The role of a shelter belt is to reduce the wind speed on the lee side. A solid wall will do this, but results in wind turbulence on the lee side. The best shelter belt is moderately permeable, so some wind flows through as well as over the trees. Effective shelter will be provided on the lee side for about 10 times the height of the shelter belt.
