There should be at least two lines in each windbreak. One line should be large trees. The second line, right next to it, can be shorter trees and other plants with leaves. Locally grown trees and plants are considered the best choices for windbreaks.

Studies have shown that some kinds of trees can grow well even if the quality of the land is not very good. One kind of tree is the white pine. Another is the loblolly pine.
Windbreaks not only protect land and crops from the wind. Surplus trees can be cut down and used or sold for wood.

Trees reduce the damaging effects of wind and rain. Their roots help protect soil from being washed away. And trees can provide another service for agriculture. They can provide grazing animals with shade from the sun.
