Trees for shelter belts or Windbreak Trees are widely used in farming areas to provide protection to livestock and crops. In many areas of Australia it has been common to plant windbreaks around rural houses as well. Coastal areas are another where windbreak trees serve a useful purpose.
Even in the home garden, trees can be used as windbreaks to protect plants that are more susceptible to wind damage as well as provide a generally more sheltered environment.
The choice of trees will depend on the climate, soil and area, as well as the height that is required. Trees that are suited to inland areas, may not be suited to coastal conditions.
In very open areas it is not uncommon to plant trees of different heights to direct the wind up and over, rather that planting a single line of trees.
Choosing windbreak trees
Not all trees are suited for use as windbreaks. Trees that have inherent strength are required. In ideal circumstances a windbreak will consist of a numb of line of trees, smaller trees in front of taller ones facing the prevailing wind, this cause winds to be deflected.
Windbreaks need to be long to be effective, otherwise the wind will just deflect around and eddy at the back of the windbreak. You may also be looking at fire resistant species and frost resistant species.
