The work contains the results of the inventory of damage in the first age class beech stands on the area of the Leśny Dwór Forest District (northern Poland). The inventory covered 515 487 trees aged 7–20 years, divided to 5 435 200 m 2 big sample plots representing 1,504.15 hectares of beech stands. Deer damaged 33% of the beech trees. The number of damaged trees is correlated with their availability for deer (share of tree species in stand and number of trees). Most of the stands (67%) were damaged to the extent of 20%. Significant difference in damages between subdistricts was found.
