The
character of ctl-methods is that the trees are brought to the forest road in
form of short logs.
There are
several ways to do it: (a) Trees are converted into logs directly in the stand
(i.e., felling-delimbing-crosscutting in a smooth single pass). Or (b) trees
can be delimbed inside the stand right after felling, but they are crosscut
into logs after the stem lengths have been pre-skidded to the trail. Or (c) one
may pre-skid full trees to the trail and perform there the delimbing and
cross-cutting – so they are extracted as logs. After extraction (d), the logs
can be transported directly to the factory as such or turned into chips before
transport.
