4-4.5 m. Its mean increment is 0.1-0.15 m. This value results notonly from lower height growth of Manna ash but also from frequentdamage by forest game. If browsing of terminal buds damages trunksof trees they grow to several lateral sprouts.It is similar for diameter growth (Fig. 4). Austrian pine reachesthe greatest diameters. In the locality Hrhov at the age of 30-35 yearsaverage diameter is 14-12 cm and in Periská locality 8-14 cm at theage of 20-37 years. Mean diameter increments are about 0.35-0.45cm. Manna ash has average diameter only 1.5-2.0 cm in Periskálocality and 4.0-4.5 cm in Hrhov. Mean increment of ash is only0.06-0.14 cm. Of other tree species height growth of oak andMahaleb cherry within the range 1.0-5.0 m is interesting similarly tothe heights of beech trees of about 4.0-5.0 m in the locality Periská.Other tree species, first of all shrubs, reach heights only within 0.5m.In addition to comparing average heights and diameters alsotheir variability was assessed. The result was a finding that Austrianpine reacts to the differences in the quality of site the least of all treespecies.Fig. 3 Mean height of the tree species on experimental plots oflocality Hrhov (H) and Periská (P)~ 364 ~
