Management
for farmland. Most feeder roots for
trees are near to the surface and are
easily injured by compaction,
reducing their effectiveness and thus
tree vigour and growth. Rutting can
sever or seriously injure roots, also
impacting tree vigour and growth and
eventually causing stain or decay in
the tree and even tree mortality or
blow down. Trails that are seriously
rutted may not be suitable to use in
future harvests. Ruts on steep slopes
can funnel surface water runoff,
causing serious erosion problems.
Above ground damage to residual
trees is also of concern. This is
primarily caused by the skidder, or
the logs it is pulling, banging into or
running over other trees on the site.
Serious wounds can potentially result
in reduced tree vigour or even
mortality. Also, wounds to the stems
of residual trees are almost certain to
result in stain and eventually decay.
This increases the amount of cull (the
amount of material not suitable for
lumber) in those logs when they are
eventually harvested. Research has
shown that bigger wounds result in
more cull. Also wounds in contact
with the ground are likely to result in
more defect due to the moister
environment and proximity of soil -
borne decay and stain organisms.
Deugo offered a number of
practical options to reduce logging
damage. The first was timing.
Obviously, rutting and compaction
are more likely to occur during wet
soil conditions. This is often the case
in the spring, which is also when
most active growth occurs and the
cambium layer just under the bark
more easily separated. As a result
trees are more easily injured in the
spring, when a minor impact can
cause a much more serious injury
than might be caused at other times
of the year.
Careful layout of trails can
minimize the amount of trail
coverage in the woodlot reducing the
amount of compaction. Most
skidders carry well over 100 feet of
cable, so there is no need to drive to
