Estimating the Level of Trees Damages and Financial Losses by Logging

Abstract

The presented results paper can be divided into two groups - the number of injuries according to the affected tree sections (root, buttress, trunk), and according to size intervals (in cm2). A survey of injuries after harvester’s work was carried out for the age classes 3 (41-60 ys), 4 (61-80 ys) and 5 (81- 100 ys). In age class 3-1.50% of the trees left in the stand were damaged, i.e. 19.3 trees/ha. In age class 4, the percentage of injured trees increased by 0.83% up to 2.38% (23.7 trees/ha) and in age class 5 to 2.25% (13.0 trees/ha). Without taking the age classes into consideration, the root buttresses were damaged to the highest degree (18.9 injuries/ha). The damage of the root system amounted to 9.0 injuries/ha.
