"One of the main aims of forest management is to take care about sustainable stability and good health of forest ecosystems, which should fulfill their production and other important functions. In order to do that, it is necessary to assure maintenance ofall favorable biological processes in forest ecosystems as required by the recommendation of EU No.1269/99 from June 6,1999. According to that e.g. our government issued an order No.194/2000 which requires to limit application of chain-saw to a certain part of day only due to their noise and replace them by logging machines and hauling forwarders. Until now, quantitative assessment of root injuries by forwarders on the whole tree level could be done only on the basis of labourious studies. Development of new instrumental technology makes it possible to quantify the extent of injuries by sap flow measurement using thermal methods in different parts of conducting systems. This will be done by comparing flows in disturbed and control trees and their"@en .
