Modelling Stand Damages and Comparison of Two Harvesting Methods

Sažetak
This paper deals with the problem of tree damage in a remaining stand. Two models were
used for assessment of stand damage over the entire production period. Damage accumulates
on the trees and in the stand, which is why the total share of damage tends towards the
limit 100% if the number of thinnings increases. Parameters used in the models were established
partly by previous field measurements and partly by simulations measurements. Motor-
manual and cut-to-length technologies were analysed and compared according to the total
number of damaged trees and the structure of trees according to the number of injuries. It
was found that motor-manual technology causes more damage to trees and results in worse
tree structure, meaning more than one injury. Many unanswered questions provide plenty
of opportunities for further research.
