The technical
conditions of the forest stand are represented by the technogram with
the sides T-class (trafficability due to the moisture of the soil) and P-class
(productivity of the stand). Each stand falls exactly into one field, in the
example it is T3-P3; but under dry or wet conditions it can move to left (dryer,
T2) or right (wet, T4).
As one
possible harvesting method, the functiogram of a almost fully mechanized ctl-method with bogie-tracks is shown. In the ecogram, it has its
optimum at T2-P3, but is good under T3-P3 and limited under T4-P3 and T1-P3.
Matching
both graphs shows that the method is very good under dry conditions, but also good
under normal conditions in this stand. In combination with the ecograms of
other technical options, this may be a basis to select the optimal option.
