the pruning operation to raise the crown
/ canopy. It involves pruning or removal
of branches to increase the distance
between the base of the canopy and ground
level. It is normally carried out to
improve access or provide visibility

should , if possible be carried out
before a tree reaches maturity in order
to avoid large wounds.

Thinning: This
involves the reduction in the density
of the crown. This operation would not
normally be carried
out on conifers, so it is generally
confined to deciduous
broadleaf trees. Trees may be crown
thinned to reduce damage that could
result from crown resistance to strong
winds. Crown thinning may be carried
out to admit more air and light into
and through the canopy.
