Windbreaks are plants or structures designed to slow down and protect sensitive areas from the effects of wind. They are widely used in agriculture to shield crops against strong winds, in landscaping for microclimates, and in town planning reduce wind chill that people may feel when out walking. Windbreaks can be natural, such as rows of trees or shrubs or artificial walls and fences. The effectiveness of a windbreak really depends on its height and thickness; but also the distance from where you want it to protect. Good design of windbreaks will reduce wind speed by 50%, making for better conditions and increased warmth for plant growth.
