.
