AB  - In the LHC Obrova noha management-plan area (Municipal Forests Prostějov), peeling and browsing damage to spruce (Picea abies) caused by red deer was monitored. In total, 20 plots of an area of 25 × 25 m were monitored in stands aged 26-65 years. On the whole, 56% of 1561 trees were damaged by peeling and browsing, 82% of the damaged trees were attacked by Stereum sanguinolentum (Alb. et Schw.: Fr.) Fr. Trees in the 3<sup>rd</sup> age class affected by rot show the highest proportion, viz 92% trees damaged by peeling. In the plots, in total 90 sample trees with the presence of rot were cut down. Peeling damage happened 6 to 41 years ago. The rot affected 10 to 94% of the sample tree stem volume (on average 39%). The volume of devalued wood is in positive correlation with a time elapsed after peeling damage (r = 0.683). The rot spread vertically through the tree stem by an average speed of 10.5 cm.year<sup>-1</sup> (from 1.3 to 28.1 cm.year<sup>-1</sup>). The progress rate negatively correlated with a period elapsed after the stem damage (r = -0.723).
