The main aim of the contribution was to introduce the preliminary results of the growth and vitality assessment of autochthonous Norway spruce (P. abies) and introduced Oriental spruce (P. orientalis), based on data available from inventories of plots in the collections of the Forest Arboretum Kysihýbel. Inventories of plots have been caried out at regular 10-years intervals and are available since 1984. Oriental spruce achieved lower values of individual as well as stand characteristics compared to Norway spruce in almost all inventoried plots. In the oldest plot with an age of 114 years, for Oriental spruce the mean diameter at breast height was 43 cm, mean height was 30 m, basal area was 60 m2.ha−1 and stand volume 754 m3.ha−1, for Norway spruce the mean diameter at breast height was 47 cm, mean height was 33 m, basal area was 66 m2.ha−1 and stand volume was 868 m3. However, the presence of rots as well as individual to patchy occurrences of dieback related to bark beetle infestation observed exclusively in plots of Norway spruce suggest on the lower susceptibility of Oriental spruce to damage related to biotic pests.
