What are the benefits of shelterbelts?

Abstract. Field shelterbelts increase yields of field and forage crops throughout the world. The increases are due to reduced wind erosion, improved microclimate, snow retention and reduced crop damage by high winds. Crops differ in their responsiveness to shelter.

How do windbreaks and shelterbelts work?

A very dense windbreak forces wind to be pulled down on the leeward side creating turbulence. As the density of a shelterbelt is reduced, more air passes through the shelterbelt and reduces the amount of turbulence created by the dense windbreak. As a result the extent of the down-wind protected area increases.

Do trees block wind?

Trees, bushes, and shrubs are often planted together to block or impede wind from ground level to the treetops. Evergreen trees combined with a wall, fence, or earth berm (natural or man-made walls or raised areas of soil) can deflect or lift the wind over the home.
