Snow Distribution Behind Single-Row Field Windbreaks
Single-row windbreaks of Siberian elm (Ulmus pumila L.) trapped too much snow when trees were spaced 5 or 10 feet apart. Even 15-foot spacing, with pruning to a height of 3 feet, was unsatisfactory. When trees were purned to 6 feet, though, the 15-foot spacing gave snow distribution patterns similar to those on open fields. Green ash (Fraxinus pennsylvanica Marsh.) held back too much snow at 5-foot spacing but allowed a fairly uniform spread when spacing was 10 or 15 feet. No pruning was required.
