T-classes 1-3, P-classes 1 and 2: At
stands with temporary trails or permanent trials with 20 m spacing, the fully
mechanized ctl-method is best for coniferous trees and for young broadleaf
trees, too.
T-classes 1-3,
P-class 3: Where the 40 m trail spacing is adopted, the almost fully mechanized
ctl-method with auxiliary felling by chainsaw sets the standard.
T-classes 1-3,
P-class 4: At wider trail spacing, which happens mainly in valuable broadleaf
stands, partly mechanized tree length methods are preferred.
T-classes 4
and 5, all P-classes or all T-classes, but P-class 5: Outside trafficable
areas, methods that use the yarder for extraction set the standard.
