Wide Shelterbelt of Sugar Gum

Despite the clear view under the trees, this wide belt of
direct-seeded Sugar Gum (Eucalyptus cladocaylx) does not appear
to allow the wind to increase in speed as it funnels through
the gap under the canopy. This demonstrates the opportunity
for farmers to overcome the problems of wind tunnelling by
increasing the width of their shelterbelts. Once again the
most sheltered zone is at around 5 times the height of the
trees of about 100m from the belt. Open wind speeds are not
regained until well after 400 metres from the belt.
