shelterbelt

A shelterbelt provides a more intense, thicker protection for man-made structures, livestock, crops, and pasture than a windbreak. While windbreaks are usually long and narrow, a shelterbelt has multiple rows of trees (four or more). They are planted along the edges of a farmstead or around groups of farm buildings to provide a small but intense zone of protection. A shelterbelt usually begins with the lowest-growing species on the side with the most wind exposure; the plantings then increase in size. After the tallest species, the plantings again diminish in size. Because a shelterbelt is wider than a windbreak, it offers an increased area of protection for indigenous species and also provides a wildlife corridor and habitat for other creatures.
