| Popis: | Damage caused by bark peeling and browsing by red deer to Picea abies was investigated in two localities in the Českomoravská vrchovina Highlands. 127 experimental plots of 50 × 50 m in size were monitored in stands aged from 15 to 93 years. In total, 44% of 16,700 inspected trees were damaged by bark peeling and browsing. The area of gaping wounds varied from 50 to 1,650 cm2. Stem decay affected 68% of the damaged trees. Some properties of the decay were analysed from 200 sample trees felled on the plots. Bark peeling damage occurred when the trees were 4 to 48 years old. Decayed wood accounted for 22-70% (mean 42%) of the merchantable stem volume of sample trees. The mean rate of the vertical decay spread was 17.4 cm per year (ranging from 4-63 cm per year). Mean decay volume correlated positively and mean spreading rate correlated negatively with the time elapsed from the bark peeling damage occurrence. |
