Several years ago, no one promoted planting trees around poultry houses for fear of restricting natural air flow . However, as industry shifts toward tunnel ventilation, blackout and windowless-type housing, this is less of a concern. Overlooked in the past were the potential energy savings of planting trees or windbreaks around houses. Previous research for other applications suggests properly established windbreaks are an energy efficient, natural system that can reduce heating costs as much as 10%-40% and reduce cooling cost by 20%. Strategically placed, trees provide protection during late fall, winter and early spring by reducing wind speed by more than 50%. A 'wind-shadow' of approximately 200 feet is developed on the downwind side of an established windbreak.
