systems is prevented to protect downstream
waterways and maintain the dike's working order.
Technical aids are left in place if possible (if they do not
block the waterway) or are available to allow future
crossing if needed.
5. Drive around wet and marshy areas, dead peat
bogs and conservation areas:
Forwarding operations
should take place at a distance that prevents wheel
ruts which might affect the water conditions or damage
the roots of trees in the conservation area. If there is a
need to cross bogs and conservation areas, the ground
should be reinforced with timber and branches, or it is
best to travel the ground when it is frozen.
6. Felling in productive peat bogs: The ground
structure and basic conditions place high demands on
planning and technology. Forwarding operations are
planned so that the inward and outward flow of water is
not affected by avoiding crossings over swampy areas,
natural waterways and dikes as much as possible.
Necessary crossings are carried out according to point
4 above. Basic tracks and access roads are protected
and reinforced with timber and/or branches. If possible,
use machines with lower ground pressure. There are
also band tracks and tyres adapted for peat bog
conditions. If possible, felling should be carried out
when the ground is frozen.
7. Forest residues and tree stumps are only
harvested to the extent that prevents serious
ground damage:
Do not harvest tree stumps in basic
tracks.
